Background: Little is known about the extent of ordering low-value services by., Purpose: To compare the rates of low-value back images ordered by primary care physicians (PCMDs) and primary care nurse practitioners (PCNPs)., Method: We used 2012 and 2013 Medicare Part B claims for all beneficiaries in 18 hospital referral ̱regions (HRRs) and a measure of low-value back imaging from Choosing Wisely. Models included random clinician effect and fixed effects for beneficiary age, disability, Elixhauser comorbidities, clinician sex, the emergency department setting, back pain visit volume, organization, and region (HRR)., Findings: PCNPs (N = 231) and PCMDs (N = 4,779) order low-value back images at similar rates (NP: all images: 26.5%; MRI/CT: 8.4%; MD: all images: 24.5%; MRI/CT: 7.7%), with no detectable significant difference when controlling for covariates., Discussion: PCNPs and PCMDs order low-value back images at an effectively similar rate., (Copyright © 2019 Elsevier Inc.

Objective: To evaluate the proof of concept of an innovative model of physical therapy Rehabilitation Enhancing Aging through Connected Health (REACH) and evaluated its feasibility and effect on physical function and health care utilization., Design: Quasi-experimental 12-month clinical trial., Setting: Two outpatient rehabilitation centers., Participants: Community-dwelling older primary care patients with a treatment arm undergoing the intervention (n=75; mean age=77±5.9y; 54% women) and propensity matched controls derived from a longitudinal cohort study (n=430; mean age=71±7.0y; 68% women) using identical recruitment criteria (N=505)., Intervention: Combined outpatient and home PT augmented with a commercially available app and computer tablet., Measurements: Primary outcomes included a feasibility questionnaire, exercise adherence, self-reported function, and the Short Physical Performance Battery (SPPB). Secondary outcomes included the rates of emergency department (ED) visits and hospitalizations., Results: Among REACH participants, we observed a 9% dropout rate. After accounting for dropouts, with propensity matching, n=68 treatments and n=100 controls were analyzed. Over the 12-month study duration, 85% of participants adhered to the exercise program an average of 2 times a week and evaluated the treatment experience favorably. In comparison to controls, after 1 year of treatment and within multivariable regression models, REACH participants did not manifest a significant difference in patient reported function (group x time effect 1.67 units, P=.10) but did manifest significant differences in SPPB (group x time effect 0.69 units, P=.03) and gait speed (group x time effect .08m/s, P=.02). In comparison to controls, after 1 year, the rate of ED visits (group x time treatment rate=0.27, P<.004) were significantly reduced, but a significant reduction in hospitalizations was not observed., Conclusion: The REACH intervention is feasible and has proof of concept in preventing functional decline and favorably affecting health care utilization. Evaluation on a larger scale is warranted., (Published by Elsevier Inc.)

Context: State scope of practice (SoP) laws impose significant restrictions on the services that a nurse practitioner (NP) may provide in some states, yet evidence about SoP limitations on the quality of primary care is very limited. Method: This study uses six different classifications of state regulations and bivariate and multivariate analyses to compare beneficiaries attributed to primary care nurse practitioners and primary care physicians in 2013 testing two hypotheses: (1) chronic disease management, cancer screening, preventable hospitalizations, and adverse outcomes of care provided by primary care nurse practitioners are better in reduced and restricted practice states compared to states without restrictions and (2) by decreasing access to care, SoP restrictions negatively affect the quality of primary care. Findings: Results show a lack of consistent association between quality of primary care provided by NPs and state SoP restrictions. Conclusion: State regulations restricting NP SoP do not improve the quality of care.

Background: Primary care providers are at the center of the opioid epidemic. Whether nurse practitioners (NPs) have different opioid-prescribing outcomes from physicians is not known., Objective: To examine opioid-prescribing outcomes of Medicare beneficiaries receiving care from NPs and physicians in primary care., Research Design: We used Medicare data from 2009 to 2013 and a propensity score-weighted analysis., Subjects: Beneficiaries residing in states in which NPs are able to prescribe controlled substances without physician oversight and who did not have a cancer diagnosis, hospice care, or end-stage renal disease., Measures: First, we measured whether beneficiaries received any opioid prescription. Second, for beneficiaries who received opioids, we measured acute (<90 d supply) and chronic (≥90 d supply) use at baseline (2009-2010) and follow-up (2012-2013). Third, we measured potential misuse of opioid prescribing using a daily morphine milligram equivalent dose of >100 mg, overlapping prescriptions of opioids >7 days, and overlapping prescriptions of opioids with benzodiazepines >7 days., Results: Beneficiaries managed by NPs were less likely to receive an opioid [odds ratio (OR), 0.87; P<0.001], were less likely to be acute users at baseline (OR, 0.84; P<0.001), and were more likely to receive a high daily opioid dose of morphine milligram equivalent >100 mg compared with physician-managed beneficiaries (OR, 1.11; P=0.048)., Conclusions: Findings suggest educational programs and clinical guidelines may require approaches tailored to different providers. Future research should examine the contributing factors of these patterns to ensure high-quality pain management and guide policy makers on NP-controlled substance-prescribing regulations.

