Validation of an algorithm to estimate gestational age in electronic health plan databases.

ABSTRACT:

Purpose

To validate an algorithm that uses delivery date and diagnosis codes to define gestational age at birth in electronic health plan databases.

Methods

Using data from 225,384 live born deliveries to women aged 15-45 years in 2001-2007 within eight of the 11 health plans participating in the Medication Exposure in Pregnancy Risk Evaluation Program, we compared (1) the algorithm-derived gestational age versus the "gold-standard" gestational age obtained from the infant birth certificate file and (2) the prenatal exposure status of two antidepressants (fluoxetine and sertraline) and two antibiotics (amoxicillin and azithromycin) as determined by the algorithm-derived versus the gold-standard gestational age.

Results

The mean algorithm-derived gestational age at bir
