The only way to bill the abusers would be to enable the doctors to classify a visit as non-legitimate and most probably never would for fear of discouraging patients, so its a non-starter, IMO.
I honestly don't see how "putting doctors on salary" does anything: it flattens their wage earning potential (in cases where they don't own a part of the clinic they work out of) and encourages them to say "OK I've done my shift, I'm done and to hell with the X number of people in the waiting room". With doctors who own a part of their practice, its about the number of patients they can get through and bill the provincial plan for: if you "nationalize" (for lack of a better term) their clinics, you take away most of the incentive for them to stay in Canada vs practicing in other countries, unless that salary is huge.
In Ontario more and more doctors are going on salary, Wulfie. Well, not exactly salary, but on capitation, where they get so much per patient per year. This regardless of how many times the patient visits the doctor.
As to "OK I've done my shift, I'm done and to hell with the X number of people in the waiting room", that is easily taken care of. If the doctor is not available and his patient has to visit another doctor, the fee for the other doctor comes out of the first doctor’s payment.
The doctor is obliged to provide after hour service to the patients (that also cuts down on costs). Most doctors work as a group, so it is OK for one doctor to see another doctor’s patient from the same group, nobody gets penalized for that. But let the patient go outside the group and the doctor does get penalized for it. So doctor cannot just abandon his patients, now that he has got the payment. If the patient goes to another doctor as a result and that doctor charges OHIP 100 $, that comes out of first doctor’s income.
So that problem doesn’t really arise. But there is a big advantage to salary. Since doctor’s payment does not depend upon individual visits, the doctor usually gives patient prescriptions for one year (without salary, he may give prescription for any period between one month and one year). That leaves him with more time to look after really sick patients, preventive care etc. He gets extra bonus for preventive care, so there is incentive for him to do preventive care.
Salary is a win win situation, doctor does not lose out, the salary is set at sufficiently high level for that not to happen. Ontario is encouraging doctors to go on salary, offering incentives etc. and more and more doctors are going on salary. My wife is considering it, her group may switch over to salary in the next few months.
