Summary
Directly administered antiretroviral therapy (DAART) significantly improves medication adherence for people with HIV. This community-based approach, particularly when supervised, is crucial for managing HIV in vulnerable populations.
Area of Science:
- Public Health
- Infectious Diseases
- Clinical Medicine
Background:
- Human immunodeficiency virus (HIV)-infected drug users often face challenges with medication adherence.
- High rates of comorbidities like homelessness, depression, and substance abuse complicate HIV treatment.
- Baseline characteristics revealed significant health burdens, including low CD4+ counts and high viral loads.
Purpose of the Study:
- To evaluate the essential features of a community-based Directly Administered Antiretroviral Therapy (DAART) intervention.
- To compare adherence rates between DAART and self-administered therapy in a randomized controlled trial.
- To identify acceptable venues and essential components for a successful DAART program.
Main Methods:
- A randomized controlled trial comparing DAART with self-administered therapy.
- Inclusion of a diverse population with significant social and medical comorbidities.
- Assessment of subject preferences for DAART venues and acceptance of compulsory treatment.
Main Results:
- Supervised medication administration showed significantly higher adherence than unsupervised (P<.0001).
- A mobile syringe-exchange program was the most acceptable venue (83%), while methadone clinics were least acceptable (36%).
- Despite preference for self-administration, a majority (76%) would accept compulsory DAART.
Conclusions:
- Community-based DAART is an effective strategy for improving HIV treatment adherence.
- Intervention design should prioritize convenience, flexibility, confidentiality, and specialized staff training.
- Tailoring DAART delivery to patient preferences and context, such as utilizing mobile services, is key to successful implementation.
