As the health care industry refines quality assurance and quality impr
ovement standards, the accountability of individual care providers is
intensifying. Care providers work within a system of interdependent ro
les and functions and collaborate to attain the common goal of quality
care. A conceptual model was developed which relates the achievement
of specific outcomes to nurses' independent, dependent, and interdepen
dent roles and functions. Empirical literature was used to identify ou
tcomes associated with nurses' role functions. Outcomes associated wit
h nurses' independent role functions included the prevention of compli
cations, clinical outcomes, knowledge of diseases and treatments, sati
sfaction, and cost outcomes. Outcomes associated with nurses' dependen
t role included adverse incidents which caused problems or prolonged h
ospital stays. Outcomes associated with nurses' interdependent role in
cluded interdisciplinary team functioning.
