Objective To understand the nationwide implementation of "Management specification of air cleaning technique in hospitals (WS/T 368-2012)", and provide scientific basis for the revision of the specification. Methods With stratified sampling method, 168 hospitals in 6 provinces (cities) were selected after the promulgation of the specification to investigate the formulation and revision of air purification management system, the training of air purification management, the use of air purification methods in different departments, and the maintenance of diffe-rent air purification methods. Results 162 available questionnaires were collected, 87.04% (n=141) of hospitals formulated or revised the air purification management system after the specification was promulgated, and 88.27% (n=143) of hospitals carried out air purification management training; in 2017, of 154 hospitals with operating departments, air cleaning technology was adopted in 124 hospitals (80.52%), the utilization rates of circulating air ultraviolet air disinfector in hemodialysis ward (51.00%), neonatal ward (43.37%), cardiac catheterization room (37.88%) and delivery room (37.90%) were high; cleaning and maintenance rate as well as standard replacement rate of key components of air purification equipment in hospitals were all over 90%. Conclusion The promulgation of "air specification" has played an important role in regulating the air purification management of hospitals.
