Incentives for Uptake of and Adherence to Outpatient Stroke Rehabilitation Services: A 3-Arm Randomized Controlled Trial.

OBJECTIVE: To determine if rehabilitation uptake and adherence can be increased by providing coordinated transportation (increased convenience) and eliminating out-of-pocket costs (reduced expense). DESIGN: Three-arm randomized controlled trial. SETTING: Stroke units of 2 Singapore tertiary hospitals. PARTICIPANTS: Singaporeans or permanent residents 21 years or older who were diagnosed as having stroke and were discharged home with physician's recommendation to continue outpatient rehabilitation (N=266). INTERVENTIONS: A Transportation Incentives arm (T), which provides free transportation services, a Transportation & Sessions Incentives arm (T&S), offering free transportation and prescribed stroke rehabilitation sessions, and a control arm, Education (E), consisting of a stroke rehabilitation educational program. MAIN OUTCOME MEASURES: The primary study outcome was uptake of outpatient rehabilitation services (ORS) among patients poststroke and key predefined secondary outcomes being number of sessions attended and adherence to prescribed sessions. RESULTS: Uptake rate of ORS was 73.0% for E (confidence interval [CI], 63.8%-82.3%), 81.8% for T (CI, 73.8%-89.8%), and 84.3% for T&S (CI, 76.7%-91.8%). Differences of T and T&S vs E were not statistically significant (P=.22 and P=.10, respectively). However, average number of rehabilitation sessions attended were significantly higher in both intervention arms: 5.50±7.65 for T and 7.51±9.52 for T&S vs 3.26±4.22 for control arm (E) (T vs E: P=.017; T&S vs E: P<.001). Kaplan-Meier analysis indicated that persistence was higher for T&S compared with E (P=.029). CONCLUSIONS: This study has demonstrated a possibility in increasing the uptake of and persistence to stroke ORS with free transportation and sessions. Incentivizing survivors of stroke to take up ORS is a new strategy worthy of further exploration for future policy change in financing ORS or other long-term care services.
