ABC, Resource Drivers, Service Industry Glencoe Medical Clinic operates a cardiology care unit and a maternity care unit. Cara Abadi, the clinic's administrator, is investigating the charges assigned to cardiology patients. Currently, all cardiology patients are charged the same rate per patient day for daily care services. Doily care services are broadly defined as occupancy, feeding, and nursing care. A recent study, however, revealed several interesting outcomes. First, the demands patients place on daily care services vary with the severity of the case being treated. Second, the occupancy activity is a combination of two activities: lodging and use of monitoring equipment. Since some patients require more monitoring than others, these activities should be separated. Third, the daily rate should reflect the difference in demands resulting from differences in patient type. Separating the occupancy activity into two separate activities also required the determination of the cost of each activity. Determining the costs of the monitoring activity was fairly easy because its costs were directly traceable. Lodging costs, however, are shared by two activities: lodging cardiology patients and lodging maternity care patients. The total lodging costs for the two activities were $5,766,000 per year and consisted of such items as building depreciation, building maintenance, and building utilities. The cardiology floor and the maternity floor each occupy 18,000 square feet. Abadi determined that lodging costs would be assigned to each unit based on square feet. To compute a daily rate that reflected the difference in demands, patients were placed in three categories according to illness severity, and the following annual data were collected:
