As NatCh alluded to, you should make an attempt to document (if appropriate) in medical record that patient has failed previous conservative measures (and listed the failed conservative measures) before proceeding with ELECTIVE surgery. If your elective surgery does go wrong and leads to malpractice lawsuit or peer review by hospital or state board, at least there is an indication for the elective surgery by documenting that patient had already failed conservative treatment options. This is a good practice for anyone that you plan on taking to OR for elective surgery.
As for ABFAS case analysis, they are doing a new process starting with 2015 cycle. Since there are no more oral exams, ABFAS will be doing a "deeper" case analysis of all submitted cases for the credentialling portion of the Board Certification process. As with the past, you are require to submit all of the progress notes for the patient. Since ABFAS is a surgical board, they will most likely focus more on proper indication of the surgical procedure than whether or not patient has exhausted conservative treatments before proceeding with surgery. However, you never know with this new "deeper" case analysis.
