I'd be happy to start off with that.
I think there is evidence that fee-for-service works for getting more. Paying on a piecework, patchwork basis provides an incentive to work more, to see more patients. For those doctors who have an above-average case mix or acuity in their patients, certainly it's a disadvantage to them when they're paid on the average.
On the other hand, there is some evidence that salaried physicians certainly back off in terms of the amount that they're willing to work. They're less willing to work on call, they're more willing to go home at 5 p.m., things like that.
First, this is why my recommendations are around defining what we want to achieve first and then aligning the funding incentives behind it. I think that a mix that will probably work in Canada is a model that achieves a salary plus a partial fee-for-service payment that encourages people to work more, if that's what we want.
