Simulation-based training lead to improvements in learning compared to no intervention but little is known of the effects on organizational improvements that are relevant to patient care. This study focused on the effects of training midwives in performing cervical ultrasound scans on continuity of care when managing pregnant women with symptoms of premature onset of labor. Our hypothesis is that simulation-based training can be used to decrease the number of shifts in primary responsible health care practitioner as midwives that are trained in cervical ultrasound scans may manage the patient encounter without engaging a second practitioner (i.e. an obstetrician).
