Network Graph Analysis of Hospital and Health Services Functional Structures

Hospitals and health services are complicated places that generate large quantities of data focusing on individual patient care. That care is the product of multiple interactions between patients and the many differently staffs within a hospital or health service. It is hard to use the data produced by hospitals and health services to adequately represent those interactions and use them to identify how services work in practice. We present a set of proof-of-concept studies that represent health systems as networks, analysed by contemporary network graph theory, to look for interpretable patterns of interactions that reveal modular functional structures at multiple levels within large general hospitals.
