Impact of cross-enterprise data sharing on portable media with decentralised upload of DICOM data into PACS

Abstract

Objectives

To evaluate portable media utilisation for image data sharing between enterprises. To predict the costs required to keep up with the trend. To identify related problems.

Methods

A software package was developed to include patient image data from CD into our normal workflow. The trend in the workload of CDs that were uploaded into a Picture Archiving and Communication System (PACS) over 89 months was analysed. The average number of images per month (and per investigation) was calculated to provide the estimation of storage and cost required in the whole process.

Results

All Digital Imaging and Communications in Medicine (DICOM) files can be read from compact disc (CD) on any workstation in the hospital, processed quickly to the central server and checked after storage using the software tool. A total of 33,982,404 images from 88,952 CDs have been stored into the PACS system. In recent years, the stored images have reached an average of 4.2 terabytes (TB) uncompressed annually.

Conclusion

Integrated information about patients is clearly needed to provide easy and timely access to these data. The steadily growing storage can be solved by a more automated approach to portable media handling or the installation and acceptance of network-based transfer using cross-enterprise document sharing (XDS).

RSNA 2013 - ICIA24 - using IHE profiles to plan for medical imaging

Top five forces to medical imaging are defined to be:

1. Cost reduction

2. Daunting PACS migration

3. Silos of imaging sources

4. Complexity of effective image sharing

5. Leverage health IT best practices

The road to effective image sharing by implementing Vendor Neutral Archive (VNA) taking care of access consolidation. Access consolidation requirements are:

1. Integrated clinical systems

2. Portability

3. Scalable

4. Extensible

5. Content accessible

IHE profiles are there to break the vendor neutral consolidation barriers.

IHE XDS provides the profiles to allow content (vendor) neutral archive. Several profiles are defined to describe the required capabilities within an XDS affinity domain such as PIX (patient identity cross referencing) , BPPC (basic patient privacy and concent) and XUA (cross enterprise user authentication).

The XDS environment can be setup as a federated, centralized or hybrid environment.

Cross enterprise data sharing

In radiology the data sharing between healthcare enterprises is a growing challenge and concern. Large amounts of CDs and DVDs are being shipped daily with big problems concerning the handling, viewing, upload, etc. Health Imaging has published a short article about 5 tips for optimizing image sharing. It is worth to read for those involved.

Is the end of the CD era approaching?

The distribution of patient imaging data on CDs and DVDs is commonplace in almost every hospital in developed countries. However, with the increasing demand on imaging and the increase in the amount of data generated at each acquisition, the number of CDs and DVDs is increasing dramatically and the flood of portable media is almost impossible to handle. Network based sharing over the internet using secure protocols and profiles such as XDS(i) could solve the problem.
