Center Volume and Failure to Rescue in Pediatric Cardiac Surgery: Is There a Relationship?
Article in The Annals of thoracic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundFailure to rescue (FTR) is a validated quality metric for evaluating outcomes in pediatric cardiac surgery. Using a national administrative database, we sought to assess the relationship between annual hospital case volume and FTR.
methodsCardiopulmonary bypass (CPB) cases were extracted from the Kids' Inpatient Database for 2016 and 2019. FTR was defined as inpatient mortality of patients with at least 1 postoperative complication. Hospitals were divided into high-, mid-, and low-volume hospitals on the basis of annual CPB case volume terciles. A mixed effects multivariable logistic model was created to evaluate the association of annual CPB case volume and FTR. By use of the mean adjusted FTR rate of the entire sample as the benchmark, hospitals were divided into underperformers and overperformers.
resultsA total of 10,528 patients had 1 or more complications during the same admission. There were 134 hospitals in the low-volume group, 64 in the mid-volume group, and 31 in the high-volume group. The risk-adjusted FTR rate was 4.04% for the entire cohort. Compared with low-volume hospitals at baseline, there was no statistically significant difference in FTR for mid-volume hospitals (odds ratio, 0.8; 95% CI, 0.61-1.1; P = .184) or high-volume hospitals (odds ratio, 0.8; 95% CI, 0.6-1.1; P = .201). There were underperforming and overperforming hospitals in all volume groups.
conclusionsThis real-world contemporary analysis highlights that hospital volume is not associated with FTR after pediatric cardiac surgery. Underperformers and overperformers exist in all volume groups. Volume may not be a reliable quality metric for comparing outcomes in pediatric cardiac surgery.
