Dynamic Contact Network Analysis in Hospital Wards

Participants : Christophe Crespelle, Eric Fleury, Lucie Martinet.

We analysed a huge and very precise trace of contact data collected during 6 months on the entire population of a rehabilitation hospital. We investigated the graph structure of the average daily contact network, and we unveiled striking properties of this structure in the considered hospital, as a very strong introversion of services, the key role of the contacts between patients and staff in connecting those introverted services all together, and very different pattern of contacts during one day between patients and staffs. The methodology we designed to lead these analysis is very general and can be applied for analysing any dynamic complex network where nodes are classified into groups. Those results are part of Lucie Martinet's PhD thesis.
