Background: The pandemic rapidly expanded telemedicine, which has persisted as a widely available primary care modality. The uptake of telemedicine among people with dementia specifically in the primary care setting, who have more complex care needs but also benefit from more accessible primary care, is unknown. Objective: Among people with dementia, assess uptake of telemedicine-based primary care in the post-pandemic period and determine associations with key socio-demographic characteristics. Design: Retrospective observational study. Subjects: People with dementia at UCSF and Kaiser Permanente Northern CA (KPNC) with at least one primary care encounter in pre- (3/1/2019-2/29/2020) or post-COVID (3/1/2021-2/28/2022) periods, post-COVID sample: N= 419 individuals (UCSF), N=18,037 (KPNC). Main Measures: Encounter modality: in-person, video telemedicine, or telephone telemedicine. Focal socio-demographic characteristics: age, limited English proficiency, socioeconomic status, driving distance to clinic, and caregiver at encounter. Key Results: There was a large increase in telemedicine among people with dementia in the post-pandemic period at both sites. At KPNC, those with only in-person primary care visits shrunk from 60.47% (pre) to 26.95% (post). At UCSF, the change was even greater: 98.99% to 35.08%. Across both sites, the only measure significantly associated with use of telemedicine was greater driving distance from home to clinic. At KPNC, those over age 90 were most likely to use telemedicine while patients with limited English proficiency and those with a caregiver at the encounter used telemedicine at lower levels. The relationships were similar at UCSF but not statistically significant. Conclusions: Telemedicine use is high for people with dementia in the primary care setting in the post-pandemic period. Those with longer drives to clinic and the oldest patients were most likely to use telemedicine, likely due to challenges traveling to appointments. Still, not all people with dementia used telemedicine equally—particularly those with limited English proficiency. [ABSTRACT FROM AUTHOR]

Background: Homebound older adults have complex social, medical, and financial needs, but little is known about their healthcare utilization and spending. Objective: To characterize healthcare utilization and spending among homebound older adults. Design: Cohort study using National Health and Aging Trends Study data linked to Medicare Fee-for-Service (FFS) claims data. Participants: Adults aged 70 years and older with Medicare FFS coverage (n = 6468). Main Measures: In a person-year analysis, survey-weighted rates and adjusted marginal differences in inpatient, outpatient, and emergency department utilization and spending 12 months post-interview were calculated by homebound status, defined as reporting never or rarely (no more than 1 day/week) leaving home in the last month. Key Results: Compared to the non-homebound, homebound observations had lower annual unadjusted rates of accessing primary care (60.9% vs 71.9%, p < 0.001) and specialist care (61.0% vs 74.9%, p < 0.001) and higher annual rates of emergency department use (54.0% vs 32.6%, p < 0.001) and hospitalization (39.8% vs 19.8%, p < 0.001). Total annual Medicare spending was $11,346 higher among the homebound compared to the non-homebound (p < 0.001). In a single year analysis (2015), homebound older adults accounted for 11.0% of Medicare spending among those over 70 despite making up only 5.7% of this population. 13.6% of the homebound were in the 95th percentile or above of Medicare spending in 2015. In models adjusting for demographic, clinical, and geographic characteristics, homebound status was associated with a decreased likelihood of having an annual primary care or specialist visit and $2226 additional total annual Medicare spending. Conclusions: Homebound older adults use more hospital-based care and less outpatient care than the non-homebound, contributing to higher levels of overall Medicare spending. [ABSTRACT FROM AUTHOR]

Background: Behavioral health (BH) integration in primary care (PC) can potentially improve outcomes and reduce cost of care. While different models of integration exist, evidence from real-world examples is needed to demonstrate the effectiveness and value of integration. This study aimed to evaluate the outcomes of six PC practice sites located in Western New York that implemented a primary care behavioral health (PCBH) integration model. Objective: To assess the impact of PCBH on all-cause healthcare utilization rates. Design: A retrospective observational study based on historical multi-payer health insurance claims data. Claims data were aggregated on a per-member-per-month basis to compare utilization rates among the patients in the PC practice sites that had implemented PCBH to those in the sites that had not yet done so. Participants: The sample included 6768 unique adult health plan members between October 2015 and June 2017 with at least one BH diagnosis code who were attributed to one of the six newly integrated PC practice sites. Interventions: Under the PCBH integration model, BH specialists were embedded in PC practice sites to treat a wide range of BH conditions. Main Measures: Rates of all-cause ED visits and hospital admissions, along with rates of PC provider and BH provider visits. Key Results: PCBH implementation was associated with reductions in the rates of outpatient ED visits (14.2%; p < 0.001) and PC provider visits (12.0%; p < 0.001), as well as with an increased rate of BH provider visits (7.5%; p = 0.018). Conclusions: PCBH integration appears to alter the treatment patterns among patients with BH conditions by shifting patient visits away from ED and PC providers toward BH providers who specialize in treatment of such patients.

Background: The demands for healthcare resources following a COVID-19 diagnosis are substantial, but not currently quantified. Objective: To describe trends in healthcare utilization within 180 days for patients diagnosed with COVID-19 and identify patient factors associated with increased healthcare use. Design: Observational cohort study. Patients: A total of 64,011 patients with a test-confirmed COVID-19 diagnosis from March to September 2020 in a large integrated healthcare system in Southern California. Main Measures: Overall healthcare utilization during the 180 days following COVID-19 diagnosis, as well as encounter types and reasons for visits during the first 30 days. Poisson regression was used to identify patient factors associated with higher utilization. Analyses were performed separately for patients who were and were not hospitalized for COVID-19. Key Results: Healthcare utilization was about twice as high for hospitalized patients compared to non-hospitalized patients in all time periods. The average number of visits was highest in the first 30 days (hospitalized: 12.3 visits/30 person-days; non-hospitalized: 6.6) and gradually decreased over time. In the first 30 days, the majority of healthcare visits were telehealth encounters (hospitalized: 9.0 visits; non-hospitalized: 5.6 visits), and the most prevalent reasons for visits were COVID-related diagnoses, COVID-related symptoms, and respiratory-related conditions. For hospitalized patients, older age (≥65: RR 1.27, 95% CI 1.15–1.41), female gender (RR 1.07, 95% CI 1.05–1.09), and higher BMI (≥40: RR 1.07, 95% CI 1.03–1.10) were associated with higher total utilization. For non-hospitalized patients, older age, female gender, higher BMI, non-white race/ethnicity, former smoking, and greater number of pre-existing comorbidities were all associated with increased utilization. Conclusions: Patients with COVID-19 seek healthcare frequently within 30 days of diagnosis, placing high demands on health systems. Identifying ways to support patients diagnosed with COVID-19 while adequately providing the usual recommended care to our communities will be important as we recover from the pandemic.

Background: Previous work has demonstrated racial/ethnic differences in emergency department (ED) utilization, but less is known about racial/ethnic differences in the experience of care received during an ED visit. Objective: To examine differences in self-reported healthcare utilization and experiences with ED care by patients' race/ethnicity. Design: Adult ED patients discharged to community (DTC) were surveyed (response rate: 20.25%) using the Emergency Department Patient Experience of Care (EDPEC) DTC Survey. Linear regression was used to estimate case-mix-adjusted differences in patient experience between racial/ethnic groups. Participants: 3122 survey respondents who were discharged from the EDs of 50 hospitals nationwide January–March 2016. Main Measures: Six measures: getting timely care, doctor and nurse communication, communication about medications, receipt of sufficient information about test results, whether hospital staff discussed the patient's ability to receive follow-up care, and willingness to recommend the ED. Key Results: Black and Hispanic patients were significantly more likely than White patients to report visiting the ED for an ongoing health condition (40% Black, 30% Hispanic, 28% White, p<0.001), report having visited an ED 3+ times in the last 6 months (26% Black, 25% Hispanic, 19% White, p<0.001), and report not having a usual source of care (19% Black, 19% Hispanic, 8% White, p<0.001). Compared with White patients, Hispanic patients more often reported that hospital staff talked with them about their ability to receive needed follow-up care (+7.2 percentile points, p=0.038) and recommended the ED (+7.2 points, p=0.037); Hispanic and Black patients reported better doctor and nurse communication (+6.4 points, p=0.008; +4 points, p=0.036, respectively). Conclusions: Hispanic and Black ED patients reported higher ED utilization, lacked a usual source of care, and reported better experience with ED care than White patients. Results may reflect differences in care delivery by staff and/or different expectations of ED care among Hispanic and Black patients. [ABSTRACT FROM AUTHOR]

Background: Emergency department (ED) visits contribute substantially to health care expenditures. Case management has been proposed as a strategy to address the medical and social needs of complex patients. However, strong research designs to evaluate the effectiveness of such interventions are limited. Objectives: To evaluate whether a community-based case management program was associated with reduced ED utilization among complex patients. Design: Patients whose risk exceeded a threshold were randomly assigned to a group offered case management or to the control group. Assignment occurred at five intervals between November 2017 and January 2019. Program effectiveness for all assigned patients was assessed using an intention-to-treat effect. Program effectiveness among those who received treatment was assessed using a local average treatment effect, estimated using instrumental variables. Both estimators were adjusted for baseline characteristics using linear models. Participants: Adults over age 18 with at least one health care encounter with Michigan Medicine or St. Joseph Mercy Health System between June 2, 2016, and November 27, 2018. Interventions: Intervention arm participants (n = 486) were offered coordinated case management across medical, mental health, and social service organizations. Control arm participants (n = 409) received usual care. Main Measures: The primary outcome was the number of ED visits in the 6 months following randomization into the study. Secondary outcomes were 6-month counts of inpatient and outpatient visits. Key Results: Of the 486 patients assigned to the intervention, 131 (27%) consented to receive case management. The intention-to-treat effect on ED visits was + 0.14 (95% CI: − 0.27 to + 0.55). The local average treatment effect among those who consented and received case management was + 0.53 (95% CI: − 1.00 to + 2.05). Intention-to-treat and local average treatment effects were not significant for secondary outcomes. Conclusions: The community case management intervention targeting ED visits was not associated with reduced utilization. Future case management interventions may benefit from additional patient engagement strategies and longer evaluation time periods. Trial Registration: Clinicaltrials.gov Identifier: NCT03293160.

