Systematic triage in the emergency department using the Australian National Triage Scale: a pilot project.

The objective of this study was to evaluate the validity in Belgium of the National Triage Scale for judgement of the urgency of a patient's condition and making a case-mix description of the patient profiles in the different urgency categories. The study is of a descriptive retrospective and descriptive correlational design and was carried out in the emergency department at the University Hospital Gasthuisberg in Leuven, Belgium. The urgency of patients arriving at the emergency department was evaluated during one randomly selected shift a day over 12 weeks in 1997 by one of the four triage-educated nurses, using an instrument based on the National Triage Scale. Patient identification and outcome parameters were retrieved from the existing computer system. The data were mainly analysed using the Ridit analysis. Overall 3650 patients were evaluated: Category 1, 4.19%; Category 2, 24.44%; Category 3, 39.32%; Category 4, 27.97%; Category 5, 4.08%. Any similarity between sentinel diagnoses as well as between the admission percentages in this pilot study and the reference from Australia (Z = 0.827; p > 0.05) was noted. Different aspects influenced the triage nurses while determining the degree of urgency. Urgency categories profiles revealed a significant effect of age (Kruskall-Wallis = 530.5; p = 0.000). Higher categories of urgency resulted in a higher degree of admission (t (df = 3640) = 643.45; p = 0.000). It is concluded that a resemblance between the pilot study and the reference confirms the predictive validity of the scale used. Patient profiles in the different urgency categories give a description of the emergency department population.

"Recommendations for uniform reporting of data following major trauma--the Utstein style" (as of July 17, 1999). An International Trauma Anaesthesia and Critical Care Society (ITACCS).

Basic and advanced care of trauma patients has always been an important aspect of prehospital and immediate in-hospital emergency medicine, involving a broad spectrum of disciplines, specialties and skills delivered through Emergency Medical Services Systems which, however, may differ significantly in structure, resources and operation. This complex background has, at least in part, hindered the development of a uniform pattern or set of criteria and definitions. This in turn has hitherto rendered data incompatible, with the consequence that such differing systems or protocols of care cannot be readily evaluated or compared with acceptable validity. Guided by previous consensus processes evolved by the ERC, the AHA and other International Organizations--represented in ILCOR--on 'Uniform reporting of data following out-of-hospital and in-hospital cardiac arrest--the Utstein style' an international working group of ITACCS has drafted a document, 'Recommendations for uniform reporting of data following major trauma--the Utstein style'. The reporting system is based on the following considerations: A structured reporting system based on an "Utstein style template" which would permit the compilation of data and statistics on major trauma care, facilitating and validating independent or comparative audit of performance and quality of care (and enable groups to challenge performance statistics which did not take account of all relevant information). The recommendations and template should encompass both out-of-hospital and in-hospital trauma care. The recommendations and template should further permit intra- and inter-system evaluation to improve the quality of delivered care and identification of the relative benefits of different systems and innovative initiatives. The template should facilitate studies setting out to improve epidemiological understanding of trauma; for example such studies might focus on the factors that determine survival. The document is structured along the lines of the original Utstein Style Guidelines publication on 'prehospital cardiac arrest'. It includes a glossary of terms used in the prehospital and early hospital phase and definitions, time points and intervals. The document uses an almost identical scheme for illustrating the different process time clocks--one for the patient, one for the dispatch centre, one for the ambulance and, finally, one for the hospital. For clarity, data should be reported as core data (i.e. always obtained) and optional data (obtained under specific circumstances). In contrast to the graphic approach used for the Utstein template for pre- or in-hospital cardiac arrest, respectively, the present template introduces, for the time being, at least, a number of terms and definitions and a semantic rather than a graphic report form. The document includes the following sections: The Section Introduction and background The Section on Trauma Data Structure Development: presents a general outline of the development of structured data using object-orientated modelling (which will be discussed in due course) and includes a set of explanatory illustrations. The Section on Terms and Definitions: outlines terms and definitions in trauma care, describing different types of trauma (blunt, penetrating, long bone, major/combined, multiple/polytrauma and predominant trauma). The Section on Factors relating to the circumstances of the injury describes the following items: cause of injury (e.g. type of injury (blunt or penetrating), burns, cold, crush, laceration, amputation, radiation, multiple, etc. Severity of Injury e.g. prehospital basic abbreviated injury score developed by the working group. The score contains anatomical and physiological disability data, with the anatomical scale ranging ordinally from 1. Head to 9. External; the physiological disability scale ranging ordinally from 0--unsurvivable. Mechanism of injury recording for transportation incidents etc. e.g. the type of impact, po

Prospective use of glycoprotein IIb/IIIa receptor blockers in the emergency department setting.

