A nonfatal intentional self harm injury is defined as an injury or poisoning resulting from a deliberate violent act inflicted on oneself with the intent to take one's own life or with the intent to harm oneself. Both confirmed and suspected intentional self harm is included.
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.

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 125.3 to 124.9. The target was adjusted from 112.8 to 112.4 to reflect the revised baseline using the original target-setting method.
