I just started writing an end user manual for the University of Colorado. My target audience are researchers/investigators that will be using the CDM. I started last week, so I have a general outline and a bunch of notes. I am basing my document on the OMOP conventions. And I plan to add information on how the source EHR differs from the CDM, what data are not in the CDM, what data are in the CDM, information regarding conventions that are specific for our instance of the CDM, Atlas for cohort building, and Athena for ease of navigation through the vocabularies.
Since I just started this process, I would appreciate any guidance from anyone else that is attempting, has attempted, or has completed this task. I’m particularly interested in academic institutions that have “customized” the CDM for researchers with a healthcare provider or healthcare research background, but welcome all feedback!
