A Novel, Low-cost, Low-fidelity Pericardiocentesis Teaching Model.

INTRODUCTION: Pericardiocentesis is a high-risk/low-frequency procedure important to emergency medicine (EM). However, due to case rarity it is not often performed on a patient during residency training. Because the coronavirus disease 2019 pandemic limited cadaver-based practice, we developed a novel, low-cost, low-fidelity pericardiocentesis model using three dimensional-printing technology to provide advances on prior home-made models. METHODS: Residents watched a 20-minute video about performing a pericardiocentesis and practiced both a blind and ultrasound-guided technique. We assessed model fidelity, convenience, and perceived provider competence via post-workshop questionnaire. RESULTS: A total of 24/26 (93%) individuals practicing on the ultrasound-guided model and 22/24 (92%) on the blind approach model agreed or strongly agreed that the models reasonably mimicked a pericardial effusion. CONCLUSION: Our low-cost, low-fidelity model is durable, mimics the clinical case, and is easy to use. It also addresses known limitations from prior low-fidelity models.

A Case of Hyperkalemia Versus Pseudohyperkalemia in Chronic Lymphocytic Leukemia.

INTRODUCTION: Both hyperkalemia and pseudohyperkalemia occur in the emergency department. True hyperkalemia necessitates emergent treatment while pseudohyperkalemia requires recognition to prevent inappropriate treatment. It is imperative that the emergency physician (EP) have an understanding of the causes and clinical presentations of both phenomena. CASE REPORT: We present a case of an 88-year-old male with chronic lymphocytic leukemia (CLL) and suspected blast crisis who was found to have elevated serum potassium levels without other manifestations of hyperkalemia and eventually was determined to have pseudohyperkalemia due to white cell fragility. DISCUSSION: Differentiation of hyperkalemia and pseudohyperkalemia is a critical skill for the EP. We discuss multiple causes of hyperkalemia and pseudohyperkalemia in an effort to broaden the knowledge base. CONCLUSION: We present a case of CLL as an unusual cause of pseudohyperkalemia and review common causes of pseudohyperkalemia.

Perceptions in rib injuries: A multidisciplinary single center survey of clinician differences in risk stratification and management of patients with rib fractures.

BACKGROUND: Although associated with significant morbidity, there is no universally accepted management of rib fractures. We hypothesized that variations in risk stratification may influence this. METHODS: A questionnaire was developed to assess providers' perceived risk factors and injury stratification of rib fracture patients at a Level 1 trauma center. RESULTS: There were 143 responses (36% physician response rate). Hypoxia, age, number of ribs fractured, pre-existing pulmonary disease, and flail chest were identified as the most important risk factors determining morbidity and mortality in blunt chest trauma. While clinicians agreed on predicted mortality for <2 fractured ribs, significant variation for 5-6 and >8 rib fractures was seen. EM and surgery providers significantly differed in assessment of injury severity. CONCLUSION: Providers identified common risk factors for increased morbidity and mortality. However, the difference in perceived severity between providers indicates a need for clinical tools to assist in better standardizing rib fracture management.

Patient Characteristics Associated with Comfort Care among Trauma Patients at a Level I Trauma Center.

Trauma patients admitted to the intensive care unit are a unique population with high mortality. This study aims to identify characteristics predicting the likelihood of progressing to palliative management often referred to as comfort care measures, thus enabling the trauma team to broach end-of-life decisions earlier in these patients' care. This is a retrospective analysis of the prospectively collected New York State Trauma Registry database for a single Level I trauma center for patients admitted from 2008 to 2015. During this time, a total of 13,662 patients were admitted to the trauma service and there were 827 deaths, resulting in a crude annual mortality rate of approximately 6 per cent. Approximately one-half of the total mortalities, 404 of 827 (48.9%), were ultimately designated as comfort care. Univariate analysis identified the following risk factors for comfort care designation: advanced age, multiple comorbidities, blunt trauma mechanism, traumatic brain injury, and admission location. Multivariate analysis confirmed advanced age and traumatic brain injury. Subgroup analysis also identified advanced directives, pre-existing dementia, and bleeding disorders as significant associations with comfort care designation. The identification of factors predicting comfort care will result in improved care planning and resource utilization.

Enabling Donation after Cardiac Death in the Emergency Department: Overcoming Clinical, Legal, and Ethical Concerns.

BACKGROUND: In light of the growing gap between candidates for organ donation and the actual number of organs available, we present a unique case of organ donation after cardiac death. We hope to open a discussion regarding organ procurement from eligible donors in the prehospital and emergency department setting. CASE: This case study, involving an otherwise healthy man who, after suffering an untimely death, was able to successfully donate his organs, highlights the need to develop an infrastructure to make this type of donation a viable and streamlined option for the future. DISCUSSION: Given the departure from traditional practice in United States transplantation medicine, we bring forth legal and ethical considerations regarding organ donation in the emergency department. We hope that this case discussion inspires action and development in the realm of transplant medicine, with the aim of honoring the wishes of donors and the families of those who wish to donate in a respectful way, while using our medical skills and technologies to afford candidates who are waiting for organs a second chance. CONCLUSIONS: We believe that this case shows that donation after cardiac death from the emergency department, while resource-intensive is feasible. We recognize that in order for this to become a more attainable goal, additional resources and systems development is required.

An evaluation of resident work profiles, attending-resident teaching interactions, and the effect of variations in emergency department volume on each.

OBJECTIVES: This study examines the effect of variations in emergency department (ED) volume on physician work efficiency (new patients per hour) and work profile (patient-related activities, including both direct and indirect patient care) and whether these differ between first- (Postgraduate Year [PGY]1) and third- (PGY3) year residents. The authors also determine if changes in volume are associated with changes in teaching interactions between attending and resident physicians. METHODS: This was a prospective observational study of resident and attending physicians in the ED. Research assistants (RAs) followed ED residents during clinical shifts and recorded a multitude of data including the amount of time spent in specific activities, the number of new patients seen, and the frequency of attending physician teaching interactions. RESULTS: Third-year residents see more new patients per hour (1.79 vs. 1.16, p < 0.001) than do their first-year counterparts. In addition, third-year residents spend almost 50% less time with each patient (10.7 minutes vs. 19.4 minutes, p < 0.001), and first-year residents spend three times as much time per shift discussing patients with attending physicians (59.4 minutes vs. 27.3 minutes, p = 0.002). More of the PGY1/attending interactions resulted in educational exchanges (54.9% vs. 34.6%, p = 0.003). PGY1 residents also spend more time on dictations per patient (9.6 minutes vs. 5.4 minutes, p = 0.01) and more time on paperwork per patient (18.5 minutes vs. 6.5 minutes, p = 0.007). As ED volume tripled, PGY1 residents were able to increase their patient load to a greater extent than were PGY3 residents by decreasing the length of each patient encounter as volume increased. Overall, ED volume had no effect on the number of teaching interactions, although the length of exchange decreased as volume increased. CONCLUSIONS: Third-year residents see and carry more patients than do their first-year counterparts. They do so primarily by decreasing the amount of time spent with patients and attendings and working more efficiently overall. However, they are not as capable of altering their work profiles in the face of increased volume as their first-year counterparts. While the length of teaching interactions is decreased as volume increases, the number of those interactions resulting in teaching remains constant regardless of volume.