Background: While health-related social needs (HRSN) are known to compromise health, work to date has not clearly demonstrated the relationship between clinically acknowledged social needs, via ICD-10 Z-codes, and readmission.Objective: Assess the rate of 30-, 60-, and 90-day readmission by the level of ICD-10-identified social need. In addition, we examined the associations between demographics, social need, hospital characteristics, and comorbidities on 30-day readmission.Design: Retrospective study using the 2017 Nationwide Readmission Database PARTICIPANTS: We identified 5 domains of HRSN from ICD-10 diagnosis codes including employment, family, housing, psychosocial, and socioeconomic status (SES) and identified how many and which an individual was coded with during the year.Main Measures: The proportion of patients with 30-, 60-, and 90-day readmission stratified by the number of HRSN domains with a multivariable logistic regression to examine the relationship between the number/type of and readmission adjusting for sex, age, payer, hospital characteristics, functional limitations, and comorbidities.Key Results: From 13,217,506 patients, only 2.4% had at least one HRSN diagnosis. Among patients without HRSN, 11.5% had a 30-day readmission, compared to 27.0% of those with 1 domain, increasing to 63.5% for patients with codes in 5 domains. Similar trends were observed for 60- and 90-day readmission; 78.7% of patients with documented HRSN in all 5 domains were hospitalized again within 90 days. The adjusted odds ratio for readmission for individuals with all 5 domains was 12.55 (95% CI: 9.04, 17.43). Housing and employment emerged as two of the most commonly documented HRSN, as well as having the largest adjusted odds ratio.Conclusions: There is a dose-response relationship between the number of HRSN diagnoses and hospital readmission. This work calls attention to the need to develop interventions to reduce readmissions for those at social risk and demonstrates the significance of ICD-10 Z-codes in health outcomes studies.

Background: Post-traumatic stress disorder (PTSD) can be exacerbated by subsequent trauma, but it is unclear if symptoms are worsened by impending death. PTSD symptoms, including hyperarousal, negative mood and thoughts, and traumatic re-experiencing, can impact end-of-life symptoms, including pain, mood, and poor sleep. Thus, increased symptoms may lead to increased end-of-life healthcare utilization.Objectives: To determine if veterans with PTSD have increased end-of-life healthcare utilization or medication use and to examine predictors of medication administration.Design: Secondary analysis of a stepped-wedge design implementation trial to improve end-of-life care for Veterans Affairs (VA) inpatients. Outcome variables were collected via direct chart review. Analyses included hierarchical, generalized estimating equation models, clustered by medical center.Subjects: Veterans, inpatient at one of six VA facilities, dying between 2005 and 2011.Main Measures: Emergency room (ER) visits, hospitalizations, and medication administration in the last 7 days of life.Key Results: Of 5341 veterans, 468 (8.76%) had PTSD. Of those, 21.4% (100/468) had major depression and 36.5% (171/468) had anxiety. Veterans with PTSD were younger (mean age 65.4 PTSD, 70.5 no PTSD, p < 0.0001) and had more VA hospitalizations and ER visits in the last 12 months of life (admissions: PTSD 2.8, no PTSD 2.4, p < 0.0001; ER visits: 3.2 vs 2.5, p < 0.0001). PTSD was associated with antipsychotic administration (OR 1.52, 95% CI 1.06-2.18). Major depression (333/5341, 6.2%) was associated with opioid administration (OR 1.348, 95% CI 1.129-1.609) and benzodiazepines (OR 1.489, 95% CI 1.141-1.943). Anxiety disorders (778/5341, 14.6%) were only associated with benzodiazepines (OR 1.598, 95% CI 1.194-2.138).Conclusions: PTSD's association with increased end-of-life healthcare utilization and increased antipsychotic administration in the final days of life suggests increased symptom burden and potential for terminal delirium in individuals with PTSD. Understanding the burden of psychiatric illness and potential risks for delirium may facilitate the end-of-life care for these patients.Trial Registration: NCT00234286. [ABSTRACT FROM AUTHOR]

Background: Post-stroke care delivery may be affected by provider participation in Medicare Shared Savings Program (MSSP) Accountable Care Organizations (ACOs) through systematic changes to discharge planning, care coordination, and transitional care.Objective: To evaluate the association of MSSP with patient outcomes in the year following hospitalization for ischemic stroke.Design: Retrospective cohort SETTING: Get With The Guidelines (GWTG)-Stroke (2010-2014) PARTICIPANTS: Hospitalizations for mild to moderate incident ischemic stroke were linked with Medicare claims for fee-for-service beneficiaries ≥ 65 years (N = 251,605).Main Measures: Outcomes included discharge to home, 30-day all-cause readmission, length of index hospital stay, days in the community (home-time) at 1 year, and 1-year recurrent stroke and mortality. A difference-in-differences design was used to compare outcomes before and after hospital MSSP implementation for patients (1) discharged from hospitals that chose to participate versus not participate in MSSP or (2) assigned to an MSSP ACO versus not or both. Unique estimates for 2013 and 2014 ACOs were generated.Key Results: For hospitals joining MSSP in 2013 or 2014, the probability of discharge to home decreased by 2.57 (95% confidence intervals (CI) = - 4.43, - 0.71) percentage points (pp) and 1.84 pp (CI = - 3.31, - 0.37), respectively, among beneficiaries not assigned to an MSSP ACO. Among discharges from hospitals joining MSSP in 2013, beneficiary ACO alignment versus not was associated with increased home discharge, reduced length of stay, and increased home-time. For patients discharged from hospitals joining MSSP in 2014, ACO alignment was not associated with changes in utilization. No association between MSSP and recurrent stroke or mortality was observed.Conclusions: Among patients with mild to moderate ischemic stroke, meaningful reductions in acute care utilization were observed only for ACO-aligned beneficiaries who were also discharged from a hospital initiating MSSP in 2013. Only 1 year of data was available for the 2014 MSSP cohort, and these early results suggest further study is warranted.Registration: None. [ABSTRACT FROM AUTHOR]

Background: Repetitive inpatient laboratory testing in the face of clinical stability is a marker of low-value care. However, for commonly encountered clinical scenarios on medical units, there are no guidelines defining appropriate use criteria for laboratory tests.Objective: This study seeks to establish consensus-based recommendations for the utilization of common laboratory tests in medical inpatients.Design: This study uses a modified Delphi method. Participants completed two rounds of an online survey to determine appropriate testing frequencies for selected laboratory tests in commonly encountered clinical scenarios. Consensus was defined as agreement by at least 80% of participants.Participants: Participants were 36 experts in internal medicine across Canada defined as internists in independent practice for ≥ 5 years with experience in medical education, quality improvement, or both. Experts represented 8 of the 10 Canadian provinces and 13 of 17 academic institutions.Main Measures: Laboratory tests and clinical scenarios included were those that were considered common on medical units. The final survey contained a total of 45 clinical scenarios looking at the utilization of six laboratory tests (complete blood count, electrolytes, creatinine, urea, international normalized ratio, and partial thromboplastin time). The possible frequency choices were every 2-4 h, 6-8 h, twice a day, daily, every 2-3 days, weekly, or none unless there was specific diagnostic suspicion. These scenarios were reviewed by two internists with training in quality improvement and survey methods.Key Results: Of the 45 initial clinical scenarios included, we reached consensus on 17 scenarios. We reached weak consensus on an additional 19 scenarios by combining two adjacent frequency categories.Conclusions: A Canadian expert panel of internists has provided frequency recommendations on the utilization of six common laboratory tests in medical inpatients. These recommendations need validation in prospective studies to assess whether restrictive versus liberal laboratory test ordering impacts patient outcomes. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effectiveness of Helping Invested Families Improve Veterans' Experiences Study (HI-FIVES), a skills training program for caregivers of persons with functional or cognitive impairments.Design: A two-arm RCT.Setting: Single Veterans Affairs Medical Center.Participants: Patients and their primary caregivers referred in the past 6 months to home and community-based services or geriatrics clinic.Intervention: All caregivers received usual care. Caregivers in HI-FIVES also received five training calls and four group training sessions.Main Measures: Cumulative patient days at home 12 months post-randomization, defined as days not in an emergency department, inpatient hospital, or post-acute facility. Secondary outcomes included patients' total VA health care costs, caregiver and patient rating of the patient's experience of VA health care, and caregiver depressive symptoms.Results: Of 241 dyads, caregivers' (patients') mean age was 61 (73) years, 54% (53%) Black and 89% (4%) female. HI-FIVES was associated with a not statistically significant 9% increase in the rate of days at home (95% CI 0.72, 1.65; mean difference 1 day over 12 months). No significant differences were observed in health care costs or caregiver depressive symptoms. Model-estimated mean baseline patient experience of VA care (scale of 0-10) was 8.43 (95% CI 8.16, 8.70); the modeled mean difference between HI-FIVES and controls at 3 months was 0.29 (p = .27), 0.31 (p = 0.26) at 6 months, and 0.48 (p = 0.03) at 12 months. For caregivers, it was 8.34 (95% CI 8.10, 8.57); the modeled mean difference at 3 months was 0.28 (p = .18), 0.53 (p < .01) at 6 months, and 0.46 (p = 0.054) at 12 months.Conclusions: HI-FIVES did not increase patients' days at home; it showed sustained improvements in caregivers' and patients' experience of VA care at clinically significant levels, nearly 0.5 points. The training holds promise in increasing an important metric of care quality-reported experience with care. [ABSTRACT FROM AUTHOR]