Platelets play a pivotal role in the pathophysiology of acute coronary syndromes (ACS) and thus are logical therapeutic targets for treatment of this disease process. Platelet glycoprotein (GP) IIb/IIIa receptor antagonists, which interrupt the final common pathway of platelet aggregation, have been proved to reduce the 30-day incidence of death, acute myocardial infarction (MI), and urgent revascularization in both high-risk and low-risk patients undergoing percutaneous intervention procedures. Three-year follow-up has indicated that these benefits appear durable. Recent large-scale randomized trials have demonstrated the value of GP IIb/IIIa receptor inhibitors in reducing the risk of death and MI in patients with unstable angina or those with MI with non-Q-wave abnormalities who are receiving pharmacologic management. In addition, emerging evidence suggests a future role for GP IIb/IIIa receptor inhibitors as an adjunct to low-dose fibrinolytic therapy in patients with acute MI. As the list of indications for GP IIb/IIIa receptor antagonists expands to encompass the full spectrum of ACS, there is increasing interest in the potential use of these agents in the emergency department setting. The integration of GP IIb/IIIa receptor inhibitors into ED protocols will ultimately depend largely on whether these drugs prove to be safe and effective regardless of the direction of ST-segment deviation, and irrespective of whether definitive therapy will be invasive or conservative.

Emergency department walk-in patients study.

We conducted a 25-week study of the emergency department's (ED) walk-in patients at a university hospital, covering 20% of the total period by a Latin square method of 6-h blocks. One thousand eight hundred walk-in patients entered the study group. The walk-in population represents approximately 44% of the total ED population. Our results reveal that the study population was predominantly male, aged less than 40 years but somewhat younger than the general population and had a relatively stable place of abode. Trauma and medical patients were respectively 46% and 53%. Eight-six per cent of the trauma patients came to the ED on their own initiative and less than 3 h after the accident or injury, while 43% of the medical patients were referred by a medical practitioner and had a relatively longer duration of symptoms. Forty-eight per cent of the medical patients visited the ED 12 h after the onset of symptoms. Although this study only concerned ED walk-in patients, the admission rate of medical patients is relatively high: 47% as opposed to the trauma patients' 10%. About 10% of the walk-in patients were classified as 'symptoms, signs and ill-defined conditions' according to the International Classification of Diseases 9. Fifty-two per cent of these patients were discharged home. This group of patients requires further investigation.

Quality and efficiency of bystander CPR. Belgian Cerebral Resuscitation Study Group.

Incorrectly performed bystander CPR might compromise survival of the cardiac arrest patient. We therefore evaluated the outcome in 3306 out-of-hospital primary cardiac arrests of which 885 received bystander CPR. bystanders performed CPR correctly in 52%, incorrectly in 11%, 31% performed only external chest compressions (ECC) and 6% only mouth-to-mouth ventilation (MMV). The initial ECG in cases without bystander CPR was ventricular fibrillation in 28% (95% confidence interval: 27-30%); 45% (41-50%) and 39% (29-48%), respectively when bystander CPR was performed correctly or incorrectly; 43% (37-49%) when only ECC was applied and 22% (11-33%) when only MMV was practiced. Long term survival, defined as being awake 14 days after CPR, was 16% (13-19%) in patients with correct bystander CPR; 10% (7-14%) and 2% (0-9%), respectively when only ECC or only MMV was performed; 7% (6-8%) when no bystander was involved; 4% (0-8%) when bystander CPR was performed incorrectly. Bystander CPR might have a beneficial effect on survival by maintaining the heart in ventricular fibrillation by ECC. A negative effect of badly performed bystander CPR was not observed compared to cases which had not received bystander CPR.

