What Do I Do If The Doctor I Work For Is Cognitively Declining And Should Not Be Practicing?

I work at a private practice for a physician who is nearly 80 years old. Lately it has become painfully obvious that he is not mentally fit to practice safely anymore. He cannot remember conversations from just minutes earlier, repeats labs during the same visit, forgets what has already been done, and sometimes tries to re-examine the same patient moments later. He becomes confused easily and sometimes seems delusional, like insisting a patient is still planning to travel internationally even after we have clearly discussed that she is not.

What makes this worse is that he becomes aggressive when corrected, and has yelled at me in front of patients. I always try to stay calm and professional, but it is incredibly stressful and humiliating. I also recently found out his wife may be completing his recertification tasks for him, which feels like fraud on top of everything else.

I do not know what to do. I am just support staff, not a physician, and I am scared to report this because I do not want to lose my job or get blacklisted. I care deeply about the patients, but I feel completely alone and overwhelmed. I have started documenting things, but is there anyone I can safely report this to without it coming back to me? Would a therapist or a third party be able to help?

I do not want to sit back and enable harm, but I am scared. Has anyone been through something like this?

So update: the reason I have not left this job although I have wanted to is because I am moving in 7 weeks. It's too late for me to get a new job because I am moving so soon and absolutely need this job for 1. Money and 2. admittance to further education. This doctor has won many awards (many MANY years ago) and is loved and respected by his patients despite them noticing his obvious cognitive decline. He unfortunately only works in his own practice ran by his wife so there is no way I can file a complaint that's not with the state medical board which requires me to identify myself. My issue is that he has a lot of pull with the universities I am currently applying to. Him and his wife have previously retaliated against employees who have asked him to get cognitive testing. I know that not reporting him is 10000x worse than reporting him, but due to his connections, him and his family have the ability to squash my chance of ever becoming a licensed provider. Absolutely lost about what to do, as of now he is not causing any danger to PT's as everything he does is meticulously reviewed by nurses and MA's, but still what he is doing is malpractice and somewhat fraud. I am one of the main people in the office who double checks all of his work and since I am leaving who knows who they will hire... they have a track record of hiring young college students to do my current job who have no clinical experience. My heart tells me reporting him is the right thing to do, but my brain tells me no as it will jeopardize my future. I'm curious if I should consult a lawyer or therapist or other doctor and if they could report this for me, as doctors and therapists are most often mandated reporters. As well if I went ahead and reported him to the state board what are some proactive measures I could take to protect myself from defamation towards my prospective universities. …
