[Analysis of rising treatment cost of elevated BMI in patients with proximal femoral fracture].

Driven by the aging population, the proximal femoral fracture is a rising fracture entity, challenging trauma surgeons as well as the German healthcare system as a whole. The rising average age of the population is accompanied by a rising BMI in the German population, resulting in longer operation times, longer average length of stay (ALOS) as well as more postoperative complications.The aim of this study was to demonstrate the economic correlation between body mass index and hospital costs. The retrospective analysis of 950 patient cases suffering from a proximal femoral fracture resulted in the finding of rising treatment costs being positively associated with rising BMI due to longer operation times and longer length of hospitalization (10,452 €, 11,505 €, 12,085 € and 13,681 € for patients with BMI < 18.5 kg/m, BMI = 18.5-24.9 kg/m, BMI = 25.0-29.9 kg/m and BMI ≥ 30.0 kg/m, respectively).
