Construction of an Investigation Form for Postoperative Infection Outbreak Based on Epidemiological Characteristics and Specialist Research
摘要
Abstract
Background Postoperative infection outbreak(PIO)is a concentrated manifestation of the harmfulness of hospital-acquired infections,and how to effectively control the occurrence of PIO promptly is currently the focus of infection control.At present,some infection prevention personnel lack emergency response experience and ability to investigate suspected sources of infection in the face of infection clusters.Objective To develop an investigation form for PIO,and identify the sources of infection in the early stage to prevent outbreaks.Methods From January to May 2023,Worldwide Database for Nosocomial Outbreaks(WDNO),PubMed,CNKI,and other databases were searched for studies related to PIO.Data extraction and annotation were performed.After cleaning the title and abstract text information of infection control literature downloaded from the PubMed database,a large-scale training set was constructed to build a word vector model based on the Skip-Gram method.Preliminary identification of risk factors for PIO was summarized based on the classification results of the word vector model constructed.Subsequently,15 consulting experts were invited to evaluate the importance of PIO risk factors using a modified Delphi method.The Analytic Hierarchy Process(AHP)was adopted to calculate weight and combined weight for the primary and secondary indicators to determine the possible sources of infection outbreaks.Based on this,an investigation form for PIO was constructed.Results A total of 203 PIO-related studies were finally included.A total of 15 experts were consulted by the modified Delphi method,and all the questionnaires for the two rounds of expert consultation were returned with a positive coefficient of 100.00%.The average authoritative coefficient(Cr)of 15 experts was(0.86±0.10),the average familiarity(Cs)was(0.81±0.10),and the average judgment(Ca)was(0.92±0.10).Kendall's W coefficient(Kendall's W)of concordance after two rounds of expert consultation was 0.351(P<0.005),which showed that the consensus of expert opinion was good,indicating a good consensus among expert opinions.After two rounds of the modified Delphi method,4 primary indicators and 19 secondary indicators were constructed.Within the indicator system,the weights of the 7 primary indicators ranged from 22.23%to 27.50%,and the combined weights of the secondary indicators ranged from 3.32%to 6.29%.Based on this,the PIO investigation questionnaire was developed,primarily including five aspects of patient basic information,infection status,perioperative factors,personnel,and environment.Conclusion Based on epidemiological characteristics and expert consultation,a form used for PIO investigation was constructed.The content covers the main risk factors and critical points that may lead to outbreaks,providing a reference for identifying potential sources of PIO.关键词
