COVID‐19 during the index hospital admission confers a ‘double‐hit’ effect on hip fracture patients and is associated with a two‐fold increase in 1‐year mortality risk

Purpose The aims were to: (1) determine 1‐year mortality rates for hip fracture patients during the first UK COVID‐19 wave, and (2) assess mortality risk associated with COVID‐19. Methods A nationwide multicentre cohort study was conducted of all patients presenting to 17 hospitals in March‐April 2020. Follow‐up data were collected one year after initial hip fracture (‘index’) admission, including: COVID‐19 status, readmissions, mortality, and cause of death. Results Data were available for 788/833 (94.6%) patients. One‐year mortality was 242/788 (30.7%), and the prevalence of COVID‐19 within 365 days of admission was 142/788 (18.0%). One‐year mortality was higher for patients with COVID‐19 (46.5% vs. 27.2%; p
