ABSTRACT
Objective To evaluate the value of the physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) and P-POSSUM in predicting the risks of orthopedic surgeries for senile patients with femoral neck fracture.Methods A total of 108 patients with femoral neck fractures who underwent hip joint replacement were retrospectively studied using POSSUM and P-POSSUM scoring system to predict their mortality and complication rate.The difference between predictive value and observed value was analyzed by chi-square test.Meanwhile,the patients were divided into two groups based on their POSSUM scores.The differences between two groups were analyzed.Results According to POSSUM scores,47 patients were predicted to have complications(the mean rate was 43.52%),but only 37 did actually (the rate was 34.26%).There was no significant difference between predicted values and observed values (P =0.238).The predicted death toll was 11 cases (the mean rate was 10.19%),but actually only 2 patients died (the rate was 1.85%).Predicted value was higher than observed value.In terms of complications,death toll agreed well with the predicted values calculated by P-POSSUM (predicted death of 4 cases' the mean mortality being 3.70% ; actual death of 2 cases' the mortality was 1.85%) without significant difference (P =0.625).We divided the patients into two groups with the POSSUM scores 40,and there was no significant difference between predicted values and observed values (P =0.527,P =0.285).Conclusions POSSUM has better predictive ability of morbidity,but overestimates mortality.P-POSSUM more accurately predicts mortality than POSSUM.The predicted results of POSSUM and P-POSSUM scoring systems are satisfactory in the high risk group.
