Context: Little is known about HIV patients' care experiences.Objective: To assess HIV patients' experiences with inpatient and outpatient care, and to assess the relationship and relative influence of patient characteristics and site of care on care experiences.Design: Cohort study.Setting: Patients with HIV receiving care outside of emergency rooms, prisons, or the military throughout the continental United States. One thousand seventy-four patients provided ratings of an inpatient stay and 2204 rated an outpatient visit; 818 patients provided evaluations of both inpatient and outpatient care.Patients: A national probability sample of persons in care for HIV from the HIV Cost and Services Utilization Study.Measurements: Outcome variables were rates of problems with, and global ratings of, inpatient and outpatient care.Results: Mean problem rates were 20.9% and 8.4% (lower score means fewer problems) for inpatient and outpatient care, respectively. On 9 of 10 of the individual inpatient report items, 15% or more of respondents reported problems. Global ratings of inpatient and outpatient care were 65.3 and 75.0 (0-100 scale, higher scores indicate better ratings), respectively. In multivariable models that controlled for site effects, the only patient characteristic that was consistently associated with problem rates and global ratings of care was mental health (P <0.0001 for both inpatient and outpatient care). Models including site effects explained two to four times as much variance as models excluding site effects.Conclusions: Inpatients with HIV reported higher problem rates with inpatient than outpatient care. Better provider-patient communication during inpatient stays is needed. For both inpatient and outpatient care, quality improvement efforts may be most productively focused on providers and processes of care at sites rather than on specific patient subgroups.

BACKGROUND: Medication measurement is crucial in assessing quality for chronic conditions yet agreement of alternate data sources remains uncertain. OBJECTIVES: To evaluate medication agreement between interviews, medical records, and pharmacy data; to assess data source contribution to attributing medication exposure; and to describe the impact of combining data sources on models that predict medication use. RESEARCH DESIGN: Prospective cohort study. SUBJECTS: Probability sample of HIV-infected participants in the HIV Cost and Services Utilization Study. MEASURES: Medications reported in 2267 interviews, 1936 medical records, and 457 pharmacy records were compared using crude agreement, kappa, and the proportion of average positive and negative agreement. The percent of medications reported in each source alone was used to assess their relative contribution to attributing exposure status. We performed weighted logistic regression in alternate data sources. RESULTS: Kappa varied from 0.38 for nucleoside reverse transcriptase inhibitors to 0.70 for protease inhibitors, when comparing drug classes in interview versus medical record, interview versus pharmacy data, and medical record versus pharmacy data. The percentage of medications reported in medical records was greater than that reported in interviews or pharmacy data. Pharmacy data contributed little to the attribution of medication exposure. Adding medication data to interview data did not appreciably change analytic models predicting medication use. CONCLUSIONS: For specific medications, agreement between alternative data sources is fair to substantial, but is lower for key drug classes. Relying on one data source may lead to misclassification of drug exposure status, but combining data sources does not change the results of analytic models predicting appropriate medication use.

Though HIV/AIDS has spread to rural areas, little empirical evidence is available on where patients living in these areas receive care. This article presents estimates of rural residents in care for HIV/AIDS, their demographic and health-related characteristics, information about whether they receive care in a rural or urban setting, and data on the drug therapies prescribed. The estimates come from the HIV Cost and Services Utilization Study (HCSUS), a nationally representative probability sample of HIV-infected adults receiving care in the contiguous United States. Regardless of the definition used--enrollment site, usual source of HIV care, or site of most recent hospitalization--almost three quarters of rural residents with HIV/AIDS obtained their health care in urban areas. The authors find that differences in the demographic characteristics of those using urban vs. rural care do not drive the decision on where to obtain care, with the primary difference being that people with a rural provider tend to be older. Rural residents with an urban usual source of HIV care incurred significant inconvenience in obtaining care--the majority said their care was not conveniently located, they had substantially longer mean travel times, and over 25% had put off obtaining care in the past 6 months because they did not have a way to get to their provider. Given the considerable burden this places on a chronically ill population,further research is needed to explore how provider supply and provider experience affect the decision to travel for care and how quality of care is affected.

