The effect of prescription drug insurance on the incidence of potentially inappropriate prescribing: Evidence from Medicare Part D.

The Medicare Part D program has been documented to increase the affordability and accessibility of drugs and improve the quality of prescription drug use; however, less is known about the equity impact of the Part D program on potentially inappropriate prescribing-specifically, incidences of polypharmacy and potentially inappropriate medication (PIM) use based on different racial/ethnic groups. Using a difference in the regression discontinuity design, we found that among Whites, Part D was associated with increases in polypharmacy and "broadly defined" PIM use, while the use of "always avoid" PIM remained unchanged. Conversely, Blacks and Hispanics reported no changes in such drug utilization patterns.

Improving health equity through health care systems research.

OBJECTIVE: To describe health equity research priorities for health care delivery systems and delineate a research and action agenda that generates evidence-based solutions to persistent racial and ethnic inequities in health outcomes. DATA SOURCES AND STUDY SETTING: This project was conducted as a component of the Agency for Healthcare Research and Quality's (AHRQ) stakeholder engaged process to develop an Equity Agenda and Action Plan to guide priority setting to advance health equity. Recommendations were developed and refined based on expert input, evidence review, and stakeholder engagement. Participating stakeholders included experts from academia, health care organizations, industry, and government. STUDY DESIGN: Expert group consensus, informed by stakeholder engagement and targeted evidence review. DATA COLLECTION/EXTRACTION METHODS: Priority themes were derived iteratively through (1) brainstorming and idea reduction, (2) targeted evidence review of candidate themes, (3) determination of preliminary themes; (4) input on preliminary themes from stakeholders attending AHRQ's 2022 Health Equity Summit; and (5) and refinement of themes based on that input. The final set of research and action recommendations was determined by authors' consensus. PRINCIPAL FINDINGS: Health care delivery systems have contributed to racial and ethnic disparities in health care. High quality research is needed to inform health care delivery systems approaches to undo systemic barriers and inequities. We identified six priority themes for research; (1) institutional leadership, culture, and workforce; (2) data-driven, culturally tailored care; (3) health equity targeted performance incentives; (4) health equity-informed approaches to health system consolidation and access; (5) whole person care; (6) and whole community investment. We also suggest cross-cutting themes regarding research workforce and research timelines. CONCLUSIONS: As the nation's primary health services research agency, AHRQ can advance equitable delivery of health care by funding research and disseminating evidence to help transform the organization and delivery of health care.

Medicaid Expansions and Access to Substance Abuse Treatment Services Among Limited English Proficiency Populations.

BACKGROUND: Although the myriad of provisions under the Affordable Care Act (ACA) have generally increased coverage and financial access to the health systems, language barriers represent a serious challenge to access to care among Limited English Proficiency (LEP) populations. OBJECTIVE: The aim of this study was to examine the effect of Medicaid expansions under the ACA on the availability of language services and Medicaid acceptance in substance abuse treatment (SAT) facilities. RESEARCH DESIGN: A quasi-experimental difference-in-differences design with multiple time periods was used to compare changes in the availability of language services and Medicaid as a payment source between Medicaid expansion and nonexpansion states. Facility-level observational data in the National Survey of Substance Abuse Treatment Services 2010-2019 was included. MEASURES: Availability of LEP services and Medicaid acceptance in the SAT facilities. RESULTS: The proportion of SAT facilities that provide LEP services increased from 40% in 2013 to 53% in 2019. The proportions by state are heterogeneous, ranging from approximately 20% to 70%. The ACA Medicaid expansions are not associated with changes in the availability of LEP services in the facilities. Moreover, Medicaid acceptance in the expansion states increased gradually following the expansion; however, the estimates are not statistically significant. CONCLUSION: The ACA Medicaid expansion had no impact on the availability of LEP services and the acceptance of Medicaid as a payment source in the SAT facilities.

Association between precarious employment and BMI in the United States.

OBJECTIVE: There is growing recognition that precarious employment is an important determinant of health, which may increase BMI through multiple mechanisms, including stress. It was investigated whether increases in precarious employment were associated with changes in BMI in the United States. METHODS: Data were from the National Longitudinal Survey of Youth adult cohort (1996-2016) (N = 7280). Thirteen indicators were identified to operationalize seven dimensions of precarious employment (range: 0-7, 7 indicating most precarious): material rewards, working-time arrangements, stability, workers' rights, collective organization, interpersonal relationships, and training. The precarious employment-BMI association was estimated using linear regression models and an instrumental variables approach; state- and individual-level firm sizes were the instruments for precarious employment. Models also included individual and year fixed effects and controlled for age, marital status, education, region, and industry. RESULTS: The average precarious employment score (PES) was 3.49 (95% CI: 3.46-3.52). The PES was the highest among Hispanic (4.04; 95% CI: 3.92-4.15) and non-Hispanic Black (4.02; 95% CI: 3.92-4.12) women with lower education. A 1-point increase in the PES was associated with a 2.18-point increase in BMI (95% CI: 0.30-4.01). CONCLUSIONS: Given that even small changes in weight affect chronic disease risk, policies to improve employment quality warrant consideration.

