Pattern of emergence and the effects of temperature and light on the emergence and survival of heterophyid cercariae (Centrocestus formosanus and Haplorchis pumilio).

Production of the cercariae of Centrocestus formosanus and Haplorchis pumilio was not affected by a 10-day starvation of the snail host Melanoides tuberculata, and there was no circadian rhythm in the pattern of cercarial emergence. Daily average cercarial productions from each snail were 1,643 for C. formosanus and 689 for H. pumilio at 25 C and 500 lux illumination. The number of cercariae was moderately correlated with the size of snail host. The heaviest sheddings ever observed from 1 snail in 24 hr were 63,400 cercariae for C. formosanus and 3,470 cercariae for H. pumilio. The cercariae of C. formosanus could emerge in the dark, but the number was much less than in the light. In contrast, the cercariae of H. pumilio emerged equally well with or without light. Within the temperature range tested, the emergence of cercariae occurred at 15-35 C, but not at 10 C. Shedding of C. formosanus cercariae increased with the rise in ambient temperature, whereas the greatest shedding of H. pumilio cercariae occurred at 25 C. Life-span of the cercariae was temperature-dependent. The most favorable temperature for survival of C. formosanus was 15 C, at which some survived for 160 hr, and 20 C for H. pumilio, with the longest survival of 130 hr.

Mental and social health during and after acute emergencies: emerging consensus?

Mental health care programmes during and after acute emergencies in resource-poor countries have been considered controversial. There is no agreement on the public health value of the post-traumatic stress disorder concept and no agreement on the appropriateness of vertical (separate) trauma-focused services. A range of social and mental health intervention strategies and principles seem, however, to have the broad support of expert opinion. Despite continuing debate, there is emerging agreement on what entails good public health practice in respect of mental health. In terms of early interventions, this agreement is exemplified by the recent inclusion of a "mental and social aspects of health" standard in the Sphere handbook's revision on minimal standards in disaster response. This affirmation of emerging agreement is important and should give clear messages to health planners.

Early defibrillation by emergency physicians or emergency medical technicians? A controlled, prospective multi-centre study.

UNLABELLED: In a controlled, prospective multi-centre study, defibrillation by emergency medical technicians (EMTs) was compared with the current standard of care in Germany--defibrillation by emergency physicians (EPs)-in order to answer the following questions: can EMTs in a two-tiered emergency medical services (EMS) system with physicians in the field defibrillate earlier than, and as safely as EPs? Does defibrillation by EMTs (study group) affect survival rate and long-term prognosis of patients in ventricular fibrillation (VF), as compared with the current national standards in resuscitation (basic cardiopulmonary resuscitation (CPR) by EMTs, and defibrillation by physicians: control group? METHODS: Prior to the onset of the study, all EMTs completed retraining in basic life support (BLS). Randomly assessed EMTs were then trained to use semi-automatic defibrillators. With the help of on-line tape recordings, the complete resuscitation sequence was evaluated. Follow-up of the patients was carried out with the help of the Glasgow Coma Scale as well as Pittsburgh Cerebral and Overall Performance Categories. RESULTS: A total of 159 patients with VF were included in the study. In 121 cases, collapse was witnessed. Of the patients receiving defibrillation by EMTs 25% were discharged from hospital alive, compared to 24% of the patients defibrillated by EPs. Of the study patients 67% were defibrillated within 12 min, while the percentage of control patients was 46%. Study patients were defibrillated earlier (P < 0.01), the return of spontaneous circulation (ROSC) was achieved earlier (P < 0.05), and the rate of patients requiring no adrenalin during resuscitation was higher in the study group (P < 0.05). The total amount of adrenalin administered in the study group was lower (P < 0.05). No statistically significant differences were found concerning the neurologic long-term prognosis. CONCLUSIONS: In our study, EMT defibrillation was equally effective as defibrillation by EPs, but failed to improve survival rates or long-term outcome of patients in VF significantly, compared to EP defibrillation. Due to a reduction in the time intervals from collapse to defibrillation and to ROSC, as well as in adrenalin doses, by EMT-defibrillation, EMTs in Germany should defibrillate if they reach a patient prior to an EP, provided they have received continuous medical training and supervision.

Emergency pain management: a Canadian Association of Emergency Physicians (CAEP) consensus document.