Background: Although case management has been advocated as a method for improving the care of chronically ill persons, its effectiveness is poorly understood.Objective: To assess the effect of case managers on unmet need for supportive services and utilization of medical care and medications among HIV-infected persons.Design: Baseline and follow-up interview of a national probability sample.Setting: Inpatient and outpatient medical facilities in the United States.Participants: 2437 HIV-infected adults representing 217 081 patients receiving medical care.Measurements: Outcomes measured at follow-up were unmet need for supportive services, medical care utilization (ambulatory visits, emergency department visits, and hospitalizations), and use of HIV medication (receipt of antiretroviral therapy and prophylaxis against Pneumocystis carinii pneumonia and toxoplasmosis).Results: At baseline, 56.5% of the sample had contact with a case manager in the previous 6 months. In multiple logistic regression analyses that adjusted for potential confounders, contact with a case manager at baseline was associated with decreased unmet need for income assistance (odds ratio [OR], 0.57 [95% CI, 0.36 to 0.91]), health insurance (OR, 0.54 [CI, 0.33 to 0.89]), home health care (OR, 0.29 [CI, 0.15 to 0.56]), and emotional counseling (OR, 0.62 [CI, 0.41 to 0.94]) at follow-up. Contact with case managers was not significantly associated with utilization of ambulatory care (OR, 0.77 [CI, 0.57 to 1.04]), hospitalization (OR, 1.13 [CI, 0.84 to 1.54]), or emergency department visits (OR, 1.30 [CI, 0.97 to 1.73]) but was associated with higher utilization of two-drug (OR, 1.58 [CI, 1.23 to 2.03]) and three-drug (OR, 1.34 [CI, 1.00 to 1.80]) antiretroviral regimens and of treatment with protease inhibitors or non-nucleoside reverse transcriptase inhibitors (OR, 1.29 [CI, 1.02 to 1.64]) at follow-up.Conclusions: Case management appears to be associated with fewer unmet needs and higher use of HIV medications in patients receiving HIV treatment.

OBJECTIVES: This study identified age-related differences in diagnosis and progression of HIV by analyzing a nationally representative sample of HIV-infected adults under care in the United States. METHODS: We compared older (> or = 50 years) and younger participants stratified by race/ethnicity. Regression models controlled for demographic, therapeutic, and clinical factors. RESULTS: Older non-Whites more often had HIV diagnosed when they were ill. Older and younger patients were clinically similar. At baseline, however, older non-Whites had fewer symptoms and were less likely to have AIDS, whereas at follow-up they had a trend toward lower survival. CONCLUSIONS: Later HIV diagnosis in non-Whites merits public health attention; clinical progression in this group requires further study. [ABSTRACT FROM AUTHOR]

Background: Health-related quality of life refers to how well people are able to perform daily activities (functioning) and how they feel about their lives (well-being). The relationship between symptoms and health-related quality of life has not been fully explored.Objective: To estimate the association of HIV symptoms with health-related quality of life and with disability days.Design: Prospective cohort study.Setting: HIV providers in 28 urban and 24 rural randomly selected sites throughout the United States.Patients: Nationally representative sample of 2267 adults with known HIV infection who were interviewed in 1996 and again between 1997 and 1998.Measurements: Symptoms, two single-item global measures of health-related quality of life (perceived health and perceived quality of life), and disability days.Results: White patches in the mouth; nausea or loss of appetite; persistent cough, difficulty breathing, or difficulty catching one's breath; and weight loss were associated with more disability days and worse scores on both health-related quality-of-life measures. Headache; pain in the mouth, lips, or gums; dry mouth; and sinus infection, pain, or discharge were associated with worse perceived health. Pain in the mouth, lips, or gums; trouble with eyes; pain, numbness, or tingling of hands or feet; and diarrhea or loose or watery stools were associated with worse perceived quality of life. Headache and fever, sweats, or chills were associated with more disability days.Conclusions: Several symptoms are associated with worse health-related quality of life and more disability days in persons with HIV infection. In such patients, targeting specific symptoms may improve health-related quality of life and reduce disability. [ABSTRACT FROM AUTHOR]

OBJECTIVES: This study examines social, behavioral, and clinical correlates of perceived unmet need for oral health care for people with HIV infection. METHODS: Baseline in-person interviews with 2864 individuals were conducted with the HIV Cost and Services Utilization Study cohort, a nationally representative probability sample of HIV-infected persons in medical care. Bivariate and logistic regression analyses were conducted, with unmet need in the last 6 months as the dependent variable and demographic, social, behavioral, and disease characteristics as independent variables. RESULTS: We estimate that 19.3% of HIV-infected medical patients (n = 44,550) had a perceived unmet need for dental care in the last 6 months. The odds of having unmet dental needs were highest for those on Medicaid in states without dental benefits (odds ratio [OR] = 2.21), for others with no dental insurance (OR = 2.26), for those with incomes under $5000 (OR = 2.20), and for those with less than a high school education (OR = 1.83). Low CD4 count was not significant. CONCLUSIONS: Perceived unmet need was related more to social and economic factors than to stage of infection. An expansion of dental benefits for those on Medicaid might reduce unmet need for dental care. [ABSTRACT FROM AUTHOR]

