Background. The prevalence of hip fractures is steadily increasing, as the population ages. These fractures are associated with significant morbidity and mortality. Most of these fractures are treated surgically. Factors related to surgical intervention can play a significant role in the outcome.
This study examines the association of in-hospital mortality with the timing of surgery, sex, and age of patients treated surgically due to a hip fracture at Clinical Hospital Shtip in a 2-year long period.
Material and Methods. A total of 348 patients admitted with a diagnosis of hip fracture who were treated surgically were identified. Data about sex and age were collected. The outcome was assessed for groups treated within 24, 48, 72, and more than 72 hours after admission. Descriptive statistical methods, chi-square test, t-test for independent samples, and odds - ratio with 95% confidence interval (CI) were used in statistical analysis.
Results. The delay of surgical treatment beyond 24 hours did not increase the risk of death (OR=0.65, 95%CI=0.23-1.73). Delays beyond 48h and 72h increased the risk of death progressively (OR=1.17, 95%CI=0.50-2.75, and OR=1.65, 95%CI=0.69-3.95 respectively). Mortality was significantly higher in the 76-85-years age group.
Conclusions. Association between surgical delay and in-hospital mortality in hip fracture patients is disputed. Confounding factors such as age, sex, comorbidities, and type of treatment determine the outcome. Patients with hip fractures, without any additional disease, should be operated on as soon as possible after admission to the hospital. Delay beyond 48 hours may increase the risk for in-hospital mortality.
