NOTE: the rates and populations in the HRR and state tables are lower than those in the hospital tables. The regional study includes chronically ill patients who were not hospitalized during the last two years of life, which has the effect of reducing the per capita rates (since these patients were never hospitalized, they had no hospital utilization and lower physician utilization than hospitalized patients). The populations are lower because the regional study used a 20% sample of patients; the 20% Part B database was required to identify chronically ill patients who were not hospitalized.
