Patient care management provided by healthcare organizations is complex, in
volving many different care providers. The information exchange between pro
viders concerns a varying and considerable number of actors and a high tran
smission load. Based on models, used to characterize specific features of w
ork processes, we propose a new method able to analyze and represent clinic
al communications inside hospitals. Software has been developed, providing
tools for storing and retrieving information resulting from clinical commun
ications. The method, together with data collected in actual situations, ma
y constitute useful tools for health information systems developers.
