Slow on the Draw-ED Management of Elevated BP in Older Adults.

PURPOSE OF REVIEW: The purpose of this study is to review data surrounding the emergency department management of elevated blood pressure in older adults, including the management of hypertensive crisis and outpatient management of markedly elevated blood pressure. RECENT FINDINGS: Acute lowering of blood pressure in older adults with markedly elevated blood pressure may lead to serious complications without improvements in hospital length of stay, return visits, or mortality. Older adults presenting with elevated blood pressures without evidence of end-organ damage should be referred for outpatient management of their blood pressure. Treatment of hypertensive emergency should follow standard guidelines with additional considerations for aging physiology. Acute lowering of elevated blood pressure in older adults without evidence of end-organ damage has the potential for harm. If the emergency physician opts to acutely treat, they should consider the increased risk of side effects in older adults and avoid Beers list medications including short-acting nifedipine and clonidine.

The impact of recreational cannabis legalization on ED visit rates for acute cannabis intoxication.

BACKGROUND: In December 2018 the Michigan Regulation and Taxation of Marihuana Act legalized the recreational use of cannabis in Michigan. There are now high potency forms of cannabis readily available in the state, which could result in increased emergency department (ED) visit rates due to intoxication in adults and children. Although cannabis related visits account for a small percentage of all adult and pediatric ED visits, they impose a significant burden on the health care system's resources. This study aimed to assess the impact of the legalization of recreational marijuana on the rate of ED visits for acute cannabis intoxication. METHODS AND DESIGN: We utilized the legalization of marijuana in the state of Michigan to conduct a natural experiment utilizing a retrospective observational cohort design of ED visits for acute intoxication before and after legalization. The study was conducted at a health system composed of eight hospitals in southeast Michigan, including both academic and community hospitals serving a diverse patient population. We estimated monthly cannabis-related ED visits based on cannabis-related ICD-10 discharge codes and total ED visits using electronic health record data from 2016 to 2022. A negative-binomial (NB) regression model was used to estimate the immediate and cumulative changes in cannabis-related ED visit rate after legalization. RESULTS: There were a total of 2177 ED visits from 2066 patients for cannabis intoxication in our study cohort. Of the 2177 visits, 671 were before and 1506 were after legalization. In the univariate analysis, recreational cannabis legalization was associated with an increase in the average cannabis-related ED visit rate (Rate Ratio [RR]:1.70, 95% CI: (1.49, 1.94), p-value <0.001). In the multivariate analysis adjusting for age, results remain significant (RR 1.47, 95% CI (1.29, 1.70), p-value <0.001). The increased visit rate occurred in the first month after legalization; however, the slope of the increasing rate of ED visits were similar before and after cannabis legalization (RR, 1.28, 95% CI (1.07, 1.54), p-value <0.001). CONCLUSIONS: The legalization of recreational cannabis in Michigan was associated with an immediate increase in ED visit rates for acute cannabis intoxications across all ages, especially among middle-aged adults, in the context of an stably increasing ED visit rate.

Emergency Department Treatment of Elevated Blood Pressure in the Headache Patient.

Headache accounts for 1 - 3% of emergency department (ED) visits globally and is associated with elevated blood pressure (BP). It is unclear if anti-hypertensive therapy provides benefits. This retrospective study assessed effects of anti-hypertensive therapy in ED headache patients on rescue analgesic need, hospital admissions, and length of stay (LOS). 1385 patients were included. 366 received anti-hypertensive therapy. The anti-hypertensive therapy cohort was older (p < 0.001) with increased odds of admission (p < 0.001) and 2.385 hrs longer ED LOS (p < 0.001). No difference in rescue analgesia was found (p < 0.429). Anti-hypertensive therapy in hypertensive ED headache patients is associated with increased hospital admission and ED LOS, but no difference in rescue analgesia utilization.

Impact of Electronic Medical Record Alerts on Emergency Physician Workflow and Medical Management.

