Cost identification in health professions education: A scoping review.

BACKGROUND: Resource scarcity in health professions education (HPE) demands rigorous consideration of costs. Yet, thus far, we have been unable to completely and consistently identify the costs of HPE. To address this knowledge gap and enable use of economic evidence in decision making, a detailed overview of all existing costs and approaches to cost identification in HPE is needed.

OBJECTIVES: This review summarises the diversity of costs, cost perspectives and cost identification methods used in economic research of HPE to answer the following questions: which educational topics, costs, cost perspectives and cost identification methods are being investigated in HPE literature?

METHODS: This investigation followed the Joanna Briggs Institute guidelines for scoping reviews. PubMed, ERIC, CINAHL and PsycINFO were iteratively searched for English language publications between 2012 and 2022 that reported costs of HPE. Data was extracted for study characteristics, educational context and economic methodology.

RESULTS: A total of 136 articles of original research on the costs of educating all major licence healthcare professionals were included. A diffuse interest in costs is reflected in publications from 93 distinct journals and by the diversity of educational topics and cost types explored. However, the majority of investigations failed to define the cost perspective (86, 63%) and cost identification methods (117, 86%) and did not demonstrate common reporting structure or cost terminology, all of which contribute to persistent inconsistencies in cost identification.

CONCLUSION: The source of disharmonious cost identification in HPE is fuelled by diverse interests and divergent concepts of costs and costing methodology. Left in its current state, disharmonious cost identification will continue to limit transparency, comparison and synthesis of evidence, hamper objectivity in implementation and policy decisions and impede the efficient and sustainable allocation of resources. A research agenda must be developed, prioritised, and validated by the broader community to develop a theoretical framework for HPE cost research, define stakeholders, elicit values and preferences and chart a path toward harmonised costing.
