Resource Profile: US Public Health Pregnancy Status Observation

Defining URL:http://hl7.org/fhir/us/ecr/StructureDefinition/us-ph-pregnancy-status-observation
Version:2.0.0
Name:USPublicHealthPregnancyStatusObservation
Title:US Public Health Pregnancy Status Observation
Status:Active as of 1/18/22 12:57 PM
Definition:

This profile represents current and/or prior pregnancy statuses and their date ranges, enabling investigators to determine if a patient was pregnant, possibly pregnant, not pregnant or whether the pregnancy status was unknown during a particular date range.

The subject of this profile is the mother.

This profile includes the determination method, determination date, and recorded date of the pregnancy status.

Use the effectivePeriod to indicate the date range over which the patient was pregnant/possibly pregnant/not pregnant/unknown. To record the date that the pregnancy status was recorded, use the date-recorded-extension and to record the date on which the pregnancy status determination was made, use the date-determined-extension. If the effectivePeriod.end is not present it is assumed that the date range over which the pregnancy status is asserted is from effectivePeriod.start to the date in the date-recorded-extension. For example, if the effectivePeriod.start has been recorded as two months prior to the date contained in the date-recorded-extension, and there is no effectivePeriod.end recorded, no assumptions can be made about the pregnancy status after the date contained in the date-recorded-extension.
