Major organizational changes among hospitals, like system affiliation,
merger, and closure, would seem to offer substantial opportunities fo
r hospitals and health systems to be strategic in the local reconfigur
ation of health services. This report presents the results of a unique
survey on what happened to hospitals after mergers occurring between
1983 and 1988, inclusive. Building on an ongoing verification process
of the American Hospital Association, surviving institutions from all
74 mergers that occurred during the study frame were surveyed in the f
all of 1991. Responses were received from 60 of the 74 mergers (81%),
regarding the primary, postmerger use of the hospitals involved. Topic
s surveyed included the premerger competition between the hospitals an
d in their environment, and what happened to the hospitals after their
mergers. Mergers frequently served to convert acute, inpatient capaci
ty to other functions, with less than half of acquired hospitals conti
nuing acute services after merger. In the context of health care refor
m, mergers may offer an expeditious way locally to restructure health
services. Evidence on the postmerger uses of hospitals and about the r
easons given for merger suggests that mergers may reflect two general
strategies: elimination of direct acute competitors or expansion of ac
ute care networks.
