Balancing quality and quaternary care imperative using a high-risk case review committee in adults.
Article in Interactive cardiovascular and thoracic surgery, 2022. 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
objectivesQuaternary care centres have an imperative to serve as hospitals of last resort and must also meet professional quality targets. We developed a high-risk committee (HRC) to evaluate cases meeting pre-defined predicted risk cut-offs as a part of an overall quality improvement drive.
methodsWe describe the structure, outcomes and effects of the Penn HRC. Using propensity-matching, we investigated whether the committee modifies or screens risk. We used multivariable analysis to examine the impact of unmeasured variables on clinical outcomes in this cohort.
resultsInstitutional predicted and observed mortality had already been in decline prior to HRC institution in 2017, due to a multi-faceted quality improvement initiative. Between 2017 and 2020, the HRC discussed 205 patients with a median predicted risk of mortality of 10.6% (range 0.4-66%). Coronary artery bypass grafting was the most commonly presented operation. A total of 155 patients underwent operation (risk 10.3%), 12 had surgery deferred for optimization (risk 6%), 50 had surgery declined (risk 11.7%) and 12 patients had a deferred decision for further investigation. Overall 30-day survival was 86% for the entire cohort and 89% for operated patients. A matched analysis of similar patients prior to and following the HRC showed that the HRC did not directly modify outcomes. Most patients had better than expected survival (observed:expected mortality < 1). Predicted risk did not predict 30-day mortality among this high-risk cohort.
conclusionsHRCs serve as an important element in quality improvement by encouraging a thoughtful approach and channelling the collective experience of a group of senior surgeons. It may improve patient selection by identifying a cohort with extremely poor survival, while allowing safe operation with acceptable outcomes among a group with very high operative risk.
