Clinical Trial Summary
The purpose of this study is to see if a computerized counseling tool helps patients reduce
their sexual transmission risk and improve their antiretroviral adherence.
Description:
Helping people living with HIV to remain healthy and reduce transmission to sexual partners
('positive prevention') can be accomplished by behavioral counseling and supporting adherence
to infectivity-reducing antiretroviral therapy (ART). Positive prevention and ART adherence
approaches that are not staff-dependent are urgently needed in Africa, the region hardest hit
by HIV and decimated health workforce. Interactive health communication tools offer one
approach. We will adapt a computerized counseling intervention found to be efficacious in
reducing HIV-1 viral load and risk behaviors in the US ('CARE+') with the largest HIV
provider in Kenya, the Academic Model for the Prevention and Treatment of HIV/AIDS (AMPATH).
Aim 1: Adapt a theoretically driven computerized counseling intervention for use in Kenya
('CARE+_Kenya'). Conduct in-depth interviews with n≤ 50 urban and rural AMPATH patients to
understand HIV support needs, and two staff focus groups to assess counseling practices and
beliefs about computer use. Modify intervention content; translate and record audio into
local Kiswahili. Adapt skill-building videos (e.g., on secondary prevention, HIV disclosure,
ART adherence, reproductive health). Conduct software usability testing with n=20 patients
and n=8 staff. Perform 3-day test-retest reliability assessment to establish psychometric
performance of measures.
Aim 2: Establish biological and behavioral efficacy of CARE+_Kenya. Longitudinal randomized
controlled trial (RCT) in one urban and one rural AMAPATH clinic. Randomly assign
HIV-positive adults with any missed ART or unprotected sex in last 6 months, >1 sex partner
in last year, or sexually transmitted infection (STI)diagnosis in last 3 years, to
intervention (n=125) or risk-assessment control (n=125) for baseline, 3, 6, and 9 month
sessions. HIV transmission risk will be measured by self-reported unprotected sex with HIV
negative/unknown partner, and trends in Chlamydia trachomatis, Neisseria gonorrhoeae, and T.
vaginalis. ART adherence will be measured by HIV-1 viral load, electronic monitoring,
pharmacy refill, self-report, and clinic attendance. Aim 3: Establish cost-effectiveness of
CARE+_Kenya. At baseline, follow 100 patients at each of the two clinics to evaluate standard
of care counseling, and collect time-spent and facility data to determine costs and unmet
counseling need. Conduct economic evaluation to compare CARE+_Kenya vs. standard of care. If
the RCT shows that the intervention reduces viral load and transmission risk behaviors, we
will use a Bernoulli transmission dynamics model to estimate number of secondary HIV
infections prevented; then create a cost-effectiveness model to calculate 2 incremental
cost-effectiveness ratios: 1) cost per HIV infection averted, and 2) cost per daily adjusted
life year saved. If CARE+_Kenya is efficacious and efficient, we will develop a proposal for
a cluster-randomized trial to assess translational effectiveness of CARE+_Kenya throughout
the AMPATH system. This is directly responsive to PA-08-107's call for innovative, integrated
interventions that leverage ART roll-out infrastructure in international settings to benefit
people living with HIV.