Pain is the most common presenting complaint heard in Emergency Medicine, yet it is poorly controlled. Evaluation of this pain should be with use of objective pain scales completed by the patient, not relying on physician impression. Treatment modalities available in the Emergency Department, a review of medications and their dosing as well as specifics to pediatric pain management are presented. The final section reviews situation or diagnosis specific pain control: headaches, renal colic, polytrauma victims, abdominal pain, soft tissue injury and acute arthritis. These recommendations are based on a Canadian Association of Emergency Physicians (CAEP) consensus conference held in April 1993. The literature was reviewed extensively and used as the basis for the consensus workshops and discussion. At the writing of the consensus paper, however, no specific ideas were borrowed from any one article. The appended bibliography is suggested reading, selected from the larger literature review. There are to date few controlled multi centre trials in overall pain management that would allow guidelines to be produced.

Emergency medicine and the public's health: emerging infectious diseases.

In recent years, multiple global forces have contributed to the emergence and widespread distribution of previously unknown disease entities. This article discusses Ebola virus, West Nile virus, and Hantavirus as representative emerging infectious diseases. Smallpox is discussed along with concerns about the safety of the smallpox vaccine, given the uncertain risk of bioterrorism and smallpox exposure. ED physicians must become familiar with the presentation, management, and public health impact of all of these entities, as well as understand the potential impact of other emerging infectious diseases.

The "ouchless emergency department". Getting closer: advances in decreasing distress during painful procedures in the emergency department.

Painful and frightening injuries and illnesses are frequent reasons for children to seek care in an emergency department. Painful therapeutic procedures are often a necessary part of emergency care and are very distressful for the children, their parents, and healthcare providers. Inadequately relieved pain and distress have acute and long-term consequences, yet methods for pain and anxiety reduction during frightening minor and major procedures are often not used because of lack of detailed knowledge of techniques and fear of adverse effects. This article reviews psychologic and pharmacologic means of safe and effective reduction of anxiety and pain during emergency department procedures.

Emergency intubation of the pediatric medical patient: use of anesthetic agents in the emergency department.

STUDY OBJECTIVES: To delineate the diagnoses of children who required emergency intubation, to ascertain which medications were used, and to describe the complications of intubation and their association with the choice of medications. DESIGN, SETTING, AND TYPE OF PARTICIPANTS: Three-year retrospective study of 60 intubations of critically ill pediatric patients by pediatric emergency physicians in the emergency department setting. MEASUREMENTS AND MAIN RESULTS: Clinical complications were noted for intubations with neuromuscular paralysis and intubations initially attempted without a paralyzing agent. Intubations attempted without neuromuscular paralysis resulted in a higher rate of complications (53% versus 26%) and a greater risk of more than one complication per intubation. This finding appeared to be independent of physicians' clinical experience. CONCLUSION: Rapid-sequence protocols with paralysis facilitate intubations in the complex pediatric patient in the ED setting.

Emergency medicine credentials in St Louis and Kansas City: does the presence of an emergency medicine residency program have a geographic difference?

STUDY OBJECTIVE: To compare emergency physician (EP) credentialing characteristics in two metropolitan areas of Missouri: Kansas City, which has had an emergency medicine (EM) residency program since 1973, and St Louis, which is without a program approved by the Accreditation Council for Graduate Medical Education. METHODS: A cross-sectional, descriptive survey concerning EP training, certification, and practice characteristics was administered by standardized telephone interviews. Participants were all emergency department directors in Kansas City and St Louis general hospital EDs serving more than 10,000 patients annually. RESULTS: Twenty Kansas City EDs, with an annual census of 20,250 +/- 7,200; and 30 St Louis EDs, with an annual census of 27,100 +/- 13,800, were surveyed. In Kansas City, 68% of practicing EPs were EM trained, versus 10% in St. Louis (P < .0005). The percentage of board-certified EPs was also greater in Kansas City than in St Louis (82% versus 42%, P < .0005). Eighty-six percent of ED directors in St Louis, compared with 30% in Kansas City, reported that they did not attempt to recruit EM-trained staff or that recruitment was difficult (P < .0005). CONCLUSION: The presence of an EM residency training program is associated with favorable EP credentialing characteristics in the Kansas City metropolitan area. This information may prove useful to institutions attempting to establish EM training programs in areas where none currently exist.

Effect of emergency physician-performed pelvic sonography on length of stay in the emergency department.

