We have made 3 significant improvements to the Five Star Nursing Home Quality Rating System:

  1. Incorporated the 2 nursing home quality measures for antipsychotic use into the Quality Measure Rating.
  2. Increased the number of points necessary to earn a Quality Measure Star Rating of 2 or more stars.
  3. Changed the scoring method for the Staffing star rating. Nursing homes must earn a 4-star rating on either the RN or total Staffing rating to achieve an overall Staffing rating of 4-stars.

Many nursing homes will see a lower quality measure rating as a result of these changes, even though the underlying QM data may not have changed. Because of these changes, it is not appropriate to compare a facility's QM ratings that appear in February with those that appeared in earlier months.
