Uninsured Hospital and Emergency Department Rates Drop Due to Medicaid Expansion

Rates of uninsured hospital stays and emergency department visits fell sharply among different groups in states that have expanded Medicaid eligibility, according to a study published in Health Services Research. Uninsured hospital stays decreased by an average 39 percent per capita in expansion states for all groups except for young women. In nonexpansion states, uninsured inpatient rates remained unchanged or increased slightly. The study, based on AHRQ’s Healthcare Cost and Utilization Project data from 2011 to 2015, also found that the positive change in health outcomes was greater in states with larger populations eligible to purchase insurance coverage.

Changes in hospital service demand, cost, and patient illness severity following health reform.

Abstract

OBJECTIVE:

To estimate the effects of the health insurance exchange and Medicaid coverage expansions on hospital inpatient and emergency department (ED) utilization rates, cost, and patient illness severity, and also to test the association between changes in outcomes and the size of the uninsured population eligible for coverage in states.

DATA SOURCES:

Healthcare Cost and Utilization Project State Inpatient and Emergency Department Databases, 2011-2015, Nielsen Demographic Data, and the American Community Survey.

STUDY DESIGN:

Retrospective study using fixed-effects regression to estimate the effects in expansion and nonexpansion states by age/sex demographic groups.

FINDINGS:

In Medicaid expansion states, rates of uninsured inpatient discharges and ED visits fell sharply in many demographic groups. For example, uninsured inpatient discharge rates across groups, except young females, decreased by ≥39 percent per capita on average in expansion states. In nonexpansion states, uninsured utilization rates remained unchanged or increased slightly (0-9.2 percent). Changes in all-payer and private insurance rates were more muted. Changes in inpatient costs per discharge were negative, and all-payer inpatient costs per discharge declined <6 percent in most age/sex groups. The size of the uninsured population eligible for coverage was strongly associated with changes in outcomes. For example, among males aged 35-54 years in expansion states, there was a 0.793 percent decrease in the uninsured discharge rate per unit increase in the coverage expansion ratio (the ratio of the size of the population eligible for coverage to the size of the previously covered population within an age/sex/payer/geographic group).

CONCLUSIONS:

Significant shifts in cost per discharge and patient severity were consistent with selective take-up of insurance. The "treatment intensity" of expansions may be useful for anticipating future effects.
