Incidence of unknown COVID-19 infection in a cohort of emergency physicians and advance practice providers.

INTRODUCTION: In United States, health care workers have been immersed in the COVID-19 pandemic since February 2020. Since availability of COVID-19 vaccines, there is limited literature investigating the incidence of unknown COVID-19 infections in physicians and Advanced Practitioner Providers (APPs) working in emergency departments (EDs). The primary objective is to determine the incidence unknown COVID-19 infection within a cohort of emergency physicians (EPs) and APPs. METHODS: Prospective observational study at a tertiary academic center with emergency medicine residency and 64,000 annual ED visits. EPs/APPs providing care to ED patients over the prior 12 months were eligible. Serum samples were collected between May 1 and June 30, 2022. Analysis utilized Luminex xMAP® SARS-CoV-2 Multi-Antigen IgG Assay for antibodies to Nucleocapsid, Receptor-binding domain, and Spike subunit 1. Mean Fluorescent Intensity (MFI) ≥ 700 was considered positive. Subjects completed 12 question survey assessing demographics and previously confirmed COVID-19 infection. Fisher's exact test evaluated associations of demographics and clinical characteristics with confirmed COVID-19 status. Analyses performed using SAS, Version 9.4. P < 0.05 considered statistically significant. RESULTS: Sixty-nine of 81 eligible subjects (85.2%) participated, 58.0% were male, 97.1% white, with mean age of 37. Eighteen subjects had MFI ≥ 700 strongly suggestive of prior infection, with 17.7% unknown. No statistically significant difference between age, gender, race, children in home, or household member with previously COVID-19 infection. CONCLUSION: Unknown previous COVID-19 infection was less then expected in this cohort of EPs/APPs, and no association with individual characteristics, previously infected household member, or children in the home.

Determining presentation skills gaps among healthcare professionals.

Healthcare professionals frequently communicate complex medical information among colleagues and students. This paper aims to determine gaps in healthcare professionals' presentation skills and identify barriers to improving. Eighty-eight individuals at a Midwest Academic Medical Center completed a survey that consisted of three parts: (1) respondents' current presentation slide deck, (2) respondents' perceptions of their current presentation skills, and (3) barriers to and motivations for improving their presentation skills. A mixed-methods approach was used to collect and analyze data. Respondents used bullet points and text the most (74%), and videos the least in their presentations (51%). When assessing respondents' perceptions of their current presentation skills, they rated themselves the lowest as a storyteller (median = 6/10) and as an overall presenter (median = 6/10). The biggest barrier reported was "lack of training on best practices" (58%). Respondents reported "interested in improving" and "enhance opportunities" as their main motivations for improving presentation skills. Four themes emerged from the open-ended survey items: Practical tips and best practices, Ability to communicate effectively, Professional development, and Practice opportunities. Effective presentation skills should be included in every healthcare professionals faculty development curriculum. This is especially crucial for junior faculty members to ensure their continued success.

Novel Barrier Enclosure for Both Aerosol and Droplet Protection Model.

Emergency physicians are on the front lines of treating patients with highly infectious respiratory diseases. Personal protective equipment is one defense against contamination from droplet and aerosol secretions. Intubation is a procedure that greatly can increase provider's risk of exposure. Utilization of an intubation box has been discussed and recommended on social media platforms. There has been scant literature demonstrating the effectiveness of such devices. This study aimed to determine degree of droplet contamination to the intubator utilizing a novel barrier enclosure with a fluorescent simulated respiratory contagion. This model confirmed both added protection to the providers preforming intubation, and reduction of spread of the droplets when such a device is applied to patient care.

Evaluation of a Novel Handoff Communication Strategy for Patients Admitted from the Emergency Department.

INTRODUCTION: Miscommunication during inter-unit handoffs between emergency and internal medicine physicians may jeopardize patient safety. Our goal was to evaluate the impact of a structured communication strategy on the quality of admission handoffs. METHODS: We conducted a mixed-methods, pre-test/post-test study at a 560-bed academic health center with 60,000 emergency department (ED) patient visits per year. Admission-handoff best practices were integrated into a modified SBAR format, resulting in the Situation, Background, Assessment, Responsibilities & Risk, Discussion & Disposition, Read-back & Record (SBAR-DR) model. Physician handoff conversations were recorded and transcribed for the 60 days before (n=110) and 60 days after (n=110) introduction of the SBAR-DR strategy. Transcriptions were scored by two blinded physicians using a 16-item scoring instrument. The primary outcome was the composite handoff quality score. We assessed physician perceptions via a post-intervention survey. RESULTS: The composite quality score improved in the post-intervention phase (7.57 + 2.42 vs. 8.45 + 2.51, p=.0085). Three of the 16 individual scoring elements also improved, including time for questions (70.6% vs. 82.7%, p=.0344) and confirmation of disposition plan (41.8% vs. 62.7%, p=.0019). The majority of emergency and internal medicine physicians felt that the SBAR-DR model had a positive impact on patient safety and handoff efficiency. CONCLUSION: Implementation of the SBAR-DR strategy resulted in improved verbal handoff quality. Agreement upon a clear disposition plan was the most improved element, which is of great importance in delineating responsibility of care and streamlining ED throughput. Future efforts should focus on nurturing broader physician buy-in to facilitate institution-wide implementation.