BACKGROUND: Electronic medical record (EMR) alerts are automated messages that notify the physician of important information. However, little is known about how EMR alerts affect the workflow and decision-making of emergency physicians (EPs). STUDY OBJECTIVES: This study aimed to quantify the number of EMR alerts EPs receive, the time required to resolve alerts, the types of alerts EPs receive, and the impact of alerts on patient management. METHODS: We performed a prospective observational study at a tertiary care ED with 130,000 visits annually. Research assistants observed EPs on shift from May to December 2018. They recorded the number of EMR alerts received, time spent addressing the alerts, the types of alerts received, and queried the EP to determine if the alert impacted patient management. RESULTS: Seven residents and six attending physicians were observed on a total of 17 shifts and 153 patient encounters; 78% (119) of patient encounters involved alerts. These 119 patients triggered 530 EMR alerts. EPs spent a mean of 7.06 s addressing each alert and addressed 3.46 alerts per total patient seen. In total, EPs spent approximately 24 s per patient resolving alerts. Only 12 alerts (2.26%) changed clinical management. CONCLUSION: EPs frequently receive EMR alerts, however, most alerts were not perceived to impact patient care. These alerts contribute to the high volume of interruptions EPs must contend with in the clinical environment of the ED.

The Case of Flecainide Toxicity: What to Look for and How to Treat.

BACKGROUND: Flecainide is a class Ic antidysrhythmic agent used to prevent and treat both ventricular and supraventricular tachycardias, including atrial fibrillation, atrioventricular nodal re-entrant tachycardia, and Wolff-Parkinson-White syndrome. Flecainide can cause serious side effects, including cardiac arrest, dysrhythmias, and heart failure. Despite its growing use, the presenting signs and symptoms of flecainide toxicity are not familiar to most clinicians. In particular, our patient's particular presentation of acute kidney injury (AKI) resulting in flecainide accumulation is high risk for missed diagnosis in the emergency department. CASE REPORT: A 58-year-old woman presented with altered mental status and hypoxia that was later found to be secondary to sepsis. Medical history was notable for atrial fibrillation, for which she was on flecainide. Laboratory results were notable for hypokalemia and an AKI. Her wide complex tachycardia on admission was ultimately attributed to flecainide toxicity in the setting of AKI. Six days after presentation, it was found that her flecainide level was in the toxic range at 2.02 µg/mL (normal range 0.20-1.00 µg/mL, toxic >1.50 µg/mL). WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Flecainide intoxication is rare but serious due to the potential for cardiogenic shock. Its diagnosis can be difficult, as the flecainide serum level may take days to result. This case demonstrates the necessity of keeping flecainide toxicity on the physician's differential for patients who are taking the drug, as well as what electrocardiogram findings suggest it as the etiology. Treatment can be lifesaving if initiated promptly.

Monthly Progression of Emergency Medicine Resident Efficiency: What Can We Expect of Our Residents Throughout Training?

BACKGROUND: Developing the capacity for efficient patient care is essential during emergency medicine (EM) residency training. Previous studies have demonstrated that resident efficiency improves during each year of training. OBJECTIVES: This study assessed the progression of EM resident efficiency monthly and sought to develop a model that describes this progression in terms of patients per hour (pts/h) weighted by month of training. METHODS: We performed a retrospective review of EM resident efficiency as determined by pts/h using EM resident monthly patient logs from a postgraduate year (PGY) 1-3 EM training program. Mean pts/h and standard deviation (SDs) were calculated based on month of training. One-way analysis of variance compared year-to-year training. We formulated several linear regression models to describe this progression. RESULTS: We analyzed 51 consecutive months of patient logs from 110 residents. The mean pts/h for PGY1 was 1.201 (n = 85, SD = 0.241), for PGY2 was 1.497 (n = 82, SD = 0.218), and for PGY3 was 1.676 (n = 80, SD = 0.224). Linear regression was used to describe patients seen per hour by the month of training. A significant regression was found with an R2 of 0.437 and p < 0.000. Over 36 months of training, a resident's predicted pts/h is equal to 1.113 + (0.018 × month of training). CONCLUSIONS: EM resident efficiency increases monthly, with most improvement occurring in the PGY1 year. Understanding this improvement may aid in resident performance evaluation and the understanding of predicted resident workflow.

