Test of a web-based program to improve adherence to HIV medications

Area of Science:

• Public Health
• Infectious Diseases
• Behavioral Science

Background:

• HIV infection requires lifelong antiretroviral therapy (ART).
• Medication adherence is crucial for effective HIV management and preventing drug resistance.
• Web-based interventions offer scalable solutions for chronic disease management.

Purpose of the Study:

• To evaluate the effectiveness of a web-based Life-Steps intervention for improving ART adherence in HIV+ individuals.
• To assess the impact of the intervention on viral load reduction.
• To determine the feasibility of implementing such a program.

Main Methods:

• 168 HIV+ adults were randomized to a web-based Life-Steps program or a waitlist control.
• Antiretroviral medication adherence was measured using electronic pill caps (MEMS caps).
• Data were collected at baseline and at 3, 6, and 9 months, including viral load measurements.

Main Results:

• Participants in the web-based Life-Steps group showed significantly higher ART adherence rates over 9 months compared to the control group.
• The intervention group experienced a significant decrease in viral load.
• The web-based program proved to be a useful and implementable tool.

Conclusions:

• A web-based Life-Steps intervention is effective in enhancing medication adherence for HIV+ patients.
• The program contributes to improved virologic outcomes, indicated by reduced viral load.
• Digital health tools can support long-term HIV management and adherence.
