x The authors hypothesized that data analysis in the current emergency medicine literature uses relatively few methods and sought to determine the frequency distributions of each method of analysis. The authors defined their population as original contributions in three refereed emergency medicine journals from September, 1985 through July, 1989. Letters to the editor, brief reports, reviews, and case reports were excluded. The authors reviewed 250 randomly selected articies and identified the method(s) of data analysis in each.

x Emergency department (ED) cardioversion and discharge of atrial fibrillation (AF) is an evolving treatment. Emergency department cardioversion patients have few comorbidities, and their discharge directly from the ED leads to a sicker in-patient population of AF patients. This study examines whether the quality care markers, hospital charges (HC) and length of stay (LOS), negatively reflect the practice of ED cardioversion.

x The reduction of quantitative diagnostic test scores to the dichotomous case is a wasteful and unnecessary simplification in the era of high-speed computing. Physicians could make better use of the information embedded in quantitative test results if modern generalized curve estimation techniques were applied to the likelihood functions of Bayes' theorem. Hand calculations could be completely avoided and computed graphical summaries provided instead. Graphs showing posttest probability of disease as a function of pretest probability with confidence intervals (POD plots) would enhance acceptance of these techniques if they were immediately available at the computer terminal when test results were retrieved.

x The objective of this study was to describe individual and practice characteristics of Canadian emergency physicians, and to determine if these characteristics varied with geographic region, type of certification, or method of reimbursement. The study took place in emergency departments across Canada, and all full-time physicians with certification in emergency medicine, and a random sample of Canadian Association of Emergency Physician members without certification were surveyed with a 23-item questionnaire.

x The aim of this present study was to compare the diagnostic accuracy and reproducibility of 2 clinical decision rules (the Ottawa Knee Rules [OKR] and Pittsburgh Decision Rules [PDR]) developed for selective use of x-rays in the evaluation of isolated knee trauma. Application of a decision rule leads to a more efficient evaluation of knee injuries and a reduction in health care costs. The diagnostic accuracy and reproducibility are compared in this study.
Incidence of urethral disruption in females with traumatic pelvic fractures C.Tom Carter, Nathan Schafer

x According to the National Center for Health Statistics, in 1986 1.4 million female patients in the United States were admitted to inpatient and short-stay nonfederal hospitals as a result of injuries acquired secondary to trauma. Of these, 45,000 had traumatic pelvic fractures. Rupture of the urethra is the most important lower urinary tract injury associated with traumatic pelvic fracture because of the high incidence of serious complications, such as urethral stricture and incontinence. To our knowledge, there are no satisfactory studies in the English literature documenting the incidence of urethral disruption in females with traumatic pelvic fractures.

x The ED is often confronted with long waiting periods. Because of the progressive shortage in general practitioners, further growth is expected in the number of patients visiting the ED without consulting a general practitioner first. These patients mainly present with minor injuries suitable for a standardized diagnostic protocol. The question was raised whether these injuries can be treated by trained ED nurses (specialized emergency nurses [SENs]). The aim of this study was to evaluate the diagnostic accuracy and reproducibility of SENs in assessing ankle sprains by applying the Ottawa Ankle Rules (OAR) and Ottawa Foot Rules (OFR).

x Twenty-three chapters of the American Red Cross located in the Northeast participated in this study of achievement in adult cardiopulmonary resuscitation (CPR) classes. Sixty-eight classes offered to the public were studied by a pencil-and-paper survey and a specially developed written test. This study locates student, instructor, and course factors associated with achievement in CPR classes. Student factors found to be significant predictors of achievement were reading difficulty, age, and prior CPR training.

x The purpose of this report is to determine the reliability and sensibility of the currently available prehospital rating scales by a prospective evaluation of ambulance call reports using generalizability methodology. Sequential samples of emergency call data from the Hamilton Base Hospital Paramedic program database were used to sample calls randomly for a two-phase study. Phases I and II used blinded ambulance call report forms presented to six raters during three sessions in each phase. Generalizability (reliability) coefficients were then generated to determine the degree of reliability for the scales in both phases of the study.

x B-Type natriuretic peptide (BNP) values greater than 400 pg/mL have high positive likelihood ratio (>10) for the diagnosis of clinical congestive heart failure (CHF). However, in patients with CHF, it is not known what correlation, if any, exists for the BNP levels above 400 pg/mL and the findings on the initial chest x-ray (CXR).

x In this article we describe characteristics of emergency encounters for patients with a diagnosis of acute cardiac ischemia (ACI) and for patients with chest pain complaints. Data are from the National Hospital Ambulatory Medical Care Survey, which includes abstracts from the medical records of a national probability sample of visits to emergency departments (ED). Analysis was limited to records of patients 25 years of age and older with a diagnosis of either confirmed or suspected acute myocardial infarction (AMI) or unstable angina pectoris and records with a nontraumatic chest pain complaint.

Published in issue: October 1997
x Many of the costs associated with prehospital care in developed countries are covered in budgets for fire suppression, police services, and the like. Determining these costs is therefore difficult. The costs and benefits of developing a prehospital care system for Kuala Lumpur, Malaysia, which now has essentially no emergency medical services (EMS) system, were estimated. Prehospital therapies that have been suggested to decrease mortality were identified. A minimal prehospital system was designed to deliver these treatments in Kuala Lumpur.
