I too work with doctors and nurses. I have had great luck with food items. I purchase a coffee cup, single serving package of coffee and individually wrapped biscotti. Then I make a chocolate dipping spoon. Stuff the items in the cup and wrap in cellophane and decorate with a bow/ribbon and/or ornament.
For the spoon: Melt really nice dark chocolate (Valrhona or Calabaut) in a double boiler, just until chocolate pieces become shiny. Remove top bowl from simmering water and stir until chocolate is smooth. Let cool until just about hardened. Dip a color coordinated plastic spoon in the chocolate and fill the bowl of the spoon. Place on wax paper to cool. I sometimes place small Christmas sugar candies (see the cake decorating aisle) in the chocolate as they cool. Wrap the end of the spoon in cellophane or saran wrap and finish with a bow.
The whole idea may cost you $3/mug.
If you are really crafty, consider hand painting your own ornaments. You can pick up clear or frosted glass ornament balls from the craft store (like Michael's or Hobby Lobby). You can paint the outside or if you are really creative you can paint the inside with tiny brushes. I did a tie-dyed looking Christmas tree one year and made the ornaments. I dropped a couple of drops of paint inside and swirled. Then I repeated the process with other colors. They came out really nice. They might cost you $1/ornament to do.
Good luck!!
