This study investigates factors associated with the adoption of corpor
ate restructuring by hospitals in Massachusetts, where restructuring o
ccurred much more rapidly than it did nationally. Drawing on studies o
f management innovation in hospitals, this article hypothesizes that e
arly adopters will differ from those that adopt later on the basis of
individual and organizational factors, and that institutional forces w
ill explain later adoption. The findings show no differences between e
arly and later adopters but do show that after an intense period of re
structuring, hospitals became less likely to adopt the innovation. The
article concludes with a discussion of the impact of reimbursement la
ws on the adoption pattern and the implications for the diffusion of m
anagement innovation, particularly under health care reform.
