Why sub-scores and the CMS methodology matter
The overall score is a composite of three weighted sub-ratings published by the Centers for Medicare & Medicaid Services: health inspection results, staffing levels, and quality measures. Because CMS caps the overall score at the health-inspection tier and then adjusts up or down based on staffing and quality, the sub-scores often tell a sharper story than the headline star count alone, a 3-star facility with weak inspection history reads differently from one held back by thin staffing.
National research consistently shows that ownership structure, staffing hours, and turnover are the three operational levers that correlate most strongly with resident outcomes, ratings and fines are lagging indicators of those upstream choices. The staffing metric in particular is the one most strongly tied to resident outcomes in peer-reviewed literature.
For families evaluating this facility, the CMS record should be read alongside a site visit, direct conversation with current residents and their families, and review of the state health department's most recent inspection report, the star rating is a starting point, not a verdict. All data on this page is sourced from CMS Provider Data and the Nursing Home Compare program; always verify the same record on Medicare.gov Care Compare and with the facility or your state survey agency before making placement decisions.
