The resulting decrease in the efficacy of in diagnostics for antibiotics threatens our ability to combat infectious diseases. Rapid, point-of-care tests to identify pathogens and better target the appropriate treatment could greatly improve the use of antibiotics. Yet there are few such tests currently available or being Observatory developed despite the rapid pace of medical innovation. Clearly something is inhibiting bacterial infection Studies Series the much-needed development of new and more convenient diagnostic tools. This study delineates priorities for developing diagnostics to improve antibiotic Implications for policy prescription and use with the goal of managing and curbing the expansion of drug resistance. It calls for new approaches, particularly in the provision of diagnostic devices, and, in doing so, outlines some of the inadequacies in health, science and Edited by policy initiatives that have led to the dearth of such devices. The authors make the case Chantal Morel that there is a clear and urgent need for innovation, not only in the technology of diagnosis, but also in public policy and medical practice to support the availability and Lindsay McClure use of better diagnostic tools. Suzanne Edwards Victoria Goodfellow, Dale Sandberg, Joseph Thomas, Elias Mossialos Thomas, Joseph Dale Sandberg, Victoria Goodfellow, Suzanne Edwards, McClure, Lindsay Morel, Chantal by Edited Victoria Goodfellow This book explores the complexities of the diagnostics market from the perspective of both supply and demand, unearthing interesting bottlenecks, some obvious, some more Dale Sandberg subtle. It calls for a multifaceted and broad policy response, and an overhaul of current Joseph Thomas practice, so that the growth of bacterial resistance can be stemmed.

It brings together a wide range of policy-makers, academics and practitioners to analyse trends in health reform, drawing on experience from across Europe to illuminate policy issues. The Observatory is a partnership hosted by the WHO Regional Office for Europe; which includes the governments of Austria, Belgium, Finland, Ireland, Norway, Slovenia, Sweden, the United Kingdom, and the Veneto Region of Italy; the European Commission; the World Bank; UNCAM (French National Union of Health Insurance Funds); the London School of Economics and Political Science; and the London School of Hygiene & Tropical Medicine. The Observatory has a secretariat in Brussels and it has hubs in London (at LSE and LSHTM) and at the Technical University of Berlin.
