Consultation on urological specimens from referred cancer patients using real-time digital microscopy: Optimizing the workflow

[Current developments on digitalization : Analysis of quality and economics in healthcare]

Hintergrund

Im deutschen Gesundheitssystem und damit auch im Fachgebiet der Urologie gewinnen ökonomische Rahmenbedingungen zunehmend an Bedeutung und parallel dazu werden digitale Anwendungen vermehrt eingesetzt.

Fragestellung

Die Fragestellung betrifft die gesundheitsökonomische Auseinandersetzung mit den Rahmenbedingungen der Digitalisierung im deutschen Gesundheitssystem sowie ausgewählter Anwendungsbereiche in der Urologie.

Material und Methoden

Das Gutachten des Sachverständigenrates zur Begutachtung der Entwicklung im Gesundheitswesen (SVR) wird analysiert und eine systematische Literaturanalyse zum Einsatz der strukturierten Befundung und Analyse ausgewählter Literatur zu telemedizinischen Anwendungen in der Urologie unter gesundheitsökonomischen Gesichtspunkten durchgeführt.

Ergebnisse

Als zentrale Hemmnisse bei der Digitalisierung des deutschen Gesundheitswesens identifiziert der SVR dessen Regulierung und Komplexität sowie den Umgang mit Datenschutz und -sicherheit. Der Einsatz strukturierter Befundung kann Qualität, Effektivität und Effizienz der Befundung in der Urologie steigern. Im Hinblick auf die Kosten können signifikante Einsparungen mit zunehmender Digitalisierung in der Medizin realisiert werden.

Schlussfolgerungen

Aus medizinischer und gesundheitsökonomischer Perspektive besteht bei der Ausgestaltung von Rahmenbedingungen für digitale Anwendungen im deutschen Gesundheitssystem hinsichtlich der Informationssicherheit und des Datenschutzes weiterer Gestaltungsbedarf. Bei zielgerichtetem Einsatz von digitalen Anwendungen wie der strukturierten Befundung und der Telemedizin können optimale Voraussetzungen für den zunehmenden Einsatz von künstlicher Intelligenz im Fachgebiet der Urologie geschaffen werden.

The histopathological diagnosis of atypical meningioma: glass slide versus whole slide imaging for grading assessment

Limited studies on whole slide imaging (WSI) in surgical neuropathology reported a perceived limitation in the recognition of mitoses. This study analyzed and compared the inter- and intra-observer concordance for atypical meningioma, using glass slides and WSI. Two neuropathologists and two residents assessed the histopathological features of 35 meningiomas-originally diagnosed as atypical-in a representative glass slide and corresponding WSI. For each histological parameter and final diagnosis, we calculated the inter- and intra-observer concordance in the two viewing modes and the predictive accuracy on recurrence. The concordance rates for atypical meningioma on glass slides and on WSI were 54% and 60% among four observers and 63% and 74% between two neuropathologists. The inter-observer agreement was higher using WSI than with glass slides for all parameters, with the exception of high mitotic index. For all histological features, we found median intra-observer concordance of ≥ 79% and similar predictive accuracy for recurrence between the two viewing modes. The higher concordance for atypical meningioma using WSI than with glass slides and the similar predictive accuracy for recurrence in the two modalities suggest that atypical meningioma may be safely diagnosed using WSI.

Digital pathology in the time of corona

The 2020 COVID-19 crisis has had and will have many implications for healthcare, including pathology. Rising number of infections create staffing shortages and other hospital departments might require pathology employees to fill more urgent positions. Furthermore, lockdown measures and social distancing cause many people to work from home. During this crisis, it became clearer than ever what an asset digital diagnostics is to keep pathologists, residents, molecular biologists and pathology assistants engaged in the diagnostic process, allowing social distancing and a ‘need to be there’ on-the-premises policy, while working effectively from home. This paper provides an overview of our way of working during the 2020 COVID-19 crisis with emphasis on the virtues of digital pathology.

Being fully digital: perspective of a Dutch academic pathology laboratory

The introduction of fast and robust whole slide scanners has facilitated the implementation of ‘digital pathology’ with various uses, the final challenge being full digital diagnostics. In this article, we describe the implementation process of a fully digital workflow for primary diagnostics in 2015 at the University Medical Centre in Utrecht, The Netherlands, as one of the first laboratories going fully digital with a future‐proof complete digital archive. Furthermore, we evaluated the experience of the first 2 years of working with the system by pathologists and residents. The system was successfully implemented in 6 months, including a European tender procedure. Most pathologists and residents had high confidence in working fully digitally, the expertise areas lagging behind being paediatrics, haematopathology, and neuropathology. Reported limitations concerned recognition of microorganisms and mitoses. Neither the age of respondents nor the number of years of pathology experience was correlated with the confidence level regarding digital diagnostics. The ergonomics of digital diagnostics were better than those of traditional microscopy. In this article, we describe our experiences in implementing our fully digital primary diagnostics workflow, describing in depth the implementation steps undertaken, the interlocking components that are required for a fully functional digital pathology system (laboratory management, hospital information systems, data storage, and whole slide scanners), and the changes required in workflow and slide production.

