Using the Delphi technique to define the clinical competencies required by newly qualified diagnostic radiographers in South Africa

Abstract

This research was performed to obtain consensus of opinion on the clinical competencies required of newly qualified diagnostic radiographers in South Africa in an attempt to improve alignment between educational practices, assessment practices and workplace requirements. Methods: The Delphi technique, an effective group communication process was employed to recruit a panel of experts representing the radiography profession in South Africa. Three rounds of structured questionnaires together with controlled feedback were sent to the panel members for comment. The same four point Likert scale was employed in all three rounds of the questionnaire. Consensus of opinion was predetermined at >75% agreement for each clinical competency. Results: Response rates for rounds I, 2 and 3 were: 84% (n=49), 78% (n=45) and 69% (n = 40) respectively. Of the 109 clinical competencies listed in the first round questionnaire, 94 (86%) achieved consensus as being necessary clinical competencies required of newly qualified diagnostic radiographers. The remainders were further investigated in terms of whether they should be excluded or included in role extension possibilities. An additional 22 clinical competencies were also suggested by the panel in round I and further developed in subsequent rounds
