Criteria for dead-on-arrivals, prehospital termination of CPR, and do-not-resuscitate orders

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 judgment 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. To date, eight states and a number of local EMS systems have developed a varity of policies to address this dilemma. Currently, few services permit paramedics to terminate ACLS in the field when such efforts failt to achieve return to 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.
