Hi Mohamed,
In Cumberland, Md:
Active medical staff admits, takes ER call, has to attend department meetings, serve on hospital committees, etc.
Affiliate (Courtesy) do not admit, do not take ER call, do not have meeting or committee responsibilities.
Most departments exempt physicians from ER call at age 55.
I am on telephone call for our patients close to 24/7. Typically only a few calls a week. And telephone call is much easier when you know all of the patients.