Are three ports better than one? An evaluation of flow rates using all ports of a triple lumen central venous catheter in volume resuscitation.

BACKGROUND: Poiseuille's law states flow rates are directly proportional to the radius to the 4th power and indirectly proportional to the length of a tube. Because of this property, large bore catheters are commonly used in the resuscitation of the critically ill patient. However, there are no studies comparing simultaneous use of all three lumens of a triple lumen (TL) central venous catheter (CVC) with other catheter types. Our objective was to compare the flow rates of normal saline (NS) through various resuscitation catheters against a TL CVC using all 3 ports. METHODS: We performed a blinded prospective observational study of flow rates utilizing multiple resuscitation catheters. Each catheter type was attached to a 1l bag of NS using standard saline tubing and mean time to infuse 1l of normal saline was determined. Three trials each were completed with and without pressure bags. RESULTS: Simultaneous infusion of NS through all ports of a TL CVC demonstrated no statistically significant difference compared to the following catheters: 16ga peripheral venous catheter (PVC) and 6 Fr CVC with pressure bag. The 14 g PVC and 8.5Fr CVC had statistically significant faster flow rates than the TL CVC both with and without a pressure bag. The 6Fr CVC showed significantly faster flow rates than the TL CVC without a pressure bag. CONCLUSIONS: Simultaneous use of all 3 ports of a TL CVC generates flow rates comparable to many other commonly used resuscitation catheters.

Antihypertensive prescription is associated with improved 30-day outcomes for discharged hypertensive emergency department patients.

Background: Hypertension (HTN) is common in discharged emergency department (ED) patients, yet the short-term outcomes of treating HTN at ED discharge are unclear. This study aimed to investigate whether emergency physician (EP) prescription of oral antihypertensive therapy at ED discharge for hypertensive patients is associated with a decreased 30-day risk of the severe adverse events (AEs), death, and revisits to the ED. Methods: We conducted an observational cohort study assessing the 30-day outcomes of discharged ED patients with HTN, comparing outcomes based on whether antihypertensive therapy was prescribed. All discharged adult ED patients from an eight-hospital system with a diagnosis of HTN from January 2016 to February 2020 were screened, and consisted of a mix of suburban and urban patients with broad ethnic and socioeconomic backgrounds. Patients were categorized into the treatment group if they received a prescription for antihypertensive medication at ED discharge. The primary outcome was severe composite AEs from HTN (aortic catastrophe, heart failure, myocardial infarction, hemorrhagic and ischemic stroke, or hypertensive encephalopathy) within 30 days of ED discharge. The secondary outcomes were death or ED revisit over the same period. Results: The study sample consisted of 93,512 ED visits; 57.5% were female, and mean age was 59.3 years. 4.7% of patients were prescribed antihypertensive treatment at ED discharge. Within 30 days, 0.7% of patients experienced an AE, 0.1% died, and 15.2% had an ED revisit. The treatment group had significantly lower odds of AE (adjusted odds ratio [aOR]: 0.224, 95%CI 0.106-0.416, p < 0.001), and ED revisits (aOR: 0.610, 95%CI 0.547-0.678, p < 0.001), adjusting for age, race, degree of HTN, ED treatment for elevated HTN, Elixhauser comorbidity index, and heart failure history. There was no difference in odds of death 30 days after discharge. Conclusion and relevance: Prescription antihypertensive therapy for discharged ED patients is associated with a 30-day decrease in severe adverse events and ED revisit rate.

Early Emergency Medicine Milestone Assessment for Predicting First-Year Resident Performance.

