RESUMO
Objective To study the compliance and correctness of hand hygiene(HH)of staff in intensive care units(ICUs)of a tertiary first-class hospital,and provide theoretical basis for HH intervention.Methods In April 2023,staff in 17 ICUs of this hospital were performed on-site survey by infection control staff,and monitoring forms about HH compliance and correctness were filled out.Results A total of 874 HH opportunities were ob-served with the concealed observation method,501 HH opportunities were implemented,the compliance rate was 57.32%,273 HH opportunities were correctly implemented,with an correct rate of 54.49%.The compliance and correct rate of HH among staff in different ICUs varied significantly.Compliance and correct rates of HH among staff with different jobs were statistically different:HH compliance rate of cleaners(31.97%)was lower than that of nurses(63.83%),doctors(58.77%)and other personnel(58.14%);HH correct rate of cleaners(30.77%)was lower than that of nurses(58.17%).The causes for not implementing HH among staff with different jobs and at different HH opportunities were statistically different:the rate of not implementing any HH measures after con-tact with patients(84.75%)was higher than before contact with patients(41.27%),before clean and sterile ma-nipulation(30.00%),as well as after contact with blood and body fluid(45.45%).The rate of not implementing any HH measures after contact with the patient's surrounding environment(66.67%)was higher than before con-tact with patient as well as before clean and sterile manipulation.The rates of incomplete HH steps and insufficient HH time among staff with different jobs were statistically different:The rates of incomplete HH steps of other per-sonnel(82.35%)was higher than that of doctors(52.63%).The rates of insufficient HH time of doctors(82.46%)and nurses(78.18%)were higher than that of cleaners(51.85%).Conclusion The implementation of HH among different occupational groups and at different HH implementation opportunities in ICU is significantly different,which should be intervened based on their characteristics.
