Changes related to care delivery patterns.

Nurse administrators, faced with a need to increase productivity and reduce costs in response to lower inpatient volumes and increased competition, are restructuring systems of care delivery. A survey of acute care hospitals was conducted to determine the extent of changes in nursing care delivery models, skill mix, assignment of non-nursing personnel to the nursing department, use of unlicensed assistive personnel, and registered nurse role changes in healthcare delivery systems employing unlicensed personnel.
