The study, which appears in the May/June 2010 issue of Journal of the American Medical Informatics Association, also reports on the initial assessment of that framework by health information exchange experts across the nation.
"This work is important, because the framework will help those engaged in health information exchange around the country measure the value of NHIN services to patients and health-care providers as well as to the national health-care reform goals of quality, safety, cost and efficiency," said the study's first author Brian Dixon, M.P.A., a Regenstrief program manager and a doctoral candidate in health informatics at the Indiana University School of Informatics at Indiana University-Purdue University Indianapolis.
The Regenstrief framework also will help the nation track the development and utilization of health information exchange and the array of NHIN services currently under development with support from the Office of the National Coordinator for Health Information Technology (ONC) and U.S. Department of Health and Human Services (HHS).
"Historically novel health care information technologies have been underutilized, restricting their impact on quality of care and patient safety. This new framework will help policymakers understand its value not only in terms of quality and safety but also how widespread data exchange is being used in clinical practice. This will help answer the question of whether the national health information network envisioned by the federal government is a bridge to nowhere or a public utility that is making a difference in improving health care," said Dixon.
Regenstrief created and operates the Indiana Network for Patient Care (INPC), one of the highest volume health information exchanges in the United States. The INPC daily handles approximately 2.5 million secure transactions of clinically relevant data such as laboratory test results, medication and treatment histories, and other clinically important information in a standardized, electronic format. This information is critical to diagnoses, treatment and referral decisions. The INPC membership includes hospitals, physician practices, clinical laboratories, radiology centers, as well as rehabilitation and long term care facilities throughout Indiana.
"The new Regenstrief framework will help health information exchange developers and researchers improve efforts to measure the value that these services provide their members and communities. Locally, we will use the framework to measure how the INPC and the NHIN provide value to Hoosiers in terms of quality, safety, cost and efficiency. We hope the framework can serve as a catalyst for other communities as well to perform similar evaluations of health information exchange," said J. Marc Overhage, M.D., Ph.D., director of medical informatics at the Regenstrief Institute, Regenstrief Professor of Medicine at the Indiana University School of Medicine, and president and C.E.O. of the Indiana Health Information Exchange
The Regenstrief Institute has been an international leader in the development, implementation and evaluation of health information technology and health information standards for over three decades. Regenstrief investigators are leaders in the development of clinical data standards and health care system interoperability. The institute is located in Indianapolis, the most health-wired metropolitan area in the country.
The study, also co-authored by Atif Zafar, M.D. of the IU School of Medicine and the Regenstrief Institute, was funded by the Regenstrief Institute.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
