Key result
The Perioperative Mortality risk score demonstrated good discrimination for 30-day postoperative mortality in older surgical patients, with a C-statistic of 0.80 (95% CI 0.74-0.86).
Why the study?
Does the Perioperative Mortality risk score accurately predict 30-day postoperative mortality in surgical patients aged 70 years or older?
Cohort (n=1,268)
Yes
Does the Perioperative Mortality risk score accurately predict 30-day postoperative mortality in surgical patients aged 70 years or older?
Effect estimate: C-statistic 0.80 (95% CI 0.74-0.86)
The Perioperative Mortality risk score, using six pre- and post-operative factors, demonstrates good discrimination and calibration for predicting 30-day postoperative mortality in older surgical patients.

May support risk stratification in older surgical patients; leaves open external validation before clinical adoption.
Story et al. (2009) conducted a cohort in Surgical patients (n=1,268). Perioperative Mortality risk score was evaluated on 30-day postoperative mortality (C-statistic 0.80, 95% CI 0.74-0.86). The Perioperative Mortality risk score demonstrated good discrimination for 30-day postoperative mortality in older surgical patients, with a C-statistic of 0.80 (95% CI 0.74-0.86).
