Some developing countries like Canada and the UK have more standardized rationing mechanisms. It is said that in the UK, patients face long wait times and rationing of care in part because the National Health Service can't attract nearly enough medical professionals to meet demand. What are some other examples of rationing seen in other countries? In your opinion, is it ethical to use economic evaluations such as cost-benefit analysis, cost-effectiveness analysis, etc to control health care cost by rationing?