STUDY OBJECTIVE: To evaluate the sensitivity and specificity of emergency physician-performed pelvic sonography (EPPPS) and its effect on length of stay (LOS) in the emergency department. METHODS: The study involved a prospective observational convenience sample of women in early pregnancy requiring ED pelvic ultrasound evaluation. Differences in LOS were analyzed with the use of the Mann-Whitney test, with EPPPS and consultation status as classification variables. Results were stratified by diagnosis to identify patient subsets in which EPPPS had the greatest impact. A multivariate model was used to determine the independent associations of EPPPS and consultation status with LOS. RESULTS: Among 115 pregnant patients, those who underwent EPPPS had a decreased median LOS compared with those who received pelvic sonography administered by radiologists or obstetrics-gynecology consultants (60 versus 180 minutes; P < .001). Obstetrics-gynecology consultation was associated with an increase in LOS from 60 to 170 minutes (P < .001). Stratification revealed that the decreased LOS was most significant in patients with viable intrauterine pregnancies (IUPs) and was not seen in those with abnormal pregnancies. This result was attributed primarily to the need for consultation in the latter group. Multivariate analysis demonstrated that EPPPS remained significantly associated with decreased LOS overall, after adjustment for the potentially confounding effect of consultation status (P < 001). The sensitivity of EPPPS for IUP was 94% (95% confidence interval [CI], 82% to 98%), and the specificity was 100% (95% CI, 83% to 100%). All 10 ectopic pregnancies, six of which were detected by EPPS and are included in the aforementioned sensitivity and specificity analysis, plus four detected by NEPPPS, were correctly identified; none was missed. No patient had an adverse outcome as a result of EPPPS. CONCLUSION: Pelvic ultrasound performed by emergency physicians after a brief period of training shortens ED LOS in women in early pregnancy, particularly in those with viable IUPs. This practice appears to be sensitive, specific, and safe.

Mass-casualty, terrorist bombings: implications for emergency department and hospital emergency response (Part II).

This article reviews the implications of mass-casualty, terrorist bombings for emergency department (ED) and hospital emergency responses. Several practical issues are considered, including the performance of a preliminary needs assessment, the mobilization of human and material resources, the use of personal protective equipment, the organization and performance of triage, the management of explosion-specific injuries, the organization of patient flow through the ED, and the efficient determination of patient disposition. As long as terrorists use explosions to achieve their goals, mass-casualty, terrorist bombings remain a required focus for hospital emergency planning and preparedness.

The emergency nurse practitioner role in major accident and emergency departments: professional issues and the research agenda.

The emergency nurse practitioner (ENP) is a rapidly developing role within emergency health care provision in the United Kingdom (UK). This paper explores some of the available literature concerning the development of the role in the context of major accident and emergency departments. The professional and legal implications of this shift in role boundaries are discussed. The current inconsistencies in educational provision and the potential consequences for practice in this area, are highlighted. The relative plethora of rigorous evaluation studies of ENP role effectiveness in North America, is contrasted with the current paucity of empirical data available in the UK. A number of methodological issues concerning the evaluation of ENP services are identified. The need for research in this area, alongside a programme of continuing local audit to guide and inform evidence-based practice, is emphasized.

Methods of categorizing emergency department visit urgency: a survey of pediatric emergency medicine physicians.

OBJECTIVE: Between 20% and 80% of emergency department (ED) visits are nonurgent. This variability in estimates is partially due to the multiple classification methods used, none of which has undergone validity or reliability testing. Our objectives were to determine the methods thought to be most valid and to understand expert perceptions of nonurgent ED utilization. METHODS: A survey of the Pediatric Emergency Medicine (PEM) Special Interest Group at the 2005 Pediatric Academic Societies meeting was conducted. An education session with case-based discussion for categorizing ED visit urgency was presented. Six methods were reviewed: implicit criteria, explicit criteria, resource utilization, diagnoses, Current Procedural Terminology Codes, and nurse triage category. The primary outcome was the percentage of respondents ranking each method first or second best for categorizing urgency. Respondents also identified ED resources and presenting symptoms constituting an urgent visit. RESULTS: Seventy-four percent of attendees completed the survey, most were Pediatric Emergency Medicine physicians. Implicit criteria were rated highest, with 65.1% ranking it first or second, followed by explicit criteria (53.8%). With limited data available, resource utilization ranked highest (68.6%), followed by nurse triage (61.2%). There was an agreement that certain presenting symptoms and resources were adequate for determining ED visit urgency; however, there was no agreement on whether x-rays, urinalyses, or fever in a child older than 3 months was sufficient to identify urgency. CONCLUSIONS: Methods using complete medical record information are favored to determine ED visit urgency. Resource utilization and nurse triage are preferred when limited data are available. This survey will serve as the basis for endorsement of methodologically sound criteria for ED visit urgency.

