Current Trends in Geriatric Emergency Medicine.

The number of geriatric visits to United States emergency departments continues to rise. This article reviews demographics, statistics, and future projections in geriatric emergency medicine. Included are discussions of US health care spending, geriatric emergency departments, prehospital care, frailty of geriatric patients, delirium, geriatric trauma, geriatric screening and prediction tools, medication safety, long-term care, and palliative care.

Vertigo, vertebrobasilar disease, and posterior circulation ischemic stroke.

Dizzy patients present a significant diagnostic challenge to the emergency clinician. The discrimination between peripheral and central causes is important and will inform subsequent diagnostic evaluation and treatment. Isolated vertigo can be the only initial symptom of a posterior circulation stroke. The sensation of imbalance especially raises this possibility. Research involving strokes of the posterior circulation has lagged behind that of the anterior cerebral circulation. Investigations of the last 20 years, using new technologies in brain imaging in combination with detailed clinical studies, have revolutionized our understanding of the clinical presentation, causes, treatments, and prognosis of posterior circulation ischemia.

Impact of an emergency department closure on the local emergency medical services system.

BACKGROUND: On July 12, 2010, Boston Medical Center (BMC), the busiest emergency department (ED) in Massachusetts, with more than 100,000 adult patient visits per year, consolidated its two fully functional EDs into one. In preparation for this consolidation, BMC implemented systems changes to mitigate potential negative effects on both BMC and emergency medical services (EMS) providers, including Boston Emergency Medical Services (Boston EMS), the provider of 9-1-1 EMS to the City of Boston. OBJECTIVE: To examine the impact of the closure of an ED on an urban EMS system in a setting where ambulance diversion is not allowed. METHODS: We performed a before-and-after study that examined the effects of an ED closure on BMC and Boston EMS. We examined ED and Boston EMS volumes and ambulance turnaround intervals from June 1, 2010, to July 11, 2010 (preclosure) as compared with July 12, 2010, to August 26, 2010 (postclosure). Mean ED and Boston EMS volumes and Boston EMS turnaround intervals were calculated in four-hour shifts. We used multivariate analysis to analyze electronic medical systems data from BMC and Boston EMS and linear regression. We used autoregressive integrated moving average (ARIMA) models to determine the effect of the ED closure on turnaround intervals, ED volumes, and transport volumes. All analyses were adjusted for shift, ED volume, day of the week, and citywide EMS transport volumes. RESULTS: After ED closure, there was a statistically significant increase of 0.89 minutes (p = 0.02) in the mean EMS turnaround intervals. Additionally, the total ED volume decreased by 3.67 visits per shift (p < 0.001). The ratio of patients transported by Boston EMS to BMC remained unchanged (p = 0.11) for two weeks before and two weeks after the closure. CONCLUSIONS: The closure of one ED resulted in a statistically significant increase in turnaround intervals and a significant decrease in ED volume independent of EMS volumes. In the absence of ambulance diversion, ratios of EMS turnaround intervals and EMS volumes according to hospital destination can be used as alternatives to ambulance diversion times to examine the effects of system-level changes such as closure of an ED on an urban EMS system.

Managing emergency department overcrowding.

Emergency department (ED) crowding and ambulance diversion has been an increasingly significant national problem for more than a decade. More than 90% of hospital ED directors reported overcrowding as a problem resulting in patients in hallways, full occupancy of ED beds, and long waits, occurring several times a week. Overcrowding has many other potential detrimental effects including diversion of ambulances, frustration for patients and ED personnel, lesser patient satisfaction, and most importantly, greater risk for poor outcomes. This article gives a basic blueprint for successfully making hospital-wide changes using principles of operational management. It briefly covers the causes, significance, and dangers of overcrowding, and then focuses primarily on specific solutions.

Emergency Department overcrowding and ambulance diversion: the impact and potential solutions of extended boarding of admitted patients in the Emergency Department.

Emergency Department (ED) crowding and ambulance diversion have been increasingly significant national problems for more than a decade. Surveys of hospital directors have reported overcrowding in almost every state and 91% of hospital ED directors report overcrowding as a problem. The problem has developed because of multiple factors in the past 20 years, including a steady downsizing in hospital capacity, closures of a significant number of EDs, increased ED volume, growing numbers of uninsured, and deceased reimbursement for uncompensated care. Initial position statements from major organizations, including JCAHO and the General Accounting Office, suggested the problem of overcrowding was due to inappropriate use of emergency services by those with no urgent conditions, probably cyclical, and needed no specific policy response. More recently, the same and other organizations have more forcefully highlighted the problem of overcrowding and focused on the inability to transfer emergency patients to inpatient beds as the single most important factor contributing to ED overcrowding. This point has been further solidified by initial overcrowding research. This article will review how overcrowding occurred with a focus on the significance and potential remedies of extended boarding of admitted patients in the Emergency Department.

Elder abuse.

Elder abuse and neglect is a prevalent, underrecognized problem among today's senior citizens. Fortunately, awareness is increasing, and services are being provided to elders on a more ready basis. Still, the emergency care provider must act as a patient advocate and assume responsibility for the detection, treatment, and safe disposition of unfortunate victims.

Diagnosis and management of dizziness and vertigo.

Dizziness and vertigo present in patients of all ages. Particularly in older patients, dizziness is associated with a variety of cardiovascular, neurosensory, and psychiatric conditions and with the use of multiple medications. For the patient, the symptoms can be debilitating. In patients older than 60 years, 20% have experienced dizziness severe enough to affect their daily activities. Appropriate diagnosis and treatment can significantly improve quality of life. Most causes of dizziness are benign, but early recognition of serious or life-threatening disease is important. Management of these patients includes referral for neuroimaging and further evaluation in an emergency department.

Submersion.

Many thousands of individuals are submersion victims each year in the United States. The majority of victims are young, previously healthy people. There have been no recent breakthroughs in medical technology or treatment modalities that have improved survival rates for submersion victims. The key to their successful outcome and return to productive, full lives is aggressive resuscitation by emergency physicians and prehospital care providers. Most submersion incidents should never take place. Emergency physicians can take the lead in public education and prevention.

Influenza.

Influenza is a major killer and world health problem. Infection rates are highest in children, but complication rates are highest in the elderly, patients with chronic pulmonary and cardiovascular disease, immunosuppressed patients, and diabetics. Widespread vaccination, particularly of individuals at high risk, is crucial in decreasing incidence, controlling epidemics, and reducing complications. A new class of antiviral drugs, the neuraminidase inhibitors, has been shown to be effective in reducing time to alleviation of symptoms, close contact prophylaxis, and reducing complications of high risk individuals.

Flumazenil reversal of lorazepam-induced acute delirium.

We report the case of a 63-year-old man who presented to the Emergency Department (ED) with a 1-week history of sore throat, hoarseness and dysphagia. During his ED workup, the patient experienced an acute delirium 25 min after being given 2 mg of Lorazepam. The patient's mentation returned to normal within 1-2 min of being given 1 mg of Flumazenil. We discuss the various behavioral side effects of benzodiazepines and the indications for the use of Flumazenil.
