Chicago Southern, founded in 1954 and located at the edge of the University of Illinois at Chicago
Question:
Chicago Southern, founded in 1954 and located at the edge of the University of Illinois at Chicago Circle, is a privately owned 473 patient bed hospital. Close to upscale, gentrified downtown communities as well as high-rise housing projects, Chicago Southern’s patients represent a wide socioeconomic mix. Facilities include an emergency room, x-ray and lab facilities, a maternity ward, an intensive care unit, and an outpatient surgery unit. The staff consists of 610 employees, including 343 nurses (201 RNs, 99 LPNs, and 43 student nurses). Chicago Southern’s new administrator, Doug Benton, like many hospital administrators, is under pressure from the nursing staff to off-load some of their nonprofessional, primarily housekeeping, duties. Mr. Benton is pleased to do so as Chicago Southern, like most hospitals, finds nurses in short supply. Moreover, the nursing staff represents a large and expensive part of his budget. Any savings here could be substantial. However, Benton believes he should have a work sampling study done to see just what the real mix of nursing duties is and how much is really housekeeping. From his observations, he thinks the mix is probably pretty good, with RNs only spending 15% of their time on housekeeping. He is confident that the hospital’s analyst, Jack Meredith, can, after discussions with him and members of the nursing staff, distinguish between housekeeping tasks and nursing duties. For this study, he tells Meredith, everything that is not housekeeping will be considered nursing.* He does want Meredith’s study to have a 95% confidence level with an error of not more than ± 4%.
DISCUSSION QUESTIONS
1. As the analyst, design a work-sampling plan for this assignment.
2. How large must the sample be?
3. How would Meredith randomize the observations given that different nurses operate differently and that duties change with each shift?
