Development and validation of medical adhesive‐related skin injury risk assessment scale at peripherally inserted central catheter insertion site in oncology patients

AIMS AND OBJECTIVES: To construct a risk assessment scale for medical adhesive‐related skin injuries (MARSI) at the peripherally inserted central catheter (PICC) insertion site in oncology patients and test its reliability and validity. DESIGN: The STARD 2015 statement guided this study. METHODS: Literature research and a modified Delphi method were adopted in this study. A total of 31 experts participated in two rounds of consultation to build the assessment scale. A convenient sampling method was used to select 195 oncology patients at the PICC clinic from January to June 2022. Inter‐rater reliability was used to test the reliability of the scale. Validity was evaluated using the content validity index (CVI) and predictive validity. RESULTS: After the two rounds of consultation, the assessment scale with five dimensions and 13 primary entries and 36 secondary entries was developed, and the expert authority coefficients for both were 0.90. The inter‐rater reliability was 0.968. The CVIs of the items ranged from 0.83 to 1.00. The area under the subject's work characteristic curve was 0.757, and the sensitivity and specificity of the scale were 80.0% and 65.6%, respectively, at a cutoff score of 15.5.
