Staffing & Workforce

Direct-care staffing is the strongest operational driver of quality in nursing homes. Values are hours per resident per day, derived from payroll-based journal (PBJ) submissions. "Case-mix" adjusts for resident acuity; "Adjusted" is the CMS rating-input value.

Health Inspections

CMS weights three inspection cycles to compute the Health Inspection rating: the most recent (50%), the second most recent (33%), and the oldest (17%). Each standard-survey deficiency is assigned a score based on scope and severity; complaint-survey findings and revisit scores are added to produce the cycle total.

Cycle Date Total defs. Standard Complaint Deficiency score Revisits Total score
Cycle 1 (most recent) 2025-05-23 7 7 0 36 1 36
Cycle 2/3 (prior) 2024-06-20 3 3 0 12 1 12
Total weighted health score

Deficiencies (12)

Individual survey findings. Scope/severity uses the CMS A–L matrix: letters further down the alphabet indicate greater harm and wider scope, up through J–L (immediate jeopardy).

2 A/B/C No actual harm — minor
10 D/E/F Actual harm — potential for minor
