Effects of Brief Mental Skills Training on Emergency Medicine Residents' Stress Response During a Simulated Resuscitation: A Prospective Randomized Trial.

BACKGROUND: Acute stress impairs physician decision-making and clinical performance in resuscitations. Mental skills training, a component of the multistep, cognitive-behavioral technique of stress inoculation, modulates stress response in high-performance fields. OBJECTIVE: We assessed the effects of mental skills training on emergency medicine (EM) residents' stress response in simulated resuscitations as well as residents' perceptions of this intervention. METHODS: In this prospective, educational intervention trial, postgraduate year-2 EM residents in seven Chicago-area programs were randomly assigned to receive either stress inoculation training or not. One month prior to assessment, the intervention group received didactic training on the "Breathe, Talk, See, Focus" mental performance tool. A standardized, case-based simulation was used for assessment. We measured subjective stress response using the six-item short form of the Spielberger State-Trait Anxiety Inventory (STAI-6). Objective stress response was measured through heart rate (HR) and heart rate variability (HRV) monitoring. We measured subjects' perceptions of the training via survey. RESULTS: Of 92 eligible residents, 61 participated (25 intervention; 36 control). There were no significant differences in mean pre-/post-case STAI-6 scores (-1.7 intervention, 0.4 control; p = 0.38) or mean HRV (-3.8 milliseconds [ms] intervention, -3.8 ms control; p = 0.58). Post-assessment surveys indicated that residents found this training relevant and important. CONCLUSION: There was no difference in subjective or objective stress measures of EM resident stress response after a didactic, mental performance training session, although residents did value the training. More extensive or longitudinal stress inoculation curricula may provide benefit.

The Implementation of a National Multifaceted Emergency Medicine Resident Wellness Curriculum Is Not Associated With Changes in Burnout.

BACKGROUND: The Accreditation Council for Graduate Medical Education Common Program Requirements effective 2017 state that programs and sponsoring institutions have the same responsibility to address well-being as they do other aspects of resident competence. OBJECTIVES: The authors sought to determine if the implementation of a multifaceted wellness curriculum improved resident burnout as measured by the Maslach Burnout Inventory (MBI). METHODS: We performed a multicenter educational interventional trial at 10 emergency medicine (EM) residencies. In February 2017, we administered the MBI at all sites. A year-long wellness curriculum was then introduced at five intervention sites while five control sites agreed not to introduce new wellness initiatives during the study period. The MBI was readministered in August 2017 and February 2018. RESULTS: Of 523 potential respondents, 437 (83.5%) completed at least one MBI assessment. When burnout was assessed as a continuous variable, there was a statistically significant difference in the depersonalization component favoring the control sites at the baseline and final survey administrations. There was also a higher mean personal accomplishment score at the control sites at the second survey administration. However, when assessed as a dichotomous variable, there were no differences in global burnout between the groups at any survey administration and burnout scores did not change over time for either control or intervention sites. CONCLUSIONS: In this national study of EM residents, MBI scores remained stable over time and the introduction of a multifaceted wellness curriculum was not associated with changes in global burnout scores.

Comparing the Maslach Burnout Inventory to Other Well-Being Instruments in Emergency Medicine Residents.

BACKGROUND: The Maslach Burnout Inventory (MBI) is considered the "gold standard" for measuring burnout, encompassing 3 scales: emotional exhaustion, depersonalization, and personal accomplishment. Other well-being instruments have shown utility in various settings, and correlations between MBI and these instruments could provide evidence of relationships among key variables to guide well-being efforts. OBJECTIVE: We explored correlations between the MBI and other well-being instruments. METHODS: We fielded a multicenter survey of 9 emergency medicine (EM) residencies, administering the MBI and 4 published well-being instruments: a quality-of-life assessment, a work-life balance rating, an appraisal of career satisfaction, and the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire 2 question screen. Consistent with the Maslach definition, burnout was defined by high emotional exhaustion (> 26) and high depersonalization (> 12). RESULTS: Of 334 residents, 261 (78%) responded. Residents who reported lower quality of life had higher emotional exhaustion (ρ = -0.437, P < .0001), higher depersonalization (ρ = -0.18, P < .005), and lower personal accomplishment (ρ = 0.347, P < .001). Residents who reported a negative work-life balance had emotional exhaustion (P < .001) and depersonalization (P < .009). Positive career satisfaction was associated with lower emotional exhaustion (P < .0001), lower depersonalization (P < .005), and higher personal accomplishment (P < .05). A positive depression screen was associated with higher emotional exhaustion, higher depersonalization, and lower personal achievement (all P < .0001). CONCLUSIONS: Our multicenter study of EM residents demonstrated that assessments using the MBI correlate with other well-being instruments.

Development of an Emergency Medicine Wellness Curriculum.

Burnout, the triad of emotional exhaustion, depersonalization, and low personal accomplishment, begins early in medical education and the prevalence continues to increase over time among U.S. physicians. The Accreditation Council for Graduate Medical Education (ACGME) now requires that programs and sponsoring institutions have the same responsibility to address well-being as they do other aspects of resident competence. Yet, there are no studies published in the emergency medicine (EM) literature that discuss the development and institution of a formal wellness curriculum. The authors conducted a needs analysis among EM residents with the aim of creating a multifaceted 12-month wellness curriculum. The needs analysis determined that residents are not comfortable with their knowledge of wellness principles. In response, the authors developed a curriculum by integrating components of published non-EM wellness curricula and online academic wellness programs with commonly accepted domains of wellness. The curriculum was subsequently introduced at five EM residencies. This curriculum represents an example of successful multi-institution collaboration to meet an ACGME Common Program Requirement.

