FHIR Resources Used

Instructions

Step 1: Retrieve Patient Resource

Tool: fhir_read
resourceType: "Patient"
id: "[patient-id]"

Extract the following fields:

• Identifiers: MRN (identifier where type.coding.code = "MR"), SSN (last 4 only), driver's license
• Name: name array -- use name.use = "official" as primary; note maiden names (use = "maiden")
• Birth Date: birthDate (calculate age)
• Gender: gender (administrative gender)
• Race/Ethnicity: US Core extensions at extension where URL = http://hl7.org/fhir/us/core/StructureDefinition/us-core-race and http://hl7.org/fhir/us/core/StructureDefinition/us-core-ethnicity
• Address: address array -- identify use = "home" vs "work" vs "temp"
• Telecom: telecom array -- phone (system = "phone"), email (system = "email"), fax
• Preferred Language: communication array where preferred = true
• Marital Status: maritalStatus
• Deceased: deceasedBoolean or deceasedDateTime
• Managing Organization: managingOrganization

Step 2: Retrieve Emergency Contacts and Related Persons

Tool: fhir_search
resourceType: "RelatedPerson"
queryParams: "patient=[patient-id]"

For each RelatedPerson:

• Extract name, relationship type (relationship.coding.code), phone, email
• Check period to confirm the relationship is current (no end date or end > today)
• Identify relationship roles: emergency contact, next of kin, guarantor, power of attorney

Step 3: Retrieve Insurance Coverage

Tool: fhir_search
resourceType: "Coverage"
queryParams: "patient=[patient-id]&status=active"

For each active Coverage:

• Plan name from class where type.coding.code = "plan"
• Group number from class where type.coding.code = "group"
• Subscriber ID from subscriberId
• Payor organization from payor reference
• Coverage period from period
• Coverage order (order field: 1 = primary, 2 = secondary)

Step 4: Check for Advance Directives

Tool: fhir_search
resourceType: "Consent"
queryParams: "patient=[patient-id]&category=http://terminology.hl7.org/CodeSystem/consentcategorycodes|acd"

If no results, also search:

Tool: fhir_search
resourceType: "DocumentReference"
queryParams: "patient=[patient-id]&type=http://loinc.org|64298-3"

LOINC 64298-3 = Power of attorney / Advance directive

Step 5: Flag Missing Critical Data

Scan the collected data and flag any of the following as missing:

• No emergency contact (zero RelatedPerson resources or none with emergency contact relationship)
• No active insurance coverage
• No preferred language specified
• No allergy documentation status (check if AllergyIntolerance search returns zero results -- this indicates allergies have not been reviewed, not that there are none)
• No advance directive on file
• Missing phone number or email
• Missing address

Troubleshooting

No Patient Resource Found

• Verify the patient ID is correct. Try searching by name and DOB instead:

  Tool: fhir_search
  resourceType: "Patient"
  queryParams: "family=[lastname]&given=[firstname]&birthdate=[YYYY-MM-DD]"
  

• Check if the ID format matches the FHIR server's expectations (some use UUIDs, others use numeric IDs).

RelatedPerson Search Returns Empty But Patient Has Emergency Contact in Record

• Some EHR systems store emergency contacts as extensions on the Patient resource rather than as separate RelatedPerson resources. Check Patient.contact array for embedded contact entries:

  Patient.contact[].relationship
  Patient.contact[].name
  Patient.contact[].telecom
  

• EPIC systems often use the Patient.contact array instead of RelatedPerson resources.

Coverage Resources Missing Plan Details

• The class array may use different type codes depending on the payer. Check for type.coding.code values: "plan", "group", "subplan", "subgroup", "rxbin", "rxpcn".
• Some systems populate plan details in the payor referenced Organization resource. Follow the reference with fhir_read on the Organization.
