Profiles

This page provides an overview of all profiles defined in the NP Core Implementation Guide, grouped by clinical domain. Each profile is a constrained FHIR R4 resource tailored to the requirements of health information exchange in Nepal.

For the full definitions, see the Artifacts index.


Administrative

NP Core Patient

Profile: NPCorePatient
Parent: Patient

The central demographic profile for individuals receiving healthcare in Nepal. Key constraints:

  • Identifiers: Patient identifiers are sliced by identifier.system. identifier[healthId] (Nepal Health ID, issued by MoHFS) is required (1..1), while identifier[nationalId] (Nepal National ID, issued by DONIDCR) is supported and recommended but optional (0..1).

    Additional optional national-document identifiers are supported:

    • identifier[citizenshipNumber] (citizenship certificate, MoHA)
    • identifier[healthInsuranceId] (Health Insurance Board)
    • identifier[passportNumber] (Department of Passports, MoFA)
    • identifier[ssfNumber] (Social Security Fund)
  • Name: name is required (1..*). The invariant np-pat-1 is evaluated on each name independently and requires either a family name or a given name to be present, or else a Data Absent Reason extension to explain why the name is missing. A patient who uses a single name, and a patient carrying both an official name and a nickname, are both conformant.
  • Address: Restricted to NPCoreAddress.
  • Caste / Ethnicity: An optional extension (NPCoreCasteEthnicity) captures caste or ethnic group using the Nepal-specific ValueSet.
  • Other supported demographics: birthDate, gender, and telecom are all Must Support.

NP Core Practitioner

Profile: NPCorePractitioner
Parent: Practitioner

Profile for licensed health professionals practicing in Nepal. Key constraints:

  • Invariant np-prac-1 (required): A practitioner MUST carry at least one council registration identifier or an NHWR code. Six identifier slices are defined — one per national registration council, plus the national workforce registry:
    • nhwr - National Health Workforce Registry (NHWR) code, the umbrella national identifier maintained by MoHFS
    • nmc - Nepal Medical Council
    • nnc - Nepal Nursing Council
    • namc - Nepal Ayurveda Medical Council
    • nhpc - Nepal Health Professional Council
    • npc - Nepal Pharmacy Council

  • partOf is constrained to NPCoreOrganization, supporting organizational hierarchies.

NP Core Health Facility

Clinical Encounters

NP Core Encounter

Profile: NPCoreEncounter
Parent: Encounter

  • Identifier (required): identifier is mandatory (1..* MS). The invariant np-enc-1 requires at least one identifier whose system is namespaced under the assigning facility's NHFR code (i.e. http://nhfr.digitalhealth.gov.np/{nhfrCode}).
  • status and class are mandatory (1..1 Must Support).
  • subject is constrained to NPCorePatient or Group.

A grouping observation (panel) that references individual vital sign observations via hasMember. The panel LOINC code 85353-1 is mandatory (code.coding[VitalsPanelCode] is raised to 1..1; the base FHIR profile leaves it optional). hasMember (1..*) SHOULD reference the NP Core heart rate, body weight, body height, body temperature, blood pressure, or oxygen saturation observations where one applies, and SHALL otherwise reference an observation conforming to the base FHIR vital signs profile - so vital signs NP Core does not yet profile, such as respiratory rate, BMI and head circumference, can still be grouped.


NP Core Lab Report

Profile: NPCoreLabReport
Parent: DiagnosticReport

A diagnostic report for laboratory investigations.

  • category (1..*) is sliced with a mandatory lab slice fixed to LAB, so additional departmental or programme categories remain permitted alongside it.
  • code (1..1) is bound to the FHIR LOINC diagnostic report codes value set (report-codes) with extensible strength, so it SHALL carry a LOINC code naming the specific report, such as 11502-2 (Laboratory report) for a generic report or a panel code such as 58410-2 (CBC panel - Blood by Automated count). Use a single-analyte code only when the report covers exactly that one test; a non-LOINC code is permitted only where LOINC has no suitable concept.
  • subject, encounter, issued, and performer are all mandatory.
  • result (1..*) SHALL reference either NPCoreLabResultObservation or NPCoreLabPanelObservation.

NP Core Radiology Report

Profile: NPCoreRadiologyReport
Parent: DiagnosticReport

A diagnostic report for radiology (diagnostic imaging) investigations.

  • category (1..*) is sliced with a mandatory rad slice fixed to RAD, so additional departmental or programme categories remain permitted alongside it.
  • code (1..1) is bound to the FHIR LOINC diagnostic report codes value set (report-codes) with extensible strength, so it SHALL carry a LOINC code naming the specific study, such as 36643-5 (XR Chest 2 Views) or 24627-2 (CT Chest), falling back to 18748-4 (Diagnostic imaging study) only when the modality and body site are not known. A non-LOINC code is permitted only where LOINC has no suitable concept.
  • subject, encounter, issued, and performer are all mandatory.
  • resultsInterpreter (0..*) is the party who interpreted the imaging findings, typically a radiologist, and is recommended, with the same reference targets as performer.
  • imagingStudy (0..*) links the report to the underlying ImagingStudy when one is available.
  • result (0..*) SHALL reference NPCoreObservation when discrete imaging observations are recorded; radiology findings are more commonly conveyed narratively via conclusion, conclusionCode, or presentedForm.
  • specimen is not constrained, as specimens are not meaningful for imaging.

NP Core Lab Result Observation

  • requester restricted to practitioner or health facility.
  • performer restricted to NPCoreHealthFacility — the receiving facility.

Allergy and Intolerance

NP Core AllergyIntolerance

Records a patient's allergy or adverse reaction. patient is mandatory and constrained to NPCorePatient.


Documents

NP Core Clinical DocumentReference

Profile: NPCoreClinicalDocumentReference
Parent: DocumentReference

Represents a reference to a clinical document (e.g., discharge summary, operative note). The type element is bound (extensible) to the ClinicalDocumentTypeVS ValueSet.


Data Types

NP Core Address

Profile: NPCoreAddress
Parent: Address

A general-purpose datatype profile. Its base fields (line, city, district, state, postalCode, country) carry standard FHIR Address semantics and can represent an address in any country. country is required (1..1) and bound required to the ISO 3166-1 alpha-2 code list, so a Nepali address carries "NP" rather than "Nepal" or "NPL". R4 places no binding on Address.country, and without one the np-addr-1 comparison below would be a string match against free text.

When country is Nepal ("NP"), three additional coded extensions aligned to Nepal's federal administrative geography may be used, each paired with the corresponding human-readable Address field:

Extension Bound ValueSet Paired Address field
province (0..1 MS) NepalProvinceVS Address.state
district (0..1 MS) NepalDistrictVS Address.district
localLevel (0..1 MS) NepalLocalLevelVS Address.city

The invariant np-addr-1 enforces this: these three extensions SHALL only be present when country is "NP". An optional geolocation extension may be used to carry latitude and longitude for map-based workflows, independent of country.
