• Most poison exposures (77%) were unintentional.  The Center also received calls about other types of poisonings: medication side effects, substance abuse, malicious poisonings, and suicide attempts. 
• 17,109 people (29.1%) called for poison-related information. Their questions were about possible problems with medication interactions, pesticide use, workplace chemicals, the safety of specific medications while breast-feeding, and many more topics.
• 45% of poison exposures involved children younger than six, but the most serious cases occurred in adolescents and adults.
• 56% of poison exposures involved medications; other exposures were to household or automotive products, plants, mushrooms, pesticides, animal bites and stings.

• 77% of poison exposures involved people who swallowed a drug or poison. People were also poisoned by inhalation and through exposures to the skin or eyes.
• 66% of poison exposures were safely managed over the phone and did not need medical treatment in a health care facility. However, 85% of those who called a poison center first, before gong to a health care facility were safety treated at home.

Poisonings: The National Picture

According to the Centers for Disease Control (CDC), in 2008 over 41,000 people died as a result of poisoning, and poisoning became the leading cause of injury death for the first time since at least 1980¹. The poisoning death rate nearly tripled over the past 30 years and the percentage of poisoning deaths that were caused by drugs increased from about 60% to about 90%¹. Nearly 9 out of 10 poisoning deaths are caused by drugs, and opioid pain medications were involved in more than 40% of all 2008 drug poisoning deaths, up from about 25% in 1999¹.   In 2008, about 76% of poisoning deaths were unintentional, 16% were suicides, and 8% were of undetermined intent².

According to data from the National Electronic Injury Surveillance System, nonfatal poisoning rates across all age groups are currently on the rise, even among age groups that had been enjoying an overall decline over the past decade².  The increase has been most dramatic among adults aged 20 years and older.  Children aged 6 to 12 have consistently had the lowest rate of nonfatal poisoning injury while teens and adults aged 20-59 have consistently had the highest rates. 

The National Capital Poison Center is one of 57 regional poison centers that serve the US.  Poison centers handled 2.4 million human poison exposures in 2010³, but this number does not reflect the magnitude of the national problem of poison-related injury and death since many poisonings do not involve a call to the poison center.  In 2010 there were 41,592 deaths attributed to poison², yet poison centers were consulted in only 1,730 poisoning fatalities³ (4%).  The CDC estimated that there were 1,098,880 poisoning injuries in 2010 that resulted in a visit to an emergency department².  However, poison centers were involved in only 601,197 cases that involved treatment at a health care facility, indicating that poison centers are not consulted for many poisoning-related ED visits³.  Poisonings also go unreported when people do not realize they have been exposed, choose not to seek medical treatment or advice, do not have access to medical care, or do not know about poison center services.
