Abstract

Abstract: Background: To maximise the benefits of hip fracture surgery the National Institute for Health and Care Excellence Clinical Guideline recommends mobilisation on the day after hip fracture surgery based a low to moderate quality trial with a small sample size. There is a need to generate additional evidence to support early mobilisation as a new UK Best Practice Tariff (BPT). Objective: To determine whether mobilisation timing was associated with the cumulative incidence of hospital discharge by 30-days after hip fracture surgery, accounting for potential confounders and the competing risk of in-hospital death. Method: We examined data for 135, 105 patients 60 years or older who underwent surgery for nonpathological first hip fracture between January 2014 and December 2016 in any hospital in England or Wales. We tested whether the cumulative incidences of discharge differed between those mobilised early (within 36 hours of surgery) and those mobilised late accounting for potential confounders and the competing risk of in-hospital death. Results: 106, 722 (79%) of patients first mobilised early. The average rate of discharge was 60.1 (95% CI 59.8–60.5) per 1, 000 patient days, varying from 65.2 (95% CI 64.8–65.6) among those who mobilised early to 44.5 (95% CI 43.9–45.1) among those who mobilised late, accounting for the competing risk of death. By 30-days postoperatively, the crude and adjusted odds ratios of discharge were 2.26 (95% CI 2.2–2.32) and 1.93 (95% CI 1.86–1.99) respectively among those who first mobilised early compared to those who mobilised late, accounting for the competing risk of death. Conclusion: Early mobilisation led to a near two fold increase in the adjusted odds of discharge by 30-days postoperatively. We recommend inclusion of mobilisation within 36 hours of surgery as a new UK BPT to help reduce delays to mobilisation currently experienced by one-fifth of patients surgically treated for hip fracture.
