Objectives : This study aimed to determine the risk factors that increase the risk of in-hospital mortality and/or prolonged hospital stay in hip fracture patients aged over 65 years. Methods : We conducted a retrospective study of patients aged over 65 years who underwent hip fracture surgery in the period from January 2015 to December 2017. Our analysis included 54 variables related to medical, psychological, functional and laboratory comorbidities present at admission; treatment, complications and laboratory follow-up during the hospital stay; and functional status and destination on discharge. We performed a bivariate analysis and a multivariate analysis with a composite endpoint combining in-hospital mortality and hospital stay lasting more than 10 days. Results : We included 360 patients with an average age of 84 years. Women accounted for 75% of the sample, and 53.5% of all patients had a pertrochanteric fracture. The mean number of comorbidities per patient was 2.72, and the most common comorbidities were high blood pressure, dementia and diabetes. The rate of in-hospital mortality was 3.6% (n 13) and the mean length of hospital stay was 8.48 days, with 16.4% of patients staying in hospital for more than 10 days. Medical complications, lower hemoglobin on admission, high blood pressure, obesity and Parkinson’s disease were significantly associated with our endpoint in the multivariate analysis Conclusions : Patients who suffer medical complications during hospitalization, and those with lower hemoglobin on admission, high blood pressure, obesity or Parkinson’s disease, have an increased risk of in-hospital mortality or prolonged hospital stay |
