Download or read book Finding What Works in Health Care written by Institute of Medicine and published by National Academies Press. This book was released on 2011-07-20 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthcare decision makers in search of reliable information that compares health interventions increasingly turn to systematic reviews for the best summary of the evidence. Systematic reviews identify, select, assess, and synthesize the findings of similar but separate studies, and can help clarify what is known and not known about the potential benefits and harms of drugs, devices, and other healthcare services. Systematic reviews can be helpful for clinicians who want to integrate research findings into their daily practices, for patients to make well-informed choices about their own care, for professional medical societies and other organizations that develop clinical practice guidelines. Too often systematic reviews are of uncertain or poor quality. There are no universally accepted standards for developing systematic reviews leading to variability in how conflicts of interest and biases are handled, how evidence is appraised, and the overall scientific rigor of the process. In Finding What Works in Health Care the Institute of Medicine (IOM) recommends 21 standards for developing high-quality systematic reviews of comparative effectiveness research. The standards address the entire systematic review process from the initial steps of formulating the topic and building the review team to producing a detailed final report that synthesizes what the evidence shows and where knowledge gaps remain. Finding What Works in Health Care also proposes a framework for improving the quality of the science underpinning systematic reviews. This book will serve as a vital resource for both sponsors and producers of systematic reviews of comparative effectiveness research.

This book was released on 2017-07-21 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: As many medical and healthcare researchers have a love-hate relationship with statistics, the second edition of this practical reference book may make all the difference. Using practical examples, mainly from the authors' own research, the book explains how to make sense of statistics, turn statistical computer output into coherent information, and help decide which pieces of information to report and how to present them. The book takes you through all the stages of the research process, from the initial research proposal, through ethical approval and data analysis, to reporting on and publishing the findings. Helpful tips and information boxes, offer clear guidance throughout, including easily followed instructions on how to: -develop a quantitative research proposal for ethical/institutional approval or research funding -write up the statistical aspects of a paper for publication -choose and perform simple and more advanced statistical analyses -describe the statistical methods and present the results of an analysis. This new edition covers a wider range of statistical programs - SAS, STATA, R, and SPSS, and shows the commands needed to obtain the analyses and how to present it, whichever program you are using. Each specific example is annotated to indicate other scenarios that can be analysed using the same methods, allowing you to easily transpose the knowledge gained from the book to your own research. The principles of good presentation are also covered in detail, from translating relevant results into suitable extracts, through to randomised controlled trials, and how to present a meta-analysis. An added ingredient is the inclusion of code and datasets for all analyses shown in the book on our website (http://medical-statistics.info). Written by three experienced biostatisticians based in the UK and US, this is a step-by-step guide that will be invaluable to researchers and postgraduate students in medicine, those working in the professions allied to medicine, and statisticians in consultancy roles.

Download or read book Redesigning the Process for Establishing the Dietary Guidelines for Americans written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-12-16 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: What foods should Americans eat to promote their health, and in what amounts? What is the scientific evidence that supports specific recommendations for dietary intake to reduce the risk of multifactorial chronic disease? These questions are critically important because dietary intake has been recognized to have a role as a key determinant of health. As the primary federal source of consistent, evidence-based information on dietary practices for optimal nutrition, the Dietary Guidelines for Americans (DGA) have the promise to empower Americans to make informed decisions about what and how much they eat to improve health and reduce the risk of chronic disease. The adoption and widespread translation of the DGA requires that they be universally viewed as valid, evidence-based, and free of bias and conflicts of interest to the extent possible. However, this has not routinely been the case. A first short report meant to inform the 2020 review cycle explored how the advisory committee selection process can be improved to provide more transparency, eliminate bias, and include committee members with a range of viewpoints. This second and final report recommends changes to the DGA process to reduce and manage sources of bias and conflicts of interest, improve timely opportunities for engagement by all interested parties, enhance transparency, and strengthen the science base of the process.

Download or read book Optimizing the Process for Establishing the Dietary Guidelines for Americans written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-12-16 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Federal guidance on nutrition and diet is intended to reflect the state of the science and deliver the most reliable recommendations possible according to the best available evidence. This guidance, updated and presented every 5 years in the Dietary Guidelines for Americans (DGA), serves as the basis for all federal nutrition policies and nutrition assistance programs, as well as nutrition education programs. Despite the use of the guidelines over the past 30 years, recent challenges prompted Congress to question the process by which food and nutrition guidance is developed. This report assesses the process used to develop the guidelines; it does not evaluate the substance or use of the guidelines. As part of an overall, comprehensive review of the process to update the DGA, this first report seeks to discover how the advisory committee selection process can be improved to provide more transparency, eliminate bias, and include committee members with a range of viewpoints for the purpose of informing the 2020 cycle.

