Digital whole slide imaging (WSI) is an emerging technology for pathology
interpretation, with specific challenges for dermatopathology, yet little is
known about pathologists' practice patterns or perceptions regarding WSI for
interpretation of melanocytic lesions. A national sample of pathologists
(N?=?207) was recruited from 864 invited pathologists from ten US states (CA, CT,
HI, IA, KY, LA, NJ, NM, UT, and WA). Pathologists who had interpreted melanocytic
lesions in the past year were surveyed in this cross-sectional study. The survey
included questions on pathologists' experience, WSI practice patterns and
perceptions using a 6-point Likert scale. Agreement was summarized with
descriptive statistics to characterize pathologists' use and perceptions of WSI.
The majority of participating pathologists were between 40 and 59 years of age
(62%) and not affiliated with an academic medical center (71%). Use of WSI was
seen more often among dermatopathologists and participants affiliated with an
academic medical center. Experience with WSI was reported by 41%, with the most
common type of use being for education and testing (CME, board exams, and
teaching in general, 71%), and clinical use at tumor boards and conferences
(44%). Most respondents (77%) agreed that accurate diagnoses can be made with
this technology, and 59% agreed that benefits of WSI outweigh concerns. However,
78% of pathologists reported that digital slides are too slow for routine
clinical interpretation. The respondents were equally split as to whether they
would like to adopt WSI (49%) or not (51%). The majority of pathologists who
interpret melanocytic lesions do not use WSI, but among pathologists who do, use
is largely for CME, licensure/board exams, and teaching. Positive perceptions
regarding WSI slightly outweigh negative perceptions. Understanding practice
patterns with WSI as dissemination advances may facilitate concordance of
perceptions with adoption of the technology.
