What to ask when you call or visit
A general checklist for any nursing home, not advice about this one. Medicare also publishes guides on medicare.gov.
- Is the home certified by Medicare and/or Medicaid, and does it have a bed for the care you need (short-term rehab or long-term care)?
- Can you see the latest state inspection report? Ask how any problems found were fixed.
- How many nurses and aides work on each shift, at night and on weekends? Is there a registered nurse on site at all times?
- Which doctors see residents, and how often? What happens in a medical emergency, and which hospital is used?
- What therapy (physical, occupational, speech) is offered, and how many days a week?
- Are residents clean, dressed and taking part in activities? Do staff speak to them kindly and answer call lights quickly?
- What do the daily rate and extra services cost, and what do Medicare, Medicaid or your insurance pay? Ask for it in writing.
- Is there a resident council and a family council? How are complaints handled? Ask for the long-term care ombudsman’s contact.
- Are meals appetizing, and can the home meet special diets, language needs and religious or cultural preferences?
- Visit more than once, including at a mealtime or in the evening, without an appointment.
