Abstract：Objective To explore the predictive effects of the physiological and operative severity score for the enumeration of mortality and morbidity ( POSSUM ) and its Portsmouth modification ( P-POSSUM ) on the complication and mortality rates after hip fracture surgery. Methods The study was conducted in 92 patients with hip fractures treated in our hospital from January 2013 to December 2015. The POSSUM and P-POSSUM scoring systems were used to predict the postoperative complication and mortality rates, which were then compared with the actual complication and mortality rates. Results Postoperative complications occurred in 27 of 92 cases, among whom 5 cases had 2 kinds of complications and 1 case died. The rate of surgical complications was 29.35%, and the mortality rate was 1.09%. According to the POSSUM scoring system, 31 of 92 cases were predicted to have postoperative complications ( 33.70% ), and the differences were not statistically significant when compared with 27 cases with actual complications ( 29.35% ) ( P > 0.05 ). According to the POSSUM scoring system, the predicted mortality rate was 8.70% in 8 of 92 cases, which was higher than the actual mortality rate 1.09% in 1 case, and the differences were statistically significant ( P < 0.05 ). According to the P-POSSUM scoring system, the predicted mortality rate was 3.26% in 3 of 92 cases, and the differences were not statistically significant when compared with the actual mortality rate 1.09% in 1 case ( P > 0.05 ). Conclusions The POSSUM scoring system to predict postoperative complications in hip fracture patients has a high clinical value, and the P-POSSUM scoring system also has a high clinical value in predicting the mortality rate after hip fracture surgery.
