Some issues within a nursing home are much more severe than others. Medicare evaluates each problem based on 2 scales: the number of residents affected by a problem and the severity of the potential or actual harm to residents based on the problem. We have color coded the matrix below to make it easier to pick out the more severe problems. In general, orange and red issues related to the treatment of a resident are considered substandard quality of care.
