Defining Team Performance for Simulation‐based Training: Methodology, Metrics, and Opportunities for Emergency Medicine

Across health care, teamwork is a critical element for effective patient care. Yet, numerous well-intentioned training programs may fail to achieve the desired outcomes in team performance. Hope for the improvement of teamwork in health care is provided by the success of the aviation and military communities in utilizing simulation-based training (SBT) for training and evaluating teams. This consensus paper 1) proposes a scientifically based methodology for SBT design and evaluation, 2) reviews existing team performance metrics in health care along with recommendations, and 3) focuses on leadership as a target for SBT because it has a high likelihood to improve many team processes and ultimately performance. It is hoped that this discussion will assist those in emergency medicine (EM) and the larger health care field in the design and delivery of SBT for training and evaluating teamwork.

Incorporating abbreviated EEGs in the initial workup of patients who present to the emergency room with mental status changes of unknown etiology.

Patients frequently present to the emergency room (ER) with mental status changes without obvious cause. The EEG is underused in this population. The authors investigated whether an abbreviated EEG (AbEEG) can be incorporated in the early evaluation of these patients to provide useful information. A 5-minute AbEEG was performed using a preformed electrode placement system on 25 patients who presented to the ER with mental status changes of unknown cause. AbEEG findings were categorized as normal, showing diffuse abnormalities, focal abnormalities, electrographic seizures, or uninterpretable. Using retrospective chart review, the authors determined if the cause of mental status change was a diffuse encephalopathy or a nonneurologic event (DENNE), a focal brain abnormality, nonconvulsive status epilepticus (NCSE), psychogenic, or unknown, and if particular AbEEG findings were associated with specific causes of altered sensorium. The AbEEG identified NCSE in two patients who presented with new-onset seizures. The presence of diffuse slowing on the AbEEG was highly suggestive of mental status changes due to DENNE. AbEEGs can be successfully incorporated in the early evaluation of patients who present to the ER with mental status changes of unknown cause and provide useful information in this setting.

Clinical Policy: Critical Issues in the Evaluation and Management of Adult Patients Presenting to the Emergency Department With Seizures

This clinical policy from the American College of Emergency Physicians is the revision of a 2004 policy on critical issues in the evaluation and management of adult patients with seizures in the emergency department. A writing subcommittee reviewed the literature to derive evidence-based recommendations to help clinicians answer the following critical questions: (1) In patients with a first generalized convulsive seizure who have returned to their baseline clinical status, should antiepileptic therapy be initiated in the emergency department to prevent additional seizures? (2) In patients with a first unprovoked seizure who have returned to their baseline clinical status in the emergency department, should the patient be admitted to the hospital to prevent adverse events? (3) In patients with a known seizure disorder in which resuming their antiepileptic medication in the emergency department is deemed appropriate, does the route of administration impact recurrence of seizures? (4) In emergency department patients with generalized convulsive status epilepticus who continue to have seizures despite receiving optimal dosing of a benzodiazepine, which agent or agents should be administered next to terminate seizures? A literature search was performed, the evidence was graded, and recommendations were given based on the strength of the available data in the medical literature.

Simulation center accreditation and programmatic benchmarks: a review for emergency medicine.

Simulation-based education has grown significantly over the past 10 years. As a result, more professional organizations are developing or implementing accreditation processes to help define minimum standards and best practices in simulation-based training. However, the benefits and potential pitfalls of sponsoring and implementing such programs have yet to be fully evaluated across specialties. The board of directors of the Society for Academic Emergency Medicine (SAEM) requested an evaluation of the potential to create an emergency medicine (EM)-based Simulation Consultation and Accreditation Service. In response to this request, the Simulation Accreditation and Consultation Work Group, a subgroup of the Committee on Technology in Medical Education (now Simulation Academy), was created. The work group was charged with: 1) reviewing current benchmarks and standards set by existing simulation accreditation programs; 2) analyzing current EM simulation program structures, including leadership, administrative, and financial components; and 3) proposing a potential model for EM-based simulation accreditation. This article outlines currently existing and proposed accreditation models and identifies components that support best practices. It then goes on to describe three general programmatic models to better understand how simulation training can be operationalized in EM. Finally, the work group uses this collective information to propose how an accreditation process, in concert with the SAEM Simulation Consultation Service, can enhance and advance EM simulation training.