OBJECTIVES: This study estimated the proportion of HIV-infected adults who have been assaulted by a partner or someone important to them since their HIV diagnosis and the extent to which they reported HIV-seropositive status as a cause of the violence. METHODS: Study participants were from a nationally representative probability sample of 2864 HIV-infected adults who were receiving medical care and were enrolled in the HIV Costs and Service Utilization Study. All interviews (91% in person, 9% by telephone) were conducted with computer-assisted personal interviewing instruments. Interviews began in January 1996 and ended 15 months later. RESULTS: Overall, 20.5% of the women, 11.5% of the men who reported having sex with men, and 7.5% of the heterosexual men reported physical harm since diagnosis, of whom nearly half reported HIV-seropositive status as a cause of violent episodes. CONCLUSIONS: HIV-related care is an appropriate setting for routine assessment of violence. Programs to cross-train staff in antiviolence agencies and HIV care facilities need to be developed for men and women with HIV infection. [ABSTRACT FROM AUTHOR]

The objective was to determine physicians' ratings of the clinical importance of common adult symptoms and to use these ratings to develop a new measure of symptom-specific use of health care services. We developed a list of common symptoms using the National Ambulatory Medical Care survey. We surveyed a random sample of internists, family physicians, general practitioners and emergency medicine physicians from the American Medical Association's Physician Masterfile and asked them to rate symptoms' seriousness, impact on quality of life and urgency of need for medical attention. The symptoms' prevalences were determined in a general population survey (National Access to Care Survey). Eleven items were classified as 'serious' (median seriousness ratings of 7 or higher on scale from 1 to 10); most of these also were judged to have high impact on quality of life. Another 12 items that were not judged 'serious' had median quality of life impact scores of 7 or higher and were classified as 'morbid'. Sixteen items did not meet criteria for either 'serious' or 'morbid' symptoms and were classified as 'intermediate'. Six other items had median seriousness and quality of life impact scores of 3 or less and were classified as 'benign'. A total of 24 of these items (7 'serious', 8 'morbid', 8 'intermediate' and 1 'benign') were selected to form the symptom-response measure. In the national survey, 26.3% reported one or more serious symptom, 30.6% reported one or more morbid symptom and 29.6% reported one or more intermediate symptom. This new instrument expands on earlier 'symptom-response' measures by including a larger number and a broader spectrum of symptoms. This measure should be useful to assess differences in patterns of health care use for particularly serious or morbid conditions; such variations may indicate problems with access to medical care.

Context: Studies of selected populations suggest that not all persons infected with human immunodeficiency virus (HIV) receive adequate care.Objective: To examine variations in the care received by a national sample representative of the adult US population infected with HIV.Design: Cohort study that consisted of 3 interviews from January 1996 to January 1998 conducted by the HIV Cost and Services Utilization Consortium.Patients and Setting: Multistage probability sample of 2864 respondents (68% of those targeted for sampling), who represent the 231400 persons at least 18 years old, with known HIV infection receiving medical care in the 48 contiguous United States in early 1996 in facilities other than emergency departments, the military, or prisons. The first follow-up consisted of 2466 respondents and the second had 2267 (65% of all surviving sampled subjects).Main Outcome Measures: Service utilization (<2 ambulatory visits, at least 1 emergency department visit that did not lead to hospitalization, at least 1 hospitalization) and medication utilization (receipt of antiretroviral therapy and prophylaxis against Pneumocystis carinii pneumonia).Results: Inadequate HIV care was commonly reported at the time of interviews conducted from early 1996 to early 1997 but declined to varying degrees by late 1997. Twenty-three percent of patients initially and 15% of patients subsequently had emergency department visits that did not lead to hospitalization, 30% initially and 26% subsequently of those who had CD4 cell counts below 0.20 x 10(9)/L did not receive P carinii pneumonia prophylaxis, and 41% initially and 15% subsequently of those who had CD4 cell counts below 0.50 x 10(9)/L did not receive antiretroviral therapy (protease inhibitor or nonnucleoside reverse transcriptase inhibitor). Inferior patterns of care were seen for many of these measures in blacks and Latinos compared with whites, the uninsured and Medicaid-insured compared with the privately insured, women compared with men, and other risk and/or exposure groups compared with men who had sex with men even after CD4 cell count adjustment. With multivariate adjustment, many differences remained statistically significant. Even by early 1998, fewer blacks, women, and uninsured and Medicaid-insured persons had started taking antiretroviral medication (CD4 cell count adjusted P values <.001 to <.005).Conclusions: Access to care improved from 1996 to 1998 but remained suboptimal. Blacks, Latinos, women, the uninsured, and Medicaid-insured all had less desirable patterns of care. Strategies to ensure optimal care for patients with HIV requires identifying the causes of deficiency and addressing these important shortcomings in care. [ABSTRACT FROM AUTHOR]

