Screening programmes involve the systematic offer of testing for populations or groups of apparently healthy people to identify individuals who may be at future risk of a particular medical condition or disease, with the aim of offering intervention to reduce their risk. For many years, screening was practised without debate, and without evidence, but in the 1960s serious challenges were raised about many of the screening procedures then being practised. Benefits and harms of screening must be measured in high quality trials, and the benefits of screening must be weighed alongside the negative side-effects. Concerns were raised about potential and actual harm arising when people without a health problem received dangerous and unnecessary investigations and treatments as a result of routine screening tests. Controversy raged, and it took some 50 years to achieve widespread recognition that evidence-based and quality assured programme delivery was essential, coupled with provision of balanced informed to enable informed choice for potential participants. Commercially motivated provision of poor quality and non-evidence based screening tests is increasing and screening remains a highly contested topic that has relevance in all health systems including for the general public and media. This book serves as a practical and comprehensive guide to all aspects of screening. Following the international success of the first edition, this second edition brings extensive updates and new case study material. The first section deals with concepts, methods, and evidence, charts the story of screening back to 1861, and covers all aspects of a screening programme and how to research the full consequences. The second section is a practical guide to sound policy-making and to high quality delivery of best value screening. The controversies, paradoxes, uncertainties, and ethical dilemmas of screening are explained, and each chapter is packed with examples, real-life case histories, helpful summary points, and self-test questions. Reference is made to the NHS, a leader in screening, but the primary focus is on universal principles, making the book highly relevant across the globe.

Handbook of Checked Baggage Screening – Advanced Airport Security Operation is a practical guide for project managers and designers embarking on hold-baggage screening developments within the airport environment for the first time. The book clearly explains away any uncertainty about the processes and procedures to be used by the various parties involved within the industry and sets out ‘best practice’ with respect to checked baggage screening design. Valuable lessons can be learned from actual case studies contributed by leading equipment manufacturers on recent 100% hold baggage screening projects. In addition to the all-important security screening of baggage and passengers the book also looks at the following areas associated with airport security, through the use of a detailed structured security check-list evaluation questionnaire. The questionnaire allows airports to assess the state of readiness of their airports and then, using the other chapters, gain an insight regarding which technology will best solve any security gaps. The authors offer a unique perspective through their background and experience. Many of the checked baggage screening procedures and equipment discussed in the book have already been implemented in the UK, with the authors responsible for leading this effort. The combined experience they can offer to the industry world wide is invaluable.

Healthcare providers, consumers, researchers and policy makers are inundated with unmanageable amounts of information, including evidence from healthcare research. It has become impossible for all to have the time and resources to find, appraise and interpret this evidence and incorporate it into healthcare decisions. Cochrane Reviews respond to this challenge by identifying, appraising and synthesizing research-based evidence and presenting it in a standardized format, published in The Cochrane Library (www.thecochranelibrary.com). The Cochrane Handbook for Systematic Reviews of Interventions contains methodological guidance for the preparation and maintenance of Cochrane intervention reviews. Written in a clear and accessible format, it is the essential manual for all those preparing, maintaining and reading Cochrane reviews. Many of the principles and methods described here are appropriate for systematic reviews applied to other types of research and to systematic reviews of interventions undertaken by others. It is hoped therefore that this book will be invaluable to all those who want to understand the role of systematic reviews, critically appraise published reviews or perform reviews themselves.

A presentation of screening techniques, modern technologies, and high-capacity instrumentation for increased productivity in the development and discovery of new drugs, chemical compounds, and targeted delivery of pharmaceuticals. It contains practical applications and examples of strategies in cell-based and cell-free screens as well as homogeneous, fluorescence, chemiluminescence, and radioactive-based technologies.

The WHO consolidated guidelines on tuberculosis. Module 2: screening – systematic screening for tuberculosis disease is an updated and consolidated summary of WHO recommendations on systematic screening for tuberculosis (TB) disease, containing 17 recommendations for populations in which TB screening should be conducted and tools to be used for TB screening. TB screening is strongly recommendations for household and close contacts of individuals with TB, people living with HIV, miners exposed to silica dust, and prisoners. In addition, screening is conditionally recommended for people with risk factors for TB attending health care, and for communities with risk factors for TB and limited access to care (e.g. homeless, urban poor, refugees, migrants). General population screening is recommended in high-burden settings (0.5% prevalence or higher). Symptoms, chest radiography (CXR), and molecular WHO-recommended rapid diagnostic tests for TB are recommended as screening tools for all adults eligible for screening. Computer-aided detection programmes are recommended as alternatives to human interpretation of CXR in settings where trained personnel are scarce. For people living with HIV, C-reactive protein is also a good screening tool. This guideline document is accompanied by an operational handbook, the WHO operational handbook on tuberculosis. Module 2: screening – systematic screening for tuberculosis disease, that presents principles of screening, steps in planning and implementing a screening programme, and algorithm options for screening different populations.

Breast cancer is the leading site of new cancer cases in women. Breast cancer detection is currently primarily based on physical examination by health care professionals, chance findings by women, breast self-examination and mammography used for diagnosis or for routine screening. Early enough detection through mass screening with mammography has been introduced in many countries in the hope that early intervention would lead to reduced mortality and less aggressive treatment. The aim of this publication is to provide an independent, authoritative review of the evidence of the efficacy and effectiveness of breast cancer screening. This will be of value to governments, public health officials and others concerned with policy recommendations for cancer control.
