TIMELY MUNICIPALITY REHABILITATION AFTER HOSPITALISATION REDUCES READMISSION AND EARLY MORTALITY.

Objective: Firstly, the study explores the association between timely initiation of rehabilitation and 90-day and 365-day all-cause acute readmission and secondly, 90-day and 365-day all-cause mortality in a cohort of Odense Municipality residents. Methods: The registry-based observational cohort study investigates acute contacts at Odense University Hospital from 2015 to 2020. Descriptive statistics, Cox regression and cumulative incidence rates were used for analysis. Subjects: The study utilizes initiated rehabilitation referrals within 60 days from Odense Municipality residents. Results: In total, 7,377 rehabilitation plans were initiated, including 5051 (68.5%) within the legal timeframe. Overall, timely initiation of rehabilitation within the legal timeframe was associated with a significantly reduced risk of 90-day all-cause acute readmission (Adjusted HR 0.82, 95% CI 0.74-0.90).In the adjusted analysis, timely initiation was also significantly associated with reduced risk in 365-day all-cause acute readmission (HR 0.90, 95% CI 0.83-0.97). Each week of delay in initiation of rehabilitation was associated with an increased risk of readmission (HR 1.05, 95% CI 1.02-1.07). Further, timely initiation of rehabilitation was associated with a significant reduction in the risk of 365-day all-cause mortality (HR 0.74, 95% CI 0.61-0.89). Conclusion: Timely initiation of rehabilitation within the legal timeframe of 7 or 14 days was associated with significantly reduced risk of 90-day and 365-day all-cause acute readmission. Timely initiation of rehabilitation was also associated with significant reduction in the risk of 365-day all-cause mortality.
