Effect of expansions in state Medicaid eligibility on access to care and the use of emergency department services for adult Medicaid enrollees.

ABSTRACT: Medicaid enrollees typically report worse access to care than other insured populations. Expansions in Medicaid through less restrictive income eligibility requirements and the resulting influx of new enrollees may further erode access to care for those already enrolled in Medicaid.To assess the effect of previous Medicaid expansions on self-reported access to care and the use of emergency department services by Medicaid enrollees.Quasi-experimental difference-in-differences design among 1714 adult Medicaid enrollees in 10 states that expanded Medicaid between June 1, 2000, and October 1, 2009, and 5097 Medicaid enrollees in 14 bordering control states that did not expand Medicaid.Self-reported access to care and annualized emergency department use.Among states expanding their Medicaid program for adults, the mean income eligibility level increased from 82.6% to 144.2% of the federal poverty level. Income eligibility in matched control states remained constant at 77.1% of the federal poverty level. The proportion of adults reporting being enrolled in Medicaid increased from 7.2% to 8.8% in expansion states and from 6.1% to 6.4% in matched control states. In Medicaid program expansion states, the proportion of Medicaid enrollees reporting poor access to care declined from 8.5% before the expansion to 7.3% after the expansion. In matched control states, the proportion of Medicaid enrollees reporting poor access to care remained constant at 5.3%. The proportion of enrollees reporting any emergency department use decreased from 41.2% to 40.1% in expansion states and from 37.3% to 36.1% in matched control states. In the period following expansions, newly eligible enrollees reported poorer access to care than previously enrolled beneficiaries, although the overall difference between groups did not reach statistical significance.We found no evidence that expanding the number of individuals eligible for Medicaid coverage eroded perceived access to care or increased the use of emergency services among adult Medicaid enrollees.

Project description:BackgroundEnvironmental exposures such as traffic may contribute to asthma morbidity including recurrent emergency department (ED) visits. However, these associations are often confounded by socioeconomic status and health care access.ObjectiveThis study aims to assess the association between traffic density and recurrence of asthma ED visits in the primarily low income Medicaid population in New York State (NYS) between 2005 and 2015.MethodsThe primary outcome of interest was a recurrent asthma ED visit within 1-year of index visit. Traffic densities (weighted for truck traffic) were spatially linked based on home addresses. Bivariate and multivariate logistic regression analyses were conducted to identify factors predicting recurrent asthma ED visits.ResultsIn a multivariate model, Medicaid recipients living within 300-m of a high traffic density area were at a statistically significant risk of a recurrent asthma ED visit compared to those in a low traffic density area (OR = 1.31; 95% CI:1.24,1.38). Additionally, we evaluated effect measure modification for risk of recurrent asthma visits associated with traffic exposure by socio-demographic factors. The highest risk was found for those exposed to high traffic and being male (OR = 1.87; 95% CI:1.46,2.39), receiving cash assistance (OR = 2.11; 95% CI:1.65,2.72), receiving supplemental security income (OR = 2.21; 95% CI:1.66,2.96) and being in the 18.44 age group (OR = 1.59;95% CI 1.48,1.70) was associated with the highest risk of recurrent asthma ED visit. Black non-Hispanics (OR = 2.35; 95% CI:1.70,3.24), Hispanics (OR = 2.13; 95% CI:1.49,3.04) and those with race listed as "Other" (OR = 1.89 95% CI:1.13,3.16) in high traffic areas had higher risk of recurrent asthma ED visits as compared to White non-Hispanics in low traffic areas.ConclusionWe observed significant persistent disparities in asthma morbidity related to traffic exposure and race/ethnicity in a low-income population. Our findings suggest that even within a primarily low-income study population, socioeconomic differences persist. These differences in susceptibility in the extremely low-income group may not be apparent in health studies that use Medicaid enrollment as a proxy for low SES.