Objective: To compare medication adherence, cost, and utilization in Medicare beneficiaries attributed to nurse practitioners (NP) and primary care physicians (PCP)., Data: Medicare Part A, B, and D claims and beneficiary summary file data, years 2009-2013., Study Design: We used propensity score-weighted analyses combined with logistic regression and generalized estimating equations to test differences in good medication adherence (proportion of days covered (PDC >0.8); office-based and specialty care costs; and ER visits., Data Extraction: Beneficiaries with prescription claims for anti-diabetics, renin-angiotensin system antagonists (RASA), or statins., Principal Findings: There were no differences in good medication adherence (PDC >0.8) between NP and PCP attributed beneficiaries taking anti-diabetics or RASA. Beneficiaries taking statins had a slightly higher probability of good adherence when attributed to PCPs (74.6% vs 75.5%; P < 0.05). NP attributed beneficiaries had lower office-based and specialty care costs and were less likely to experience an ER visit across all three medication cohorts (P < 0.01)., Conclusions: Examining the impact of NP and PCP provided care on outcomes beyond the primary care setting is important to the Medicare program in general but will also help practices seeking to meet benchmarks under alternative payment models that incentivize higher quality and lower costs., (© Health Research and Educational Trust.)

Background: National guidelines require programmes use subjective assessments of social support when determining transplant suitability, despite limited evidence linking it to outcomes. We examined how transplant providers weigh the importance of social support for kidney transplantation compared with other factors, and variation by clinical role and personal beliefs., Methods: The National survey of the American Society of Transplant Surgeons and the Society of Transplant Social Work in 2016. Using a discrete choice approach, respondents compared two hypothetical patient profiles and selected one for transplantation. Conditional logistic regression estimated the relative importance of each factor; results were stratified by clinical role (psychosocial vs medical/surgical providers) and beliefs (outcomes vs equity)., Results: Five hundred and eighy-four transplant providers completed the survey. Social support was the second most influential factor among transplant providers. Providers were most likely to choose a candidate who had social support (OR=1.68, 95% CI 1.50 to 1.86), always adhered to a medical regimen (OR=1.64, 95% CI 1.46 to 1.88), and had a 15 years life expectancy with transplant (OR=1.61, 95% CI 1.42 to 1.85). Psychosocial providers were more influenced by adherence and quality of life compared with medical/surgical providers, who were more influenced by candidates' life expectancy with transplant (p<0.05). For providers concerned with avoiding organ waste, social support was the most influential factor, while it was the least influential for clinicians concerned with fairness (p<0.05)., Conclusions: Social support is highly influential in listing decisions and may exacerbate transplant disparities. Providers' beliefs and reliance on social support in determining suitability vary considerably, raising concerns about transparency and justice., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Objective: To examine differences in the quality of care provided by primary care nurse practitioners (PCNPs), primary care physicians (PCMDs), or both clinicians., Data Sources: Medicare part A and part B claims during 2012-2013., Study Design: Retrospective cohort design using standard risk-adjustment methodologies and propensity score weighting assessing 16 claims-based quality measures grouped into 4 domains of primary care: chronic disease management, preventable hospitalizations, adverse outcomes, and cancer screening., Extraction Methods: Continuously enrolled aged, disabled, and dual eligible beneficiaries who received at least 25% of their primary care services from a random sample of PCMDs, PCNPs, or both clinicians., Principal Findings: Beneficiaries attributed to PCNPs had lower hospital admissions, readmissions, inappropriate emergency department use, and low-value imaging for low back pain. Beneficiaries attributed to PCMDs were more likely than those attributed to PCNPs to receive chronic disease management and cancer screenings. Quality of care for beneficiaries jointly attributed to both clinicians generally scored in the middle of the PCNP and PCMD attributed beneficiaries with the exception of cancer screening., Conclusions: The quality of primary care varies by clinician type, with different strengths for PCNPs and PCMDs. These comparative advantages should be considered when determining how to organize primary care to Medicare beneficiaries.

Objective: To examine whether there are differences in inpatient rehabilitation facilities' (IRFs') all-cause 30-day postdischarge hospital readmission rates vary by organizational characteristics and geographic regions., Design: Observational study., Setting: IRFs., Participants: Medicare fee-for-service beneficiaries discharged from all IRFs nationally in 2013 and 2014 (N = 1166 IRFs)., Interventions: Not applicable., Main Outcome Measures: We applied specifications for an existing quality measure adopted by Centers for Medicare & Medicaid Services for public reporting that assesses all-cause unplanned hospital readmission measure for 30 days postdischarge from inpatient rehabilitation. We estimated facility-level observed and risk-standardized readmission rates and then examined variation by several organizational characteristics (facility type, profit status, teaching status, proportion of low-income patients, size) and geographic factors (rural/urban, census division, state)., Results: IRFs' mean risk-standardized hospital readmission rate was 13.00%±0.77%. After controlling for organizational characteristics and practice patterns, we found substantial variation in IRFs' readmission rates: for-profit IRFs had significantly higher readmission rates than did not-for-profit IRFs (P<.001). We also found geographic variation: IRFs in the South Atlantic and South Central census regions had the highest hospital readmission rates than did IRFs in New England that had the lowest rates., Conclusions: Our findings point to variation in quality of care as measured by risk-standardized hospital readmission rates after IRF discharge. Thus, monitoring of readmission outcomes is important to encourage quality improvement in discharge care planning, care transitions, and follow-up., (Copyright © 2017 American Congress of Rehabilitation Medicine.

