Most arguments with a refusing father are about what is happening now. Is he fine? Is he eating? Was that a bad night or a new normal? You cannot answer those questions from memory, and neither can he, which is why the argument goes in circles. The fix is a baseline: a plain written record of how he was when things were working, so the present has something to be measured against.

Write the Good Stretch Down First
Pick the most ordinary stretch you can remember, a time when he was getting around, cooking or at least eating, answering the phone, and keeping his own schedule. Write it as a list of facts, not impressions. Walked to the mailbox without a hand on the wall. Drove to the store. Made his own coffee. Answered the door on the first knock. Keep to what you saw, and note who else saw it, because a second person's memory holds up better when the argument starts.
Then Log the Present Against It
Once the baseline exists, keep a short running log with one line per visit or call. Each line answers the same four questions: what he did on his own, what he needed help with, what he refused, and what you had to do. Keep it in one place, a notebook or a shared note that more than one person can open. The log does not have to be complete. It has to be consistent, so the difference between then and now shows up on paper instead of in your tone of voice.
What the Log Is Good For
A log is what you bring to the conversations that otherwise go nowhere. It lets you say 'you used to answer the door on the first knock, and last visit it took four' instead of 'you are not okay.' He can argue with a feeling. It is harder to argue with a list, especially one you show him and he is willing to read. The same record gives his doctor something specific to hear, and gives a lawyer a written trail that shows what changed and in what order, without you rebuilding it from memory under pressure.
Be careful about what the log proves. It shows change. It does not name a cause, and it does not decide whether he can manage his own affairs. Those questions belong to his doctor on the medical side and to a lawyer on the legal side. Bring the log to them. Do not wait for a decision before you start keeping it.
What to Check Before You Start
Ask who will need to see these notes: a sibling, a hired helper for non-medical errands, or the doctor's office. Then decide whether Dad knows the log exists. If he does not, keep it anyway, but keep it factual and private until you have a reason to share it. Gather the papers you already have, such as discharge instructions and visit notes, into the same folder so the log can point to them instead of repeating them.
The Next Move
Tonight, write three lines: one thing he used to do easily, one thing he does only with help now, and one thing from the last visit that you did not expect. Put them in a note on your phone, then make the first real log entry at the next visit or call. For a local starting point on the paperwork and the care questions, the Local Help in St. Louis page lists where to begin. Hold your log to the standard you would hold anything you hand a doctor or a lawyer: specific, consistent, and in your own words.
