To make an informed selection between traditional Medicare and a Medicare m
anaged care plan, a consumer needs to understand the implications of choosi
ng one over the other. What are the implications of plan design for care, c
ost, and patient autonomy? Consumers need information about these questions
. However a barrier to developing this consumer information is the lack of
a consistent body of evidence. An intermediate step is to tap expert knowle
dge. The purpose of this study is to use expert consensus (across a spectru
m of health care experts) to identify the implications of plan design. Expe
rts were surveyed and the degree to which there is consensus provides an in
itial picture of what experts judge to be important to the consumer. The fi
ndings show that experts agree on several implications associated with choo
sing managed care over the traditional Medicare plan. They also agree that
many of these attributes vary considerably across health plans.
