Medicaid expansion associated with no change in emergency department use across racial and ethnic groups.
Article in Health services research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo estimate changes in the emergency department (ED) visit rate, hospitalization share of ED visits, and ED visit volumes associated with Medicaid expansion among Hispanic, Black, and White adults. DATA COLLECTION/EXTRACTION
methodsFor the population of adults aged 26-64 with no insurance or Medicaid coverage, we obtained census population and ED visit counts during 2010-2018 in nine expansion and five nonexpansion states. MAIN OUTCOMES AND MEASURES: The primary outcome was the annual number of ED visits per 100 adults ("ED rate"). The secondary outcomes were the share of ED visits leading to hospitalization, total number ("volumes") of all ED visits, ED visits leading to discharge ("treat-and-release") and ED visits leading to hospitalization ("transfer-to-inpatient"), and the share of the study population with Medicaid ("Medicaid share"). STUDY
designAn event-study difference in differences design that contrasts pre- versus post-expansion changes in outcomes in Medicaid expansion and nonexpansion states. PRINCIPAL
findingsIn 2013, the ED rate was 92.6, 34.4, and 59.2 ED visits among Black, Hispanic, and White adults, respectively. The expansion was associated with no change in ED rate in all three groups in each of the five post-expansion years. We found that expansion was associated with no change in the hospitalization share of ED visits and the volume of all ED visits, treat-and-release ED visits, and transfer-to-inpatient ED visits. The expansion was associated with an 11.7% annual increase (95% CI, 2.7%-21.2%) in the Medicaid share of Hispanic adults, but no significant change among Black adults (3.8%; 95% CI, -0.04% to 7.7%).
conclusionACA Medicaid expansion was associated with no changes in the rate of ED visits among Black, Hispanic, and White adults. Expanding Medicaid eligibility may not change ED use, including among Black and Hispanic subgroups.
