The Centers for Disease Control and Prevention (CDC), in coordination
with 65 states, cities, and territories, implemented HN prevention com
munity planning beginning in 1994. This large scale innovation in publ
ic health planning has involved tens of thousands of professionals and
community residents. Though a single case study, Michigan provides a
strong test of the implementation of this national prevention planning
model because of the state's decentralized approach to HIV prevention
community planning involving several hundred residents. A decentraliz
ed approach to community planning promises to maximize participation a
nd the sharing of leadership as well as obstacles to community plannin
g. Here, the CDC Guidance for community planning is contrasted with em
pirical observation of implementation in Michigan. We conclude that th
e high expectations for a decentralized approach to HIV prevention com
munity planning can be best achieved when a distinction is drawn betwe
en information-seeking tasks and decision-making tasks. We recommend t
hat information-seeking tasks be centrally coordinated, and that decis
ion-making tasks be decentralized, to most fully achieve the potential
of HN prevention community planning.
