Resource Profile: HCIM Pregnancy DateLastMenstruation

An Observation resource as defined by the Dutch HCIM Pregnancy v3.1(2017EN).

Pregnancy or gravidity is the condition in which a woman carries a fertilized egg, which grows into an embryo and then a fetus. A pregnancy of between 37 and 42 weeks is considered normal. ‘Term pregnancy’ is 37 to 42 weeks. The term gravidity is also used for the number of times a woman has been pregnant. This and parity - the number of times a woman has given birth - provides insight into the patient’s obstetric history.

Purpose of HCIM

If the patient is pregnant, it is important to mention this, as it requires specific attention in their care. Pregnancy can influence treatment decisions, the treatment itself and the patient’s care.

Purpose of this profile

This profile implements the DateLastMenstruation field of the HCIM. It complements the zib-Pregnancy profile, which tracks the overarching condition. This profile can be referenced with the Observation.zib-Pregnancy field (event-partOf extension).

Usages:

• This Profile is not used by any profiles in this Implementation Guide
