Evidence-based decision-making in nursing - development and piloting of a train-the-trainer concept for teachers at schools for health care professionals: A pilot study.

BACKGROUND: Train-the-trainer concepts (TTT concepts) to impart evidence-based practice competences aim at promoting the implementation of evidence-based practice. The aim of this study was to develop and pilot-test a TTT training program for teachers at schools for health care professionals. The program is based on the core curriculum "Evidence-based Decision-making" set up by the German Network for Evidence-based Medicine e.V. (DNEbM). METHOD: The study was conducted according to the UKMRC framework for complex interventions and consisted of Phase 1 (Development) and Phase 2 (Piloting). In Phase 1, the intervention was modelled on the basis of a systematic literature search. In Phase 2, the TTT concept was piloted with teachers at two schools for health care professionals. For the evaluation, short interviews with the participants were carried out after each module; classroom observations took place during the training and were followed by a focus group interview. In addition, baseline characteristics were collected prior to the training and descriptively evaluated. Critical health competence was surveyed using the Critical Health Competence Test (CHC test) before and after the course. The questionnaires, interviews and classroom observation protocols were processed according to Mayring's qualitative content analysis. Person parameters ±SD were calculated to determine the level of competence. RESULTS: Piloting took place in September 2018 and from September to November 2019. Eight teachers from two training institutions participated. The evaluation of the focus group interviews and the classroom observation protocols resulted in a category system comprising 6 main and 17 subcategories. The feasibility of the materials and methods could be demonstrated in both pilot tests. Reactivation and extension of prior knowledge were confirmed by the participants. The small group size was appreciated; the participants took an active part during the lessons and were stimulated to plan their own lessons. The evaluation of the CHC test revealed average person parameters of 432 ± 45 (pretest, n=8) and 512 ± 65 (posttest, n=8). DISCUSSION: Using mixed methods, the results show the feasibility of the curriculum. CONCLUSION: Further evaluation in a randomized controlled trial (RCT) is needed to prove the efficacy of the curriculum.
