professional development of internists. However, the available medical literature does not provide strong
support for the assumption that internistswith certification or recertification havebetter patient outcomes.
This relationship between recertification and patient outcomes needs more study. In addition, the
participation in the Maintenance of Certification program by internists with lifetime certifications has
beenlow,andrecertificationbyleadersininternalmedicinehasalsobeenrelativelylow.Somephysiciansin

needs to review its currentMaintenance of Certification program and make changes to enhance its clinical
relevance and educational value. We suggest that professional development should be based on focused
reviews of the current literature, which is immediately relevant to clinical practice, and that recertification
couldbebasedon completionof modules andmorefrequent, less oneroustesting.
