Background: A comprehensive team approach for increasing stay away from bed time (SaB-time) called CASaB was conducted at multiple rehabilitation hospitals.
Aims: The aim of the present study was to investigate the association between SaB-time and clinical rehabilitation outcomes (CROs) before introducing CASaB (observational phase), and comparing CROs before and after CASaB (CASaB phase).
Methods: This prospective observational study included patients who were admitted to nine rehabilitation hospitals, with complete data. The final analysis included 197/229 patients in the observation phase, and 229/256 patients in the CASaB phase. We first tested whether SaB-time was positively associated with CROs in an observational study, then compared CROs before and after CASaB.
Results: In the observation phase, longer SaB-time was significantly associated with greater rehabilitation efficiency (REy) after adjusting for confounders (standardized β = 0.20, p = 0.007). In a comparison of CROs before and after CASaB, the length of hospital stay during the CASaB phase was significantly shorter than during the observational phase (61.5, 57.6-65.4 days vs 75.6, 71.4-79.9 days, p < 0.001), and the REy after CASaB was significantly greater than that before the CASaB (0.38, 0.33-0.42/day vs 0.28, 0.25-0.33/day, p = 0.006).
Discussion: The current results suggest that increasing SaB-time may help the recovery of functional abilities, particularly for patients in rehabilitation hospitals.
Conclusions: The CASaB provides a method for improving the recovery efficiency of patients in rehabilitation hospitals.
