Dr. Tony O'Connell:

We have already articulated a number of those. The consultant might have a sense of reassurance that the patient is safer being looked after by nurses. Occasionally, a patient wants a night away from home and does not want to leave if there is a risk that his or her pain might not be as well managed outside the hospital setting. There is also a potential financial incentive for the hospital from an inpatient stay. There are a number of incentives, and we are dealing with a balance between the two sides. That is why it is such a complicated change of practice.
