This study reviewed 549 malpractice claims filed against emergency physicians in Massachusetts from 1975 through 1993, with a total of $39,168,891 of indemnity and expense spent on the 549 closed claims. High-risk diagnostic categories (chest pain, abdominal pain, wounds, fractures, pediatric fever/meningitis, epiglottitis, central nervous system bleeding, and abdominal aortic aneurysm) accounted for 63.75% of all closed claims and 64.23% of the total indemnity and expense spent on closed claims. Missed myocardial infarction (chest pain) claims accounted for 25.47% of the total cost of closed claims but only 10.38% of closed claims. ⋯ The frequency of high-risk claims decreased in the post-1988 group, largely because of the decline in fracture and wound claims. The category of missed myocardial infarction had a larger percentage of claims closed with indemnity payment than without indemnity payment. This parameter may serve as a marker for the overall seriousness of claims associated with a particular allegation, unlike the average cost per claim, which may be skewed by a few large awards.

The metered-dose inhaler (MDI) techniques of 125 asthma patients who presented to a county hospital emergency department (ED) were evaluated. Correct technique was divided into 7 steps. Twenty-one percent of the patients performed all 7 steps correctly. ⋯ The Vitalograph Aerosol Inhalation Monitor was used to verify correct patient technique and as a teaching aid with variable success. Education in proper use of the MDI is important in the overall care of the asthma patient; however, instruction requires a definite time commitment and may not be feasible for all patients in a busy ED. For some patients, alternatives that require less lengthy instruction, such as the use of breath-actuated devices, spacers, and reservoirs, may be required.

This study examined the concordance of radiographic readings between emergency department (ED) attending physicians and radiologists in a community teaching hospital. In addition, the incidents of misinterpretations leading to an alteration in patient care were also reviewed. All radiographs obtained from January through October 1993 were initially interpreted by ED attending physicians with subsequent final review by attending radiology staff. ⋯ The most frequently obtained radiographs included: chest, 7,012 (0.33% MR-FU); cervical spine, 1,112 (0.18% MR-FU); ankle, 758 (0.66% MR-FU); knee, 633 (0.32% MR-FU); and foot, 621 (0.97% MR-FU). In this study, 99.0% of all emergency department radiographs were read correctly on initial review by ED attending physicians. Of all misread radiographs, less than half (46%) were deemed clinically significant and required a follow-up intervention.

Comparative Study
End-tidal carbon dioxide changes during cardiopulmonary resuscitation after experimental asphyxial cardiac arrest.
A study was undertaken to determine the pattern of end-tidal carbon dioxide (ETCO2) changes during asphyxia-induced cardiac arrest in a pediatric canine model. Eleven intubated, anesthetized, paralyzed dogs (mean age, 4.1 mo; mean weight, 5.5 kg) were used. Asphyxia was induced by clamping the endotracheal tube (ETT) and discontinuing ventilation. ⋯ This pattern, not previously described, is different from that observed in animal and adult cardiac arrest caused by ventricular fibrillation, during which ETCO2 decreases to almost zero after the onset of arrest, begins to increase after the onset of effective CPR, and increases to normal levels at ROSC. In this model of asphyxial arrest, continued cardiac output prior to arrest allows continued delivery Of CO2 to the lungs, resulting in higher alveolar CO2; this, in turn, is reflected as increased ETCO2 once ventilation is resumed during CPR. Further study is needed to determine whether the pattern Of ETCO2 changes can be used prospectively to define the etiology of cardiac arrest.
