Item Testing Theories of Innovation Diffusion: Analysis of Physicians' Adoption of Electronic Health Records(2015) Cohen, Martin F.; Cohen, Martin F.; Hart, David M.The Health Information Technology for Economic and Clinical Health (HITECH) Act of 2009 authorized numerous federal programs intended to address barriers to adoption of electronic health records (EHRs). This dissertation analyzes national survey data to test and compare the significance of five factors in physician decisions on whether to adopt an EHR: improved information, the cost of adoption, the HITECH financial incentives program, challenges in selecting a specific EHR vendor or product, and operational implementation barriers. This study focuses on physicians in smaller, physician-owned practices, who are an important target of policies to promote EHR adoption. In addition to the traditional binary analysis of adopters versus non-adopters, this research also tests models with three categories of adoption status: 1) using an EHR, 2) in the process of adoption, and 3) not yet in the process of adoption. Key findings include:Item The Adoption of Electronic Medical Records by U.S. Hospitals: An Exploration of Network Methods and ModelsHu, Yinyue; Hu, Yinyue; Schintler, LauraWhy do people adopt innovations at different rate? Studies from the diffusion of innovations and network models suggest that network structure and properties provide good explanations of the influence mechanism about how attitudes and behaviors change. This study investigates the adoption of Electronic Medical Records (EMR) among U.S. hospitals with network methods and models. Three research questions are addressed. First, what is the structure of the networks among hospitals? Second, how does the presence of network contribute to the diffusion of EMR? And third, what network-based policies can accelerate the adoption? The study employs network analysis tools, event history models and agent based modeling to present the structure of the network, its role in the diffusion process and to test different policy scenarios.
