At least in sweden we got lots of health clinics and cant find it in the Amenity section. This is something that need to be there.
and one more thing that isn’t that inportant but still i cant see m to find a poi for Gym, that would be great to add gyms to the maps aswell.
There might not be any presets for health clinics, but something on the Wiki page will cover it: http://wiki.openstreetmap.org/wiki/Proposed_features/Healthcare_2.0 and http://wiki.openstreetmap.org/wiki/Healthcare_2.0/Examples .
For gymn, there is not a lot of common tagging, but you can try amenity=fitness_centre or leisure=sports_centre (although that may not fit)