Background: Changing Medicaid fees is a common approach for states to address budget fluctuations, and many currently set Medicaid physician fees at levels lower than Medicare and private insurers. The Affordable Care Act included a temporary Medicaid fee bump for primary care providers (PCPs) in 2013-2014 that recently led to both an increase and then subsequent decrease in PCP fees in many states.Objective: To conduct a systematic literature review on the effects of changing Medicaid fees on provider participation and enrollees' access to care and service use.Methods: We searched PubMed/Medline and JSTOR and identified 18 studies that assessed the longitudinal impact of provider fee changes in Medicaid on the outcomes of interest. We summarized information on study design, methods, and findings.Results: Seven studies examined the impact of fee changes on provider participation in Medicaid. Of these, three studies found that fee increases were associated with positive effects on providers' likelihood of accepting Medicaid patients or on their Medicaid caseloads. Five studies that examined the impact of fee changes on Medicaid enrollees' access to care found a positive association with one or more access measure, such as having a usual source of care or appointment availability. Lastly, eight of 14 studies that examined service use found positive associations between fee changes and at least one measure of use, such as changes in the probability of enrollees having any visit, the number of visits, and shifts in the site of care toward office-based care; others largely did not find significant associations.Conclusions: There is mixed evidence on the impact of changing Medicaid fees on provider participation and enrollees' service use; however, increasing fees appears to have more consistent positive effects on access to care. Whether these improvements in access translate into better health outcomes or downstream cost savings are critical questions. [ABSTRACT FROM AUTHOR]

Background: The Patient-Centered Medical Home (PCMH) has emphasized timely access to primary care, often by using non-traditional modes of delivery, such as care in person after-hours or by phone during or after normal hours. Limited data exists on whether improving patient-reported access with these service types reduces hospitalization.Objective: To examine the association of patient-reported access to primary care within the Veteran Health Administration (VHA) via five service types and hospitalizations for ambulatory care sensitive conditions (ACSCs).Design: Retrospective cohort study, using multivariable logistic regression adjusting for patient demographics, comorbidity, characteristics of patients' area of residence, and clinic-level random effects.Participants: A total of 69,710 VHA primary care patients who responded to the 2012 Survey of Healthcare Experiences of Patients (SHEP), PCMH module.Main Measures: Survey questions captured patients' ability to obtain care from VHA for five service types: routine care, immediate care, after-hours care, care by phone during regular office hours, and care by phone after normal hours. Outcomes included binary measures of hospitalization for overall, acute, and chronic ACSCs in 2013, identified in VHA administrative data and Medicare fee-for-service claims.Key Results: Patients who reported "always" able to obtain after-hours care compared to "never" were less likely to be hospitalized for chronic ACSCs (OR 0.62, 95% CI 0.44-0.89, p = 0.009). Patients reporting "usually" getting care by phone during regular hours were more likely have a hospitalization for chronic ACSC (OR 1.49, 95% CI 1.03-2.17, p = 0.034). Experiences with routine care, immediate care, and care by phone after-hours demonstrated no significant association with hospitalization for ACSCs.Conclusions: Improving patients' ability to obtain after-hours care was associated with fewer hospitalizations for chronic ACSCs, while access to care by phone during regular hours was associated with more hospitalizations. Health systems should consider the benefits, including reduced hospitalizations for chronic ACSCs, against the costs of implementing each of these PCMH services. [ABSTRACT FROM AUTHOR]

Background: Components of substance use disorder (SUD) treatment have been shown to reduce inpatient and emergency department (ED) utilization. However, integrated treatment using pharmacotherapy and recovery coaches in primary care has not been studied.Objective: To determine whether integrated addiction treatment in primary care reduces inpatient and ED utilization and improves outpatient engagement.Design: A retrospective cohort study comparing patients in practices with and without integrated addiction treatment including pharmacotherapy and recovery coaching during a staggered roll-out period.Participants: A propensity score matched sample of 2706 adult primary care patients (1353 matched pairs from intervention and control practices) with a SUD diagnosis code, excluding cannabis or tobacco only, matched on baseline utilization.Intervention: A multi-modal strategy that included forming interdisciplinary teams of local champions, access to addiction pharmacotherapy, counseling, and recovery coaching. Control practices could refer patients to an addiction treatment clinic offering pharmacotherapy and behavioral interventions.Main Measures: The number of inpatient admissions, hospital bed days, ED visits, and primary care visits.Key Results: During the follow-up period, there were fewer inpatient days among the intervention group (997 vs. 1096 days with a mean difference of 7.3 days per 100 patients, p = 0.03). The mean number of ED visits was lower for the intervention group (36.2 visits vs. 42.9 per 100 patients, p = 0.005). There was no difference in the mean number of hospitalizations. The mean number of primary care visits was higher for the intervention group (317 visits vs. 270 visits per 100 patients, p < 0.001). Intervention practices had a greater increase in buprenorphine and naltrexone prescribing.Conclusions: In a non-randomized retrospective cohort study, integrated addiction pharmacotherapy and recovery coaching in primary care resulted in fewer hospital days and ED visits for patients with SUD compared to similarly matched patients receiving care in practices without these services.

Background: Regular primary care visits may allow an opportunity to deliver high-value, proactive care. However, no previous study has examined whether more temporally regular primary care visits predict better outcomes.Objective: To examine the relationship between the temporal regularity of primary care (PC) visits and outcomes.Design: Retrospective cohort study.Participants: We used Medicare claims for 378,862 fee-for-service Medicare beneficiaries, who received PC at 1328 federally qualified health centers from 2010 to 2014.Main Measures: We created five beneficiary groups based upon their annual number of PC visits. We further subdivided those groups according to whether PC visits occurred with more or less regularity than the median value. We compared these 10 subgroups on three outcomes, adjusting for beneficiary characteristics: emergency department (ED) visits, hospitalizations, and total Medicare expenditures. We also aggregated to the clinic level and divided clinics into tertiles of more, less, and similarly regular to predicted. We compared these three groups of clinics on the same three outcomes of care.Key Results: Within each visit frequency group, beneficiaries in the subgroup with fewer regular visits had more ED visits, more hospitalizations, and higher costs. Among beneficiaries with the most frequent PC visits, the less regular subgroup had more ED visits (1.70 vs. 1.31 per person-year), more hospitalizations (0.69 vs. 0.57), and greater Medicare expenditures ($20,731 vs. $17,430, p < 0.001 for all comparisons). Clinics whose PC visits were more regular than predicted also had better outcomes than other clinics, although the effect sizes were smaller.Conclusions: Temporal patterns of PC visits are correlated with outcomes, even among beneficiaries who appear otherwise similar. Measuring the temporal regularity of PC visits may be useful for identifying beneficiaries at risk for adverse events, and as a barometer for and an impetus to clinic-level quality improvement.

Background: U.S. health systems, incentivized by financial penalties, are designing programs such as case management to reduce service utilization among high-cost, high-need populations. The major challenge is identifying patients for whom targeted programs are most effective for achieving desired outcomes.Objective: To evaluate a health system's outpatient complex case management (OPCM) for Medicare beneficiaries for patients overall and for high-risk patients using system-tailored taxonomy, and examine whether OPCM lowers service utilization and healthcare costs.Design: Retrospective case-control study using Medicare data collected between 2012 and 2016 for Ochsner Health System.Participants: Super-utilizers defined as Medicare patients with at least two hospital/ED encounters within 180 days of the index date including the index event.Intervention: Outpatient complex case management.Main Measures: Propensity score-adjusted multivariable logistic regression analysis was conducted for primary outcomes (90-day hospital readmission; 90-day ED re-visit). A difference-in-difference analysis was conducted to examine changes in per membership per month (PMPM) costs based on OPCM exposure.Key Results: Among 18,882 patients, 1197 (6.3%) were identified as "high-risk" and 470 (2.5%) were OPCM participants with median enrollment of 49 days. High-risk OPCM cases compared to high-risk controls had lower odds of 90-day hospital readmissions (0.81 [0.40-1.61], non-significant) and lower odds of 90-day ED re-visits (0.50 [0.32-0.79]). Non-high-risk OPCM cases compared to non-high-risk controls had lower odds of 90-day hospital readmissions (0.20 [0.11-0.36]) and 90-day ED re-visits (0.66 [0.47-0.94]). Among OPCM cases, high-risk patients compared to non-high-risk patients had greater odds of 90-day hospital readmissions (4.44 [1.87-10.54]); however, there was no difference in 90-day ED re-visits (0.99 [0.58-1.68]). Overall, OPCM cases had lower total cost of care compared to controls (PMPM mean [SD]: - $1037.71 [188.18]).Conclusions: Use of risk stratification taxonomy for super-utilizers can identify patients most likely to benefit from case management. Future studies must further examine which OPCM components drive improvements in select outcome for specific populations. [ABSTRACT FROM AUTHOR]

The article presents a study which sought to estimate the prevalence of chronic multisymptom illness (CMI)-related diagnoses and to explore trends in CMI-related outpatient healthcare utilization in the U.S. Veterans Health Administration (VHA). The study concludes that females have a higher prevalence of CMI. The study states that VHA outpatient care utilization was nearly twice as high for Operations Enduring Freedom, Iraqi Freedom, and New Dawn (OEF/OIF/OND) veterans.

