Agenda

1. Review specific use cases to define the exact scope of the project (what is in and what is out of our bucket) and:
   1. articulate questions that require policy level discussion, review and decision (to be addressed in subsequent subgroup meetings of site leaders).
   2. specify technical requirements for what is "in the bucket" to be addressed in subsequent implementation planning meetings

Uses cases

Randy presented a couple of slides with different use cases. The goal of the meeting was to discuss the first ones and learn what are the mechanisms in place at each institutions.

Use case 1

The PI wants to use his own clinical images, with the clinical tools. He is not leaving his institution.

• At CHB and BWH, a PI can not have direct access to his data in PACS, he would need an IRB for research purpose. Some institutions have an easier IRB process in place for this type of case. We need to educate ourselves about the process at BIDMC and MGH.
• Tools that are in place for the PI to search his data.
  • At MGH you can use a physician's name to do a query in RPDR (The RPDR -Research Patient Data Registery- is a warehouse of clinical data from Massachusetts General Hospital (MGH), Brigham and Women's Hospital (BWH), Faulkner Hosptial (FH), Spaulding Rehabilitation Hosital (SRH), and Newton Wellesley Hospital (NWH) available for research purpose).
  • CHB and BIDMC are getting searching capabilities but they need to add radiology data.
  • At CHB, the search for radiology data is not automated, the PI must do it manually.
  • At CHB, surgeon have access to the PACS system and it is not reviewed by the Radiology Department. They search patient from their medical record number.
• Red flag rose by Rick Robertson from CHB:
  • The Radiology department already has problems with groups who access medical imaging data without asking the radiologists. It leads to different groups working on the same subject without collaborating with each others. He feels that by making the retrieval of clinical data easier, we will make it even worst.

Use case 2

Same as case 1 but the PI wants to use a research tool for post-processing. He needs to download the data.

• At CHB they can not do it without a review from Radiology. The request goes to the Informatics group. From the workstations, they can extract data from the PACS (as TIF for example).
• At BWH the PI needs to request a CD to be burned, he must have an IRB approved and Radiology has to give its approval. When the whole project is approved, the PI then gets DICOM access. He can use any approved DICOM viewer.
• In general, Osirix can connect directly to the PACS, it just needs to be configured the right way.
• Problem with heavy download: what happens if a PI decides to download 6,000 images?
  • At CHB some PI's tried before and of course it crashed the system.
  • At BWH the workflow is controlled.
