RESUMO
Sodium nitrite ingestion poses a considerable public health threat. The incidence of sodium nitrite self-poisoning in the United States has been trending upward since 2017. Our case report describes an intentional sodium nitrite ingestion with favorable outcomes. We highlight the proper treatment of this ingestion with intravenous methylene blue. Sodium nitrite is an oxidizing agent that is commonly found in processed meats, fish, and cheeses as a preservative, antimicrobial, and food coloring agent. It is an odorless, white crystalline powder that has been confused for table salt or granulated sugar. It has become more readily available in large quantities online. Unfortunately, online forums exist that detail how to dose sodium nitrite for suicide. Furthermore, it has been recently discussed in popular news streams after a celebrity died of an overdose. Sodium nitrite toxicity is capable of causing severe methemoglobinemia with high mortality. Prompt identification is crucial. We discuss the important implications in regard to media coverage, imitative suicide, and accessibility of sodium nitrite.
RESUMO
We present three medicolegal cases of medical negligence settled out of court. These cases all involved patients who presented to the emergency department (ED) with a suspected diagnosis of kidney stone. Highlighted are the importance of patient communication, addressing incidental findings found during a patient's ED visit, anticipating complications, and the need for thorough documentation.
RESUMO
Hospital emergency department (ED) operations are affected when critically ill or injured patients arrive. Such events often lead to the initiation of specific protocols, referred to as Resuscitation-team Activation (RA), in the ED of Mayo Clinic, Rochester, MN where this study was conducted. RA events lead to the diversion of resources from other patients in the ED to provide care to critically ill patients; therefore, it has an impact on the entire ED system. This paper presents a data-driven and flexible statistical learning model to quantify the impact of RA on the ED. The model learns the pattern of operations in the ED from historical patient arrival and departure timestamps and quantifies the impact of RA by measuring the deviation of the departure of patients during RA from normal processes. The proposed method significantly outperforms baseline methods based on measuring the average time patients spend in the ED.

INTRODUCTION: Anaphylaxis continues to cause significant morbidity and mortality. Healthcare providers struggle to promptly recognize and appropriately treat anaphylaxis patients. The goal of this study was to characterize anaphylaxis-related malpractice lawsuits. METHODS: We collected jury verdicts, settlements, and court opinions regarding alleged medical malpractice involving anaphylaxis from May 2011 through May 2016 from an online legal database (Thomson Reuters Westlaw). Data were abstracted onto a standardized data form. RESULTS: We identified 30 anaphylaxis-related malpractice lawsuits. In 80% of cases, the trigger was iatrogenic (40% intravenous [IV] contrast, 33% medications, 7% latex). Sixteen (53%) cases resulted in death, 7 (23%) in permanent cardiac and/or neurologic damage, and 7 (23%) in less severe outcomes. Fourteen (47%) of the lawsuits were related to exposure to a known trigger. Delayed recognition or treatment was cited in 12 (40%) cases and inappropriate IV epinephrine dosing was reported in 5 (17%) cases. Defendants were most commonly physicians (n=15, 50%) and nurses (n=5, 17%). The most common physician specialties named were radiology and primary care (n=3, 10% each), followed by emergency medicine, anesthesiology, and cardiology (n=2, 7% each). Among the 30 cases, 14 (47%) favored the defendant, 8 (37%) resulted in findings of negligence, 3 (10%) cases settled, and 5 (17%) had an unknown legal outcome. CONCLUSION: Additional anaphylaxis education, provision of epinephrine autoinjectors or other alternatives to reduce dosing errors, and stronger safeguards to prevent administration of known allergens would all likely reduce anaphylaxis-related patient morbidity and mortality and providers' legal vulnerability to anaphylaxis-related lawsuits.

OBJECTIVES: The objectives were to describe lawsuits against providers for failing to order head computed tomography (CT) in cases of head trauma and to determine the potential effects of available clinical decision rules (CDRs) on each lawsuit. METHODS: The authors collected jury verdicts, settlements, and court opinions regarding alleged malpractice for failure to order head CT in the setting of head trauma from 1972 through February 2014 from an online legal research tool (WestlawNext). Data were abstracted onto a standardized data form. The performance of five CDRs was evaluated. RESULTS: Sixty relevant cases were identified (52 adult, eight children). Of 48 cases with known outcomes, providers were found negligent in 10 cases (six adult, four pediatric), settled in 11 cases (nine adult, two pediatric), and were found not liable in 27 cases. In all 10 cases in which providers were found negligent, every applicable CDR studied would have indicated the need for head CT. In all eight cases involving children, the applicable CDR would have suggested the need for head CT or observation. CONCLUSIONS: A review of legal cases reported in a major online legal research system revealed 60 lawsuits in which providers were sued for failing to order head CTs in cases of head trauma. In all cases in which providers were found negligent, CT imaging or observation would have been indicated by every applicable CDR.

