Objective  To construct a scientific and rational post competency model of human organ donation coordinators.

  Methods  Based on the onion model, the index pool was initially constructed by literature research and behavioral event interview. The index system was screened, modified and improved using Delphi method. The weight of indexes at all levels was determined by analytic hierarchy process.

  Results  The effective response rates of two rounds of Delphi expert inquiries were both 100%, indicating that the expert opinions were highly dependable. The experts' judgment coefficient (Ca), familiarity (Cs) and authoritative coefficient (Cr) were all above 0.7, indicating that the experts' opinions were highly reliable. The expert coordination coefficients (W) were 0.294 and 0.342 (both P<0.001), indicating that experts delivered coordinated opinions and yielded slight difference in understanding the importance of indexes. Finally, according to the "onion model" theory and experts' opinions, a set of coordinator's post competency model including 6 first-level and 55 second-level indexes was established, which comprised an index surface layer, a middle layer and a core layer. Among them, the core layer represented core professional values, the middle layer was personal quality and professional ethics and quality, and the surface layer was interpersonal communication capability, organizational cooperation capability and professional knowledge and lifelong learning capability.

  Conclusions  The post competency model of organ donation coordinators established in this study consists of 6 first-level and 55 second-level indexes, which is highly effective and reliable.
