Health care systems are widely criticized for limiting doctors' roles as pa
tient-advocates. Yet unrestricted advocacy can be unfairly partial, costly,
and prejudicial. This essay considers three solutions to the problem of ho
w to reconcile the demands of a just health care system for all patients, w
ith the value of advocacy for some. Two views are considered and rejected,
one supporting unlimited advocacy and another defending strict impartiality
. A third view suggested by Hume's moral theory seeks to square the moral d
emands of professional advocacy and just health care systems. A moral basis
for limited advocacy exists when it can be justified from a general or mor
al vantage. Consequently, ethical aspects of professionalism are not necess
arily on a collision course with health care systems incorporating managed
care. This solution is compatible with goals regarding the importance of hu
manistic education and professionalism to build patients' trust.
