Research On Precise Prevention And Control Countermeasures Of Hospital Infection Based On The Status Of Multi-drug Resistant Bacteria Nosocomial Infection Monitoring

Objective:By analyzing the case data of patients with nosocomial infection of multi-drug-resistant bacteria in a third-class A hospital in Nanchang City and the questionnaire on the knowledge and practice of nosocomial infection prevention and control of multi-drug-resistant bacteria among medical staff,the current situation of nosocomial infection of multi-drug-resistant bacteria,the awareness rate of medical staff on nosocomial infection prevention and control knowledge,the enthusiasm and compliance of medical staff on nosocomial infection prevention and control behavior were understood.According to the current situation of multidrug-resistant bacteria nosocomial infection in the study hospital and the prevention and control status of medical staff,countermeasures and suggestions were put forward to provide reference for hospital infection management personnel.Methods:The multi-drug-resistant bacteria prevention and control report card of a hospital infection real-time monitoring system in Nanchang City from 2017 to 2021 was collected by retrospective analysis method,and the data of the multi-drug-resistant bacteria prevention and control report card verified by hospital infected personnel were manually input into Excel software,and the status of multi-drug-resistant bacteria nosocomial infection was described and analyzed.Questionnaire survey was used to investigate the knowledge of prevention and control of hospital infection of multi-drug resistant bacteria among medical staff,and the questionnaire data of prevention and control of hospital infection were statistically described and analyzed.Results:(1)Nosocomial infection of multi-drug resistant bacteria: From January 1,2017 to December 31,2021,a total of 208,411 inpatients were hospitalized in sample hospitals,among which 1686 inpatients were infected with multi-drug resistant bacteria in hospital,with an average annual incidence of 0.81%.The nosocomial infection rate of multi-drug resistant bacteria showed an increasing trend from 2017 to 2021.From 0.39 percent in 2017 to 1.36 percent in 2021.Most of the infected people were elderly patients with a long hospital stay.The departments with high incidence of multidrug-resistant bacteria in hospital were intensive care(51.22%),brain surgery(8.33%),emergency department(5.45%)and geriatric medicine(3.27%).The main nosocomial infection sites of multidrug-resistant bacteria were lower respiratory tract(35.29%),pneumonia(20.64%)and urinary tract(9.49%).Baumann/Acinetobacter hemolyticus had the highest detection rate in the hospital(81.93%).(2)Investigation on knowledge of nosocomial infection prevention and control of multi-drug-resistant bacteria among medical staff: A total of 557 questionnaires were collected,among which 550 were effective,with an effective rate of 98.74%.According to the survey results,413 women and 137 men were surveyed.The age group from 31 to 40 was the highest,accounting for 46.50%.Among the respondents,the number of surgery accounted for the most,44.2%;66% of respondents had a bachelor’s degree;Most of them have worked for 11～20 years,accounting for 28% of the total.Nursing staff accounted for 54.20% of the respondents.The results showed that gender,age,years of employment,education,post,training times and department leaders’ attention had statistically significant differences in the scores of prevention and control knowledge(P<0.05).There were significant differences in the scores of medical staff’s position,professional title,training times and leaders’ attention on prevention and control attitude(P<0.05).Gender,age,department,years of employment,education,post,title,training times and department leaders’ attention had statistically significant differences in the scores of prevention and control behaviors(P<0.05).Conclusion:(1)The nosocomial infection rate of multidrug-resistant bacteria in this hospital showed an increasing trend,which may be related to old age and long hospital stay.In order to reduce the incidence of infection,it is necessary to strengthen the active surveillance and monitoring of key departments,especially the monitoring of key populations,and strengthen the frequency of disinfection in the environment of key departments and key populations,so as to achieve early detection,early diagnosis,early adoption of disinfection and isolation measures,and reduce the occurrence of iatrogenic cross infection.(2)Differences in hospital infection prevention and control questionnaire scores of medical staff were related to gender,age,years of employment,education,post,training frequency and department leaders’ attention.Strengthen the publicity and training of multi-drug resistant bacteria nosocomial infection knowledge for medical staff,and evaluate the content of publicity and training.By improving the awareness of prevention and control enthusiasm of medical staff,enhancing the sense of responsibility of medical staff,improving the compliance of prevention and control behavior of medical staff,better improving the quality of medical treatment,protecting the safety of patients to the greatest extent,and reducing the consumption of medical resources.(3)Strengthen the detail monitoring and refine the work process.Establish a multidisciplinary management team to supervise clinical departments regularly or irregularly,especially to monitor the details of the implementation of prevention and control measures,and to summarize and improve the inspection situation quarterly.Work procedures should be refined to strengthen the implementation of prevention and control measures for medical personnel.
