INcentives and ReMINDers to Improve Long-term Medication Adherence
Overview
Low medication adherence when initiating antiretroviral treatment (ART) is a key barrier to HIV virologic suppression, resulting in avoidable cases of drug resistance, death, and viral transmission. Routinized pill-taking can lead to successful long-term ART adherence, and short-term behavioral economics-based supports are a novel way to overcome the limited success of existing routinization interventions. This study proposes to test this combined approach for promoting long-term ART adherence using a Stage III Sequential, Multiple Assignment, Randomized Trial (SMART) design in one of the largest HIV clinics in Uganda to identify the most cost-effective adaptive intervention that if found effective is generalizable to other settings and other chronic diseases.
Detailed description
Building on a previous R34 study, the investigators will adapt and deliver the INMIND approach to 550 ART initiators at Mildmay. Participants will initially be randomized to receive either usual care (Control, n=275) or daily text messages (Messages, n=275) to support adherence routines. At months 1 and 2, participants may revise their adherence plans. Those showing \<80% adherence in month 3 will be re-randomized to receive either monthly or monthly escalated prize incentives for the next three months. Adherence will be monitored for an additional 12 months (total follow-up: 18 months) to assess long-term routine maintenance and recovery after interruptions. The SMART design will help identify the most cost-effective intervention sequencing. A cost-effectiveness analysis and stakeholder dissemination will support future scale-up. The investigators hypothesize that Messages will be more effective than Control as a first-stage treatment; that monthly escalated prizes will be more effective than monthly prizes as a second-stage treatment; and that the mechanisms of lack of Salience and Present Bias will mediate the effect of INMIND on our primary and secondary outcomes.
Interventions
- Behavioral Daily Text Messages
Participants will receive daily text message reminders to use their routine behavior to trigger medication adherence. - Behavioral Incentivization based on timely ART adherence
Participants will be eligible to (draw a prize in monthly prize group) or get a monthly prize (monthly escalated group) if they take their medication within +/-one hour of the stated existing routine to which pill-taking is anchored on at least 80% of days for 3-months.
Primary outcome measures
- Electronically measured mean medication adherence [Time frame: 24 months]
Secondary outcome measures (3)
- Retention in Care. [Time frame: 24 months]
- Viral Suppression [Time frame: 24 months]
- Routinization of ART adherence [Time frame: 24 months]