Introduction: The Accreditation Council for Graduate Medical Education (ACGME) requires emergency medicine (EM) residency training programs to monitor residents' progress using standardized milestones. The first assessment of PGY 1 resident milestones occurs midway through the first year and could miss initial deficiencies. Early assessment of PGY 1 EM resident milestones has potential to identify at-risk residents prior to standard midyear evaluations. We developed an orientation syllabus for PGY 1 residents followed by a milestone assessment. Assessment scores helped predict future milestone scores and American Board of Emergency Medicine (ABEM) In-Training Examination (ITE) scores for PGY 1 residents. Methods: From 2013 to 2020, we developed and implemented Milestone Evaluation Day (MED), a simulation-based day and written exam assessing PGY 1 EM residents during their first month on the 23 ACGME 1.0 milestones. MED stations included a history and physical with verbal presentation, patient simulation, vascular access, wound management, and airway management. MED, Clinical Competency Committee-generated (CCC-generated) milestone, and ABEM ITE scores were averaged and compared utilizing Pearson's correlation coefficient. Results: Of 112 PGY 1 EM residents, 110 (98%) were analyzed over an 8-year period. We observed a moderate positive correlation of MED and CCC-generated milestone scores (r = .34, p < .001). There was a nonstatistically significant weak positive correlation of MED and ABEM ITE scores (r = .13, p = .17). Discussion: An early assessment of EM milestones in the PGY 1 year can assist in the prediction of CCC-generated milestone scores for PGY 1 residents.

A Novel Use of an Electronic Differential Diagnosis Generator in the Emergency Department Setting.

Introduction The ability of electronic differential diagnosis (DDx) tools to generate accurate diagnoses has been well established in simulation and primary care clinical environments. However, the use of such tools has not been well studied in the emergency department (ED). We aimed to characterize the use and perceptions of a DDx tool among emergency medicine (EM) clinicians who were newly provided with access to such a tool. Methods We performed a pilot study investigating the utilization of a DDx tool by clinicians in an ED setting shortly after the tool was introduced. After six months of use, retrospective data were analyzed to characterize the use of the tool among ED clinicians. The clinicians were also surveyed on their perceptions of the use of the tool in the ED setting. Results There were 224 total queries, which were regarding 107 unique patients. The most searched symptoms were related to constitutional, dermatologic, and gastrointestinal complaints whereas symptoms related to toxicology and trauma were less commonly searched. Survey respondents rated the tool favorably, and when not used, reported reasons including forgetting that the tool was available for use, not feeling the need to use the tool, and disruption to workflow. Conclusions Electronic DDx tools may have some utility in assisting ED clinicians in generating a DDx, however, clinician adoption and workflow integration are barriers to their utility.

Emergency department use of an electronic differential diagnosis generator in the evaluation of critically ill patients.

BACKGROUND: Accurate diagnosis is an essential component of managing critically ill emergency department (ED) patients. Electronic diagnosis generators (EDGs) are software tools which assist clinicians in their diagnosis generation; however, they have not been evaluated for use for critical ED patients. We aimed to evaluate the use of an EDG for this population to determine its impact on diagnosis generation and diagnostic testing. METHODS: We performed an observational study on usage of an EDG in the high-acuity area of a tertiary care ED. The EDG was used by residents evaluating each patient in the area. The resident used the EDG when the case was felt to have diagnostic uncertainty and completed a data collection tool. Data were summarized by frequencies. Chi-squared or Fisher's exact tests were used to assess the association of added value of the EDG for diagnosis generation and diagnostic testing. RESULTS: Over the 8-month study period, the EDG was utilized to evaluate 98 critical ED patients, of whom 60% were female, 7% were pediatric, and 46% were elderly. It was used most commonly for gastroenterological, infectious disease/immunologic, metabolic/renal, and neuropsychiatric presentations, and was least used for trauma presentations. Use of the EDG led to a diagnosis not initially considered in 47% of cases and led to additional diagnostic testing in 4% of cases. CONCLUSION: EDGs have some potential to improve diagnosis in critical EM patients by expanding the differential diagnosis and, to a lesser extent, altering diagnostic testing.