TO ASSESS THE understanding of safer sex among heterosexual adults, people enrolled in human immunodeficiency virus (HIV) education trials at a sexually transmitted disease (STD) clinic and a university student health service were surveyed concerning sexual behavior with their latest reported partner. Of 646 sexually active persons enrolled in the trials, 233 (36 percent) reported having had safer sex with their latest partner; 124 of them (53 percent) also reported having vaginal or anal intercourse without a condom during that sexual encounter. Among the 124 who reported safer sex despite having intercourse without a condom, only 23 percent reported asking partners about their HIV status, 46 percent had asked about intravenous drug use, and 47 percent had asked about the number of prior sexual partners. For 34 percent of those surveyed, the length of the sexual relationship with their latest partner was 1 month or less, and 18 percent estimated that this partner had had 11 or more prior sexual partners. STD clinic participants characterized intercourse without a condom as safer sex more often than student health service enrollees (76 percent versus 39 percent, P<0.001). The concept of safer sex is often misunderstood by persons engaging in behavior at risk for HIV transmission, and the level of misunderstanding differs among samples. Interventions to reduce transmission of HIV must confront misconceptions about the risk of sexual intercourse without condoms and include specific instructions understood by the targeted group. [ABSTRACT FROM AUTHOR]

We assessed why heterosexually active adults did not have 'safer sex' with their last sexual partner. Subjects enrolled in HIV education and testing trials at a sexually transmitted disease (STD) clinic and a university student health service (SHS) completed questionnaires about their last sexual partner's risk factors for HIV and whether they had safer sex with this partner. Of the 652 sexually active subjects, 61% reported not having safer sex with their last sexual partner and explained why. Low perceived risk of HIV infection was the most common reason, indicated by 62%, though most knew too little about their partner to ensure the encounter was low risk. Other reasons included condom unavailability (20%), the subject 'didn't want to' use a condom (19%), 'couldn't stop ourselves' (15%), the partner's influence (14%), and alcohol or drug use (11%). Thirty-one percent of subjects indicated more than one reason for not having safer sex. SHS subjects more often reported that the encounter was low risk for HIV transmission (p = 0.0001), while STD subjects more often reported condom unavailability (p = 0.002) and drug and alcohol use (p = 0.003). We conclude that there are many different factors promoting sexual behavior at risk of infection, combinations of which are important, and that these factors differ between samples. Preventive interventions must focus on the factors most important to the targeted population and may need to consider multiple factors simultaneously. [ABSTRACT FROM AUTHOR]

To evaluate how individuals infected with the human immunodeficiency virus (HIV) became aware of their infection, when they first suspected they were infected with HIV and factors associated with suspecting HIV infection, we surveyed 227 patients at an urban outpatient HIV clinic. Though nearly all patients acknowledged risk factors for HIV, 60% reported that they did not suspect that they were infected until they received a positive HIV antibody test result. Non-white patients were less likely to suspect HIV infection prior to testing than white subjects (p < 0.03). Subjects not suspecting infection more often received HIV testing through a screening program or during a medical encounter (p = 0.02) and were less likely to be told by others that they might be infected (p = 0.001) than patients suspecting infection prior to testing. Forty-eight percent of subjects who suspected HIV infection prior to testing waited one year or more before obtaining their HIV antibody test. Interventions to reduce faulty personal HIV risk perception are needed to promote earlier HIV diagnosis. [ABSTRACT FROM AUTHOR]

OBJECTIVES: This study examined whether disparities in the use of cardiovascular procedures exist among African Americans, Latinos, and Asians relative to White patients, within health insurance categories. METHODS: Hospital discharge records (n = 104,952) of Los Angeles Country, California, residents with possible coronary artery disease were analyzed. RESULTS: After adjustment for confounders, lower odds of procedure use were found for African American and Latino patients for most types of insurance. Asians and Pacific Islanders had odds of procedure use similar to those of White patients. Disparities were absent among the privately insured. CONCLUSIONS: Racial and ethnic disparities in procedure rates were evident in all types of insurance except private insurance. [ABSTRACT FROM AUTHOR]

Background: Hepatitis C (HCV) is a curable chronic infection, but lack of treatment uptake contributes to ongoing morbidity and mortality. State and national strategies for HCV elimination emphasize the pressing need for people with HCV to receive treatment., Objective: To identify provider-perceived barriers that hinder the initiation of curative HCV treatment and elimination of HCV in the USA., Approach: Qualitative semi-structured interviews with 36 healthcare providers who have evaluated patients with HCV in New York City, Western/Central New York, and Alabama. Interviews, conducted between 9/2021 and 9/2022, explored providers' experiences, perceptions, and approaches to HCV treatment initiation. Transcripts were analyzed using hybrid inductive and deductive thematic analysis informed by established health services and implementation frameworks., Key Results: We revealed four major themes: (1) Providers encounter professional challenges with treatment provision, including limited experience with treatment and perceptions that it is beyond their scope, but are also motivated to learn to provide treatment; (2) providers work toward building streamlined and inclusive practice settings-leveraging partnerships with experts, optimizing efficiency through increased access, adopting inclusive cultures, and advocating for integrated care; (3) although at times overwhelmed by patients facing socioeconomic adversity, increases in public awareness and improvements in treatment policies create a favorable context for providers to treat; and (4) providers are familiar with the relative advantages of improved HCV treatments, but the reputation of past treatments continues to deter elimination., Conclusions: To address the remaining barriers and facilitators providers experience in initiating HCV treatment, strategies will need to expand educational initiatives for primary care providers, further support local infrastructures and integrated care systems, promote public awareness campaigns, remove prior authorization requirements and treatment limitations, and address the negative reputation of outdated HCV treatments. Addressing these issues should be considered priorities for HCV elimination approaches at the state and national levels., (© 2024.

