Thank you Joseph and David for the replies. I have a

How can I test this?

This is an interesting point, because in my data I
have 50 clusters and 410 observations, so the number
of patients referred by a physician ranged from 1 to
43 with a median of 5 referrals.
I guess the question that remains is whether or not I
can justifiably use this approach?
Thank you again,
Ricardo.
