The UK has more than five years experience of the introduction of pati
ent based management information systems into acute hospitals. These s
ystems support the measurement of activity, process of care and cost o
f care allowing linkage of management processes of the hospital to dir
ect treatment and care of individual patients. An implicit 'product' m
odel for acute hospital care underlies these systems. When considering
the management information needs of community health providers, the l
imitations of this model became apparent and highlighted the need for
a more general model. The paper suggests such a model, not only approp
riate for community care but also a better model for hospital services
.
