This chapter describes the types and the role of simulation training in clinical management of a patient. The role of simulation training is to introduce and explore the concept of human factors and to allow development of technical and non-technical skills. It is aimed at increasing exposure to rare events which can reduce poor outcomes and ultimately improve maternal care and patient experience. The background of personnel delivering simulation training can be extremely varied and represents the skill mix required specifically for the complexity of manikin used or whether the training involves a full immersion simulation laboratory or a clinical environment, uses video debrief or team evaluation, for example. Patient actors, anatomical models and complex manikins are useful in training. The Simulation and Fire-drill Evaluation (SaFE) Study demonstrated that multiprofessional obstetric emergency training improves knowledge of both midwives and doctors of all experience levels.