Background: Research studies have shown that patient-reported outcome measures (PROMs) that assess global health are helpful for predicting health care utilization, but less evidence exists that collection of PROMs in routine care can identify patients with high health care needs.Objective: To investigate the association between the PROMIS Global Health (PGH) scores and subsequent health care utilization among patients in a large accountable care organization (ACO).Design: Retrospective cohort study of individuals in the Partners HealthCare ACO who completed at least one PGH during a primary care visit.Participants: A total of 2639 individuals who completed at least one PGH and who also had 12 months of ACO membership and/or claims data prior to the PROM completion and at least one month of claims data post-PGH completion.Main Measures: The main outcomes were the rates of emergency department (ED) visits and hospitalizations by quartile of PGH physical and mental health scores. We also compared the predictive accuracy of administrative data models with and without the PGH scores to identify the highest utilizers.Key Results: The group with the worst (lowest) physical and mental health scores had significantly higher rates of hospitalization (RR 5.14, 95% CI 2.37, 11.15; and 2.27, 95% CI 1.06, 4.85, respectively) than those with higher scores. After adjustment for demographic and clinical factors, only the group with lower physical health scores had higher rates of hospitalization (RR 3.15, 95% CI 1.30, 7.90). The addition of the physical health subscore to administrative data increased the sensitivity to detect the top 5% of hospital utilizers compared with administrative data alone (44.0% vs. 36.0% respectively).Conclusions: Worse self-reported physical health, measured during routine primary care, is associated with significantly higher rates of hospitalization. It is not associated with increased rates of ED visits. Self-reported physical health modestly increases the sensitivity to detect the highest hospital utilizers. [ABSTRACT FROM AUTHOR]

Background: Frequent emergency department (ED) users account for a disproportionately high number of ED visits. Studies on case management (CM) interventions to reduce frequent ED use have shown mixed results, and few studies have been conducted within a universal health coverage system.Objective: To determine whether a CM intervention-compared to standard emergency care-reduces ED attendance.Design: Randomized controlled trial.Participants: Two hundred fifty frequent ED users (5 or more visits in the prior 12 months) who visited a public urban ED at the Lausanne University Hospital between May 2012 and July 2013 were allocated to either an intervention (n = 125) or control (n = 125) group, and monitored for 12 months.Interventions: An individualized CM intervention consisting of concrete assistance in obtaining income entitlements, referral to primary or specialty medical care, access to mental health care or substance abuse treatment, and counseling on at-risk behaviors and health care utilization (in addition to standard care) at baseline and 1, 3, and 5 months.Main Measures: We used a generalized linear model for count data (negative binomial distribution) to compare the number of ED visits during the 12-month follow-up between CM and usual care, from an intention-to-treat perspective.Key Results: At 12 months, there were 2.71 (±0.23) ED visits in the intervention group versus 3.35 (±0.32) visits among controls (ratio = 0.81, 95 % CI = 0.63; 1.02). In the multivariate model, the effect of the CM intervention on the number of ED visits approached statistical significance (b = -0.219, p = 0.075). The presence of poor social determinants of health was a significant predictor of ED use in the multivariate model (b = 0.280, p = 0.048).Conclusions: CM may reduce ED use by frequent users through an improved orientation to the health care system. Poor social determinants of health significantly increase use of the ED by frequent users. [ABSTRACT FROM AUTHOR]

Background: The patient-centered medical home (PCMH) model has several components to improve care for patients with high comorbidity, including greater access to face-to-face primary care.Objective: We examined whether high-comorbidity patients had larger increases in primary care provider (PCP) visits attributable to PCMH implementation in a large integrated health system relative to other patients enrolled in primary care.Design, Subjects and Main Measures: This longitudinal study examined a 1 % random sample of 9.3 million patients enrolled in the Veterans Health Administration (VHA) at any time between 2003 and 2013. Face-to-face visits with PCPs per quarter were identified through VHA administrative data. Comorbidity was measured using the Gagne index and patients with a weighted score of ≥ 2 were defined as high comorbidity. We applied interrupted time-series models to estimate marginal changes in PCP visits attributable to PCMH implementation. Differences in marginal changes were calculated across comorbidity groups (high vs. low). Analyses were stratified by age group to account for Medicare eligibility.Key Results: Among age 65+ patients, PCMH was associated with greater PCP visits starting four and ten quarters following implementation for high- and low-comorbidity patients, respectively. Changes were larger for high-comorbidity patients (eight to 11 greater visits per 1000 patients per quarter). Among patients age < 65, PCMH was associated with greater visits for high-comorbidity patients starting eight quarters following implementation, but fewer visits for low-comorbidity patients in all quarters. The difference in visit changes across groups ranged from 18 to 67 visits per 1000 patients per quarter.Conclusions: Increases in PCP visits attributable to PCMH were greater among patients with higher comorbidity. Health systems implementing PCMH should account for population-level comorbidity burden when planning for PCMH-related changes in PCP utilization. [ABSTRACT FROM AUTHOR]

The article focuses on the Preventable Admissions Care Team (PACT) Clinic generated by the Mount Sinai Medical (MSH) Center, East Harlem, New York City to improve the care of complex patients. Topics discussed include the PACT Program, with the goal of reducing readmissions in the Emergency Department (ED), maintaining data on personal information of patients and comorbidity in MSH electronic medical records, regression to the mean (RTM) and designing and addressing RTM in study design.

Background: Many Veterans treated within the VA Healthcare System (VA) are also enrolled in fee-for-service (FFS) Medicare and receive treatment outside the VA. Prior research has not accounted for the multiple ways that Veterans receive services across healthcare systems.Objective: We aimed to establish a typology of VA and Medicare utilization among dually enrolled Veterans with type 2 diabetes.Design: This was a retrospective cohort.Participants: 316,775 community-dwelling Veterans age ≥ 65 years with type 2 diabetes who were dually enrolled in the VA and FFS Medicare in 2008-2009.Methods: Using latent class analysis, we identified classes of Veterans based upon their probability of using VA and Medicare diabetes care services, including patient visits, laboratory tests, glucose test strips, and medications. We compared the amount of healthcare use between classes and identified factors associated with class membership using multinomial regression.Key Results: We identified four distinct latent classes: class 1 (53.9%) had high probabilities of VA use and low probabilities of Medicare use; classes 2 (17.2%), 3 (21.8%), and 4 (7.0%) had high probabilities of VA and Medicare use, but differed in their Medicare services used. For example, Veterans in class 3 received test strips exclusively through Medicare, while Veterans in class 4 were reliant on Medicare for medications. Living ≥ 40 miles from a VA predicted membership in classes 3 (OR 1.1, CI 1.06-1.15) and 4 (OR 1.11, CI 1.04-1.18), while Medicaid eligibility predicted membership in class 4 (OR 4.30, CI 4.10-4.51).Conclusions: Veterans with diabetes can be grouped into four distinct classes of dual health system use, representing a novel way to characterize how patients use multiple services across healthcare systems. This classification has applications for identifying patients facing differential risk from care fragmentation. [ABSTRACT FROM AUTHOR]

Background: Little is known about the factors that influence physicians' admission decisions, especially among lower acuity patients. For the purpose of our study, non-medical refers to all of the factors-other than the patient's clinical condition-that could potentially influence admission decisions.Objective: To describe the influence of non-medical factors on physicians' decisions to admit non-critically ill patients presenting to the ED.Design: Cross-sectional study of hospital admissions at a single academic medical center.Participants: Non-critically ill adult patients admitted to the hospital (n = 297) and the admitting emergency medicine physicians (n = 34).Main Measures: A patient survey assessed non-medical factors, including primary care access and utilization. A physician survey assessed clinical and non-medical factors influencing the decision to admit. Based on physician responses, admissions were characterized as "strongly acuity-driven," "moderately acuity-driven," or "weakly acuity-driven." Among these admission types, we compared length of stay, cost, and readmission within 30 days to the hospital or ED.Key Results: Based on the admitting physician's assessment, we categorized the motivation for admission as strongly acuity-driven in 185 (62 %) admissions, moderately acuity-driven in 92 (31 %), and weakly acuity-driven in 20 (7 %). Per the physician surveys, 51 % of hospitalizations were strongly or moderately influenced by one or more non-medical factors, including lack of information about baseline conditions (23 %); inadequate access to outpatient specialty care (14 %); need for a diagnostic testing or procedure (12 %); a recent ED visit (11 %); and inadequate access to primary care (10 %). Compared with strongly-acuity driven admissions, admissions that were moderately or weakly acuity-driven were shorter and less costly but were associated with similar rates of ED (35 %) and hospital (27 %) readmission.Conclusions: Non-medical factors are influential in the admission decisions for many patients presenting to the emergency department. Moderately and weakly acuity-driven admissions may represent a feasible target for alternative care pathways. [ABSTRACT FROM AUTHOR]

The article presents a study which examined the rates of healthcare utilization among patients who developed dementia while enrolled in the Adult Changes in Thought (ACT) research between 1994 and 2014. The variables considered include patients with diagnosed and undiagnosed dementia, number of outpatient visits, emergency department visits and hospitalizations. The correlation between dementia and comorbidity is assessed.

Background: The disruption in provider continuity caused by medical resident graduation may result in adverse patient outcomes.Objective: Our aim was to investigate whether resident graduation was associated with increased acute care utilization by residents' primary care patients.Design and Participants: This was a retrospective cohort study of patients cared for by junior and senior residents finishing the academic year in 2010, 2011 and 2012.Main Measures: We compared rates of clinic visits, emergency department (ED) visits, and hospitalizations between transitioning patients whose residents were graduating and non-transitioning patients whose residents were not graduating.Key Results: Our study population comprised 90 residents, 4018 unique patients, and 5988 resident-patient dyads that transitioned (n = 3136) or did not transition (n = 2852). For transitioning patients, the clinic visit rate per 100 patients in the 4 months before and after graduation was 129 and 102, respectively; for non-transitioning patients, the clinic visit rate was 119 and 94, respectively (difference-in-differences, +2 per 100 patients; p = 0.12). For transitioning patients, the ED visit rate per 100 patients before and after graduation was 29 and 26, respectively; for non-transitioning patients, the ED visit rate was 28 and 25, respectively (difference-in-differences, 0; p = 0.49). For transitioning patients, the hospitalization rate per 100 patients before and after graduation was 14 and 13, respectively; for non-transitioning patients, the hospitalization rate was 15 and 12, respectively (difference-in-differences, -2; p = 0.20). In multivariable modeling there was no increased risk for transitioning patients for clinic visits (adjusted rate ratio [aRR], 1.03; 95 % confidence interval [CI], 0.97 to 1.10), ED visits (aRR, 1.05; 95 % CI, 0.92 to 1.20), or hospitalizations (aRR, 1.04; 95 % CI, 0.83 to 1.31).Conclusions: Acute care utilization by residents' patients did not increase or decrease after graduation. Acute care utilization was high before and after graduation. Interventions to decrease the need for acute care should be employed throughout the year. [ABSTRACT FROM AUTHOR]

