As the quality of neurological care becomes a mutual objective of phys
icians, patients, and health planners, increased demands on cost savin
gs will create conflicts that could threaten the ethical basis of medi
cal practice. Physicians will see increasing ethical conflicts between
their fiduciary duties to make treatment decisions in the best intere
st of their patients and their justice-based duties to conserve societ
al resources. These conflicts can be best mitigated if physicians main
tain their orientation as patient advocates but practice cost-consciou
s clinical behaviors that consider the cost-effectiveness of tests and
treatments and do not squander society's finite resources by ordering
medical tests and treatments of zero or marginal utility. Health syst
em planners should resolve their conflicting objectives of quality and
cost control by rigorously defining and measuring quality through phy
sician leadership and by implementing cost-control measures that enhan
ce the quality of medical care. Managed care organizations voluntarily
should forsake financially successful but blatantly unethical cost-sa
ving schemes, such as gag clauses and end-of-year kickback payments to
physicians, because these schemes diminish patients' trust in physici
ans and degrade the integrity of the patient-physician relationship. S
tate and federal laws should prudently regulate these unethical cost-s
aving schemes to the same extent as they have for the harmful conflict
s in fee-for-service medicine.
