Affordable Care Act and healthcare delivery: A comparison of California and Florida hospitals and emergency departments.

ABSTRACT:

Importance

The Affordable Care Act (ACA) has expanded access to health insurance for millions of Americans, but the impact of Medicaid expansion on healthcare delivery and utilization remains uncertain.

Objective

To determine the early impact of the Medicaid expansion component of ACA on hospital and ED utilization in California, a state that implemented the Medicaid expansion component of ACA and Florida, a state that did not.

Design

Analyze all ED encounters and hospitalizations in California and Florida from 2009 to 2014 and evaluate trends by payer and diagnostic category. Data were collected from State Inpatient Databases, State Emergency Department Databases and the California Office of Statewide Health Planning and Development.

Setting

Hospital and ED encounters.

Participants

Population-based study of California and Florida state residents.

Exposure

Implementation of Medicaid expansion component of ACA in California in 2014.

Main outcomes or measures

Changes in ED visits and hospitalizations by payer, percentage of patients hospitalized after an ED encounter, top diagnostic categories for ED and hospital encounters.

Results

In California, Medicaid ED visits increased 33% after Medicaid expansion implementation and self-pay visits decreased by 25% compared with a 5.7% increase in the rate of Medicaid patient ED visits and a 5.1% decrease in rate of self-pay patient visits in Florida. In addition, California experienced a 15.4% increase in Medicaid inpatient stays and a 25% decrease in self pay stays. Trends in the percentage of patients admitted to the hospital from the ED were notable; a 5.4% decrease in hospital admissions originating from the ED in California, and a 2.1% decrease in Florida from 2013 to 2014.

Conclusions and relevance

We observed a significant shift in payer for ED visits and hospitalizations after Medicaid expansion in California without a significant change in top diagnoses or overall rate of these ED visits and hospitalizations. There appears to be a shift in reimbursement burden from patients and hospitals to the government without a dramatic shift in patterns of ED or hospital utilization.

Project description:BackgroundPractitioners expected the Affordable Care Act (ACA) to increase availability of health services and access to treatment for Americans with substance use disorders (SUDs). Yet research has not examined the associations among ACA enrollment mechanisms, deductibles, and the use of SUD treatment and other healthcare services. Understanding these relationships can inform future healthcare policy.MethodsWe conducted a longitudinal analysis of patients with SUDs newly enrolled in the Kaiser Permanente Northern California health system in 2014 (N = 6957). Analyses examined the likelihood of service utilization (primary care, specialty SUD treatment, psychiatry, inpatient, and emergency department [ED]) over three years after SUD diagnosis, and associations with enrollment mechanisms (ACA Exchange vs. other), deductibles (none, $1-$999 [low] and ≥$1000 [high]), membership duration, psychiatric comorbidity, and demographic characteristics. We also evaluated whether the enrollment mechanism moderated the associations between deductible limits and utilization likelihood.ResultsService utilization was highest in the 6 months after SUD diagnosis, decreased in the following 6 months, and remained stable in years 2-3. Relative to patients with no deductible, those with a high deductible had lower odds of using all health services except SUD treatment; associations with primary care and psychiatry were strongly negative among Exchange enrollees. Among non-Exchange enrollees, patients with deductibles were more likely than those without deductibles to receive SUD treatment. Exchange enrollment compared to other mechanisms was associated with less ED use. Psychiatric comorbidity was associated with greater use of all services. Nonwhite patients were less likely to initiate SUD and psychiatry treatment.ConclusionsHigher deductibles generally were associated with use of fewer health services, especially in combination with enrollment through the Exchange. The role of insurance factors, psychiatric comorbidity and race/ethnicity in health services for people with SUDs are important to consider as health policy evolves.

Project description:Study objectiveThe 2010 provision of the Patient Protection and Affordable Care Act (ACA) extended eligibility for health insurance for young adults aged 19 to 25 years. It is unclear, however, how expanded coverage changes health care behavior and promotes efficient use of emergency department (ED) services. Our objective was to use population-level emergency department data to characterize any changes in diagnoses seen in ED among young adults since the implementation of the ACA dependent coverage expansion.MethodsWe performed a difference-in-differences analysis of 2009 to 2011 ED visits from California, Florida, and New York, using all-capture administrative data to determine how the use of ED services changed for clinical categories after the ACA provision among young adults aged 19 to 25 years compared with slightly older adults unaffected by the provision, aged 26 to 31 years.ResultsWe analyzed a total of 10,158,254 ED visits made by 4,734,409 patients. After the implementation of the 2010 ACA provision, young adults had a relative decrease of 0.5% ED visits per 1,000 people compared with the older group. For the majority of diagnostic categories, young adults' rates and risk of visit did not change relative to that of slightly older adults after the implementation of the ACA. However, although young adults' ED visits significantly increased for mental illnesses (2.6%) and diseases of the circulatory system (eg, nonspecific chest pain) (4.8%), visits decreased for pregnancy-related diagnoses and diseases of the skin (eg, cellulitis, abscess) compared with that of the older group (3.7% and 3.1%, respectively).ConclusionOur results indicate that increased coverage has kept young adults out of the ED for specific conditions that can be cared for through access to other channels. As EDs face capacity challenges, these results are encouraging and offer insight into what could be expected under further insurance expansions from health care reform.

Project description:ObjectiveTo determine whether changes in emergency department use associated with Medicaid expansions differed between states undergoing waiver and traditional expansions.MethodsDesign: This study was a cross-sectional difference-in-difference and event studies of Medicaid Expansion among states that expanded during or after 2014. Setting: We used a nationally representative cross-sectional survey from all 50 United States and the District of Columbia from 2010 to 2016. Participants: Adults aged 19-65 years with incomes <138% of the federal poverty level were included. Main Outcomes and Measures: Main outcomes were self-reported emergency department (ED) utilization in the last 12 months.ResultsIndividuals in states across all expansion types were not more likely to report any ED use in the previous year (2.8 percentage point increase [0.0-5.5], P = 0.052) but were more likely to report visiting an ED 2 times or more in the previous year (2.0 [0.0-4.1], P = 0.049) than those in non-expansion states. Individuals in states undergoing traditional expansions likewise were not more likely to report any ED use (2.2 [-0.7 to 1.5], P = 0.136) but were more likely to report visiting an ED 2 times or more in the previous year (2.3 [0.1-4.4], P = 0.038). Conversely, individuals in waiver states were more likely to report increase in any ED use (5.6 [0.3-11.0], P = 0.038), but were not more likely to report use of EDs 2 times or more in the previous year (0.8 [-3.2-4.9], P = 0.688). The differences between traditional and waiver states in any ED use and ED use 2 times or more in the previous 12 months were not statistically significant (P = 0.215 and P = 0.501, respectively).ConclusionsThree years after expanding Medicaid under the Affordable Care Act, there is little evidence of differences between traditional and waiver expansion states in changes in any ED use or intensive ED use. Future studies should investigate longer term changes in ED use.
