  2. Overview • Intra hospital integration profiles • Anatomic Pathology Workflow (APW) • Ordering and performing anatomic pathology examinations • Community • Anatomic Reporting for Public Health (ARPH) • Sending anatomic pathology reports to public health organizations • Anatomic Pathology Structured Report (APSR) • Sharing/exchanging structured anatomic pathology reports as CDA documents

  3. Organization of Anatomic Pathology Technical Framework 2011 2010 Revision 2.0 July 23, 2010Draft for Trial Implementation 2010 Supplement for Trial Implementation

  4. Anatomic Pathology Workflow (APW) • Establishes the integrity of basic pathology data acquired for examinations being ordered for an identified patient • Defines the actors and transactions involved in • Ordering and reporting aspects of the workflow • Order entry, report creation and transmission. • Imaging aspects of the workflow • Image acquisition, storage and distribution among multiple systems.

  9. Test casesSpecimen model : Usual situation Specimen can be identified by containers’ ID Gross imaging Virtual slide

  10. Test cases Unusual situation: Tissue Micro Array • More than one derived specimen on slide coming from the different blocks coming from different parts and from different patients

  11. Anatomic Pathology Reporting to Public Health (ARPH) • Joint initiative : IHE AP, HL7 AP, NAACCR (North American Association of Central Cancer Registries), CDC (Centers for Disease Control). • Defines the actors and transactions involved in anatomic pathology reporting to public health organizations. • Global Perspective of Cancer Surveillance • International Association of Cancer Registries • 241 Registries (Voting Member) from all 6 continents • North American Association of Central Cancer Registries • All Canadian Provinces • All US States • All US Territories and Jurisdictions

  14. Standards used • HL7 v2.5 • ORU^R01 message (PAT-10) • LOINC • SNOMED CT • NAACCR* • Standards for Cancer Registries Volume V: Pathology Laboratory Electronic Reporting v3.0 • Search Term List • International Classification of Diseases, 10th rev (and 9th rev) *NAACCR - North American Association of Central Cancer Registries (www.naaccr.org)

  15. Anatomic Pathology Structured Report (APSR) • Joint IHE and HL7 anatomic pathology initiative • Content integration profile standardizing Anatomic Pathology Structured Report (APSR) using HL7 CDA • APSR as CDA documents including Anatomic Pathology observations bound to images or regions of interest • Shared or exchanged within a community of care providers using existing integration profiles defined by IHE Information Technology Infrastructure • Unique opportunity to share/exchange Anatomic Pathology Structured Reports that are semantically interoperable at an international level

  16. Scope • APSR for surgical pathology • 22 CDA templates • Generic APSR template • All fields of anatomic pathology (inflammatory, vascular, traumatic, metabolic diseases as well as cancer) • Generic cancer APSR template • 20 organ-specific cancer APSR templates • “Traditional” anatomic pathology observation using light microscopy (including immunohistochemistry, FISH, etc) • Further cycles • Forensic (autopsy, toxicology) • Special ancillary techniques (flow cytometry, cytogenetics, electronic microscopy) • Research (TMA, etc)

  17. BackgroundFrom clinical document models… • Recent recommendations for required, preferred, and optional elements for any APR of surgical pathology, regardless of report types [Goldsmith 08] • National initiatives • Anatomic Pathology SR (Netherlands, Germany, Australasia) • Cancer APSR • US - CAP (College of American Pathologists) • 67 cancer checklists and protocols (October 2009) • France - SFP (French society of pathology) – INCa (French National Cancer Institute) • Minimum data sets for cancer APSR in 20 locations (85% of new cancers in France) (required by accrediting bodies) • Australasia • 6 templates for cancer APSR • UK Royal college Goldsmith, J.D., et al., Reporting guidelines for clinical laboratory reports in surgical pathology. Arch Pathol Lab Med, 2008. 132(10): p. 1608-16.

  18. Background … to IT templates • Non healthcare IT standard • CAP electronic Cancer Checklist • Healthcare IT standard • CEN archetypes • Australia • HL7 CDA • Most reliable standard for clinical document templates • Existing implementation guides for the APSR ? • Netherlands, Germany

  20. APSR actors & transactions • Content (Anatomic Pathology Structured Report) is created by a Content Creator consumed by a Content Consumer. • Sharing or transmission of content from one actor to the other • XDS, XDM and XDR Integration Profiles, described in Volume 3 of the Anatomic Pathology Technical Framework.

  21. CDA Document Content Module (n=22) Any APSR CDA document content module is composed of a header and a structured body. • 3 types of CDA Document Content Modules • Generic APSR (1.3.6.1.4.1.19376.1.8.1.1.1) • Generic Cancer APSR (1.3.6.1.4.1.19376.1.8.1.1.2) • 20 organ-specific cancer APSR
