Each year, about 1,250,000 people in the United States experience an acute myocardial infarction (AMI). Emergency medical services (EMS) systems play a key part in the prehospital care and transportation of AMI patients. ⋯ In order to improve the prehospital care provided to AMI patients, this article by the Access to Care Subcommittee of the National Heart Attack Alert Program Coordinating Committee makes a number of recommendations regarding the staffing and equipping of EMS systems. The recommendations cover the "chain of survival" concept, universal and enhanced 9-1-1, emergency medical dispatching, ground ambulance specifications, automated external defibrillators, advanced life support coverage, medical direction, 12-lead electrocardiograms, and prehospital thrombolysis.

Comparative Study
Comparison of pediatric end-tidal CO2 measured with nasal/oral cannula circuit and capillary PCO2.
This study was designed to determine whether end-tidal carbon dioxide (ETCO2) values obtained by noninvasive oral/nasal cannula circuit with side-stream capnometry correlate reliably with capillary PCO2 (CapCO2) in a pediatric population without cardiopulmonary problems. Each patient was monitored until a reliable 5-minute ETCO2 waveform was obtained. A capillary blood gas sample was drawn while, simultaneously, ETCO2 was recorded. ⋯ A relative average bias of 1.96 with ETCO2 lower than CapCO2 was established with 95% limits of agreement of +/- 5.2 mm Hg (t = 5.71). Variability of difference scores was not related to range of mean scores (r = .08), age (r = .09), or respiratory rate (r = .25). End-tidal CO2 measured by an oral/nasal cannula capnometry circuit is a noninvasive method of assessing indirect measurements of PCO2 in a normal pediatric population.

This study's objectives were to determine the cost-effectiveness of introducing a transcription service into an emergency department (ED) and to determine the capacity of such a service to improve physician satisfaction. A prospective study of full-time emergency physicians was conducted in the ED of a community hospital in which a transcription service was introduced during peak periods of demand. Measurement was defined from a time-and-motion study consisting of direct observation by an industrial engineer who measured documentation time required for written and dictated charts. ⋯ When the records were transcribed, the mean subjective scores for satisfaction with the medical record improved from 2.1 to 3.6 (P = .0025) on a scale of 1 to 4. Surveys of nonemergency staff physicians documented that legibility score improved from 2.6 to 3.1 (P = .0056) and completeness improved from 2.6 to 3.0 (P = .0157), both on a scale of 1 to 4. It was concluded that dictating and transcribing ED medical records decreases the time required for documentation, improves record legibility and quality, allows more patients to be seen per physician-hour, and improves the satisfaction of emergency and nonemergency physicians.

Emergency medical telephone calls (ie, those made to 9-1-1 or 7-digit emergency numbers) are directed to emergency medical dispatchers (EMDs) who are responsible for quickly obtaining critical pieces of information from the caller, then activating an appropriate level of emergency medical services (EMS) response and providing the caller with patient care instructions until medical help arrives. The impact of well-trained, medically managed EMDs on the early care of potential acute myocardial infarction (AMI) patients is believed to be beneficial. However, standards for emergency medical dispatching vary widely across the nation. To improve emergency medical dispatching for AMI patients in the United States, this article by the Access to Care Subcommittee on behalf of the National Heart Attack Alert Program makes a number of recommendations regarding the use of medical dispatch protocols, provision of dispatch life support, EMD training, EMD certification, and emergency medical dispatch quality control and improvement processes.
