Diseases caused by multidrug-resistant bacteria are a serious problem in modern healthcare systems, increasing both mortality and cost of healthcare. Our aim is to create a network of hospitals which represents real transfer of patients, so that the effectiveness of prevention strategies can be measured.
In the talk I will first present a network model based on the dataset and determine the importance of inter-hospital transfers in the evolution of prevalence of pathogen in hospitals and in the community. Then I will shortly describe one of the provided hospitalization dataset. Next I will stratificate patients according to infection risk assigning them into two groups: highly susceptible to the diseases and those who are more immune. The differences between representatives of these groups will be explored in detail. I will focus on percentage change of high-risk patients within each hospital and propose certain categories of facilities based on their characteristics.
Finally, I will introduce model describing transmission of the bacteria in the network of two hospitals and present some of its features. For a special choice of parameters this model can be used to describe the dynamics of transmission in a single hospital, in which we single out ICU, and in corresponding community.
