A study assessing the feasibility and diagnostic accuracy of real-time teledermatopathology

摘要

Dermatopathology represents the gold standard for the diagnosis of skin diseases and neoplasms that cannot be diagnosed on clinical grounds alone. The aim of this study was to test the feasibility and to assess the accuracy of an Internet-based real-time (live) teledermatopathology consultation. Twenty teaching cases and 10 randomly selected routine cases were presented to four expert dermatopathologists, first by real-time teledermatopathology and, subsequently, in a blinded fashion, using light microscopy. Throughout the study the overall diagnostic accuracy did not differ for the two methods. However, the mean level of confidence and the mean observation times differed significantly between real-time teledermatopathology and light microscopy (92.6±0.24% versus 99.5±0.02%, and 96.31±11.55 sec versus 25.47±3.85 sec, respectively). Assessment of routine cases did not produce significant diagnostic differences between the two methods. These results prove that real-time teledermatopathology offers an affordable and technically simple technology that lends itself to training as well as to diagnosis of lesions from routine practice by experts situated at remote sites.