Mortality of blunt polytrauma: a comparison between emergency physicians and emergency medical technicians--prospective cohort study at a level I hospital in eastern Switzerland.

BACKGROUND: The role of prehospital basic life support as opposed to prehospital advanced life support and the best qualifications for emergency personnel are controversial. Our objective was to establish whether the prehospital deployment of emergency physicians (EPs) rather than emergency medical technicians (EMTs) decreased mortality in blunt polytrauma patients. METHODS: In a prospective, observational cohort study conducted between 1990 and 1996, we used the A Severity Characterization of Trauma score to compare the actual mortality with the predicted mortality in 71 blunt polytrauma patients, 63 treated by EMTs alone and 8 treated also by anesthetic nurses. The same comparison was conducted in 196 blunt polytrauma patients treated by EPs together with EMTs or paramedics. Multivariate logistic regression analysis was conducted to test for any confounding factors and bias, and for the identification of factors associated with mortality. Inclusion criteria were blunt trauma at a minimum of two body sites, an Injury Severity Score of 8 or more, and direct admission to our trauma center. RESULTS: The mortality in patients treated by EPs was 11.2% (22 of 196) and was statistically not significantly lower than the 14.1% calculated for the patients treated without EP involvement (10 of 71). In the group treated by EPs, there were 1.3 (95% confidence interval [CI], -5.9-8.5), or 6%, fewer deaths than would have been expected on the basis of the results of the Major Trauma Outcome Study (p = 0.734). In contrast, in the group treated without EP involvement, there were 3.4 (95% CI, -0.2-7), or 34%, more deaths than predicted (p = 0.066). This trend was confirmed by multivariate logistic regression, which showed a significant mortality odds ratio of 37 (95% CI, 2-749) for the EMT group as compared with the EP group. CONCLUSION: In contrast with the deployment of EPs, care of blunt polytrauma patients by EMTs showed a statistical trend to a higher mortality than predicted and also a significantly higher risk of mortality. It is likely that the consistent deployment of EPs for moderate to severe blunt polytrauma in our catchment area might prevent between 0% and 23% of all deaths from blunt polytrauma or, in absolute terms, up to 1 death per year or 0 to 9.9 per 100 patients treated by an EP instead of an EMT.

Doing unto others? Emergency medicine residents' willingness to be treated by moonlighting residents and nonphysician clinicians in the emergency department.

OBJECTIVE: Contentious moonlighting policies and the proliferation of nonphysician clinicians (NPCs) in academic emergency departments (EDs) send conflicting messages to emergency medicine (EM) residents regarding appropriate ED staffing patterns. The objective was to assess EM resident (EMR) views on the ED utilization of unsupervised residents and NPCs from their perspectives as both physicians and prospective patients. METHODS: A survey was mailed to a random sample of senior EMRs (sampling fraction, 68%) from the Emergency Medicine Residents Association membership list. Respondents were instructed to assume the role of patient when presented with hypothetical clinical scenarios of increasing severity; outcomes included provider preferences and the impacts of medical urgency, time delays, costs, and supervision on those preferences. Survey items asked about willingness to see residents, nurse practitioners (CRNPs), and physician assistants (PAs), and perceived impact of NPCs on professional identity. RESULTS: A total of 251 EMRs responded. Senior EMRs are more willing to have their care handled by residents as opposed to mid-level providers. For a moderate illness or injury scenario, 54% agreed to be seen by a resident alone compared with only 17% and 24% willing to be seen by a CRNP and PA, respectively. Only a small fraction of the residents (22.7%) would allow another resident to treat them for a major injury or illness. Residents are more willing to be seen by mid-level providers if a savings in time can be realized but showed little interest in using NPCs to save money. Approximately one-third (34%) of the residents view mid-level providers as a professional threat, but logistic regression reveals this perception to be 2.25 (1.3, 4.0) times higher in male EMRs and 1.94 (1.1, 3.4) times higher in those with higher household incomes (> or =$75,000). CONCLUSIONS: When assuming the patient role, senior EMRs have preferences for ED care that are consistent with restrictive EMR moonlighting and NPC staffing policies.

