This paper compares and contrasts three different substantive (as opposed t
o procedural) principles of justice for making health care priority-setting
or "rationing" decisions: need principles, maximising principles and egali
tarian principles. The principles are compared by tracing out their implica
tions for a hypothetical rationing decision involving four identified patie
nts. This decision has been the subject of an empirical study of public opi
nion based on small-group discussions, which found that the public seem to
support a pluralistic combination of all three hinds of rationing principle
. In conclusion, it is suggested that there is room for further work by phi
losophers and others on the development of a coherent al Ed pluralistic the
ory of health care rationing which accords with public opinions.
