Effect of hospital staff surge capacity on preparedness for a conventional mass casualty event.

OBJECTIVES: To assess current medical staffing levels within the Hospital Referral System in the City of Cape Town Metropolitan Municipality, South Africa, and analyze the surge capacity needs to prepare for the potential of a conventional mass casualty incident during a planned mass gathering. METHODS: Query of all available medical databases of both state employees and private medical personnel within the greater Cape Town area to determine current staffing levels and distribution of personnel across public and private domains. Analysis of the adequacy of available staff to manage a mass casualty incident. RESULTS: There are 594 advanced pre-hospital personnel in Cape Town (17/100,000 population) and 142 basic pre-hospital personnel (4.6/100,000). The total number of hospital and clinic-based medical practitioners is 3097 (88.6/100,000), consisting of 1914 general physicians; 54.7/100,000 and 1183 specialist physicians; 33.8/100,000. Vacancy rates for all medical practitioners range from 23.5% to 25.5%. This includes: nursing post vacancies (26%), basic emergency care practitioners (39.3%), advanced emergency care personnel (66.8%), pharmacy assistants (42.6%), and pharmacists (33.1%). CONCLUSION: There are sufficient numbers and types of personnel to provide the expected ordinary healthcare needs at mass gathering sites in Cape Town; however, qualified staff are likely insufficient to manage a concurrent mass casualty event. Considering that adequate correctly skilled and trained staff form the backbone of disaster surge capacity, it appears that Cape Town is currently under resourced to manage a mass casualty event. With the increasing size and frequency of mass gathering events worldwide, adequate disaster surge capacity is an issue of global relevance.

Mustard gas or sulfur mustard: an old chemical agent as a new terrorist threat.

Sulfur mustard is a member of the vesicant class of chemical warfare agents that causes blistering to the skin and mucous membranes. There is no specific antidote, and treatment consists of systematically alleviating symptoms. Historically, sulfur mustard was used extensively in inter-governmental conflicts within the trenches of Belgium and France during World War I and during the Iran-Iraq conflict. Longitudinal studies of exposed victims show that sulfur mustard causes long-term effects leading to high morbidity. Given that only a small amount of sulfur mustard is necessary to potentially cause an enormous number of casualties, disaster-planning protocol necessitates the education and training of first-line healthcare responders in the recognition, decontamination, triage, and treatment of sulfur mustard-exposed victims in a large-scale scenario.

Second impact syndrome.

A controversial term first described by Saunders and Harbaugh1 in 1984, Second Impact Syndrome (SIS) consists of two events. Typically, it involves an athlete suffering post-concussive symptoms following a head injury.2 If, within several weeks, the athlete returns to play and sustains a second head injury, diffuse cerebral swelling, brain herniation, and death can occur. SIS can occur with any two events involving head trauma. While rare, it is devastating in that young, healthy patients may die within a few minutes. Emergency physicians should be aware of this syndrome and counsel patients and their parents concerning when to allow an athlete to return to play. Furthermore, we present guidelines for appropriate follow up and evaluation by a specialist when necessary.

International disaster medical sciences fellowship: model curriculum and key considerations for establishment of an innovative international educational program.

As recent events highlight, a global requirement exists for evidence-based training in the emerging field of Disaster Medicine. The following is an example of an International Disaster Medical Sciences Fellowship created to fill this need. We provide here a program description, including educational goals and objectives and a model core curriculum based on current evidence-based literature. In addition, we describe the administrative process to establish the fellowship. Information about this innovative educational program is valuable to international Disaster Medicine scholars, as well as U.S. institutions seeking to establish formal training in Disaster Medical Sciences.

Crowding and delivery of healthcare in emergency departments: the European perspective.

