to assess the evidence from multidisciplinary simulation team training in obstetrics that integrates human’s factors components on patient outcome.
It has been stated that simulation-based education has the potential to improve technical and nontechnical skills. Reports from enquiries into maternal and newborn adverse outcomes, highlight that the majority of incidents are due to a breakdown of communication and a lack of crisis resource management skills (CRM). It is therefore reasonable to think that a better training on teamwork based on simulation will ultimately improve obstetrics care. In order to explore further that idea, we conducted a literature review on patient outcome after a multidisciplinary simulation training in obstetrics.
Pubmed, Advances in health sciences education, BMC in medical education, BMC in pregnancy and Childbirth, BMJ open, BMJ Simulation and technology enhanced learning were searched from inception to May 2020 for full-text publications in English on interprofessional, multidisciplinary, obstetrics, simulation training, non-technical skills, CRM. Searches were limited to studies with a report on patient outcome after a multidisciplinary simulation program that included elements of CRM.
Out of the ten studies selected in our review, five were single site before and after prospective studies and five were cluster before and after randomized trials. All the single site studies reported a positive outcome in low and high resource countries. Three single site studies reported a reduction between 41 and 50 % of blood transfusion after simulation team training. Two single studies reported a reduction of maternal mortality by 34 % and a decrease in an adverse obstetrics index outcome from 0.052 to 0.048 with a p-value of 0.05. Cluster studies showed either no change or some improvement in patient outcomes such as a 37 % improvement on weighted obstetrics adverse outcome, a 17 % reduction in the incidence of PPH and a 47 % reduction in the incidence of retained placenta. Stillbirths rate was reduced by 34 % while newborn deaths was down by 62 %. There was also a 15 % reduction of maternal mortality in favor of the trained team after adjustment to the secular mortality trend. Neonatal death from 24 weeks during the first 24 h was also reduced by 83 % in the intervention site compare with an increase by 18 % in the control site.
There is evidence that simulation team training that includes CRM is associated with better patient outcome. In order to consolidate this finding, appropriate methodology should be used in future studies with the support of health authorities.
