Key summary points
To investigate the association between additional weekend rehabilitation and functional outcomes among different age groups.
AbstractSection FindingsAfter matching 129,583 pairs of cases, a significantly higher correlation was found between patients who had received weekend rehabilitation and improved physical function at discharge compared with those who had not received weekend regarding function in transferring, walking, and stair climbing at discharge, as compared with patients who did not (odds ratio [95% confidence interval]: 1.17 [1.15–1.19], 1.17 [1.15–1.2], and 1.06 [1.03–1.08], respectively).
AbstractSection MessageWeekend rehabilitation was significantly associated with improved physical function; to optimise rehabilitation therapy given limited healthcare resources, low demand activities can be more effective in older age groups, whereas high demand activities should be aimed at younger age groups.
Abstract
Purpose
Rehabilitation after hip fracture surgery is crucial for improving physical function. Additional rehabilitation over the weekend or after working hours is reportedly associated with improved physical function; however, this may not apply to an aging population, including patients aged > 90 years. This study aimed to investigate the association between additional weekend rehabilitation and functional outcomes in different age groups.
Methods
This study analyzed a cohort of patients aged ≥ 60 years who had hip fractures and were operated on from 2010 to 2018. Data were extracted from a nationwide multicentre database. Functional outcomes at discharge were compared between patients who underwent rehabilitation on weekdays only and those who underwent rehabilitation on both weekdays and weekends. The patient groups were selected using propensity score matching analysis. Furthermore, a subgroup-analysis was conducted on patients in their 60 s, 70 s, 80 s, and 90 s.
Results
A total of 390,713 patients underwent surgery during the study period. After matching, each group comprised 129,583 pairs of patients. Patients who underwent weekend rehabilitation exhibited improved physical function in transferring, walking, and stair climbing at discharge, as compared with patients who did not (odds ratio [95% confidence interval]: 1.17 [1.15–1.19], 1.17 [1.15–1.2], and 1.06 [1.03–1.08], respectively). In subgroup analysis, except for stair climbing, the positive association between weekend rehabilitation and patient function was observed across all age groups.
Conclusion
Weekend rehabilitation was significantly associated with improved physical function. Given the limited healthcare resources, high-demand activities such as stair climbing may be reserved for younger age groups to optimise rehabilitation therapy.
