Transportation brokerage services and Medicaid beneficiaries' access to care.

ABSTRACT: OBJECTIVE: To examine the effect of capitated transportation brokerage services on Medicaid beneficiaries' access to care and expenditures. DATA SOURCES/STUDY SETTING: The study period from 1996 to 1999 corresponds to the period of a natural experiment during which Georgia and Kentucky implemented transportation brokerage services. Effects were estimated for asthmatic children and diabetic adults. STUDY DESIGN: We used difference-in-differences models to assess the effects of transportation brokerage services on access to care, measured by Medicaid expenditures and health services use. The study design is strengthened by the staggered implementation dates between states and within each state. PRINCIPAL FINDINGS: For asthmatic children, transportation brokerage services increased nonemergency transportation expenditures and the likelihood of using any services; reductions in monthly expenditures more than offsetting the increased transportation costs. For diabetic adults, nonemergency transportation costs decreased despite increased monthly use of health services; average monthly medical expenditures and the likelihood of hospital admission for an ambulatory care-sensitive condition (ACSC) also decreased. CONCLUSIONS: The shift to transportation brokerage services improved access to care among Medicaid beneficiaries and decreased the expenditures. The increase in access combined with reduced hospitalizations for asthmatic children and ACSC admissions for diabetic adults are suggestive of improvements in health outcomes.

Project description:BackgroundVertical integration is increasingly common among surgical specialties in the US; however, the effect of vertical integration on access to care for low-income populations remains poorly understood. We explored the characteristics of surgical practices associated with vertical integration and the effect of integration on surgical access for Medicaid populations.Study designUsing a survey of US office-based physician practices, we examined characteristics of 15 surgical subspecialties from 2007 to 2017, including provider sex and specialty, practice payer mix, surgical volume, and county socioeconomic status. Using multivariable logistic regression and time-series analysis, we evaluated practice and provider characteristics associated with vertical integration-our primary outcome-and practice Medicaid acceptance rates-our secondary outcome.ResultsOur analysis included 84,795 unique surgical practices (303,903 practice-years). The rate of vertical integration during the 10-year period was 18.0%, with 72.1% of surgical practices never integrating. Practices that integrated were more likely to accept Medicaid patients than practices that did not (81.0% vs 60.8%, p < 0.001). Accepting Medicaid increased the likelihood of vertical integration relative to practices that did not (odds ratio [OR] 4.20, 95% CI 3.93 to 4.49). Practices that integrated were more likely to accept Medicaid in the future (OR 2.61, 95% CI 2.40 to 2.83), even after adjusting for previous Medicaid acceptance and hospital and time fixed effects.ConclusionsSurgical practices caring for the underinsured are more likely to join larger health care systems, driven by market characteristics. Vertical integration is associated with future increased rates of Medicaid acceptance among practices, allowing for increased access to surgical care for vulnerable, low-income patients. The potential benefit of increased surgical access for low-income beneficiaries from vertical integration must be balanced with the potential for increased prices.

Project description:ImportanceMedicaid 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.ObjectiveTo assess the effect of previous Medicaid expansions on self-reported access to care and the use of emergency department services by Medicaid enrollees.Design, setting, and participantsQuasi-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.Main outcomes and measuresSelf-reported access to care and annualized emergency department use.ResultsAmong 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.Conclusions and relevanceWe 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:Aims and objectivesWe examined whether access to post-acute care services differed between individuals insured by Medicaid and commercial insurers and whether those differences explained emergency department utilisation 30 days post-hospitalisation.BackgroundTimely follow-up to community-based providers is a strategy to improve post-hospitalisation outcomes. However, little is known regarding the influence of post-acute care services on the likelihood of emergency department use post-hospitalisation for individuals insured by Medicaid.DesignWe conducted a retrospective observational study of electronic health record data from an academic medical centre in a large northeastern urban setting. The STROBE checklist was used in reporting this observational study.MethodsOur analysis included adults insured by Medicaid or commercial insurers who were discharged from medical services between 1 August-31 October 2017 (n = 785). Logistic regression models were used to examine the effects of post-acute care services (primary care, home health, specialty care) on the odds of an emergency department visit.ResultsPost-hospitalisation, 12% (n = 59) of individuals insured by Medicaid experienced an emergency department visit compared to 4.2% (n = 13) of individuals commercially insured. Having Medicaid insurance was associated with higher odds of emergency department visits post-hospitalisation (OR = 3.24). Having a home care visit or specialty care visit within 30 days post-discharge were significant predictors of lower odds of emergency department visits. Specific to specialty care visits, Medicaid was no longer a significant predictor of emergency department visits with specialty care being more influential (OR = 0.01).ConclusionsImproving connections to appropriate post-acute care services, specifically specialty care, may improve outcomes among individuals insured by Medicaid.Relevance to clinical practiceHospital-based nurses, including those in direct care, case management and discharge planning, play an important role in facilitating referrals and scheduling appointments prior to discharge. Individuals insured by Medicaid may require additional support in accessing these services and nurses are well-positioned to facilitate care continuity.
