Out-of-hospital provider use of epinephrine for allergic reactions: pilot program.
OBJECTIVE
To describe experience with an out-of-hospital provider program for the recognition and field management of allergic reactions by advanced life support (ALS) and basic life support (BLS) providers.


METHODS
Data sheets completed between June 1, 1988, and August 31, 1993, and records from receiving sites (physicians' offices or EDs) were reviewed for information regarding the presentation of the allergic reaction, the time course and treatment provided out of hospital, and the clinical outcome at the receiving health care facility.


RESULTS
Thirty-seven data sheets were completed during the study period. Fourteen (38%) of the providers were BLS providers. The epinephrine was supplied from the emergency medical services (EMS) provider's personal kit in 35% of the cases, from an EMS vehicle in 57% of the cases, and by the patient in 8% of the cases. Availability of the kits allowed administration of epinephrine prior to the arrival of the first EMS vehicle in 41% of the instances and prior to physician on-line medical command in 65% of all the instances (predominantly by BLS providers). Overall, 77% of the patients experienced alleviation of their symptoms of respiratory difficulty, swelling, or rash after epinephrine administration, while 20% were unchanged and 3% worsened. All patients receiving epinephrine had an ED diagnosis of allergic reaction, and no adverse event was encountered on follow-up of the patients treated.


CONCLUSIONS
Severe allergic reactions can be reliably identified and safely managed by out-of-hospital providers, including BLS providers. Providing personal anaphylactic treatment kits and increasing the pool of providers trained to manage allergic reactions (including BLS providers) can often decrease the time to treatment.
