Abstract 119: Final Patient-Level Results From the Michigan Stroke Transitions Trial (MISTT): A Randomized Clinical Trial to Improve Stroke Transitions

Abstract

Background: Navigating the transition after returning home following a stroke can be associated with substantial psychosocial and health-related challenges. The Michigan Stroke Transitions Trial (MISTT) tested the efficacy of a social work case management (SWCM) program and access to an online information and support resource (MISTT Website) to improve outcomes in acute stroke patients who returned home. Methods: MISTT was a randomized, pragmatic, open, 3-group parallel designed trial conducted in 3 Michigan hospitals. Eligible subjects were acute stroke patients who returned home either directly or within 4 weeks of being discharged to a rehab facility. A total of 265 patients were randomized to one of 3 groups: 1) usual care, 2) SWCM program only, or 3) SWCM plus MISTT Website access. Interventions concluded after 90-days. Primary outcomes including Quality-of-Life (PROMIS Global-10 physical- and mental-health subscales) and the Patient Activation Measure (PAM) were collected by telephone at 7- and 90-days. The change in outcomes (90-day minus 7-day) between the three treatment groups was assessed using a differences-in-differences (D-in-D) analysis. Results: The mean age of the 265 randomized subjects was 66 years, 49% were female, 21% non-white, 14% had hemorrhagic stroke, 56% were discharged to a rehab facility. Following the intervention there were statistically significant treatment group differences in PROMIS physical-health (p=0.003) and PAM (p=0.042), but not PROMIS mental-health (p=0.56). Mean change in physical-health scores for group-3 (SWCM+Website) was significantly higher than both group-1 (Usual Care) (difference= 3.4; 95%CI=1.41, 5.33; p<0.001) and group-2 (SWCM) (difference= 2.4; 95%CI=0.46, 4.34; p=0.02). The mean change in PAM scores for group-3 was significantly higher than group-2 (6.7; 95%CI=1.26, 12.08; p=0.02) and marginally higher than group-1 (5.0; 95%CI=-0.47, 10.52; p=0.07). Conclusion: An intervention that combined social worker-led case management with access to online stroke-related information produced greater gains in patient-reported physical health and activation compared to usual care or case management alone.
