Construction of an evaluation index system of core competencies for critical care blood purification nurses in China: A Delphi study

Aim: The purpose of this study was to construct a core competencies evaluation index system for critical care blood purification nurses in China. Background: While nursing is an integral part of critical care blood purification treatment, there are no established indicators to evaluate the core competencies of critical care blood purification nurses. Design: A Delphi study. Methods: An initial draft of the competencies evaluation index system for critical care blood purification nurses was developed through a literature review and semi-structured interviews. From February 2023 to March 2023, a two-round Delphi survey was conducted to consult with 18 experts in the field of critical care blood purification from eight provinces in China to rate the importance of each item and propose modifications to the evaluation index system. Results: The effective questionnaire recovery rates in two rounds of expert consultation were 94.4 % and 94.1 % and the average expert authority coefficients were 0.88 in both rounds. The core competencies evaluation index system of critical care blood purification nurses consisted of 39 items in five domains, namely theoretical knowledge, practical skills, professional development capability, critical thinking ability and personal qualities and attributes. The Kendall's W coefficients for the first- and second-level indicators were.21 and.20 in the first round and.23 and.25, respectively, in the second round of consultations (p <.01). Conclusion: The core competencies evaluation index system of critical care blood purification nurses is scientific and reliable and can provide references for the recruitment, training and management of critical care blood purification nurses.
