Öztürk B, et al. - Researchers analyzed the link between surgery delay and mortality in hip fracture patients with and without known comorbidity. This study included all patients with a first time hip fracture diagnose operated between January 1, 2010 and December 31, 2015 (n = 36,552). Using Charlson Comorbidity Index stratified in categories: none (no registered comorbidities prior fracture), medium (1-2 points) and high (> = 3 points), they assessed comorbidity. Findings revealed that hip fracture surgery patients with none and medium level of comorbidity demonstrated a link between surgery delay and 30-days mortality, whereas those with a high comorbidity level exhibited no such association. In both patients with and without comorbidity prior surgery, they found an association between surgery delay and one year increased risk of dying.
