A report published in this month's issue of the American Journal of Critical Care reveals that fewer nurses in intensive care units (ICU) may lead to more patient complications and higher hospital costs. The study, conducted by Dr. Justin B. Dimick and colleagues from Johns Hopkins University, collected data from 569 patients recovering at dozens of ICU wards.

The results revealed that 240 patients in 25 hospitals were under the care of a limited staff of nurses (one nurse for three or more patients). Analysis determined that these patients were at a higher risk of reintubation. In addition, while reducing the number of nurses saved money in the short run, smaller nursing staffs had greater long-term financial consequences for the hospitals.
