Length of hospital stay after hip fracture and short term risk of death after discharge: a total cohort study in Sweden

Objective To investigate relation between inpatient length of stay after hip fracture and risk of death after hospital discharge. Setting Population ≥50 years old living in Sweden as of 31 December 2005 with a first hip fracture the years 2006-12. Participants 116 111 patients with an incident hip fracture from a closed nationwide cohort. Main outcome measure Death within 30 days of hospital discharge in relation to hospital length of stay after adjustment for multiple covariates. Results Mean inpatient length of stay after a hip fracture decreased from 14.2 days in 2006 to 11.6 days in 2012 (PLimitations No accurate evaluation of the underlying cause of death could be performed. Conclusion Shorter length of stay in hospital after hip fracture is associated with increased risk of death after hospital discharge, but only among patients with length of stay of 10 days or less. This association remained robust over consecutive years.
