A peer learning intervention in workplace introduction - managers' and new graduates' perspectives.

Background: Evaluation of a complex intervention are often described as being diminished by difficulties regarding acceptability, compliance, delivery of the intervention, recruitment and retention. Research of peer learning for nursing students have found several positive benefits while studies of peer learning for newly graduated nurses are lacking. This study aimed (1) to investigate the study process in terms of (a) first-line managers' perspectives on the intervention study, the difficulties they face and how they handle these and (b) new graduates' fidelity to the intervention and (2) to examine the effect of the peer learning intervention in workplace introduction for newly graduated nurses.

Methods: A mixed-methods approach using semi-structured interviews with eight managers, repeated checklist for fidelity and questionnaires conducted with 35 new graduates from June 2015 and January 2018, whereof 21 in the intervention group. The peer learning intervention's central elements included pairs of new graduates starting their workplace introduction at the same time, working the same shift and sharing responsibility for a group of patients for 3 weeks. The intervention also included 3 months of regular peer reflection.

Results: Managers offered mostly positive descriptions of using peer learning during workplace introduction. The intervention fidelity was generally good. Because of recruitment problems and thereby small sample size, it was difficult to draw conclusions about peer learning effects and, thus, the study hypothesis could either be accepted or rejected. Thereby, the study should be regarded as a pilot.

Conclusions: The present study found positive experiences of, from managers, and fidelity to the peer learning intervention; regarding the experimental design, there were lessons learned.
