Impact of a statewide Emergency Department Information Exchange on health care use and expenditures.
Article in Health services research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 assess the effects of a program mandating the statewide adoption of an Emergency Department Information Exchange (EDIE) on health care utilization and spending among Medicaid enrollees in Washington state. DATA SOURCE: Medicaid claims and managed care encounters from the Washington Health Care Authority. STUDY
designA difference-in-differences analysis with trends was used to compare changes in ED visits, inpatient admissions, primary care visits, and expenditures among frequent ED users (≥5 ED visits in past year) to those of infrequent users through the second year Washington's program. DATA EXTRACTION: The study population included adult Medicaid enrollees with ED visits between January 2010 and October 2014. PRINCIPAL
findingsThere were 505,667 ED visits among 153,543 unique enrollees included in the analysis. Washington's program was associated with a small, but statistically significant differential change of -0.70 ED visits per enrollee per year (95% CI: -1.24, -0.16) in the first year after EDIE was mandated, or 8.2% of the baseline ED visit rate among frequent users. However, by the second year of implementation, these effects on ED use were no longer significant, nor were there any measurable effects on inpatient admissions, primary care use, or expenditures in any period.
conclusionsStatewide implementation of EDIE was associated with a small reduction in ED use among frequent users in the first year of the program but did not change overall spending or other utilization outcomes.