Current use of telehealth in urology: a review

PURPOSE

Applications of telehealth have been growing in popularity. However, there is little information on how telehealth is being used in Urology. In this review, we examine current applications of telehealth in urological practices as well as barriers to implementation.

METHODS

A review was conducted of original research within the past 10 years describing telehealth applications in urology. Articles on telehealth as applied to other specialties were reviewed for discussion on real or perceived barriers to implementation.

RESULTS

Twenty-four articles met the inclusion criteria. The most common application of telehealth was using a video visit to assess or follow-up with patients. The second most commonly described applications of telehealth were telementorship, or the use of telehealth technology to help train providers, and telemedicine used in diagnostics. Studies consistently stated the effectiveness of the telehealth applications and the high level of patient and provider satisfaction.

CONCLUSIONS

Telehealth is sparingly used in urology. Barriers to implementation include technological literacy, reimbursement uncertainties, and resistance to change in workflow. When used, telehealth technologies are shown to be safe, effective, and satisfactory for patients and providers. Further investigation is necessary to determine the efficacy of telehealth applications.

A small-scale experimental study of breast FNA consultation on the internet using Panoptiq

INTRODUCTION

To test the potential for cytopathology consultation using Panoptiq (ViewsIQ, Richmond, BC, Canada; this is a new type of whole-slide image that is made manually and incorporates video content), we investigated its application in the cytopathological diagnosis of cases that were difficult to diagnose by breast fine-needle aspiration (FNA).

MATERIALS AND METHODS

Panoptiq files were created from liquid-based cytology slides prepared by the BD CytoRich Red (BD, Franklin Lakes, NJ) method. The slides were prepared from 23 consecutive samples of breast FNA that had been diagnosed as atypical or suspicious by the Hokkaido Cancer Center, Hokkaido, Japan. Nine volunteer reviewers, who were provided with the URL of the Panoptiq file, the original cytopathological diagnosis, and the clinical information, were asked to classify the cytopathological diagnosis of each case into 4 diagnostic categories (benign, atypical, suspicious, or malignant). We examined the consultation benefit (CB)-how much closer the reviewer's cytopathology diagnosis came to the final histopathological diagnosis than the original cytodiagnosis. The CB scoring system was decided in advance.

RESULTS

All 9 reviewers showed a positive total CB score and 2 reviewers showed a significantly higher CB score (Wilcoxon's signed rank test). The representative diagnosis (ie, the most frequently rendered diagnosis in each case) also showed a significant CB.

CONCLUSIONS

Our small-scale experimental study, in which Panoptiq was used in the diagnosis of cases that were difficult to diagnose definitively by breast FNA, revealed a positive CB score by every reviewer and the representative diagnosis showed a significant CB. The study suggests that Panoptiq could be used for cytopathology consultation.

Robotic Telecytology for Remote Cytologic Evaluation without an On-site Cytotechnologist or Cytopathologist: An Active Quality Assessment and Experience of Over 400 Cases

BACKGROUND

The first satellite center to offer interventional radiology procedures at Memorial Sloan Kettering Cancer Center opened in October 2014. Two of the procedures offered, fine needle aspirations and core biopsies, required a rapid on-site cytologic evaluation of smears and biopsy touch imprints for cellular content and adequacy. The volume and frequency of such evaluations did not justify hiring on-site cytotechnologists, and therefore, a dynamic robotic telecytology (TC) solution was created. In this article, we provide data on our experience with this active implementation. Sakura VisionTek was selected as our robotic TC solution.

METHODS

A retrospective analysis of all TC evaluations from this satellite site was performed. Information was collected on demographics, lesion location, imaging modality; a comparison of TC-assisted adequacy with final adequacy was also conducted.

RESULTS

An analysis of 439 cases was performed over a period of 23 months with perfect correlation in 92.7% (407/439) of the cases. An adequacy upgrade (inadequate specimen becomes adequate) in 6.6% (29/439) of the cases. An adequacy downgrade (adequate specimen becomes inadequate), is near zero at 0.7% (3/439) of the cases.

CONCLUSIONS

Dynamic robotic TC is effective for immediate evaluations performed without on-site cytotechnology staff. The overall intent of this article is to present data and concordance rates as outcome metrics. Thus far, such outcome metrics have exceeded our expectations. Our TC implementation shows high, perfect concordance. Adequacy upgrades are minor but more relevant and impressive is a near zero adequacy downgrade. Our full implementation has been so successful that plans are in place for configurations at future satellite sites.

Turning Microscopy in the Medical Curriculum Digital: Experiences from The Faculty of Health and Medical Sciences at University of Copenhagen

Familiarity with the structure and composition of normal tissue and an understanding of the changes that occur during disease is pivotal to the study of the human body. For decades, microscope slides have been central to teaching pathology in medical courses and related subjects at the University of Copenhagen. Students had to learn how to use a microscope and envisage three-dimensional processes that occur in the body from two-dimensional glass slides. Here, we describe how a PathXL virtual microscopy system for teaching pathology and histology at the Faculty has recently been implemented, from an administrative, an economic, and a teaching perspective. This fully automatic digital microscopy system has been received positively by both teachers and students, and a decision was made to convert all courses involving microscopy to the virtual microscopy format. As a result, conventional analog microscopy will be phased out from the fall of 2016.
