Abstract WP34: Collaboration Between Acute Care Hospitals And Rehabilitation Hospitals Reduces 30-day Readmission And Mortality After Ischemic Stroke Hospital Discharge

Background: To improve transitions of care from an acute hospital to an acute rehabilitation hospital, monthly multidisciplinary case review meetings among these hospitals' staff were implemented in 2020. This study aimed to determine whether this effort improved the outcomes of stroke patients. Methods: Monthly online meetings among the acute stroke care team and 3 rehabilitation hospital team leaders were implemented in a large healthcare system. The goal of these meetings was to review all readmissions in-depth, promote communication, and establish best practice protocols to reduce adverse events. We compared patient outcomes before (2018-2019, n=360) and after (2020-2021, n=264) the intervention using multivariate logistic regression models. The primary outcomes were all-cause mortality and readmission within 30 days after acute hospital discharge. Secondary outcomes were 30-day mortality, readmission, and ED visits. The models were adjusted for patient demographics, comorbidities, stroke severity assessed with the National Institute of Health Stroke Scale (NIHSS), and hospital stroke certification status. Results: The median patient age was 70 (interquartile range [IQR]: 60;79), and 297 (48%) were females. The patients in the post-intervention period had longer hospital stays (median 6 vs. 5 days, p<.0001) and higher median NIHSS scores (6 vs. 4, p=0.03). The intervention was associated with lower 30-day all-cause mortality and readmission (12% vs. 22%, Adjusted odds ratio [aOR], 0.562; 95% confidence interval [CI], 0.344-0.920). Readmissions alone were reduced (11% vs. 22%, aOR, 0.557; 95% CI, 0.338-0.918). No significant associations between the intervention and mortality (aOR, 1.00; 95% CI, 0.21-4.85) or ED visits (aOR, 0.86; 95% CI, 0.52-1.40) were found. Conclusion: The multidisciplinary case review meetings among neurology and rehabilitation staff may greatly reduce 30-day hospital readmissions and mortality after acute stroke hospital discharge.
