This document discusses the ethical issues involved in healthcare resource allocation and priority setting. It examines principles of distributive justice and fair process. Priority setting involves considering clinical effectiveness, cost, need and ability to benefit. Fair allocation of resources balances equality of outcome, based on treatments being equally effective or cost-effective, with equality of persons where individuals are treated equally. A fair process of accountability for reasonableness is proposed to balance these considerations and allow for appeal of decisions. Exceptions to policies and a modified "rule of rescue" are discussed to account for identifiable individuals.
