Objective: To investigate the guiding significance of Daping orthopedics operative risk scoring system for senile patient (DORSSSP) for stratified treatment of elderly patients with severe hip fractures. Methods: A retrospectively case-control study was performed for data of 440 elderly patients with hip fracture admitted to Second Affiliated Hospital of Soochow University from January 2014 to January 2018, including 130 male and 310 female patients aged 60-98 years [(79.3±6.3)years]. According to the DORSSSP scoring system, the patients were divided into low risk group (Group A, n=208), medium risk group (Group B, n=157) and high risk group without SICU transfer after operation (Group C, n=23) and high risk group with SICU transfer after operation (Group D, n=52). The risk prediction results of each group were recorded and compared with the actual complications and mortality. Results: (1)According to the prediction of DORSSSP, the number of postoperative complications in Groups A, B, C and D were 52, 60, 14 and 31, respectively, while the number of actual complications after operation was 45, 55, 13 and 16. There was significant difference between the predicted value and the actual value of postoperative complications in Group D (P<0.01), which was not found in other three groups (P>0.05). The incidence of postoperative complications in Group D was lower than that in Group C (P<0.05). (2) According to the prediction of DORSSSP, the number of postoperative death in Groups A, B, C and D were 0, three, two and four, respectively, while the number of actual death after operation was 0, one, two and one, respectively. The predicted value and the actual value of death were significantly different in Group D (P<0.05), but were not in other three groups (P>0.05). The incidence of postoperative death in Group D was lower than that in Group C (P>0.05). Conclusions There is a good correlation between DORSSSP score and postoperative complications and mortality. Based on DORSSSP score for stratified treatment, the interventional treatment of elderly patients with severe hip fracture after operation into SICU can better reduce the incidence of complications.
