McCullough Hospital uses a job-order costing system to assign costs to Its patlents. Its direct materials Include a variety of ltems such as pharmaceutical drugs, heart valves, artificial hips, and pacemakers. Its direct labor costs (e.g, surgeons, anesthesiologists, radiologists, and nurses) assocleted with specific surgical procedures and tests are traced to individual patients. All other costs, such as depreclation of medical equlpment, Insurance, utllities, Incidental medical supplies, and the labor costs assoclated with around-the clock monitoring of patients are treated as overhead costs Hlstorically, McCullough has used one predetermined overhead rate based on the number of patient-days (each night that a patient spends in the hospital counts as one patient-day) to allocate overhead costs to patients. Recently a member of the hospital's accounting staff has suggested using two predetermined overhead rates (allocated based on the number of patlent-days) to improve the accuracy of the costs allocated to patients. The first overhead rate would Include all overhead costs within the Intensive Care Unit (ICU) and the second overhead rate would include all Other overhead costs.
