Bottom Line: However, presentation time was significantly less for WSI compared to MP as selection and annotation of slides was done prior to TPC with WSI, enabling more efficient use of TPC presentation time.Whole slide imaging, particularly with the ability to use oil scanning, provides higher quality images compared to MP and significantly increases clinician satisfaction.WSI streamlines preparation for TPC by permitting prior slide selection, resulting in greater efficiency during TPC presentation.

ABSTRACT

Background: Whole slide imaging (WSI) is widely used for education and research, but is increasingly being used to streamline clinical workflow. We present our experience with regard to satisfaction and time utilization using oil immersion WSI for presentation of blood/marrow aspirate smears, core biopsies, and tissue sections in hematology/oncology tumor board/treatment planning conferences (TPC).

Methods: Lymph nodes and bone marrow core biopsies were scanned at ×20 magnification and blood/marrow smears at 83X under oil immersion and uploaded to an online library with areas of interest to be displayed annotated digitally via web browser. Pathologist time required to prepare slides for scanning was compared to that required to prepare for microscope projection (MP). Time required to present cases during TPC was also compared. A 10-point evaluation survey was used to assess clinician satisfaction with each presentation method.

Results: There was no significant difference in hematopathologist preparation time between WSI and MP. However, presentation time was significantly less for WSI compared to MP as selection and annotation of slides was done prior to TPC with WSI, enabling more efficient use of TPC presentation time. Survey results showed a significant increase in satisfaction by clinical attendees with regard to image quality, efficiency of presentation of pertinent findings, aid in clinical decision-making, and overall satisfaction regarding pathology presentation. A majority of respondents also noted decreased motion sickness with WSI.

Conclusions: Whole slide imaging, particularly with the ability to use oil scanning, provides higher quality images compared to MP and significantly increases clinician satisfaction. WSI streamlines preparation for TPC by permitting prior slide selection, resulting in greater efficiency during TPC presentation.

Mentions: A total of 12 responses were received from 16 surveyed clinical attendees (75% response rate), who all reported significantly increased satisfaction with WSI in all categories evaluated on the survey (P < 0.01 in all categories) [Figure 4]. Furthermore, free-text feedback, received from attending hematologists, described overwhelmingly positive comments regarding WSI (“new system”) compared to MP (“old method”), including “the new system is superb: High resolution, focus on important areas of the slides, much faster and much more efficient than the old method. It will allow teleconferencing with outside doctors and as such promote outreach,” “The new system is awesome (the pathologist) was able to focus more on describing the slide, diagnostic work up (immunohistochemistry, etc.) rather than trying to find the area of interest in the slide looking into the microscope. I am very impressed with the new system.” Examples of screenshots comparing the image quality of WSI and MP for various slide types and tissues are shown in Figures 5–7. Selected photographs of the actual projected images on the overhead projector are shown in Figures 8-10. Seven respondents (58%) noted decreased motion sickness with WSI compared to MP, while five respondents (42%) reported not experiencing motion sickness with either modality.
