Development and validation of a postoperative risk calculator (POP-score) for patients undergoing cardiac surgery: a retrospective cohort study.

ABSTRACT:

Objectives

This study aimed to identify intraoperative and perioperative factors influencing 30-day mortality after cardiac surgery and to develop a risk score (POP-score) for its prediction.

Design

Retrospective cohort study with multivariable regression analysis.

Setting

A tertiary care cardiac surgery centre in Austria; data from consecutive patients undergoing cardiac surgery between 2010 and 2020 were analysed.

Participants

A total of 8072 patients were included. The cohort was randomly divided into a derivation cohort (75%) and a validation cohort (25%).

Outcome measures
