Definition / general
  • This topic discusses data analysis, billing and other subjects related to surgical pathology not described elsewhere in the informatics chapter
  • See also: Barcoding and tracking
Essential features
  • Specific applications of informatics in surgical pathology include
    • Barcode and radio frequency identification (RFID) scanning data applications for specimen tracking and quality management
    • Digital imaging and virtual microscopy
    • Telepathology and remote consultation
    • Laboratory information systems (LISs) and interface with electronic health record (EHR)
    • Applications in quality and error reduction
    • Applications for billing data
Terminology
  • Radio frequency identification (RFID)
  • Digital workflow
  • Whole slide imaging (WSI)
  • Anatomical pathology laboratory information system (APLIS)
  • Quality assurance (QA)
Applications
Collection and analysis of data for quality management applications
  • Crowdsource the collection of quality issues occurring throughout the testing process across all sites and all staff by linking a structured data set of potential problems to the LIS
  • By automating the collection of the patient and case context in the LIS when inputting a quality issue, issue entry is simplified and encouraged; linking this context to a quality issue enabled queries into data contained in the LIS for root cause analysis and quality improvement
  • Structuring the issue input enables counting and trending issues over time; computers can be made to identify significant changes in issue trends for better or worse and alert staff to the change
  • Associating quality issues with cost, delay and risk can give insight into significance of an issue beyond simple frequency
    Quality assurance tracker

    Quality assurance tracker


  • Informatics tools for ensuring quality and error reduction in anatomic pathology (Clin Lab Med 2008;28:207)
    • Preanalytical (e.g., surgical pathology specimen tracking)
      • Ensure where a specimen is within the workflow at a specific point in time, learn how long the specimen spends in a given process and identify bottlenecks within the workflow
    • Analytical (e.g., applying statistical quality control to immunohistochemistry through digital imaging)
      • Quantitation of test kit controls using image analysis
      • Application of common laboratory control methods to the results
      • Establishing quantifiable acceptable limits for control results to monitor variability between runs and detect process errors
    • Postanalytical (e.g., results reporting)
      • Ensure that all results from LIS reach their respective repositories
      • Detect, correct and resend any filing errors within 24 hours
      • Reduce the number of filing errors to within a 6 sigma standard

Applications of laboratory information systems (LISs) in surgical pathology (Arch Pathol Lab Med 2015;139:319)
  • Designed to meet workflow requirements in the laboratory and interface with electronic health record (EHR) and billing systems
  • Anatomic pathology LIS handles workflows related to surgical specimens
    • Patient identification
      • Unique patient identifiers allow LIS to transmit patient data across multiple institutions, personal health records or state and federal registries for mandatory reporting
    • Splitting samples
      • Tracking requirements for dividing specimens between anatomic pathology (AP) and clinical pathology (CP)
    • Ordering procedures for anatomical pathology (AP) orders entered in operating rooms (e.g., resections), surgery centers (e.g., endoscopies) and outpatient clinics
      • Appropriate clinical information accompanies the specimen electronically to facilitate pathologist sign out
    • Frozen section workflow in operating room
      • Electronic order is created in the EHR and processed by the LIS either before or after specimen delivery, with or without an already existing specimen
    • Specimen type in order interface
      • Determined by the specimen type assigned for each part received
      • Results in the number of cassettes printed and fee codes submitted
      Complex items that may be required in AP orders

      Complex items that may be required in AP orders


    • AP results in the EHR
      • Accessible and interpretable by clinicians
      • Can be sent to the physician's office for an outreach specimen
      • Either unstructured free text (with or without formatting and images) or in PDF format
      • Display supported by EHR
      • Linked with a test order
      • Can be amended (i.e., new report clearly replaces the existing report and not displayed as a second report)

Applications for billing data in surgical pathology
  • Each surgical pathology specimen has a discrete Common Procedural Terminology (CPT) billing code indicating the complexity of the evaluation of that specimen
  • These are 5 digit CPT codes the begin with 883??, ranging from a gross examination only code of 88300 to a comprehensive consultation core of 88325
  • Each of these billing codes is associated with a relative value unit (RVU) to correspond the complexity of the CPT code
  • Charting the complexity of the specimen billing codes can bring insight into the diversity of the caseload in a pathology practice
  • A different set of CPT codes can be used to reflect on the discretionary test ordering patterns for stains
    CPT codes for various specimen types and the associated RVU

  • When combining the specimen CPT codes with the discretionary staining CPT codes, a chart can show how stain ordering practices can be similar or vary greatly between pathologists
    • This type of analysis can be used to identify whether or not a standard of care or a care gap exists in a peer group

Value of structured AP data (Pathol Lab Med Int 2015;7:11)
  • Synoptic reporting in surgical pathology is a process for reporting specific data elements in a specific format based on cancer protocols
  • Ensures:
    • Completeness, timeliness, accuracy and clarity
      • Follow guidelines published by pathology associations
      • For pathologists
        • Ease of creating report using format required by the College of American Pathologists (CAP) Laboratory Accreditation Program (LAP) checklist
        • Inter and intrainstitutional collaborative clinicopathologic efforts
      • For clinicians
        • Accurate extraction of relevant information
        • Permits rapid use of prognostic systems for patient therapy
    • Scalability of data capture, interoperability and exchange
      • For researchers and cancer registrars
        • Raw data available within hours after report is released
        • Allows digital extraction and categorization
        • Use of natural language search modalities
  • Advantages of web based synoptic user interface:
    • Ordering ancillary studies
    • Utilizing diagnostic algorithms
    • Quality assurance
    • Creating pathology reports through automation with web based reporting systems with ability to populate data from ancillary studies, such as genomic data
