INTRODUCTION: The increase in life expectancy and the aging population have led to a higher incidence of hip fractures, especially in women over 60 years old. This study analyzes the influence of a multidisciplinary team with the collaboration of a specialist in internal medicine (IM) with the trauma department on mortality, perioperative complications and hospital stay in patients with hip fractures. MATERIAL Y METHODS: An analytical observational study of historical cohorts was conducted in patients over 65 years admitted for hip fracture and treated with arthroplasty or intramedullary nailing. Two cohorts were established: one before and one after the IM assignment. Patients with metabolic bone diseases different from osteoporosis and those who were operated in other centers were excluded. The minimum follow-up was 12 months. RESULTS: A total of 190 patients (50 men, 140 women) were included, with a mean age of 82.0 years and a BMI of 27.5. Mortality, which was the main objective of our study, during the first 12 months was higher in the non-IM (27.1% vs. 13.5%
p=0.035). In addition, we included systemic complications and hospital stay as secondary objectives. Systemic complications were also higher in the non-IM cohort (43.2% vs. 27.1%
p=0.031). Overall hospital stay was shorter in the IM cohort (7.3 days vs. 9.9 days
p=0.001). ''Preoperative stays shorter than 72 hours'' were more frequent in the IM group (53.0% vs. 33.2%
p=0.009). CONCLUSIONS: Multidisciplinary collaboration with a specialist in internal medicine significantly reduces first-year mortality, systemic complications, and hospital stay in hip fracture patients, allowing earlier interventions and hospital discharge.
