Injury due to self-harm

#1

Is there a variable that can be used to distinguish whether an injury is due to self-harm? If there is none, could I possibly link the NHIS data to a hospitalization file to determine an ICD code of intentional self-harm? Thank you.

Unfortunately, it does not look like we currently have any variables available that would enable you to identify injury due to self-harm as outlined by the ICD-10-CM codes. However, you should be able to link IPUMS NHIS data to the hospitalization data. This page details information about linking NHIS public use files to IPUMS NHIS files.
