Guidance

This profile defines a specific recommended activity as part of an intervention recommended by a specific Recommendation.

The actions defined using this profile are combined to a plan using the Recommendation Plan profile.

The following profiles are used to define specific actions:

• Body Positioning Action - for describing the action of positioning a patient
• Drug Administration Action - for describing the action of administering a drug
• Assessment Action - for describing the action of assessing a patient
• Procedure Action - for describing the action of performing a procedure

The RelativeTime datatype can be used via the RelativeTime extension to define the timing of the action.

Timing Datatype Interpretation Modifications

This Implementation guide has a modified interpretation of the Timing datatype. Specifically, fields that have corresponding “Max” fields (count, duration, frequency, period) are now interpreted as minimum values. To specify an exact value, the base field and its corresponding Max field must be set to the same value.

These changes pertain to the following profiles / elements:

• RecommendationEligibilityCriteria.characteristic
• RecommendationAction
• RecommendationPlan.action

Changes to Timing Datatype

Examples

• Example 1: Exact number of Occurrences

  {
    "repeat": {
      "count": 2,
      "countMax": 2
    }
  }
  

  • This indicates the event should occur exactly 2 times.
• Example 2: Occurrences Range

  {
    "repeat": {
      "count": 2,
      "countMax": 5
    }
  }
  

  • This indicates the event should occur at least 2 times but no more than 5 times.
• Example 3: Minimal Duration

  {
    "repeat": {
      "duration": 1,
      "durationUnit": "h"
    }
  }
  

  • This indicates the event should last one or more hours.
• Example 4: Maximal duration

  {
    "repeat": {
      "durationMax": 2,
      "durationUnit": "h"
    }
  }
  

  • This indicates the event should last no more than two hours.

Implementation Notes

• Ensure that when setting the exact value, both the base field and its corresponding “Max” field are set to the same value.
• These changes aim to provide more flexibility and clarity in specifying the timing and frequency of events, ensuring that minimal and maximal constraints are clear to implementers.
