Simulation to assess the safety of new healthcare teams and new facilities.

INTRODUCTION: : Our institution recently opened a satellite hospital including a pediatric emergency department. The staffing model at this facility does not include residents or subspecialists, a substantial difference from our main hospital. Our previous work and published reports demonstrate that simulation can identify latent safety threats (LSTs) in both new and established settings. Using simulation, our objective was to define optimal staff roles, refine scope of practice, and identify LSTs before facility opening. METHODS: : Laboratory simulations were used to define roles and scope of practice. After each simulation, teams were debriefed using video recordings. The National Aeronautics and Space Administration-Task Load Index was completed by each participant to measure perceived workload. Simulations were scored for team behaviors by video reviewers using the Mayo High Performance Team Scale. Subsequent in situ simulations focused on identifying LSTs and monitoring for unintended consequences from changes made. RESULTS: : Twenty-four simulations were performed over 3 months before the hospital opening. Laboratory debriefing identified the need to modify provider responsibilities. National Aeronautics and Space Administration-Task Load Index scores and debriefings demonstrated that the medication nurse had the greatest workload during resuscitations. Modifying medication delivery was deemed critical. Lower Mayo High Performance Team Scale scores, implying less teamwork, were noted during in situ simulations. In situ sessions identified 37 LSTs involving equipment, personnel, and resources. CONCLUSIONS: : Simulation can help determine provider workload, refine team responsibilities, and identify LSTs. This pilot project provides a template for evaluation of new teams and clinical settings before patient exposure.

Feasibility of neuroprotective agent administration by prehospital personnel in an urban setting.

BACKGROUND AND PURPOSE: Studies have demonstrated the importance of early stroke treatment. If a neuroprotective agent (NA) clinical trial is successful, the greatest benefit might be attained with early prehospital administration. This study determined the potential reduction in time to treatment of stroke patients when NAs were administered in the prehospital setting. METHODS: Twenty-three urban emergency medical services (EMS) agencies participated in this study. Prehospital personnel completed a stroke assessment checklist on any potential stroke victim. The checklist collected clinical inclusion/exclusion criteria for NA administration and event/decision times. Patients meeting the hypothetical clinical inclusion criteria were enrolled into this study. Time data included scene arrival/departure, emergency department (ED) arrival, and estimated time of theoretical NA administration. The reduction in time to stroke treatment was calculated as the difference between the time of ED arrival and the reported time of NA administration. The t test and simple linear regression were used to probe for differences in treatment time reduction between selected subgroups. EMS personnel's ability to obtain informed consent for theoretical NA administration was calculated. RESULTS: Two hundred twenty-two patients were enrolled in this study; of these, 75 were deemed eligible for hypothetical NA administration and had complete time data. On average, EMS personnel documented the theoretical time of NA administration at 12.04+/-2.07 minutes before arrival at the ED (17.06+/-1.74 minutes when the NA was given on scene [n=43]; 6.65+/-1.14 minutes when the NA was given en route [n=32]). CONCLUSIONS: Prehospital NA administration can potentially significantly reduce the time to first intervention in stroke patients.

Teaching ACLS stroke objectives to prehospital providers: a case-based approach.

OBJECTIVES: To determine whether a case-based educational module would increase prehospital care providers' short-term and long-term knowledge about stroke and to compare the educational impact when the module was moderated by a physician versus an advanced cardiac life support (ACLS) instructor. METHODS: A stroke module consisting of two case-based scenarios was administered to emergency medical services (EMS) personnel by either an ACLS instructor or a physician. Identical 25-question tests (based on 1997 ACLS prehospital stroke objectives) were administered before and after the module. Descriptive statistics were calculated by groups, and Wilcoxon tests were used to assess the significance of improvement in scores based on the paired data. RESULTS: Two hundred six EMS personnel [112 (54%) emergency medical technician (EMT)-P, 91 (44%) EMT-B/EMT-I, and three (2%) other training levels] participated in the module, of whom 74 [30 (41%) EMT-P, 42 (57%) EMT-B/EMT-I, and two (2%) other training levels] participated in follow-up testing between six and seven months. Overall, there was a 32% improvement in test scores immediately after completion of the module (p < 0.001) and an 18% improvement at six months (p < 0.001). No significant difference in pretest scores existed between the physician-led and ACLS instructor-led groups (mean EMT-P pretest scores 69% versus 70% and EMT-B/EMT-I scores 55% versus 54%, respectively). There was no significant difference in short-term (p = 0.36) or long-term (p = 0.074) score improvements between the two groups. CONCLUSION: This case-based approach to EMS stroke education is effective and can achieve equal benefit when administered by a physician or an ACLS instructor.
