An evaluation of primary-level health care undertaken in Tanzania 1989
-91 found that district health managers felt powerless to address heal
th care performance weaknesses, although the district is the unit to w
hich government management functions have been decentralized. In order
to understand the managers' views, this article analyses the pattern
of decentralization within the health system from their perspective. I
t reviews the historical development of government structures and the
theory and practice of decentralization within Tanzania. The matrix of
accountability for health care has become very confusing, with multip
le and cross-cutting flows of authority within and between levels of t
he system. District health managers have limited authority to take man
agement action, such as managing resources, in ways that would begin t
o address problems of inefficiency and poor quality of care within pri
mary care. District health management also suffers from weak resource
allocation and financial management procedures. The main obstacles pre
venting more effective management are: resource constraints; conflicts
between the demands for central control and local discretion; limited
institutional capacity; and political and cultural influences over th
e implementation of decentralization. Evaluation of past experience su
ggests that future policy influencing the organizational structure of
government health services must be developed cautiously, recognizing t
he critical importance of complementary action to develop both institu
tional capacity and political and economic support for the health syst
em.
