Comparison of Surgical Risk Score, POSSUM and p-POSSUM in higher-risk surgical patients

摘要: Background: Much current interest is focused on the use of Physiological and Operative Severity Score for enUmeration Mortality morbidity (POSSUM) Portsmouth predictor equation (p-POSSUM) risk-adjusted surgical audit. The Surgical Risk (SRS) has been shown to offer an equivalent accuracy, but was validated using a cohort that contained high proportion low-risk patients. aim this study compare accuracy mortality prediction SRS with POSSUM p-POSSUM in higher-risk patients. Methods: Some 949 consecutive patients undergoing inpatient procedures district general hospital under care single surgeon were analysed. Results: The observed 30-day rate 8·4 per cent. Mean rates predicted SRS, scores 5·9, 12·6 7·3 cent respectively. No significant difference area receiver–operator characteristic curves three methods. Conclusion: The accurately equalled p-POSSUM.
