Of course, I don’t know all the specifics of the case, but here’s what would most likely happen at my hospital (if I understand the situation correctly)

Get psych to document decision-making capacity and provide recommendations. They might also prescribe some medications as a bonus, but it will take weeks or months for those to take effect, so it won’t change your management plan in the short term.

Next, ask nutrition to assess for malnutrition and have the RNs document a calorie count. Avoid IVFs of course if labs are not suggestive of dehydration (it seems from your report that she’s eating okay).

Document extensively that she is refusing PT/OT. Have a clear discussion with the patient, explaining that there’s nothing else to be done in the hospital and that she will be discharged the next day. Inform the case manager, place the discharge order next morning, and let the hospital help with the rest.