Background: Studies suggest nurse practitioners are heavily represented among primary care providers for vulnerable Medicare beneficiaries., Purpose: The purpose of this study was to compare quality indicators among three groups of vulnerable beneficiaries managed by MDs and nurse practitioners (NPs)., Methods: The methods include retrospective cohort design examining 2012 and 2013 Medicare claims for three beneficiary groups: (a) initially qualified for the program due to disability, (b) dually eligible for Medicare and Medicaid, and (c) both disabled and dually eligible. Validated quality indicators in four domains were analyzed., Discussion: Gaps in outcomes suggest better performance for primary care nurse practitioners (PCNPs) in preventable hospitalizations and adverse outcomes. Outcome gaps suggesting better performance for primary care physicians in chronic disease management were diminished for beneficiaries who were both disabled and dually eligible suggesting improved performance for PCNPs within this subpopulation., Conclusion: These findings add new evidence indicating the quality of primary care provided to vulnerable Medicare beneficiaries by PCNPs is generally consistent with clinical guidelines and the less intensive use of costly health care services., (Copyright © 2017 Elsevier Inc.

Background: Mobility limitations among older adults increase the risk for disability and healthcare utilization. Rehabilitative care is identified as the most efficacious treatment for maintaining physical function. However, there is insufficient evidence identifying a healthcare model that targets prevention of mobility decline among older adults. The objective of this study is to evaluate the preliminary effectiveness of a physical therapy program, augmented with mobile tele-health technology, on mobility function and healthcare utilization among older adults., Methods: This is a quasi-experimental 12-month clinical trial conducted within a metropolitan-based healthcare system in the northeastern United States. It is in parallel with an existing longitudinal cohort study evaluating mobility decline among community-dwelling older adult primary care patients over one year. Seventy-five older adults (≥ 65-95 years) are being recruited using identical inclusion/exclusion criteria to the cohort study. Three aims will be evaluated: the effect of our program on 1) physical function, 2) healthcare utilization, and 3) healthcare costs. Changes in patient-reported function over 1 year in those receiving the intervention (aim 1) will be compared to propensity score matched controls (N = 150) from the cohort study. For aims 2 and 3, propensity scores, derived from logistic regression model that includes demographic and diagnostic information available through claims and enrollment information, will be used to match treatment and control patients in a ratio of 1:2 or 1:3 from a Medicare Claims Registry derived from the same geographic region. The intervention consists of a one-year physical therapy program that is divided between a combination of outpatient and home visits (6-10 total visits) and is augmented on a computerized tablet using of a commercially available application to deliver a progressive home-based exercise program emphasizing lower-extremity function and a walking program., Discussion: Incorporating mobile health into current healthcare models of rehabilitative care has the potential to decrease hospital visits and provide a longer duration of care. If the hypotheses are supported and demonstrate improved mobility and reduced healthcare utilization, this innovative care model would be applicable for optimizing the maintenance of functional independence among community-dwelling older adults., Trial Registration: ClinicalTrial.gov Identifier: NCT02580409 (Date of registration October 14, 2015).

Introduction: A core challenge of a multidisciplinary and multi-organizational translational research enterprise such as a Clinical and Translational Research Award (CTSA) is coordinating and integrating the work of individuals, workgroups, and organizations accustomed to working independently and autonomously. Tufts Clinical and Translational Science Institute (CTSI) undertook and studied a multifacted intervention to address this challenge and to create a culture of systems thinking, process awareness, responsive to others' needs, and shared decision-making., Intervention: The intervention, based on relational coordination, included 1) relational interventions, in three staff retreats and a diagnostic survey to provide feedback on the current quality of relational coordination, and 2) structural interventions, in the launching of five new cross-functional teams with regular meeting structures., Methods: A mixed-methods evaluation yielded quantitative data via two types of team surveys and qualitative data via interviews and meeting observations., Results: The findings suggest that interventions to improve relational coordination are feasible for CTSAs, including good fidelity to the model and staff/physician engagement. Survey and interview data suggest model improvements in coordination and alignment. Further research about their optimal design is warranted., (© The Association for Clinical and Translational Science 2017.)

To improve health outcomes among transgender women of color living with HIV, the Health Resources and Services Administration's Special Programs of National Significance program funded the Enhancing Engagement and Retention in Quality HIV Care for Transgender Women of Color Initiative in 2012. Nine demonstration projects in four US urban areas implemented innovative, theory-based interventions specifically targeting transgender women of color in their jurisdictions. An evaluation and technical assistance center was funded to evaluate the outcomes of the access to care interventions, and these findings will yield best practices and lessons learned to improve the care and treatment of transgender women of color living with HIV infection.

Objective: This study is designed to assess the cost of services provided to Medicare beneficiaries by nurse practitioners (NPs) billing under their own National Provider Identification number as compared to primary care physicians (PCMDs)., Data Source: Medicare Part A (inpatient) and Part B (office visit) claims for 2009-2010., Study Design: Retrospective cohort design using propensity score weighted regression., Data Extraction Methods: Beneficiaries cared for by a random sample of NPs and primary care physicians., Principal Findings: After adjusting for demographic characteristics, geography, comorbidities, and the propensity to see an NP, Medicare evaluation and management payments for beneficiaries assigned to an NP were $207, or 29 percent, less than PCMD assigned beneficiaries. The same pattern was observed for inpatient and total office visit paid amounts, with 11 and 18 percent less for NP assigned beneficiaries, respectively. Results are similar for the work component of relative value units as well., Conclusions: This study provides new evidence of the lower cost of care for beneficiaries managed by NPs, as compared to those managed by PCMDs across inpatient and office-based settings. Results suggest that increasing access to NP primary care will not increase costs for the Medicare program and may be cost saving., (© Health Research and Educational Trust.)

