The Mobile and Scalable Innovations for Measles Immunization (M-SIMI) Trial: A Protocol for a randomized controlled trial that assesses the impact of text message reminders and unconditional monetary incentives to improve measles vaccination in western Kenya
ABSTRACT
Background:
Globally, 21 million children do not receive measles vaccine each year. With high levels of mobile phone access and ownership, opportunities exist to leverage mobile-health technologies to generate demand for immunization.
Objective:
The Mobile and Scalable Innovations for Measles Immunization (M-SIMI) trial aims to determine if text message (short message service, SMS) reminders, either with or without mobile phone-based incentives, can improve measles immunization coverage and timeliness in rural western Kenya.
Methods:
This is a three-arm, parallel, randomized controlled trial. Caregivers in Siaya County, Kenya will be randomized and evenly allocated to one of three study arms: (1) control; (2) SMS reminders only; and (3) SMS reminders +150 Kenya Shilling (KES) incentive. Participants assigned to the SMS group will be sent SMS reminders three days and on the day before measles immunization visit scheduled at nine months of age. Participants in the incentive arm will, in addition to SMS reminders as above, be sent an unconditional 150 KES mobile-money incentive to their mobile phone three days before the child’s nine month birthday. Children will be followed to age 12 months to assess the primary outcome, measles vaccination by 10 months of age. Log-binomial regressions will be used to calculate relative risks.
Results:
Enrollment was completed in March 2017 and results will be made available in early 2019.
Conclusions:
Few randomized controlled trials have examined the effect of text message reminders to improve measles immunization coverage. This is the first study to assess the effect of both SMS reminders unconditionally provided mobile-money incentives to improve measles immunization coverage Clinical Trial: The trial was registered at clinicaltrials.gov (NCT02904642) in September 2016.
