Abstract: Objective To retrospectively review the mortality and morbidity after orthopedic surgery for aged patients with reference to orthopedic version physiological and operative severity score for the enumeration of mortality and morbidity (O-POSSUM) and Portsmouth POSSUM (P-POSSUM) and validate the score' s accuracy in operative risk prediction.Methods O-POSSUM and P-POSSUM for mortality and morbidity were applied to 839 aged patients who had undergone orthopedic surgery between January 2008 and December 2011.Observed mortality and morbidity were compared with the expected values.Results O-POSSUM predicted 230 morbidities,but the observed value was 182 (x2 =2.718,P ＞ 0.05).O-POSSUM predicted 46 deaths,higher than the observed 3 deaths (x2 =38.870,P＜0.01).P-POSSUM predicted 16 deaths,higher than the observed 3 deaths (x2 =8.997,P ＜ 0.01).Conclusions O-POSSUM accurately predicts postoperative morbidity in aged orthopedic patients.However,O-POSSUM and P-POSSUM overpredicts the mortality and should be used with caution.
