Assessment of sanitation facilities in primary healthcare institutions across seven provinces in China: a cross-sectional study

China's policy initiatives have improved sanitation facilities within primary healthcare institutions, but gaps persist in essential components and maintenance. Continued efforts are needed to enhance sanitation infrastructure to meet higher standards and ensure comprehensive coverage. The study's insights can inform both domestic and global strategies for improving healthcare sanitation, contributing to the achievement of international health goals. Future research should focus on identifying barriers to sanitation improvements and developing targeted interventions to standardize sanitary facilities in primary healthcare settings.
