Cambodia Integrated HIV and Drug Prevention Implementation Program (CIPI)

HIV risk among female entertainment and sex workers (FESW) remains high and use of amphetamine-type stimulants (ATS) significantly increases this risk. We designed a cluster randomized stepped wedge trial: The Cambodia Integrated HIV and Drug Prevention Implementation [CIPI) study. The CIPI study is embedded within the SMARTgirl HIV prevention program. The CIPI study aimed to recruit FESW from 10 provinces, assessing HIV risk exposures including ATS use. The CIPI study then tested sequentially delivered, behavioral interventions targeting ATS use. The trial combines a 12-week Conditional Cash Transfer (CCT) intervention with four-weeks of cognitive-behavioral group aftercare (AC) among FESW who use ATS. The primary goal of the CIPI study is to reduce ATS use and unprotected sex among FESW. The CCT+AC intervention is being implemented in ten provinces where order of delivery was randomized. Outcome assessments (OEs) including biomarkers and self-reported measures of recent sexual and ATS use behaviors are conducted prior to implementation, and at three 6-month intervals after completion. All women who are ATS negative at 6-months, including those who have completed the CCT+AC intervention are eligible to participate in a micro-enterprise (ME) opportunity. Consultation with multiple groups and stakeholders on implementation factors facilitated acceptance and operationalization of the trial. Statistical power and sample size calculations were based on expected changes in ATS use and unprotected sex at the population level as well as within-subjects. Dissemination of process indicators during the multi-year trial is carried out through annual in-country Stakeholder Meetings. Provincial 'Close-Out' forums are held at the conclusion of data collection in each province. When analysis is completed, dissemination meetings will be held in Cambodia with stakeholders, including community-based discussions sessions, policy briefs, and results published and presented in the HIV prevention scientific journals and conferences. CIPI is the first trial of an intervention to reduce ATS use and HIV risk among FESW in Cambodia. Results will inform both CCT+AC implementation in low and middle-income countries and programs designed to reach FESW.
