It's more than just the job description, I believe many EHR vendors require people who use particular modules to be "certified" for that module. Obviously this leads to a silo effect where the information is available but one clinician may need to request another clinician to actually read the data to them.
If you need the anesthesiologist on call to come back to the hospital just so the surgeon can see what drugs were given during the case and what the vital signs looked like, your EMR is less useful than paper.
