The risks of hip fracture in older people from private homes and institutions.

This study aimed to determine whether the incidence of hip fracture is greater among those living in institutions compared with those living in private homes. Over two and a half years of surveillance, 1832 hip fractures were identified, of which 58% were sustained by those living in private homes and 42% by those living in institutions. The risks of hip fracture, unadjusted for age and sex, were 10.5 times greater for those living in institutions compared with those living in private homes. After adjusting for age and sex, these greatly increased risks were maintained, although for both men and women the risks decreased with age, such that at ages over 90 years the risks were not significantly different. Given these findings, hip fracture prevention strategies that focus particularly on individuals within institutions are highly commended.
