Dabigatran is a direct oral anticoagulant thrombin inhibitor approved for stroke prophylaxis in patients with non-valvular atrial fibrillation and prophylaxis or treatment of venous thromboembolism. Since approval, there has been increasing concern regarding bleeding risk, predominantly in the elderly population and those with renal disease. We present a case of an 85-year-old female with an unknown medication history, shortness of breath and severe anemia due to an upper gastrointestinal bleed. ⋯ It was later confirmed that the patient was on sole dabigatran therapy. This case highlights the potential for dabigatran to cause extreme elevation in PT/INR in patients with acute renal failure, which may mimic warfarin-induced coagulopathy. Further, it demonstrates significant, rapid correction of abnormal coagulation assays following administration of idarucizumab in a patient with severe INR elevation and suspected dabigatran use.

Observational Study
QT interval prolongation and the rate of malignant ventricular dysrhythmia and cardiac arrest in adult poisoned patients.
Prolongation of QTc interval, a common electrocardiographic (ECG) abnormality encountered in the toxicology patient, is reportedly associated with an increased risk of malignant ventricular dysrhythmias (MVD), such as ventricular tachycardia (VT, with and without a pulse), ventricular fibrillation (VF), and/or cardiac arrest. Quantifiable cardiac arrest risk in relation to specific QTc interval length is not known in this population. ⋯ The risk of malignant ventricular dysrhythmia, including cardiac arrest, is low in this poisoned patient population with an overall rate of 1.1%. Two-thirds of cardiac arrest cases occurred in patients with normal QTc intervals. When considering patients with prolonged QTc intervals, the rate of cardiac arrest remains very low at 0.8%. Considering QTc greater than 500 ms, the rate of cardiac arrest is 1.7%. Further prospective studies are required to quantify the risk of malignant ventricular dysrhythmias, including cardiac arrest, and its relation to the degree of QTc interval in poisoned patients.

Elderly people, defined by age 65 years and older, made up 18.45% of the Swiss Population in 2018 and their number is projected to rise continuously. Data investigating specific characteristics of this patient subgroup, especially in the emergency setting, is scarce. ⋯ The number of elderly patients admitted to our ED is continuously rising. There was no difference in overall disease burden, number of medications and hospital length of stay between octogenarians and nonagenarians. We identified risk factors for mortality, long hospitalizations and need of placement in a nursing facility.

Since providing timely care is the primary concern of emergency departments (EDs), long waiting times increase patient dissatisfaction and adverse outcomes. Especially in overcrowded ED environments, emergency care quality can be significantly improved by developing predictive models of patients' waiting and treatment times to use in ED operations planning. ⋯ By predicting patients' waiting and treatment times, ED workloads can be assessed instantly. This enables ED personnel to be scheduled to better manage demand supply deficiencies, increase patient satisfaction by informing patients and relatives about expected waiting times, and evaluate performances to improve ED operations and emergency care quality.

Observational Study
Management of the mild traumatic brain injured patient using a multidisciplinary observation unit protocol.
We developed an ED based multidisciplinary observation unit (OU) protocol for patients with mild traumatic brain injury (mTBI). We describe the cohort of patients who were placed in the ED OU and we evaluated if changes to our inclusion and exclusion criteria should be made. ⋯ A period of observation for a pre-defined cohort of patients with mTBI provided a triage plan that could allow appropriate patient management without requiring admission in the majority of subjects.
