IRDAYSUB
Upper bound on days between injury and interview recode

Codes

This is a 4-digit numeric variable.

Description

For all injury and poisoning episodes, IRDAYSUB reports the upper bound of the number of days that elapsed between the injury or poisoning episode and the interview date. IRDAYSLB reports the lower bound of the number of days that elapsed between the injury or poisoning episode and the interview date. These upper and lower bounds are to be used for injury or poisoning episodes with incomplete information regarding the timing of the injury or poisoning episode.

The NHIS recoded variable IRDAYSR reports the number of days between the injury or poisoning and the interview date. If the respondent could not recall the exact timing of the injury or poisoning, the interviewer a series of follow up questions to establish the approximate timing of the episode. For injuries with complete information, the values for the upper and lower bounds will be equal to the value of IRDAYSR. Imputed values for IRDAYSR are identified by the variable IRTIMEFLG.

IRDAYSUB is an injury-level variable.

IRDAYSUB 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.
