Occupational therapy improves social participation of complex patients discharged from hospital: results of a powered randomized controlled trial

Purpose To verify the effectiveness of experimental occupational therapy plus intensive standard rehabilitation compared to intensive standard rehabilitation alone on the reintegration to social activities of complex patients three months after hospital discharge.Materials and methods Patients with a score ≥ 9 on the Rehabilitation Complexity Scale at admission to an intensive rehabilitation ward were randomized to the control or experimental group. Both groups received intensive multidisciplinary rehabilitation aimed at recovering independence in the basic activities of daily life (ADL). The experimental group also received experimental occupational therapy services to address goals identified through the administration of the Canadian Occupational Performance Measure (COPM). Experimental occupational therapy began during the in-hospital phase and continued in the home-based setting. It consisted of teaching strategies, recommending aids, and providing personalized information regarding available community support.Results Ninety-two individuals with a mean age of 65 years (female 44.6%) were enrolled. The experimental group significantly improved participation measured by the Reintegration to Normal Living Index (mean changes 8.61, 95% CI: 1–16.23, p = 0.027). The performance and satisfaction scores of the COPM, both during hospitalization and after discharge, and independence in ADL also improved. No differences in mood disturbances were found.Conclusion Early post-discharge occupational therapy integrated with multidisciplinary rehabilitation improves the social participation of complex patients. Future research should investigate the concrete feasibility of implementing this complex intervention cost-effectively and in different contexts.Trial registration ClinicalTrials.gov Identifier NCT03668938 (first posted date 13/09/2018)
