RESUMO
BACKGROUND: The prevalence of physician burnout increased notably during the COVID-19 pandemic, but whether measures of burnout differed based on physician specialty is unknown. The authors sought to determine the prevalence of burnout, worklife conflict, and intention to quit among physicians from different specialties. METHODS: This is a cross-sectional online survey of physicians working at 2 urban hospitals in Vancouver, Canada, from August to October 2021. Responses were categorized by specialty (including surgical and nonsurgical), and data about whether physicians provided frontline patient care during COVID-19 were also included. Physician burnout was measured using the Maslach Burnout Inventory. Responses were categorized by specialty (including surgical and nonsurgical), and data about whether physicians provided frontline patient care during COVID-19 were also included. RESULTS: The survey response rate was 42% (209/498). The overall prevalence of burnout was 69%. Burnout was not significantly different by specialty or between frontline COVID-19 specialties compared with other specialties. Physicians in surgical specialties were more likely to report work-life conflict than those in nonsurgical specialties (p = 0.012). Differences in intention to quit among specialties were not statistically significant. CONCLUSION: During the COVID-19 pandemic, physician burnout was high across physicians, without significant differences between specialties, highlighting the need to support all physicians.
RESUMO
We investigated the relationship between air pollution and incidence of cardiac arrhythmia in a study of patients with implantable cardioverter defibrillators (ICDs). Thirty-four patients (ages 15-85 yr, 80% male) with ICDs residing in the Vancouver, Canada, area were included in the analyses, representing all patients attending the 2 ICD clinics in the study region who had recorded at least 1 ICD discharge during the 14 February to 31 December 2000 study period. Air pollutant (PM(2.5), PM(10), SO(4)(2-), elemental carbon [EC], organic carbon [OC], O(3), SO(2), NO(2), and CO) concentrations on days for which ICD discharges were observed ("case days") were compared to concentrations on control days in case-crossover analyses. Control days were selected symmetrically, 7 days before and after each case day. ICD discharges occurring within 72 h of 1 another were grouped and considered as 1 discharge event. Temperature, relative humidity, barometric pressure, rainfall, and wind speed were included simultaneously as covariates. Sensitivity analyses examined the effect of grouping ICD discharges, of including meteorological variables, and of excluding discharges that were considered inappropriate by a cardiologist. As in previous studies, mean concentrations and interquartile ranges of air pollutants in Vancouver were low (e.g., PM(2.5) mean = 8.2 microg/m(3)). Although in general there were no statistically significant results, there were trends that might indicate associations between pollutants and ICD discharges. Odds ratios (OR) were consistently higher in summer than in winter (e.g., lag 0 per interquartile range increase in EC: 1.09 [0.86-1.37] vs. 0.61 [0.31-1.18]) and, in general, the highest ORs were observed for same-day effects. The one major exception was the observation of high ORs for ozone in winter (e.g., lag 1: 2.27 [0.67-7.66]). While an OR of 1.55 (0.51-4.70) was observed in summer at lag 0 for PM(10), no indications of positive associations were observed for PM(2.5) or SO(4)(2-). For indicators of local combustion-source pollution, EC, OC, CO, and SO(2), ORs were elevated at all lags (0-3 days) in summer. In summary, this study provides little evidence that specific components of PM affect risk of cardiac arrhythmias, although power limited the ability of the study to detect small effects.