Objective: To develop a claims-based algorithm to determine the setting of a disease diagnosis., Data Sources and Study Setting: Medicare enrollment and claims data from 2014 to 2019., Study Design: We developed a claims-based algorithm using facility indicators, revenue center codes, and place of service codes to identify settings where HCV diagnosis first appeared. When the first appearance was in a laboratory, we attempted to associate HCV diagnoses with subsequent clinical visits. Face validity was assessed by examining association of claims-based diagnostic settings with treatment initiation., Data Collection/extraction Methods: Patients newly diagnosed with HCV and continuously enrolled in traditional Medicare Parts A, B, and D (12 months before and 6 months after index diagnosis) were included., Principal Findings: Among 104,454 patients aged 18-64 and 66,726 aged ≥65, 70.1% and 69%, respectively, were diagnosed in outpatient settings, and 20.2% and 22.7%, respectively in laboratory or unknown settings. Logistic regression revealed significantly lower odds of treatment initiation after diagnosis in emergency departments/urgent cares, hospitals, laboratories, or unclassified settings, than in outpatient visits., Conclusions: The algorithm identified the setting of HCV diagnosis in most cases, and found significant associations with treatment initiation, suggesting an approach that can be adapted for future claims-based studies., (© 2024 The Author(s).

The US government has established a national goal of hepatitis C virus (HCV) elimination by 2030. To date, most HCV elimination planning and activity have been at the state level. Fifteen states presently have publicly available HCV elimination plans. In 2019, Louisiana and Washington were the first states to initiate 5-year funded HCV elimination programs. These states differ on motivation for pursuing HCV elimination and ranking on several indicators. Simultaneously, however, they have emphasized several similar elimination components including HCV screening promotion through public awareness, screening expansion, surveillance enhancement (including electronic reporting and task force development), and harm reduction. The 13 other states with published elimination plans have proposed the majority of the elements identified by Louisiana and Washington, but several have notable gaps. Louisiana's and Washington's comprehensive plans, funding approaches, and programs provide a useful framework that can move states and the nation toward HCV elimination., Competing Interests: Financial Disclosures of Potential and Actual Conflicts of Interest: R.F. has received funds paid to his institution from Gilead Sciences, Inc, Abbvie, Merck & Co, Inc, and a consulting fee from Thera technologies.

Hispanic/Latino youth are less physically active than non-Hispanic/Latino youth. We assessed whether activity-specific parenting practices relate to moderate-to-vigorous physical activity (MVPA) and sedentary behavior among Hispanic/Latino youth, and whether cultural (acculturation) and neighborhood characteristics (perceived barriers to activity) relate to the use of parenting practice patterns. Using the Hispanic Community Children's Health Study/Study of Latino Youth (SOL Youth, n = 976 8-16-year-olds), we modeled linear regression associations between parenting practices and mean daily MVPA and sedentary behavior. Parenting practice patterns were then developed using k-means cluster analysis, and regressed on parental acculturation and neighborhood characteristics. Discipline predicted higher MVPA in females (β 1.89 [95% CI 0.11-3.67]), while Monitoring/Reinforcement predicted higher MVPA in males (β 4.71 [95% CI 0.68-8.74]). Three patterns were then identified: Negative Reinforcement (high Limit Setting and Discipline use), Positive Reinforcement (high Limit Setting and Monitoring/Reinforcement use), and Permissive Parenting (low parenting practice use). Higher acculturation predicted use of Positive Reinforcement. Activity-specific parenting practices are associated with activity in sex-specific ways among Hispanic/Latino youth, and cultural factors predict the use of parenting practices., (© 2023.

Objectives: Achieving diagnostic excellence on medical wards requires teamwork and effective team dynamics. However, the study of ward team dynamics in teaching hospitals is relatively underdeveloped. We aim to enhance understanding of how ward team members interact in the diagnostic process and of the underlying behavioral, psychological, and cognitive mechanisms driving team interactions., Methods: We used mixed-methods to develop and refine a conceptual model of how ward team dynamics in an academic medical center influence the diagnostic process. First, we systematically searched existing literature for conceptual models and empirical studies of team dynamics. Then, we conducted field observations with thematic analysis to refine our model., Results: We present a conceptual model of how medical ward team dynamics influence the diagnostic process, which serves as a roadmap for future research and interventions in this area. We identified three underexplored areas of team dynamics that are relevant to diagnostic excellence and that merit future investigation (1): ward team structures (e.g., team roles, responsibilities) (2); contextual factors (e.g., time constraints, location of team members, culture, diversity); and (3) emergent states (shared mental models, psychological safety, team trust, and team emotions)., Conclusions: Optimizing the diagnostic process to achieve diagnostic excellence is likely to depend on addressing all of the potential barriers and facilitators to ward team dynamics presented in our model., (© 2023 Walter de Gruyter GmbH, Berlin/Boston.)

