The role of data in health care disparities in medicaid managed care

BACKGROUND: The Affordable Care Act includes provisions to standardize the collection of data on health care quality that can be used to measure disparities. We conducted a qualitative study among leaders of Medicaid managed care plans, that currently have access to standardized quality data stratified by race and ethnicity, to learn how they use it to address disparities. METHODS: We conducted semi-structured interviews with 21 health plan leaders across 9 Medicaid managed care plans in California. We used purposive sampling to maximize heterogeneity in geography and plan type (e.g., non-profit, commercial). We performed a thematic analysis based on iterative coding by two investigators. RESULTS: We found 4 major themes. Improving overall quality was tightly linked to a focus on standardized metrics that are integral to meeting regulatory or financial incentives. However, reducing disparities was not driven by standardized data, but by a mix of factors. Data were frequently only examined by race and ethnicity when overall performance was low. Disparities were attributed to either individual choices or cultural and linguistic factors, with plans focusing interventions on recently immigrated groups. CONCLUSIONS: While plans' efforts to address overall quality were often informed by standardized data, actions to reduce disparities were not, at least partly because there were few regulatory or financial incentives driving meaningful use of data on disparities. Standardized data, as envisaged by the Affordable Care Act, could become more useful for addressing disparities if they are combined with policies and regulations that promote health care equity

Changing home care aides: Differences between family and non-family care in California Medicaid home and community-based services.

In California Medicaid home-and-community-based services (HCBS), recipients' family members receive payment as home care aides (HCAs). We analyzed data on first-time HCBS recipients to examine factors associated with the likelihood of switching HCAs within the first year of services. Those with family HCAs were less than half as likely to change than those with non-family HCAs and racial/ethnic minorities with non-family HCAs had the highest switching rates. Lower wages and local unemployment were associated with switching of non-family HCAs but not family HCAs. Policymakers can foster continuity of home care by paying family members for home care and raising worker wages

Concentration of Physician Services Across Insurers and Effects on Quality: Early Evidence From Medicare Advantage.

BackgroundA growing proportion of Medicare beneficiaries is covered by private insurers through Medicare Advantage, yet little is known about how these plans are structured in terms of relationships with physicians and implications for quality of care.ObjectiveThe objective of this study was to assess whether greater physician concentration of services across insurers was associated with higher quality in Medicare Advantage (MA), overall and particularly among MA insurers serving a high proportion of vulnerable enrollees.Research designA retrospective cohort design with regression analysis.Data sourcesThe primary dataset was 2014 MA encounter records submitted by insurers to the Centers for Medicare and Medicaid Services, covering 600,329 physicians across 119 insurers. These data were merged with Centers for Medicare and Medicaid Services data on MA contract quality rating as well as physician characteristics in the Medicare Data on Provider Practice and Specialty file.MeasuresTwo measures were generated to capture the concentration of physician services across insurers: the percentage of a physician's Medicare services which was through MA (MA penetration); and the percentage of a physician's MA services with a specific insurer (insurer share of MA services).ResultsGreater MA penetration and insurer share of MA services were each associated with higher MA plan quality. The relationship between insurer share and quality was stronger in contracts with a relatively high percentage of disabled enrollees.ConclusionGreater physician concentration of services across MA insurers was associated with a higher quality of care overall and especially among vulnerable enrollees

Challenges and Opportunities to Updating Prescribing Information for Longstanding Oncology Drugs.

A number of important drugs used to treat cancer-many of which serve as the backbone of modern chemotherapy regimens-have outdated prescribing information in their drug labeling. The Food and Drug Administration is undertaking a pilot project to develop a process and criteria for updating prescribing information for longstanding oncology drugs, based on the breadth of knowledge the cancer community has accumulated with the use of these drugs over time. This article highlights a number of considerations for labeling updates, including selecting priorities for updating; data sources and evidentiary criteria; as well as the risks, challenges, and opportunities for iterative review to ensure prescribing information for oncology drugs remains relevant to current clinical practice

Integrating Health Care for the Most Vulnerable: Bridging the Differences in Organizational Cultures Between US Hospitals and Community Health Centers

Policymakers have increasingly promoted health services integration to improve quality and efficiency. The US health care safety net, which comprises providers of health care to uninsured, Medicaid, and other vulnerable patients, remains a largely fragmented collection of providers. We interviewed leadership from safety net hospitals and community health centers in 5 US cities (Boston, MA; Denver, CO; Los Angeles, CA; Minneapolis, MN; and San Francisco, CA) throughout 2013 on their experiences with service integration. We identify conflicts in organizational mission, identity, and consumer orientation that have fostered reluctance to enter into collaborative arrangements. We describe how smaller scale initiatives, such as capitated model for targeted populations, health information exchange, and quality improvements led by health plans, can help bridge cultural differences to lay the groundwork for developing integrated care programs

Cardiac Procedures among American Indians and Alaska Natives compared to Non-Hispanic Whites Hospitalized with Ischemic Heart Disease in California

BackgroundAmerican Indians/Alaska Natives (AIAN) experience a high burden of cardiovascular disease with rates for fatal and nonfatal heart disease approximately twofold higher than the U.S. population.ObjectiveTo determine if disparities exist in cardiac procedure rates among AIAN compared to non-Hispanic whites hospitalized in California for ischemic heart disease defined as acute myocardial infarction or unstable angina.DesignCross-sectional study. EVENTS: A total of 796 ischemic heart disease hospitalizations among AIAN and 90971 among non-Hispanic whites in 37 of 58 counties in California from 1998-2002.MeasurementsCardiac catheterization, percutaneous cardiac intervention, and coronary artery bypass graft surgery procedure rates from hospitalization administrative data.Main resultsAIAN did not have lower cardiac procedure rates for cardiac catheterization and percutaneous cardiac intervention compared to non-Hispanic whites (unadjusted OR 1.00, 95% CI 0.87-1.16 and OR 1.04, 95% CI 0.90-1.20, respectively). Adjustment for age, sex, comorbidities, and payer source did not alter the results (adjusted OR 0.95, 95% CI 0.82-1.10 and OR 0.98, 95% CI 0.85-1.14, respectively). We found higher odds (unadjusted OR 1.36, 95% CI 1.09-1.70) for receipt of coronary artery bypass graft surgery among AIAN hospitalized for ischemic heart disease compared to non-Hispanic whites which after adjustment attenuated some and was no longer statistically significant (adjusted OR 1.26, 95% CI 1.00-1.58).ConclusionAIAN were not less likely to receive cardiac procedures as non-Hispanic whites during hospitalizations for ischemic heart disease. Additional research is needed to determine whether differences in specialty referral patterns, patients' treatment preferences, or outpatient management may explain some of the health disparities due to cardiovascular disease that is found among AIAN
