Pathology diagnostic report aggregating all biopsy-derived observations for prostate cancer registration (Anmälan). This profile is the first DiagnosticReport profile in the NPCR profile set, differing from the 20 existing Observation/Procedure/Condition/ServiceRequest/Encounter/Patient profiles by grouping multiple observations under a single pathology report instance.

Source variables covered (4 NPCR Variabelbeskrivning variables):

• D_PrepNr → .identifier.value (PAD/CYT-nr, text business identifier)
• D_PrepAr → .effective[x] (dateTime, year precision representing Preparatår — the year the specimen was registered at the pathology lab)
• D_PatCytLista → .performer (Reference to Organization; Organization.name carries the pathology department name per NPCR Värdedomän)
• D_PatCytKod → .performer (Reference to Organization; Organization.identifier.value carries the pathology department code)

Note on D_PatCytAvd exclusion: The NPCR variable D_PatCytAvd (free-text pathology department name) has Teknisk giltighetstid 2025-09-30, i.e., it was deprecated in September 2025 per the Variabelbeskrivning changelog ("AH 20250930: Sätter ett slutdatum. Finns inte i koden längre."). This profile reflects the post-deprecation state and does not map D_PatCytAvd.

Aggregation design .result references: .result uses FHIR's multiple-targetProfile pattern to reference any of 9 NPCR Observation profiles that can be derived from a pathology specimen: 3 BiopsyResults profiles (Targeted, Systematic, Unclear), 5 Gleason profiles (Summary, Targeted, Systematic, Unclear, TURP/Cysto), and WHOGrade. This creates the first explicit inter-profile dependency in the NPCR profile set, representing NPCR's "one-report → many-observations" clinical model.

Design rationale .code binding (documentation gap fallback): FHIR R4 mandates DiagnosticReport.code (1..1), but NPCR documentation does not specify a terminology binding for pathology report identification. This profile applies LOINC 60568-3 "Pathology synoptic report" as an internationally recognized, domain-appropriate fallback. This pattern, bridging NPCR documentation gaps with FHIR-recommended terminology, is consistent with other NPCR profiles in this set (e.g., Observation.category using FHIR observation-category CodeSystem).

Design rationale .category binding: .category uses HL7 v2 Table 0074 (Diagnostic Service Section ID) code "PAT" (Pathology), which is FHIR R4's default CodeSystem for the diagnostic-service-sections ValueSet bound to DiagnosticReport.category.

Design rationale radiology/pathology asymmetry (Discussion finding): The NPCR profile set currently includes this pathology DiagnosticReport profile but no corresponding radiology DiagnosticReport profile, because NPCR captures explicit pathology report metadata (PAD/CYT-nr, Preparatår, Patologavdelning) enabling report-level aggregation, whereas no analogous radiology report metadata exists in NPCR Anmälan (only D_MRdatum, insufficient for report identification). This asymmetry is a documented feasibility finding.

Conditional requirements (per NPCR Beteende/logik) — documented but not enforced:

• D_PrepNr, D_PrepAr, D_PatCytLista are obligatoriskt when D_Diagr != 1 (i.e., when diagnosis involves pathology)
• D_PatCytKod is obligatoriskt for monitors when D_Diagr != 1
