“…. Incorrect patient identification was involved in 13% of surgical errors and 67% of transfusion errors.” How well do we do in Pathology?
Understanding Workflow Histology laboratories have a very standardized workflow which mainly varies in the degree of automation, layout and work schedules rather then process steps Accessioning Administration Quality Assurance Case Record Creation Complex / Small Tissue Sample Examination Grossing Tissue Processing and Embedding Tissue Cutting Cutting and Sorting Slide Sorting Special Staining IHC Staining ISH Staining H&E Staining Staining Sorting Slide Sorting (to Patient Cases) Screening & Interpretation Pathologist Slide Reviewing No Further Testing Required Reruns or Additional Testing Required Archiving Blocks and Slides to Storage

Three Pillars RightPatient RightTreatment Right Diagnosis
Integration of processes through the entire pathology laboratory eliminates steps that might introduce errors. Specimen in the right block? Number on Block? Correct Registration? Will the right specimen follow the right patient record? Is Data Registration done correctly? Right Sample? Correct Registration? Right specimen to slide? Right label? Right Data Reg.? Operating Room Right Patient? Correct Registration? Right Fixation Right Label? Right Staining? Right Reagent? Right Protocol? Concentration? Right Buffer? Correct Reg.? Right Label? Right Storage and Retrieval? Correct Diagnosis? Virtual Feedback? Right Patient?

Barcoding verses Keyboard Entry • Ohio University study found: • That a well-trained data entry operator makes a data entry error 1 in every 300 keystrokes. • Scanning a code 128 linear barcode produces 1 error in 2.8 million (worst case) and 1 error in 37 million (best case). • Scanning a Datamatrix 2D code produces 1 error in 10.5 million (worst case) and 1 error in 612.9 million (best case).
