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 hospital27.2%State average: 23.0%About average
- Needed an emergency room visit20.7%State average: 11.2%Worse than average
- Newly given antipsychotic drugs0.6%State average: 1.5%Better than average
Physical therapist time: about 4 minutes per resident a day. That is less than the state average of 6 minutes. If rehab is the goal, ask how many therapy sessions a week to expect.
Long-term care

- Falls with a major injury1.4%State average: 1.6%About average
- Pressure sores (bedsores)7.5%State average: 4.3%Worse than average

Who pays, and how full it is

Beds in use, on average72%California typical: 90%
Cost of care per resident day$502California typical: $464
Shares of resident days, from the home’s Medicare cost report for the year ending December 2024. The cost per day is what care costs the home to provide, not the price you would pay; ask the home for its private-pay rate. A busy home may have fewer open beds, so ask about availability.
