Comparison of the diagnostic utility of digital pathology systems for telemicrobiology

Abstract

Introduction:Telemicrobiology is a growing component of clinical microbiology informatics. However, few studies have been performed to assess the diagnostic utility of telemicroscopy systems in evaluating infectious agents.Objective:Evaluate multiple contemporary digital pathology platforms for use in diagnostic telemicrobiology.Materials and Methods:A mix of thirty cases that included viral, bacterial, fungal, and parasitological findings were evaluated by four experts using ×40 whole slide imaging (WSI) scans, ×83 oil-immersion WSI scans, ×100 oil-immersion WSI scans, digital photomicrographs, and glass slides.Results:The ×83 WSI, ×100 WSI, and photomicrograph interpretations were not significantly different in quality and accuracy when compared to glass slide interpretations. The ×40 WSI interpretations were of lower quality and were more likely to be incorrect when compared to glass slide interpretations.Conclusions:In this study, high magnification, oil-immersion digital pathology platforms are better suited to support telemicrobiology applications and yield interpretations on par with glass slide evaluations.

Experience Reviewing Digital Pap Tests using a Gallery of Images

“…Including microorganisms within the gallery of diagnostic images therefore allows the additive capability to screen for specific organisms. Further, unlike prior digital pathology systems that have had major limitations with the diagnosis of microorganisms,[ 20 ] images acquired with the Hologic scanner were of satisfactory quality to permit the identification of several organisms.…”

“…Similarly, confirmation of microorganisms digitally requires higher resolution digital images or scanning at multiple z-levels. [ 47 ]…”

The Use of Screencasts with Embedded Whole-Slide Scans and Hyperlinks to Teach Anatomic Pathology in a Supervised Digital Environment

“…Multiple studies in our laboratory and others have shown that similar diagnoses can be obtained using digital and light microscopy and that digital microscopy can be effectively used for primary surgical pathology diagnosis, telepathology, teaching, and other applications. [222324252627282930] Digital pathology systems offer a variety of logistical advantages, as they can streamline the flow and storage of cases, help reduce clerical errors, shorten turnaround time, and provide other operational efficiencies. These have stimulated an increasing interest in using them to replace the time-tested method of distributing glass slides throughout a laboratory for examination with light microscopes.…”
