Influences on nursing care volume.

Abstract

This study explores influences on nursing care volume per case in four DRGs and five hospitals. After accounting for the effects of length of stay, patient characteristics, and severity of illness, the direct effect of factors describing the nursing staff and hospital was assessed. Skill mix and standing orders each were significant in one or more DRGs, but there was no significant association between the volume of nursing care and occupancy or staff availability. The management and research implications of the findings are discussed.
