Healthnet is a highly secured network to connect public health institutions. This guarantees the confidentiality and data protection of the digital information.

Telepathology network using the Healthnet VPN infrastructure.

Bandwidth of 1 Gbit/s.

Every hospital we are uses the same IT systems in order to reduce maintenance costs.

The macroscopist uses a Touchscreen computer connected to a camera on top of the macroscopy workstation. He has access to our LIMS (laboratory information management system) (DaVinci) and other services hosted by the LNS.

The digital microscope uses a direct Teamviewer connection. This allows the pathologist to remotely see and manipulate the virtual microscope from his office at LNS.

Use of virtual slide system for quick frozen intra-operative

telepathology diagnosis in Kyoto, Japan Diagnostic Pathology 2008 3 (Suppl 1) :S6

Comparison of delays prior to the use of Telepathology

showed a clear reduced time in frozen section reporting

(average of 15 and 20 minutes from CHEM and CHL

respectively).

Discrepancies between virtual and traditional frozen

section were analyzed, with no significant disadvantages

of a telepathology assessment Vs a traditional one.

-8 cases (out of 135) (5,9%) showed discrepancies

between frozen section and final diagnosis

-5 (3,7%) cases were due to sampling errors

-3 (2,2%) cases were interpretation errors

-1 (0,7%) case deferred

-Comparable to reported discrepancies in the

literature

-The use of DP (outside the scope of Telepathology for intraoperative frozen sections) in every-day routine reporting is still very reduced (under 5%)

-Philips High-throughput Ultra Fast Scanner

-Implementation technical challenges: consistent slide identification recognition, interoperability with different bar codes and lab equipment, image storage, remote access

-Implementation “cultural” challenges: reluctance to use of DP by part of the personnel, changes in workflow.

-Upcoming incentives (adoption of IA algorithms assisting diagnostic act, prioritize use of current standardized quantitative digital tools) might increase use of DP in the routine sign out setting.

Conclusions

-A project to integrate all the hospitals in Luxembourg with a central

Pathology Laboratory is underway.

-Two of the hospitals have been already integrated and as of May 2018,

the test phase in a third one (Centre Hospitalier du Nord-CHdN) has been

completed.

-The implementation of DP in the routine requires further investment,

both economically and behavioral. New functionalities and AI based

algorithms may tip the balance towards extended use of DP.

Telepathology’s impact on patient care and surgeon satisfaction has

proved beneficial due to:

1) Dramatic reduced time in frozen section reporting

2) Improved communication regarding macroscopic assessment, allowing

the surgeon to indicate the areas of interest (live mode)

3) Optimal frozen sections due to immediate freezing and samples not

subject to drying effect in long transportations

4) Collection of fresh and frozen tissue for biobank and research projects