Download or read book Dietary Reference Intakes for Sodium and Potassium written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-08-26 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: As essential nutrients, sodium and potassium contribute to the fundamentals of physiology and pathology of human health and disease. In clinical settings, these are two important blood electrolytes, are frequently measured and influence care decisions. Yet, blood electrolyte concentrations are usually not influenced by dietary intake, as kidney and hormone systems carefully regulate blood values. Over the years, increasing evidence suggests that sodium and potassium intake patterns of children and adults influence long-term population health mostly through complex relationships among dietary intake, blood pressure and cardiovascular health. The public health importance of understanding these relationships, based upon the best available evidence and establishing recommendations to support the development of population clinical practice guidelines and medical care of patients is clear. This report reviews evidence on the relationship between sodium and potassium intakes and indicators of adequacy, toxicity, and chronic disease. It updates the Dietary Reference Intakes (DRIs) using an expanded DRI model that includes consideration of chronic disease endpoints, and outlines research gaps to address the uncertainties identified in the process of deriving the reference values and evaluating public health implications.

Download or read book Advances in Meta Analysis written by Terri Pigott and published by Springer Science & Business Media. This book was released on 2012-01-31 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of the book is advanced statistical analyses for quantitative research synthesis (meta-analysis), and selected practical issues relating to research synthesis that are not covered in detail in the many existing introductory books on research synthesis (or meta-analysis). Complex statistical issues are arising more frequently as the primary research that is summarized in quantitative syntheses itself becomes more complex, and as researchers who are conducting meta-analyses become more ambitious in the questions they wish to address. Also as researchers have gained more experience in conducting research syntheses, several key issues have persisted and now appear fundamental to the enterprise of summarizing research. Specifically the book describes multivariate analyses for several indices commonly used in meta-analysis (e.g., correlations, effect sizes, proportions and/or odds ratios), will outline how to do power analysis for meta-analysis (again for each of the different kinds of study outcome indices), and examines issues around research quality and research design and their roles in synthesis. For each of the statistical topics we will examine the different possible statistical models (i.e., fixed, random, and mixed models) that could be adopted by a researcher. In dealing with the issues of study quality and research design it covers a number of specific topics that are of broad concern to research synthesists. In many fields a current issue is how to make sense of results when studies using several different designs appear in a research literature (e.g., Morris & Deshon, 1997, 2002). In education and other social sciences a critical aspect of this issue is how one might incorporate qualitative (e.g., case study) research within a synthesis. In medicine, related issues concern whether and how to summarize observational studies, and whether they should be combined with randomized controlled trials (or even if they should be combined at all). For each topic, included is a worked example (e.g., for the statistical analyses) and/or a detailed description of a published research synthesis that deals with the practical (non-statistical) issues covered.

Download or read book Nutrition Research Concepts Applications written by Karen Eich Drummond and published by Jones & Bartlett Learning. This book was released on 2017-02-09 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrition Research: Concepts & Applications is written for nutrition students in undergraduate and graduate programs who are beginning to develop the skills necessary to become knowledgeable research consumers, conduct and document research projects, and understand how to use research findings in practice. The first text of its kind to clearly explain each section of a research paper to students who are new at the process, this title outlines how to read and analyze research by learning concepts, such as sampling design or relative risk, and then seeing these abstract ideas brought to life in actual research articles. Students also apply these concepts in Application Questions and Critical Thinking Exercises in which they write abstracts, answer questions about evidenced-based study data, or use a checklist to critique a study. Students also learn the nuts and bolts of searching databases for appropriate articles, using systematic reviews such as the Academy of Nutrition and Dietetics

Download or read book A National Strategy to Reduce Food Waste at the Consumer Level written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-10-14 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 30 percent of the edible food produced in the United States is wasted and a significant portion of this waste occurs at the consumer level. Despite food's essential role as a source of nutrients and energy and its emotional and cultural importance, U.S. consumers waste an estimated average of 1 pound of food per person per day at home and in places where they buy and consume food away from home. Many factors contribute to this wasteâ€"consumers behaviors are shaped not only by individual and interpersonal factors but also by influences within the food system, such as policies, food marketing and the media. Some food waste is unavoidable, and there is substantial variation in how food waste and its impacts are defined and measured. But there is no doubt that the consequences of food waste are severe: the wasting of food is costly to consumers, depletes natural resources, and degrades the environment. In addition, at a time when the COVID-19 pandemic has severely strained the U.S. economy and sharply increased food insecurity, it is predicted that food waste will worsen in the short term because of both supply chain disruptions and the closures of food businesses that affect the way people eat and the types of food they can afford. A National Strategy to Reduce Food Waste at the Consumer Level identifies strategies for changing consumer behavior, considering interactions and feedbacks within the food system. It explores the reasons food is wasted in the United States, including the characteristics of the complex systems through which food is produced, marketed, and sold, as well as the many other interconnected influences on consumers' conscious and unconscious choices about purchasing, preparing, consuming, storing, and discarding food. This report presents a strategy for addressing the challenge of reducing food waste at the consumer level from a holistic, systems perspective.
