Comparison of poison exposure data: NHIS and TESS data.
OBJECTIVE
To identify age-adjusted poisoning episode rates, and poison control center contacts due to poisonings in children under 6 years old based on 1997-1999 National Health Interview Survey data; and compare findings with 1997-1999 Toxic Exposure Surveillance System data.


METHODS
Secondary analysis of National Health Interview Survey poisoning episode data for children 5 years and younger. Respondents were asked about poison exposures during the previous 3 months.


RESULTS
Based on National Health Interview Survey population weighted data there were 196/10,000 poisonings to young children < 6 years. These exposures resulted primarily from harmful solid or liquid substances. A poison control center was called in 86% of exposures to children < 4 years, but only in 70% of the 4-5 year old exposures. The odds of a poison control center not being called were 3.2 times greater for 4-5 year olds (compared to < or = 3 years) and 4.5 times greater for African-American (compared with White-Americans). Comparison of National Health Interview Survey data with data in the 1997-1999 Annual Reports of the Toxic Exposure Surveillance System revealed the number of estimated exposures in the National Health Interview Survey data were approximately half those reported in the Toxic Exposure Surveillance System data. In both datasets, children 1-2 years of age had the highest percent of poisoning exposures.


CONCLUSIONS
Using multiple datasets to explore poisoning rates in young children provides a broader perspective. Differences in findings reflect divergent data collection methods and biases inherent in each database. Although the majority of National Health Interview Survey respondents reporting contacting a poison control center for a poisoning exposure, rates are lower in specific subgroups indicating a need for targeted educational efforts.
