Poison centers as information resources for volunteer EMS in a suspected chemical exposure.

In the early part of chemical terrorism or hazardous materials events, protective actions and patient care require empirical decisions because reliable and accurate information may not be readily available. It has become increasingly important to identify reliable information resources that are the most likely to be accessed for information during these events. We sought to identify information resources that volunteer Emergency Medical Services (EMS) providers would use during a suspected chemical exposure. Survey questionnaires were completed by 116 of 151 (76.8%) suburban and rural EMS providers. In the past 12 months, most participants used medical journals and textbooks (59.5%), internet sites (57.8%), and poison centers (55.2%) as information resources. For two hypothetical scenarios involving chemical exposures, poison centers were most frequently chosen as likely contacts for information regarding the identity of the agent (case 1: 52.6%, case 2: 48.3%), treatment (74.1%, 64.7%, respectively), and antidote (59.5%, 49.1%, respectively). Fire department hazardous materials team tied with poison centers as the highest for chemical agent in the second scenario (48.3%) and was ranked highest both for decontamination (75.0%, 64.7%, respectively) and personal protection (56.9%, 45.7%, respectively). Poison centers were selected as the best resource for timely information (70.7%), availability (69.0%), and ease of contact (72.4%), and second highest for knowledge of chemical agents (44.0%), after CHEMTREC (56.9%). Finally, poison centers and CHEMTREC received the highest overall ratings (28.4% and 26.7%, respectively). Poison centers are viewed as an important information resource by EMS providers and may be the most commonly sought resource for various information needs during a suspected chemical exposure.
