1. Describe the purpose and features of the old cost and billing system at Cambridge Hospital. 2. Why did Cambridge hospital undertake the ABC study? 3. Is the PCU the best place to conduct the study? Why or why not? 4. What does the study tell us about the costs of using nurse practitioners, physicians, internr'residents, and interpreters to conduct services?1 5. Which type of service and provider are the most and least profitable for the PCU? Why? 6. It appears that the ABC team has not taken into account all of the nurse practitioners' time. Assuming that the nurse practitioner worked 36 hours per week and 50 weeks per year, recalculate the nurse practitioner exam and translation wait time activity driver rates. Assume that the mix between patient minutesfyear and employee minutesi'year for the nurse practitioner given in Exhibit 8 is valid and that there is 7 minutes of interpretive service wait time for every 60 minutes of nonemployee exam time. You can take the costs accumulated in various cost pools in Exhibit 7 as correct. 7. Using the same format as in Exhibit 10, create a product cost matrix for the nurse practitioner visits, assuming they spend 45 minutes of wait time for each interpreted visit. 8. Suggest steps for cost containment at the PCU
