Abstract：Objective To investigate the hygienic condition of clean operating laboratories of reproductive centers and the main influencing factors in Hunan Province so as to promote the monitoring and management of environment of clean operating laboratories. Methods During 2013-2015 in Hunan Province, we conducted a survey of technical indicators (including degree of cleanness, average concentration of airborne bacteria, ventilation rate, static differential pressure, temperature, humidity, noise and operating luminance) in 35 clean operating laboratories of 7 reproductive centers under the static condition according to Architectural Technical Code for Hospital Clean Operating Department (GB50333-2013). Results The comprehensive qualified rates of environment of clean operating laboratories showed a decreasing tendency with the increasing use life of the laboratories (χ2=8.146, P=0.04). The environmental qualified rates of 1 year, 2 and ≥3 years of use life were 60%, 42.68% and 20% respectively. The qualified rate of degree of cleanness was the lowest (64.44%), followed by static differential pressure (75.56%), average concentration of airborne bacteria (81.11%), ventilation rate (84.44%), humidity (88.89%), noise (92.22%), operating luminance (92.22%) and temperature (95.56%). Regression analysis showed that the average concentration of airborne bacteria (OR=29.814, 95.0%CI:1.374-646.799, P=0.031) and ventilation rate (OR=59.271, 95.0%CI:3.141-1,118.263, P=0.006) were the main factors influencing the environmental qualitied rate of the clean operating laboratories. Conclusions The environmental qualitied rates of clean operating laboratories of 7 reproductive centers in Hunan Province during 2013-2015 were decreased with the increasing use life of the laboratories. The average concentration of airborne bacteria and ventilation rate are the major factors impacting the environmental qualified rates of the clean operating laboratories in this investigotion.
