A retrospective cohort study comparing outcomes following hip fractures in Australian indigenous patients with non-Australian indigenous patients.

AI patients with hip fractures were younger, had a higher Charlson Comorbidity Index Score and American Society of Anaesthesiologists grade, as well as a higher incidence of diabetes and associated end-organ sequalae. There was no difference in all-cause mortality. Odds of postoperative delirium was lower in the AI group. We did not find any difference in the length of hospital stay.
