Abstract:

BACKGROUND: It is important to predict the risks of arthroplasties before operation. Among the systems of prediction of morbidity and mortality, POSSUM and P-POSSUM scores have been proved to be the most reliable scoring systems. However, its application in arthroplasties is rarely reported.
OBJECTIVE: To evaluate the value of POSSUM and P-POSSUM scores in predicting morbidity and mortality in patients undergoing arthroplasties．
METHODS: From 2008-01 to 2010-10, 186 patients underwent arthroplasties were studied retrospectively using POSSUM and P-POSSUM scoring systems to predict the morbidity and mortality.
RESULTS AND CONCLUSION: There was no statistically difference between the patients with complications predicted by POSSUM (32 cases, 17%) and the observed (28 cases, 15%) within 30 days after implantation (P > 0.05). The observed deaths number (5 cases, 3%) also had no significant difference from the predicted value by P-POSSUM (2 cases, 1%). POSSUM and P-POSSUM scoring systems showed satisfied predictive ability of morbidity and mortality.
