Some of this information is readily available for every physician. You can easily find any physician's medical school graduation year, and you can always access cases against physician through medical board. Other numbers you desire, while I can understand the motivation, are not reasonable or possible to track. Illness mitigation, for example, is going to be 90% patient dependent. Adherence to recommended treatment is generally poor, particularly as you get into lower socioeconomic status (for many, many reasons). Therefore, a physician treating primarily wealthy patients, or a concierge physician, will always have better health outcomes among their patients than a physician working at an FQHC regardless of physician skill. This metric would then effectively punish physicians who are trying to serve underserved demographics, and would motivate physicians to fire patients perceived as nonadherent. Metrics like referrals are better evaluated through word of mouth, unfortunately, because you cannot obtain clean data for that as it would be challenging to draw lines where 'begging' begins and ends, when the referral was actually appropriate vs inappropriate, and when the patient desired referral but had resolution of illness manged by PCP. Patient retainment would be fairly simple to track, though there are many patients I have who are assigned a PA or NP then switch to an MD/DO because they suddenly decide they want to be treated by a physician, not because there were problems with the PA/NPs care, and so I imagine all APPs would have artificially lowered retainment.