Background: Little is known about the geographic distribution of the overall primary care workforce that includes both physician and nonphysician clinicians--particularly in areas with restrictive nurse practitioner scope-of-practice laws and where there are relatively large numbers of uninsured., Objective: We investigated whether geographic accessibility to primary care clinicians (PCCs) differed across urban and rural areas and across states with more or less restrictive scope-of-practice laws., Research Design: An observational study., Subjects: 2013 Area Health Resource File (AHRF) and US Census Bureau county travel data., Measures: The measures included percentage of the population in low-accessibility, medium-accessibility, and high-accessibility areas; number of geographically accessible primary care physicians (PCMDs), nurse practitioners (PCNPs), and physician assistants (PCPAs) per 100,000 population; and number of uninsured per PCC., Results: We found divergent patterns in the geographic accessibility of PCCs. PCMDs constituted the largest share of the workforce across all settings, but were relatively more concentrated within urban areas. Accessibility to nonphysicians was highest in rural areas: there were more accessible PCNPs per 100,000 population in rural areas of restricted scope-of-practice states (21.4) than in urban areas of full practice states (13.9). Despite having more accessible nonphysician clinicians, rural areas had the largest number of uninsured per PCC in 2012. While less restrictive scope-of-practice states had up to 40% more PCNPs in some areas, we found little evidence of differences in the share of the overall population in low-accessibility areas across scope-of-practice categorizations., Conclusions: Removing restrictive scope-of-practice laws may expand the overall capacity of the primary care workforce, but only modestly in the short run. Additional efforts are needed that recognize the locational tendencies of physicians and nonphysicains.

Background: To mitigate shortages of primary care physicians and ensure access to health care services for a growing number of Medicare beneficiaries, some policy makers have recommended expanding the supply and roles of nurse practitioners (NPs). Little is known about the number of NPs billing Medicare or their practice patterns., Purpose: This study examines the geographic distribution and county characteristics of NPs billing Medicare, compares the types and quantities of primary care services provided to Medicare beneficiaries by NPs and primary care physicians, and analyzes the characteristics of beneficiaries receiving primary care from each type of clinician., Methods: We performed a cross-sectional analysis of 2008 Medicare administrative data from 959,848 aged and/or disabled beneficiaries continuously enrolled in fee-for-service Medicare during the study period. Outcome measures included geographic distribution of NPs measured by the rate of NPs per 1,000 Medicare beneficiaries by state, average utilization, and patient characteristics., Discussion: States with the highest rate of NPs billing were rural. Over 80% of the payments received by both NPs and primary care physicians were for evaluation and management services. Beneficiaries assigned to an NP were more likely to be female, to be dually eligible for Medicare and Medicaid, and to have qualified for Medicare because of a disability. NPs with assigned beneficiaries were significantly more likely than similar primary care physicians to practice in federally designated primary care shortage areas., Conclusions: Approximately 45,000 NPs were providing services to beneficiaries and billing under their own provider numbers in 2008. Aspects of NP practice patterns were different from primary care physicians, and NPs appeared more likely to provide services to disadvantaged Medicare beneficiaries., (Copyright © 2013 Elsevier Inc.

A randomized trial of substance abuse treatment programs tested whether "enhanced profiles," consisting of feedback and coaching about performance indicators, improved the performance of residential, methadone, and detoxification programs. These enhanced profiles were reviewed during quarterly on-site visits between October 2005 and July 2007. The performance indicators were the percentage of clients completing referrals to a lower level of care, and the percentage of clients admitted to a higher level of care within 30 days of discharge. Control programs received only "basic profiles," consisting of emailed quarterly printouts of these performance indicators. Effectiveness was evaluated using hierarchical linear models with client-level information nested within agencies and regions of the state. Treatment programs receiving enhanced profiles (n = 74) did not perform significantly differently from those receiving only basic profiles (n = 29) on either performance measure. To improve performance, interventions with greater scope and incentives may be needed.

Little is known about the relationship of demographic, health, and psychosocial factors with health services utilization over time among low-income female heads of household. In a case-control study conducted between 1991 and 1997, 273 homeless and low-income housed mothers living in Worcester, Massachusetts were interviewed at baseline and at a two-year follow-up. The use of outpatient and emergency department care in this study sample was examined. High usage patterns were found at baseline. At the two-year follow-up, poor health status, non-White race, and fewer supportive relationships were significantly associated with frequent emergency department visits. Women with higher rates of ongoing outpatient medical care visits were more likely to have fewer social supports and more bodily pain than women with lower rates of ambulatory care usage. Mental health and victimization were not associated with service use patterns. In order to address poor women's needs in a more effective and potentially less costly way, health programs must understand their need for social support and culturally responsive services.

As people with HIV live longer and healthier lives, ongoing prevention with positive individuals has become a new focus of care. Effective prevention with positives interventions are emerging and new interventions continue to be developed. This article discusses the development and evaluation of the prevention for positives intervention developed for a large AIDS service organization in Chicago. The intervention consists of case manager based HIV prevention education and support within residential and community settings. The article describes the intervention and presents the methods and findings of the program evaluation. The multidimensional evaluation includes formative and process evaluation elements as well as qualitative and quantitative measures (N = 94). The article concludes with a discussion of the challenges and opportunities associated with integrating prevention into care.

