I suspect the dealing with heart type things with multi crew only restrictions is pretty common between both systems.
I also suspect the dealing with Single pilot aircraft is also similar as well.
We had an FO that had been off for months recovering from something completely different, and had just been knocked back again for 3 months. I suggested "have you suggested a multicrew only restriction 6 month medical?" err no, two days later they were flying again. Unrestricted 6 months later and the full year.
Quite rightly the single crew standards are different to the multicrew.