BACKGROUND: Inappropriate use of colorectal cancer (CRC) screening procedures can inflate healthcare costs and increase medical risk. Little is known about the prevalence or causes of inappropriate CRC screening. OBJECTIVE: Our aim was to estimate the prevalence of potentially inappropriate CRC screening, and its association with patient and facility characteristics in the Veterans Health Administration (VHA) . DESIGN AND PARTICIPANTS: We conducted a cross-sectional study of all VHA patients aged 50 years and older who completed a fecal occult blood test (FOBT) or a screening colonoscopy between 1 October 2009 and 31 December 2011 ( n = 1,083,965). MAIN MEASURES: Measures included: proportion of patients whose test was classified as potentially inappropriate; associations between potentially inappropriate screening and patient demographic and health characteristics, facility complexity, CRC screening rates, dependence on FOBT, and CRC clinical reminder attributes. KEY RESULTS: Of 901,292 FOBT cases, 26.1 % were potentially inappropriate (13.9 % not due, 7.8 % limited life expectancy, 11.0 % receiving FOBT when colonoscopy was indicated). Of 134,335 screening colonoscopies, 14.2 % were potentially inappropriate (10.4 % not due, 4.4 % limited life expectancy). Each additional 10 years of patient age was associated with an increased likelihood of undergoing potentially inappropriate screening (ORs = 1.60 to 1.83 depending on screening mode). Compared to facilities scoring in the bottom third on a measure of reliance on FOBT (versus screening colonoscopy), facilities scoring in the top third were less likely to conduct potentially inappropriate FOBTs (OR = 0.,78) but more likely to conduct potentially inappropriate colonoscopies (OR = 2.20). Potentially inappropriate colonoscopies were less likely to be conducted at facilities where primary care providers were assigned partial responsibility (OR = 0.74) or full responsibility (OR = 0.73) for completing the CRC clinical reminder. CONCLUSIONS: A substantial number of VHA CRC screening tests are potentially inappropriate. Establishing processes that enforce appropriate screening intervals, triage patients with limited life expectancies, and discourage the use of FOBTs when a colonoscopy is indicated may reduce inappropriate testing.

Background: Headache is a frequent complaint and among the most common reasons for visiting a physician. Objective: To characterize trends from 1999 through 2010 in the management of headache. Design: Longitudinal trends analysis. Data: Nationally representative sample of visits to clinicians for headache from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, excluding visits with 'red flags,' such as neurologic deficit, cancer, or trauma. Main Measures: Use of advanced imaging (CT/MRI), opioids/barbiturates, and referrals to other physicians (guideline-discordant indicators), as well as counseling on lifestyle modifications and use of preventive medications including verapamil, topiramate, amitriptyline, or propranolol (guideline-concordant during study period). We analyzed results using logistic regression, adjusting for patient and clinician characteristics, and weighted to reflect U.S. population estimates. Additionally, we stratified findings based on migraine versus non-migraine, acute versus chronic symptoms, and whether the clinician self-identified as the primary care physician. Key Results: We identified 9,362 visits for headache, representing an estimated 144 million visits during the study period. Nearly three-quarters of patients were female, and the mean age was approximately 46 years. Use of CT/MRI rose from 6.7 % of visits in 1999-2000 to 13.9 % in 2009-2010 (unadjusted p < 0.001), and referrals to other physicians increased from 6.9 % to 13.2 % ( p = 0.005). In contrast, clinician counseling declined from 23.5 % to 18.5 % ( p = 0.041). Use of preventive medications increased from 8.5 % to 15.9 % ( p = 0.001), while opioids/barbiturates remained unchanged, at approximately 18 %. Adjusted trends were similar, as were results after stratifying by migraine versus non-migraine and acute versus chronic presentation. Primary care clinicians had lower odds of ordering CT/MRI (OR 0.56 [0.42, 0.74]). Conclusions: Contrary to numerous guidelines, clinicians are increasingly ordering advanced imaging and referring to other physicians, and less frequently offering lifestyle counseling to their patients. The management of headache represents an important opportunity to improve the value of U.S. healthcare. [ABSTRACT FROM AUTHOR]

BACKGROUND: Effective care of young people with rare conditions requires ongoing coordinated medical treatment as well as educational and social support services. However, information on treatment is often lacking due to limited data. South Carolina has a repository of comprehensive health and human service data with which individuals may be tracked across the data systems of multiple state agencies and organizations. OBJECTIVE: To develop a method for studying health care of young persons with rare conditions using this repository. METHODS: We identified individuals aged 15 to 24 years diagnosed during 2000-2010 with Fragile X syndrome (FXS), spina bifida (SB), or muscular dystrophy (MD) using a series of algorithms. ICD-9-CM codes were used to initially identify the cohort from medical billing data. Demographics, medical care, employment, education, and socioeconomic status data were then extracted from linked administrative sources. RESULTS: We identified 1,040 individuals with these rare conditions: 125 with FXS, 695 with SB, and 220 with MD. The vast majority of the cases (95 %) were identified in the Medicaid database. Half of the cohort was male, with a higher percentage in the FXS and MD groups. Sixty-two percent of the cohort was enrolled in the last year of high school. Over half of the cohort received support services from the state's disability and special-needs agency; 16 % received food assistance. Thirty-eight percent were employed at some point during the study period. Forty-nine individuals with SB and 56 with MD died during the study period. CONCLUSIONS: We used a linked statewide data system to study rare conditions. Strengths include the diversity of information, rigorous identification strategies, and access to longitudinal data. Despite limitations inherent to administrative data, we found that linked state data systems are valuable resources for investigating important public health questions on rare conditions.

With its focus on holistic approaches to patient care, caregiver support, and delivery system redesign, geriatrics has advanced our understanding of optimal care during transitions. This article provides a framework for incorporating geriatrics principles into care transition activities by discussing the following elements: (1) identifying factors that make transitions more complex, (2) engaging care 'receivers' and tailoring home care to meet patient needs, (3) building 'recovery plans' into transitional care, (4) predicting and avoiding preventable readmissions, and (5) adopting a palliative approach, when appropriate, that optimizes patient and family goals of care. The article concludes with a discussion of practical aspects of designing, implementing, and evaluating care transitions programs for those with complex care needs, as well as implications for public policy.

BACKGROUND: Post-traumatic stress disorder (PTSD) is common in women veterans (WVs), and associated with significant co-morbidity. Effective treatment is available; however, PTSD is often unrecognized. OBJECTIVES: Identify PTSD prevalence and mental healthcare (MHC) use in a representative national WV sample. DESIGN AND PARTICIPANTS: Cross-sectional, population-based 2008-2009 national survey of 3,611 WVs, weighted to the population. MAIN MEASURES: We screened for PTSD using a validated instrument, and also assessed demographic characteristics, health characteristics, and MHC use in the prior 12 months. Among those screening positive, we conducted multivariate logistic regression to identify independent predictors of MHC use. KEY RESULTS: Overall, 13.0 % (95 % confidence interval [CI] 9.8-16.2) of WVs screened PTSD-positive. Veterans Health Administration (VA) healthcare was used by 31.1 % of PTSD-positives and 11.4 % of PTSD-negatives ( p < 0.001). Among those screening positive, 48.7 % (95 % CI 35.9-61.6) used MHC services (66.3 % of VA-users, 40.8 % of VA-nonusers; p < 0.001). Having a diagnosis of depression (OR = 8.6; 95 % CI 1.5-48.9) and VA healthcare use (OR = 2.7; 95 % CI 1.1-7.0) predicted MHC use, whereas lacking a regular provider for health care (OR = 0.2; 95 % CI 0.1-0.4) and household income below the federal poverty level (OR = 0.2; 95 % CI 0.1-0.5) predicted nonuse. CONCLUSIONS: More than one in eight WVs screened positive for PTSD. Though a majority of VA-users received MHC, low income predicted nonuse. Only a minority of VA-nonusers received MHC. The majority of WVs use non-VA healthcare providers, who may be unaware of their veteran status and PTSD risk. VA outreach to educate VA-nonusers and their healthcare providers about WVs' PTSD risk and available evidence-based VA treatment options is one approach to extend the reach of VA MHC. Research to characterize barriers to VA MHC use for VA-nonusers and low income VA-users is warranted to better understand low service utilization, and to inform program development to engage more WVs in needed MHC.

