[Prevalence investigation of severe pulmonary embolism in older patients with hip fracture].

Abstract

In the perioperative period, pulmonary embolism (PE) is common. PE severity is well defined, but its prevalence remains poorly understood in the hip fracture (HF) context; a surgery at high hemorrhagic risk. The main objective was to measure severe PE prevalence in the HF perioperative period in subjects aged over 75. This observational, monocentric, retrospective study was carried out in the orthogeriatric unit at Grenoble University Hospital, from January 1, 2020 to December 31, 2021. PE was considered severe if it was at an intermediate high risk or high risk of early death. The secondary objectives were to compare the characteristics of subjects with severe PE with those without severity criteria. Severe PE prevalence was 38.4% (15/39) or 4.8% (15/313) of the fractured population. Patients in the severe PE group were more likely to develop deep hematoma (33 % versus 4.2 %, p = 0.024), and required twice more transfusion of packed red blood cells (60 % versus 29 %, p 0.05). À combination of factors may explain why PE severity is linked to PE, but also to an increased risk of bleeding.
