Assessing evidence-based practice among Australian radiographers: A self-report survey

Evidence-based practice (EBP) is essential for ensuring the delivery of effective and efficient healthcare. Despite this, EBP is not always well implemented in the clinical environment. Evidence suggests that the application of EBP is likely impacted by healthcare workers' attitudes, knowledge and skills. While there has been a recent proliferation of international research examining diagnostic radiographers' attitudes towards, knowledge of and skills in EBP, no such research exists in an Australian context.

This study presents the results of a validated self-report survey, the evidence-based practice questionnaire (EBPQ), administered to Australian diagnostic radiographers. The data were described and aggregated means were calculated for each of the domains. Inferential statistical tests were computed, including Cronbach's alpha, Pearson's correlations and independent t-tests, and Kruskal-Wallis tests.

The aggregated mean for the practice domain was 5.02 (SD 1.104), for the attitudes domain it was 5.41 (SD 1.169), and for the knowledge and skills domain, it was 5.20 (SD 1.177) on a seven-point scale. Significant associations were identified among these domains, with individuals holding higher qualifications and occupying leadership positions more likely to score higher. Additionally, the modality in which an individual primarily practiced appeared to also have an impact on their score. However, no significant correlation was found between any domain and the number of years an individual had been practicing.

This research has established a baseline of Australian diagnostic radiographers' practices, knowledge skills and attitudes towards evidence-based practice.

This baseline can inform the development of interventions aimed at enhancing the role of evidence-based practice in the sampled population.
