The following prognostic factors were evaluated: age, gender, comorbidities, location of second hip fracture, type of surgical intervention, complication after second hip fracture, and day of hospital admission were studied. The 30 day mortality was calculated for each group. Predictors for 30 day survival were evaluated by Kaplan-Meier survival analysis and log-rank test. Statistical analyses were performed using the SPSS version 19.0. RESULTS:
