Key result
Age over 70 is linked to ~100% higher 30-day mortality after colorectal surgery.
Why the study?
Accurate prediction of postoperative mortality in elderly patients undergoing colorectal surgery is expected to improve preoperative decision-making.
Population
30,900 patients undergoing colorectal surgery including 10,750 elderly patients >70 years
Comparison
Elderly patients >70 years vs nonelderly patients <70 years
Design
Cohort study using National Surgical Quality Improvement Program database
Follow-up
30-day

May aid preoperative risk discussions in elderly colorectal patients; leaves open whether nomogram use improves decisions or outcomes.

A novel nomogram accurately predicts 30-day mortality in elderly patients undergoing colorectal surgery, which may facilitate preoperative decision-making.
Kiran et al. (2012) conducted a cohort in Colorectal surgery (n=30,900). Elderly age (>70 years) vs. Nonelderly age (<70 years) was evaluated on 30-day mortality (OR 2.0, 95% CI 1.7-2.4). Elderly age (>70 years) was associated with significantly higher 30-day mortality after colorectal surgery compared to nonelderly age (7.6% vs 2.0%; OR 2.0, 95% CI 1.7-2.4).
