%X Despite global recognition, WHO reports reveal significant gaps, with one in four healthcare facilities lacking basic water services, affecting over 1.8 billion people, and 21% lacking sanitation services, impacting 1.5 billion people, especially prevalent in low- and middle-income countries. This study aimed to critically evaluate the current state of water, sanitation and hygiene (WASH) facilities across a diverse range of healthcare settings. This review included various databases such as PubMed, MEDLINE, EMBASE, CINAHL, Scopus and grey literature; eligible studies employing various designs were scrutinized for WASH infrastructure and practices. Methodological quality was rigorously evaluated using the QuADS checklist. Data analysis, performed with R software, involved deriving pooled estimates of WASH intervention effects. Sensitivity analyses were conducted, employing statistical methods such as funnel plots to ensure robustness and mitigate biases. Of the 13,250 articles screened, 18 were included in this review. Meta-analyses revealed significant effect sizes for WASH interventions across domains - water (67.38%), sanitation (53.93%), waste management (40.82%), environment (56.58%), hygiene (66.83%), and management (42.30%). Widespread disparities in WASH persist across healthcare facilities, with rural areas facing notable deficits. Challenges in water quality, sanitation and waste management demand comprehensive, multi-sectoral approaches for improvement.
