Medicaid Expansion and Health Plan Quality in Medicaid Managed Care.

ABSTRACT: OBJECTIVE:To assess the effect of the 2014 Medicaid expansion on Medicaid managed care plan quality. DATA SOURCES:Three composite measures of plan-level quality constructed from the Health Care Effectiveness Data and Information Set. STUDY SETTING:One hundred and sixty-three plans in 27 Medicaid expansion states and 100 plans in 14 nonexpansion states. STUDY DESIGN:Quasi-experimental difference-in-differences (DID) analysis, comparing quality before (2011-13) and after (2014-15) Medicaid expansion in states that elected to expand Medicaid eligibility and those that did not. PRINCIPAL FINDINGS:Mean plan enrollment increased from 130,533 to 274,259 in expansion states and from 105,449 to 148,194 in nonexpansion states. The proportion of enrollees receiving recommended preventive care increased from 62.6 to 65.2 percent in expansion states and from 59.3 to 62.5 percent in nonexpansion states (adjusted DID: -0.7 percentage points [95% CI -2.2, 0.7]). The proportion of enrollees receiving recommended chronic disease care management increased from 65.4 to 66.0 percent in expansion states and from 62.5 to 63.1 percent in nonexpansion states (adjusted DID: 1.1 percentage points [95% CI -0.5, 2.6]). We observed similar patterns for the receipt of recommended maternity care. CONCLUSIONS:Medicaid expansion increased enrollment in managed care plans, but it did not result in erosion of quality.

Project description:ImportanceState Medicaid programs have increasingly contracted with insurers to provide medical care services for enrollees (Medicaid managed care plans). Insurers that provide these plans can exit Medicaid programs each year, with unclear effects on quality of care and health care experiences.ObjectiveTo determine the frequency and interstate variation of health plan exit from Medicaid managed care and evaluate the relationship between health plan exit and market-level quality.Design, setting, and participantsRetrospective cohort of all comprehensive Medicaid managed care plans (N?=?390) during the interval 2006-2014.ExposuresPlan exit, defined as the withdrawal of a managed care plan from a state's Medicaid program.Main outcomes and measuresEight measures from the Healthcare Effectiveness Data and Information Set were used to construct 3 composite indicators of quality (preventive care, chronic disease care management, and maternity care). Four measures from the Consumer Assessment of Healthcare Providers and Systems were combined into a composite indicator of patient experience, reflecting the proportion of beneficiaries rating experiences as 8 or above on a 0-to-10-point scale. Outcome data were available for 248 plans (68% of plans operating prior to 2014, representing 78% of beneficiaries).ResultsOf the 366 comprehensive Medicaid managed care plans operating prior to 2014, 106 exited Medicaid. These exiting plans enrolled 4?848?310 Medicaid beneficiaries, with a mean of 606?039 beneficiaries affected by plan exits annually. Six states had a mean of greater than 10% of Medicaid managed care recipients enrolled in plans that exited, whereas 10 states experienced no plan exits. Plans that exited from a state's Medicaid market performed significantly worse prior to exiting than those that remained in terms of preventive care (57.5% vs 60.4%; difference, 2.9% [95% CI, 0.3% to 5.5%]), maternity care (69.7% vs 73.6%; difference, 3.8% [95% CI, 1.7% to 6.0%]), and patient experience (73.5% vs 74.8%; difference, 1.3% [95% CI, 0.6% to 1.9%]). There was no significant difference between exiting and nonexiting plans for the quality of chronic disease care management (76.2% vs 77.1%; difference, 1.0% [95% CI, -2.1% to 4.0%]). There was also no significant change in overall market performance before and after the exit of a plan: 0.7-percentage point improvement in preventive care quality (95% CI, -4.9 to 6.3); 0.2-percentage point improvement in chronic disease care management quality (95% CI, -5.8 to 6.2); 0.7-percentage point decrease in maternity care quality (95% CI, -6.4 to 5.0]); and a 0.6-percentage point improvement in patient experience ratings (95% CI, -3.9 to 5.1). Medicaid beneficiaries enrolled in exiting plans had access to coverage for a higher-quality plan, with 78% of plans in the same county having higher quality for preventive care, 71.1% for chronic disease management, 65.5% for maternity care, and 80.8% for patient experience.Conclusions and relevanceBetween 2006 and 2014, health plan exit from the US Medicaid program was frequent. Plans that exited generally had lower quality ratings than those that remained, and the exits were not associated with significant overall changes in quality or patient experience in the plans in the Medicaid market.

Project description:BackgroundMedicaid expansion substantially increased health insurance coverage, but its effect on the delivery of preventative health care is unclear.ObjectiveThe objective of this study was to assess the impact of Medicaid expansion on the receipt of 15 different measures of preventive care including cancer screening, cardiovascular risk reduction, diabetes care, and other primary care measures.Research designWe performed serial cross-sectional analysis of Behavioral Risk Factor Surveillance System (BRFSS) survey data from 2012 to 2017. We used a quasi-experimental design with difference-in-differences (DiD) analyses to examine changes in preventative health care delivery over 3 time periods in Medicaid expansion compared with nonexpansion states.SubjectsWe included low-income (<138% federal poverty level) nonelderly (age younger than 65 y) adults residing in 46 US states.MeasuresOur predictor was residing in a Medicaid expansion state (24 states) versus nonexpansion state (19 states). Our primary outcomes were preventative health care services, which we categorized as cancer screening (breast cancer, cervical cancer, and colorectal cancer); cardiovascular risk reduction (serum cholesterol screening in low-risk groups, serum cholesterol monitoring in high-risk groups, and aspirin use); diabetes care (serum cholesterol monitoring, hemoglobin A1c monitoring, foot examination, eye examination, and influenza vaccination, and pneumonia vaccination); and other primary care measures [influenza vaccination, alcohol use screening, and human immunodeficiency virus (HIV) screening].ResultsSurvey responses from 500,495 low-income nonelderly adults from 2012 to 2017 were included in the analysis, representing 68.2 million US adults per year. Of the 15 outcomes evaluated, we did not detect statistically significant differences in cancer screening (3 outcomes), cholesterol screening or monitoring (2 outcomes), diabetes care (6 outcomes), or alcohol use screening (1 outcome) in expansion compared with nonexpansion states. Aspirin use (DiD 8.8%, P<0.001), influenza vaccination (DiD 1.4%, P=0.016), and HIV screening (DiD 1.9%, P=0.004) increased in expansion states compared with nonexpansion states.ConclusionsMedicaid expansion was associated with an increase in aspirin use, influenza vaccination, and HIV screening in expansion states. Despite improvements in access to care, including health insurance, having a primary care doctor, and routine visits, Medicaid expansion was not associated with improvements in cancer screening, cholesterol monitoring, diabetes care, or alcohol use screening. Our findings highlight implementation challenges in delivering high-quality primary care to low-income populations.
