The incidence of hip fractures occurring at old age is gradually increasing. We analyzed he various factors affecting on the postoperative mortality of hip fractures for persons aging more than 65 years old. We hypothesized that the duration until surgery and the American Society of Anesthesiologists (ASA) classification were useful variables affecting on postoperative mortality rates. A retrospective review of 247 patients with hip fractures from January 2006 to June 2008 who had undergone operative treatment was performed. Overall postoperative one year mortality rate was 10.1%. The mortality rates who underwent surgery post injury for more than 3 days and less than 3 days were 11.7% and 5.9%, respectively. Higher mortality rates in ASA class 3 and 4 (9.7% and 22.2%, respectively) than in ASA class 2 (9.1%). In univariable analyses, sex and patients’ age at injury had statistical significances. In multivariable analyses, duration until surgery and ASA classification had strong correlation with postoperative mortality rate. Hip fractures in elderly patients should be fixed as early as possible. Patients with preoperative higher risk (in ASA class 3 or 4) should be closely managed and care must be taken following hip fracture surgery.
