Abstract: Ｏｂｊｅｃｔｉｖｅ：To develop an investigation form for hemodialysis infection outbreak, and identify sources of the outbreak in the early stage.
Ｍｅｔｈｏｄｏｌｏｇｙ：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 15 specialists.
Ｒｅｓｕｌｔｓ：A total of 87 studies of hemodialysis infection outbreak were eligible for inclusion. The mean of authority coefficient (Cr) was 0.850. Kendalls W coefficient of the specialist consultation was 0.351 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.
Ｃｏｎｃｌｕｓｉｏｎ：The investigation form can be used in the early stage of cluster of investigation of hemodialysis infection clusters to provide a reference for identifying potential sources of infection, However, the external applicability of the form needs to be further evaluated.
