Can rationing of health care by chronological age be justified on ethi
cal grounds? The principles of equality, solidarity, liberty and effic
iency are used as value premises in the discussion. Health care ration
ing by age is inconsistent with the principles of equality and liberty
. But in some situations such rationing has support from the principle
s of solidarity and efficiency. The compromise suggested is that, as a
rule, rationing by age should not be permitted, except in situations
with intrinsic scarcity (as is the case with transplantation) and in s
ituations with temporary extrinsic scarcity (as was the case with dial
ysis for a period of time). However, the main purpose is not to defend
this position, but to identify and analyze the ethical conflicts such
rationing gives rise to.