Comparison of the rapid emergency medicine score and APACHE II in nonsurgical emergency department patients.

OBJECTIVES: To improve the Rapid Acute Physiology Score (RAPS) as a predictor of in-hospital mortality in the nonsurgical emergency department (ED) by including age and oxygen saturation, and to compare this new system, Rapid Emergency Medicine Score (REMS), with the Acute Physiology and Chronic Health Examination (APACHE II) with reference to predictive accuracy. METHODS: This was a prospective cohort study. One hundred sixty-two critically ill patients consecutively admitted to the intensive care unit (ICU) during the period of one year, and 865 nonsurgical patients presenting to an adult emergency department (ED) and admitted to a medical department of a 1200-bed university hospital during two months, were enrolled. For all entries to the ED, RAPS was calculated and developed to include noninvasive peripheral oxygen saturation and patient age (REMS), as well as laboratory tests (APACHE II). These scores were calculated for each patient. RESULTS: REMS was found to be superior to RAPS in predicting in-hospital mortality both in the critically ill patients admitted to the ICU and in the total sample (area under receiver-operating characteristic curve [AUC] 0.910 +/- 0.015 for REMS compared with 0.872 +/- 0.022 for RAPS, p < 0.001). An increase of 1 point in the 26-point REMS scale was associated with an odds ratio of 1.40 for in-hospital death (95% confidence interval = 1.36 to 1.45, p < 0.0001). The more advanced APACHE II was not found to be superior to REMS (AUC: 0.901 +/- 0.015, p = 0.218). CONCLUSIONS: RAPS could be improved as a predictor of in-hospital mortality in the nonsurgical ED by including oxygen saturation and patient age to the system. This new scoring system, REMS, had the same predictive accuracy as the well-established, but more complicated, APACHE II.

Preventive care in the emergency department: screening for domestic violence in the emergency department.

OBJECTIVES: The most effective methods for identification and management of domestic violence (DV) victims in health care settings are unknown. The objective of this study was to systematically review screening for DV in the emergency department (ED) to identify victims and decrease morbidity and mortality from DV. METHODS: Using the terms "domestic violence" or "partner violence," and "identification" or "screening," and "emergency," the authors searched MEDLINE, the Cochrane Database, and Emergency Medical Abstracts from 1980-2002. They selected articles studying screening tools, interventions, or determining the incidence or prevalence of DV among ED patients. The studies were analyzed using evidence-based methodology. RESULTS: Three hundred thirty-nine articles resulted from the literature search. Based on selection criteria, 45 were reviewed in detail and 17 pertained to the ED. From references of these 17 articles, three additional articles were added. Screening can be conducted using a brief verbal screen and existing ED personnel. A randomized, controlled trial did not demonstrate a difference in screening rates between experimental and control hospitals. No studies assessed the effect of ED screening for DV on morbidity or mortality of domestic violence. An ED-based advocacy program resulted in increased use of shelters and counseling. CONCLUSIONS: Because of the paucity of outcomes research evaluating ED screening and interventions, there is insufficient evidence for or against DV screening in the ED. However, because of the high burden of suffering caused by DV, health care providers should strongly consider routinely inquiring about DV as part of the history, at a minimum for all female adolescent and adult patients.

A prospective survey of hospital ambulatory dental emergencies. Part 1: Patient and emergency characteristics.

Part 1 of this study describes the dental disorders and patient characteristics of 253 patients who presented as dental emergencies to the University Hospital dental clinic, Vancouver, BC, during a three-month period. Most patients had a true perception of what constitutes a dental emergency. Dental pain was the predominant reason for seeking help, and the pain existed for more than seven days prior to contact in more than 50% of patients. Patients were not always able to identify the number and location of painful teeth, and a perceived low cost for treatment was a major reason for contacting the hospital. Reliability of emergency patients in keeping scheduled appointments was very high. Almost 69% of patients did not see a dentist regularly. Referrals to the hospital dental service were most numerous in the summer months. Diagnosis of the complaints revealed infection to be the cause of pain in 76.7% of patients.
