The influence of the mode of emergency ambulance transportation on the emergency patient's outcome.

Emergency transport by an ambulance can cause considerable psychical and physical stress for patients. We determined the haemodynamic and endocrinological values of 54 healthy volunteers subjected to one high speed emergency transport and one smooth transport. There were significant differences in all measurements: heart rate (p < or = 0.001), blood pressure, cortisol (p < or = 0.01), prolactin, somatotropine and ACTH between the two modes of transportation. We hypothesize that the additional stress of high speed ambulance transport particularly in patients with acute cardiac disease may result in additional morbidity.

Rapid Emergency Medicine score: a new prognostic tool for in-hospital mortality in nonsurgical emergency department patients.

OBJECTIVES: To evaluate the predictive accuracy of the scoring system Rapid Acute Physiology score (RAPS) in nonsurgical patients attending the emergency department (ED) regarding in-hospital mortality and length of stay in hospital (LOS), and to investigate whether the predictive ability of RAPS could be improved by extending the system. DESIGN: Prospective cohort study. SETTING: An adult ED of a 1200-bed university hospital. SUBJECTS: A total of 12 006 nonsurgical patients presenting to the ED during 12 consecutive months. METHODS: For all entries to the ED, RAPS (including blood pressure, respiratory rate, pulse rate and Glasgow coma scale) was calculated. The RAPS system was extended by including the peripheral oxygen saturation and patient age (Rapid Emergency Medicine score, REMS) and this new score was calculated for each patient. The statistical associations between the two scoring systems and in-hospital mortality as well as LOS in hospital were examined. RESULTS: The REMS was superior to RAPS in predicting in-hospital mortality [area under receiver operating characteristic (ROC) curve 0.852 +/- 0.014 SEM for REMS compared with 0.652 +/- 0.019 for RAPS, P < 0.05]. An increase of 1-point in the 26-point REMS scale was associated with an OR of 1.40 for in-hospital death (95% CI: 1.36-1.45, P < 0.0001). Similar results were obtained in the major patient groups (chest pain, stroke, coma, dyspnoea and diabetes), in all age groups and in both sexes. The association between REMS and LOS was modest (r = 0.47, P = 0.0001). CONCLUSIONS: The REMS was a powerful predictor of in-hospital mortality in patients attending the ED over a wide range of common nonsurgical disorders.

Emergency department do-not-attempt-resuscitation orders: next-of-kin response to the emergency physician.

OBJECTIVE: To evaluate the response by families of incompetent, chronically debilitated, and/or terminally ill patients who were contacted for do-not-attempt-resuscitation (DNAR) status by an emergency physician (EP). METHODS: A prospective observational study was performed to assess next-of-kin willingness to support DNAR status for incompetent, chronically debilitated, and/or terminally ill patients. The families also were contacted by telephone follow-up 48-72 hours after the ED visit. Upon follow-up evaluation, the families were surveyed regarding prior DNAR instructions and their perceptions of the establishment of DNAR status in the ED. The study was conducted in an urban teaching hospital with an emergency medicine residency training program. RESULTS: Of the 71 patient families contacted, 60 (85%) of the patients had DNAR orders written in the ED. The families of these 60 patients had no negative response regarding contact by ED personnel. Of the 11 (15%) patients whose families wished no DNAR order, only two families had negative responses to being contacted by the EP. In both cases the families had previously given detailed instructions to the chronic care facility. CONCLUSION: The EP can play an important role in assisting the decision making process of families of incompetent, chronically debilitated, and/or terminally ill patients regarding institution of DNAR orders in the ED. Improved communication regarding existing DNAR orders with chronic care facilities might minimize the rare complaints received from families with preestablished DNAR orders.

Emergency medicine in undergraduate education. SAEM Education Committee, Undergraduate Subcommittee, Society for Academic Emergency Medicine.

