Evidence-searching capability among health care professionals: a comparative study.

Background: Evidence-based practice is among core competencies of health care professionals (HCPs). However, the levels of evidence-searching capability may differ among various disciplines of HCPs as they receive different education and trainings for various durations in medical schools and teaching hospitals.

Methods: This study aimed to compare the evidence-searching capability among different disciplines of HCPs and identify which aspects need to be reinforced. From a teaching hospital, we recruited 80 HCPs of various disciplines and compared their evidence-searching capability by using a validated scale. To examine if sex and education levels affect evidence-searching capability, we performed a multiple linear regression analysis with collinearity diagnostics.

Results: Physicians and pharmacists performed significantly better than other disciplines in the seven formative assessment items and the summative item (all P < 0.05). No collinearity was detected between discipline and age nor level of education. Except for the 2nd formative assessment item (correlation coefficient 0.24 ± 0.12, P = 0.04), participant's levels of education did not affect evidence-searching capability. Age was associated with lower evidence-searching capability in five formative and the summative assessment items.

Conclusions: We found a better evidence-searching capability among physicians and pharmacists than other HCPs who may require more training on evidence-searching skills. Also, evidence-searching skills training should be provided to HCPs irrespective of age and education levels.
