Variation and Drivers of Costs for Emergency Department Visits Among Children in 8 States.
Article in Hospital pediatrics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 describe variation in costs for emergency department (ED) visits among children and to assess hospital and regional factors associated with costs.
methodsCross-sectional study of all ED encounters among children under 18 years in 8 states from 2014 to 2018. The primary outcome was each hospital's mean inflation-adjusted ED costs. We evaluated variability in costs between hospitals and determined factors associated with costs using hierarchical linear models at the state, region, and hospital levels. Models adjusted for pediatric case mix, regional wages, Medicaid share, trauma status, critical access status, ownership, and market competitiveness.
resultsWe analyzed 22.9 million ED encounters across 713 hospitals. The median ED-level cost was $269 (range 99-1863). There was a 5.1-fold difference in median ED-level costs between the lowest- and highest-cost regions (range 119-605). ED-level costs were associated with case mix index (+38% per 10% increase, 95% confidence interval [CI] 30 to 47); wages [+7% per 10% increase, 95% CI 5 to 9]); critical access (adjusted costs, +24%, 95% CI 13 to 35); for profit status (-20%, 95% CI -26 to -14) compared with nonprofit, lowest trauma designation (+17%, 95% CI 5 to 30); teaching hospital status (+7%, 95% CI 1 to 14); highest number of inpatient beds (+13%, 95% CI 4 to 23); and Medicaid share versus quarter (Q)1 (Q2: -12%, 95% CI -18 to -7; Q3: -13%, 95% CI -19 to -7; Q4: -11%, 95% CI -17 to -4).
conclusionsOur results suggest nonclinical factors are important drivers of pediatric health care costs.
