Ask what discharge actually includes.
Before she leaves, ask who is coming to the house, how often, and for how many weeks. Home health after a hospital stay is usually a few short visits from a nurse or therapist. It is not someone to help her wash, dress or eat.
Get the instructions in writing.
Ask for the medication list, the follow-up appointments and the warning signs on one page, and ask the nurse to read it through with you. Ask what to do at 2am and who to call, so the answer is decided before you need it.
Plan the first three days, not the first month.
Who is in the house tonight. Who takes her to the follow-up. Who fills the prescriptions before the pharmacy closes. Most readmissions begin as a small gap in those first days.
Make the house fit her for a while.
Clear the path to the bathroom. Move what she needs to waist height. Put a light where she gets up at night. Rearranging a few things beats asking her to be careful.
Watch for the second week.
Help often arrives for discharge and fades a week later, exactly when she gets tired of being careful. Decide now who checks in then, and what happens if she is not recovering the way you hoped.
