Examining the Effect of the Affordable Care Act on Two Illinois Emergency Departments
Western Journal of Emergency Medicine, Volume 20, Issue 5
The emergency department (ED) has long served as a safety net for the uninsured and those with limited access to routine healthcare. This study aimed to compare the characteristics and severity of ED visits in an Illinois academic medical center (AMC) and community hospital (CH) of a single health system before and after the implementation of the Affordable Care Act (ACA).
The Three-Year Effect of Medicaid Expansion on Emergency Department Visits and Admissions
Annals of Emergency Medicine, 2020
Study objective: We examine the effect of the Medicaid expansion in 2014 under in the Patient Protection and Affordable Care Act on emergency department (ED) utilization and ED admission rates (fraction of ED visits that lead to hospital admission) during the first 3 postexpansion years (2014 to 2016). Methods: We compared ED utilization and ED admission rates in 151 EDs in 14 expansion states with those in 376 EDs in 14 nonexpansion states, using difference-indifferences methods with data from 3 national emergency medicine groups from 2013 to 2016. Results: In expansion states, the volume of Medicaid-paid ED visits increased 49% (95% confidence interval 34% to 65%), and the volume of uninsured visits decreased 44% (95% confidence interval-52% to-34%) relative to that of nonexpansion states. Both effects on payer mix leveled off during 2015. There was no significant relative change in overall ED utilization or overall ED admission rates in expansion versus nonexpansion states during the study. However, relative ED admission rates for uninsured patients declined 8% (95% confidence interval-18% to-2%) in expansion states. Conclusion: Large changes in payer mix in expansion versus nonexpansion states were observed but leveled off during 2015, with more Medicaid-paid visits and fewer uninsured visits in expansion states. Despite these large changes, during this 3-year period, there was no evidence that expansion affected either overall ED visit volume or ED admission rates. The relative decline in ED admission rates in expansion states among the uninsured may reflect a selection effect in which, among newly Medicaideligible persons, sicker persons were more likely to enroll than healthier ones.

Analysis of Emergency Department Utilization in Medicaid Expansion and Non-expansion States
Cureus, 2021
Introduction The Affordable Care Act has been debated since its initial enactment over a decade ago. One of the primary topics for discussion has been Medicaid expansion, which has created a schism across the United States. The effects of Medicaid expansion largely remain unclear. The purpose of this report is to elucidate how Medicaid expansion has impacted emergency department (ED) utilization by analyzing Medicaid expansion and non-expansion states to determine who visited the ED and the reason for the visit. Methods We conducted a retrospective analysis using de-identified electronic medical record (EMR) data from 56,423 patients and 33 different hospitals (18 Medicaid non-expansion and 15 Medicaid expansion) who visited the ED in 2019. We used geographical demographics and insurance status to categorize patients who visited the ED and ambulatory care sensitive conditions (ACSC) to identify the reasons for the visit. Logistic regression and chi-square analysis were used to analyze the data. Results We observed a significant relationship between Medicaid expansion and geographic region such that patients living in rural or semirural regions likely resided in Medicaid non-expansion states. Patients using self-pay were more likely to live in a Medicaid non-expansion state than a Medicaid expansion state (32.3% vs. 21.5%, p-value < 0.0001). Finally, there were no significant differences between the top five ACSC for Medicaid expansion and Medicaid non-expansion states but living in an expansion state was significantly (p < 0.01) related to being diagnosed with an ACSC (OR, 1.056; 95% CI, 1.013-1.100). Conclusion In conclusion, Medicaid expansion was associated with differences in the use of medical resources. Patients using Medicaid insurance who reside in Medicaid expansion states preferentially use the ED. Geographical location does play a role in ED utilization and ambulatory care sensitive condition diagnoses in patients. Despite these findings, the full effects of Medicaid expansion on ED utilization require further investigation. However, our research indicates that Medicaid expansion is not the singular solution in decreasing ED utilization and healthcare costs.
Medicaid managed care and preventable emergency department visits in the United States
PLOS ONE
Objectives In the United States the percentage of Medicaid enrollees in some form of Medicaid managed care has increased more than seven-fold since 1990, e.g., up from 11% in 1991 to 82% in 2017. Yet little is known about whether and how this major change in Medicaid insurance affects how recipients use hospital emergency rooms. This study compares the performance of Medicaid health maintenance organizations (HMOs) and fee-for-service (FFS) Medicaid regarding the occurrence of potentially preventable emergency department (ED) use. Methods Using data from the 2003-2015 Medical Expenditure Panel Survey (MEPS), a nationally representative survey of the non-institutionalized US population, we estimated multivariable logistic regression models to examine the relationship between Medicaid HMO status and potentially preventable ED use. To accommodate the composition of the Medicaid population, we conducted separate repeated cross-sectional analyses for recipients insured through both Medicaid and Medicare (dual eligibles) and for those insured through Medicaid only (non-duals). We explicitly addressed the possibility of selection bias into HMOs in our models using propensity score weighting. Results We found that the type of Medicaid held by a recipient, i.e., whether an HMO or FFS coverage, was unrelated to the probability that an ED visit was potentially preventable. This finding emerged both among dual eligibles and among non-duals, and it occurred irrespective of the adopted analytical strategy.
Changes in hospital service demand, cost, and patient illness severity following health reform

