Improving maternal and perinatal care is a global priority. Practical simulation training for maternity care might prevent many of these deaths. There have been numerous evaluation studies published on the effectiveness of simulation training for obstetric emergencies, with increasing evidence that it is associated with improvement in clinical outcomes. Evidence has begun to move from subjective assessment of participants’ experiences towards objective assessment of clinical outcomes. However, the results are not entirely consistent and, at present, all of the evidence associating training with improvements in clinical

outcomes relates to neonatal outcomes. This review summarises recent progress in the evaluation of the effectiveness of simulation training for maternity care in both high- and low-resource settings, and presents a vision for ensuring that practical simulation training for maternity care can become an effective tool to reduce global maternal and perinatal morbidity and mortality. Keywords Clinical outcomes, mannequins, medical simulation,

obstetric emergencies.

Introduction Improving maternal and perinatal care is a global priority. The World Health Organization (WHO)1 has estimated that 1000 women die every day from preventable complications of pregnancy and childbirth. Worldwide, there are approximately four million neonatal deaths each year and a similar number of stillbirths.2 Practical simulation training for maternity care might prevent many of these deaths. Simulation training in obstetrics is not new. In 1748, Madame du Coudray, the King of France’s midwife, developed a life-size mannequin from leather and bone to teach the management of childbirth.3 She trained local doctors who, in turn, trained local women. In this way, du Coudray disseminated practical training, enabling hundreds of women in France to experience safer childbirth.3 Over 250 years later, there appeared to have been little progress; a systematic review of obstetric emergencies training published in 2003 concluded that few methods of training had been evaluated, and there was minimal evidence of their effectiveness.4 This review summarises the 8 years of progress since 2003 and presents a vision for ensuring that practical simulation training for maternity care can become an effective

tool to reduce global maternal and perinatal morbidity and mortality.

Evidence for effectiveness Numerous studies have evaluated the effectiveness of practical simulation training for obstetric emergencies, with increasing evidence that practical training is associated with improvements in clinical outcomes.5–9 The results are not entirely consistent, however. Emerging evidence for training for individual emergencies is presented below.

Eclampsia One of the first published descriptions of obstetric simulation was an eclampsia drill.10 The simulation of eclampsia enabled departmental staff to develop and trial an eclampsia box containing the equipment, drugs and guidelines required to manage this rare emergency. A randomised controlled trial comparing the effectiveness of multiprofessional training for eclampsia in local hospitals with training in a regional simulation centre showed marked improvement in all aspects of care after training.11 Training at local sites involved patient-actors, whereas a high-fidelity, full-body simulator was used at the simulation centre; 140

midwives and obstetricians were randomly allocated to local or simulation centre training. Following training, there were significant improvements in the completion of basic tasks (87%, 100%) and in the administration of magnesium sulphate (61%, 92%) in simulated eclampsia. The time taken to commence the administration of magnesium was, on average, nearly 2 minutes quicker following training. There were equal improvements in both settings; it was the training itself, rather than the location or the simulation equipment used, that appeared to be the key to success.11

Shoulder dystocia Shoulder dystocia is an unpredictable and therefore unpreventable emergency. A large, multisite, randomised controlled trial demonstrated that the management of shoulder dystocia before training was often poor, with only 43% of staff able to successfully manage severe shoulder dystocia.12 Following a 40-minute practical training session undertaken in multiprofessional teams, there was a significant improvement in the proportion of participants who successfully achieved simulated delivery (43% pre- and 83% post-training). This improvement was largely sustained at 6 months (84%) and 12 months (85%) after training. Training on a high-fidelity mannequin (which included force-perception teaching) offered additional benefit when compared with training on standard equipment; after training, there was a higher successful delivery rate (72%, 94%) and, on average, the deliveries were completed more quickly with a lower total force applied. Deering et al.13 and Goffman et al.14separately demonstrated improved performance of advanced shoulder dystocia manoeuvres following simulation training. Deering et al.13 found that obstetric trainees who had undergone simulation training scored better for the timeliness of both completion of manoeuvres and delivery compared with those who had received conventional training. Of greater importance is the effect of shoulder dystocia training on clinical outcomes. A retrospective review over an 8-year period compared birth outcomes for shoulder dystocia before and after the introduction of a local training programme in one UK hospital using a prototype PROMPT Birthing Trainer (Limbs and Things Ltd, Bristol, UK).7 Following the introduction of training, there was a significant increase in the use of appropriate management manoeuvres, with at least one appropriate manoeuvre used in 90% of cases after training, compared with
