Description
For all injury/poisoning episodes that occurred in the past 3 months for which the person spent at least one night in a hospital, IRIHNO reports how many nights the person was in the hospital.
IRIHNO is an injury-level variable.
IRIHNO is part of a series of variables initiated in 1997 that systematically report persons' injuries and poisonings, the cause, what the person was doing while sustaining the injury or poisoning, and where she/he was at the time of the injury or poisoning. For related variables and additional information, please see the User note on Injuries and Poisonings or use the IPUMS NHIS search function and drop-down menus.
Comparability
Prior to 2000, persons were asked about injuries and poisonings separately. To improve comparability across samples, IHIS integrated all episode level data as a single record type. Episodes that were originally released by NHIS in the poisoning files for 1997-1999 can be identified using the variable IRPOISYN.
