Refining surgical risk assessment: the importance of separating cardiac and non-cardiac surgical cohorts

Key Points

• To evaluate the impact of separating cardiac and non-cardiac surgical cohorts on surgical risk assessment.
• Evaluated surgical risk assessments in distinct cardiac and non-cardiac cohorts.
• Used statistical analysis to compare complication rates and outcomes.
• Developed and validated predictive models for each surgical group.
• Separation of cohorts improved the accuracy of risk assessment models.
• Cardiac surgery showed a 15% higher complication rate (RR 1.15, 95% CI 1.05-1.27, P=0.02).
• Overall outcomes were significantly better predicted when cohorts were analyzed separately.
