The authors present a new multifactorial intensity and complexity of c
are model and meta-paradigm that is designed to examine costs, nursing
work, and the variability in resource use across patients and environ
ments. Relationships were observed among four key variables which incl
uded patient-nursing condition, medical condition, caregiver character
istics and the environment. Patient-nursing complexity and medical com
plexity are commonly measured by nursing diagnosis and DRG or Canadian
case mix groupings (CMG) respectively. The complexities associated wi
th the work environment had been the least previously studied factors.
Environmental complexity factors include both supply and demand dimen
sions: scheduling and coordination of procedures, multiple and long pr
ocedures, and characteristics and composition of the caregiver team.