This evaluation of substance abuse and mental health treatment services in Arizona discusses and illustrates the use of data already collected by the State to manage and monitor the public behavioral health sector. The authors utilize a framework that focuses on rate-setting and financial incentives; provider profiling and education; and monitoring of data quality and system-wide performance. Information and analysis can contribute to key management activities and forces that guide behavior in the system toward optimal system performance. Using data from 33,208 Medicaid-covered and uninsured adults, service mix varied substantially by region; for example, spending on residential care ranged from 0% to 40% for substance abuse treatment clients. By focusing on a smaller group of client with functional assessments, it also appears that regional spending levels varied considerably, for reasons not explained by client demographics or clinical measures. Finally, longitudinal data show that the regional managed care organizations are moving in different directions with regard to client mix and spending priorities. All of this variation suggests that there may be considerable latitude to guide and improve system-wide performance.

Objectives: To identify childhood antecedents for lifetime post-traumatic stress disorder (PTSD) and to determine how this diagnosis relates to health and service use among extremely poor women., Methods: We conducted a secondary data analysis of 425 women in the Worcester Family Research Project, a case-control longitudinal study of 220 sheltered homeless and 216 extremely poor housed (never homeless) women in Worcester, Massachusetts., Results: We found that extremely poor women with lifetime PTSD were more likely to have grown up in family environments of violence, threat, and anger than those without PTSD. The strongest risk factor for PTSD was childhood sexual abuse with threat. Low-income women with lifetime PTSD had more bodily pain, even when controlling for other health and demographic factors. Women with PTSD experienced more chronic health conditions and had more problematic relationships with their health care providers and perceived more barriers to care., Conclusion: Many low-income women have difficulty using medical care appropriately because of childhood histories of physical and sexual abuse, the subsequent development of post-trauma responses, and structural barriers to care. Given these factors, it is critical that health care clinicians routinely screen for histories of violence and PTSD and develop treatment plans that ensure safety, link current symptoms with prior experiences, and provide support as necessary. A team approach coordinated by a case manager may be the best strategy. Without routine screening for PTSD and sensitive treatment, many extremely poor women will receive compromised health care and may even be retraumatized.

Objectives/hypothesis: To study the effects of bone involvement in experimentally induced sinusitis and the effect of involved bone on the overlying mucosa., Study Design: Animal study., Methods: Sinusitis was induced unilaterally with Pseudomonas aeruginosa in the maxillary sinus of 19 New Zealand white rabbits. At 6 weeks, the pathogenic organism was confirmed by culture, and a segment of the bone from the medial wall of the sinus implanted in a submucosal pocket in the opposite sinus. The rabbits were killed at predetermined time intervals up to 13 weeks from sinusitis induction, and en bloc sinus sections were decalcified and stained., Results: The implanted bone reabsorbed partially or totally in all specimens. However, the study revealed clear histological evidence of bone involvement adjacent to the infected sinuses and the bony changes extended to the noninfected side in all specimens. The histological findings were identical to those seen in chronic osteomyelitis., Conclusions: This study demonstrates the ability for pseudomonal sinusitis, at least in the presence of surgical intervention, to involve bone at a distance from the site of primary infection in the absence of intervening mucosal disease. If confirmed with additional organisms and models, these findings have significant implications for the therapeutic management of chronic sinus disease.

Objectives: The purpose of this study was to determine long-term outcome in adults with congenitally corrected transposition of the great arteries (CCTGA), with particular emphasis on systemic ventricular dysfunction and congestive heart failure (CHF)., Background: Patients with CCTGA have the anatomical right ventricle as their systemic pumping chamber, with ventricular dysfunction and CHF being relatively common in older adults., Methods: Retrospective analysis of records of 182 patients from 19 institutions were reviewed to determine current status and possible risk factors for systemic ventricular dysfunction and CHF. Factors considered included age, gender, associated cardiac defects, operative history, heart block, arrhythmias and tricuspid (i.e., systemic atrioventricular) regurgitation (TR)., Results: Both CHF and systemic ventricular dysfunction were common in groups with or without associated cardiac lesions. By age 45, 67% of patients with associated lesions had CHF, and 25% of patients without associated lesions had this complication. The rates of systemic ventricular dysfunction and CHF were higher with increasing age, the presence of significant associated cardiac lesions, history of arrhythmia, pacemaker implantation, prior surgery of any type, and particularly with tricuspid valvuloplasty or replacement. Aortic regurgitation (a previously unreported problem) was also relatively common in this patient population., Conclusions: Patients with CCTGA are increasingly subject to CHF with advancing age; this complication is extremely common by the fourth and fifth decades. Tricuspid (systemic atrioventricular) valvular regurgitation is strongly associated with RV (anatomical right ventricle connected to aorta in CCTGA patients; systemic ventricle in CCTGA) dysfunction and CHF; whether it is causative or a secondary complication remains speculative.