Should semi-automatic defibrillators be used by emergency medical technicians in Belgium? The Belgian Cerebral Resuscitation Study Group.

Early external defibrillation is the single most effective intervention in patients with out-of-hospital cardiac arrest. Literature data indicate that instructing emergency medical technicians (EMTs) to use defibrillators is beneficial, provided the local emergency medical system is well organized. We tried to estimate the potential benefit of early defibrillation in some centres in Belgium by retrospectively analyzing the data from the Belgian Cardio-Pulmonary-Cerebral Resuscitation Registry collected between 1983 and 1987 in Belgian centres with a Mobile Intensive Care Unit (MICU). The data show that 2310 out of 3371 patients (69%) were first attended by the EMTs; on subsequent arrival of the MICU-teams, 584 of these 2310 patients i.e. 17% of the whole study population, presented with ventricular fibrillation. Analysis of estimated time factors in these 2310 patients revealed that the median time interval between collapse and start of resuscitation by EMTs was 8 min; the median time interval between collapse and start of MICU-resuscitation attempts was 16 min. The duration of EMT-resuscitation before MICU-arrival was probably more than 5 min and 10 min in 58% and 23% of the cases respectively. It is concluded that EMTs can be expected to reach a substantial number of ventricular fibrillation victims within a few minutes after the collapse and many minutes before arrival of the MICU. Therefore, training of EMTs in the use of semi-automatic defibrillators seems worthwhile in MICU-served regions in Belgium.

Gastrointestinal decontamination for acute poisoning.

Acute poisoning remains a common cause of morbidity and even mortality in children and adults. The goal of gastrointestinal decontamination is to eliminate or to reduce the potentially life-threatening effects of the ingested poison. Methods of gastrointestinal detoxication in case of acute poisoning, such as induced emesis, gastric lavage, administration of activated charcoal and intestinal cleansing are discussed. As far as induced emesis is still concerned, only the administration of Ipecac-syrup can be retained. The controversy between emesis and gastric lavage still remains. For those toxins well adsorbed by activated charcoal, the administration of activated charcoal, followed or not by gastric lavage, is the treatment of choice. Single doses of activated charcoal can be insufficient. In certain kinds of poisoning, repeated doses of activated charcoal are advisable because of the interruption of the entero-hepatic and entero-enteric circulation. The benefit and the indications for intestinal cleansing in case of acute poisoning seem to be very limited.

Weather influence on the prevalence of carbon monoxide intoxications.

In a retrospective study over 7 years, data from patients admitted to the Emergency Department with CO intoxication, together with meteorological data were analysed. A statistically significant difference in weather conditions was noticed between CO-intoxication days and reference days. Different weather conditions were found to be present, according to the source of CO, i.e. gas boiler or coal stove. If these data are confirmed, a major role in the prevention of CO intoxication or its sequellae can be played by the media through weather broadcasting. Warning can raise the index of suspicion of physicians and warn the population for vague, collectively appearing sensations of ill feeling.

Predictive value of Glasgow coma score for awakening after out-of-hospital cardiac arrest. Cerebral Resuscitation Study Group of the Belgian Society for Intensive Care.

The Glasgow coma score (GCS) during days 1-6 after cardiac arrest was used to predict neurological outcome in 360 resuscitated victims of out-of-hospital cardiac arrest. A predictive rule based on the best GCS of 216 patients resuscitated in 1983-84 (prediction group) was constructed, and its predictive power was tested on 133 patients treated in 1985 (test group). Neurological outcome was correctly predicted 2 days after cardiac arrest in 80% of the prediction group, with a best GCS of 10 or above and 4 or below as cutoff points. For patients with a best GCS of 5-9, prediction of outcome was possible 6 days after cardiac arrest, with a best GCS of 8 during the first 6 days as the single cutoff point. The rule was then validated in the test group: the sensitivity was 96%; the specificity 86%; the negative predictive value 97%; and the positive predictive value 77%. These data suggest that this simple GCS-based rule can be helpful in predicting outcome in patients resuscitated after out-of-hospital cardiac arrest, but confirmation of these data is required in a prospective study in a larger number of patients.