A description of teaching methods using an on-site instructor versus a distant site instructor to train laryngoscopy to medical students in Hanoi, Vietnam, from Omaha, Nebraska, by video communication.

This study demonstrated a method to train medical students at Hanoi Medical School in airway management from Omaha, Nebraska, using tele-mentoring techniques. Correct placement of the endotracheal tube was documented by tele-broncoscopy following intubation. This technology may increase medical training capabilities in remote or developing areas of the world. Medical care delivery could be performed using this technology by tele-mentoring a lesser trained medical provider at a distant site enabling them to accomplish complex medical tasks.

Milk-alkali-induced pancreatitis in a chronically hypocalcemic patient with DiGeorge syndrome.

BACKGROUND: Pancreatitis is a common diagnosis in the emergency department (ED), and milk-alkali syndrome (MAS) is an uncommon etiology for pancreatitis. MAS is caused by increased calcium and alkali ingestion, causing hypercalcemia accompanied by metabolic alkalosis and renal failure. Once considered rare, MAS is an increasingly common cause of hypercalcemia. Awareness of the resurgence of this syndrome is important for emergency physicians when recalling the causes of renal failure and pancreatitis. We present a case of pancreatitis and acute renal failure (ARF) in a chronically hypocalcemic DiGeorge syndrome patient, resulting from hypercalcemia secondary to excessive ingestion of calcium carbonate tablets. CASE REPORT: A patient with DiGeorge syndrome and chronic abdominal pain due to gastroesophageal reflux disease (GERD) presented to our ED for severe abdominal pain. He reported nausea and vomiting, as well as epigastric pain that seemed worse than his typical pain. Laboratory evaluation revealed pancreatitis and ARF, although the patient had no prior history of these conditions. Upon further questioning, his mother divulged that the patient had been taking large quantities of calcium carbonate tablets for his worsening GERD symptoms. The patient was admitted to the intensive care unit where his pancreatitis and ARF eventually resolved as his calcium levels returned to his baseline. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: MAS is a relatively uncommon diagnosis, but can lead to serious sequelae such as pancreatitis and ARF. Questioning the patient about calcium ingestion is an important facet to the diagnosis and work-up of pancreatitis and ARF. Recognition of this etiology can improve patient outcomes and prevent recurrences.

Comparison of Airtraq optical laryngoscope and Storz video laryngoscope in a cadaver model.

BACKGROUND: Airway management in the emergency department is a critical intervention that requires both standard techniques and rescue techniques to ensure a high rate of success. Recently, video laryngoscope (VL) systems have become increasingly common in many large urban EDs, but these systems may exceed the budgets of smaller rural EDs and EMS services and the Airtraq optical laryngoscope (OL) may provide an effective, low-cost alternative. We hypothesized that laryngeal view and time to endothracheal tube placement for OL and VL intubations would not be significantly different. METHODS: This was a prospective, crossover trial. SETTING: University-based emergency medicine residency program procedure laboratory utilizing lightly embalmed cadavers. SUBJECTS: PGY1-3 emergency medicine residents. The study subjects performed timed endotracheal intubations alternately using the OL and VL. The subjects then rated the Cormack-Lehane laryngeal view for each device. STATISTICAL ANALYSIS: Mean time to intubation and the mean laryngeal view score were calculated with 95% confidence intervals and statistical significance was determined by Student's t test. RESULTS: Fourteen subjects completed the study. The average laryngeal view achieved with the OL vs. the VL was not significantly different, with Cormack-Lehane grade of 1.14 vs. 1.07, respectively. Time to endotracheal intubation, however, was significantly different (P<0.001) with the average time to intubation for the OL 25.49 seconds (95% CI: 17.95-33.03) and the VL 13.41 seconds (10.27-16.55). CONCLUSION: The Airtraq OL and the Storz VL yielded similar laryngeal views in the lightly embalmed cadaver model. Time to endotracheal tube placement, however, was less for the VL.