Proactive rounding by the rapid response team reduces inpatient cardiac arrests

OBJECTIVE Rapid response teams (RRTs) are frequently employed to respond to deteriorating inpatients. Proactive rounding (PR) consists of the RRT nurse rounding through the inpatient wards identifying high risk patients and intervening preemptively. At our institution, PR began in July of 2007. Our objective was to determine the effect of PR by the RRT at our institution on non-ICU cardiac arrests, code deaths, RRT interventions, and transfers to a higher level of care. Also, to report ICU transfer survival and survival to discharge rates after the start of PR. DESIGN Retrospective review of a prospectively collected database. SETTING A tertiary, academic, level 1 trauma center with 696 beds and a rapid response system. PATIENTS 1253 Non-ICU cardiac arrests from 2005 through June of 2012. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The total study period included 223,267 inpatient admissions (70,129 pre-PR and 153,138 post-PR) and 1,250,814 patient days (391,088 pre-PR and 859,726 post-PR). The quarterly code rate before PR was 66 and the code rate after the institution of PR was 30 (difference=36.8, 95% CI 25.6-48.0, p<.001). Quarterly code deaths decreased from 29 to 7 (difference=21.95, 95% CI 16.3-27.6, p<.001). This decrease in floor codes and code deaths was still present after adjusting for inpatient admission and inpatient days. Average quarterly RRT interventions increased from 141 in the pre-PR period to 690 in the post-PR period (difference=549, 95% CI 360-738, p<.001). Average quarterly transfers to HLC went up from 38 pre-PR to 164 post-PR (difference=126, 95% CI 79-172, p<.001). CONCLUSIONS The institution of proactive rounding at a tertiary care, academic, level 1 trauma center results in reduced floor codes and code deaths as well as increased RRT interventions and transfers to a higher level of care.

Clinical Policy: Critical Issues in the Evaluation of Adult Patients With Suspected Transient Ischemic Attack in the Emergency Department

This clinical policy from the American College of Emergency Physicians addresses key issues for adults presenting to the emergency department with suspected transient ischemic attack. A writing subcommittee conducted a systematic review of the literature to derive evidence-based recommendations to answer the following clinical questions: (1) In adult patients with suspected transient ischemic attack, are there clinical decision rules that can identify patients at very low short-term risk for stroke who can be safely discharged from the emergency department? (2) In adult patients with suspected transient ischemic attack, what imaging can be safely delayed from the initial emergency department workup? (3) In adult patients with suspected transient ischemic attack, is carotid ultrasonography as accurate as neck computed tomography angiography or magnetic resonance angiography in identifying severe carotid stenosis? (4) In adult patients with suspected transient ischemic attack, can a rapid emergency department-based diagnostic protocol safely identify patients at short-term risk for stroke? Evidence was graded and recommendations were made based on the strength of the available data.

Impact of an abbreviated cardiac enzyme protocol to aid rapid discharge of patients with cocaine-associated chest pain in the clinical decision unit.

Introduction In 2007 there were 64,000 visits to the emergency department (ED) for possible myocardial infarction (MI) related to cocaine use. Prior studies have demonstrated that low- to intermediate-risk patients with cocaine-associated chest pain can be safely discharged after 9–12 hours of observation. The goal of this study was to determine the safety of an 8-hour protocol for ruling out MI in patients who presented with cocaine-associated chest pain. Methods We conducted a retrospective review of patients treated with an 8-hour cocaine chest pain protocol between May 1, 2011 and November 30, 2012 who were sent to the clinical decision unit (CDU) for observation. The protocol included serial cardiac biomarker testing with Troponin-T, CK-MB (including delta CK-MB), and total CK at 0, 2, 4, and 8 hours after presentation with cardiac monitoring for the observation period. Patients were followed up for adverse cardiac events or death within 30 days of discharge. Results There were 111 admissions to the CDU for cocaine chest pain during the study period. One patient had a delta CK-MB of 1.6 ng/ml, but had negative Troponin-T at all time points. No patient had a positive Troponin-T or CK-MB at 0, 2, 4 or 8 hours, and there were no MIs or deaths within 30 days of discharge. Most patients were discharged home (103) and there were 8 inpatient admissions from the CDU. Of the admitted patients, 2 had additional stress tests that were negative, 1 had additional cardiac biomarkers that were negative, and all 8 patients were discharged home. The estimated risk of missing MI using our protocol is, with 99% confidence, less than 5.1% and with 95% confidence, less than 3.6% (99% CI, 0–5.1%; 95% CI, 0–3.6%). Conclusion Application of an abbreviated cardiac enzyme protocol resulted in the safe and rapid discharge of patients presenting to the ED with cocaine-associated chest pain.

