About this study

When antiretroviral therapy (ART) is taken correctly, it can dramatically improve the health and well-being of HIV-infected individuals. However, when the treatment regimen is not followed carefully, the therapy can be ineffective in managing one's HIV, and also can allow for the development of strains of HIV that may be resistant to treatment. Effective ART adherence interventions can help patients to avoid potentially serious individual and public health consequences of suboptimal adherence, but such interventions are often expensive and too intensive for clinics to support offering over time to their patients. This study will develop and evaluate the effectiveness of an individualized, interactive, computer-software intervention program delivered in clinical care in increasing ART adherence in HIV-infected individuals. Because the intervention is a software program, clinic resources required for implementation and sustaining availability over time are minimized.

Participants in this ~18-month study were recruited from one of 5 participating clinics that provide HIV care and randomly assigned to control (an assessment only version of the software) or intervention (assessment and tailored intervention software) arm. Participants completed their assigned task in concert with their regularly scheduled HIV medical care visits (but no more frequently than once a month). Primary outcomes were measured at each medical visit. The effect of the adherence intervention was evaluated through comparison of treatment and control arm adherence reports over time and VL.

Treatment and study plan

LifeWindows Intervention Sessions

Behavioral

At each clinical care visit, intervention arm participants use the full LifeWindows program, which includes welcome and assessment surveys and also includes the active intervention modules. ART adherence promotion intervention activities are tailored to the participant's assessment responses. Participants select which activities he or she wishes to use which culminates in an adherence specific goal.

Control

Other

At each clinical care visit, control arm participants use the portion of the LifeWindows software program that provides a welcome from the avatar and collection of assessment items/surveys.

Primary outcomes

  1. AIDS Clinical Trials Group (ACTG) 3-day Recall Measure of Doses Taken

    Time frame: Measured at each clinical care visit over 18 months of participation

    This measure asks participants to report the number of doses taken on each of the past 3-days, relative to number he or she was prescribed to take, and produces a % adherence score. For this study, adherence over the past 3-days was established for each medication separately then averaged over the full regimen. For main outcomes, perfect vs imperfect adherence was evaluated. Significant findings on perfect/imperfect adherence were followed with sensitivity tests to determine if lowest threshold (eg., 90%, 80%, 70% adherence) effect was maintained.

  2. Visual Analog Scale Measure of Adherence to ART

    Time frame: Measured at each clinical visit over 18 months of participation

    This measure asks participants to rate their adherence over the past 3 to 4 weeks using a line that marks from 0 to 100% of doses taken. For this study, this item was asked for each antiretroviral in one's regimen and a total score was produced by averaging all reports. For main outcomes, perfect vs imperfect adherence was evaluated.

Secondary outcomes

  1. Viral Load Count

    Time frame: Measured over 18 months

    Viral load data extracted from medical records beginning 30 days prior to baseline.
