Introduction

The pregnancy passport contains all the important medical information needed during pregnancy, at birth and for six weeks afterwards to ensure comprehensive care. This information is entered in the pregnancy passport by the treating healthcare providers, such as gynecologists, midwives and general practitioners, as well as institutions such as clinics, birthing centres, practices or midwife organizations.

The CH EPREG implementation guide describes the FHIR representation of the electronic pregnancy passport in Switzerland. It is dependent on CH Core and CH Term, which describe the Swiss-specific context, particularly in relation to the Swiss Electronic Patient Record (EPR).
This implementation guide is based on the concept for the exchange format of the electronic pregnancy passport (de, fr).

MustSupport

In the concept for the electronic pregnancy passport, the data elements are described in term of cardinality and conformity, which is then applied in the CH EPREG profiles (as long as it conforms to FHIR and the CH Core requirements). This table shows how the different levels of conformity are reflected in the FHIR profiles:

Concept (conformity)	FHIR profile (minimum cardinality and flag)
Mandatory: This is a required field. It must contain a valid value.	1..
Required: The field should always contain a valid value if possible.	0.. MS (mustSupport=true)
Optional: The field may contain a valid value.	0..

For CH EPREG the meaning of mustSupport follows also the IHE use of R2 (Required if known) as defined in ITI TF-2: Appendix Z:
If the sending application has data for the element, it is required to populate the element with a non-empty value. If the value ist not known, the element may be omitted. A receiving application may ignore the information conveyed by the element. A receiving application shall not raise an error solely due to the presence or absence of the element.

Cross Version Analysis

This is an R4 IG. None of the features it uses are changed in R4B, so it can be used as is with R4B systems. Packages for both R4 (ch.fhir.ig.ch-epreg.r4) and R4B (ch.fhir.ig.ch-epreg.r4b) are available.
