Construction of a postoperative infection outbreak investigation form: A tool for early detection and control measures.

BACKGROUND: To develop an investigation form for postoperative infection outbreak (PIO), and to identify sources of the outbreak in the early stage. METHODS: After an exhaustive literature review, we used the Delphi method to determine the indicators and relative risk scores of the assessment tools through 2 rounds of specialist consultation and overall consideration of the opinions and suggestions of 20 specialists. RESULTS: A total of 203 studies of PIO were eligible for inclusion. The mean authority coefficient (Cr) was 0.87. Kendall's W coefficient of the specialist consultation was 0.704 after 2 rounds of consultation (P < .005), suggesting that the specialists had similar opinions. Based on 4 primary items and 19 secondary items of the source of PIO, and tripartite distribution characteristics of infected patients, we constructed the PIO investigation form. CONCLUSIONS: The PIO investigation form can be used in the investigation of the early-stage cluster of cases, it's a prerequisite for taking effective control measures, avoiding PIO occurrence. However, the effect of the investigation form needs to be further evaluated.

Development of an Investigation Form for Hemodialysis Infection Outbreak: Identifying Sources in the Early Stage.

OBJECTIVE: To develop an investigation form for hemodialysis infection outbreak, and to identify sources of outbreak in early stage. METHODS: After an exhaustive literature review, we used the Delphi method to determine the indicators and relative risk scores of the assessment tools through two rounds of specialist consultation and overall consideration of the opinions and suggestions of 18 specialists. RESULTS: A total of 87 studies of hemodialysis infection outbreaks were eligible for inclusion. The mean authority coefficient (Cr) was 0.89. Kendall's W coefficient of the specialist consultation was 0.359 after two rounds of consultation (p <0.005), suggesting that the specialists had similar opinions. Based on 4 primary items and 13 secondary items of the source of hemodialysis infection outbreak, and tripartite distribution characteristics of infected patients, we constructed the investigation form. CONCLUSIONS: The investigation form can be used at the early stage of the cluster of cases, it's a prerequisite for taking effective control measures, avoiding hemodialysis infection outbreak occurrence. However, the effect of the investigation form needs to be further evaluated.