OBJECTIVE: To evaluate the feasibility of a protocol for evaluation of transient ischemic attack (TIA) in an Emergency Department Observation Unit (EDOU), and assess the risk of early stroke after such an evaluation. METHODS: All adult patients presenting to the Emergency Department (ED) with signs and symptoms consistent with TIA were prospectively enrolled in this observational study over a period of 3 years. Patients underwent a standardized TIA evaluation per protocol. Risk of subsequent stroke at 48 h, 1 week, 1 month, and 3 months was prospectively assessed. RESULTS: In total, 418 patients were seen during the study period, and all were evaluated per the EDOU TIA protocol. The mean age was 73.1 (+/-13.3) years and 53.8% were males. Comorbidities included hypertension in 71.5%, diabetes mellitus in 20.1%, prior TIA in 19.6%, and prior ischemic stroke in 19.6% of the cohort. Brain CT, neurology consult, electrocardiogram, carotid ultrasound, and additional tests were performed, and education was given. A total of 30.4% of the patients were dismissed directly from the EDOU. The risk of stroke at 2 days was 0.96%, at 7 days 1.2%, at 30 days 1.9%, and 2.4% at 90 days. CONCLUSION: An Emergency Department Observation Unit Protocol for TIA is a feasible option for expedited evaluation of these patients.

Dobutamine is commonly administered as a pharmacologic stressor in patients with limitations precluding exercise testing. The case report presented is one of transient complete heart block resulting from dobutamine sestamibi stress testing. Shortly after initiating the dobutamine infusion, the patient became pale and presyncopal, with hypotension and a heart rate of 50 beats per minute. Subsequently, third-degree heart block developed which lasted transiently and resolved. Subsequent cardiac evaluation of the patient revealed no cardiac etiology for her symptoms. Though bradycardia is infrequently noted in patients receiving dobutamine during stress electrocardiogram, complete heart block is a possibility during dobutamine-induced stress echocardiography and must be recognized as a potential risk.

STUDY OBJECTIVE: An emergency department (ED) observation unit protocol for the management of acute onset atrial fibrillation is compared with routine hospital admission and management. METHODS: Adult patients presenting to the ED with atrial fibrillation of less than 48 hours' duration without hemodynamic instability or other comorbid conditions requiring hospitalization were enrolled. Participants were randomized to either ED observation unit care or routine inpatient care. The ED observation unit protocol included pulse rate control, cardiac monitoring, reassessment, and electrical cardioversion if atrial fibrillation persisted. Patients who reverted to sinus rhythm were discharged with a cardiology follow-up within 3 days, whereas those still in atrial fibrillation were admitted. All cases were followed up for 6 months and adverse events recorded. RESULTS: Of the 153 patients, 75 were randomized to the ED observation unit and 78 to routine inhospital care. Eighty-five percent of ED observation unit patients converted to sinus rhythm versus 73% in the routine care group (difference 12%; 95% confidence interval [CI] -1% to 25%]; P=.06). The median length of stay was 10.1 versus 25.2 hours (difference 15.1 hours; 95% CI 11.2 to 19.6; P<.001) for ED observation unit and inhospital care respectively. Nine ED observation unit patients required inpatient admission. Eleven percent of the ED observation unit group had recurrence of atrial fibrillation during follow-up versus 10% of the routine inpatient care group (difference 1%; 95% CI -9% to 11%; P=.93). There was no significant difference between the groups in the frequency of hospitalization or the number of tests, and the number of adverse events during follow-up was similar in the 2 groups. CONCLUSION: An ED observation unit protocol that includes electrical cardioversion is a feasible alternative to routine hospital admission for acute onset of atrial fibrillation and results in a shorter initial length of stay.

The last decade has seen extraordinary advances in the cardiovascular arena, particularly in the evaluation and management of the patient who has acute coronary syndromes. From bedside markers of myocardial damage to drug-eluting stents, technical advances are proliferating. Efforts in developing an international registry for acute aortic dissection have helped elucidate the acute presentation, management, and prognosis of this uncommon but lethal disease. Finally, the multiple research efforts in coordinating clinical decision-making with serologic markers and advanced imaging for the diagnosis of pulmonary embolism is changing the approach to the patient at risk for thromboembolic disease.

Chest pain is among the most frequently evaluated presenting complaints in the emergency department (ED). Diagnostic etiologies range from benign to life-threatening. Failure to diagnose the life-threatening chest emergencies-specifically acute coronary syndrome, aortic dissection, and pulmonary embolism-can lead to catastrophic medical and legal outcomes for the patient and physician respectively. This article focuses on clinical and risk management strategies to minimize misdiagnosis and produce favorable medical and medicolegal outcomes.

Subarachnold hemorrhage (SAH) is a relatively common cause of cardiopulmonary arrest (CPA). Long-term survival with SAH and CPA is rare, and the vast majority of those who survive have moderate to severe neurologic disability. To our knowledge, there are no prior reports of patients with SAH who experience CPA and survive without neurologic deficit. We describe a patient with SAH who experienced CPA shortly after hospital admission and survived without neurologic sequelae (Cerebral Performance Category 1). Prompt defibrillation of SAH-induced ventricular fibrillation and timely neurologic intervention are essential for good neurologic outcome.

