In this paper we assess the value of electronic health care information exchange and interoperability (HIEI) between providers (hospitals and medical group practices) and independent laboratories, radiology centers, pharmacies, payers, public health departments, and other providers. We have created an HIEI taxonomy and combined published evidence with(More)
We surveyed regional health information organizations (RHIOs) to assess the state of electronic health information exchange in the United States. We found fifty-five operational RHIOs, and most were focused on exchanging test results. Forty-one percent of operational RHIOs reported receiving sufficient revenue from participating entities to cover operating(More)
OBJECTIVES To determine the proportion of US hospitals engaged in health information exchange (HIE) with unaffiliated providers and to identify key hospital-level and market-level factors associated with participating in exchange. STUDY DESIGN Using the 2009 American Hospital Association Information Technology survey, supplemented by Dartmouth Atlas, Area(More)
Electronic clinical data exchange promises substantial financial and societal benefits, but it is unclear whether and when it will become widespread. In early 2007 we surveyed 145 regional health information organizations (RHIOs), the U.S. entities working to establish data exchange. Nearly one in four was likely defunct. Only twenty efforts were of at(More)
The national effort to promote the adoption and meaningful use of electronic health records (EHRs) is well under way. However, 2014 marks an important transition: For many hospitals, penalties will be assessed in fiscal year 2015 for failing to meet federal meaningful-use criteria by the end of fiscal year 2014. We used recent data from the American(More)
OBJECTIVE To estimate costs and benefits for Australia of implementing health information exchange interoperability among health care providers and other health care stakeholders. DESIGN A cost-benefit model considering four levels of interoperability (Level 1, paper based; Level 2, machine transportable; Level 3, machine readable; and Level 4, machine(More)
THE UNITED STATES IS UNDERTAKING AN AMBITIOUS EFfort to wire the health care system. The goal is to build a nationwide information infrastructure to serve as the foundation for large and sustained improvements in performance. Widespread adoption of health information technology will support new care delivery models, such as patient-centered medical homes,(More)
Telehealth is widely believed to hold great potential to improve access to, and increase the value of, health care. Gaining a better understanding of why some hospitals adopt telehealth technologies while others do not is critically important. We examined factors associated with telehealth adoption among US hospitals. Data from the Information Technology(More)
While health IT is thought to be critical to the success of new models of care delivery, we know little about the extent to which those pursuing these models are relying on HIT. We studied a large patient-centered medical home (PCMH) demonstration project, a new model of care delivery that has received substantial policy attention, in order to assess which(More)
OBJECTIVE To determine the financial and clinical benefits of implementing information technology (IT)-enabled disease management systems. RESEARCH DESIGN AND METHODS A computer model was created to project the impact of IT-enabled disease management on care processes, clinical outcomes, and medical costs for patients with type 2 diabetes aged >25 years(More)
