Analysis of nursing costs in the intensive care unit.

The specific aims of this study were to: (1) describe nursing costs for patients having a stay in the intensive care unit (ICU), with respect to severity of illness, length of stay (LOS), operative status, and age; (2) determine the relationship between these patient factors and nursing costs for patients having an ICU stay, and (3) analyze the variance in per diem nursing costs using these patient factors. The convenience sample comprised 437 patients admitted to the surgical and medical intensive care units at the University of Michigan Hospital. Patients who were older, had longer ICU stays, higher severity of illness scores, or undergone surgery, were found to incur significantly higher nursing costs. Severity of illness alone accounted for 35 percent of the nursing cost variation. ICU length of stay and post-operative status contributed significantly to the variation in nursing costs after taking into account patient severity. The distribution of total nursing costs was extremely skewed, with five percent of patients incurring 33 percent of total nursing costs during the study period. The results of the study indicate a need to continue efforts to disaggregate nursing cost variation and to examine its relationship with severity and other patient characteristics.Ph.D.NursingUniversity of Michiganhttp://deepblue.lib.umich.edu/bitstream/2027.42/161864/1/8812993.pd
