Validation of a simulation-based resuscitation curriculum for maternal cardiac arrest.
The purpose of this study was to evaluate the knowledge, skills, and self-efficacy of health care participants completing a simulation-based blended learning training curriculum on managing maternal medical emergencies and maternal cardiac arrest. The study included a formative assessment of the Obstetric Life Support curriculum. The training consisted of self-guided pre-course work and an instructor-led simulation course using a customized low-fidelity simulator. Eighty-five participants consented to participation in the training (out of 88 invited); 77 participants completed the training over eight sessions. The study found that at baseline, less than 50% of participants were able to achieve a passing score on the cognitive assessment. After the course, mean cognitive assessment scores improved by 13 points, from 69.4% at baseline to 82.4% after the course. The researchers observed significant improvements in participant self-efficacy, and 92.6% of participants agreed or strongly agreed that the course met its educational objectives.

A novel patient-specific computational fluid dynamics study of the activation of primary collateral pathways in the Circle of Willis during vasospasm.
This study presented a novel technique to create patient-specific computational fluid dynamics simulations of the Circle of Willis (a redundant network of blood vessels that perfuses the brain) before and during vasospasm. Computed tomographic angiography scans are segmented to model the vasculature, and transcranial Doppler ultrasound measurements of blood flow velocity are applied as boundary conditions. The authors stated that this analysis can be applied in future to a cohort of patients to investigate the relationship between the locations and severities of vasospasm, anatomical variability in individuals’ Circle of Willis, and the activation of collateral pathways.

Staying current: developing just-in-time evidence-ased learning objectives for a maternal cardiac arrest simulation curriculum.
The authors’ objective was to review the latest evidence on resuscitation care for maternal cardiac arrest (MCA) and to gain expert consensus on best practices to inform an evidence-based curriculum. A multidisciplinary panel of stakeholders in MCA developed an evidence-based simulation training, Obstetric Life Support™ (OBLS). The researchers found that a novel three-step process including reaffirmation of evidence process, systematic review, and a modified Research and Development technique resulted in unanimous consensus from experts in MCA resuscitation on existing and new just-in-time best practices to inform the learning objectives for an evidence-based curriculum.

System-based interprofessional simulation-based training program increases awareness and use of rapid response teams.
The objective of this study was to develop and implement an interprofessional simulation-based training program for rapid response and cardiac arrest emergencies with emphasis on early recognition and effective communication. The researchers concluded that their study demonstrated that rapid response team underuse due to system barriers may be overcome by this type of program targeting specific needs of the institution.
