More than 60 percent of hospitals have ethics committees. The wide-sca
le, voluntary adoption of these committees by hospitals is surprising,
given the lack of data on their effectiveness. Little effort has been
made to evaluate such committees, in part because of the lack of cons
ensus on their purpose. The argument presented here is that, from a po
licy perspective, the committees' purpose must bb to safeguard patient
s' interests; a framework for evaluating committees based on that obje
ctive is outlined. The criteria for evaluation include access, quality
, and cost effectiveness. Existing data are used to assess ethics comm
ittees, using these criteria. Based on available data, it is questiona
ble whether ethics committees are performing any better or worse than
alternative mechanisms to achieve the same goal.
