Data Element
Version 2010A1

Data Element Name: Birthdate
Collected For: All Records
Definition:The month, day, and year the patient was born.

For discharge measures, e.g., HBIPS-1, 4, 5, 6, 7, All PC measures, patient's age (in years) is calculated by Discharge Date minus Birthdate. For event measures, e.g., HBIPS-2, 3, patient's age at time of event (in years) is calculated by Event Date minus Birthdate. The algorithm to calculate age must use the month and day portion of birthdate, and discharge date or event, as appropriate to yield the most accurate age.

Suggested Data Collection Question:What is the patient’s date of birth?
Length:10 – MM-DD-YYYY (includes dashes)
Allowable Values:

MM = Month (01-12)
DD = Day (01-31)
YYYY = Year (1880-9999)

Notes for Abstraction:Because this data element is critical in determining the population for all measures, the abstractor should NOT assume that the claim information for the birthdate is correct. If the abstractor determines through chart review that the date is incorrect, she/he should correct and override the downloaded value. If the abstractor is unable to determine the correct birthdate through chart review, she/he should default to the date of birth on the claim information.
