Abstract

Introduction: Evidence-based nursing and self-efficacy are significant factors behind quality care delivery in critical care units. Aim: This study aimed to assess the effects of an evidence-based nursing training workshop on critical care nurses' self-efficacy. Methods: This two-group pretest-posttest quasi-experimental study was undertaken in 2016 in two large-scale hospitals in Tehran, Iran. The participating nurses from one hospital were purposefully allocated to the intervention group and the other hospital's participants comprised the control group. A convenience sample of 45 nurses was selected from each hospital. For nurses in the intervention group, an evidence-based nursing training workshop was held in four two-hour sessions on two successive days, while the nurses in the control group received no specific evidence-based nursing training. Findings: After the intervention, these values increased to 51.1 +/- 2.49 and 61.6 +/- 2.05, respectively. The increase in the intervention group was statistically significant (P = 0.001), while the increase in the control group was insignificant (P = 0.06). Thus, the posttest mean score of self-efficacy in the intervention group was significantly greater than the control group. Conclusion: Evidence-based nursing training significantly improves the nurses' self-efficacy. Therefore, healthcare policy-makers and authorities are recommended to provide nurses with in-service and evidence-based nursing training programs.
