Aim We aimed to evaluate the factors contributing to delirium after hip fracture and assess the effect of incident delirium on short‐term clinical outcomes. Methods A total of 270 non‐delirious, consecutive hip fracture patients 60 years and older were included in a prospective cohort study. The patients were assessed with respect to physical status according to the American Society of Anesthesiologists classification, medical comorbidities with the Charlson Comorbidity Index, cognitive function with the Portable Mental Status Questionnaire and depression with the Geriatric Depressive Scale. Incident delirium was evaluated daily. Clinical outcomes and 1‐month mortality were recorded. Results Incident delirium was present in 53.0% of patients. Patients with delirium were older (P = 0.046), had higher American Society of Anesthesiologists and Charlson Comorbidity Index scores (P
