Abstract: Introduction: In Kenya, Community Based Health Information System (CBHIS) plays a pivotal role in ensuring HIV/AIDS data from grass-root and community level is collected and report for evidence-based decision-making. This information is pivotal for evidence-based planning and programming However, quality of data in CBHIS has been persistently reported to be poor. This can adversely hamper achievement of the goal of zero infections rates in the coming years. Therefore, the aim of this study was to determine factors associated with perceived quality of HIV/IDS data reported into the CBHIS in Kenya.
