    For companies committed to standards, it is fair to say that two standards are too many! But that is what we face all the time … existing company standards and emerging industry standards. We know industry standards are the way to go, but we need the transition period to be short. We’ve been in transition for years, yet we seem hardly to have started.

    Over a number of years, CDISC has created a number of SDTM domains and terminology for these domains. And there is a 300 page implementation guide for around 30 of these domains. But there are several problems associated with this work:

    The rate of content creation is too slow, with development time measured in years rather than weeks or months. So, for example, GSK has more than 60 core standards, 400+ therapeutic standards, and 250 validated rating scale standards whereas CDISC covers maybe a fifth of this. Every time a new SDTM domain is created, we have to consider whether to change our standard. At the current rate of creation we’ll be doing this for many years.

    The mechanism for creating terminology is too slow: there are still under 100 CDISC codelists in EVS whereas GSK has approximately 4,000. And the mechanism for creation is too fragmented. For example, the lab test codelist was first released with under 100 codes, the second release had around 400 and the latest release has around 840. But the GSK codelist currently has 1380 and these are written into contracts with central labs. When should we switch from an existing GSK codelist to a new CDISC codelist?

    The SDTM domains are not underpinned by a sound information model. This results in the need for lengthy documentation, the lack of consistency between implementations of a given SDTM domain and the continuing burden of mapping operational objects to SDTM. CDISC recognise this and, in time, CDISC SHARE (based on a solid information model) will provide the underpinnings for SDTM.

    Continuing with the current approach to content creation will not deliver in the sort of timescales that are needed. Dave asks these questions:
    • Is it that CDISC now needs a new business model?
    • Is it time that we have to accept that CDISC needs more resources?
    • Do we have to give up on the idea of volunteer led standards development?

    To my mind, there are three key changes that need to be made:
    • Get paid project management/team facilitator resource and logistical support on board, so that team members can focus exclusively on the content rather than having to schedule and run meetings, find volunteers, “train” people, write documentation, respond to review comments etc.
    • Ask volunteers to simply focus on the content – those that are most valuable to CDISC tend to be those most valuable to the company they work for and their time is a scarce resource. We need to find a way to use their time more effectively. Short periods (e.g. one week) of activity would be much more effective than spreading this time commitment across several months.
    • Change the process for content creation. Focus should be on creating SHARE based content rather than SDTM based content (creation of SDTM domains from SHARE content should be largely automated). Here is a much leaner process:
    o Companies divide up the work of identifying research concepts of interest. Each area would probably require 3 or 4 people (2-3 clinical people plus one facilitator who understands the deliverable) the equivalent of a week’s effort to do this. Probably a lot of the work would be in documenting rough definitions of the research concepts.
    o Other companies review these packets and add to them. Similar groups of 3-4 individuals spend 1-3 days effort on this.
    o For each area, a cross-company group “polishes” the set of research concepts, agreeing definitions, identifying attributes of interest (from a checklist), identifying where terminology would be needed, and specifying terminology (if easy). Group should not be too big, perhaps half a dozen, including a facilitator. Administrative assistance (for documenting all this) would probably be needed. Amount of effort would depend on the number of research concepts defined. Perhaps 1-2 weeks (if it could all be done in one go), more if it’s chopped up.
    o Some kind of public review.
    o Incorporation of public review comments. Historically, this has been a very effort-intensive administrative task but there are ways in which this can be done in a more cost effective manner e.g. via use of a smart wiki based approach. And with simpler deliverables the number of comments should be less.
    o Separate development of terminology needed (variable resource needs)

    Of course, this would require some funding to be made available, but the sums required are not huge.

    What do others think?