OBJECTIVES: To date, no studies in emergency medicine (EM) have addressed the educational value of the Residency Review Committee for Emergency Medicine's (RRC-EM) requirement for patient follow-up (FU). The authors examined whether performance of patient FU improved EM resident education. METHODS: All EM resident FU encounters from September 25, 2001, through September 24, 2002, were documented and analyzed. All EM residents at a regional tertiary referral emergency department (ED) initiated patient FU encounters by entering information regarding patients' initial ED presentations into a Web-based follow-up system (WBFUS), subsequently entered FU information, and indicated whether they thought that the specific FU encounters improved their education (yes/no). Supervising faculty members then reviewed the residents' completed FU entries. Blinded to residents' responses regarding educational utility, faculty members evaluated whether they thought the specific FU encounters were educational for the residents (yes/no). Data entered into the WBFUS were then summarized as percentages. RESULTS: Eight hundred forty-seven FU encounters were completed by 18 EM residents and 29 EM faculty. Ninety-three percent of the FU entries were deemed by at least one evaluator (resident or faculty) to have educational value. Residents found the act of performing FU educational in 81.3% of cases, whereas faculty thought 80.4% were educational for the resident. Although the residents and faculty agreed on the educational value in 75.4% of cases, the overall strength of the agreement was slight to fair (kappa statistic = 0.21). CONCLUSIONS: This study indicates that EM residents and faculty believe that the act of performing patient FU has educational value for EM residents; however, the interobserver agreement between residents and faculty was low.

STUDY OBJECTIVE: We determine which services, if any, an emergency department (ED) could provide to help a patient who left the ED without being seen by a physician wait longer to see a physician. METHODS: In this retrospective observational study, patients who had left the Saint Marys Hospital ED without being seen by a physician were surveyed by telephone. The Saint Marys Hospital ED is a 43-bed facility with an annual patient volume of 77600 located in a city of 82000. Responders were questioned regarding 15 specific services the Saint Marys Hospital ED could provide to help them wait longer. Eligible participants included willing adults, parents accompanying patients younger than 18 years of age, and patients between the ages of 13 and 18 years whose parents granted permission. Participants were excluded if they denied research authorization, did not speak English, refused to participate, or were unable to be contacted. RESULTS: Between April 9, 2001, and July 17, 2001, 20494 patients registered, 172 patients left without being seen, and 152 patients approved research authorization; we attempted to contact these patients. In total, 97 patients, their parents, or their caretakers completed the entire interview (56.4% of those who left without being seen, 63.8% of those with whom contact was attempted). Nearly 85% of responders retrospectively identified "more frequent updates on wait time" and 70.1% identified "the availability of immediate temporary treatments" as services that would have helped them wait longer. Other waiting room services were identified by fewer than half of the responders as potentially helpful in allowing them to wait longer. CONCLUSION: Communication of estimated waiting time and the availability of immediate treatments for minor injuries or symptoms might increase the time patients are willing to wait and therefore might decrease an ED's rate of patients leaving without being seen.

PE is one of the great challenges in medicine. It is a disease that carries with it a high mortality rate, yet no historical piece of information, physical examination finding, or diagnostic modality is perfect at excluding its possibility. Emergency physicians must be vigilant about considering PE in the differential diagnosis of a variety of presenting complaints and must use a variety of diagnostic and therapeutic options as they manage patients with suspected or confirmed PE. The diagnostic options range from bedside diagnostic tests to highly specialized imaging available at only specialized institutions. Knowing the advantages and disadvantages of each of the diagnostic modalities assists the physician in employing the best test. Therapeutic options also vary widely and include anticoagulation, vena caval interruption, systemic thrombolysis, embolectomy, and other therapeutic adjuncts, such as ECMO and inhaled nitric oxide. Similarly, awareness of the indications and contraindications to the varied therapeutic agents ensures appropriate therapy when the diagnosis is made.

OBJECTIVE: To survey physician and nurse attitudes regarding parental presence during painful procedures on children performed in the emergency department (ED) and who should make that decision. METHODS: The design was an anonymous written survey consisting of six clinical scenarios distributed to all staff and resident physicians and nurses in ten EDs at institutions in the United States routinely caring for children. Participants were asked whether parents should remain with children undergoing intravenous (IV) placement, laceration repair, lumbar puncture, conscious sedation, major resuscitation, and major resuscitation with death. They also were asked who should make the decision. RESULTS: The percentage of physicians who responded that parents should be present was 91.3% for peripheral IV start, 93.3% for laceration repair, 65.7% for lumbar puncture, 83.1% for conscious sedation, 31.9% for major resuscitation, and 35.6% for major resuscitation where death was likely. The percentage of nurses who responded that parents should be present was 86.8% for peripheral IV start, 89.6% for laceration repair, 55.0% for lumbar puncture, 74.9% for conscious sedation, 41.4% for major resuscitation, and 54.3% for major resuscitation where death was likely. In 64.8% of the completed surveys, the physicians indicated that they alone or in conjunction with a parent should make the decision. In 61.5% of the completed surveys, the nurses indicated that they should be involved in the decision. CONCLUSIONS: A majority of emergency physicians and nurses indicated parents should be present for some invasive pediatric procedures. However, as the invasiveness of the pediatric procedures increased, fewer physicians and nurses believed that parents should be present.
