The data behind Nursing Home View

Learn about the data behind our ratings.

Nursing Home View data source

Nursing Home View uses nursing home data from the U.S. Centers for Medicare & Medicaid Services (CMS). The CCMS reports quality ratings and metrics for nursing homes that participate in Medicare or Medicaid. These ratings and metrics are provided on an overall basis and on three specific domains: health inspections, staffing, and quality measures.

Health inspections

Ratings for the health inspection domain are based on the number, scope, and severity of deficiencies identified during the three most recent annual inspection surveys, as well as substantiated findings from the most recent 36 months of complaint investigations. All deficiency findings are weighted by scope and severity. This measure also takes into account the number of revisits required to ensure that deficiencies identified during the health inspection survey have been corrected.


Ratings on the staffing domain are based on two measures: 1) Registered nurse (RN) hours per resident per day; and 2) total nurse staffing (the sum of RN, licensed practical nurse (LPN), and nurse aide) hours per resident per day. Other types of nursing home staff, such as clerical or housekeeping staff, are not included in the staffing rating calculation.

The staffing measures are derived from data submitted each quarter through the Payroll-Based Journal (PBJ) System, along with daily resident census derived from Minimum Data Set, Version 3.0 (MDS 3.0) assessments, and are case-mix adjusted based on the distribution of MDS 3.0 assessments by Resource Utilization Groups, version IV (RUG-IV group). In addition to the overall staffing rating, a separate rating for RN staffing is also reported.

Quality measures

Ratings for the quality measures are based on performance on 15 of the QMs that are currently posted on the Nursing Home Compare website. These include nine long-stay measures and six short-stay measures. Note that not all of the quality measures that are reported on Nursing Home Compare are included in the rating calculations. In addition to an overall quality of resident care rating, separate ratings for the quality of resident care for short-stay residents and long-stay residents are also reported.
