The definition is at the beginning of the clue.
How the clue works
The definition is Average, meaning mediocre or nothing special. The wordplay starts with MEDIC (a doctor), which "takes" — i.e. contains — O (nothing, representing zero), giving MEDIOCE. Then RE (meaning "on" as in "on the subject of") is added at the end, producing MEDIOCRE.