Background: Ward rounds offer a rich environment for learning about team clinical reasoning. We aimed to assess how team clinical reasoning occurs on ward rounds to inform efforts to enhance the teaching of clinical reasoning., Methods: We performed focused ethnography of ward rounds over a 6-week period, during which we observed five different teams. Each day team comprised one senior physician, one senior resident, one junior resident, two interns and one medical student. Twelve 'night-float' residents who discussed new patients with the day team were also included. Field notes were analysed using content analysis., Findings: We analysed 41 new patient presentations and discussions on 23 different ward rounds. The median duration of case presentations and discussions was 13.0 minutes (IQR, 10.0-18.0 minutes). More time was devoted to information sharing (median 5.5 minutes; IQR, 4.0-7.0 minutes) than any other activity, followed by discussion of management plans (median 4.0 minutes; IQR, 3.0-7.8 minutes). Nineteen (46%) cases did not include discussion of a differential diagnosis for the chief concern. We identified two themes relevant to learning: (1) linear versus iterative approaches to team-based diagnosis and (2) the influence of hierarchy on participation in clinical reasoning discussions., Conclusion: The ward teams we observed spent far less time discussing differential diagnoses compared with information sharing. Junior learners such as medical students and interns contributed less frequently to team clinical reasoning discussions. In order to maximise student learning, strategies to engage junior learners in team clinical reasoning discussions on ward rounds may be needed., (© 2023 Association for the Study of Medical Education and John Wiley & Sons Ltd.)

Importance: Direct-acting antiviral (DAA) treatment for hepatitis C virus (HCV) infection is highly effective but remains underused. Understanding disparities in the delivery of DAAs is important for HCV elimination planning and designing interventions to promote equitable treatment., Objective: To examine variations in the receipt of DAA in the 6 months following a new HCV diagnosis., Design, Setting, and Participants: This retrospective cohort study used national Medicaid claims from 2017 to 2019 from 50 states, Washington DC, and Puerto Rico. Individuals aged 18 to 64 years with a new diagnosis of HCV in 2018 were included. A new diagnosis was defined as a claim for an HCV RNA test followed by an International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) diagnosis code, after a 1-year lookback period., Main Outcomes and Measures: Outcome was receipt of a DAA prescription within 6 months of diagnosis. Logistic regression was used to examine demographic factors and ICD-10-identified comorbidities associated with treatment initiation., Results: Among 87 652 individuals, 43 078 (49%) were females, 12 355 (14%) were age 18 to 29 years, 35 181 (40%) age 30 to 49, 51 282 (46%) were non-Hispanic White, and 48 840 (49%) had an injection drug use diagnosis. Of these individuals, 17 927 (20%) received DAAs within 6 months of their first HCV diagnosis. In the regression analyses, male sex was associated with increased treatment initiation (OR, 1.24; 95% CI, 1.16-1.33). Being age 18 to 29 years (OR, 0.65; 95% CI, 0.50-0.85) and injection drug use (OR, 0.84; 95% CI, 0.75-0.94) were associated with decreased treatment initiation. After adjustment for state fixed effects, Asian race (OR, 0.50; 95% CI, 0.40-0.64), American Indian or Alaska Native race (OR, 0.68; 95% CI, 0.55-0.84), and Hispanic ethnicity (OR, 0.81; 95% CI, 0.71-0.93) were associated with decreased treatment initiation. Adjustment for state Medicaid policy did not attenuate the racial or ethnic disparities., Conclusions: In this retrospective cohort study, HCV treatment initiation was low among Medicaid beneficiaries and varied by demographic characteristics and comorbidities. Interventions are needed to increase HCV treatment uptake among Medicaid beneficiaries and to address disparities in treatment among key populations, including younger individuals, females, individuals from minoritized racial and ethnic groups, and people who inject drugs.

