Applications of Telepathology • Surgical pathology • Primary diagnosis or consultation • Documentation of gross pathology • Consultation with clinicians • Autopsy pathology • Clinical pathology • Microbiology • Protein electrophoresis and immunofixation • Continuing education
Clinical Need for Telepathology at Iron Mountain VAMC • Retirement of pathologist • Surgical pathology (~1,000 cases per year) • Frozen sections • Autopsies (~10 per year) • Diagnostic Nuclear Medicine studies • (Service chief, clinical pathology) • Component of comprehensive telemedicine program

Technical Summary (first 2,200 cases) Deferral rate: ~2% Concordance on non-deferred cases: 99.7% Time per case: 11.6 min (cases 1-200), reduced to 3.58 min (cases 2001-2200) Time per slide: 4.25 min (cases 1-200), reduced to 1.13 min (cases 2001-2200) Case turn-around-time: < 1.5 days
Telepathology and the Autopsy • Send key images electronically to attending along with PAD • Submit tissue sections from a distance • Documentation of sections • Autopsy conference presentations • VistA Imaging as permanent record
Consolidation of Microbiology Functions • Plate, incubate and send (portable incubators) • Telepathology to view gram stains and early culture growth - primary lab • Telepathology to view gram stains and show cultures to clinicians - core lab
Conclusions • Telepathology can be extended to all areas of anatomic and clinical pathology • Multiple capabilities available • Must balance access, diagnostic accuracy and cost • Users must be flexible, but do not have to be computer experts • Strong support of telecommunications network is essential
