|SECTION 1 - PATIENT IDENTIFICATION DATA|
Patients date of birth.
Date of birth can be used to calculate the patients age, to distinguish between patients with the same name, and to provide discriminatory power in probabilistic linkage of patient records.
Time can be included for newborns. Date of birth can be estimated from the patients age (see method recommended under TS - time stamp in the Technical Notes at the end of this document).
Data Type (and Field Length)
TS - time stamp (26).
Year, month, and day of birth are entered in the format YYYYMMDD. For example, a birth date of August 12, 1946, would be encoded as 19460812. Date and time of birth are entered in the format YYYYMMDDHHMM. For example, a birth at 10:30 pm on June 1, 1997, would be encoded as 199706012230.
