ABSTRACT
OBJECTIVE: To evaluate the status of contamination with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) in isolation wards of Huoshenshan Hospital so as to provide scientific basis for developing reasonable strategies of management of environmental health in isolation wards of COVID-19. METHODS: From Mar 9, 2020 to Mar 29, 2020, the samples were systematically collected from 2 common isolation wards that were randomly selected from Huoshenshan Hospital. The sampling objects included environmental samples, samples from personal protective equipment(PPE) of medical staff and samples from hands of medical staff. The samples were collected by cotton swab wiping method, SARS-CoV-2 nucleic acid testing was performed by real time fluorescence quantitative polymerase chain reaction, and the testing results were colleted and analyzed. RESULTS: A total of 244 samples were collected. SARS-CoV-2 nucleic acid testing showed that 1 sample that was collected from bedrail of a patient was tested positive among 171 environmental samples, with the positive rate 0.58%;all of the samples that were collected from PPE of 49 medical staff were tested negative;1 sample that was collected from the hands of a patient was tested positive among 24 samples that were collected from hands of patients and medical staff, with the positive rate 4.17%. CONCLUSION: It is an effective way to reasonably plan for layout of isolation ward and isolation procedure and rigidly implement the systems of environmental disinfection and hand hygiene so as to reduce the degree of contamination with SARS-CoV-2 in isolation wards, cut off the transmission routes of the virus and reduce the risk of exposure to nosocomial infection, meanwhile, it is necessary to strengthen the personal hygiene management during prevention and control of COVID-19.
ABSTRACT
OBJECTIVE: This study investigated the use of goggles by medical staff in the forefront of combating new coronavirus pneumonia epidemic, in order to explore safer and more effective use of goggles to provide protection for medical staff to protect themselves. METHODS: From Mar. 27, 2020 to Mar. 29, 2020, the Department of Infection Control of Wuhan Huoshenshan Hospital conducted an online questionnaire survey on 310 front-line medical staff who had been working in the hospital for 55 days by using the questionnaire Star software. RESULTS: There were many kinds of goggles in the hospital. The time for medical staff to wear goggles continuously was mainly 5-6 hours (48.71%) and 3-4 hours. Most medical staff believed that goggles without holes on edge were safer (61.94%), and wearing goggles with side holes would increase the risk of eye infection (81.94%). Most medical staff used goggles correctly, they adjusted the tightness of the strap immediately after wearing goggles(71.94%), adjusted the headband to an appropriate tightness (90.97%), and performed anti-fog treatment on the lenses before wearing goggles (99.35%), checked for damage before using goggles (94.19%). Physical discomfort during work was mainly due to fogging of the goggles to block the sight (90.32%), followed by headache (60.97%). The effective duration of fogging of protective eyepieces was mostly 2-4 hours (39.68%) and 4-6 hours (32.26%). Most medical staff believed that wearing lighter (98.71%), softer (94.52%), larger lenses and wider frame (96.45%) goggles was more comfortable. The application of transparent hand sanitizer was the highest recommended anti-fog method for goggles (46.13%), followed by the anti-fog agent method(23.55%). The best anti-fog effect could reach more than 6 hours (4.52%). CONCLUSION: Goggles were the key barrier for protection of new coronary pneumonia infection. Hospitals should attach great importance to the use of safe and comfortable goggles under conditions and anti-fog treatment to improve their own safety and improve work quality and efficiency.
