BACKGROUND: Patients with initial stroke or transient ischemic attack (TIA) are at high risk for further strokes, death or cardiovascular events. Even the first-ever stroke is associated with a high chance of disability and need for assistance. The risk of long-term health care demands increases with each subsequent event. Although the inpatient sector already provides a high standard of care in Germany, it can be difficult to obtain cross-sectoral aftercare. Thus, the study investigated whether a structured case management program can avoid stroke recurrences.; METHODS: The study was conducted with a quasi-experimental study design in three regions in North Rhine-Westphalia. Patients with first-ever stroke or TIA were eligible to participate. The intervention group was prospectively recruited and supported by a case manager during a one-year follow-up. Optimal Full Matching was used to generate a control group based on statutory claims data. The primary outcome was the stroke recurrence. Recurrence and mortality were analysed by using Cox regression; other secondary outcomes were examined with test-based procedures and with logistic regressions. Additionally, subgroup analyses were performed.; RESULTS: From June 2018 to March 2020, 1,512 patients were enrolled in the intervention group. Claims data from 19,104 patients have been transmitted for establishing the control group. After the matching process, 1,167 patients of each group were included in the analysis. 70 recurrences (6.0%) occurred in the intervention group and 67 recurrences (5.7%) in the control group. With a hazard ratio of 1.06 (95% CI: [1.42-0.69]; p=0.69), no significant effect was found for the primary outcome. With regard to the secondary outcome mortality, 36 patients in the intervention group and 46 in the control group died (3.1% vs. 3.9%). Again, there was no significant effect (HR: 0.86; 95% CI: [0.58-1.28], p=0.46).; DISCUSSION: Based on the present findings, the case management approach for stroke patients evaluated here was unable to demonstrate an improvement in health care. Potential effects of case management might not be adequately depicted in short observation periods. Thus, future studies should consider longer observation periods.; CONCLUSION: A panel of experts should discuss whether the core approach of case management to support cost-intensive individual cases is contrary to a broad implementation with a one-size-fits-all intervention for stroke patients. In this case, further research should focus on more specific study populations. Copyright © 2023. Published by Elsevier GmbH.
