BACKGROUND: The estimated number of people living with HIV in Cambodia in 2021 was 74,000, with 10,000 undiagnosed. To move from the current 84% who are aware of their infected status to 95% requires data-driven interventions and collaborative efforts. HIV transmission in Cambodia is highest among key populations (KPs) who account for 77% of new infections (Asian-Epidemic-Modeling 2021[MJ1] ). With support from the Global Fund and the National Center for HIV/AIDS, Dermatology, and STD (NCHADS), four community-based organizations (CBOs) implemented HIV prevention and testing services in 20 provinces. Initially, CBOs used different data collection tools and database systems and reported only aggregate data to NCHADS, making it impossible to perform more granular data analysis and data-driven discussion.
DESCRIPTION: In 2018, NCHADS, with technical assistance from the USAID/PEPFAR-funded EpiC project and other stakeholders, initiated, and established the national prevention database (NPD) with standard indicators, data collection tools, and reporting templates. The NPD uses DHIS2 to track individual-level KP data from CBOs and allows HIV positive KPs to be linked to the national antiretroviral therapy (ART) surveillance database. The NPD allows NCHADS to customize dashboards and reports to reflect national standard indicators, sub-national and donor reports with detailed granular analysis of the HIV prevention and testing cascade by reach, and testing modality. It includes hot-spot GIS-mapping-data linked with prevention data. In 2022, the NPD reported reaching 94,142 unique KPs: 82,825 tested for HIV; 2,198 screened HIV reactive; 2,182 confirmed HIV positive; and 2,174 enrolled in ART.
LESSONS LEARNED: The detailed KP prevention and testing data include different modalities of reach and recency testing linked to hot-spot GIS mapping in the NPD. This allows NCHADS to have routine data-driven discussions to identify key challenges and improve HIV prevention and testing. The NPD informs AEM projection for HIV and KP size estimations.
CONCLUSIONS: The NPD is a unique and comprehensive database that collects, stores, analyzes, and visualizes detailed information of KPs and HIV-related services across the country in real time. Granular data generated from the NPD is essential for Cambodia to improve HIV prevention efforts and strengthen new case finding to reach the 95% target.
