In a study of administrative costs in US hospitals, Woolhandler et al.
reviewed 1990 Medicare cost reports from 6400 hospitals. The intent o
f this study was to determine the validity of previous administrative
cost estimate studies in Californian hospitals, which were extrapolate
d nationwide. The study found that hospital administrative costs range
d from 20.5 (in Minnesota) to 30.6% (in Hawaii) of each hospital's spe
nding. Furthermore, the investigators found that these administrative
costs did not vary according to the level of managed care penetration
in a particular US state. Using a health maintenance organisation (HMO
) enrolment rate of 20% as the median, the study found hospital admini
strative costs to be similar to states with an HMO enrolment rate of <
20%. The authors concluded that reducing hospital administrative costs
to the Canadian level (9 to 11% of total hospital spending) would res
ult in annual savings of $US50 billion. Thus, the authors suggest that
if administrative costs are high, US healthcare reform should follow
a system similar to that used in Canada.