Background: Childhood obesity disproportionately impacts Hispanics in the United States (US), the nation's largest ethnic minority population. However, even among Hispanic children, those born in the US are at increased risk of developing obesity than those not born in the US (i.e. first-generation Hispanics). The objective of this study is to assess whether ethnic and generational differences in the friend networks of Hispanic adolescents moderate the association between immigrant generation and weight., Methods: We analyzed data from first-generation, second-generation, and third-generation Hispanic 12 to 19 year-old participants in Wave 1 of the Longitudinal Study of Adolescent to Adult Health (Add Health). Using multivariable linear regression, we examined the association between generational status and body mass index (BMI), and whether the ethnic and generational composition of friends moderated that association., Results: Higher generational status was associated with higher BMI. The ethnic and generational composition of friends was not independently associated with BMI among Hispanic adolescents. However, a social network with a greater proportion of second-generation Hispanics was positively associated with BMI among first-generation Hispanics, and negatively associated with BMI among second-generation Hispanics., Conclusions: The generational status of peers in Hispanic adolescents' social networks, particularly the proportion that are second-generation Hispanic, moderates the positive association between immigrant generation and BMI. Moreover, this moderation effect is different across immigrant generations so that the proportion of second-generation adolescents within a social network is associated with higher BMI in first-generation Hispanic adolescents, but with lower BMI among those who are second-generation. These results were confirmed in sensitivity analyses. Our findings suggest that the generational composition of social networks alters the association between the generational status and weight of Hispanic adolescents, and thus that social factors within those networks may contribute to those associations., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Backgroung and Objectives: Under the Affordable Care Act, the US Centers for Medicare & Medicaid Services created the Physician Value-Based Payment Modifier Program and its successor, the Merit-Based Incentive Payment System, to tie physician payments to quality and cost. The addition of hospital length of stay (LOS) to these value-based physician payment models reflects its increasing importance as a metric of health care cost and efficiency and its association with adverse health outcomes. This study compared the Centers for Medicare & Medicaid Services-endorsed LOS risk-adjustment methodology with a novel methodology that accounts for pre-hospitalization clinical, socioeconomic status (SES), and admission-related factors as influential factors of hospital LOS., Methods: Using the 2014 New York, Florida, and New Jersey State Inpatient Database, we compared the observed-to-expected LOS of 2373102 adult admissions for 742 medical and surgical diagnosis-related groups (DRGs) by 3 models: ( a ) current risk-adjustment model (CRM), which adjusted for age, sex, number of chronic conditions, Elixhauser comorbidity score, and DRG severity weight, ( b ) CRM but modeling LOS using a generalized linear model (C-GLM), and (c) novel risk-adjustment model (NRM), which added to the C-GLM covariates for race/ethnicity, SES, discharge destination, weekend admission, and individual intercepts for DRGs instead of severity weights., Results: The NRM disadvantaged physicians for fewer medical and surgical DRGs, compared with both the C-GLM and CRM models (medical DRGs: 0.49% vs 13.17% and 10.89%, respectively; surgical DRGs: 0.30% vs 13.17% and 10.98%, respectively). In subgroup analysis, the NRM reduced the proportion of physician-penalizing DRGs across all racial/ethnic and socioeconomic groups, with the highest reduction among Whites, followed by low SES patients, and the lowest reduction among Hispanic patients., Conclusions: After accounting for pre-hospitalization socioeconomic and clinical factors, the adjusted LOS using the NRM was lower than estimates from the current Centers for Medicare & Medicaid Services-endorsed model. The current model may disadvantage physicians serving communities with higher socioeconomic risks., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Natural disasters continue to worsen in both number and intensity globally, but our understanding of their long-term consequences on individual and community health remains limited. As climate-focused researchers, we argue that a publicly funded research agenda that supports the comprehensive exploration of these risks, particularly among vulnerable groups, is urgently needed. This exploration must focus on the following three critical components of the research agenda to promote environmental justice in the age of climate change: (1) a commitment to long term surveillance and care to examine the health impacts of climate change over their life course; (2) an emphasis on interventions using implementation science frameworks; (3) the employment of a transdisciplinary approach to study, address, and intervene on structural disadvantage among vulnerable populations. Without doing so, we risk addressing these consequences in a reactive way at greater expense, limiting the opportunity to safeguard communities and vulnerable populations in the era of climate change.