Project description:ImportanceTo date, 32 states and the District of Columbia have expanded Medicaid programs under the Patient Protection and Affordable Care Act. It is vital to understand whether expanded health insurance coverage of low-income individuals improves access to family planning services as a first step toward improving reproductive health outcomes.ObjectiveTo evaluate the association of Medicaid expansion coverage with access to birth control and family planning services among women of reproductive age enrolled in the Michigan expansion plan.Design, setting, and participantsIn a survey study, from January 13 through December 15, 2016, telephone surveys of a stratified sample of enrollees in Michigan's Section 1115 Medicaid Expansion waiver program, the Healthy Michigan Plan (HMP), were conducted. Interviewers completed surveys for 4090 sampled enrollees, of whom 1166 were women aged 19 to 44 years. Surveys were conducted with a computer-assisted telephone interviewing system in English, Arabic, and Spanish. The sample was weighted to 113 565 women. Dates of data analysis were from January 27 through September 18, 2017.Main outcomes and measuresSelf-reported change in access to birth control and family planning services through HMP (better, worse, about the same, or don't know/doesn't apply), compared with before enrollment.ResultsAmong the 1166 survey respondents aged 19 to 44 years (mean [SD] age, 31.0 [0.3] years) and the weighted sample of 113?565, 74.7% (95% CI, 72.2%-76.9%) lived in very-low-income households (<100% federal poverty level), 64.0% (95% CI, 60.5%-67.3%) reported at least 1 chronic medical condition, 23.5% (95% CI, 20.6%-26.6%) reported fair or poor health, and 17.7% (95% CI, 15.7%-19.9%) lived in rural settings. Overall, 35.5% (95% CI, 32.2%-39.0%) reported increased access to family planning services. After adjusting, those most likely to report increased access were women without health insurance coverage in the year preceding HMP enrollment (adjusted odds ratio [aOR], 2.02; 95% CI, 1.41-2.89) compared with women with health insurance for the full 12 months preceding enrollment; younger women (aOR for 19-24 years, 2.80 [95% CI, 1.75-4.50]; aOR for 25-34 years, 2.35 [95% CI, 1.60-3.45]) compared with women aged 35 to 44 years; and women with a recent visit to a primary care clinician (aOR 1.69; 95% CI, 1.03-2.76) compared with women without a primary care visit in the preceding 12 months.Conclusions and relevanceOne in 3 women of reproductive age reported better ability to access birth control and family planning services through HMP compared with before enrollment. This finding suggests that Medicaid expansion is associated with improved access to family planning services, which may enable low-income women to maintain optimal reproductive health.

Project description:ImportanceMedicaid recipients have consistently reported less timely access to specialists than patients with other types of coverage. By 2018, state Medicaid agencies will be required by the Center for Medicare and Medicaid Services (CMS) to enact time and distance standards for managed care organizations to ensure an adequate supply of specialist physicians for enrollees; however, there have been no published studies of whether these policies have significant effects on access to specialty care.ObjectiveTo compare ratings of access to specialists for adult Medicaid and commercial enrollees before and after the implementation of specialty access standards.Design, setting, and participantsWe used Consumer Assessment of Healthcare Providers and Systems survey data to conduct a quasiexperimental difference-in-differences (DID) analysis of 20 163 nonelderly adult Medicaid managed care (MMC) enrollees and 54 465 commercially insured enrollees in 5 states adopting access standards, and 37 290 MMC enrollees in 5 matched states that previously adopted access standards.Main outcomes and measuresReported access to specialty care in the previous 6 months.ResultsSeven thousand six hundred ninety-eight (69%) Medicaid enrollees and 28 423 (75%) commercial enrollees reported that it was always or usually easy to get an appointment with a specialist before the policy implementation (or at baseline) compared with 11 889 (67%) of Medicaid enrollees in states that had previously implemented access standards. Overall, there was no significant improvement in timely access to specialty services for MMC enrollees in the period following implementation of standard(s) (adjusted difference-in-differences, -1.2 percentage points; 95% CI, -2.7 to 0.1), nor was there any impact of access standards on insurance-based disparities in access (0.6 percentage points; 95% CI, -4.3 to 5.4). There was heterogeneity across states, with 1 state that implemented both time and distance standards demonstrating significant improvements in access and reductions in disparities.Conclusions and relevanceSpecialty access standards did not lead to widespread improvements in access to specialist physicians. Meaningful improvements in access to specialty care for Medicaid recipients may require additional interventions.

Project description:BackgroundSeveral states expanded Medicaid under the Affordable Care Act using Section 1115 waivers to implement healthy behavior incentive (HBI) programs, but the impact of this type of expansion relative to traditional expansion is not well understood.ObjectiveTo examine whether Medicaid expansion with healthy behavior incentive programs and traditional Medicaid expansion were associated with differential changes in coverage, access, and self-rated health outcomes among low-income adults.DesignDifference-in-differences analysis of American Community Survey and Behavioral Risk Factor Surveillance System data from 2011 to 2017.ParticipantsLow-income adults ages 19-64 in the Midwest Census region (American Community Survey, n = 665,653; Behavioral Risk Factor Surveillance System, n = 71,959).InterventionsExposure to either HBI waiver or traditional Medicaid expansion in the state of residence.Main measuresCoverage: Medicaid, private, or any health insurance coverage; access: routine checkup, personal doctor, delaying care due to cost; health: cancer screening, preventive care, healthy behaviors, self-reported health.Key resultsHealthy behavior incentive (HBI) and traditional expansion (TE) states experienced reductions in uninsurance (- 5.6 [- 7.5, - 3.7] and - 6.2 [- 8.1, - 4.4] percentage points, respectively) and gains in Medicaid (HBI, + 7.6 [2.4, 12.8]; TE, + 9.7 [5.9, 13.4] percentage points) relative to non-expansion states. Both expansion types were associated with increases in rates of having a personal doctor (HBI, + 3.8 [2.0, 5.6]; TE, + 5.9 [2.2, 9.6] percentage points) and mammography (HBI, + 5.6 [0.6, 10.6]; TE, + 7.3 [0.7, 13.9] percentage points). Meanwhile, checkups increased more in HBI than in TE states (p < 0.01), but no other changes in health care services differed between expansion types.ConclusionsMedicaid expansion was associated with improvements in coverage and access to care with few differences between expansion types.
