Risk factor analysis and nomogram model of DVT in hip fracture patients at hospital admission.

Background: The incidence of deep vein thrombosis (DVT) on the first day of hospitalization in patients with hip fractures is as high as 42%, significantly impacting perioperative safety and, in severe cases, leading to patient mortality. This study aims to develop a diagnostic model based on the available demographic variables, comorbidities, and laboratory test results at admission in patients with hip fractures, and to evaluate its diagnostic performance.

Methods: This study retrospectively collected clinical data from 238 patients with hip fractures admitted to the Third Affiliated Hospital of Chongqing Medical University between January 2019 and December 2021.
