Background:
Nurses self-efficacy, confidence and their competency for evidence-based practice have a relevant impact in the quality of care provided to patients. However, the implementation of evidence-based practice continues to be limited to date and the relationship between these elements has not been thoroughly understood. Thus, the aim of this study was to analyze the impact on confidence levels of a teaching strategy to promote evidence incorporation into clinical decisions made by student nurses in hypothetical scenarios. Besides, students' satisfaction with the new teaching strategy was assessed.
Methods:
The teaching strategy was asynchronous, on-line and based on multiple-choice questionnaires related to decision making on an intensive care unit patient. Confidence levels were assessed by introducing the scoring tool confidence-based marking. Changes between pre- and post-tests in correct answers, confidence levels and expected-observed ranges of accuracy at each level of certainty were analyzed through non-parametric McNemar's sign tests for paired-samples differences. To assess students' satisfaction with the teaching strategy, a mixed-methods approach was followed. Descriptive statistical methods and Qualitative Content Analysis were followed respectively in order to analyze students' satisfaction.
Results:
A total of 165 students completed the assignment, 101 answered the satisfaction survey and 7 participated in the interviews. Statistically significant better scoring and higher confidence levels were found in the post-intervention. Statistically significant differences in expected-observed ranges of accuracy were found for the three levels of certainty. Students were highly satisfied with the proposed task. In the qualitative analysis one category was elaborated which illustrated the students' perceived added value of this new assignment.
Conclusions:
On-line teaching strategies based on clinical scenarios that focus on evidence-based decision-making have the potential to increase the confidence of nursing students. Additionally, interventions designed by teams incorporating clinical nurses, university librarians and academic nurses have the potential to bridge the evidence-practice gap in nursing education.
