Abstract

BACKGROUND: Safety in cardiac surgical procedures is predicated on effective team dynamics. This study associated operative team familiarity (ie, the extent of clinical collaboration among surgical team members) with procedural efficiency and Society of Thoracic Surgeons (STS) adjudicated patient outcomes.

METHODS: Institutional STS adult cardiac surgery registry and electronic health record data from 2014 to 2021 were evaluated across 3 quaternary hospitals. Team familiarity was defined as the mean number of cardiac operations performed by surgeon-anesthesiologist, surgeon-perfusionist, and anesthesiologist-perfusionist dyads within 1 year of the operation. The primary outcomes were (1) safety, measured by the STS' composite major morbidity and operative mortality measure, and (2) procedural efficiency, assessed by cardiopulmonary bypass duration. Team familiarity was stratified by terciles (low, moderate, and high) for crude analyses and analyzed continuously for adjusted analyses. Multivariable logistic and linear regression models were used to assess the association between team familiarity and outcomes.

RESULTS: Team familiarity was calculated for 13 581 operations. The median (interquartile range) patient age was 64 (55-72) years, and 31.9% (4328/13 581) were women. Terciles of team familiarity were defined as low (<6.00 average shared operations), moderate (6.00-9.67), and high (>9.67). Teams in lower terciles had higher observed STS morbidity and mortality rates (low, 17.9%; moderate, 18.0%; high, 16.0%; P=0.02) and longer median cardiopulmonary bypass duration (low, 137 minutes; moderate, 131 minutes; high, 118 minutes; P<0.001). After risk adjustment, team familiarity was not significantly associated with STS morbidity and mortality (estimate, -0.001 [95% CI, -0.998 to 0.997]) but was inversely associated with cardiopulmonary bypass duration (estimate, -2.02 minutes per 1 unit increase in team familiarity [95% CI, -2.30 to -1.75]).

CONCLUSIONS: Increased team familiarity was not associated with STS morbidity and mortality but was inversely correlated with cardiopulmonary bypass duration, demonstrating potential benefit. Interventions aimed at improving team familiarity among operative teams may increase procedural efficiency.
