This paper examines the extent to which hospitals and physicians use n
ew organizational structures designed to facilitate contracting with m
anaged care firms and the extent to which this use is associated with
managed care revenue. The data come from a nationally representative s
ample of 1,495 U.S. community hospitals responding to a 1993 survey ab
out different organizational structures. The results indicate that onl
y 23.3 percent of hospitals participate in at least one form. Hospital
s with more than 15 percent of revenues from managed care are twice as
likely to participate and favor forms that provide tighter linkages w
ith physicians.
