Quite the opposite; it helped weaken it. Look it up for yourself: http://de.wikipedia.org/wiki/Praxisgeb%C3%BChr#Folgen_der_Praxisgeb.C3.BChr. The stated goal was reduced visits to a doctor. It failed to archieve even that after a bit more than three years. Since then, the number of visits per inhabitant of Germany was even higher than before the introduction. Even worse, it turned out that it was effectively a tax on the poor, as poor people tended to go visit the doctor even less, especially for preventive cancer examinations by dermatologists and gynecologists (numbers are in the source). The effect will be rising cancer treatments in the future, which will be way more expensive than the savings from the examinations.

Practically every one of the reforms was economically short sighted and will do more harm than good in the long run - exactly as Germany's treatment of Greece  right now.
