Abstract:
OBJECTIVE To investigate the current status of air quality in clean operating rooms in Xi'an and explore the possible influencing factors,thus to provide data support for improving the quality of operating room manage-ment.METHODS According to GB50333-2013"Architectural technical code for hospital clean operating depart-ment",on-site monitoring was conducted from 2017 to 2021 on the air quality of 242 clean operating rooms in 41 hospitals in Xi'an,and the results were compared and analyzed.RESULTS Among the operating rooms being sur-veyed,130 were from secondary hospitals,112 from tertiary hospitals;seventy-nine were ClassⅠoperating rooms,26 were ClassⅡ,137 were ClassⅢ.The pass rate for settling bacterial was 98.35%,with 94.94%for ClassⅠoperating rooms,which was significantly lower than that in ClassⅡand ClassⅢ operating rooms(χ2=6.565,P=0.022).The pass rate for dust particles was 69.01%,with 43.04%for ClassⅠoperating rooms,and there was significant difference among different levels of operating rooms(χ2=37.304,P<0.001).The pass rate for dust particles in tertiary hospitals was 61.61%,lower than that in secondary hospitals(75.38%;χ2=5.340,P=0.021).The pass rate for dust particles≥0.5μm and≥5μm were 85.12%and 74.79%,respectively.Among the operating rooms with unqualified dust particles,those with both≥0.5 μm and≥5 μm dust particles not meeting standards accounted for 29.33%,and those with only≥0.5 μm dust particles not meeting standards accounted for 18.67%.Multivariate logistic regression analysis showed that influencing factors for air quality in clean operating rooms included the year of monitoring and the level of the operating room,while the sampling area and hospital level were not statistically associated with the outcomes.CONCLUSION The overall air quality of op-erating rooms in Xi'an is not optimistic,the pass rate is affected by the year of monitoring and the clean levels of the operating rooms,indicating a need to strengthen routine management and monitoring of clean operating rooms.
