Simulation can be a viable way to refine new medical guidelines for COVID-19 Simulation can be a viable way to quickly evaluate and refine new medical guidelines and educate hospital staff in new procedures, a recent study from UT Southwestern's Department of Pediatrics shows. The findings, published recently in the journal Pediatric Quality and Safety and originally shaped around new COVID-19-related pediatric resuscitation procedures at UTSW and Children's Health, could eventually be used to help implement other types of guidelines at medical centers nationwide. For decades, U.S. hospitals have used the same standard procedures for CPR and intubation. But when the COVID-19 pandemic began early last year, some details of these procedures needed to change, explains Blake E. Nichols, M.D., assistant professor of pediatrics at UTSW and a critical care physician at Children's Health.
