Suicidal ideation, perception of personal safety, and career regret among emergency medicine residents during the COVID-19 pandemic.

Objectives: The COVID-19 pandemic was disruptive for trainees and may have affected career decisions for some learners. This study examined the impact of the pandemic on emergency medicine (EM) resident perceptions of their mental health, perceptions of personal safety, and career choice regret. Methods: This was a cross-sectional survey study administered following the 2021 American Board of Emergency Medicine In-Training Examination (ITE). Survey measures included suicidal ideation (SI), COVID concerns in terms of infection prevention and control (IPC) training, COVID risk to self and/or COVID risk to family, and COVID-related career regret. COVID concerns were compared by gender and race/ethnicity using Pearson's chi-square tests. Multivariable logistic regression models were used to test the association between SI and COVID concerns, resident characteristics, and program characteristics. Results: A total of 6980 out of 8491 EM residents (82.2%) from 244 programs completed the survey. Only 1.1% of participants reported insufficient training in COVID IPC practices. Participants were concerned about COVID risk to themselves (40.3%) and to their families (63.3%) due to their job roles. These concerns were more common among women or nonbinary (vs. men); all other races/ethnicities (vs. non-Hispanic Whites); senior residents (vs. PGY-1, PGY-2 residents); and residents who were married or in relationships (vs. single or divorced). A total of 6.1% of participants reported that COVID made them reconsider choosing EM as their career. Career regret in this cohort was higher than that in the proportion (3.2%) expressing career regret in the 2020 ITE (p < 0.001). Career regret was more common among women or nonbinary (vs. men); all other races/ethnicities (vs. non-Hispanic Whites); and senior residents (vs. PGY-1, PGY-2 residents). The overall SI rate was 2.6%, which did not differ from that of the 2020 sample of EM residents (2.5%, p = 0.88). Conclusions: Many EM residents reported concerns about COVID risks to themselves and their families. Although the rate of SI remained unchanged, more EM residents reported career regret during the COVID pandemic.

"Cold feet": A qualitative study of medical students who seriously considered emergency medicine but chose another specialty.

Introduction: Emergency medicine (EM) has historically been among the most competitive specialties in the United States. However, in 2022 and 2023, 219 of 2921 and 554 of 3010 respective National Resident Matching Program positions were initially unfilled. Medical students' selection of a medical specialty is a complex process. To better understand recent trends in the EM residency match, this qualitative study explored through one-on-one interviews the rationale of senior medical students who seriously considered EM but ultimately pursued another specialty. Methods: A convenience sample of senior medical students from across the United States was recruited via multiple mechanisms after the 2023 match. Participant characteristics were collected via an online survey. Qualitative data were generated through a series of one-on-one semistructured interviews and thematic analysis of the data was performed using a constant comparative approach. Results: Sixteen senior medical students from 12 different institutions participated in the study. Thematic saturation was reached after 12 interviews but data from all 16 interviews were included for qualitative analyses. Five major themes emerged as important in students' consideration but ultimate rejection of EM as a career: (1) innate features of EM attracted or dissuaded students, (2) widespread awareness of a recent workforce report, (3) burnout in EM, (4) their perception of EM's standing in the health care landscape, and (5) early EM experience and exposure. Conclusions: This qualitative study identified five major themes in the career decisions of senior medical students who seriously considered EM but chose another specialty. These findings may help inform the perceptions of students and guide future EM recruitment efforts.

Risk Stratification of COVID-19 Patients Using Ambulatory Oxygen Saturation in the Emergency Department.

