Using Work Domain analysis to analyse perfusionists’ conceptualisation processes during routine andfailure cardio-pulmonary bypass scenarios: Preliminary outcomes using Markov chain analysis

摘要

Cardio-pulmonary bypass (CPB) involves the maintenance of whole body perfusionduring cardiac surgery. While CPB is safe, emergencies do occur and perfusionists areexpected to respond appropriately. However, perfusionists’ training programs appear tobe underdeveloped. In addition, there appears to be little understanding about howperfusionists conceptualise their work domain. This paper presents a work domainanalysis-based (WDA) protocol for analysing perfusionists conceptualisations. A WDAof the CPB is presented. A hi-fidelity simulation environment with a video-cued recallinterview data collection protocol is described and a Markov Chain analysis of verbalprotocols is outlined using two participant data sets. We conclude that with furtherparticipant data analysis this novel approach offers promising insights intoconceptualisation processes and exposes addition procedural, organisational andengineering issues that may need to be included in curriculum development.
