Keeping Up with the Jones’: Influence from Peer Hospitals on EMR Diffusion
Corey M. Angst and Ritu Agarwal

This study, positioned at the inter-organizational level, draws upon research in the adoption and diffusion of innovations to predict the likelihood of EMR adoption by hospitals. Likelihood of EMR adoption is driven by organizational factors such as the presence, concentration, and experience with complementary HIT; and an environmental factor, spatial proximity, reflecting the presence of contagion from physically proximate facilities that have adopted EMRs. A hazard model is fitted to data from a sample drawn from a multi-year survey spanning 1970 to 2004 of almost 4,000 hospitals. We find interesting and surprising geographic variations in EMR adoption.

The Missing Link: Electronic Health Record Adoption by Physician Practices
Catherine Anderson, Abhay Mishra, Ritu Agarwal, Corey M. Angst and Steve Labkoff

This study investigates various aspects of introducing electronic health record systems (EHRS) into physician practices ranging from perceptions of value to practice-level implications. Specific goals of this project are: 1) to understand the facilitators and inhibitors of EHRS adoption and use in medical practices in the US, 2) to understand the practice-level implications of EHRS adoption and use, 3) to inform policy making about the use of EHR adoption. We use survey data from over 270 practices or varying sizes to isolate the specific factors that are most predictive of EHR adoption.

Using Annotations from Controlled Vocabularies to Find Patterns in Life Science Links
Louiqa Raschid, Woei-Jyh Lee, Padmini Srinivasan, Daniel L. Rubin and Nigam Shah

The Life Science Link methodology provides users with a set of tools to explore the rich Web of interconnected and annotated objects in multiple repositories, and to identify meaningful patterns. These instances represent a background dataset of knowledge. We then identify those associations of pairs of CV terms that are potentially significant and may lead to new knowledge. We develop an approach to determine a confidence level and support in the associations between the pairs of CV terms.

State-Level HIT Activity and Themes
Corey M. Angst, Anuj Desai and Jennifer Wulff

This focuses on state level health information technology (HIT) activities. It examines: (1) how active individual states are in the HIT domain, (2) specific themes in HIT activity, and (3) states that are influential in, or catalysts for HIT adoption. We found increasing state-level HIT activity and earmarked funding and resources to support their efforts. Several states emerged as leaders, offering innovative plans for implementing electronic health records (EHRs) and demonstrating political leadership for these initiatives.

Early Findings on Personal Health Records and Individual Use
Corey M. Angst and Ritu Agarwal

In this study, we explore an emergent IT application – the electronic personal health record (PHR) that arguably, offers the same potential for revolutionary, discontinuous change in the healthcare sector. We conducted an exploratory empirical study to understand the characteristics of individuals who are early adopters of PHR software. We also sought to understand what type of value individuals perceive in the PHR, and the drivers of their usage intentions. We found three distinct perceived components of value: (1) compliance, (2) connectedness, and (3) convenience. We also found that different demographic and medical condition variables influence the type of value a user sees in a PHR. Finally, our results show that future intentions to use a PHR are driven by perceptions that the PHR provides compliance and improves a patient’s relationship and connectedness with their healthcare provider.

With Help From Strangers: Social Support and Smoking Cessation in Technology-Mediated Communities
Jessie Ma and Ritu Agarwal

This study draws upon prior research in social support and social learning to hypothesize that smoking cessation outcomes can be predicted by the structural social support (i.e., quantity) and functional social support (i.e., quality) provided to the individual in the online community. We measure structural social support by the individual’s tenure in the community and the size of their social network, i.e., the number of community members they interact with. Functional social support is assessed by information need fulfillment, group identification, and identity consonance. Empirical findings from a study of participants on Quitnet.com provide support for the valuable and powerful effects of social support from other online community members, i.e., virtual “strangers”. Implications for the design of online communities for social support related to wellness are discussed.

Electronic Health Records: Will privacy concerns hinder adoption?
Corey M. Angst and Ritu Agarwal

Privacy concerns can inhibit the adoption of EHRs. We draw from literature on attitude formation and change to develop hypotheses that individuals can be persuaded to support the use and ultimately adopt EHRs, even in the presence of significant privacy concerns if arguments about the value of EHRs are framed properly. Using a pseudo-experimental methodology, we assess the impact of privacy concerns on the relationship between argument framing, issue involvement, attitude and likelihood of adoption. The study yields important implications for the design of awareness campaigns related to EHRs.
