Vital signs records omissions on prehospital patient encounter forms.
A reported in-field, prospective evaluation of 227 prehospital patient assessments by advanced life support (ALS) emergency medical technicians (EMTs) found a frequent failure to measure vital signs. The objective of this retrospective review was to report the omission frequency of vital signs found in a centralized emergency medical services (EMS) data collection system. ⋯ This study found a frequent failure by non-metropolitan basic life support (BLS) and advanced life support (ALS) EMTs to record vital signs on prehospital emergency patient encounter forms. It supports a previous report of direct in-field observations of ALS EMTs failing to measure vital signs during patient assessment. The impact of vital sign omissions upon individual patient care can be assessed only by receiving medical control physicians. In the absence of effective emergency physician networking, the statewide magnitude of the problem among BLS and ALS EMTs has not been recognized as a system issue.

To enhance comparability in reports on survival from out-of-hospital cardiac arrest, an international task force recently developed a set of guidelines for uniform terminology, definitions, and data collection for outcome research on cardiac arrest--the Utstein style. Because the data collection recommended is limited to information available through emergency medical services systems, the potential for bias in comparisons of cardiac arrest outcomes remains. By expanding data collection to include the identification of all cases of cardiac arrest in the community, including patients who do not present for care by an emergency medical services system, a population-based approach can be achieved. We review the strengths and limitations of both emergency medical services-based and population-based data collection to assess outcomes of cardiac arrest, outline practical steps required to implement a population-based approach, and suggest that extension of the Utstein style guidelines to include all cardiac arrest cases within a defined population is needed to minimize potential bias in comparisons of cardiac arrest outcomes across communities or over time.

Practice Guideline GuidelineChanges in guidelines for cardiopulmonary resuscitation and emergency cardiac care.
At the Fifth National Conference on Cardiopulmonary Resuscitation and Emergency Cardiac Care held in Dallas in February 1992, changes in the guidelines for basic life support and advanced cardiac life support were recommended. These changes are defined and explained in this article.

In contrast to the current consensus that governs the mechanics of prehospital advanced cardiac life support (ACLS), uniform criteria for determining when to initiate, withhold, or terminate ACLS in the field do not exist. Most emergency medical services (EMS) permit paramedics and other prehospital providers to withhold resuscitation when the victim obviously is dead, but the accuracy and appropriateness of this judgement in the field have not been subjected to empiric research. Do-not-resuscitate orders on patients in community settings often are problematic when paramedics and other prehospital providers are governed by standing orders that require them to initiate CPR when it is indicated medically. ⋯ Currently, few services permit paramedics to terminate ACLS in the field when such efforts fail to achieve return of spontaneous circulation. Studies have demonstrated convincingly that the rapid transport of such patients for further attempts at resuscitation in the hospital yields dismal rates of survival. The costs, risks, and benefits of this practice in community settings must be reviewed carefully to allocate EMS resources in an optimal manner.

The article consists in a review of the development of prehospital care in Finland and of emergency medical services in Helsinki. Based on 20 years' accumulated experience at a physician staffed prehospital emergency care unit in Helsinki, emergency medical services throughout the country have begun implementing the various links in the 'chain of survival' concept.