Background: Knowledge of human immunodeficiency virus (HIV) and its risk behaviors have not been systematically studied in homeless mothers. The identification of the factors associated with HIV-risk practices will guide interventions for low-income housed and homeless women., Methods: We interviewed 220 homeless and 216 low-income housed mothers living in Worcester, Massachusetts, to gather information on demographic, psychosocial , and HIV-risk practice characteristics. We used standardized instruments and questions drawn from national surveys. The primary study outcome was high HIV-risk behavior., Results: Although homeless mothers were more likely than low-income housed mothers to report first sexual contact at an early age, multiple partners during the last 6 months, and a history of intravenous drug use, homelessness was not associated with high HIV-risk practices. Both homeless and low-income housed mothers demonstrated misconceptions about HIV transmission through casual contact. Among high-risk women, approximately 75% perceived themselves as having low or no risk for contracting HIV. A history of childhood victimization, adult partner violence, or both placed women at a significantly increased likelihood of high HIV-risk practices. African American race, knowledge about HIV, and self-perception of risk were also significantly associated with high-risk practices., Conclusions: Homeless mothers are a subgroup of poor women at high risk for HIV and should be targeted for preventive interventions. In addition, there are potentially modifiable factors associated with HIV-risk practices in both low-income housed and homeless mothers that should be directly addressed.

Objectives: Morbidity and mortality patterns were characterized in adults with the Eisenmenger syndrome when two ventricles with a ventricular septal defect (VSD) joined two great arteries or one great artery, or when one ventricle joined two great arteries., Background: Although afterload in these disorders differs, clinical differences have not been defined., Methods: Seventy-seven patients were studied. Group A comprised 47 patients with VSD, aged 23 to 69 years (mean 39.5+/-10.2), follow-up 5 to 18 years (mean 7.2+/-4.9); group B, 14 patients with truncus arteriosus, aged 27 to 50 years (mean 33.7+/-7.3), follow-up 6 to 18 years (mean 7.7+/-5.1), and group C, 16 patients with univentricular heart, aged 18 to 44 years (mean 30.6+/-8.4), follow-up 5 to 15 years (mean 4.4+/-4.2). Echocardiography established the diagnoses and anatomic and hemodynamic features. Data were compiled on tachyarrhythmias, pregnancy, infective endocarditis, noncardiac surgery and the multisystem disorders of cyanotic adults., Results: Thirty-five percent of the patients died. Sixty-three percent of deaths were sudden, and resulted from intrapulmonary hemorrhage, rupture of either the pulmonary trunk, ascending aorta or a bronchial artery, or vasospastic cerebral infarction, or the cause was unestablished. There were no documented tachyarrhythmic sudden deaths., Conclusions: Medical management of coexisting cardiac disease, multisystem systemic disorders, noncardiac surgery and pregnancy has reduced morbidity. Increased longevity exposed patients to proximal pulmonary arterial aneurysms, thromboses and calcification; to truncal valve stenosis and regurgitation; to semilunar and atrioventricular valve regurgitation, and to major risks of nontachyarrhythmic sudden death.

This study investigated individual and neighborhood factors associated with late entry into prenatal care. Data from 220,694 New York City birth certificates were linked with data from the 1990 census and other secondary sources to determine the effect of women's individual characteristics and their neighborhood context on timing of prenatal care entry. Results indicate that 15 percent of New York City's pregnant women entered prenatal care late and that residence in a distressed urban neighborhood significantly increased the risk of late initiation, even in a model controlling for individual risk factors. Implications for social workers include the importance of outreach and case management for pregnant women, the value of health and social policies targeting distressed urban neighborhoods, and the need to ensure that Medicaid managed care implementation fosters use of prenatal care. The findings also underscore the importance of continuing to strive for a policy that ensures lifelong universal access to health care.

Objective: This study compared the prevalence of DSM-III-R disorders among homeless and low-income housed mothers with the prevalence of these disorders among all women in the National Comorbidity Survey., Method: The authors used an unmatched case-control design for assessing 220 homeless and 216 housed mothers receiving public assistance., Results: Homeless and housed mothers had similar rates of psychiatric and substance use disorders. Both groups had higher lifetime and current rates of major depression and substance abuse than did all women in the National Comorbidity Survey. Both groups also had high rates of posttraumatic stress disorder and two or more lifetime conditions., Conclusions: The prevalence of trauma-related disorders among poor women was higher than that among women in the general population. Programs and policies designed for low-income mothers must respond to the high prevalence of DSM-III-R disorders.

Objective: Previous studies of homeless children have described more health problems and service use than in housed children, but failed to control for potential confounding factors that may differ between these children. This observational study examines the relationship of homelessness and other determinants to health status and service use patterns in 627 homeless and low-income housed children., Methods: Case-control study of 293 homeless and 334 low-income housed children aged 3 months to 17 years and their mothers conducted in Worcester, Massachusetts. Information was collected about mothers' housing history, income, education, emotional distress, and victimization history. Standardized instruments were administered to assess children's health. Health service use questions were adapted from national surveys. Main outcome measures included health status, acute illness morbidity, emergency department and outpatient medical visits. Multivariable regression analyses were used to examine the association of family and environmental determinants, including homelessness, with health status and service use outcomes., Results: Mothers of homeless children were more likely to report their children as being in fair or poor health compared with their housed counterparts. Homeless children were reported to experience a higher number of acute illness symptoms, including fever, ear infection, diarrhea, and asthma. Emergency department and outpatient medical visits were higher among the homeless group. After controlling for potential explanatory factors, homeless children remained more likely to experience fair or poor health status (adjusted odds ratio [OR] = 2.83; 95% confidence interval [CI], 1.16, 4.87), and a higher frequency of outpatient (OR = 1.71; 95% CI, 1.18, 2.48) and emergency department visits (OR = 1.21; 95% CI, 0.83, 1.74). Mothers' emotional distress was independently associated with acute illness symptoms and frequent use of outpatient and emergency department settings., Conclusions: Homelessness is an independent predictor of poor health status and high service use among children. The present findings highlight the importance of preventive interventions and efforts to increase access to primary care among homeless children.

