This report presents the results of the first-ever national assessment of water, sanitation, and hygiene (WASH) and health-care waste management services, including climate resilience, in health care facilities (HCFs) in the Lao People’s Democratic Republic. Conducted from 2020–2021, the survey covered 1,225 HCFs nationwide. It offers critical insights into the current state of WASH services and gaps at both national and provincial levels, and outlines evidence-based actions and a monitoring framework to guide improvements in WASH and health system resilience through 2025 and beyond.
