<p><pre><code>   I&#x27;m guessing that a similar situation exists with
   doctors; physicals, vaccines, and a handful of common
   diseases (like colds) probably make up a sizable
   percentage of visits. There&#x27;s a market for someone who
   can just handle these cases and pass them off to the
   higher grade doctor when the need arises.

Those are called GPs up in Canada. They do more than just deal with colds, but the system is set up so you first go through a GP and then are referred up.
