Health System Modeling and Simulation : Coordinated Care Example

The RTSync team is awarded a grant from National Science Foundation (NSF) to conduct research on Health System Modeling and Simulation : Coordinated Care Example in 2013.


Health care spending in the United States is highly disproportionate, with half of health care dollars spent on five percent of the population. Accountable Care Organizations (ACO)s that manage this at risk population coordinate the care of patients who need special attention after leaving the doctor's office or the hospital because they cannot carry out the activities required to complete their care. The ability to provide the right information to the right people in real time, requires a system-level model that identifies the various community partners involved and rigorously lays out how their interactions might be effectively coordinated to improve care for the neediest patients that cost the most. RTSync develops a systems-level simulation model that takes account of emerging health information networks and electronic medical records, and integrates system concepts and agent modeling concepts extended to include human behavioral limitations. This will provide a basis for developing and testing architectures for health care services with application to coordinated care systems as examples. The model will be based on a coordinated care framework developed by the Rockville Institute and validated against data obtained from an actual application to care coordination of pregnant women at risk for having low-birth weight babies.


This work will integrate systems and agent concepts to meet the challenge posed by the workshop, viz. to develop a framework for modeling and simulation of health care at the system of systems level. Such integration advances our knowledge of how to incorporate both human and non-human behavioral elements within the same systems framework. This will show how to systematically model the behaviors of patients who require coordinated care interventions, thus rendering these behaviors amenable to health care system design and engineering. The proposers bring together decades of experience in systems modeling and simulation as well as appreciation for the challenges in integrating health care component systems in to an affordable system offering high quality care to its consumers.


The systems-based modeling and simulation framework developed in this work will be applicable more broadly to coordination problems in today's information-technology-based business, engineering, and military systems. System-level modeling and simulation is increasingly the only workable alternative to build and test alternative architectures for coordination of component systems prior to implementation. The tool set employed to build the model to be demonstrated will be widely distributed through the efforts of RTSync to transfer its modeling and simulation technology to the market place as well as by the Rockville Institute in promulgating its coordinated care approaches to organizations set up to provide such care.