BACKGROUND: Limited health literacy is associated with poor outcomes in many chronic diseases, but little is known about health literacy in chronic obstructive pulmonary disease (COPD). OBJECTIVE: To examine the associations between health literacy and both outcomes and health status in COPD. PARTICIPANTS, DESIGN AND MAIN MEASURES: Structured interviews were administered to 277 subjects with self-report of physician-diagnosed COPD, recruited through US random-digit telephone dialing. Health literacy was measured with a validated three-item battery. Multivariable linear regression, controlling for sociodemographics including income and education, determined the cross-sectional associations between health literacy and COPD-related health status: COPD Severity Score, COPD Helplessness Index, and Airways Questionnaire-20R [measuring respiratory-specific health-related quality of life (HRQoL)]. Multivariable logistic regression estimated associations between health literacy and COPD-related hospitalizations and emergency department (ED) visits. KEY RESULTS: Taking socioeconomic status into account, poorer health literacy (lowest tertile compared to highest tertile) was associated with: worse COPD severity (+2.3 points; 95 % CI 0.3-4.4); greater COPD helplessness (+3.7 points; 95 % CI 1.6-5.8); and worse respiratory-specific HRQoL (+3.5 points; 95 % CI 1.8-4.9). Poorer health literacy, also controlling for the same covariates, was associated with higher likelihood of COPD-related hospitalizations (OR = 6.6; 95 % CI 1.3-33) and COPD-related ED visits (OR = 4.7; 95 % CI 1.5-15). Analyses for trend across health literacy tertiles were statistically significant ( p < 0.05) for all above outcomes. CONCLUSIONS: Independent of socioeconomic status, poor health literacy is associated with greater COPD severity, greater COPD helplessness, worse respiratory-specific HRQoL, and higher odds of COPD-related emergency health-care utilization. These results underscore that COPD patients with poor health literacy may be at particular risk for poor health-related outcomes. [ABSTRACT FROM AUTHOR]

BACKGROUND: Policy-makers have called for efforts to reduce overuse of cancer screening tests, including colorectal cancer screening (CRCS). Overuse of CRCS tests other than colonoscopy has not been well documented. OBJECTIVE: To estimate levels and correlates of fecal occult blood test (FOBT) overuse in a national Veterans Health Administration (VHA) sample. DESIGN: Observational PARTICIPANTS: Participants included 1,844 CRCS-eligible patients who responded to a 2007 CRCS survey conducted in 24 VHA facilities and had one or more FOBTs between 2003 and 2009. MAIN MEASURES: We combined survey data on race, education, and income with administrative data on region, age, gender, CRCS procedures, and outpatient visits to estimate overuse levels and variation. We coded FOBTs as overused if they were conducted <10 months after prior FOBT, <9.5 years after prior colonoscopy, or <4.5 years after prior barium enema. We used multinomial logistic regression models to examine variation in overuse by reason (sooner than recommended after prior FOBT; sooner than recommended after colonoscopy, barium enema, or a combination of procedures), adjusting for clustering of procedures within patients, and patients within facilities. KEY RESULTS: Of 4,236 FOBTs received by participants, 885 (21 %) met overuse criteria, with 323 (8 %) sooner than recommended after FOBT, and 562 (13 %) sooner than recommended after other procedures. FOBT overuse varied across facilities (9-32 %, p < 0.0001) and region (12-23 %, p < .0012). FOBT overuse after prior FOBT declined between 2003 and 2009 (8 %-5 %, p = .0492), but overuse after other procedures increased (11-19 %, p = .0002). FOBT overuse of both types increased with number of outpatient visits (OR 1.15, p < 0.001), but did not vary by patient demographics. More than 11 % of overused FOBTs were followed by colonoscopy within 12 months. CONCLUSIONS: Many FOBTs are performed sooner than recommended in the VHA. Variation in overuse by facility, region, and outpatient visits suggests addressing FOBT overuse will require system-level solutions. [ABSTRACT FROM AUTHOR]

Background: High-deductible health plans (HDHPs) are an increasingly common strategy to contain health care costs. Individuals with chronic conditions are at particular risk for increased out-of-pocket costs in HDHPs and resulting cost-related underuse of essential health care. Objective: To evaluate whether families with chronic conditions in HDHPs have higher rates of delayed or forgone care due to cost, compared with those in traditional health insurance plans. Design: This mail and phone survey used multiple logistic regression to compare family-level rates of reporting delayed/forgone care in HDHPs vs. traditional plans. Participants: We selected families with children that had at least one member with a chronic condition. Families had employer-sponsored insurance in a Massachusetts health plan and >12 months of enrollment in an HDHP or a traditional plan. Main Measures: The primary outcome was report of any delayed or forgone care due to cost (acute care, emergency department visits, chronic care, checkups, or tests) for adults or children during the prior 12 months. Results: Respondents included 208 families in HDHPs and 370 in traditional plans. Membership in an HDHP and lower income were each independently associated with higher probability of delayed/forgone care due to cost. For adult family members, the predicted probability of delayed/forgone care due to cost was higher in HDHPs than in traditional plans [40.0% vs 15.1% among families with incomes <400% of the federal poverty level (FPL) and 16.0% vs 4.8% among those with incomes ≥400% FPL]. Similar associations were observed for children. Conclusions: Among families with chronic conditions, reporting of delayed/forgone care due to cost is higher for both adults and children in HDHPs than in traditional plans. Families with lower incomes are also at higher risk for delayed/forgone care. [ABSTRACT FROM AUTHOR]

BACKGROUND: Although surveillance for hepatocellular carcinoma (HCC) is recommended in high-risk patients, several studies have suggested it is being underutilized in clinical practice. The aim of our study was to quantify utilization rates for HCC surveillance among patients with cirrhosis and summarize patterns of association between utilization rates and patient socio-demographic characteristics. DATA SOURCES: We performed a systematic literature review using the Medline database from January 1990 through March 2011 and a manual search of national meeting abstracts from 2008-2010. METHODS: Two investigators independently extracted data on patient populations, study methods, and results using standardized forms. A pooled surveillance rate with 95% confidence intervals was calculated. Pre-specified subgroup analysis was performed to find correlates of surveillance utilization. RESULTS: We identified nine studies that met inclusion criteria. The pooled surveillance rate was 18.4% (95%CI 17.8%-19.0%). Surveillance rates were significantly higher among patients followed in subspecialty gastroenterology clinics compared to those followed in primary care clinics (51.7% vs. 16.9%, p < 0.001). Non-Caucasians and patients of low socioeconomic status had lower surveillance rates than their counterparts. CONCLUSIONS: Utilization rates for HCC surveillance are low, although they are significantly higher among patients followed in subspecialty clinics. Current studies fail to determine why HCC surveillance is not being performed. Future efforts should focus on identifying appropriate intervention targets to increase surveillance rates and reduce socio-demographic disparities. [ABSTRACT FROM AUTHOR]

Background: Over 35% of returned Iraq and Afghanistan veterans in VA care have received mental health diagnoses; the most prevalent is post-traumatic stress disorder (PTSD). Little is known about these patients' use of non-mental health medical services and the impact of mental disorders on utilization.Objective: To compare utilization across three groups of Iraq and Afghanistan veterans: those without mental disorders, those with mental disorders other than PTSD, and those with PTSD.Design and Participants: National, descriptive study of 249,440 veterans newly utilizing VA healthcare between October 7, 2001 and March 31, 2007, followed until March 31, 2008.Measurements: We used ICD9-CM diagnostic codes to classify mental health status. We compared utilization of outpatient non-mental health services, primary care, medical subspecialty, ancillary services, laboratory tests/diagnostic procedures, emergency services, and hospitalizations during veterans' first year in VA care. Results were adjusted for demographics and military service and VA facility characteristics.Main Results: Veterans with mental disorders had 42-146% greater utilization than those without mental disorders, depending on the service category (all P < 0.001). Those with PTSD had the highest utilization in all categories: 71-170% greater utilization than those without mental disorders (all P < 0.001). In adjusted analyses, compared with veterans without mental disorders, those with mental disorders other than PTSD had 55% higher utilization of all non-mental health outpatient services; those with PTSD had 91% higher utilization. Female sex and lower rank were also independently associated with greater utilization.Conclusions: Veterans with mental health diagnoses, particularly PTSD, utilize significantly more VA non-mental health medical services. As more veterans return home, we must ensure resources are allocated to meet their outpatient, inpatient, and emergency needs. [ABSTRACT FROM AUTHOR]

Background: The impact of open access (OA) scheduling on chronic disease care and outcomes has not been studied.Objective: To assess the effect of OA implementation at 1 year on: (1) diabetes care processes (testing for A1c, LDL, and urine microalbumin), (2) intermediate outcomes of diabetes care (SBP, A1c, and LDL level), and (3) health-care utilization (ED visits, hospitalization, and outpatient visits).Methods: We used a retrospective cohort study design to compare process and outcomes for 4,060 continuously enrolled adult patients with diabetes from six OA clinics and six control clinics. Using a generalized linear model framework, data were modeled with linear regression for continuous, logistic regression for dichotomous, and Poisson regression for utilization outcomes.Results: Patients in the OA clinics were older, with a higher percentage being African American (51% vs 34%) and on insulin. In multivariate analyses, for A1c testing, the odds ratio for African-American patients in OA clinics was 0.47 (CI: 0.29-0.77), compared to non-African Americans [OR 0.27 (CI: 0.21-0.36)]. For urine microablumin, the odds ratio for non-African Americans in OA clinics was 0.37 (CI: 0.17-0.81). At 1 year, in adjusted analyses, patients in OA clinics had significantly higher SBP (mean 6.4 mmHg, 95% CI 5.4 - 7.5). There were no differences by clinic type in any of the three health-care utilization outcomes.Conclusion: OA scheduling was associated with worse processes of care and SBP at 1 year. OA clinic scheduling should be examined more critically in larger systems of care, multiple health-care settings, and/or in a randomized controlled trial. [ABSTRACT FROM AUTHOR]

BACKGROUND: Whether having a stable and predictable lifestyle is associated with health care use and health status among HIV patients is unknown. OBJECTIVE: To develop and test the reliability and validity of a measure of life chaos for adults with HIV and examine its association with health care use and health status. DESIGN: Prospective cohort study. PARTICIPANTS: Two hundred twenty HIV-infected persons recruited from those who tested positive hi a mobile testing van and from HIV clinics serving low-income populations. MEASUREMENTS: Participants completed a survey every 6 months, assessing their health care use, SF-12 mental and physical health status and life chaos. RESULTS: Cronbach's alpha for the six-item measure of chaos was .67. Those without a spouse or partner and those with one or more unmet social service needs, such as housing or transportation, had higher chaos scores. Compared to those with less chaos, those with more chaos were less likely to have two or more outpatient visits (adjusted odds ratio [OR] 0.48, 95% confidence interval [CI]: 0.24-0.98), more likely to have two or more missed visits (adjusted OR 2.30, 95%CI: 1.20-4.41) in the 6 months before study enrollment and had lower mental health status at enrollment and at follow-up. Life chaos was not associated with emergency department visits or physical health status. CONCLUSIONS: We created a new measure of life chaos, which was associated with outpatient visits and mental health status. Chaos may be an important barrier to regular medical care. Future studies need to test this measure in more diverse populations and those with other diseases. [ABSTRACT FROM AUTHOR]

