    - Cognition: If the patient has the cognitive capacity to use the device via the Brief Cognitive Assessment Tool (BCAT®) short form (LOINC 95872-8) 
    - Physical Functioning: If the patient is physically able to use the device via the 9-Hole Pegboard Dexterity Test (LOINC 83141-2) 
    - Vision: If the patient's visual capabilities are aligned with the device features via the Motor Free Visual Perception test (MFVP) (SNOMED-CT 396216003) 
    - Health Literacy: If the patient has the ability learn how to use the device via the BRIEF health literacy screening tool (LOINC 95866-0) 
    - Disability: If the patient has a disability that would need to be accommodated in the selection of a device via an indication in the patient’s demographic record of having a disability (ICD-10  Z73.6) 
- Documented observation of the patient’s usage of the requested device during an assessment that may influence the fulfillment of the device.  
    - Example: A patient at a long-term care facility uses a cane to complete a walking assessment (e.g., the Centers for Medicare &amp; Medicaid Services [CMS] Minimum Data Set [MDS] section GG items on walking distance) that is captured as observation data (via the derivedFrom data element within the PFE Use of Device profile). 
- Supporting information about the patient's goals that may influence fulfillment of the device request. 
    - Example: A patient at an inpatient rehabilitation facility has a goal of living independently at home after knee surgery, which requires limiting the range of motion of their knee. To support this goal, the physical therapist overseeing their rehab submits device requests for a knee brace that limits range of motion and a grabbing tool to help compensate for limited mobility due to the brace. Supporting information related to the goal can include: Independent daily dressing assessment (e.g., items GG0130.F and G from the MDS captured in the LOINC panel 108256-9) and a pain assessment (e.g., section J from the MDS captured in the LOINC panel 108256-9) that are completed by the patient while wearing a knee brace and while using a grabbing tool (captured in the PFE Goal profile via an Observation under the “addresses” data element). 
    - Example: A patient in a skilled nursing facility has a goal to gain weight and maintain it. The patient’s dietitian orders an enteral nutrition-related device. Supporting information related to the goal can include: Vital sign data regarding weight to assess gain/maintenance (captured in the PFE Goal profile via LOINC code 29463-7 under the “measure” data element), Nutrition orders (captured in the PFE Goal profile via a NutritionOrder under the “addresses” data element)"/>

There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference."/>
      <comment
               value="When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. 

When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference

Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference.  For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport).  One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any)."/>
