CMS expects 3.25 hours a day for residents as sick as this home's (its case-mix figure). The staffing star compares the two.
Staffing by quarter, from daily payroll records
Every nursing home sends CMS its staff hours for each day (the Payroll Based Journal). Here they are added up by quarter. The latest quarter is the one behind the figures above. In January to March 2026, nursing staff hours per resident were 4.42 on weekdays and 3.71 on weekends, 16% lower on weekends (nationally, weekends ran 15% lower). Contract or agency staff worked 0.6% of nursing hours, against 5.3% nationally. Total nursing hours per resident went from 4.18 in April to June 2025 to 4.22 in January to March 2026.
| Quarter | All nursing staff | Registered nurses | Weekdays | Weekends | Contract staff share | Days with no RN hours | Residents a day |

Hours per resident per day: staff hours in the quarter divided by resident days (the daily census CMS derives from resident assessments). Registered nurses include the director of nursing and RNs with administrative duties; aides include nurse aides in training and medication aides, as in CMS's own staffing measure. How these are calculated.
