Background: Emergency physicians have the highest rates of burnout among all specialties. Existing burnout tools include the Copenhagen Burnout Inventory (CBI) and single-item measures from the Maslach Burnout Inventory (MBI). While both were designed to measure burnout, how they conceptualize this phenomenon differs and their agreement is unclear. Given the close conceptual relationship between emotional regulation strategies such as distancing and distraction with the MBI subscale of depersonalization, we examined agreement between the two inventories and association with emotional regulation strategies as a lens to explore the conceptualization of burnout.

Methods: We conducted a cross-sectional survey of adult and pediatric emergency physicians and trainees in Canada. Survey questions were pretested using written feedback and cognitive interviews. "Frequent use" of an emotional regulation strategy was "most" or "all" shifts (≥4 on 5-point Likert scale). Burnout was defined as mean ≥50/100 on the CBI and scoring ≥5 (out of 7) on at least one of the single-item measures from the MBI. Associations with burnout were examined using multivariable logistic regression.

Results: Of 147 respondents, 44.2% were positive for burnout on the CBI and 44.9% on the single-item measures from the MBI. Disagreement was 21.1% overall, ranging from 12.5% for older (≥55 years) physicians to 30.2% for younger (<35 years) physicians. Use of distraction and use of distancing were strongly associated with burnout on the single-item measures (adjusted odds ratio [aOR] 14.4, 95% confidence interval [CI] 3.4-60.8]) and CBI (aOR 10.1, 95% CI 2.5-39.8, respectively.

Conclusions: Despite near-equal rates of burnout, agreement between the CBI and single-item measures from the MBI varies and was lower for younger emergency physicians/trainees. While emotional regulation strategies were felt to be important in supporting a career in emergency medicine, they were strongly associated with burnout. Future research is needed to better understand this phenomenon and which tools to use to measure burnout.

Background: The use of a computed tomography pulmonary angiogram to diagnose pulmonary embolism (PE) has increased, leading not only to higher PE diagnoses but also to overdiagnosis and unnecessary radiation exposure, even in young patients despite a lower PE incidence. The aim of this study was to assess the failure rate of the pulmonary embolism rule-out criteria 35 (PERC-35) rule developed to reduce unnecessary testing in individuals aged ≤35 years among patients included in the Registro Informatizado de la Enfermedad TromboEmbolica Venosa (RIETE) Registry.

Methods: This retrospective cohort study used data from the RIETE Registry, an ongoing, international prospective registry of patients with objectively confirmed venous thromboembolism. The primary outcome was the missed PE rate using PERC-35 criteria. Secondary outcomes included the comparison of demographic and clinical characteristics, PE localization, treatment strategies, and outcomes between PERC-negative (PERC-35N) versus PERC-positive (PERC-35P) patients.

Results: Of 58,918 adult patients with acute PE, the PERC-35 rule demonstrated a low missed PE rate of 0.35% (n = 204), with an upper 95% confidence interval [CI] of 0.40%. The missed rate was 7.0% (95% CI 6.0%-7.9%) in the 18- to 35-year subgroup. Compared to PERC-35P patients, PERC-35N patients were younger (mean age 28.4 years), with a lower body mass index, and included a higher proportion of pregnant/postpartum women. PERC-35N patients had a significantly lower rate of chronic diseases and presented less frequently with dyspnea or syncope but more often with chest pain. They showed lower rates of positive D-dimer and troponin levels. PERC-35N patients experienced fewer major bleeding episodes, similar recurrence rates of PE/deep vein thrombosis, and no deaths during anticoagulation.

Conclusions: The PERC-35 rule demonstrated a low failure rate to exclude PE in patients aged 18-35 years and could reduce imaging and radiation exposure in young patients with a low PE pretest probability if confirmed prospectively.
