I'll give one example, of which there are many, and I would be very interested if Dr. Gratzer had a comment on it.
One thing we find constantly wherever we go is that mental health and addictions are a real problem, not in just the incidence and prevalence, but also, people who really need to see a psychiatrist often have unconscionable delays and with serious consequences. On the other hand, in terms of the number of people a psychiatrist perhaps needs to see, he or she doesn't have to see everybody who comes through the door just because of a referral.
In the model we took, we looked at the data on that and started to advocate this, I believe in Manitoba, to enhance the use of clinical psychologists not only in positioning in primary care offices, where a patient coming in who needs that sort of assessment can get it the same day, can just go to the next office. Similarly, clinical psychologists can be a filter for those patients who are referred to psychiatrists, and if the patient needs to be seen tomorrow, the patient gets seen tomorrow. If there can be a delay, you can delay it or you can go back to your family physician.
Whatever discipline in medicine you want to look at, the data that underpin those sorts of decisions can be extracted and they can be used.
