In the United States, the health care sector is 20 years behind in the use of information technology to improve the process of health care delivery as compared to other sectors. Patients have to deliver their data over and over again to every health professional they see. Most health care facilities act as data repositories with limited capabilities of data analysis or data exchange. A remaining challenge is, how do we encourage the use of IT in the health care sector that will improve care coordination, save lives, make patients more involved in decision-making, and save money for the American people? According to Healthy People 2020, several challenges such as making health IT more usable, helping users to adapt to the new uses of health IT, and monitoring the impact of health IT on health care quality, safety, and efficiency, will require multidisciplinary models, new data systems, and abundant research. In this dissertation, I developed and used systems engineering methods to understand the role of new health IT in improving the coordination, safety, and efficiency of health care delivery.
