The Barcode-Driven Lab: Success in a Large System Rodney Schmidt, MD, PhD University of Washington, Seattle April 17, 2011 Place sub-brand here
Topics • Why create the barcode-driven lab? • Why in a large, complex lab? • Overview of functionality • Not the detailed “how”; workflow • Achieved benefits • Error reduction • FTE savings • Important factors in success • UCLA, Sierra Pathology, NWP, NYU, OHSU • What’s down the road?
Disclosure • Bar-coding software developed at UW (OmniTrax and OmniImage) has been licensed by UW to Pathway Pathology Consultants for PowerPath end-users. • Dr. Schmidt and his team have a revenue-sharing agreement with UW. • Dr. Schmidt has a consulting agreement with Thermo-Fisher for educational talks.
Expensive $23k/gross station $10k/cutting station Software Workspaces change Wiring, networking Time investment Software fast Workspaces slow Financing slow Processes change Material handling QA Jobs change Workflow Change management Pathologists affected! Why barcode? Who needs the hassle?!
Large Systems – Special Factors • Multiple locations • Trainees – Residents and Fellows • Personnel turnover • Outside materials (e.g. consults) • Ancillary testing • Higher fraction of complex cases Issues: Training, complexity, communication Need: Robust systems to help people do things right
Bringing Bar-coding to AP • Track slides (2005) • Eliminate the “lost slide” problem • Ease conference prep • Specimen labels (2006) • Tissue discards and tracking • Drive gross photography • Block creation and labeling (2008) • Automated JIT production of barcoded blocks • Gross room QA process and tracking • Slide creation and labeling (2008) • Automated JIT creation of barcoded slides • Facilitate workflow and QA • Eliminate all manual labeling (and errors) • Facilitate workflow – JIT information display
Material identification (2005) • Handwritten specimen labels • Manual, off-line cassette labeling • Hand-written slide labels
Targets – Gross Room • Foolproof labeling • No human labeling/data entry • Reduced dependence on support staff • Off-hours availability • Redirection of support personnel • Reduced waste of cassettes • Grossing step at least as fast as current • (Record timestamps) The unsupervised Resident!
Receive specimen and enter data into the LIS Generate a bar coded label for the specimen and laboratory request form. Minimum extra keystrokes (one) Targets - Accession
Classic Grossing Workflow Accession specimens Label specimens * Label cassettes * Group with specimens * Move to staging area Move to gross bench * Lay out cassettes * Fill cassettes Request more cassettes Store excess with specs Handling steps Rack filled cassettes Possible errors * * Reconcile with LIS Transport for processing * QA steps
Accession specimens Bar-code specimens Scan/print cassettes * Lay out cassettes * Fill cassettes Rack filled cassettes * * Transport for processing Just-in-Time Printing Fewer handling steps Fewer (1) error opportunities Fewer QA processes Rescan cassettes Courtesy General Data
Benefits • Efficiency • No manual pre-printing and sorting of cassettes • Quick just-in-time additional cassettes • Default cassettes from PowerPath specimen panels • Blocks automatically ordered in PowerPath • Quality • No manual labeling (no errors) • Scanning specimen barcode assures correct specimen • Enter cutting instructions, # pieces • Records which blocks are sent for processing
Histology – Embedding • Target • View critical information about block and specimen • Efficient workflow • Block scan: • Embedding instructions • Number of pieces of tissue • Specimen info • (Record timestamps)
Histology – Cutting • Targets • Present critical information (block, specimen) • Eliminate manual slide labeling • Block/slide verification • Multiple workflows • No clutter • Efficient • Touch-screens; no keyboards • Block scan: • JIT slide printing/labeling • Info display • Slide scan: • Block/slide match
Cutting - Benefits • Elimination of hand labeling • Much faster than manual labeling for blocks with many slides • Fewer block/slide mismatches • Overall throughput increased ~10%
Slide Life Cycle Histology Pathology Offices Sendouts Faculty signout File Pull for conference Resident review Histology work order completes with scanning Deliver Ship
Slides – Benefits • Less staff time looking for slides • Faster to find last location than make a phone call • Fewer arguments over whether slides were delivered • Fewer recuts? • Improved job satisfaction • ** Saved me 30 min the first day! ** • Overall savings > 2.0 FTE!

Barcoding Benefits • Direct personnel (FTE) • 2.0 Slide delivery and tracking • 0.75 Cassette printing • 0.1 Specimen discards • 0.1 Document scanning • TBD Fluorescence image import ~$150,000/yr assuming $50,000/FTE
Barcoding Benefits • Indirect personnel (FTE) • 0.5 Scanned consult document availability1 • TBD Scanned Req forms • TBD Slide location info (e.g. Pathologists) • Reduced loss of materials • Slide/Block tracking • Specimen discards 1Schmidt, RA, et al. Am J Clin Pathol 126:678-83, 2006
Barcoding Benefits Error Reduction • Elimination of all manual labeling steps! • Reduced labeling errors • Specimens • Blocks • ~988/yr to near 0 • “How did you manage to do that?!” • Slides • Gross photos • Scanned documents • Photomicrographs
Reasons for Success • Optimized workflow • Lean analysis • Close ties to users • Multiple workflows; exception trapping • LIS interoperability • Initially with PowerPath; now general • Just-in-time production of materials • Selection of appropriate equipment
Where Next? • Specimen transport • Within multiple sites in a large lab • Upstream all the way from the patient • Result transport • All the way back to the patient • Likely to need multiple systems Need an industry barcode standard
Where Next? • Tissue banking (becoming routine) • Unique identifiers (encrypted for research) • Repository management • Maintain provenance • Pre-analytic variables • Tissue micro-arrays • Each sample linked back to patient
Where Next? Patient- and time-based disease data structures (Time) Treatment 1 Treatment 2 Patient Diagnosis Persistent Recurrence • All types of data • IHC • Cytogenetic • Molecular • Links between serial samples of same disease • Relation to clinical treatment • Correlated blood samples What does sample tracking mean for molecular testing?
Conclusion • Barcoding is becoming an expectation • Patient safety / error reduction • It’s to your financial advantage For success, you must be sophisticated enough to know the difference between just putting a barcode on something and having a barcode-driven lab.

Achieved Benefits • Marked reduction in labeling errors • Improved inventory control (i.e. knowledge of where things are) • Direct savings of ~ 3 FTE • Indirect savings of >> 0.5 FTE • Improved image collection and management (paperwork, gross, micro, EMs, IF, etc) • Increased job satisfaction
