Is the mortality higher in patients who have suffered a hip fracture?

Abstract

Background and objective: The aim of this study is to value whether patients who have suffered a hip fracture have a higher mortality than expected.

Material and methods: A prospective, observational study was carried out where patients with hip fracture were collected as a sample over a year. The study included 284 patients and a minimum follow-up was 2 years. The mean age of these patients was 84.26 years, with 21.48% (61/284) males and 78.5% (223/284) females. Survival and previous diseases that affect mortality, as risk factors, were collected and analyzed using the Kaplan-Meier method and the Cox regression model. Actual mortality was compared with that expected according to the Charlson Comorbidity Index, adjusted for age.

Results: Previous pathology was the main mortality factor, with heart disease being the most significant (OR 1.817, CI95%: 1.048; 3.149). The real mortality at one year of the sample was 22.5%, while the estimated annual mortality according to the Charlson Comorbidity Index was 29.68% (CI95%:44,36-15).

Conclusions: Hip fracture does not cause an increase in mortality according to the Charlson Comorbidity Index estimate.
