Preliminary clinical evaluation (PCE): A transnational scoping review of current radiography practice

Image interpretation by radiographers has gained widespread recognition; however, current evidence provides very limited knowledge of the state and scope of practice transnationally. This study therefore sought to explore the current state and scope of preliminary clinical evaluation (PCE) practice to further understand international best practices in terms of policy, training and education, and practice competence of radiographers when carrying out PCE.

A comprehensive literature search was completed via federated electronic databases (EBSCOhost and Web of Science) and professional radiography platforms for journal articles and policy or practice guidance documents, respectively. Data were charted from eligible studies following screening of articles in accordance with the predefined eligibility criteria. Themes were generated using inductive narrative analysis.

Thirty-one peer reviewed articles and 5 radiography practice policy documents were identified. Over 60% of the included studies were carried out in the United Kingdom and Australia with about 60% focused on projectional radiography of the appendicular and axial skeletons. Three main themes were developed and included: scope of PCE practice and implementation; PCE proficiency indicators; factors influencing PCE participation and performance.

Gaps exist around defined scope of practice, standardisation, commenting format and compliance with policy. There is very limited evidence around PCE practice in cross-sectional imaging, thus, it is difficult to ascertain the current state and scope of practice internationally. There is a need for countries to develop standard commenting frameworks as well as enforcement of compliance. Additionally, more research is required to ascertain the competence and benefits of PCE practice within cross sectional imaging.
