The development and validation of a standardised eight-station OSCE for registration of undergraduate nursing students: A Delphi study

Abstract

AimTo develop and validate a set of OSCEs for use as a nationally applicable final exam of undergraduate nursing students’ clinical and professional competencies. BackgroundTertiary recommendations for nursing registration require student achievement of a prerequisite level of both nursing knowledge and skill. Assessment of nursing skills prior to provision of nursing registration is an increasingly important focus of university nursing education. Objective Structured Clinical Examinations (OSCEs) are an appropriate tool for assessing the competencies of nursing students, but the mode and content of OSCEs varies widely. Thus, for nationally-based registration, development of a standardized set of OSCEs to determine the clinical competence of nursing students is important. DesignA modified Delphi study, informed by a systematic scoping review of relevant literature. MethodsA two-phase study was conducted. Initially, a scoping review was conducted to establish internationally agreed competences for graduating nursing students. These were included in an online questionnaire send to national experts to develop a validated and accepted nursing competency framework and associated implementation strategies. This was round 1 of a three-round modified Delphi study. A Content Validity Index (CVI) was calculated and thematic analysis was used to analyze the experts’ opinions. ResultsDetails of a set of OSCEs for final exam of undergraduate nursing students were developed and validated. These OSCEs included nine competencies addressed in eight 10-minute stations. ConclusionA ‘best-practice’ OSCE evaluation system, designed from both international literature and the opinions of nation-wide experts was achieved. This well-designed OSCE was shown to be a reliable and valid method for assessing the clinical competence of nursing students. It reflected global procedures as well as the local conditions and Iranian expectations. The results of this study can be used by nursing schools across the country. They can also be used to model equivalent development of locally relevant OSCEs in countries around the world.
