Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
Poisoning is defined as ingestion, inhalation, injection, or cutaneous absorption of a drug, toxin (biologic or non-biologic), or other chemical agent in a quantity sufficient to cause a harmful effect. This category does not include harmful effects from normal therapeutic drugs (i.e., unexpected adverse effects to a drug administered correctly to treat a condition) or food poisoning.
NEISS does not use ICD codes. However, reporters are given extensive training and report any poisoning cases in the emergency department record. A detailed description of the methods for coding poisoning injuries has been published elsewhere.
Data by race are not reported because multiple race data are not typically available from the emergency department records.
Emergency department visit rates are calculated using the new bridged-race postcensal population estimates of the resident population of the United States for the data year involved. For census years (e.g. 2010), population counts enumerated as of April 1 are used. For all other years, populations estimates as of July 1 are used. Intercensal population estimates are used in rate calculations for the years between censuses (e.g. 1991-1999, 2001-2009). Please note that postcensal population estimates for years after the last census year are updated annually, which means that rates prior to the update may be different.
This Indicator uses Age-Adjustment Groups:
Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.
In 2013, rates for 2008 and 2009 were revised using intercensal population estimates based on the 2000 and 2010 censuses instead of the postcensal estimates for the denominator. The original baseline was revised from 304.4 to 304.8. The target was adjusted from 304.4 to 304.8 to reflect the revised baseline using the original target-setting method.
