Clinical trials have two purposes -- to treat the patients in the trial, and to obtain information which increases our understanding of the disease and especially how patients respond to treatment. Statistical design provides a means to achieve both these aims, while statistical data analysis provides methods for extracting useful information from the trial data. Recent advances in statistical computing have enabled statisticians to implement very rapidly a broad array of methods which previously were either impractical or impossible. Biostatisticians are now able to provide much greater support to medical researchers working in both clinical and laboratory settings. As our collective toolkit of techniques for analyzing data has grown, it has become increasingly difficult for biostatisticians to keep up with all the developments in our own field. Recent Advances in Clinical Trial Design and Analysis brings together biostatisticians doing cutting-edge research and explains some of the more recent developments in biostatistics to clinicians and scientists who work in clinical trials.

The assessment of patient reported outcomes and health-related quality of life continue to be rapidly evolving areas of research and this new edition reflects the development within the field from an emerging subject to one that is an essential part of the assessment of clinical trials and other clinical studies. The analysis and interpretation of quality-of-life assessments relies on a variety of psychometric and statistical methods which are explained in this book in a non-technical way. The result is a practical guide that covers a wide range of methods and emphasizes the use of simple techniques that are illustrated with numerous examples, with extensive chapters covering qualitative and quantitative methods and the impact of guidelines. The material in this new third edition reflects current teaching methods and content widened to address continuing developments in item response theory, computer adaptive testing, analyses with missing data, analysis of ordinal data, systematic reviews and meta-analysis. This book is aimed at everyone involved in quality-of-life research and is applicable to medical and non-medical, statistical and non-statistical readers. It is of particular relevance for clinical and biomedical researchers within both the pharmaceutical industry and clinical practice.

The rubric "Quality of Life" first came to the explicit attention of the medical profession a little over thirty years ago. Despite the undoubted fact that each one of us has his or her own Quality of Life, be it good or bad, there is still no general agreement about its definition, or the manner in which it should be evaluated. Although much has been written about quality of life, this work has been largely concerned with population-based studies, especially in health policy & health economics. The importance of individual quality of life has been neglected, in part because of a failure to define quality of life itself with sufficient care, in part perhaps because of a belief that it is impossible to develop a meaningful method of measuring individual variables. It is a fundamental belief of the editors of this book that the primary focus of quality of life is & must continue to be the individual, who alone can define it & assess its changing personal significances. The individual perspective is of vital importance not only to patients but to their doctors too, & is more & more frequently proposed as the most meaningful measure of outcome in clinical research, especially in non-remitting or chronic conditions. Workers who wish to consider wider aspects of influences on the illnesses suffered by individuals & the health care that they receive will find much to stimulate them in the methods of documentation proposed in this book. Those mainly concerned with population samples rather than individuals may also find the sensitive methods of investigation proposed here not only to be applicable to their own areas of interest, but also rewarding in perhaps unexpected ways.

ABSTRACT: Helping patients achieve an optimal quality of life through patient-centered treatment planning should be the ultimate goal of all oral health care providers. However, this issue extends beyond the realm of the individual clinician's office. This text presents quality-of-life research from various fields, including psychology, public health, and general health care; discusses how a patient-centered approach can be applied to basic oral and craniofacial research, clinical dental practice, community dental health issues, and dental education; and addresses how oral health-related quality of life relates to treating and understanding different patient populations, such as children with special needs, medically compromised patients, patients with oral cancer, and patients with chronic facial pain. Also discussed is how factors such as race/ethnicity, gender, and age can affect oral health-related quality-of-life concerns and treatment strategies. Finally, the book offers an outlook on the role that oral health-related quality of life will play in future research and dental education.

The aim of this encyclopedia is to provide a comprehensive reference work on scientific and other scholarly research on the quality of life, including health-related quality of life research or also called patient-reported outcomes research. Since the 1960s two overlapping but fairly distinct research communities and traditions have developed concerning ideas about the quality of life, individually and collectively, one with a fairly narrow focus on health-related issues and one with a quite broad focus. In many ways, the central issues of these fields have roots extending to the observations and speculations of ancient philosophers, creating a continuous exploration by diverse explorers in diverse historic and cultural circumstances over several centuries of the qualities of human existence. What we have not had so far is a single, multidimensional reference work connecting the most salient and important contributions to the relevant fields. Entries are organized alphabetically and cover basic concepts, relatively well established facts, lawlike and causal relations, theories, methods, standardized tests, biographic entries on significant figures, organizational profiles, indicators and indexes of qualities of individuals and of communities of diverse sizes, including rural areas, towns, cities, counties, provinces, states, regions, countries and groups of countries.

The EUROHIS project has focused on the comparability of health surveys and has uncovered some problems that arise when aiming to compare data from different countries. Similar problems of cross-cultural comparability also arise when comparing data from other sources, such as health registers, and are just as complex and difficult to tackle. One of the main advantages of health surveys, however, is the relatively low cost and time involved in adapting them according to the needs of health policy-makers. This work shows that the output from the EUROHIS project provides common instruments for the measurement of eight health indicators. The development of these instruments has required careful consideration of relevant common concepts and how these should be defined and operationalized. The instruments are freely available for use by all countries, with the aim of enhancing national health information systems and facilitating cross-national comparisons of health data.

It was over five years ago that the Centre for Medicines Research organized a workshop entitled "Quality of Life: Assessment and Application". This workshop brought together a unique group of participants, some of whom had been involved in studies on quality of life for well over a decade, whilst others were meeting the subject for the first time. This blend of experienced researchers and enthusiastic newcomers was a great stimulus to the discus sions which followed individual presentations as well as that resulting from the study groups. In the ensuing publication, a balance was sought between a consideration of the complex principles underlying the assessment of quality of life and the application of such assessments to specific clinical conditions which necessitated this approach. The organization in 1991 of a second workshop entitled "Quality of Life Assessment: Key Issues in the 1990s" resulted in a further consideration of the quality of life philosophy, concepts and key instruments together with an update on assessing quality of life in a number of major disease areas. Of particular importance was an examination of various viewpoints concerned with ethical questions and their implications, and quality oflife from industry, regulatory and health care purchasers' perspectives. As a result of this second workshop, the editors of the original book referred to above decided to produce a second edition with a number of updates and additional chapters.

This new edition provides the essential clinical guidance both for those embarking upon a career in palliative medicine and for those already established in the field. A team of international experts here distil what every practitioner needs to know into a practical and reliable resource.

Considerable data and expertise have accumulated in the assessment of quality of life, but to date this assessment has largely been restricted to the devel- ment of instruments that are used only in the setting in which they were dev- oped. The chapters of this book, taken together, apply this expertise to a re- tively new area: international quality of life assessment, that is to say, consid- ing quality of life from an international perspective, and developing methods for the assessment of quality of life that can be used in more than one cultural setting. The World Health Organization (WHO) initiatives in the area of inter- tional quality of life assessment arose for several compelling reasons. The World Health Organization has a commitment to equitable and accessible health care for all. This commitment refers not only to health in its narrow sense of the absence of disease and impairment, but to health as astate of physical, mental and social well-being. Disease and impairment affect not just the physical domain of life but also a person's psychological state, level of - dependence and social relationships. This is a reality not yet fully reflected in health care settings. The broadening in focus in the measurement of health to include indicators which address this more holistic sense of health is a welcome emerging trend. The primary aim of any health intervention is to maximise health and minimise disease, thereby enhancing patients' quality of life.