Examining the effects of social and cash transfer programs for homeless adults: Evidence from the Samaritan pilot.

Objective: To conduct a program evaluation of a technology-based intervention for a housing insecure population. Study design: We conduct a quantitative analysis of Samaritan pilot administrative records. Methods: Samaritan conducted an initial single-arm pilot of their technology platform among a housing insecure population (N = 500). Administrative records containing basic demographics and social determinants of health were analyzed as part of this evaluation. Results: Our analysis revealed that among the participants, roughly 60% reported one or more improvements in unmet social determinants of health, showing the greatest improvements in the areas of utilities and nutrition. A gender subgroup analysis also revealed a differential pattern of platform use to address social determinant needs, with women more likely to report improvements in housing and nutrition while men report improvements in income and hope categories. Conclusion: Samaritan, a technology-based intervention targeted at housing insecure individuals, aims to connect users to the financial and social capital necessary to improve their current situations. The results of the pilot demonstrate the potential role the Samaritan platform could play in addressing social determinant needs and insights on potentially useful technology-based intervention features for housing insecure populations.

Addressing hygiene needs of housing insecure populations: A qualitative analysis of Seattle and King County's mobile hygiene station intervention.

Objective: To evaluate the Seattle Public Utility mobile hygiene station program, a program deployed using public funds in response to the large-scale closures of public hygiene facilities due to COVID-19. Study design: We conduct a qualitative analysis using semi-structured interviews. Methods: We interviewed four Seattle Public Utility (SPU) and Public Health Seattle & King County (PHSKC) employees involved in the design, deployment, and management of the hygiene station intervention. Data were also collected from communications and reports released through SPU/PHSKC web sources. Results: Our analysis revealed factors affecting the implementation of the hygiene program included the rental of hygiene trailers, community partnership to mediate between housed and housing insecure populations, funding source and cost-effectiveness, geographic location of the units, and maintenance of the units to continue population hygiene support. Conclusion: The SPU/PHSKC hygiene station was designed to support the housing insecure and homeless by compensating for the large-scale closures of public restrooms and showers. Several logistical and financing challenges need to be addressed to ensure the continuity of the program.

Effects of inadequate coverage on healthcare utilization: A regression discontinuity analysis.

ABSTRACT: To examine the impact of inadequate health insurance coverage on physician utilization among older adults using a novel quasi-experimental design in the time period following the elimination of cost sharing for most preventative services under the US Affordable Care Act of 2010.The Medical Expenditure Panel Survey full year consolidated data files for the period 2010 to 2017 were used to construct a pooled cross-sectional dataset of adults aged 60 to 70. Regression discontinuity design was used to estimate the impact of transitioning between non-Medicare and Medicare plans on use of routine office-based physician visits and emergency room visits.For the overall population, gaining access to Medicare at age 65 is associated with a higher propensity to make routine office-based visits (2.94 percentage points [pp]; P < .01) and lower out-of-pocket costs (-23.86 pp; P < .01) Similarly, disenrollment from non-Medicare insurance plans at age 66 was associated with more routine office-based visits (3.01 pp; P < .01) and less out-of-pocket costs (-8.09 pp; P < .10). However, some minority groups reported no changes in visits and out-of-pocket costs or reported an increased propensity to make emergency department visits.Enrollment into Medicare from non-Medicare insurance plans was associated with increased use of routine office-based services and lower out-of-pocket costs. However, some subgroups reported no changes in routine visits or costs or an increased propensity to make emergency department visits. These findings suggest other nonfinancial, structural barriers may exist that limit patient's ability to access routine services.

Fixed effects analysis of the incidence of cardiovascular outcomes under managed care following the managed care backlash.

ABSTRACTS: To examine the impact of increased managed care activity on 30-day readmission and mortality for acute myocardial infarctions and congestive heart failure in U.S. hospitals following the managed care backlash against managed care cost containment practices.The Centers for Medicare and Medicaid Services (CMS) Hospital Compare files, CMS Hospital Cost Report, CMS Medicare Advantage Enrollment files, and Health Resources and Services Administration Area Resource File data for the period 2008 to 2011 were used to construct the study sample. Multivariate fixed effects regression with robust standard errors, hospital fixed effects, and year fixed effects were used to estimate the impact of managed care penetration on adverse cardiovascular outcomes. Our primary outcome measures were readmission and mortality for patients discharged with acute myocardial infarction and congestive heart failure for acute, non-federal hospitals with emergency rooms. To examine effects of hospital ownership status, not-for-profit hospitals were compared to proprietary hospitals.The main analysis revealed that an increase in managed care penetration was associated with a decline in both 30-day readmission and mortality for acute myocardial infarction and congestive heart failure. In the hospital ownership analysis, only the acute myocardial infarction results for proprietary hospitals was statistically significant. All hospital types reported similar congestive heart failure trends as the full sample; however, proprietary hospitals reported greater declines in readmission and mortality.Increased managed care activity is associated with reductions in hospital readmission and mortality following the legislative and consumer backlash against managed care, with differential impacts across hospital ownership type. These finding highlights the important role of managed care in creating quality improvements in the delivery of care in the hospital setting.
