I will have to look up actual numbers, but with 30 patients a day this is 25€x30x5x4=15000 a month pre everything. You take out taxes, costs, everything they need to pay in full and I guess the salary will not be very different from IT.
EDIT: I just looked up some numbers and you are right, MDs get about 5000€ net pour month in average, which is higher than IT
