Short-term rehab or long-term care?
Medicare rates these separately, and many homes are better at one than the other.
Short-term rehab
For a stay of a few weeks after a hospital visit, such as after surgery or a stroke.
- Sent back to the hospital16.5%State average: 25.7%Better than average
- Needed an emergency room visit8.4%State average: 11.9%Better than average
Physical therapist time: about 0 minutes per resident a day. That is less than the state average of 5 minutes. If rehab is the goal, ask how many therapy sessions a week to expect.
