My father is in a caregiver facility. They gave him medications I specifically told them not to give. He fell 2 times in a 24 hour period. I asked to see what medications were given, the amounts & times/dates. The facility refused saying it is an internal document.
If your PoA is already legally active, is he in AL? Or MC? Or LTC?
I agree with contacting the ombudsman if the facility doesn't cooperate. Don't go in there with guns blazing or they will clam up further. Please know that elders fall very often for reasons that have nothing to do with medications. My own very elderly Aunt with dementia could walk with support. She fell 3x in her own home in the presence of a family caregiver, breaking a bone each time. Since elders who are a fall risk cannot be restrained even for their own good, they can go on to fall again and again until they disable themselves completely.
I wish you success in advocating for your Dad.
If you are currently acting as a POA for an incompetent senior, yes you have a right to view the medical records. Just as the patient would have a right to. If you are registered with this facility as the POA discuss your documents with them again, make the demand again, and then ask to speak with the doctors writing the prescriptions for medications. You may need to bring in an elder law attorney. It is illegal action to ignore a POA document that is legal and in force. Tell them you will be bringing in an attorney if the do not allow access to medical medication record at once. Then do so. Your elder's funds pay for you to get expert advice consults.
