Touring a nursing home in Ontario
Ask the same questions of each facility so the answers are comparable. The ones that separate good homes from poor ones are rarely about décor.
- Who is the director of nursing, and how long have they been here? Administrator and nursing turnover is published for every facility and is the clearest early warning sign.
- What are the staffing numbers on the unit my relative would live on? Facility-wide averages hide a thinly staffed wing.
- What happened in the last inspection, and what changed afterwards? Ask to see the plan of correction, not just the citation.
- How does Medicaid work here? Whether a facility accepts Medicaid on admission, or only after a private-pay period, changes the total cost more than any published average.
- How often do residents leave for the hospital? Rehospitalization rates trace directly back to staffing and clinical capability.
