We received a recommendation to add a “Diagnosis” QDM datatype into our existing hospice definition. The recommendation was to use the SNOMED CT finding codes listed below that currently already resided in "Hospice Care Ambulatory" value set (OID: 2.16.840.1.113883.3.526.3.1584) and mapped to "Intervention, Performed" and "Intervention, Order"). We plan to strip out these finding codes from the "Hospice Care Ambulatory" value set (OID: 2.16.840.1.113883.3.526.3.1584) and create a new stand-alone value set to include them within. We are looking to consolidate feedback from implementors to see if this would be appropriate to capture patients in hospice care in an EHR.   

• 170935008, Full care by hospice (finding)
• 170936009, Shared care - hospice and general practitioner (finding)
• 305911006, Seen in hospice (finding)

Current expression:
   exists ( ["Encounter, Performed": "Encounter Inpatient"] InpatientEncounter
     where ( InpatientEncounter.dischargeDisposition ~ "Discharge to home for hospice care (procedure)"
          or InpatientEncounter.dischargeDisposition ~ "Discharge to healthcare facility for hospice care (procedure)"
      )
         and InpatientEncounter.relevantPeriod ends during day of "Measurement Period"
   )
     or exists ( ["Encounter, Performed": "Hospice Encounter"] HospiceEncounter
         where HospiceEncounter.relevantPeriod overlaps "Measurement Period"
     )
     or exists ( ["Assessment, Performed": "Hospice care [Minimum Data Set]"] HospiceAssessment
        where HospiceAssessment.result ~ "Yes (qualifier value)"
            and Global."NormalizeInterval" ( HospiceAssessment.relevantDatetime, HospiceAssessment.relevantPeriod ) overlaps "Measurement Period"
     )
    or exists ( ["Intervention, Order": "Hospice Care Ambulatory"] HospiceOrder
         where HospiceOrder.authorDatetime during day of "Measurement Period"
     )

    or exists ( ["Intervention, Performed": "Hospice Care Ambulatory"] HospicePerformed
        where Global."NormalizeInterval" ( HospicePerformed.relevantDatetime, HospicePerformed.relevantPeriod ) overlaps "Measurement Period"
   )
 

The question for the User Group is whether it is reasonable to add to the expression the QDM datatype "Diagnosis" with a value set containing SNOMED findings indicating hospice care