Emergency department (ED) crowding is a multifactorial problem, resulting in increased ED waiting times, decreased patient satisfaction and deleterious domino effects on the entire hospital. Although difficult to define and once limited to anecdotal evidence, crowding is receiving more attention as attempts are made to quantify the problem objectively. It is a worldwide phenomenon with regional influences, as exemplified when analyzing the problem in Europe compared to that of the United States. In both regions, an aging population, limited hospital resources, staff shortages and delayed ancillary services are key contributors; however, because the structure of healthcare differs from country to country, varying influences affect the issue of crowding. The approach to healthcare delivery as a right of all people, as opposed to a free market commodity, depends on governmental organization and appropriation of funds. Thus, public funding directly influences potential crowding factors, such as number of hospital beds, community care facilities, and staffing. Ultimately ED crowding is a universal problem with distinctly regional root causes; thus, any approach to address the problem must be tailored to regional influences.

Surge capacity concepts for health care facilities: the CO-S-TR model for initial incident assessment.

Facility-based health care personnel often lack emergency management training and experience, making it a challenge to efficiently assess evolving incidents and rapidly mobilize appropriate resources. We propose the CO-S-TR model, a simple conceptual tool for hospital incident command personnel to prioritize initial incident actions to adequately address key components of surge capacity. There are 3 major categories in the tool, each with 4 subelements. "CO" stands for command, control, communications, and coordination and ensures that an incident management structure is implemented. "S" considers the logistical requirements for staff, stuff, space, and special (event-specific) considerations. "TR" comprises tracking, triage, treatment, and transportation: basic patient care and patient movement functions. This comprehensive yet simple approach is designed to be implemented in the immediate aftermath of an incident, and complements the incident command system by aiding effective incident assessment and surge capacity responses at the health care facility level.

The current state of hospital-based emergency medicine in Germany.

Germany has a long tradition of having physicians, often anesthesiologists with additional training in emergency medicine, deliver prehospital emergency care. Hospital-based emergency medicine in Germany also differs significantly from the Anglo-American model, and until recently having separate emergency rooms for different departments was the norm. In the past decade, many hospitals have created "centralized emergency departments" [Zentrale Notaufnahme (ZNAs)]. There is ongoing debate about the training and certification of physicians working in the ZNAs and whether Germany will adopt a specialty board certification for emergency medicine.

Ovarian teratoma with torsion masquerading as intussusception in 4-year-old child.

BACKGROUND: Ovarian torsion (OT) occurs primarily in women of child-bearing age, but is rare in the pediatric population. The clinical presentation often consists of nonspecific abdominal complaints making the diagnosis difficult. Radiologic and sonographic evidence can be misleading. Although the delay in diagnosis from symptom onset is common, rapid diagnosis of ovarian torsion is imperative to prevent morbidity. CASE REPORT: We present the case of a four-year-old female who presented to the emergency department (ED) with a five-day history of intermittent abdominal pain and emesis. Initial diagnosis was suspicious for intussusception; however, on operative exploration, she was found to have a right adnexal torsion secondary to an ovarian teratoma. A right salpingo-oophorectomy was performed. CONCLUSION: Early diagnosis of ovarian torsion may increase ovarian salvage and reduce morbidity. Faced with abdominal pain of uncertain etiology in a female child, emergency physicians should include ovarian torsion secondary to an ovarian mass in the differential diagnosis.

Transscalene brachial plexus block: a new posterolateral approach for brachial plexus block.

Depending on the approach to the upper brachial plexus, severe complications have been reported. We describe a novel posterolateral approach for brachial plexus block which, from an anatomical and theoretical point of view, seems to offer advantages. Twenty-seven patients were scheduled to undergo elective major surgery of the upper arm or shoulder using this new transscalene brachial plexus block. The success rate was 85.2% for surgery. Two patients required additional analgesia with IV sufentanil. In two others, regional anesthesia was inadequate. The side effects of this technique included reversible recurrent laryngeal nerve blockade in two patients and a reversible Horner syndrome in one patient. Further studies are needed to compare the transscalene brachial plexus block with other approaches to the brachial plexus.

Surge capacity for healthcare systems: a conceptual framework.

