Objective      To establish a risk assessment index system of peripherally inserted central catheterization (PICC) complications

and provide a scientific basis for risk assessments before placing PICC.       Methods      Preliminary framework and indicators were formulated based on literature review

Meta analysis

conversation and questionnaire. By Delphi approach

the risk assessment indexes were made into table questionnaire

and expert consultation was conducted. Importance of the risk assessment indexes were scored. Weights were determined by Excel 2015 and SPSS 21.0.       Results       A preliminary PICC complication risk assessment index system including 4 first-class indexes and 41 secondary-class indexes was established based on the main factors of PICC complications. The first-class indicators included basic situation of patients (16 secondary indicators)

inserted body condition (12 secondary indicators)

vessel and catheter selection (8 secondary indicators) and patient compliance (5 secondary indicators).       Conclusion      The risk assessment index system of PICC complications before placement is basically established to assess the complication risk

so as to prevent and reduce the incidence of PICC complications.
