Medication Adherence in Human Immunodeficiency Virus (HIV)

1 de agosto de 2016 atualizado por: St. Jude Children's Research Hospital

Targeting Enhanced Adherence to Medication: A Pilot Study in Adolescents and Young Adults With Human Immunodeficiency Virus (HIV)

Although effective treatments are currently available to treat human immunodeficiency virus (HIV), the retrovirus leading to acquired immune deficiency syndrome (AIDS), strict adherence to the treatment regimen is required. Nonadherence to highly active antiretroviral therapy (HAART) regimens is well documented in individuals with HIV. This is especially true for adolescents and young adults (AYA), where rates of adherence range from 20 to 100%. Nonadherence has significant implications for subsequent treatment response and health outcomes, including poor virologic response, development of drug resistance, and mortality. Of note, previous research has suggested that every 1% increase in nonadherence is related to a 2% increased likelihood of detectable viral load (VL) in youth with behaviorally acquired HIV. Furthermore, higher VL is the most salient variable related to increased risk of virus transmission. Thus, nonadherence to HAART is a significant public health issue.

The objective of the proposed research plan is to systematically examine an individualized, behavioral intervention targeting HAART nonadherence in AYAs initiating HAART. The current intervention will support AYA participation in brief, staff-delivered instruction in adherence-promotion skills. Individualized behavioral analysis and motivational interviewing will be applied to provide effective solutions for current barriers to HAART adherence before and after HAART initiation, as recommended by the Panel on Antiretroviral Guidelines for Adults and Adolescents.

Visão geral do estudo

Descrição detalhada

The proposed pilot study will utilize a randomized controlled trial to estimate the feasibility, acceptability, and preliminary efficacy of a novel intervention for AYAs diagnosed with behaviorally-acquired HIV initiating HAART.

Standard care for HIV at St. Jude Children's Research Hospital (SJCRH) includes a placebo pill trial to assess patient readiness for therapy prior to starting HAART. Participants on this study will be randomized to either: a control arm of standard therapy, or standard therapy plus an individualized behavioral, staff-delivered intervention (Pill Trial+).

Participants in the control arm will receive standard clinical care. Participants in the Pill Trial+ arm will receive standard therapy plus three 25-minute individualized, behavioral, staff-delivered intervention sessions at HAART initiation, and 1-, and 3-month follow-up visits. Two brief booster sessions will also be provided to the Pill Trial+ arm following sessions 1 (in clinic) and 2 (by phone). In-person intervention sessions and all questionnaires will be completed in conjunction with scheduled clinical care visits. Sessions and measures will be completed by phone at designated time points if a participant becomes unavailable to return to clinic due to extenuating circumstances.

As recommended by Panel guidelines, discussion of placebo pill trial adherence during the first 25-minute session will provide a novel mechanism to discuss barriers to adherence and provide intervention prior to HAART initiation. Remaining sessions will promote adherence following HAART initiation using behavioral problem-solving and motivational interviewing strategies.

Primary Objective:

  • To estimate a) rate of consent to the randomized trial and b) differences between the intervention and control conditions with respect to HAART adherence, as measured by pill count.

Secondary Objectives:

  • To estimate differences between the intervention and control conditions with respect to other measures of adherence, including HAART self-reported adherence, HAART pharmacy refill, and clinic attendance.
  • To examine disease and patient-reported outcomes during the first 6 months following HAART initiation and their relationship to participation in the Pill Trial+ intervention.

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Outro: Standard Care
Participants in the Standard Care group will complete a demographic questionnaire at the time of consent as well as other questionnaires during the course of the study. They will receive standard clinical care.
Participants will complete a questionnaire developed for the purposes of the current study assessing basic background information.
Self-reported adherence, health-related quality of life and other questionnaire measures will be administered using a password protected laptop the same day as participants' regularly scheduled outpatient clinic appointments.
Experimental: Pill Trial+
Participants in the Pill Trial+ group will complete a demographic questionnaire at the time of consent as well as other questionnaires during the course of the study. They will receive standard clinical care plus three 25-minute individualized, behavioral, staff-delivered intervention sessions at HAART initiation, and 1-, and 3-month follow-up visits.

In addition to standard clinical care, participants in the Pill Trial+ arm will receive staff-delivered intervention sessions individualized for each participant at HAART initiation, 1-month, and 3-month follow-up. Two booster sessions will also be provided at two weeks following intervention session 1 (in clinic) and intervention session 2 (by phone) to assess any difficulties using the created adherence plans.

Mixed effects models will be employed to explore the efficacy of the intervention on virologic response, HRQOL, and medical beliefs. VL, CD4 count/%, HRQOL, and beliefs will be used as the response variables, respectively, while time since treatment, intervention, and their interaction will be included as covariates.