This report reflects the proceedings of a breakout session, "Surge Capacity: Defining Concepts," at the 2006 Academic Emergency Medicine Consensus Conference, "Science of Surge Capacity." Although there are several general descriptions of surge capacity in the literature, there is no universally accepted standard definition specifying the various components. Thus, the objectives of this breakout session were to better delineate the components of surge capacity and to outline the key considerations when planning for surge capacity. Participants were from diverse backgrounds and included academic and community emergency physicians, economists, hospital administrators, and experts in mathematical modeling. Three essential components of surge capacity were identified: staff, stuff, and structure. The focus on enhancing surge capacity during a catastrophic event will be to increase patient-care capacity, rather than on increasing things, such as beds and medical supplies. Although there are similarities between daily surge and disaster surge, during a disaster, the goal shifts from the day-to-day operational focus on optimizing outcomes for the individual patient to optimizing those for a population. Other key considerations in defining surge capacity include psychosocial behavioral issues, convergent volunteerism, the need for special expertise and supplies, development of a standard of care appropriate for a specific situation, and standardization of a universal metric for surge capacity.

The critical airway, rescue ventilation, and the combitube: Part 1.

Emergency and unexpected difficult airway management can rapidly deteriorate into a critical airway event such as "cannot ventilate, cannot intubate" (CVCI). A critical airway event (i.e., inadequate mask ventilation, failed intubation, and CVCI) can be resolved by rescue ventilation, thus avoiding potential neurological disability or death. Recommended options include use of the larygeal mask airway, the esophageal-tracheal Combitube (ETC; Tyco-Healthcare-Nellcor, Pleasanton, Calif), transtracheal jet ventilation, or a surgical airway. This article reviews proper use of the ETC in combination with the self-inflating bulb (SIB) and/or portable carbon dioxide detector to resolve critical airway situations. The combined use of these 3 devices provides on ideal integrated system for airway control and ventilation. In addition, critical airway events and rescue ventilation options; ETC design, technical aspects, training, insertion, and ventilation; determining ETC location (i.e., esophagus vs trachea); and monitoring ETC lung ventilation are reviewed. The SIB primarily assesses ETC location within the esophagus or the trachea; the carbon dioxide detector also permits monitoring lung ventilation. Use of the ETC in prehospital, emergency medicine, and anesthesia settings, including ETC advantages, contraindications, and reported complications will be reviewed in Part 2. How to safely exchange the ETC for a definitive airway also will be reviewed.

The critical airway, rescue ventilation, and the combitube: Part 2.

Emergency and unexpected difficult airway management can rapidly deteriorate into a critical airway event (e.g., inadequate mask ventilation, failed tracheal intubation, or cannot ventilate-cannot intubate). Recommended options to resolve a critical airway event include the laryngeal mask airway, the esophageal tracheal Combitube (ETC; Tyco-Healthcare-Nellcor, Pleasanton, Calif), transtracheal jet ventilation, or a surgical airway to avoid potential neurological disability or death. Part 1, which was published in the February 2004 AANA Journal, reviewed use of the ETC in combination with the self-inflating bulb and/or portable carbon dioxide detector as an effective rescue airway system. Important aspects of rescue ventilation, ETC training methods, how to use the ETC, and determining ETC location also were reviewed. Part 2 reviews ETC advantages, contraindications, and reported complications in prehospital, emergency medicine, and anesthesia settings. Safe methods to exchange the ETC for a definitive airway also are described. Major ETC advantages include the following: (1) easy to learn, (2) can be inserted rapidly, (3) effectively secures the airway, (4) provides adequate lung ventilation, (5) minimizes aspiration risks, (6) facilitates application of high ventilatory pressures, and (7) can be exchanged safely for a definitive airway without compromising airway control or protection.

Death by quinine.

We report a case of a man with a 9.75 g ingestion of quinine. The patient presented with recurrent pulseless wide complex tachycardia for which he received sodium bicarbonate, defibrillation and overdrive mechanical pacing. Despite treatment, the patient died. Quinine is still available for the treatment of leg cramps and drug-resistant malaria. In overdose, quinine affects multiple organ systems, including vision, hearing, the cardiovascular, and renal systems. We review the current approach to quinine intoxication.