Society has a right to expect that all physicians possess basic knowledge of emergency care and the skills to manage acute problems. Competency in the care of acutely ill and injured patients is one of the fundamental exit goals of most medical schools as mandated by the Liaison Committee on Medical Education. Several groups have called for strengthening the general components of undergraduate medical education, and surveys during the early years of the development of the field of emergency medicine (EM) showed that only a small percentage of schools required significant education in EM. This paper defines the goals and objectives of undergraduate EM education in order to help guide the development of curricular offerings as the role of EM in undergraduate medical school education increases. This paper was developed by the SAEM Education Committee and presents this committee's beliefs on what all graduating medical students should know about assessment and treatment of acutely sick and injured patients. It also suggests methods by which acquisition of this information can occur in medical school education.

Should parents be present during emergency department procedures on children, and who should make that decision? A survey of emergency physician and nurse attitudes.

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.

Preventive care in the emergency department: should emergency departments conduct routine HIV screening? a systematic review.

OBJECTIVE: To perform a systematic review of the emergency medicine literature to assess the appropriateness of offering routine HIV screening to patients in the emergency department (ED). METHODS: The systematic review was conducted with the aid of a structured template, a companion explanatory guide, and a grading and methodological scoring system based on published criteria for critical appraisal. Two reviewers conducted independent searches using OvidR, PubMed, MD Consult, and Grateful Med. Relevant abstracts were reviewed; those most pertinent to the stated objective were selected for complete evaluation using the structured template. RESULTS: Fifty-two relevant abstracts were reviewed; of these, nine were selected for detailed evaluation. Seven ED-based prospective cross-sectional seroprevalence studies found HIV rates of 2-17%. Highest rates of infection were seen among patients with behavioral risks such as male homosexual activity and intravenous drug use. Two studies demonstrated feasibility of both standard and rapid HIV testing in the ED, with more than half of the patients approached consenting to testing by either method, consistent with voluntary testing acceptance rates described in other settings. Several cost-benefit analyses lend indirect support for HIV screening in the ED. CONCLUSIONS: Multiple ED-based studies meeting the Centers for Disease Control and Prevention Guideline threshold to recommend routine screening, in conjunction with limited feasibility trials and extrapolation from cost-benefit studies, provide evidence to recommend that EDs offer HIV screening to high-risk patients (i.e., those with identifiable risk factors) or high-risk populations (i.e., those where HIV seroprevelance is at least 1%).

Primary care patients in the emergency department: who are they? A review of the definition of the 'primary care patient' in the emergency department.

OBJECTIVE: To review the definition of 'primary care' and 'inappropriate' patients in ED and develop a generally acceptable working definition of a 'primary care' presentation in ED. METHOD: A Medline review of articles on primary care in ED and the definitions used. RESULTS: A total of 34 reviewed papers contained a proposed definition or comment on the definition for potential 'primary care', 'general practice', or 'inappropriate' patients in ED. A representative definition was developed premised on the common factors in these papers: low urgency/acuity--triage categories four or five in the Australasian Triage Scale, self-referred--by definition, patients referred by general practitioner/community primary medical services are not primary care cases because a primary care service has referred them on, presenting for a new episode of care (i.e. not a planned return because planned returns are not self-referred), unlikely to be admitted (in the opinion of Emergency Nurse interviewers) or ultimately not admitted. DISCUSSION: This definition can be applied either prospectively or retrospectively, depending on the purpose. Appropriateness must be considered in light of a legitimate role for ED in primary care and the balance of resources between primary care and emergency medicine in local settings.

Expected annual emergency miles per ambulance: an indicator for measuring availability of Emergency Medical Services resources.

CONTEXT: To ensure equitable access to prehospital care, as recommended by the Rural and Frontier Emergency Medical Services (EMS) Agenda for the Future, policymakers will need a uniform measure of EMS infrastructure. PURPOSE AND METHODS: This paper proposes a county-level indicator of EMS resource availability that takes into consideration existing EMS resources (ambulances), population health and demographics, and geographic factors. The indicator, the EXpected annual emergency miles per AMBulance (EXAMB), provides a basis for comparing ambulance availability across counties within states. A method for calculating the EXAMB indicator is demonstrated using data from 5 states. FINDINGS: The EXAMB indicator was negatively correlated with ambulance availability per 100,000 population in 4 of the 5 states in the study. The indicator was positively correlated with rurality in 3 states. In Mississippi, South Carolina, and Wyoming, whole-county health professional shortage areas had median EXAMB values 45%-81% higher than those of the non-health professional shortage areas counties. CONCLUSIONS: Future research should explore the relationship of the EXAMB to EMS outcomes, with the ultimate goal of developing a nationally recognized indicator of "adequate" EMS resource availability.

