It's very true that the service is not just provided by doctors. In fact, I would argue it should not just be provided by doctors, because it is extremely expensive.
In order to innovate in the health care dollars and optimize the spending, you should have people do the most that they can with their training level. If personal support workers have palliative care training, they may be able to administer pain control drugs and work in that area. It's the same thing for nurses. Nurses, especially in remote areas, can rise to the occasion and be walked through how to administer palliative care from a palliative care specialist, and then physicians could take over. The gap today with palliative care specialists is so great that it will not be closed for some years.
