Summary
Some patients die after major surgery. Risk prediction tools can help shared decision making with the patient, aiding decisions on whether to operate, how to prepare and use of critical care.
An international multi-centre prospective observational cohort study in 274 sites with 22,631 patients compared risk prediction with 30-day mortality. In 88.7% of cases clinicians exclusively used subjective assessment. The best predictions were from the SORT tool combined with clinical assessment. P-POSSUM Surgical Risk Scale, SRS and SORT all over-predicted risk, with SORT performing best.
This 10-question SORT model has been updated including clinician assessment and provides an accurate means of predicting perioperative risk.