A prospective survey of hospital ambulatory dental emergencies. Part 2: Follow-up to emergency treatment.

Two hundred and fifty-three patients treated for dental emergencies at the University Hospital dental clinic over a three-month period were surveyed by telephone 24 to 48 hours and one year after treatment. The purpose was to investigate the success of treatment in resolving the chief complaint of pain and to determine the compliance with further dental care for the original dental problem. The results of the telephone survey showed that: patients available for questioning totaled 49.1% at 24 to 48 hours and 28.9% at one year; an 80.7% success rate was recorded in resolving pain within 24 to 48 hours; and the original emergency problem did not motivate a large number of these patients to seek further dental care.

Teaching in accident and emergency medicine: 10 commandments of accident and emergency radiology.

One of the many attractions of accident and emergency medicine is the wide and varied opportunities it provides for education. This is because of the acute nature of the work, which necessitates prompt and accurate decision making. However, in many instances the decisions have to be made by inexperienced senior house officers. Departments therefore need a safe system of practice that can be remembered and adhered to under stress. The 10 commandments is one such system for analysing emergency radiographs of all the regions of the body. This system lays down guidelines to protect both staff and hospitals from the inevitable mistakes that inexperienced doctors will make.

Non-emergency attenders at a district general hospital accident and emergency department.

Following concern about long waiting times, a survey was carried out in the Accident and Emergency (A&E) department of Monklands District General Hospital over 5 consecutive days to investigate factors related to the bypassing of general practitioners (GPs) by 'self-referred' patients and inappropriate use of the department. Two hundred and forty-five (90.7%) of 270 non-emergency patients who attended the department during GP surgery hours completed a self-administered questionnaire. Variables measured included recent use of health services, perceptions of the GP service and the A&E service and reasons for bypassing the GP. Of the 245 patients, 49 (20%) were defined as inappropriate and 152 (62%) were self-referred. Self-referred patients were no more likely to use the A&E department inappropriately than those who were referred.

Towards evidence-based emergency medicine: best BETs from the Manchester Royal Infirmary. Accuracy of emergency department ultrasound scanning in detecting abdominal aortic aneurysm.

A short-cut review was carried out to establish whether emergency department ultrasound scanning had clinical utility for the diagnosis of abdominal aortic aneurysm (AAA). A total of 73 papers were found using the reported searches, of which 4 presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated. It is concluded that in patients suspected of having AAA, emergency department bedside ultrasound scanning for AAA is sensitive and specific and may improve patient care.

The use and abuse of the emergency ambulance service: some of the factors affecting the decision whether to call an emergency ambulance.

Over a 1-month period all patients arriving in the accident and emergency department by ambulance following a '999' call were questioned using a standard proforma. They were assessed as to whether their medical condition warranted ambulance transfer. A number of social and practical points were analyzed to see whether they would identify any group of patients who used the emergency service without medical need. Overall 289 patients were questioned. Of these 178 (62%) were considered to have medically warranted an ambulance call whereas 111 (38%) did not. A number of features which were more likely to result in an unjustified call were identified. These would suggest that basic knowledge of first aid by the public is poor and should be improved.

Antiemetic use in pediatric gastroenteritis: a national survey of emergency physicians, pediatricians, and pediatric emergency physicians.

