Clinical Trial Summary
The investigators broadly aim at determining barriers and facilitators to PrEP uptake and
adherence and retention among the study participants. The investigators have the following
specific objectives of determining: (1) the PrEP knowledge levels, attitudes, practices, and
user experiences among injecting and sexual partners of PWID in Nairobi County (2) the
socio-demographic, behavioural, and structural factors hindering the uptake of PrEP among
PWID's sexual and injecting partners in Nairobi County; and (3) the effect of a theory-guided
behavioural intervention (PrEP-UP) utilizing peer outreach and navigation on the uptake of
PrEP by the study participants.
The investigators hypothesize that: PWID's injecting and sexual partners in Nairobi City lack
PrEP knowledge, and have poor attitudes practices, and user experiences about PrEP; less than
50.0% of the PWID's sexual and injecting partners in Nairobi County have socio-demographic,
behavioural and structural factors hindering their uptake of PrEP; and a theory-guided
behavioural intervention (PrEP-UP) utilizing peer outreach and navigation has no effect on
the uptake of PrEP by the study participants.
Description:
Background: The annual global number of new HIV infections among adults has remained
unchanged over the last decade and it is largely fuelled by key populations among them people
who inject drugs (PWID). Key populations in Kenya account for one-third of all new HIV
infections and 18.3% of PWID in the country are living with HIV. Drug and substance use is on
the increase in the country, with close to 4 out of 10 Kenyans reporting to have used a
substance in their lifetime including injectable drugs thus fueling the spread of HIV.
Pre-Exposure Prophylaxis (PrEP) is effective in the prevention of HIV transmission among PWID
by over 70.0% if and when used correctly. However, uptake, adherence, scale-up of use,
coverage and retention currently remain limited. Thus, effective interventions are needed to
enhance the uptake of PrEP among PWID and their sexual and injecting partners in order to
prevent HIV transmission.
Objectives of the Study: Broadly, the investigators aim at determining PrEP uptake barriers
and facilitators and adherence among the study participants and the sequel of a theory-guided
behavioral intervention model (PrEP-UP) on the uptake of PrEP by the study participants.
Specifically, the investigators aim at determining: (1) the PrEP knowledge levels, attitudes,
practices and user experiences among the study participants(2) the socio-demographic,
behavioural and structural factors hindering the uptake of PrEP among the study participants;
and (3) the effect of a theory-guided behavioural intervention (PrEP-UP) utilizing peer
outreach and navigation on the uptake of PrEP by the study participants.
Methods: The investigators will conduct the study for twelve months (1st July 2021 to 30th
June 2022) and they will use an implementation study through a pre-post design to assess 256
participants' self-reported PrEP uptake and retention before and after exposure to a
theory-guided behavioural intervention (PrEP-UP) utilizing navigators and peer outreach for
the 128 'cases' and PrEP information Pamphlet and list of health facilities offering PrEP for
free in Nairobi County for the 128 'control' group members. The investigators will use four
study sites namely Githurai, Kawangware, Ngara and Pangani PWID's hotspots within Nairobi
City. The targeted study participants are PWID's sexual and injecting partners of ages 18
years and above. The investigators will recruit 256 study participants into the study by use
of peers and social workers in the University of Washington's Needle and Syringe Program
(NSP) sites in Githurai, Kawangware, Ngara and Pangani. The investigators will collect
baseline data after recruitment while the interventions for both groups will be offered in a
maximum 5 contact sessions with investigators and a follow-up of the participants will be
done by the investigators at weeks 4, 8 and 12 to establish whether study participants have
taken up PrEP by week 12 during which post-intervention data will be collected. Lastly,
participants' self-reported PrEP retention will be documented by investigators at 18 weeks
and HIV tests will be conducted on the participants by the investigators (optional) through
OraQuick antibody HIV tests. The investigators will analyze: quantitative data through the
Statistical Package for Social Sciences (SPSS) version 24 and: qualitative data through flow
chart matrices to establish divergence and convergence of themes.
Significance of the Study: Through the study, the investigators will contribute to the global
call for the reduction in new HIV infections among PWIDs and their sexual and injecting
partners. The study will further inform the investigators on the effectiveness-implementation
science interventions and recommend the best PrEP scale-up approaches in addition to
contributing to the global scientific knowledge.
