How to read this report. Every nursing home receives some citations. One citation does not mean a facility is unsafe. Look at how serious the findings were, whether the same problems keep coming back, and whether things are getting better or worse. Learn how inspections work.

Medicare's star ratings compare nursing homes within the same state for health inspections. A 5-star facility performed better than most in its state; a 1-star facility performed worse than most.

Stars are calculated by CMS, not by us. We do not create our own safety score.

An inspection cycle is roughly one year and includes the standard inspection plus complaint investigations. Counts depend partly on how many complaint investigations occurred, so treat small changes with caution. Red bars include at least one serious citation.

Staffing and rating trends will appear as we collect monthly CMS releases. We have one month so far, so a staffing trend cannot yet be determined.

Repeat findings

These requirements were cited on more than one inspection date in the last three cycles.