Antibiotic-induced serotonin syndrome.

Due to its broad spectrum of clinical presentations and to the large number of available serotonergic medications, serotonin syndrome (SS) remains an elusive diagnosis to many clinicians. SS results from the over-stimulation of serotonin receptors by a variety of mechanisms. New medications with the potential to cause SS are released regularly, and among them is the antibiotic linezolid. We present a case of SS in a 36-year-old woman that occurred after linezolid was added to a drug regimen that included lithium, venlafaxine, and imipramine.

Therapeutic hypothermia protocol in a community emergency department.

OBJECTIVES: Therapeutic hypothermia (TH) has been shown to improve survival and neurological outcome in patients resuscitated after out of hospital cardiac arrest (OHCA) from ventricular fibrillation/ventricular tachycardia (VF/VT). We evaluated the effects of using a TH protocol in a large community hospital emergency department (ED) for all patients with neurological impairment after resuscitated OHCA regardless of presenting rhythm. We hypothesized improved mortality and neurological outcomes without increased complication rates. METHODS: Our TH protocol entails cooling to 33°C for 24 hours with an endovascular catheter. We studied patients treated with this protocol from November 2006 to November 2008. All non-pregnant, unresponsive adult patients resuscitated from any initial rhythm were included. Exclusion criteria were initial hypotension or temperature less than 30°C, trauma, primary intracranial event, and coagulopathy. Control patients treated during the 12 months before the institution of our TH protocol met the same inclusion and exclusion criteria. We recorded survival to hospital discharge, neurological status at discharge, and rates of bleeding, sepsis, pneumonia, renal failure, and dysrhythmias in the first 72 hours of treatment. RESULTS: Mortality rates were 71.1% (95% CI, 56-86%) for 38 patients treated with TH and 72.3% (95% CI 59-86%) for 47 controls. In the TH group, 8% of patients (95% CI, 0-17%) had a good neurological outcome on discharge, compared to 0 (95% CI 0-8%) in the control group. In 17 patients with VF/VT treated with TH, mortality was 47% (95% CI 21-74%) and 18% (95% CI 0-38%) had good neurological outcome; in 9 control patients with VF/VT, mortality was 67% (95% CI 28-100%), and 0% (95% CI 0-30%) had good neurological outcome. The groups were well-matched with respect to sex and age. Complication rates were similar or favored the TH group. CONCLUSION: Instituting a TH protocol for OHCA patients with any presenting rhythm appears safe in a community hospital ED. A trend towards improved neurological outcome in TH patients was seen, but did not reach significance. Patients with VF appeared to derive more benefit from TH than patients with other rhythms.

Promoting diversity in emergency medicine: summary recommendations from the 2008 Council of Emergency Medicine Residency Directors (CORD) Academic Assembly Diversity Workgroup.

Although the U.S. population continues to become more diverse, ethnic and racial health care disparities persist. The benefits of a diverse medical workforce have been well described, but the percentage of emergency medicine (EM) residents from underrepresented groups (URGs) is small and has not significantly increased over the past 10 years. The Council of Emergency Medicine Resident Directors (CORD) requested that a panel of CORD members review the current state of ethnic and racial diversity in EM training programs. The objective of the discussion was to develop strategies to help EM residency programs examine and improve diversity in their respective institutions. Specific recommendations focus on URG applicant selection and recruitment strategies, cultural competence curriculum development, involvement of URG faculty, and the availability of institutional and national resources to improve and maintain diversity in EM training programs.

A prevalence study of methicillin-resistant Staphylococcus aureus colonization in emergency department health care workers.

STUDY OBJECTIVE: Few studies of the prevalence of nasal colonization of methicillin-resistant Staphylococcus aureus (MRSA) in emergency department (ED) health care workers have been conducted. To better understand the epidemiology of this pathogen, we seek to determine the MRSA nasal colonization rates in the ED health care workers in our hospital. METHODS: We conducted a prospective cohort study on a convenience sample of ED health care workers, including nurses, physicians, and technicians. Nasal swabs from subjects were analyzed with a polymerase chain reaction assay for the presence of MRSA. RESULTS: Of the 105 ED health care workers enrolled, a total of 16 (15%, 95% confidence interval 9.6% to 23%) were MRSA positive. No significant difference was observed in colonization rates between nurses, physicians, and technicians. CONCLUSION: Our ED health care workers demonstrated a high prevalence of nasal MRSA colonization compared with individuals in recent community surveillance and other studies involving ED staff.

A rapid quantitative turbimetric d-dimer assay has high sensitivity for detection of pulmonary embolism in the ED.

Many rapid d-dimer assays are commercially available with wide ranges of reported sensitivities, often based on small sample sizes. This has limited their intended use as rapid and inexpensive tests to evaluate pulmonary embolism in the low-risk patient. We sought to determine the sensitivity of the STA-Liatest D-Di d-dimer assay in our ED. We performed a retrospective analysis of 103 patients seen in our ED with the admitting diagnosis of known or suspected pulmonary embolism. These charts were assessed to establish if a d-dimer assay was performed within 24 hours. These charts were then reviewed to determine what diagnostic studies were performed and what final diagnosis was reached. Of the 103 charts identified, 55 had d-dimer assays performed within 24 hours. Of those, 38 were diagnosed with pulmonary embolism; none had negative d-dimer assays (<400 ng/mL). Using the exact method, the sensitivity of this assay was calculated to be 100% with a 95% confidence interval (CI) of 91.4% to 100%. Our results suggest that the STA-Liatest D-Di d-dimer assay could have an adequate sensitivity to be used to rule out pulmonary embolism in low-risk patients. Further prospective studies with larger sample sizes are required to validate this observation.