BACKGROUND: β-Blockers reduce mortality in patients with systolic chronic heart failure (CHF), yet prescription rates have remained low among primary care providers. OBJECTIVE: To determine the β-blocker prescription rate among patients with systolic CHF at primary care Veterans Affairs (VA) clinics, its change over time; and to determine factors associated with nonprescription. DESIGN: Retrospective chart review. SUBJECTS: Seven hundred and forty-five patients with diagnostic codes for CHF followed in primary care clinics at 3 urban VA Medical Centers. MEASUREMENTS: Rate of β-blocker prescription and comparison of patient characteristics between those prescribed versus those not prescribed β-blockers. RESULTS: Only 368 (49%) had documented systolic CHF. Eighty-two percent (303/368) of these patients were prescribed a β-blocker. The prescription rate rose steadily over 3 consecutive 2-year time periods. Patients with more severely depressed ejection fractions were more likely to be on a β-blocker than patients with less severe disease. Independent predictors of nonprescription included chronic obstructive pulmonary disease, asthma, depression, and age. Patients under 65 years old were 12 times more likely to receive β-blockers than those over 85. CONCLUSION: Primary care providers at VA Medical Centers achieved high rates of β-blocker prescription for CHF patients. Subgroups with relative contraindications had lower prescription rates and should be targeted for quality improvement initiatives. [ABSTRACT FROM AUTHOR]

Background: Women with posttraumatic stress disorder (PTSD) report poor health, but associations with health care utilization are understudied.Objective: To determine associations between medical/surgical utilization and PTSD in female Veterans Affairs (VA) patients.Design: Prospective comparison of utilization rates between women screening positive or negative for PTSD on a mailed survey.Subjects: Women receiving care at an urban VA medical center between October 1996 and January 2000.Measurements: Survey responses, including a validated screen for PTSD (PCL-C), and VA utilization data through September 2002.Results: Two thousand five hundred and seventy-eight (2,578) women (78% of those eligible) completed the PCL-C; 858 (33%) of them screened positive for PTSD (PTSD+). In unadjusted models, PTSD+ women had higher rates of medical/surgical hospitalizations and surgical inpatient procedures. Among women ages 35 to 49, mean days hospitalized/100 patients/year was 43.4 (95% CI 26 to 61) for PTSD+ women versus 17.0 (16 to 18) for PTSD negative (PTSD-) women. More PTSD+ women underwent surgical procedures (P<.001). Mean annual outpatient visits were significantly higher among PTSD+ women, including: emergency department (ED) (1.1 [1.0 to 1.2] vs 0.6 [0.5 to 0.6]), primary care (3.2 [3.0 to 3.4] vs 2.2 [2.1 to 2.3]), medical/surgical subspecialists (2.1 [1.9 to 2.3] vs 1.5 [1.4 to 1.6]), ancillary services (4.1 [3.7 to 4.5] vs 2.4 [2.2 to 2.6]), and diagnostic tests (5.6 [5.1 to 6.1] vs 3.7 [3.4 to 4.0]). In multivariate models adjusted for demographics, smoking, service access, and medical comorbidities, PTSD+ women had greater likelihood of medical/surgical hospitalization (OR=1.37 [1.04 to 1.79]) and of being among the top quartile of patients for visits to the ED, primary care, ancillary services, and diagnostic testing.Conclusions: Female veterans who screen PTSD+ receive more VA medical/surgical services. Appropriateness of that care deserves further study. [ABSTRACT FROM AUTHOR]

Objectives: E-mail communication between patients and their providers has diffused slowly in clinical practice. To address concerns about the use of this technology, we performed a randomized controlled trial of a triage-based e-mail system in primary care. DESIGN AND PATIENTS/PARTICIPANTS: Physicians in 2 university-affiliated primary care centers were randomized to a triage-based e-mail system promoted to their patients. E-mails from patients of intervention physicians were routed to a central account and parsed to the appropriate staff for response. Control group physicians and their patients did not have access to the system. We collected information on patient e-mail use, phone calls, and visit distribution by physician over the 10 months and performed physician and patient surveys to examine attitudes about communication.Results: E-mail volume was greater for intervention versus control physicians (46 weekly e-mails per 100 scheduled visits vs 9 in the control group at the study midpoint; P <.01) but there were no between-group differences in phone volume (67 weekly phone calls per 100 scheduled visits vs 55 in the control group; P =.45) or rates of patient no-shows (5% in both groups; P =.77). Intervention physicians reported more favorable attitudes toward electronic communication than did control physicians but there were no differences in attitudes toward patient or staff communication in general. There were few between-group differences in patient attitudes toward electronic communication or communication in general.Conclusions: E-mail generated through a triage-based system did not appear to substitute for phone communication or to reduce visit no-shows in a primary care setting. Physicians' attitudes toward electronic communication were improved, but physicians' and patients' attitudes toward general communication did not change. Growth of e-mail communication in primary care settings may not improve the efficiency of clinical care. [ABSTRACT FROM AUTHOR]

Objectives: Papanicolaou (Pap) smears are an underutilized screening modality among racial and ethnic minorities. However, no data exist on Pap smear utilization among South Asians, a rapidly growing population in the United States, whose country of origin includes India, Pakistan, Bangladesh, and Sri Lanka. We determined rates and identified variables associated with Pap smear receipt by South Asians.Design: A self-administered survey instrument was mailed to a random sample of South Asians nationwide over a 3-month time period. South Asian households were identified by surnames that were used to search white pages in telephone directories, Department of Motor Vehicle records, and voter registries. Questions regarding Pap smear receipt were taken from the 1999 National Health Interview Survey. Sociodemographic information and measures of acculturation were obtained.Participants: A nationwide nonprobability sample of South Asian women.Intervention: Cross-sectional observational study.Measurements and Main Results: The overall response rate was 42%. In this sample, South Asians belonged to a high socioeconomic strata (SES), with 45% having a household income of >$80,000 and 42% having a master's degree. Three quarters of the respondents (73%) reported having a Pap smear in the last 3 years. In multivariate logistic regression analysis, South Asian women had greater odds of having had a Pap smear if they were married (P <.001), more educated (P =.004), had a usual source of care (P =.002), and were more acculturated (P =.004).Conclusions: Despite the high SES of South Asian women, their rates of Pap smear receipt were lower than national recommendations. Marital status, socioeconomic status, and acculturation are all associated with Pap smear receipt. South Asian communities should be targeted for outreach to promote Pap smear utilization.

Objective: To determine how frequently veterans use non-Department of Veterans Affairs (VA) sources of care in addition to primary care provided by the VA and to assess the association of this pattern of "dual use" to patient characteristics and satisfaction with VA care.Design: Cross-sectional telephone survey of randomly selected patients from four VA medical centers.Participants: Of 1,240 eligible veterans, 830 (67%) participated in the survey.Measurements and Main Results: Survey data were used to assess whether a veteran reported receiving primary care from both VA and non-VA sources of care, as well as the proportion of all primary care visits made to non-VA providers. Of 577 veterans who reported VA primary care visits, 159 (28%) also reported non-VA primary care visits. Among these dual users the mean proportion of non-VA primary care visits was 0.50. Multivariate analysis revealed that the odds of dual use were reduced for those without insurance (odds ratio [OR] 0.34; 95% confidence interval [CI] 0.18, 0.66) and with less education (OR 0.60; 95% CI 0.38, 0.92), while increased for those not satisfied with VA care (OR 2.40; 95% CI 1.40, 4.13). Among primary care dual users, the proportion of primary care visits made to non-VA providers was decreased for patients with heart disease ( p <.05) and patients with alcohol or drug dependence ( p <.05).Conclusions: Primary care dual use was common among these veterans. Those with more education, those with any type of insurance, and those not satisfied with VA care were more likely to be dual users. Non-VA care accounted for approximately half of dual users' total primary care visits. [ABSTRACT FROM AUTHOR]

Objective: To determine whether gender is associated with the use of ancillary services in hospitalized patients.Design: A retrospective study of laboratory and radiology tests ordered for medical and surgical inpatients over 16-month and 20-month periods, respectively. Obstetric patients were excluded.Measurements and Main Results: Number of clinical laboratory and radiology tests per admission, their associated charges, and total charges per admission were measured. In crude analyses, women had 16.5% fewer clinical laboratory tests (p < .0001) with 18.8% lower associated charges (p < .0001) and 24.4% fewer radiology tests (p < .0001) with 15.6% lower associated charges (p < .0001) than men. Total changes for the admission were lower for women in both the clinical laboratory study period ($16,178 vs $18,912, p < .0001) and the radiology study period ($14,621 vs $18,182, p < .0001). When adjusted for age, race, insurance status, service, diagnosis-related-group weight, and length of stay, these differences were smaller but persisted: women had 3.7% fewer laboratory tests performed (p < .001) with 4.8% lower associated charges (p < .001). In similarly adjusted analyses for radiology studies, women received 10.4% fewer radiology examinations (p < .001), with 4.1% lower associated charges (p < .01). There were no significant differences in the adjusted total charges in the laboratory group ($17,450 vs $17,655, p = .20) and only a marginally significant difference in the radiology group ($16,278 vs $16,498, p = .05). When we compared ancillary utilization within the five largest diagnosis-related groups, these differences persisted.Conclusions: Men receive more ancillary services than women, even after adjusting for potential confounders.

