Study information

Scientific title

A randomized control trial of peer-delivered modified directly observed therapy for HAART in Mozambique.


Study hypothesis

Our hypothesis is that modified Directly Observed Therapy (mDOT) during the initial six weeks of HAART, supervised primarily by Human Immunodeficiency Virus (HIV) positive lay activists, will improve adherence and clinical outcomes compared with those that do not have supervised mDOT.

We also hypothesize that the benefits of mDOT will be achieved through a variety of mediators that will result from the social interactions the patients will have with the activists. These mediators include: improved social support, improved knowledge about HAART, reduced stigma, and improved self-efficacy.

Adherence to highly active antiretroviral therapy (HAART)


The project is a randomized controlled trial among a sample of HIV positive antiretroviral-naive patients newly starting HAART, randomized to either receive six weeks of modified DOT in addition to standard clinical and adherence support, or standard care only.

The package of standard care includes:
clinical and laboratory assessments related to starting and monitoring HAART, including follow-up consults every month for three months, followed by every three months thereafter, and Cluster of Differentiation-4 (CD4) testing at pre-initiation of HAART and every six months.

Pre-HAART adherence assessment, with a social worker, during which AntiRetroViral (ARV) treatment is explained, expectations clarified, and barriers to adherence identified and addressed. A method of patient localization is also required, which may include leaving a phone number or, in cases where phones are not available, a home visit. Treatment partners are recommended but not required.

Post-HAART adherence support is provided through counseling by all members of the healthcare team, including the physician or physicians’ assistant during regularly scheduled clinic appointments, and a pharmacist or pharmacy technician and social worker at the time of each medication refills. Additional visits are performed as needed by a social worker and activists, who may become involved in cases of poor adherence. Referrals to community-based organizations for adherence support may also be performed.

In addition to this standard package of care, the patients are randomized to the intervention group will receive six weeks of modified DOT. Modified DOT includes supervising, via direct observation, the morning weekday doses of patients’ medications in the clinic, while night time and weekend doses are self-administered.
The six-week timeframe for mDOT was chosen to cover the initial time of treatment when the importance of adherence may be heightened, when side effects leading to poor adherence may be most pronounced, and when chronic pill-taking behaviors may be reinforced. The direct observation will be performed primarily by DOT activists, who are full-time paid HIV-positive lay employees of the clinic whose primary job is to ensure the adherence of patients on HAART. During DOT sessions, their interactions with patients are to include, in addition to supervising and recording the swallowing of pills, counseling and educating patients regarding general HIV-related information, their treatment, and care plan. Patients not reporting to clinic to take their medication during DOT are located on the same day by the activists usually through home visits or phone calls (if possible). Such patients are also brought their dose of medication to take, and the activists reinforce the importance of good adherence.