INTRODUCTION: It is difficult to determine illness severity for coronavirus disease 2019 (COVID-19) patients, especially among stable-appearing emergency department (ED) patients. We evaluated patient outcomes among ED patients with a documented ambulatory oxygen saturation measurement. METHODS: This was a retrospective chart review of ED patients seen at New York University Langone Health during the peak of the COVID-19 pandemic in New York City. We identified ED patients who had a documented ambulatory oxygen saturation. We studied the outcomes of high oxygen requirement (defined as >4 liters per minute) and mechanical ventilation among admitted patients and bounceback admissions among discharged patients. We also performed logistic regression and compared the performance of different ambulatory oxygen saturation cutoffs in predicting these outcomes. RESULTS: Between March 15-April 14, 2020, 6194 patients presented with fever, cough, or shortness of breath at our EDs. Of these patients, 648 (11%) had a documented ambulatory oxygen saturation, of which 165 (24%) were admitted. Notably, admitted and discharged patients had similar initial vital signs. However, the average ambulatory oxygen saturation among admitted patients was significantly lower at 89% compared to 96% among discharged patients (p<0.01). Among admitted patients with an ambulatory oxygen saturation, 30% had high oxygen requirements and 8% required mechanical ventilation. These rates were predicted by low ambulatory oxygen saturation (p<0.01). Among discharged patients, 50 (10%) had a subsequent ED visit resulting in admission. Although bounceback admissions were predicted by ambulatory oxygen saturation at the first ED visit (p<0.01), our analysis of cutoffs suggested that this association may not be clinically useful. CONCLUSION: Measuring ambulatory oxygen saturation can help ED clinicians identify patients who may require high levels of oxygen or mechanical ventilation during admission. However, it is less useful for identifying which patients may deteriorate clinically in the days after ED discharge and require subsequent hospitalization.

Psychiatric Outcomes of Patients With Severe Agitation Following Administration of Prehospital Ketamine.

BACKGROUND: Ketamine is an emerging drug used in the management of undifferentiated, severe agitation in the prehospital setting. However, prior work has indicated that ketamine may exacerbate psychotic symptoms in patients with schizophrenia. The objective of this study was to describe psychiatric outcomes in patients who receive prehospital ketamine for severe agitation. METHODS: This is a retrospective cohort study, conducted at two tertiary academic medical centers, utilizing chart review of patients requiring prehospital sedation for severe agitation from January 1, 2014, to June 30, 2016. Patients received either intramuscular (IM) versus intravenous (IV) ketamine or IM versus IV benzodiazepine. The primary outcome was psychiatric inpatient admission with secondary outcomes including ED psychiatric evaluation and nonpsychiatric inpatient admission. Generalized estimating equations and Fisher's exact tests were used to compare cohorts. RESULTS: During the study period, 141 patient encounters met inclusion with 59 (42%) receiving prehospital ketamine. There were no statistically significant differences between the ketamine and benzodiazepine cohorts for psychiatric inpatient admission (6.8% vs. 2.4%, difference = 4.3%, 95% CI = -2% to 12%, p = 0.23) or ED psychiatric evaluation (8.6% vs. 15%, difference = -6.8%, 95% CI = -18% to 5%, p = 0.23). Patients with schizophrenia who received ketamine did not require psychiatric inpatient admission (17% vs. 10%, difference = 6.7%, 95% CI = -46% to 79%, p = 0.63) or ED psychiatric evaluation (17% vs. 50%, difference = -33%, 95% CI = -100% to 33%, p = 0.55) significantly more than those who received benzodiazepines, although the subgroup was small (n = 16). While there was no significant difference in the nonpsychiatric admission rate between the ketamine and benzodiazepine cohorts (35% vs. 51%, p = 0.082), nonpsychiatric admissions in the benzodiazepine cohort were largely driven by intubation (63% vs. 3.8%, difference = 59%, 95% CI = 38% to 79%, p < 0.001). CONCLUSIONS: Administration of prehospital ketamine for severe agitation was not associated with an increase in the rate of psychiatric evaluation in the emergency department or psychiatric inpatient admission when compared with benzodiazepine treatment, regardless of the patient's psychiatric history.

Impaired dendritic expression and plasticity of h-channels in the fmr1(-/y) mouse model of fragile X syndrome.

Despite extensive research into both synaptic and morphological changes, surprisingly little is known about dendritic function in fragile X syndrome (FXS). We found that the dendritic input resistance of CA1 neurons was significantly lower in fmr1(-/y) versus wild-type mice. Consistent with elevated dendritic I(h), voltage sag, rebound, and resonance frequency were significantly higher and temporal summation was lower in the dendrites of fmr1(-/y) mice. Dendritic expression of the h-channel subunit HCN1, but not HCN2, was higher in the CA1 region of fmr1(-/y) mice. Interestingly, whereas mGluR-mediated persistent decreases in I(h) occurred in both wildtype and fmr1(-/y) mice, persistent increases in I(h) that occurred after LTP induction in wild-type mice were absent in fmr1(-/y) mice. Thus, chronic upregulation of dendritic I(h) in conjunction with impairment of homeostatic h-channel plasticity represents a dendritic channelopathy in this model of mental retardation and may provide a mechanism for the cognitive impairment associated with FXS.