Objective: To study the effects of three approaches to increasing utilization of screening mammography in a public hospital setting in Northwest Louisiana.Design: Randomized intervention study.Population: Four hundred forty-five women aged 40 years and over, predominantly low-income and with low literacy skills, who had not had a mammogram in the preceding year.Intervention: All interventions were chosen to motivate women to get a mammogram. Group 1 received a personal recommendation from one of the investigators. Group 2 received the recommendation plus an easy-to-read National Cancer Institute (NCI) brochure. Group 3 received the recommendation, the brochure, and a 12-minute interactive educational and motivational program, including a soap-opera-style video, developed in collaboration with women from the target population.Measurements and Main Results: Mammography utilization was determined at 6 months and 2 years after intervention. A significant increase (p = .05) in mammography utilization was observed after the intervention designed in collaboration with patients (29%) as compared with recommendation alone (21%) or recommendation with brochure (18%) at 6 months. However, at 2 years the difference favoring the custom-made intervention was no longer significant.Conclusions: At 6 months there was at least a 30% increase in the mammography utilization rate in the group receiving the intervention designed in collaboration with patients as compared with those receiving the recommendation alone or recommendation with brochure. Giving patients an easy-to-read NCI brochure and a personal recommendation was no more effective than giving them a recommendation alone, suggesting that simply providing women in a public hospital with a low-literacy-level, culturally appropriate brochure is not sufficient to increase screening mammography rates. In a multivariate analysis, the only significant predictor of mammography use at 6 months was the custom-made intervention. [ABSTRACT FROM AUTHOR]

Objective: To validate a model for the prediction of Clostridium difficile cytotoxin assay results, and to identify a subgroup of patients with a very low likelihood of C. difficile-associated disease in whom the yield of routine cytotoxin testing is low.Design: Prospective cohort study. Relevant clinical symptoms, signs, and antibiotic exposure were recorded before reporting of assay results. Each predictor was assigned a score based on regression coefficients, and patients were stratified according to their total score.Setting: Two urban, tertiary care, university hospitals.Patients: A total of 609 consecutive adult inpatients who received testing for C. difficile cytotoxin during a 3-month period in 1994.Measurements and Main Results: The prevalence of positive cytotoxin assays was 8% in the validation set, compared with 14% in the derivation set. Defining patients without both prior antibiotic use and at least one symptom predictor (significant diarrhea or abdominal pain) as a low-risk subgroup, the misclassification rate was 2.8% (5/177) for assay results; of the five misclassified cases patients, only one was judged to have C. difficile-associated disease. Use of this rule to identify low-risk patients could have potentially averted 29% of all cytotoxin assays.Conclusions: Patients without a history of antibiotic use and either significant diarrhea or abdominal pain are unlikely to have positive C. difficile cytotoxin assays and may not require cytotoxin testing.

Objective: To investigate the influence of hospital teaching status and service availability on rates of revascularization following myocardial infarction. Design: Retrospective cohort study based on province-wide hospital discharge abstracts. Setting: All acute care hospitals in Ontario, Canada's most populous province (9.7 million). Patients: Patients admitted to hospital between April 1, 1991, and September 30, 1991, with a principal diagnosis of acute myocardial infarction. Measurements: The odds of a patient's having been referred for revascularization (angioplasty or bypass surgery) within six months of a myocardial infarction were calculated based on the type of hospital to which he or she had initially presented, defined as 'teaching' or 'nonteaching' or as having or not having interventional facilities onsite (cardiac catheterization and/or revascularization). Odds ratios were adjusted for potential confounding variables, and for possible joint effects of teaching status and on-site interventional capabilities. Results: The patients were more likely to have had revascularization (OR 1.79 95% CI 1.47-2.14, p=0.0001) when they had been admitted to a teaching hospital, and independently were more likely to have been referred for revascularization (OR 1.34; 95% CI 1.09-1.66, p=0.0067) when they had been admitted to a hospital with on-site interventional facilities. There was no interaction between teaching status and service availability regarding referral for revascularization. Conclusion: Teaching status is an important determinant of revascularization following acute myocardial infarction and is independent of service availability, which also influences revascularization rates.

Objective: To explore the reasons for underutilization of beta blocker treatment after acute myocardial infarction.Design: A retrospective chart review.Setting: Two large community hospitals in Milwaukee, Wisconsin.Patients/participants: All subjects (n = 694) discharged alive from July 1, 1990, to June 30, 1991, who had a diagnosis of acute myocardial infarction were eligible. Of these, 250 had missing data, resulting in a final sample of 444.Results: Twenty-nine percent of the 444 patients were prescribed beta blocker therapy on discharge. Characteristics of the patients and their treatment associated with receipt of beta blocker therapy were identified with a logistic regression model. The adjusted odds ratios were 0.52 for female gender, 0.34 for no health insurance, 0.21 for chronic obstructive pulmonary disease, 0.46 for congestive heart failure, 0.28 for atrioventricular block, 1.86 for hypertension, 1.93 for chest pain during acute myocardial infarction, and 4.65 for prehospital beta blocker use. Prescription of beta blocker therapy was also influenced by receipt of other treatment modalities. The adjusted odds ratios were 0.23 for receipt of beta blocker therapy associated with myocardial revascularization, 0.18 for prescription on discharge of calcium channel blockers, and 0.22 for receipt of angiotensin-converting enzyme inhibitors.Conclusion: A minority of patients discharged after acute myocardial infarction receive beta blocker therapy, and women are only half as likely as men to receive it, after controlling for other factors. Though there are no data relating to whether calcium channel blockers or angiotensin-converting enzyme inhibitors lessen the protective effect of beta blocker therapy post-acute myocardial infarction, it would appear that these agents are frequently being used in lieu of beta blocker therapy for post-acute myocardial infarction patients.

Objective: To describe the practice pattern of a group of primary care providers in ordering echocardiography for healthy patients and to derive a decision aid to identify patients with systolic murmurs who have significant cardiac lesions.Design: Retrospective case review of clinical variables, including the demographic, historical, and physical examination features obtained from chart review of the physician evaluation prior to referral for echocardiography and the echocardiographic results, with both univariate and multivariate regression analyses used to identify variables predictive of positive echocardiographic outcomes and to derive a regression model.Setting: General internal medicine clinic in an urban major teaching hospital.Patients/participants: 169 patients between the ages of 18 and 55 years selected retrospectively from medical records.Measurements and Main Results: Symptoms and auscultatory findings were not predictive of positive echocardiographic outcomes among the patients referred for the test. For the patients who had systolic murmurs, a logistic regression model had three significant predictors of positive echocardiographic results: additional year of age (odds ratio: 1.08, 95% CI: 1.02-1.13; p = 0.007); male gender (odds ratio: 5.87, 95% CI: 1.99-17.3; p = 0.002); and murmur grade > or = 3 (odds ratio: 4.99, 95% CI: 1.27-19.6; p = 0.02). The receiver-operating characteristic (ROC) curve area for this model was 0.741. If women aged 35 years and less with murmur grades < or = 2 had not been referred, 47% of the echocardiographies could have been avoided while retaining a sensitivity of 90%.Conclusions: The study suggested that healthy patients with systolic murmurs are least likely to have positive echocardiographic results when they are young and female and have murmur grades < or = 2. More careful screening of this group might make unnecessary almost half of the echocardiographies yielding negative results ordered for healthy patients with systolic murmurs. [ABSTRACT FROM AUTHOR]

Background: Routine diagnostic endoscopy is commonly obtained for low-risk patients with acute upper gastrointestinal bleeding despite evidence from controlled trials that it does not improve patient outcome.Objective: To determine whether endoscopy is being overutilized for these patients or whether considerations not addressed in the trials could justify its widespread use.Methods: Twenty-five patients recovering from a recent hemorrhage and 22 primary care physicians used the analytic hierarchy process to perform an individualized analysis regarding the diagnostic management of acute upper gastrointestinal bleeding. The results were used to determine whether routine endoscopy was consistent with each subject's interpretation of relevant data and judgments regarding the relative importance of five management goals. The authors then compared the proportion of subjects in each group who preferred endoscopy over two non-endoscopy strategies (upper gastrointestinal series and no routine diagnostic test) with 85%, the current rate of endoscopy at the authors' hospital.Results: Endoscopy was preferred by 92% (97.5% CI: 70%-98%) of the patients and 55% (97.5% CI: 31%-77%) of the physicians. The patients ranked identifying the cause of bleeding the second most important management goal after avoiding a poor outcome from the acute bleeding episode.Conclusions: The current rate of diagnostic endoscopy is higher than would be expected based on physicians' preferences but quite consistent with patients' preferences. Patients regard knowledge of the bleeding site as important, even if this information will not affect management or prognosis. Attempts to assess the use of diagnostic endoscopy and other diagnostic tests should take both patient preferences and the pure value of diagnostic information into account. [ABSTRACT FROM AUTHOR]

Objective: To determine whether the protective effects of seat belt use on acute injury are followed by corresponding reductions in outpatient health care utilization. Design: Retrospective cohort analysis. Setting: Northern California Region Kaiser Health Plan hospitals and medical offices. Patients: All Kaiser Foundation Health Plan members injured in motor vehicle crashes in Santa Clara County during one year (total number of patients=246). Measurements and main results: 54% of the study participants had been wearing seat belts at the time of injury, and 46% had not been. The belted patients had fewer head injuries (30% vs 50%, p<0.05), better mean Injury Severity Scale scores (4.3 vs 7.4, p<0.05), and smaller mean hospital charges ($8,580 vs $16,209, p<0.05). However, the effects of injury did not end upon discharge from the trauma center; the patients averaged about eight outpatient visits during the subsequent year, a rate almost double their prior use. In contrast to inpatient measures of utilization, the patients who had been wearing seat belts at the time of injury had more outpatient visits during the year after injury than had their unbelted counterparts (9.0 vs 7.1, p<0.05). This discrepancy was not explained by differences in amounts of utilization during the year before injury, which were similar in the two groups (4.4 vs 4.8, p=NS). Overall, general internists provided the most follow-up care and accounted for the largest discrepancy in utilization between the belted and unbelted patients. Conclusions: Seat belt use does not result in lower utilization of follow-up outpatient services in the year following injury. However, the beneficial effects on acute care utilization more than offset the marginal effects on subsequent medical services utilization. [ABSTRACT FROM AUTHOR]
