Morbidity level is defined by the RUB (Resource Utilization Band, ACG Case-Mix System), which identifies 5 categories of morbidity with similar expected health services utilization (1: healthy patients; 2: low level of utilization; 3: moderate level of utilization; 4: high level of utilization; and 5: very high level of utilization). Low level of morbidity corresponds to RUB 1 and 2; moderate level of morbidity to RUB 3; and high level of morbidity to RUB 4 and 5.
