Download or read book Sharing Clinical Trial Data written by Institute of Medicine and published by National Academies Press. This book was released on 2015-04-20 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data sharing can accelerate new discoveries by avoiding duplicative trials, stimulating new ideas for research, and enabling the maximal scientific knowledge and benefits to be gained from the efforts of clinical trial participants and investigators. At the same time, sharing clinical trial data presents risks, burdens, and challenges. These include the need to protect the privacy and honor the consent of clinical trial participants; safeguard the legitimate economic interests of sponsors; and guard against invalid secondary analyses, which could undermine trust in clinical trials or otherwise harm public health. Sharing Clinical Trial Data presents activities and strategies for the responsible sharing of clinical trial data. With the goal of increasing scientific knowledge to lead to better therapies for patients, this book identifies guiding principles and makes recommendations to maximize the benefits and minimize risks. This report offers guidance on the types of clinical trial data available at different points in the process, the points in the process at which each type of data should be shared, methods for sharing data, what groups should have access to data, and future knowledge and infrastructure needs. Responsible sharing of clinical trial data will allow other investigators to replicate published findings and carry out additional analyses, strengthen the evidence base for regulatory and clinical decisions, and increase the scientific knowledge gained from investments by the funders of clinical trials. The recommendations of Sharing Clinical Trial Data will be useful both now and well into the future as improved sharing of data leads to a stronger evidence base for treatment. This book will be of interest to stakeholders across the spectrum of research-from funders, to researchers, to journals, to physicians, and ultimately, to patients.
Download or read book Small Clinical Trials written by Institute of Medicine and published by National Academies Press. This book was released on 2001-01-01 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clinical trials are used to elucidate the most appropriate preventive, diagnostic, or treatment options for individuals with a given medical condition. Perhaps the most essential feature of a clinical trial is that it aims to use results based on a limited sample of research participants to see if the intervention is safe and effective or if it is comparable to a comparison treatment. Sample size is a crucial component of any clinical trial. A trial with a small number of research participants is more prone to variability and carries a considerable risk of failing to demonstrate the effectiveness of a given intervention when one really is present. This may occur in phase I (safety and pharmacologic profiles), II (pilot efficacy evaluation), and III (extensive assessment of safety and efficacy) trials. Although phase I and II studies may have smaller sample sizes, they usually have adequate statistical power, which is the committee's definition of a "large" trial. Sometimes a trial with eight participants may have adequate statistical power, statistical power being the probability of rejecting the null hypothesis when the hypothesis is false. Small Clinical Trials assesses the current methodologies and the appropriate situations for the conduct of clinical trials with small sample sizes. This report assesses the published literature on various strategies such as (1) meta-analysis to combine disparate information from several studies including Bayesian techniques as in the confidence profile method and (2) other alternatives such as assessing therapeutic results in a single treated population (e.g., astronauts) by sequentially measuring whether the intervention is falling above or below a preestablished probability outcome range and meeting predesigned specifications as opposed to incremental improvement.

Book excerpt: This is an open access title available under the terms of a CC BY-NC 4.0 International licence. It is free to read at Oxford Scholarship Online and offered as a free PDF download from OUP and selected open access locations. Before new interventions are released into disease control programmes, it is essential that they are carefully evaluated in field trials'. These may be complex and expensive undertakings, requiring the follow-up of hundreds, or thousands, of individuals, often for long periods. Descriptions of the detailed procedures and methods used in the trials that have been conducted have rarely been published. A consequence of this, individuals planning such trials have few guidelines available and little access to knowledge accumulated previously, other than their own. In this manual, practical issues in trial design and conduct are discussed fully and in sufficient detail, that Field Trials of Health Interventions may be used as a toolbox' by field investigators. It has been compiled by an international group of over 30 authors with direct experience in the design, conduct, and analysis of field trials in low and middle income countries and is based on their accumulated knowledge and experience. Available as an open access book via Oxford Medicine Online, this new edition is a comprehensive revision, incorporating the new developments that have taken place in recent years with respect to trials, including seven new chapters on subjects ranging from trial governance, and preliminary studies to pilot testing.
Download or read book The Prevention and Treatment of Missing Data in Clinical Trials written by National Research Council and published by National Academies Press. This book was released on 2010-12-21 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Randomized clinical trials are the primary tool for evaluating new medical interventions. Randomization provides for a fair comparison between treatment and control groups, balancing out, on average, distributions of known and unknown factors among the participants. Unfortunately, these studies often lack a substantial percentage of data. This missing data reduces the benefit provided by the randomization and introduces potential biases in the comparison of the treatment groups. Missing data can arise for a variety of reasons, including the inability or unwillingness of participants to meet appointments for evaluation. And in some studies, some or all of data collection ceases when participants discontinue study treatment. Existing guidelines for the design and conduct of clinical trials, and the analysis of the resulting data, provide only limited advice on how to handle missing data. Thus, approaches to the analysis of data with an appreciable amount of missing values tend to be ad hoc and variable. The Prevention and Treatment of Missing Data in Clinical Trials concludes that a more principled approach to design and analysis in the presence of missing data is both needed and possible. Such an approach needs to focus on two critical elements: (1) careful design and conduct to limit the amount and impact of missing data and (2) analysis that makes full use of information on all randomized participants and is based on careful attention to the assumptions about the nature of the missing data underlying estimates of treatment effects. In addition to the highest priority recommendations, the book offers more detailed recommendations on the conduct of clinical trials and techniques for analysis of trial data.