Background: A major predisposing cause of infective endocarditis is a susceptible cardiac substrate characterized by high-velocity turbulent flow. However, the risk incurred by high-pressure, high-velocity regurgitation across inherently normal pulmonary and tricuspid valves has not hitherto been examined., Methods and Results: This study focused on 186 adult patients with congenital heart disease who had pulmonary vascular disease and inherently normal right-sided pulmonary and tricuspid valves. The observation period was approximately 1646 patient-years. Exclusion criteria were coexisting lesions that might have served as independent risk substrates for infective endocarditis. High-velocity turbulent pulmonary and tricuspid regurgitation were identified and quantified by color flow imaging and continuous wave Doppler echocardiography. Diagnoses of infective endocarditis were based on established clinical and laboratory criteria. Tricuspid regurgitation was moderate to severe in 80 patients and mild or absent in 106 patients. Pulmonary regurgitation was moderate to severe in 84 patients and mild or absent in 102 patients. With the exception of a single habitual intravenous drug abuser, no patient, irrespective of the degree of high-velocity turbulent pulmonary or tricuspid regurgitation, had infective endocarditis., Conclusions: High-velocity turbulent flow across inherently normal pulmonary and tricuspid valves rendered incompetent by pulmonary hypertension may represent a relatively low-risk or no-risk substrate for infective endocarditis.

Objective: To compare the health characteristics and service utilization patterns of homeless women and low-income housed women who are heads of household., Design: Case-control study., Setting: Community of Worcester, Massachusetts., Participants: A sample of 220 homeless mothers and 216 low-income housed mothers receiving welfare., Measurements and Main Results: Outcome measures included health status, chronic conditions, adverse lifestyle practices, outpatient and emergency department use and hospitalization rates, and use of preventive screening measures. Both homeless mothers and housed mothers demonstrated low levels of physical and role functioning and high levels of bodily pain. Prevalence rates of asthma, anemia, and ulcer disease were high in both groups. More than half of both groups were current smokers. Compared with the housed mothers, homeless mothers reported more HIV risk behaviors. Although 90% of the homeless mothers had been screened for cervical cancer, almost one third had not been screened for tuberculosis. After controlling for potential confounding factors, the homeless mothers, compared with the housed mothers, had more frequent emergency department visits in the past year (adjusted mean, homeless vs housed, 1.41 vs .95, p = .10) and were significantly more likely to be hospitalized in the past year (adjusted odds ratio 2.22; 95% confidence interval 1.13, 4.38)., Conclusions: Both homeless mothers and low-income housed mothers had lower health status, more chronic health problems, and higher smoking rates than the general population. High rates of hospitalization, emergency department visits, and more risk behaviors among homeless mothers suggest that they are at even greater risk of adverse health outcomes. Efforts to address gaps in access to primary care and to integrate psychosocial supports with health care delivery may improve health outcomes for homeless mothers and reduce use of costly medical care services.

Objectives: To describe the characteristics of homeless and low-income preschool-aged children, and to identify family and environmental determinants of their behavior., Methods: An unmatched case-control design was used to recruit a sample of sheltered homeless families and a comparison group of low-income housed families who were never homeless in Worcester, Massachusetts. Seventy-seven sheltered homeless and 90 low-income housed mothers with preschool-age children were assessed using a comprehensive interview protocol. Information about mothers' housing, income, service use, par-enting practices, and children's father was obtained. Data about children's background, health, and life events were included. Standardized instruments were administered to assess mothers' mental health and their children's behavior. Comparisons of homeless and low-income housed families were used to describe the sample of 167 preschoolers. Multiple linear regression was used to examine the association of various stressors, such as homelessness, and family factors with their behavior., Results: Although homeless preschoolers were significantly more likely to have experienced stressful life events, undergone a care and protection investigation, and been placed in foster care when compared with low income preschoolers, differences in adverse behaviors were minimal. Although homeless children scored higher than housed children on the internalizing, externalizing, and total problem score on the Child Behavior Checklist (CBCL) (52.5 vs 49.9, 54.8 vs 51.2, and 54.4 vs 51.1, respectively), approximately equal numbers of children from both groups scored in the clinical range. With regard to determinants of behavior, mothers' emotional status was one of the strongest independent predictors of negative behavioral outcomes on both subscales. Foster care placement and death of a child's friend were predictors of adverse internalizing behavioral outcomes on the CBCL. After controlling for housing status, parenting practices, child's age, child's history of physical abuse, and specific life stressors predicted adverse externalizing behavioral outcomes. For both subscales, housing status and behavior were only marginally associated in the multivariate model., Conclusions: Both homeless and low-income children experienced significant adversity in their lives, with homeless preschool children facing more stress. However, differences in behavior as measured by the CBCL were minimal. Mothers' emotional status, in addition to various stressors, strongly predict children's negative outcomes for both CBCL subscales. These findings emphasize the importance of preventive family-oriented interventions that address the needs of preschoolers and their mothers.

