Cookson, R. and Dolan, P. (2000). Principles of Justice in Health Care Rationing. Journal of Medical Ethics. 26(5): 323-329.
The authors compare and contrast need principles, maximizing principles and egalitarian principles with regards to rationing scarce medical resources. Overall, the authors believe that the general public supports a combination of the three principles (based on a study conducted with a relatively small sample where participants reacted to a scenario where they were given a fictional amount of money to use to treat one of four patients with completely different health challenges and demographics).
