2007 ANNUAL REPORT OF THE AMERICAN ASSOCIATION OF POISON CONTROL CENTERS' NATIONAL POISON DATA SYSTEM (NPDS): 25TH ANNUAL REPORT

Background: This report is the 25th Annual Report of the American Association of Poison Control Centers (AAPCC; http://www.aapcc.org) National Poison Data System (NPDS). During 2007, 60 of the nations 61 U.S. Poison Centers upload case data automatically. The median upload time is 14 [5.3, 55] (median [25%, 75%]) min creating a real-time national exposure database and surveillance system. Methodology: We analyzed the case data tabulating specific indices from NPDS. The methodology was similar to that of previous years. Where changes were introduced, the differences are identified. Fatalities were reviewed by a team of 29 medical and clinical toxicologists and assigned to 1 of 6 categories according to Relative Contribution to Fatality. Results: Over 4.2 million calls were captured by NPDS in 2007: 2,482,041 human exposure calls, 1,602,489 information requests, and 131,744 nonhuman exposure calls. Substances involved most frequently in all human exposures were analgesics (12.5% of all exposures). The most common exposures in children less than age 6 were cosmetics/personal care products (10.7% of pediatric exposures). Drug identification requests comprised 66.8% of all information calls. NPDS documented 1,597 human fatalities. Conclusions: Poisoning continues to be a significant cause of morbidity and mortality in the United States NPDS represents a valuable national resource to collect and monitor U.S. poisoning exposure cases. It offers one of the few real-time surveillance systems in existence, provides useful data, and is a model for public health surveillance.

2006 Annual Report of the American Association of Poison Control Centers' National Poison Data System (NPDS).

Abstract Background: The American Association of Poison Control Centers (AAPCC; http://www.aapcc.org ) maintains the National Poison Data System (NPDS). Today, 60 of the nations 61 US poison centers upload case data automatically. Most upload every 1- 60 minutes (median 11 minutes) to NPDS creating a real-time national exposure database and surveillance system. Methodology: We analyzed the case data tabulating specific indices from NPDS. The methodology was similar to that of previous years. Where changes were introduced, the differences are identified. Fatalities were reviewed by a team of 27 medical and clinical toxicologists and assigned to 1 of 6 categories according to Relative Contribution to Fatality (RCF). Results: Over 4 million calls were captured by NPDS in 2006: 2,403,539 human exposure calls, 1,488,993 information requests, and 128,353 nonhuman exposure calls Substances involved most frequently in all human exposures were analgesics. The most common exposures in children less than age 6 were cosmetics/personal care products. NPDS documented 1,229 human fatalities. Conclusions: Poisoning continues to be a significant cause of morbidity and mortality in the US. NPDS represents a valuable national resource to collect and monitor US poisoning exposure cases. It offers one of the few real-time surveillance systems in existence, provides useful data and is a model for public health surveillance.

WILLINGNESS TO PAY FOR POISON CONTROL CENTERS

We used the willingness-to-pay (WTP) method to value the benefits of poison control centers when direct access was blocked, comparing WTP among: (1) blocked callers (n = 396), (2) callers after access was restored (n = 418), and (3) the general population (n = 119). Mean monthly WTP was

2.55 (general population). Blocked and non-blocked callers had a significantly higher WTP than general population respondents (p < 0.001). We conclude that the WTP method measured benefits that are difficult to quantify; however, WTP surveys need to be carefully conducted to minimize bias. We discuss how this approach could be useful for other health care services.

The role of clinical toxicologists and poison control centers in public health.

OBJECTIVES The authors examined the costs and outcomes resulting from a natural experiment during which direct public access to poison control centers was restricted and then restored. METHODS Both societal and health care purchaser perspectives were used. Probability data were obtained from a natural experiment during which public callers from a large county in California were electronically blocked from directly accessing the poison control center. Callers were referred to 911, which had direct access to the poison control center, if they thought they had a poisoning emergency. We conducted telephone interviews of: (a) persons who attempted to call the poison control center for a childs poisoning exposure but who did not have direct access (n = 270) and (b) persons who called the poison control center after direct access was restored (n = 279). Cost data were obtained from primary data collection and from other sources. The outcome measure was the appropriateness of the treatment location (at home or at a health care facility). Caller-reported outcomes were also examined. RESULTS The average additional cost per blocked call was

33.14 from a health care purchaser perspective. Fourteen percent of callers with restricted access were treated at an inappropriate location, compared with only 2% of callers with direct poison control center access. Also, 14% did not obtain any professional advice after they attempted to call the poison control center, although 66% of these cases involved potentially toxic substances. Results were robust across a range of sensitivity analyses. CONCLUSION Restricting direct public access to poison control centers created additional costs to society, the health care sector, and callers.

Health care cost effects of public use of a regional poison control center

Deaths from drug overdose have become the leading cause of injury death in the United States, where the poison center system is available to provide real-time advice and collect data about a variety of poisonings. In 2012, emergency medical providers were confronted with new poisonings, such as bath salts (substituted cathinones) and Spice (synthetic cannabinoid drugs), as well as continued trends in established poisonings such as from prescription opioids. This article addresses current trends in opioid poisonings; new substances implicated in poisoning cases, including unit-dose laundry detergents, bath salts, Spice, and energy drinks; and the role of poison centers in public health emergencies such as the Fukushima radiation incident.
