Objective To investigate the current status and influencing factors of hand hygiene practices among primary healthcare workers， and to provide a reference for improving hand hygiene behavior in primary healthcare institutions.
Methods A self-designed questionnaire was used to conduct a survey among medical staff of seven community health service centers in Jiading District， Shanghai， using a cluster random sampling method. The data collected were subjected to descriptive statistics， reliability and validity tests， correlation analysis， and structural equation model fitting.
Results A statistical difference in hand hygiene compliance was found among medical staff with varying occupational types and educational levels （P<0.05）， and medical staff in clinical departments exhibited higher levels of hand hygiene compliance （P<0.05）. In the health belief model， among the core variables， healthcare workers’ perceived benefits， perceived barriers， and self-efficacy had a direct impact on hand hygiene behavior， with direct effect values of 0.341， -0.152， and 0.234， respectively. Meanwhile， cues to action and perceived severity of COVID-19 infection indirectly affected hand hygiene behavior， with an indirect effect value of 0.066 and 0.062， respectively.
Conclusion Healthcare workers generally exhibit a high degree of hand hygiene compliance， but there are variations in hand hygiene scores among healthcare workers with different characteristics. Enhancing healthcare worders’ perception of benefits， action cues， and self-efficacy while reducing perceived barriers can effectively improve their hand hygiene behavior.
