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 hospital12.0%State average: 21.0%Better than average
- Needed an emergency room visit1.1%State average: 9.8%Better than average
- Newly given antipsychotic drugs3.4%State average: 1.1%Worse than average
Physical therapist time: about 1 minute 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
For residents who live at the home for months or years.
- Falls with a major injury4.0%State average: 2.4%Worse than average
- Pressure sores (bedsores)6.8%State average: 5.9%About average
- Given antipsychotic drugs17.1%State average: 13.8%Worse than average
- Hospital stays per 1,000 resident days0.3State average: 1.3Better than average

Who pays, and how full it is

- 68% Medicaid
- 19% Medicare
- 13% Private pay, insurance and other
Beds in use, on average60%Maryland typical: 88%
Cost of care per resident day$413Maryland typical: $408
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.