Background: The frequency and destructiveness of hurricanes and related extreme weather events (e.g., cyclones, severe storms) have been increasing due to climate change. A growing body of evidence suggests that victims of hurricanes have increased incidence of cardiovascular disease (CVD), likely due to increased stressors around time of the hurricane and in their aftermath., Objectives: The objective was to systematically examine the evidence of the association between hurricanes (and related extreme weather events) and adverse CVD outcomes with the goal of understanding the gaps in the literature., Methods: A comprehensive literature search of population-level and cohort studies focused on CVD outcomes (i.e., myocardial infarction, stroke, and heart failure) related to hurricanes, cyclones, and severe storms was performed in the following databases from inception to December 2021: Ovid MEDLINE, Ovid EMBASE, Web of Science, and The Cochrane Library. Studies retrieved were then screened for eligibility against predefined inclusion/exclusion criteria. Studies were then qualitatively synthesized based on the time frame of the CVD outcomes studied and special populations that were studied. Gaps in the literature were identified based on this synthesis., Results: Of the 1,103 citations identified, 48 met our overall inclusion criteria. We identified articles describing the relationship between CVD and extreme weather, primarily hurricanes, based on data from the United States (42), Taiwan (3), Japan (2), and France (1). Outcomes included CVD and myocardial infarction-related hospitalizations (30 studies) and CVVD-related mortality (7 studies). Most studies used a retrospective study design, including one case-control study, 39 cohort studies, and 4 time-series studies., Discussion: Although we identified a number of papers that reported evaluations of extreme weather events and short-term adverse CVD outcomes, there were important gaps in the literature. These gaps included a ) a lack of rigorous long-term evaluation of hurricane exposure, b ) lack of investigation of hurricane exposure on vulnerable populations regarding issues related to environmental justice, c ) absence of research on the exposure of multiple hurricanes on populations, and d ) absence of an exploration of mechanisms leading to worsened CVD outcomes. Future research should attempt to fill these gaps, thus providing an important evidence base for future disaster-related policy. https://doi.org/10.1289/EHP11252.

Background: Hospitals serving a disproportionate share of racial/ethnic minorities have been shown to have poorer quality outcomes. It is unknown whether efficiencies in inpatient care, measured by length of stay (LOS), differ based on the proportion patients served by a hospital who are minorities., Objective: To examine the association between the racial/ethnic diversity of a hospital's patients and disparities in LOS., Design: Retrospective cross-sectional study., Participants: One million five hundred forty-six thousand nine hundred fifty-five admissions using the 2017 New York State Inpatient Database from the Healthcare Cost and Utilization Project., Main Measure: Differences in mean adjusted LOS (ALOS) between White and Black, Hispanic, and Other (Asian, Pacific Islander, Native American, and Other) admissions by Racial/Ethnic Diversity Index (proportion of non-White patients admitted to total patients admitted to that same hospital) in quintiles (Q1 to Q5), stratified by discharge destination. Mean LOS was adjusted for patient demographic, clinical, and admission characteristics and for individual intercepts for each hospital., Key Results: In both unadjusted and adjusted analysis, Black-White and Other-White mean LOS differences were smallest in the most diverse hospitals (Black-White: unadjusted, -0.07 days [-0.1 to -0.04], and adjusted, 0.16 days [95% CI: 0.16 to 0.16]; Other-White: unadjusted, -0.74 days [95% CI: -0.77 to -0.71], and adjusted, 0.01 days [95% CI: 0.01 to 0.02]). For Hispanic patients, in unadjusted analysis, the mean LOS difference was greatest in the most diverse hospitals (-0.92 days, 95% CI: -0.95 to -0.89) but after adjustment, this was no longer the case. Similar patterns across all racial/ethnic groups were observed after analyses were stratified by discharge destination., Conclusion: Mean adjusted LOS differences between White and Black patients, and White and patients of Other race was smallest in most diverse hospitals, but not differences between Hispanic and White patients. These findings may reflect specific structural factors which affect racial/ethnic differences in patient LOS., (© 2021. Society of General Internal Medicine.)

Older individuals with chronic health conditions are at highest risk of adverse clinical outcomes from COVID-19, but there is widespread belief that risk to younger, relatively lower-risk individuals is negligible. We assessed the rate and predictors of life-threatening complications among relatively lower-risk adults hospitalized with COVID-19. Of 3766 adults hospitalized with COVID-19 to three hospitals in New York City from March to May 2020, 963 were relatively lower-risk based on absence of preexisting health conditions. Multivariable logistic regression models examined in-hospital development of life-threatening complications (major medical events, intubation, or death). Covariates included age, sex, race/ethnicity, hypertension, weight, insurance type, and area-level sociodemographic factors (poverty, crowdedness, and limited English proficiency). In individuals ≥55 years old (n = 522), 33.3% experienced a life-threatening complication, 17.4% were intubated, and 22.6% died. Among those <55 years (n = 441), 15.0% experienced a life-threatening complication, 11.1% were intubated, and 5.9% died. In multivariable analyses among those ≥55 years, age (OR 1.03 [95%CI 1.01-1.06]), male sex (OR 1.72 [95%CI 1.14-2.64]), being publicly insured (versus commercial insurance: Medicare, OR 2.02 [95%CI 1.22-3.38], Medicaid, OR 1.87 [95%CI 1.10-3.20]) and living in areas with relatively high limited English proficiency (highest versus lowest quartile: OR 3.50 [95%CI 1.74-7.13]) predicted life-threatening complications. In those <55 years, no sociodemographic factors significantly predicted life-threatening complications. A substantial proportion of relatively lower-risk patients hospitalized with COVID-19 experienced life-threatening complications and more than 1 in 20 died. Public messaging needs to effectively convey that relatively lower-risk individuals are still at risk of serious complications., Competing Interests: The authors have declared that no competing interests exist.
