AbstractIntroductionAcute respiratory distress syndrome, a severe manifestation of COVID‐19, prompts the critical intervention of endotracheal intubation (ETI). However, ETI is associated with complications, notably post‐intubation hypotension (PIH), linked to an increased adverse prognosis. Our purpose was to investigate risk factors for PIH in COVID‐19 patients in the emergency department (ED).MethodsThis observational study was conducted at the Afzalipour Hospital, Iran. Adult COVID‐19 patients undergoing ETI were included, with data collected on demographic variables, medical history, and hemodynamic parameters. PIH was defined as the occurrence of any of the following: reduction of systolic blood pressure (SBP) to 90 mmHg or less; reduction of mean arterial pressure (MAP) to 65 mmHg or less; reduction of SBP by at least 20% of the initial value; or the need for vasopressor support during the 30 min after intubation.ResultsAmong 145 patients, the mortality rate was 82.7%, and PIH occured in 22.7%. Univariate analysis revealed associations between PIH and initial SBP (SBP‐0) and initial MAP. Multivariable regression revealed that each 1 mmHg decrease in SBP‐0 increased the risk of PIH by 5%. Patients with SBP‐0 of less than 116 mmHg had a PIH odds ratio of 4.1. A history of hypertension (HTN) or ischemic heart disease (IHD) increased the likelihood of PIH sixfold. The receiver operating characteristic curves for SBP‐0 had an area under the curve (AUC) of 0.67 (95% CI: 0.54–0.79), lower than the AUC of 0.77 (95% CI: 0.64–0.86) for the model incorporating SBP‐0, history of HTN or IHD, and total severity score. Despite this, the Z score comparing the AUCs of SBP‐0 and the multivariable model did not indicate a statistically significant difference.ConclusionsHistory of HTN or IHD, as well as low SBP‐0, are independently associated with an increased risk of PIH in COVID‐19 patients.

AbstractIntroductionAlthough point‐of‐care ultrasound (POCUS) is recognized as a useful diagnostic and prognostic tool during the management of out‐of‐hospital cardiac arrest (OHCA), opposing viewpoints exist. The objectives of this study are to investigate the knowledge, attitude, and practice (KAP) in POCUS utilization during OHCA among emergency medicine (EM) physicians in Hong Kong and to identify their barriers.MethodsA cross‐sectional questionnaire was conducted among EM physicians in 9 accident and emergency departments in Hong Kong. The questionnaire assessed participants' demographics, knowledge, attitude, practices, and barriers on this issue. Composite scores for KAP were calculated. Subgroup analysis and multiple regression analysis were used to explore the correlation between KAP and participants' demographics. Participants' barriers were evaluated by binary and open‐ended questions.ResultsA total of 224 questionnaires were distributed and 150 questionnaires were returned (response rate: 67.0%). Statistically significant associations of knowledge and attitude with practice were demonstrated (both p < 0.001). Independent predictors of more frequent POCUS use in OHCA included EM fellowship status (p = 0.005), receiving training on this issue (p < 0.001), and working in large hospitals (p = 0.007). The top‐ranked barriers were chaotic environment (74%), no structural education on this practice (63%), and the lack of staff (61%).ConclusionsThe knowledge and attitude of performing POCUS during OHCA were demonstrated to enhance EM physicians' practice. By improving physicians' knowledge and removing the possible barriers they are facing, POCUS can be optimally utilized during OHCA to improve patient care.

AbstractObjectiveTo evaluate the prevalence of burnout, its underlying personal or occupational stressors, and impact on individual well‐being and patient care.DesignCross‐sectional survey.ParticipantsAll emergency physicians in the public and the private sector in Hong Kong.MethodSelf‐administered, anonymous, voluntary questionnaires were distributed in physical and electronic forms from April to June 2022. Burnout was assessed by the Maslach Burnout Inventory (MBI). Stressors were assessed by questions on demographic, occupational, and social background. Impact was assessed by the Patient Health Questionnaire‐9 (PHQ‐9) for depression and questions on job satisfaction and self‐perceived patient care.ResultsThe response rate was 37.8% (n = 241). Prevalence of high overall burnout was 28.2% (n = 68), with 47.7% (n = 115) having high emotional exhaustion, 63.1% (n = 152) high depersonalization, and 56% (n = 135) low personal accomplishment. A higher burnout rate was observed in younger age, female, not married, job position (associate consultant, resident specialist, and higher trainee), working on shift duty, more night shifts, and consecutive shifts. Burnout is also associated with depression, suicidal idea, consideration of quitting, less job satisfaction, and less favorable patient care (p < 0.05).ConclusionBurnout is prevalent in emergency physicians in Hong Kong, and its impact on individual well‐being and clinical care was evident. A higher burnout rate was observed in younger doctors and also fellows. Identified stressors such as shift pattern should be addressed and potentially improved. Further strategies should be explored to reduce burnout in our colleagues.

AbstractBackgroundOlder patients face increased sepsis risk, requiring precise prognostic tools in the emergency department (ED). This study aimed to explore factors predicting 28‐day mortality among older (≥60 years) patients with suspicion of sepsis in the ED.MethodsWe performed a retrospective cohort study. Data for all older patients with clinical suspected sepsis presenting to the ED from 1 October 2018 to 31 December 2018, were collected. Prognostic factors, characteristics, comorbidities, vital signs at triage, the emergency severity score, initial laboratory results, and sepsis bundle treatment were analyzed using univariable and multivariable Cox regression. Hazard ratios (HR) were calculated using these analytical methodologies to prognosticate 28‐day mortality.ResultsA total of 329 older patients with suspected sepsis were included. The overall 28‐day mortality was 10.33%. Independent prognostic factors that were significantly associated with 28‐day mortality were malignancy (adjusted hazard ratio [aHR]: 3.67; 95% confidence interval [CI]: 1.90, 7.09; p < 0.01), oxygen saturation ≤93% (aHR: 3.37; 95% CI: 1.79, 3.43; p < 0.01), and dependent status (hazard ratio [HR]: 2.27; 95% CI: 1.14, 4.53; p = 0.02).ConclusionsThis study suggests that “MOD”; M‐Malignancy, O‐Oxygen saturation ≤93%, and D‐Dependent status are significant prognostic indicators for 28‐day mortality among older patients with suspected sepsis in the ED.Trial registrationThe trial was retrospectively registered in the Thai Clinical Trial Registry on 06/05/2022, identification number TCTR20220506006.
