In addition, if there is a desire
to compare doctors or to provide them with feedback about
their relative performance, then all portfolios must contain the
same data collected in a similar manner. Otherwise, there is no
basis for legitimate comparison or benchmarking. Portfolios may
be best suited for formative assessment (e.g. feedback) to drive
practice-based improvements. Finally, to be effective, portfolios
require active and ongoing reflection on the part of the doctor.
