This is an ACCME adaptation of an Agency for Healthcare Research and Quality (AHRQ) definition of a gap in the quality of patient care where the gap is "the difference between health care processes or outcomes observed in practice, and those potentially achievable on the basis of current professional knowledge."
The ACCME does not want to limit the scope of CME providers' or learners' educational projects. Part or all of some professionals' practices include important non-clinical, non-patient care elements which are still considered relevant to continuing medical education.
When there is a gap between what the professional is doing or accomplishing compared to what is "achievable on the basis of current professional knowledge," there is a professional practice gap.
