Introduction: Emergency Department (ED) resuscitation is a complex, high-stakes procedure where positive outcomes depend upon effective interactions between the healthcare team, the patient, and the environment. To this end, resuscitation teams work in spaces designed to optimize workflows and ensure that necessary treatments and skillsets are available when required. However, systematic failures in this environment cannot always be adequately anticipated, exposing patients to opportunities for harm. As part of a new interprofessional education initiative, this prospective, observational study sought to characterize latent threats to patient safety (LST’s) identified during the delivery of in-situ, simulated resuscitations in two Canadian, tertiary care, academic Emergency Departments. Methods: In-situ simulation sessions were delivered on a monthly basis in the EDs of each hospital campus, during which a variety of simulated resuscitation scenarios were run with distinct teams of ED healthcare professionals. A research assistant was present throughout each session and documented LST’s identified by simulation facilitators and participants during the case and debriefing. Data were entered into a master table and grouped thematically for analysis. Results: After a pilot run-in, 10 in-situ simulation sessions were delivered, involving 27 cases and reaching 180 ED healthcare professionals (25 attending MD, 37 resident MD, 59 RN, 24 RT). 83 latent safety threats were identified through these sessions (mean 3.1 LSTs per case) of which 52 were determined to be “actionable”. Corrective mechanisms have been initiated in 72% of these cases (e.g., new education campaigns and in-servicing, equipment provisioning, equipment checklists). Conclusion: In-situ simulation, beyond its role as a training tool for developing Non-Technical and Crisis Resource Management skills, can be effectively used to identify systematic deficits and knowledge gaps that could expose critically ill patients to harm. Effective quality improvement and continuing education programs are essential to translate these findings into more resilient patient care.

Introduction / Innovation Concept: During Emergency Department (ED) resuscitation of critically ill patients, effective teamwork and communication among various healthcare professionals is essential to ensure favorable patient outcomes and to minimize threats to patient safety. However, numerous individual and system factors create barriers to effective team functioning. Simulation center- based training has been used to improve Crisis Resource Management skills among physician and nursing trainees, but in-situ simulation is a relatively new concept in adult Emergency Medicine in North America. Methods: To enhance patient care and team effectiveness, an ED nursing and physician group was created to develop and implement a novel interprofessional in-situ simulation program in two Canadian, academic tertiary-care emergency departments. Departmental approval and financial support was obtained and sessions commenced in January 2015. Curriculum, Tool, or Material: Monthly high-fidelity simulation sessions are held in the ED resuscitation rooms at both campuses of our hospital. Each session is facilitated and debriefed by simulation-trained Emergency Medicine faculty and senior residents, a nurse educator and a research assistant. Technical support is provided by our simulation center staff. Participants are recruited from the physicians, residents, nurses, respiratory therapists and other support staff working in the ED. To minimize the impact on patient care, two additional nurses are scheduled to cover nursing assignments on “sim days”. Simulations are limited to fifteen minutes, followed by a twenty minute debriefing. Conclusion: We have successfully developed and implemented an interprofessional in-situ simulation program in our ED. Participant feedback has been overwhelmingly positive. Lack of financial support, reluctance of staff to participate, and overwhelmed resources are some of the challenges to running a program like this in a busy ED environment. However, there are clear benefits: empowering team members, culture change, identification of latent safety threats, and a perception of improved teamwork and communication.
