Traditional educational methods change clinical practice only with con
siderable effort and difficulty. In particular, the teaching of critic
al appraisal in the setting of journal clubs does not increase the amo
unt of medical research read by trainees. Experiential learning theory
, corroborated by the success of problem-based learning, encourages us
to link learning to the numerous medical questions that physicians ge
nerate while providing patient care. Systematic reviews can link these
questions with the results of research that would otherwise be diffic
ult to locate, read, and appraise. Systematic reviews are a uniquely p
owerful mechanism for teaching, and they offer teachers a new opportun
ity to model rational and effective use of information. Systematic rev
iews should be made available at clinical sites for use during ''teach
able moments.'' Resistance to the use of systematic reviews can be red
uced by using existing journal clubs to teach about the strengths and
limitations of these reviews. The point that systematic reviews are me
ant to assist, not replace, clinical decision making deserves emphasis
in such teaching.
