The Five-Star Quality Rating System has three components — Health Inspections, Staffing, and Quality Measures — each scored separately with its own calculation methodology. Most SNF administrators know their composite Five-Star rating. Few know exactly which of the 18 long-stay and short-stay quality measures are pulling their Quality Measures star below what they could achieve, or how much improvement in each QM is needed to move from 3 to 4 stars on that component.
MDS (Minimum Data Set) assessments are the data foundation for LTC quality reporting. Section GG functional scores drive ADL decline quality measures. BIMS (Brief Interview for Mental Status) cognitive scores affect antipsychotic use and dementia care measures. CAA (Care Area Assessment) trigger rates identify clinical risk areas. But MDS data lives in the MDS software system — PointClickCare, MatrixCare, American HealthTech — and getting that data into a cross-functional analytics view requires technical integration work most SNFs can't afford.
PDPM (Patient-Driven Payment Model) replaced RUG-IV in 2019 and fundamentally changed SNF reimbursement. Under PDPM, payment is based on case mix group (CMG) classification driven by clinical characteristics — primary diagnosis, function score, and comorbidity adjustments — rather than therapy minutes delivered. SNFs that don't analyze their HIPPS code distribution under PDPM may be systematically under-coding for high-acuity patients.
Five-Star QM Score Decomposition
The 18 CMS quality measures (long-stay: pressure ulcers, falls with injury, antipsychotic use, pain management, ADL decline; short-stay: rehospitalization, improvement in function, community discharge) each contribute to the QM star. Vizier shows which measures are in the lowest national percentile and quantifies the census impact of each star change.
Staffing Star Weekend Component
CMS added weekend staffing as a separate Five-Star component in 2023. RN hours per resident day (HPRD) on weekends are scored independently of weekday staffing. Agency/pool staff ratios affect the staffing star calculation — facilities that rely heavily on registry staff score lower than those with consistent employed staffing.
Survey Deficiency Pattern Analysis
Survey deficiency patterns are predictable. Facilities that received infection control deficiencies in one survey cycle are at elevated risk for similar citations in the next. Vizier analyzes deficiency history and correlates it with current operational metrics to identify survey readiness risks.