Scrotal Pain Caused by a Segmental Testicular Infarct.

CASE PRESENTATION: A 44-year-old Black male presented to the emergency department with left scrotal pain. His initial workup did not identify an etiology of his symptoms; however, he returned the following day with worsening pain and a radiology-performed ultrasound then revealed a segmental testicular infarct. DISCUSSION: Segmental testicular infarcts are a rare, often idiopathic, source of scrotal pain. Diagnosis is made by ultrasound, and repeat imaging may be required if not apparent on initial evaluation. Management is typically conservative although some require surgical intervention.

An electronic medical record-based intervention to improve hepatitis A vaccination rates in the emergency department during a regional outbreak.

BACKGROUND: In response to the severe hepatitis A outbreak that occurred in Michigan between August 2016 and September 2019, our multihospital health system implemented an electronic medical record (EMR)-based vaccination intervention across its nine emergency departments (EDs). The objectives were to explore the impact of this intervention on increasing vaccination rates among high-risk individuals and to assess the barriers to use of a computerised vaccine reminder system. METHODS: All patients who were 18 years or older were screened using an electronic nursing questionnaire. If a patient was at high risk based on the questionnaire, an electronic best practice advisory (BPA) would trigger and give the physician or advanced practice provider the option to order the hepatitis A vaccine. We explored the vaccination rates in the 24-month preintervention and the 18-month intervention periods. We then administered a survey to physicians, advanced practice providers and nurses evaluating their perceptions and barriers to use of the EMR intervention. RESULTS: During the preintervention period, 49 vaccines were ordered (5.5 per 100 000 patient visits) and 32 were administered (3.6 per 100 000 patient visits). During the intervention period, 574 865 patient visits (74.3%) were screened. 2494 vaccines (322 per 100 000 patient visits) were ordered, and 1205 vaccines (155 per 100 000 patients visits) were administered. Physicians and advanced practice providers were initially compliant with the BPA's use, but compliance declined over time. Surveys revealed that the major barrier to use was lack of time. CONCLUSIONS: EMR screening tools and BPAs can be used in the ED as an effective strategy to vaccinate high-risk individuals. This may be translatable to outbreaks of other vaccine-preventable illnesses like influenza, measles or SARS-CoV-2. Providing ongoing education about the public health initiative and giving feedback to physicians, advanced practice providers and nurses about tool compliance are needed to sustain the improvement over time.

The impact of medical scribes on emergency physician diagnostic testing and diagnosis charting.

OBJECTIVES: Since the widespread adoption of electronic medical records (EMRs), medical scribes have been increasingly utilized in emergency department (ED) settings to offload the documentation burden of emergency physicians (EPs). Scribes have been shown to increase EP productivity and satisfaction; however, little is known about their effects on the EP's diagnostic process. We aimed to assess what effect, if any, scribes have on EP diagnostic test ordering and their documentation of differential diagnoses. METHODS: We conducted a retrospective cohort study utilizing a chart review to compare diagnostic practices of EPs working both with and without scribes. We analyzed the number of laboratory and radiologic diagnostic studies ordered per encounter as well as characteristics of differential diagnosis documentation. RESULTS: Scribes did not affect laboratory studies ordered per encounter (mean 6.31 by scribes vs. 7.35 by EPs, difference -1.04; 95% confidence interval [CI] -2.34 to 0.26) or radiologic studies ordered per encounter (mean 1.49 by scribes vs. 1.39 by EPs, difference 0.10; 95% CI -0.15 to 0.35). Scribes did not affect the frequency of documenting a differential diagnosis or the number of diagnoses considered in each differential, but they were associated with higher word counts in EP differentials (mean 72.29 by scribes vs. 50.00 by EPs, mean difference 22.79; 95% CI 6.77 to 38.81). CONCLUSIONS: Scribe use does not appear to affect EP diagnostic test ordering but may have a small effect on their documentation of differential diagnoses.

Novel tool for assessing the quality of feedback in the emergency room (FEED-ER).

