Hypothesis
Does a two-way texting intervention improve retention on antiretroviral therapy among people living with HIV in Malawi?
Conclusion
Higher implementation fidelity of the texting intervention was linked to better clinic attendance and care outcomes.
Supporting Evidence
- Participants received motivation messages for 75% of enrolled weeks.
- Appointment reminders were sent for 90% of eligible appointments.
- Receiving a reminder message increased the odds of attending appointments by 83%.
Takeaway
This study shows that sending text messages to remind people about their doctor appointments can help them remember to go, which is important for their health.
Methodology
The study used SMS data and ART refill visit records to evaluate adherence to the texting intervention and its impact on appointment attendance.
Potential Biases
Potential biases include user connectivity issues and participant engagement over time.
Limitations
The study primarily assessed message delivery success and did not verify if messages reached the intended participants.
Participant Demographics
Participants were adults aged 18 and older who initiated ART at the clinic.
