Acuity of Patients Undergoing Congenital Heart Surgery During Hospitalization.
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
backgroundSince 2014, Complexity Assessment and Monitoring to Ensure Optimal Outcomes (CAMEO) acuity tools have guided pediatric critical care and acute nurse staffing decisions. Using these data, we constructed a cardiac intensive care postoperative timeline, the CAMEO Acuity Curve, for 3 congenital heart surgery procedures. We now expand both procedures and timeline to comprehensively describe patient acuity during hospitalization.
methodsWe reviewed 5 common congenital heart procedures between November 2018 and December 2023-Stage I palliation for single ventricle, arterial switch operation for dextro transposition of great arteries with or without ventricular septal defect repair, tetralogy of Fallot repair, ventricular septal defect repair, and atrial septal defect repair. CAMEO scores from cardiac intensive care unit admission through discharge were abstracted to create procedure-specific CAMEO Acuity Curves. Data were also stratified by severity of residual lesions in anatomic area of repair using the residual lesion score.
resultsAmong 574 cases, 72 (13%) were Stage I, 118 (20%) arterial switch operation repair, 144 (25%) tetralogy of Fallot repair, 159 (28%) ventricular septal defect repair, and 81 (14%) atrial septal defect repair. CAMEO scores varied in acuity by procedure. The highest mean acuity was for Stage I (116±6) and the lowest for atrial septal defect repair (94±9). Acuity increased for residual lesion score 3 compared with residual lesion score 1 and 2.
conclusionsCAMEO Acuity Curves for 5 postoperative congenital heart procedures illustrate expected periods of high acuity. This approach highlights variation by procedure, physiologic status, and hemodynamically significant residual lesions and may inform timely clinical decision-making, guide acuity-specific interprofessional staffing, facilitate throughput, and predict resource needs.
