A poison control center is a medical service that is able to provide immediate, free, and expert treatment advice and assistance over the telephone in case of exposure to poisonous or hazardous substances. Poison control centers answer questions about potential poisons in addition to providing treatment management advice about household products, medicines, pesticides, plants, bites and stings, food poisoning, and fumes. In the US, more than 72% of poison exposure cases are managed by phone, greatly reducing the need for costly emergency department and doctor visits. History After World War II there was a proliferation of new drugs and chemicals in the marketplace, and consequently suicide and childhood poisonings from these agents drastically increased. Around this time up to half of all accidents in children were poisonings with a substantial number of fatalities. These factors led to the medical community developing a response to both unintentional and intentional poisonings. In Europe in the late 1940s special toxicology wards were set up; initial wards were started in Copenhagen and Budapest, and the Netherlands began a poison information service. In the United States during the 1930s, Louis Gdalman, a pharmacist knowledgeable in the chemistry of harmful substances, set up a poison information service at St. Luke's Hospital (Chicago, Illinois). He became known around Chicago and the country as the person to contact in a poisoning case and would take calls at home around the clock. In the late 1940s, Gdalman began to organize the poison information onto note cards and created a standardized form to collect new information on new toxic substances. By 1953 he had collected an extensive library of information on thousands of poisons and he established the first Poison Control Center along with Edward Press. By 1957 there were 17 poison control centers in the U.S., with the Chicago center serving as a model; these centers dealt mainly with physician enquiries by giving ingredient and toxicity information about products, along with treatment recommendations. Over time the poison control centers started taking calls from the general public. The majority of poison centers were not part of a patient treatment facility; they strictly provided information. In 1958 the American Association of Poison Control Centers (AAPCC) was founded to promote cooperation between poison centers in different cities and to standardize the operation of these centers. An additional part of the AAPCC's activities was poison prevention and education programs for both physicians and
