This article considers the findings of a qualitative research study into the impact of simulation on the development of advanced clinical practitioners' skills and knowledge. STUDY AIM: To explore simulated learning through the eyes of trainee and trained advanced clinical practitioners (ACPs) and consider its potential in supporting their development. METHOD: This qualitative research study explored the experiences of trained and trainee ACP volunteers undertaking a structured simulated event provided by a local acute hospital trust simulation team. A questionnaire (n=10) and a focus group (n=4) acted as the data gathering tools. RESULTS: Although simulation can be daunting for the participants, the overwhelming outcome was positive. Participants stated that they gained confidence and suggested that simulation offered a safe place to practise the challenging scenarios that occur in the clinical environment. Additionally, they emphasised that simulation provided a place to network and receive constructive feedback that was non-judgemental, and which helped them to develop clinical knowledge and appreciate their limitations. CONCLUSION: Simulation is a valuable addition to the education and development of ACPs. It should be considered for inclusion within the educational curriculum as a supplement to theoretical knowledge and to the structured clinical supervision provided within the clinical environment.