The objective of this study was to examine the association of patient- and county-level factors with the emergency department (ED) visits among adult fee-for-service (FFS) Medicaid beneficiaries residing in Maryland, Ohio, and West Virginia. A cross-sectional design using retrospective observational data was implemented. Patient-level data were obtained from 2010 Medicaid Analytic eXtract files. Information on county-level health-care resources was obtained from the Area Health Resource file and County Health Rankings file. In adjusted analyses, the following patient-level factors were associated with higher number of ED visits: African Americans (incidence rate ratios [IRR] = 1.47), Hispanics (IRR = 1.63), polypharmacy (IRR = 1.89), and tobacco use (IRR = 2.23). Patients with complex chronic illness had a higher number of ED visits (IRR = 3.33). The county-level factors associated with ED visits were unemployment rate (IRR = 0.94) and number of urgent care clinics (IRR = 0.96). Pat...

Background: Emergency department (ED) use is costly, and especially frequent among publicly insured populations in the US, who also disproportionately encounter financial (cost/coverage-related) and non-financial/practical barriers to care. The present study examines the distinct associations financial and non-financial barriers to care have with patterns of ED use among a publicly insured population. Methods: This observational study uses linked administrative-survey data for enrollees of Minnesota Health Care Programs to examine patterns in ED use-specifically, enrollee self-report of the ED as usual source of care, and past-year count of 0, 1, or 2+ ED visits from administrative data. Main independent variables included a count of seven enrollee-reported financial concerns about healthcare costs and coverage, and a count of seven enrollee-reported non-financial, practical barriers to access (e.g., limited office hours, problems with childcare). Covariates included health, health care, and demographic measures. Results: In multivariate regression models, only financial concerns were positively associated with reporting ED as usual source of care, but only non-financial barriers were significantly associated with greater ED visits. Regression-adjusted values indicated notable differences in ED visits by number of non-financial barriers: zero non-financial barriers meant an adjusted 78% chance of having zero ED visits (95% C.I.: 70.5%-85.5%), 15.9% chance of 1(95% C.I.: 10.4%-21.3%), and 6.2% chance (95% C.I.: 3.5%-8.8%) of 2+ visits, whereas having all seven non-financial barriers meant a 48.2% adjusted chance of zero visits (95% C.I.: 30.9%-65.6%), 31.8% chance of 1 visit (95% C.I.: 24.2%-39.5%), and 20% chance (95% C.I.: 8.4%-31.6%) of 2+ visits. Conclusions: Financial barriers were associated with identifying the ED as one's usual source of care but non-financial barriers were associated with actual ED visits. Outreach/literacy efforts may help reduce reliance on/perception of ED as usual source of care, whereas improved targeting/availability of covered services may help curb frequent actual visits, among publicly insured individuals.

Background: Earlier reports have documented growth of United States emergency department (ED) visits since the early 1990s. Objective: In this report, we describe recent trends in ED utilization and inpatient admissions in Maryland and District of Columbia hospitals from 2011 to 2013. Methods: We analyzed monthly ED visit and inpatient admission volumes from 53 acute care hospitals in Maryland and the District of Columbia from 2011 to 2013. Fixed-effect regression was used to assess the relationship between community-level demographics, hospital insurance mix, urgent care/retail clinic density, and hospitals participating in Maryland's Total Patient Revenue (TPR) pilot-a global payment program-and changes in ED visit and hospital admission volume from 2012 to 2013. Results: Across 53 Maryland and District of Columbia hospitals, ED visits grew 2.8% between 2011 and 2012. From 2012 to 2013, ED visits declined by 3.5%. Admissions declined by 3.3% from 2011 to 2012, then declined again 3.6% from 2012 to 2013. Community demographic or hospital insurance-mix variable and density of urgent care centers were not associated with lower ED visits. Inpatient admissions fell significantly more in hospitals participating in Maryland's TPR global payment pilot program. Conclusions: In 2013, ED visits in fell in Maryland and District of Columbia hospitals, and inpatient admission volumes fell from 2011 to 2013. This is a reversal of decades-long trends in higher health care utilization. These trends were not explained by demographics, insurance, or ED alternatives, however, falling admission rates were more pronounced in Maryland hospitals participating in global payment programs.

To determine the impact of Medicaid expansion on access to preventative care and non-emergent emergency department (ED) use for existing Medicaid enrollees. Study Design: The primary and secondary outcomes were receipt of annual preventive care visit and non- emergent emergency department (ED) visits, respectively. A logistic state-level, matched, difference in difference regression model was used for the primary analysis and a Poisson specification was used for the secondary analysis. Models controlled for patient characteristics and accounted for the complex longitudinal survey design.
