Differences in Postoperative Atrial Fibrillation Incidence and Outcomes After Cardiac Surgery According to Assessment Method and Definition: A Systematic Review and Meta-Analysis.

BACKGROUND: Postoperative atrial fibrillation (POAF) is the most frequent complication of cardiac surgery. Despite clinical and economic implications, ample variability in POAF assessment method and definition exist across studies. We performed a study-level meta-analysis to evaluate the influence of POAF assessment method and definition on its incidence and association with clinical outcomes. METHODS AND RESULTS: A systematic literature search was conducted to identify studies comparing the outcomes of patients with and without POAF after cardiac surgery that also reported POAF assessment method. The primary outcome was POAF incidence. The secondary outcomes were in-hospital mortality, stroke, intensive care unit length of stay, and postoperative length of stay. Fifty-nine studies totaling 197 774 patients were included. POAF cumulative incidence was 26% (range: 7.3%-53.1%). There were no differences in POAF incidence among assessment methods (27%, [range: 7.3%-53.1%] for continuous telemetry, 27% [range: 7.9%-50%] for telemetry plus daily ECG, and 19% [range: 7.8%-42.4%] for daily ECG only; P>0.05 for all comparisons). No differences in in-hospital mortality, stroke, intensive care unit length of stay, and postoperative length of stay were found between assessment methods. No differences in POAF incidence or any other outcomes were found between POAF definitions. Continuous telemetry and telemetry plus daily ECG were associated with higher POAF incidence compared with daily ECG in studies including only patients undergoing isolated coronary artery bypass grafting. CONCLUSIONS: POAF incidence after cardiac surgery remains high, and detection rates are variable among studies. POAF incidence and its association with adverse outcomes are not influenced by the assessment method and definition used, except in patients undergoing isolated coronary artery bypass grafting.

Predictors of premature termination and completion of randomized controlled trials.

Randomized clinical trials (RCTs) have a key role in progressing biomedical research and guiding clinical decision making, but premature termination remains high (up to 30%), raising concerns regarding funding expenditure and resource allocation. This brief report sought to identify variables associated with RCTs' premature termination and completion.

Active antiracism through surgical education.

INTRODUCTION: Disparities in surgical outcomes are well documented. Racial/ethnic minorities are also disproportionately underrepresentated in surgery; however, most surgeons do not acknowledge the existence of disparities. Diversity, equity, and inclusion (DEI) education in surgery is needed, yet DEI education is often confined to designated diversity lectures, limiting depth of content. Underrepresented minorities (URMs) are also more likely to be tasked with leading DEI initiatives, perpetuating the minority tax and limiting non-URM engagement. METHODS: A DEI curriculum was implemented in a general surgery department, inclusive of programming at morbidity and mortality (M&M) and grand rounds (GR). RESULTS/LESSONS LEARNED: After implementing a DEI curriculum there was a significant increase in DEI topics at M&M (0% versus 27.3%; p < 0.01) and GR (0% versus 18.4%; p < 0.001). The majority of DEI M&Ms were presented by non-URMs (88.89%). Most DEI GR were presented by URMs (55%). CONCLUSIONS: Structured integration of DEI initiatives into surgery department conferences may serve as a practical approach to increasing departmental awareness of disparities, expanding DEI engagement, and increasing academic recognition for DEI initiatives.
