Abstract:
OBJECTIVE To evaluate the status of microbial contamination in the environment of respiratory tract specimens sampling rooms and observe the association of the factors such as design and layouts of the sampling rooms with the potential risk of infections in the environment so as to provide scientific bases for optimizing the construction standards of fever clinics of the medical institutions.METHODS The sampling rooms of fever clinic were chosen from 10 tertiary or above medical institutions of Hangzhou,and the samples were collected from the key sites such as air,object surfaces and hands of health care workers.The respiratory tract pathogens in the sam-ples were detected by FilmArray full-automatic medical PCR analysis system,and the pathogens in the samples were detected by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry(MALDI-TOF MS).The data including the areas,windows,mechanical ventilation facilities,physical partitions,frequencies and modes of disinfection and daily amounts of diagnosis and treatment of the 10 sampling rooms were investigated,and the univariate analysis was performed for their association with the microbial contamination of environment.RESULTS The isolation rate of respiratory tract pathogens was 10.00％(4/40),respiratory syn-cytial virus,human rhinovirus and adenovirus were dominant among the respiratory tract pathogens.The isolation rate of bacteria was 71.88％(23/32),Staphylococcus ho minis and Staphylococcus epidermidis were the major species of opportunistic pathogens isolated.The result of univariate analysis indicated that both the presence of windows(P=0.012)and mechanical ventilation facilities(P=0.047)were associated with the potential risk of infections in the environment(P＜0.05);while the factors such as the areas of sampling rooms,physical parti-tions,disinfection modes and daily amounts of diagnosis and treatment were not remarkably associated with the potential risk of infections in the environment.CONCLUSION It is an effective way to physically separate the air-flow from other areas or fix the mechanical ventilation facilities to create proper airflow during the construction of fever clinic sampling rooms so as to reduce the potential risk of infections in the environment of sampling rooms.
