Resource Profile: US Public Health Is Postpartum

Official URL: http://hl7.org/fhir/us/ph-library/StructureDefinition/us-ph-is-postpartum Version: 2.0.0
Standards status: Trial-use Active as of 2025-10-23 Maturity Level: 3 Computable Name: USPublicHealthIsPostpartum
Other Identifiers: OID:2.16.840.1.113883.4.642.40.58.42.33

This Observation profile represents whether or not the patient is postpartum.

It is based on the US Core Simple Observation Profile profile and further constrains it:

  • sets Observation.category to "social-history social history"
  • sets Observation.code to "Maternal condition during puerperium (observable entity)"
  • further constrains Observation.subject to the US Public Health Patient
  • binds Observation.value[x] to the Yes/No/Unknown/Not asked value set

The postpartum period, also known as the puerperium, refers to the time after delivery when maternal physiological changes related to pregnancy return to the nonpregnant state. There is consensus that the postpartum period begins upon delivery of the infant. The end is less well defined but is often considered the six to eight weeks after delivery because the effects of pregnancy on many systems have largely returned to the pre-pregnancy state.
