RESUMEN
【Objective】 To understand the current status of medical staff’s awareness of hospital infection prevention and control during the epidemic of COVID-19 in Shaanxi Province and analyze its influencing factors. 【Methods】 The questionnaire was designed on the "Questionnaire Star" website. Based on the WeChat platform, a voluntary sampling method was used to invite online questionnaires. From March 13 to 29, we collected a total of 8037 questionnaires, 30 of which did not meet the requirements and had logical problems, and finally 8 007 valid questionnaires were obtained. 【Results】 A total of 8 007 medical staff were surveyed. Among them, Medical staff of Grade 3A, Grade 3B, Grade 2A, and Grade 2B hospital accounted for 39.6%, 2.3%, 55.3%, and 2.6%, respectively. The average age of the respondents was (32.1±7.2) years old, including 7 199 nurses and 501 doctors. The training effect was statistically significant in different regions, different hospital levels, whether it was a designated hospital and whether there were sensor control supervisors, as well as medical staff of different specialty, professional title, and work area (all P<0.01). The basic cognitive situation of the surveyed subjects showed that most medical staff in Shaanxi Province had a correct rate of less than 30% in whether they needed to disinfect before de-protection and how to disinfect the hospital environment. Multivariate linear regression analysis showed that the cognition level of medical staff in Grade A hospitals was significantly lower than that in Grade A hospitals (P<0.01). The cognition level of medical staff in designated hospitals was significantly higher than that of others (P<0.01). The cognition level of medical staff in hospitals with sensory control supervisors was significantly higher than that of others (P<0.01). The cognition level of people aged 25-34 and 35-44 was significantly lower than those aged 45 and above (all P<0.01). The cognition level of medical technicians and service personnel was significantly lower than that of doctors (P=0.02 and <0.01, respectively). The cognition level of medical staff with intermediate, associate senior, and senior professional titles was significantly higher than the cognition level of those with junior and below professional titles (all P<0.01). The cognition level of medical staff in fever clinics, emergency departments, isolation wards, ICU and other surgeries was significantly higher than that of those working in ordinary outpatient department (P=0.01, 0.03, <0.01, 0.02, and <0.01 respectively). 【Conclusion】 Most medical staff in Shaanxi Province have misunderstandings about whether they need to disinfect before de-protection and how to disinfect the hospital environment. Moreover, we found that the awareness of medical staff in Shaanxi Province of hospital infection prevention and control during the epidemic of COVID-19 was affected by the hospital’s level, whether it was a designated hospital, whether there were sensor control supervisors, as well as the age, specialty, professional title and work area of the medical staff.
RESUMEN
Objective:To understand general hospital medical staff status quo and characteristics of blood -borne occupational exposure , analysis its ethics factor , to make the prevention countermeasures of blood -borne oc-cupational exposure to provide scientific basis .Methods:From January 2013 to December floor all the medical staff of blood -borne occupational exposure cases were retrospectively analyzed .Results:A total of 101 medical staff blood-borne occupational exposure , which is given priority to with the nurse , accounted for 60 .40%;More con-centrated in under 30 employees, accounted for 70.29%;Occupational exposure personnel distribution in the ma-jority with surgical department (42.57%), followed by the physician (36.63%);Wards (60.40%), the operat-ing room (15.84%) and therapy (11.88%) are the sites of occupational exposure often happen;Sharp injury in the composition of the ratio of 87.12%, in the first place, in which a proportion (23.76%), pull out the needle (18.81%) and blood (15.84%), surgical suture (14.85%) and transfusion injection (13.86%) as the sharp injury of frequent occurrence of occupational exposure;Exposure is given priority to with hepatitis b ( 61 .38%) . Conclusion:Medical staff blood-borne occupational exposure risk is high , the hospital infection control personnel must pay attention to occupational exposure of the whole education , strengthen the administration of the occupation-al exposure of ethics , reduce the risk of occupational exposure and injury .
RESUMEN
Objective To investigate cognitive status and influencing factors for hand hygiene(HH)among health care workers(HCWs),and provide basis for scientific management of HH.Methods In April 2013,HCWs in a general hospital were selected by randomly sampling method,questionnaires were used to survey the implementation of HH in recent one month and HCWs’cognition on knowledge about HH.Results A total of 750 HCWs were in-vestigated,652 available questionnaires were collected.The frequency of hand washing and hand disinfection per day among most HCWs were 10 - 19 times,accounting for 46.62% and 47.85% respectively;30.52% of HCWs washed their hands for ≥30 seconds each time,60.58% of HCWs dried hands with paper towel after washing hands,57.21 % of HCWs abided by six-step hand washing method.The overall correct rate of cognition on ten op-portunities that requiring HH in clinical practice was 68.68%.The main factors influencing the implementation of HH were as follows:skin irritation of hand sanitizer and hand disinfectant subjectively considered by HCWs (63.34%),inadequate hand washing facilities(41 .10%);high cost of hand sanitizer ,hand disinfectant,and dry paper towel (38.96%),et al.Conclusion In addition to intensifying education on HH,installing rational HH facili-ties and improving HH standard are key points in strengthening HH in general hospital.
