Birth And Fetal Death (BFDR) FHIR Implementation Guide
2.0.0 - STU2 United States of America flag

Birth And Fetal Death (BFDR) FHIR Implementation Guide, published by HL7 International / Public Health. This guide is not an authorized publication; it is the continuous build for version 2.0.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/fhir-bfdr/ and changes regularly. See the Directory of published versions

Resource Profile: Observation - Number of Prenatal Visits

Official URL: http://hl7.org/fhir/us/bfdr/StructureDefinition/Observation-number-prenatal-visits Version: 2.0.0
Active as of 2024-09-16 Computable Name: ObservationNumberPrenatalVisits
Other Identifiers: OID:2.16.840.1.113883.4.642.40.13.42.73

The total number of prenatal visits for the mother. The dates of the first and last prenatal visit are indicated by the effective date range. If the mother received no prenatal care, the value should indicate 0 visits.

The edit flag extension supports validation as part of the Jurisdiction to NCHS use case and can be ingnored for the provider to jurisdiction use case. The validation checks are done at the jurisdiction prior to sending to the National Statistical Agency and are based on the item specific edit criteria specified in the Birth Edit Specifications for the 2003 Proposed Revision of the U.S. Standard Certificate of Birth and the Fetal Death Edit Specifications for the 2003 Revision of the U.S. Standard Report of Fetal Death.