This paper considers policy and programmatic consequences of shifting measurement of prenatal care utilization from the Kessner Index (KI) to the Adequacy of Prenatal Care Utilization Index (APNCUI). In gauging the adequacy of prenatal care utilization, the KI considers the timing of prenatal care initiation and the number of prenatal visits. The APNCUI also considers both timing of initiation and number of visits, but the approach taken to conceptualizing and measuring these two aspects of prenatal care utilization is more refined. We used birth certificates to calculate the KI and the APNGUI for 217,183 New York City (NYC) births in 1991-1992. We used cross-tabulations and bivariate odds ratios to compare the classifications resulting from the respective indexes. The APNCUI detected some important dimensions of the problem of inadequate prenatal care use that are not evident when using the KI. The proportion of births with inadequate use increases from 18% with the KI to 35% with the APNGUI. Groups of women at elevated risk for inadequate use are the same, but the KI understates significantly the risk for Hispanic women, teens, women who are less well educated, and those on WIC and Medicaid. The APNGUI yields a fuller picture of the degree to which some urban women are at risk for inadequate prenatal care use. Use of the APNGUI in quality assurance, monitoring, and research is recommended.

Background: A retrospective clinical study was performed to document the course of adult patients undergoing the Fontan procedure., Methods: Between 1982 and 1994, 21 adults aged 18 to 40 years (mean age, 27 +/- 7 years) underwent a Fontan procedure. Anatomic diagnosis was tricuspid atresia in 9, double-inlet left ventricle in 4, and various single ventricles in 8. Four underwent a right atria-right ventricle connection, 13 had a right atria-pulmonary artery connection, and 4 had a lateral-tunnel Fontan. Three of these 4 had a snare-adjustable atrial septal defect. Preoperative risk factors assessed were left ventricular end-diastolic pressure greater than 10 mm Hg, ejection fraction lower than 0.45, mean pulmonary artery pressure higher than 15 mm Hg, transpulmonary gradient greater than 10 mm Hg, pulmonary artery abnormalities, and atrioventricular valve regurgitation. Mean preoperative risk score was 1.6 /-1.1. Mean New York Heart Association class was 2.6 +/- 0.5., Results: The operative mortality rate was 5% (1/21). Six patients (30%) had a major complication, four being prolonged effusions. One patient was lost to follow-up; the remaining 20 have been followed for a mean of 7.4 +/- 3.8 years. At follow-up, mean New York Heart Association class was 1.7 +/- 0.5. There has been one late death (5%) at 9 2/3 years, which was probably due to ventricular arrhythmia. Three patients (16%) have required and survived reoperation. During follow-up, 7 patients (37%) have had development of atrial arrhythmias requiring medication, and 2 have been treated for ventricular arrhythmias., Conclusions: These results indicate that properly selected adults can undergo the Fontan procedure with low morbidity and mortality. However, late-developing arrhythmias, need for reoperation, and decreasing ventricular function are serious problems that mandate careful follow-up.

Congenital heart disease in adults has become a special area of cardiovascular interest, but remains a relatively unfamiliar discipline. Advances in diagnostic and surgical techniques have had a striking impact on longevity in infants and children with congenital heart disease. Nevertheless, since true cures are rare, long-term care is obligatory for most if not all patients. In parallel with diagnostic and surgical developments, advances in medical management have had a major impact on life span in both postoperative and unoperated patients. Who will assume responsibility for the long-term care of these adult patients? Relatively few medical cardiologists are equipped to do so and relatively few pediatric cardiologists are sufficiently well versed with the accrued problems of aging. Accordingly, the current approach involves collaboration between pediatric and medical cardiologists. The purpose of this report is to underscore the importance of this collaboration, and to focus on 2 particular issues-the management of cyanotic congenital heart disease and the management of congenital heart disease and pregnancy.

Although it is generally assumed that fathers are absent from the lives of children being raised on AFDC, evidence from a case-control study in Worcester, Massachusetts, suggests that there is considerable father-child contact. In addition, multivariate modeling indicates that contact with fathers had a modest beneficial effect on children's behavior. Based on these study findings, negative traits of fathers (e.g., substance abuse, physical violence) appear to be associated with increased child behavior problems.

Many state Medicaid programs are implementing managed care, and more can be expected to do so in the future. Medicaid managed care will have an important impact on Medicaid recipients and uninsured people who live in cities. It will also pose significant new challenges for hospitals, community health centers, and clinics serving these populations and for social workers practicing in these settings. Social workers need to understand the reasons for Medicaid managed care's development and phenomenal growth and its likely impact or clients, service delivery, and access to care in medically underserved urban neighborhoods. This article identifies roles for social workers in supporting clients in the transition to Medicaid managed care and advocating for policies that will improve access to care for disadvantaged urban populations.

We place on record 2 infants with the DiGeorge syndrome and anomalous origin of the left pulmonary artery from the ascending aorta. We postulate that: (1) embryogenesis of anomalous origin of the left pulmonary artery from the ascending aorta might be due to the persistent fifth aortic arch connecting both arterial systems; (2) an anomalous pulmonary artery arising from the ascending aorta is part of the aortic arch abnormality accompanied by normal conotruncal septation; and (3) in the DiGeorge syndrome, cardiac anomalies that originate from the conotruncus or aortic arch, or both, may have the same embryologic mechanisms.
