Interventions to Improve HIV Antiretroviral Therapy Adherence

September 22, 2021 updated by: James Riddell, University of Michigan

Interventions to Improve HIV Antiretroviral Therapy Adherence in Sofala Province Mozambique

This study will explore whether financial incentives, reminders, information about HIV/AIDS and its treatment and anti-stigma counseling help improve anti-retroviral therapy (ART) adherence among HIV infected individuals in a resource-limited environment. The interventions will be randomized in the study population in a cross-cutting design, with a control group, a financial incentive treatment group, a reminders treatment group, a treatment group that receives both the financial incentive and reminder interventions. In addition, there will be an information treatment group, a stigma-relieving treatment group and a group that receives both information and stigma-relieving interventions. The primary outcomes of interest for this study will be the adherence to ART, measured by attendance rates at clinic appointments and refill collection rates.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Control Group
Experimental: Financial Incentive Group
Behavioral: Financial Incentive
Financial Incentive: Participants will receive monthly financial incentives each time they refill the ART medication on time for six months
Experimental: Reminders Group
Behavioral: Reminders
Reminders: Participants will receive monthly reminder phone calls before their ART medication refill is due for six months.
Experimental: Financial Incentive and Reminders Group
Behavioral: Financial Incentive and Reminders
Interaction: Participants receive both the Financial Incentives and Reminder Calls.
Experimental: Information Group
Behavioral: Information
Information: show the participants a video about HIV progression, mechanism of ART, the benefit of adhering to ART.
Experimental: Stigma-relieving Group
Behavioral: Stigma-relieving
Stigma-Reliving: Upon recruitment, inform the participants of the results of a recent population survey regarding people's attitudes towards HIV, if they overestimate the social stigma related to HIV. This intervention intends to reduce the stigma-concern faced by the patients.
Experimental: Information and Stigma-relieving Group
Behavioral: Information and Stigma-relieving
Information and Stigma-relieving: Upon recruitment, show the participants a video about HIV progression, mechanism of ART, the benefit of adhering to ART. In addition, inform the participants of the results of a recent population survey regarding people's attitudes towards HIV, if they overestimate the social stigma related to HIV.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Medication possession ratio (MPR) at least 95%, 6 month window
Time Frame: 0-6 month interval from date of study enrollment
Fraction of participants for whom MPR is greater than or equal to 95%. MPR is proportion of days that a respondent is in possession of at least one ART dose. MPR is computed from pharmacy dispensing records. Measurement window truncated to last visit date for patients who transfer clinics, opt out of future study participation, or die.
0-6 month interval from date of study enrollment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Medication possession ratio (MPR) at least 95%, 3 month window
Time Frame: 0-3 month interval from date of study enrollment
Fraction of participants for whom MPR is greater than or equal to 95%. MPR is proportion of days that a respondent is in possession of at least one ART dose. MPR is computed from pharmacy dispensing records. Measurement window truncated to last visit date for patients who transfer clinics, opt out of future study participation, or die.
0-3 month interval from date of study enrollment
Medication possession ratio (MPR) at least 80%, 6 month window
Time Frame: 0-6 month interval from date of study enrollment
Fraction of participants for whom MPR is greater than or equal to 80%. MPR is proportion of days that a respondent is in possession of at least one ART dose. MPR is computed from pharmacy dispensing records. Measurement window truncated to last visit date for patients who transfer clinics, opt out of future study participation, or die.
0-6 month interval from date of study enrollment
Medication possession ratio (MPR) at least 80%, 3 month window
Time Frame: 0-3 month interval from date of study enrollment
Fraction of participants for whom MPR is greater than or equal to 80%. MPR is proportion of days that a respondent is in possession of at least one ART dose. MPR is computed from pharmacy dispensing records. Measurement window truncated to last visit date for patients who transfer clinics, opt out of future study participation, or die.
0-3 month interval from date of study enrollment
Appointment attendance rate (AAR)
Time Frame: 0-6 month interval from date of study enrollment
Average AAR among participants. AAR is proportion of scheduled visits completed during the observation period. "Completed visit" considered done if patient visits clinic on scheduled appointment date, or up to 7 days prior to that date. AAR is computed from clinic records. Measurement window truncated to last visit date for patients who transfer clinics, opt out of future study participation, or die.
0-6 month interval from date of study enrollment
Lost to follow-up (LTFU)
Time Frame: 0-6 month interval from date of study enrollment
Fraction of participants lost to follow up (LTFU). LTFU indicates patient missed last appointment and 90 or more days have elapsed since patient's last scheduled appointment date, with no clinic record of contact since that date. Patients who transfer clinics or opt out of future study participation are excluded from LTFU denominator, but those who die are retained in LTFU denominator.
0-6 month interval from date of study enrollment
Test Referral, 1-month window
Time Frame: 1 month interval from date of study enrollment
This is a binary variable, which takes value 1 if the participant has a successful referral to test for HIV within 1 month of recruitment and 0 otherwise. A participant is considered having a successful referral if someone approaches our study team in the clinic, present us with the proof of an HIV testing together with the barcode-card we distributed to the participant upon recruitment.
