An Evidence-Based Approach to Influencing Evidence-Based Practice in Allied Health

Factors affecting the evidence-based practice (EBP) capabilities of allied health staff are complex and are linked with institutional barriers, personal self-belief, and individual experience and ability. This study's aim was to measure the effect of training and organisational change on EBP measures among allied health staff.

Sixty-three percent of allied health hospital staff (201/303) completed an online survey measuring constructs of EBP. Results were compared to those from the same survey conducted in the previous year, with a response rate of 72.2% (182/252). Eighty staff completed the survey at both time points. Independent and repeated measures ANOVAs were used to compare levels of self-efficacy, outcome expectancy, knowledge, and use, according to discipline over time.

A significant increase in EBP self-efficacy was observed over time (p=0.03), as well as amongst staff who completed the survey at both time points (p=0.013). Significant differences existed between professions at time 2 in EBP-outcome expectancy (p=0.002) and EBP use (p=0.016).

Targeted within-department and general allied health workplace evidence-based interventions to improve EBP constructs have been effective at improving overall allied health EBP self-efficacy. Different departments have demonstrated individual improvements in EBP scores, potentially reflecting different training and organisational strategies implemented across departments.
