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

Published:September 10, 2021DOI:https://doi.org/10.1016/j.apmr.2021.08.013

      Abstract

      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.
