ePMA Implementation Guidance for FHIR STU3

This guidance is under active development by NHS Digital and content may be added or updated on a regular basis.
Please note: This guidance has been superseded by the Implementation guide for digitial medicines, which contains up-to-date information.

Element: effective[x] or

Mandatory when the status is intended otherwise Required. Either:

  • effectiveDateTime a date time at which the medication started or should start
  • effectivePeriod the period over which the patient has taken or should take the medication

The use of effectivePeriod is to be preferred, and should start when the medication started in any preceding episode of care.

The date / time format allows various degrees of date resolution; year, year/month and exact date so an approximate date can be used when the exact date is not known.

Where the end date is unknown it may be omitted.
