I think you've hit the nail right on the head.
In health, change is very difficult. We're completely risk averse, and if that's the way we've been doing it for 20 years, it must be good. I think the only way to achieve effective change is that this health human resources plan for the next 10 to 20 years has to be based on a different service delivery model. We cannot continue to provide the same service delivery and add more of the same to the status quo.
So change is essential. It should be collaborative, with a full scope of practice and health care professionals working in a team. The biggest factor to effect that is to be able to measure quality outcomes and base those decisions on evidence, which we don't have today.
