Background

The volume and costs of diagnostic imaging examinations are rising (NHS England 2016). Therefore, there is a need
to ensure that the maximum benefit is extracted from these resources. Benefits management literature suggests that the initial
step for benefits realisation is identification (Bradley 2006). A literature review was undertaken to assess existing understanding
of the available benefits.

Method

A structured narrative approach was utilised in order to promote trustworthiness & dependability, whilst minimizing
bias and error. 5 databases (CINAHL, Cochrane, ProQuest, PubMed, ScienceDirect) were interrogated using search terms
identified through application of the SPIDER tool: The returned literature was screened for quality and content using
predefined inclusion and exclusion criteria.

Results

After screening, n=519 papers were returned and categorized as follows:
• Primary benefits (n=470). These are benefits extracted from the image which align with the rationale for acquisition (e.g.
detection). These benefits tend to accrue directly to clinical stakeholders and patients by extension.
• Secondary benefits (n=63). These are benefits unrelated to the rationale for acquisition. They were categorised as being
educational (e.g. promoting understanding) or relational (e.g. promoting communication, engagement, or trust) in nature.
These benefits may accrue to a wider group of stakeholders, e.g. patients or carers.

Conclusion

There is currently limited evidence in the literature of appreciation of secondary benefits. This lack of recognition
means that some of these benefits may not be realized. There is a need, therefore, for further work to identify these benefits, if
they are to be accessible for all stakeholders.
