Discharge Barriers and Length of Stay Following Congenital Heart Surgery: A Mixed-Methods Approach.
Article in Journal of the American Heart Association, 2026. 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
backgroundThis study aimed to identify granular discharge barriers after congenital heart surgery and compare the contributions of discharge barriers versus clinical factors to postoperative length of stay (LOS) variation among infants with severe congenital heart defects.
methodsThis was a retrospective cohort study of patients who underwent initial cardiac surgery at ≤12 months, from 2015 to 2021, at a high-volume congenital heart defect surgical center. The outcome was postoperative LOS. The exposure was discharge barrier category, a 7-level categorical variable determined a priori using a mixed-methods approach. Covariates included surgical/anatomic complexity, postoperative complications, sociodemographics, and comorbidities. Associations between discharge barrier categories and postoperative LOS were estimated with log-linear models. A Shorrocks-Shapley decomposition estimated each covariate's contribution to outcome variation.
resultsA total of 752 infants met the inclusion criteria; 24.3% experienced a discharge barrier. The most common discharge barrier category was medical equipment delivery or prior authorization delays (52/752, 6.9%). Median postoperative LOS for those without and with barriers was 8 (interquartile range, 5-15) and 26 (interquartile range, 14-52) days, respectively (
conclusionsDischarge barriers are as influential as surgical and anatomic complexity in explaining variation in postoperative LOS among infants undergoing congenital heart surgery. Future research and clinical efforts to mitigate modifiable discharge barriers may yield improvements in postoperative LOS.
