Problem:
Mountain View hospital has adopted a standard cost accounting system for evaluation and control of nursing labor. Diagnosis related groups (DGRS) instituted by the U.S. government for health insurance reimbursement, are used as the output measure in the standard cost system. A DRG is a patient classification scheme that perceives hospitals to be multiproduct firms where inpatient treatment procedures are related to the numbers and types of patient aliments treated. Mountain View Hospital has developed standard nursing times for the treatment of each DRG classification, and nursing labor hours are assumed to vary with the number of DRG’s treated within a time period.
The nursing unit on the fourth floor treats patients with four DRG classifications. The unit is staffed with registered nurses (RNS). licensed practical nurses (LPNs), and aides. The standard nursing hours and salary rates are as follows:
