Cost comparison of searching the Iowa Drug Information Service index manually and by computer.

A cost comparison of searching the Iowa Drug Information Service index manually and by computer is presented. Identical searches were performed on a computer system and by hand. The searches were timed and the results compared. Costs of start-up, maintenance, and operation were calculated for the manual and computer systems. Both systems yielded a similar number of relevant references. Start-up and maintenance costs were found more expensive for the computer system, but operational costs were less expensive (p less than 0.05). Operational costs varied according to the number of uses per year. Operational costs were found to increase faster for the manual system than the computer system. At 980 uses per year, the overall cost of the computer system was less than the manual system. A dedicated microcomputer system to search the Iowa Drug Information Service index was found less costly than, and as effective as, the common manual system.

A public health approach to emergency medicine: preparing for the twenty-first century.

This paper focuses on the implications of an inadequate public health/preventive health care system for emergency medicine (EM), the role that EM providers can play in remedying critical health problems, and the benefits gained from a public health approach to EM. A broad definition of public health is adopted, suggesting shared goals of public health and EM. Critical problems posed for EM include alcohol, tobacco, and other drug abuse; injury; violence; sexually transmitted diseases and human immunodeficiency virus (HIV) infection occupational and environmental exposures; and the unmet health needs of minorities and women. A blueprint for future merging of public health issues with EM is presented that includes the application of public health principles to 1) clinical practice; 2) public education, community involvement, and public policy advocacy; 3) development of medical school and residency public health/prevention curricula and teaching methods; and 4) research opportunities and surveillance. Finally, recommendations are proposed that require restructuring the present health care system to provide resources, incentives, and organizational changes that promote an integration of public health and preventive services in the practice of EM.

Prospective multicenter evaluation of cocaine-associated chest pain. Cocaine Associated Chest Pain (COCHPA) Study Group.

OBJECTIVE: To describe a large cohort of patients who had chest pain following cocaine use, and to determine the incidence of and clinical characteristics predictive for myocardial infarction in this group of patients. METHODS: A prospective observational cohort study of consecutive patients with cocaine-associated chest pain was conducted in six municipal hospital emergency departments (EDs). Demographic variables, drug abuse patterns, medical histories, chest pain characteristics, ECG results, and laboratory data were recorded. Myocardial infarction was the primary endpoint. RESULTS: Fourteen of 246 patients (5.7%; 95% confidence interval [CI], 2.7-8.7%) had myocardial infarction, as diagnosed by elevated CK-MB isoenzyme levels. There were two deaths (0.8%). The patients had a median age of 33 years. The majority were male (71.5%), non-white (83.3%), cigarette smokers (83.3%) who used cocaine regularly. Chest pain began a median of 60 minutes after cocaine use and persisted for a median of 120 minutes. Chest pain was most frequently described as substernal (71.3%) and pressure-like (46.7%). Shortness of breath (59.3%) and diaphoresis (38.6%) were common. There was no clinical difference between patients who had myocardial infarctions and those who did not. Twelve patients had arrhythmias and four had congestive heart failure. All cases requiring intervention were evident upon presentation. An ECG revealing ischemia or infarction had a sensitivity of 35.7% for predicting a myocardial infarction. The specificity, positive predictive value, and negative predictive value of the ECGs were 89.9%, 17.9%, and 95.8%, respectively. CONCLUSIONS: Myocardial infarction in patients who have cocaine-associated chest pain is not uncommon. No clinical parameter available to the physician can adequately identify patients at very low risk for myocardial infarction. Therefore, all patients with cocaine-associated chest pain should be evaluated for myocardial infarction.
