Interprofessional Patient-Specific Simulation Preparation to Improve Management of Neonatal High-Acuity Low-Occurrence (HALO) Scenarios.

Fetal compressive intrapericardial teratoma is a rare and life-threatening condition, qualifying as a high-acuity low-occurrence (HALO) event. To prepare for delivery and immediate neonatal management, specialists from pediatric cardiology, cardiac surgery, maternal-fetal-medicine, neonatology, cardiac anesthesia, critical care, clinical perfusion, obstetrical nursing, and operating room nursing convened. An in situ operating room simulation was used to identify and introduce key team members, derive and practice the anticipated clinical management algorithm, position human and equipment resources strategically, and ensure that each specialist team was familiar with the environment and available equipment. As rehearsed in the simulation, the cesarean delivery of the patient and neonatal cardiac surgery was uncomplicated and yielded a favourable clinical outcome. A patient-specific HALO simulation preparation (PSHSP) can facilitate positive clinical outcomes and improve health care team confidence in HALO scenarios such as the birth of newborns anticipated to have cardiorespiratory instabilty.
