Record Coding

Records Included in the PNSS Tables
PNSS is a pregnancy-based system with only one record for each pregnancy included in the table analysis.
  • Prenatal data are collected at the first prenatal visit to the clinic and postpartum data are collected at the postpartum visit after delivery. PNSS contributors combine information from these different time periods into a single record.
  • Records are selected based on the infant's date of birth or expected date of birth for the reporting period of January 1 through December 31.

In the PNSS data tables, records are coded as follows:

  • A complete record contain both prenatal and postpartum information.
  • A prenatal record contains only data that were collected when the woman enrolled in the public health program during pregnancy.
  • A postpartum record contains data that were collected when the woman entered the program after delivery.

Prenatal and postpartum records represent records that could not be linked as a complete record because data from one time period was missing. These records are included in the table analysis.
