Good doctors use
both individual
clinical expertise and
the best available
external evidence
and neither alone is
enough. Without
clinical expertise,
practice risks
become tyrannized
by external
evidence, for even
excellent external
evidence can be
inapplicable to or
inappropriate for an
individual patient.
Without current best
external evidence,
practice risks
become rapidly out
of date, to the
detriment of patients.
