Providence Hospital generates monthly performance reports for each of its departments. The hospital must maintain an adequate staff of attending and on-call physicians at all times, so physician costs are not affected by the number of patient visits. But all other costs do vary with patient activity, Nurse-hours are used as the activity measure for nursing costs and patientists are used as the activity measure for the cost of supplies and other variable costs. The head physcan of the hospitals emergency room, Yolanda Mortensen, is responsible for control of costs. During October, the emergency room unit expected to treat 3.700 patients but actually treated 3,600 patients.