The objective of this study was to review the use of antiemetics for pediatric gastroenteritis and to determine prescribing patterns of physicians. A mailed cross-sectional survey instrument was sent to randomly selected board-certified emergency medicine, pediatric, and pediatric emergency medicine specialists. A total of 1665 surveys were mailed, with 593 completed surveys returned (35.6% response rate). A majority of responders (60.9%) reported using antiemetics for pediatric gastroenteritis at least once in the past year, with a greater than 50% usage for all three specialty groups. Promethazine was the most commonly used antiemetic in all specialties, and per rectum the most common route of administration. Adverse reactions following a single dose of antiemetic were most frequently reported with prochlorperazine. The most common reason for antiemetic use was to prevent further dehydration. The most common concern regarding antiemetic use was potential for side effects. Occasional antiemetic use appears to be a common practice in treating pediatric gastroenteritis, regardless of specialty. Given the absence of literature on efficacy or safety, these drugs should be used only with careful consideration to potential side effects.

Emerging and re-emerging diseases in Malaysia.

Emerging and re-emerging infectious diseases have become a major global problem. Malaysia appears to be an epicenter for such infections and in recent years, several outbreaks have occurred resulting in loss of lives and economic hardships. In this paper, we discussed the outbreaks of leptospirosis, enterovirus 71 encephalitis, chikungunya polyarthritis and Nipah encephalitis and how a developing country such as Malaysia managed the situation with the help of international agencies and organisations. Many valuable lessons were learned and by sharing our experience, it is hoped that we will be in a better position to handle future outbreaks and prevent their spread to countries in the region.

Adequacy of medical chart review to characterize emergency care for asthma: findings from the Illinois Emergency Department Asthma Collaborative.

OBJECTIVES: To assess the intermethod reliability of medical chart review compared with directly observed care in patients presenting to emergency departments (EDs) for asthma care. METHODS: ED care practices for persons with asthma were evaluated by comparing chart review with trained observers. Fifty-one patients from five EDs participating in the Illinois Emergency Department Asthma Collaborative were studied. Practices in assessment, treatment, education, and referral were measured. Eighteen elements of care were assessed. Concordance between chart and observation was measured by using the kappa statistic. RESULTS: Of 51 subjects studied, nine were children. Kappa values varied depending on content. Kappa values ranged from 0.22 to 0.91 for items reflecting asthma assessment. Good concordances (kappa = 0.50 to 0.82) were found for items reflecting treatment practices. The lowest concordances were for items assessing educational activities (kappa = 0.04 to 0.34). Referral practices had fair to moderate concordances (kappa = 0.21 to 0.45). CONCLUSIONS: Intermethod reliability of medical chart review and directly observed care varied depending on the element of care being measured. The use of chart review to measure quality of ED-based asthma care may only be appropriate for a limited number of care processes that are reliably and validly captured from chart review.

The effect of alcohol consumption on emergency department services use among injured patients: A cross-national emergency room study.

OBJECTIVE: Although injured patients in the emergency department (ED) report more frequent use of the ED compared with the general population, and alcohol-related admissions and chronic alcohol misuse have been found to be predictive of future ED admissions, these data are based on only a few U.S. studies. The purpose of this article was to explore the association of alcohol use and ED services use among injured patients cross-nationally. METHOD: Binary and multinomial logistic regression were used to analyze the association of alcohol consumption with prior ED visits among 9,743 injured patients surveyed in 37 EDs in 14 countries and reported in 23 studies from the combined Emergency Room Collaborative Alcohol Analysis Project (ERCAAP) and World Health Organization Collaborative Study of Alcohol and Injuries. RESULTS: Drinking within 6 hours before injury was associated with prior ED visits during the last 12 months (odds ratio = 1.25, p < .05), with a positive dose-response relationship. Heavy drinkers and those drinkers who were alcohol-dependent were also significantly more likely to report multiple prior ED visits, reflecting an elevated burden of services use. At the ED level, stigmatization of alcohol use was the only significant contextual variable that consistently predicted cross-ED variation in the relationship between drinking and ED use, in which the association was weaker in areas where alcohol use is less accepted. CONCLUSIONS: This study lends additional support to the potential effectiveness of screening for acute and chronic alcohol use among ED injured patients to reduce ED services use and associated costs.
