Official title: INcentives and ReMINDers to Improve Long-term Medication Adherence

Status Active, not recruiting

Clinical Trial Summary

The study will test the feasibility and acceptability of using text messages and behavioral economics-based incentives to support anchoring Anti-Retroviral Therapy (ART) adherence to an existing routine in order to improve long-term ART medication adherence. The intervention phase of the three-phased study will constitute the pilot RCT. A sample of 150 clients who have initiated ART in the preceding three months will be randomized to either usual care (C = 50) or one of the two INMIND intervention groups (daily text message reminders with or without incentives) for three months (T1 = 50; T2=50). Subsequently, behavioral persistence will be evaluated for six months post-intervention. Assessments will be conducted at baseline, month 3, and month 9. The primary outcomes are 1) electronically measured mean medication adherence during the intervention and 2) six months post intervention, along with 3) timeliness of medication adherence during the intervention and 4) six months post-intervention.

Clinical Trial Description

Adherence of Anti-Retroviral Therapy (ART) among HIV-infected patients initiating treatment (treatment initiators) in Sub-Saharan Africa has remained low, even though the number of treatment initiators has increased in recent years. Lack of retention in care and low adherence in the first year of ART treatment are substantial barriers to virologic suppression. The current R34 study tests a novel approach for improving long-term ART adherence among treatment initiators by turning adherence into a behavioral routine. This is done in two ways: 1) anchoring ART adherence to an existing routine, and 2) providing more immediate rewards and increasing the salience through reminder messages. Insights from behavioral economics suggest that such an intervention may be particularly effective for people with present bias (those who have a tendency to give in to short-term temptation at the cost of more long-term benefits) and lack of salience (where over time, the choice of target behavior is overshadowed by more pressing needs of daily life) which have been found to be prevalent among people living with chronic medical conditions from past studies. The intervention will be tested through a pilot RCT, wherein 150 adult clients will be randomly assigned to three groups. The first intervention group would receive daily text messages that reinforce routine formation information provided to all participants (across the three groups). The second intervention group will receive the text messages, and additionally be eligible for a prize drawing based on timely ART adherence, at each monthly clinic visit. The control group will receive care as usual, consisting of routine formation information as well as adherence counseling. The intervention will last three months, with a six-month post-intervention follow up period. All participants will receive MEMS caps to record adherence, and will complete assessments over nine months (baseline, post-intervention, and six months post-intervention). The Specific Aim of the intervention phase of the study is to test the preliminary effectiveness of the intervention, including the relative effectiveness of the two different implementation approaches. This is preceded by the formative phase, with the Specific Aim of developing the intervention parameters. The intervention phase is succeeded by the adaptation phase, whose Specific Aim is to collect data in preparation for a subsequent R01 application. ;
