This issue of CHP/PCOR's quarterly newsletter, which covers news from the summer 2006 quarter, includes articles about:

• research by CHP/PCOR investigators that influenced the Centers for Disease Control and Prevention to recommend widespread voluntary HIV screening for all Americans ages 13 to 64 -- a significant change from the CDC's previous HIV screening guidelines;
• a CHP/PCOR study on patient safety culture in U.S. hospitals -- the largest effort to date to measure hospitals' safety culture and seek to improve it through an intervention that gets hospital executives out of their offices and on to the hospital floors;
• an early-stage project in which CHP/PCOR is collaborating with the Center on Democracy, Development and the Rule of Law to study the relationship between health interventions, governance and development;
• an evidence report examining the challenges of diagnosing and treating anthrax in children, prepared by the Stanford-UCSF Evidence-based Practice Center; and
• a study by CHP/PCOR fellow Kate Bundorf which found that depending on the definition of "affordability" that is used, health insurance is "affordable" to between one-quarter and three-quarters of the uninsured -- and many of those who can't afford insurance purchase it anyway.

All around the world, societies are experiencing an explosion of organizations and organizing: community clubs, religious groups, social movements, as well as schools, hospitals, businesses and government agencies, increasingly take the form of complex and formal organization. Why? Why is global society recast in this format and why so fiercely?

This book explores various dimensions of the trends of expansion, formalization, and standardization of organizing worldwide by exploring such organizational legacies as accounting, business management, corporate social responsibility, and performance benchmarks. Featuring contributions from prominent academics, the book argues that these processes can be attributed to globalization and to its specific tendencies of universalism, rationalization, and rise of the modern notion of the strongly bounded and purposive social actor.

An application of institutional arguments to global issues, the book will be of interest to academics and researchers of Organization Studies, Sociology, Political Science, and Geography.

Many states have "prudent layperson" mandates that require health plans to reimburse hospitals for emergency department (ED) care delivered to patients who believe that they have symptoms warranting emergency treatment. Increased, and possibly unnecessary, ED use has often been attributed to these policies. We use data from thirty-five states to study relationships between passage of prudent layperson policies in the late 1990s and ED use among the privately insured. None of the analyses show evidence that the mandates are associated with increased use. We conclude that prudent layperson mandates are not associated with increases in ED visits among privately insured patients.

Does quality of care systematically differ among government-owned, private not-for-profit, and for-profit hospitals? A large empirical literature provides conflicting evidence. Through quantitative review of 46 studies since 1990, we find that several study features that can explain divergent results: analytic methods, disease studied, and data sources. For unprofitable care, how studies handle market competition and regional differences account for substantial variation. Policymakers should be aware that differences in results appear to arise predominantly from differences between studies' analytic methods. Moreover, conventional methods of meta-analytic synthesis should be applied with great caution given the considerable overlap among studied hospitals.

This issue of CHP/PCOR's quarterly newsletter, which covers news from the winter 2006 quarter, includes articles about:

• a comprehensive review of worldwide anthrax cases from 1900 to 2005, conducted by CHP/PCOR researchers, which found that timely diagnosis and antibiotic treatment, along with pleural fluid drainage, are key to anthrax patients' survival;
• an early-stage research project in which CHP/PCOR core faculty member Grant Miller is collaborating with an NGO in Bangladesh to study whether villagers' traditional cooking practices are contributing to life-threatening respiratory infections;
• assertions by two CHP/PCOR health policy experts that health-savings accounts -- the cornerstone of President Bush's healthcare agenda -- won't save much money and won't address the fundamental problems of the U.S. healthcare system;
• the Agency for Healthcare Research and Quality's release of the Pediatric Quality Indicators, developed by CHP/PCOR researchers and collaborators. This is the first set of data-analysis tools specifically designed to help hospitals monitor their quality of care for hospitalized children; and
• a roundup of CHP/PCOR's 7th annual retreat, which featured panel discussions on improving healthcare quality, conducting health services research in developing countries, and health systems comparisons across industrialized nations.

This issue of CHP/PCOR's quarterly newsletter, which covers news from the fall 2005 quarter, includes articles about:

• a study concluding that the implantable cardioverter defibrillator -- one of the most expensive medical devices on the market -- is worth its high cost, in appropriate patients, because it prevents sudden cardiac deaths;
• the evolution and broad application of the Quality Indicators, a set of practical tools developed by CHP/PCOR researchers that are used by hundreds of U.S. hospitals, medical groups, health insurers, state health agencies and business coalitions to screen for quality problems;
• a study finding that the Internet can be a valuable tool to help patients with stigmatized illnesses (such as mental illness) find information about and seek treatment for their illness;
• CHP/PCOR-hosted seminars on global health themes, given by Jack Chow of the World Health Organization -- who discussed combating malaria, TB and HIV/AIDS -- and Dean Jamison of the NIH's Fogarty International Center, who discussed evaluating countries' performance on health; and
• a prestigious national award won by two CHP/PCOR trainees at the annual meeting of the Society for Medical Decision Making.

This paper compares the relative efficiency of health care providers in managing patients with severe chronic illnesses over fixed periods of time. To minimize the contribution of differences in severity of illness to differences in care management, we evaluate performance over fixed intervals prior to death for patients who died during a five-year period, 1999-2003. Medicare spending, hospital bed and full-time equivalent (FTE) physician inputs, and utilization varied extensively between regions, among hospitals located within a given region, and among hospitals belonging to a given hospital system. The data point to important opportunities to improve efficiency.

This issue of CHP/PCOR's quarterly newsletter, which covers news from the summer 2005 quarter, includes articles about:

• our new core faculty member Grant Miller, a Harvard-trained health economist with an interest in improving health in developing countries;
• a discussion with center director Alan Garber on key issues and challenges facing the Medicare program;
• the fourth meeting of the Patient Safety Consortium, a group of more than 100 U.S. hospitals taking part in CHP/PCOR research on patient safety culture;
• core faculty member Jay Bhattacharya's research on HIV patients' perceptions of their lifespan as examined through viatical settlement transactions; and
• a research project on technology coverage decisions in the U.S. vs. the U.K., undertaken by Stirling Bryan, a U.K.-based Harkness Fellow in Health Care Policy who is spending the next academic year at CHP/PCOR.
