The CDM Working Group wants you to know about CDM v5.5!
Calling all workgroups! CDM v5.5 is slated to be released at the end of August. We in the CDM working group would like to give you a heads up as to what you can expect from this upcoming version so you can being to prepare. As this is a minor version, all changes are backwards compatible with CDM v5.4, but we do have some exciting additions. You will see some new vocabulary support tables meant to make community contributions easier and some new columns in patient-level event tables to make our data model even more robust! Please see the summary table and document below for details and feel free to contact us on the CDM Working Group channel on teams or reply here on the forums with any questions.