Naloxone Triggering the RRT: A Human Antidote?

Objectives At our institution, we observed an increase in opioid-related adverse events after instituting a new pain treatment protocol. To prevent this, we programmed the Omnicell drug dispensing system to page the RRT whenever naloxone was withdrawn on the general wards. Methods Retrospective review of a prospectively collected database with a before and after design. Results When comparing the two 12-month periods, there was a decrease in monthly opioid-related cardiac arrests from 0.75 to 0.25 per month (difference = 0.5; 95% CI, 0.04–0.96, P = 0.03) and a nearly significant decrease in code deaths from 0.25 to 0 per month (difference = −0.25; 95% CI, −0.02–0.52, P = 0.07) without a significant decrease in pain satisfaction scores (difference = −2.3; 95% CI, −4.4 to 9.0, P = 0.48) over the study period. There were also decreased RRT interventions from 7.3 to 5.6 per month (difference = −1.7; 95% CI, −0.31 to −3.03, P = 0.02) and decreased inpatient transfers from 2.9 to 1.8 transfers per month (difference = −1.2; 95% CI, −0.38 to −1.96, P = 0.005). When adjusting for inpatient admissions and inpatient days, there was a decrease in opioid-related cardiac arrests from 2.9 to 0.1 per 10,000 admissions (difference = −2.0; 95% CI, −0.2 to −3.8, P = 0.03) and a decrease in cardiac arrests from 0.5 to 0.2 per 10,000 patients (difference = −0.34; 95% CI, −.02 to −0.65, P = 0.04). Conclusion Naloxone-triggered activation of the RRT resulted in reduced opioid-related inpatient cardiac arrests without adversely affecting pain satisfaction scores.

End-tidal carbon dioxide and occult injury in trauma patients ☆: ETCO2 does not rule out severe injury

OBJECTIVE To determine if early measurement of end-tidal carbon dioxide (ETCO2) in nonintubated patients triaged to a level 1 trauma center has utility in ruling out severe injury. METHODS We performed a prospective cohort study of adult patients triaged to our urban, academic, level 1 trauma center. Included patients had ETCO2 measured within 30 minutes of arrival. Chart review was performed on enrolled patients to identify severe injury defined by: admission to an intensive care unit, need for an invasive procedure, blood product transfusion, acute blood loss anemia, and acute clinically significant finding on computed tomographic scan. RESULTS Of 170 patients enrolled, 115 met the outcome of no severe injury. Mean ETCO2 for patients without and with severe injury was 33.1 mm Hg (SD, 5.8) and 30.3 mm Hg (SD, 6.7), respectively. This difference reached statistical significance (P=.05), but did not demonstrate added clinical utility when combined with Glasgow Coma Scale, systolic blood pressure, and age in predicting the primary outcome (area under curve, 0.70 with ETCO2 vs area under curve, 0.68 without ETCO2, P=.5). Patients with ETCO2 ≤30 mm Hg were found to be older, more likely to require intensive care unit admission or emergency operative intervention, develop acute blood loss anemia, and have an acute finding on computed tomography than patients with a higher ETCO2. CONCLUSION End-tidal carbon dioxide cannot be used to rule out severe injury in patients meeting criteria for trauma center care. The ETCO2 ≤30 mm Hg may be associated with increased risk of traumatic severe injury.
