CMS Star Ratings

Overall rating

CMS’s composite of the three ratings below. Missouri average: 2.5 stars.
Health inspection
★★☆☆☆
Based on the last three years of on-site inspections and complaint investigations — the rating CMS weights most heavily.
Staffing
★★★★★
Nurse and aide hours per resident per day, adjusted for how much care residents need, plus staff turnover.
Quality measures
★★☆☆☆
Clinical outcomes CMS tracks, such as falls with injury, pressure ulcers and hospital readmissions.
Abbey Senior Health holds a 3-star overall rating, CMS’s middle tier. Its health-inspection rating is lower than its overall rating — the overall score is being lifted by staffing or quality-measure ratings, which draw partly on facility-reported data. None of this tells you whether a bed is open, whether your insurance is in network, or whether the facility will accept a given level of care — confirm those three directly with the facility before you commit.
