Preliminary clinical evaluation: Where are we? An international scoping review

The College of Radiographers' vision was that diagnostic radiographers in the UK would be writing preliminary clinical evaluations (PCE) on images. Their 2013 policy supporting the use of PCE has not been updated in a decade and it might be suggested PCE practices in the UK have not really moved on, though elsewhere it appears to have gained traction. The aim of this scoping review was to establish the current global status of the use of PCE.

The Arksey and O'Malley scoping review framework and PRISMA-ScR guidelines were used to develop a protocol to identify studies between January 2013 to January 2024 using six databases. Collated literature was analysed using content analysis to identify themes.

52 relevant studies were identified for inclusion. Studies focused predominantly on evaluating accuracy, education, perceptions, and new initiatives. Themes identified a developing role in the use of PCE internationally, perhaps more than in the UK, and in a range of modalities and clinical settings though projectional radiography remains the mainstay. Barriers and drivers to the use of PCE were identified in addition to some quality mechanisms used to support PCE implementation, though impact of implementation was not well explored.

Considering PCE has been an aspiration for more than a decade, it remains relatively infrequently researched. There is growing scope internationally, particularly in Australia, yet there is no real evaluation of the impact and role that PCE may have.

Until further research into the potential impact of PCE and barriers to its implementation, it is likely practices may not evolve with the risk AI technologies may supersede necessity for the practice.