BACKGROUND: The Accreditation Council for Graduate Medical Education (ACGME) emphasizes constructive feedback as a critical component of residency training. Despite over a decade of using competency-based milestone evaluations, emergency medicine (EM) residency programs lack a standardized method for assessing the quality of feedback. We developed two novel EM-specific feedback surveys to assess the quality of feedback in the ER (FEED-ER) from both the resident and the faculty perspectives. This study aimed to evaluate the surveys' psychometric properties. METHODS: We developed FEED-ER using a Likert scale with faculty and resident versions based on the ACGME framework and a literature review. The preliminary survey consisted of 25 questions involving the feedback domains of timeliness, respect/communication, specificity, action plan, and feedback culture. We conducted two modified Delphi rounds involving 17 content experts to ensure respondent understanding of the items, item coherence to corresponding feedback domains, thematic saturation of domain content, and time duration. A multicenter study was conducted at five university-based EDs in the United States and one in Thailand in 2019. We evaluated the descriptive statistics of the frequency of responses, validity evidence, and reliability of FEED-ER. RESULTS: A total of 147 EM faculty and 126 EM residents completed the survey. Internal consistency was adequate (Cronbach's alpha > 0.70) and test-retest reliability showed adequate temporal stability (ICC > 0.80) for all dimensions. Content validity was deemed acceptable (CVC > 0.80) for all items. From the 25 items of FEED-ER, 23 loaded into the originally theorized dimensions (with factor loadings > 0.50). Additionally, the five feedback domains were found to be statistically distinct, with correlations between 0.40 and 0.60. The final survey has 23 items. CONCLUSIONS: This is the first study to develop and provide validity evidence for an EM-specific feedback tool that has strong psychometric properties, is reproducible and reliable, and provides an objective measure for assessing the quality of feedback in the ED.

Mondor's Disease: A Rare Cause of Chest Pain in the Emergency Department.

Thrombophlebitis of a subcutaneous vein, known as Mondor's disease, is a rare cause of chest pain and can mimic several more life-threatening diseases. Mondor's disease can be caused by trauma, or hypercoagulable states; however, in many cases the etiology is unknown. Mondor's disease is usually self-limited and can be managed conservatively. In this case report, we highlight a 52-year-old male patient who presented to our emergency department with chest pain caused by Mondor's disease mimicking a pulmonary embolism. Although a rare and benign diagnosis, Mondor's disease should be part of the differential diagnosis of chest pain and can be made on the basis of a thorough history and physical examination alone. Recognition of Mondor's disease could reduce costs and risks of further testing for patients presenting with chest pain.

SPRINT Through Tasks: A Novel Curriculum for Improving Resident Task Management in the Emergency Department.

Introduction: The emergency department (ED) presents a challenging task-management environment to emergency medicine (EM) trainees. However, equipping residents with a tool to improve task switching (generically known as multitasking) could have positive impacts on patient care and physician emotional state. We designed a task-management tool and educational curriculum with the goal of improving emergency medicine resident task-switching ability. Methods: The task-management tool uses the acronym SPRINT: (1) stabilize critical patients, (2) perform procedures, (3) rack (see new patients in the chart rack), (4) in or out (reassess and disposition), (5) type it up (chart completion). These tasks and their order were decided on by two seasoned clinicians based on their years of experience in the ED. The SPRINT tool was taught to EM residents through a 1-hour curriculum consisting of an introductory video, a classroom-based workshop with multimedia didactics, and team learning with a card game simulating the use of the SPRINT tool on a shift. Residents were surveyed to evaluate their task-management confidence and perceived effectiveness of the curriculum. Results: A total of 34 EM residents participated in this training on the SPRINT tool. There was an improvement in resident confidence in task management, and residents reporting having a strategy for task prioritization 8 weeks after the workshop. Discussion: The SPRINT curriculum provides EM residents with a tool to manage the complex task-management environment of the ED. Further research in task-management education should focus on patient-oriented outcomes among physicians who have received this training.
