Adequate water, sanitation and hygiene (WASH) in healthcare facilities (HCFs) is critical to the delivery of high-quality and safe care, yet the first global WASH in HCF status report in 2015 revealed a crisis in this fundamental aspect of quality healthcare. This report synthesizes and shares lessons arising from Water for Women WASH in HCF projects implemented by civil society organization (CSO) partners in eight Asia-Pacific countries from 2018 to 2022, including Bhutan, Cambodia, India, Myanmar, Pakistan, Papua New Guinea, Solomon Islands and Vanuatu.
