Ten thousand times yes. My family has a similar policy: everybody who goes to a hospital-- whether outpatient or inpatient-- has a minder or a tag-team of minders, to prevent horrible accidents or on-purposes from happening-- it's also helpful for protection against the inevitable future billing fraud. We've had too many bad experiences to leave it to chance. Double-check medications and dosages, and keep time/date notes with all the details you can manage: what kind of room were they in, how many meals did the hospital provide, what drugs were given and when, which doctors came in, when, and what did they do? What was the room number? My mother once spent months fighting billing fraud about a private room, when she'd been sharing with two other people-- she won because she forced the hospital to divulge the number of the "private room" they were charging her $$$ for... and was able to prove that this was actually a hospital office, not a patient room at all.

One family member in particular has to have a power-of-attorney-equipped bodyguard every time he's in a hospital (and that's been frequent!), because somewhere in the bowels of his medical records, it notes that he was once on seizure meds. It does not note that the side-effects of those meds were so awful he'd rather die than go back on them, because the doc who helped him wean off them would not (could not) go on record for that, it was so risky, and also doesn't note that he has recovered from the injury that caused the seizures, and no longer needs them. So every. dang. time. he ends up in a hospital, some fracking neurologist gets called in because of that decades-old record, and they try to put him back on the meds. The family has nearly come to blows with hospital staff over it, and on at least one occasion has had to call in a pastor and a lawyer as reinforcements. Totally, completely bonkers. These are not people who believe in informed consent or patient agency.

And that's before you even get to actually *innocent* mistakes...

Nearly lost a very young relative after a totally routine tonsillectomy, because they prescribed an adult dose of opiate painkiller to a six-year-old. Same would have happened to another child in the family if the parent hadn't opened the bottle at the pharmacy, looked at the pills, and been like: are you sure these are right? I don't think the kid can swallow anything that big... Always check, double-check, triple-check. This is the internet age-- you can look up the medication and verify that the pills are the right color, shape, size, and dosage for the patient's weight.

And don't go to hospitals alone if you can help it. If you don't have a team, now's a good time to set one up!