International report: current state and development of health insurance and emergency medicine in Germany. The influence of health insurance laws on the practice of emergency medicine in a European country.

Germany has a comprehensive health insurance system, with only 0.183% of the population being uninsured. Access to office-based medicine and to hospitals is easy and convenient. Due to enormous financial pressures, Germany is currently decreasing the number of beds in hospitals, introducing the Diagnosis Related Groups (DRG), and restricting accessibility to specialists. In contrast to Anglo-American countries, Germany follows the concept of bringing the physician to the patient in the prehospital setting, with Emergency Medical Services (EMS) physicians responding to all Advanced Life Support (ALS) calls. Despite a mature EMS system with sophisticated medical equipment and technology, both in the prehospital and hospital setting, logistical issues such as a single emergency telephone number or multidisciplinary Emergency Departments have yet to be established. Within the hospital, this "Franco-German model" considers Emergency Medicine a practice model that does not merit specialty status. Spending restrictions in the health care system, with less access to hospital beds and office-based physicians, will increase the demand for hospital-based emergency care when patients experience problems accessing the medical system. Currently, the German hospital system is unprepared to care for greater numbers of emergency patients. This may call for changes in the German health care system as well as the medical education system, with the introduction of hospital-based Emergency Medicine as its own specialty, similar to Anglo-American countries.

Use of a gum elastic bougie (GEB) in a zone II penetrating neck trauma: a case report.

A 54-year-old man presented with a deep zone II neck injury accompanied by profuse bleeding secondary to attempting suicide by slashing his anterior neck with a knife. Blind passage of the endotracheal tube (ETT) into the glottis through the open anterior neck was unsuccessful. In a second attempt a gum elastic bougie (GEB) was inserted directly through the vocal cord, and "tracheal clicking" and a "hold up" were appreciated. The ETT was then easily fed over the GEB and was successfully passed into the trachea. The patient underwent operative repair and tracheostomy, and he left the hospital 2 days later with his baseline mental status. The use and the benefits of the GEB are reviewed.

Hazardous materials responses in a mid-sized metropolitan area.

OBJECTIVE: To determine the chemicals involved in fire department hazardous materials (hazmat) responses and analyze the concomitant emergency medical services' patient care needs. METHODS: The setting was a mid-sized metropolitan area in the southwestern United States with a population base of 400,000 and an incorporated area of 165 square miles. The authors conducted a retrospective evaluation of all fire department hazmat reports, with associated emergency medical services patient encounter forms, and in-patient hospital records from January 1, 1992, through December 31, 1994. RESULTS: The fire department hazardous materials control team responded to 468 hazmat incidents, involving 62 chemicals. The majority of incidents occurred on city streets, with a mean incident duration of 46 minutes. More than 70% of the responses involved flammable gases or liquids. A total of 32 incidents generated 85 patients, 53% of whom required transport for further evaluation and care. Most patients were exposed to airborne toxicants. Only two patients required hospital admission for carbon monoxide poisoning. CONCLUSION: Most hazmat incidents result in few exposed patients who require emergency medical services care. Most patients were exposed to airborne toxicants and very few required hospitalization. Routine data analysis such as this provides emergency response personnel with the opportunity to evaluate current emergency plans and identify areas where additional training may be necessary.

Survival after ethylene glycol poisoning in a patient with an arterial pH of 6.58.

This ethylene glycol poisoning case had a blood pH of 6.58 and severe hypothermia (30.9 C). The patient received supportive care with dialysis and ethanol therapy. He survived in his premorbid state after 23 days in the hospital. A similar case survived ethylene glycol poisoning neurologicaly intact with an initial pH of 6.46. Although severe acidosis in the presence of serious illness is usually associated with a poor prognosis, our case emphasized the importance of aggressive supportive care and antidotal therapy for ethylene glycol poisoning even when there is a low pH.