Download or read book Running Behavioral Studies With Human Participants written by Frank E. Ritter and published by SAGE. This book was released on 2013 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: A practical, concrete road map to running research studies with human subjects. Covering both conceptual and practical issues critical to implementing a study with human participants, this book is organized to follow the standard process in experiment-based research, covering such issues as potential ethical problems, risks to validity, experimental setup, running a study, and concluding a study. The detailed guidance on each step of a study is ideal for anyone who has had little or no previous practical training in research methodology. The book's examples and sample forms are drawn from areas such as cognitive psychology, human factors, human-computer interaction, and human-robotic interaction. Key Features A coherent view of how to implement the experimental process, including detailed discussions of the setup and running of behavioral studies, gives you a practical guide for implementing your own experiments. Concrete examples speak to the diverse needs of the HCl, human factors, cognitive science, and related communities. Practical coverage of risks and problems that can be anticipated and avoided helps you recognize the ethical challenges you might encounter during the course of designing, running, or concluding a study. Three running example scenarios drawn from industrial and academic settings help you understand the major themes of each chapter. Example forms provide you with models you can use as you create your own experimental documents (such as IRB applications, experimental scripts, consent forms, and room layouts) to meet your particular research needs. Practical advice and examples of challenges associated with experimental setup and execution (such as how to set up experimental rooms, manage late or missing participants, and devise an effective experimental script) humanize key points in a memorable way, helping you recall the major points of the book. Built-in learning aids include further readings, an appendix on running studies online, questions at the end of each chapter, and publication paths and types that encourage you to take ownership of the research process and engage in research in a directed and methodical way.

Download or read book Fundamentals of Clinical Trials written by Lawrence M. Friedman and published by Springer Science & Business Media. This book was released on 2010-09-09 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The clinical trial is “the most definitive tool for evaluation of the applicability of clinical research.” It represents “a key research activity with the potential to improve the quality of health care and control costs through careful comparison of alternative treatments” [1]. It has been called on many occasions, “the gold st- dard” against which all other clinical research is measured. Although many clinical trials are of high quality, a careful reader of the medical literature will notice that a large number have deficiencies in design, conduct, analysis, presentation, and/or interpretation of results. Improvements have occurred over the past few decades, but too many trials are still conducted without adequate attention to its fundamental principles. Certainly, numerous studies could have been upgraded if the authors had had a better understanding of the fundamentals. Since the publication of the first edition of this book, a large number of other texts on clinical trials have appeared, most of which are indicated here [2–21]. Several of them, however, discuss only specific issues involved in clinical trials. Additionally, many are no longer current. The purpose of this fourth edition is to update areas in which major progress has been made since the publication of the third edition. We have revised most chapters considerably and added one on ethical issues.

Download or read book Returning Individual Research Results to Participants written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-08-23 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: When is it appropriate to return individual research results to participants? The immense interest in this question has been fostered by the growing movement toward greater transparency and participant engagement in the research enterprise. Yet, the risks of returning individual research resultsâ€"such as results with unknown validityâ€"and the associated burdens on the research enterprise are competing considerations. Returning Individual Research Results to Participants reviews the current evidence on the benefits, harms, and costs of returning individual research results, while also considering the ethical, social, operational, and regulatory aspects of the practice. This report includes 12 recommendations directed to various stakeholdersâ€"investigators, sponsors, research institutions, institutional review boards (IRBs), regulators, and participantsâ€"and are designed to help (1) support decision making regarding the return of results on a study-by-study basis, (2) promote high-quality individual research results, (3) foster participant understanding of individual research results, and (4) revise and harmonize current regulations.
Download or read book Responsible Research written by Institute of Medicine and published by National Academies Press. This book was released on 2003-02-06 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: When 18-year-old Jesse Gelsinger died in a gene transfer study at the University of Pennsylvania, the national spotlight focused on the procedures used to ensure research participants' safety and their capacity to safeguard the well-being of those who volunteer for research studies. Responsible Research outlines a three-pronged approach to ensure the protection of every participant through the establishment of effective Human Research Participant Protection Programs (HRPPPs). The approach includes: Improved research review processes, Recognition and integration of research participants' contributions to the system, and Vigilant maintenance of HRPPP performance. Issues addressed in the book include the need for in-depth, complimentary reviews of science, ethics, and conflict of interest reviews; desired qualifications for investigators and reviewers; the process of informed consent; federal and institutional oversight; and the role of accreditation. Recommendations for areas of key interest include suggestions for legislative approaches, compensation for research-related injury, and the refocusing of the mission of institutional review boards. Responsible Research will be important to anyone interested in the issues that are relevant to the practice of using human subjects as research participants, but especially so to policy makers, research administrators, investigators, and research sponsorsâ€"but also including volunteers who may agree to serve as research participants.
Download or read book Virtual Clinical Trials written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-11-16 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful drug development relies on accurate and efficient clinical trials to deliver the best and most effective pharmaceuticals and clinical care to patients. However, the current model for clinical trials is outdated, inefficient and costly. Clinical trials are limited by small sample sizes that do not reflect variations among patients in the real world, financial burdens on participants, and slow processes, and these factors contribute to the disconnect between clinical research and clinical practice. On November 28-29, the National Academies of Sciences, Engineering, and Medicine convened a workshop to investigate the current clinical trials system and explore the potential benefits and challenges of implementing virtual clinical trials as an enhanced alternative for the future. This publication summarizes the presentations and discussions from the workshop.

Download or read book Psychological Responses to Violations of Expectations Perspectives and Answers from Diverse Fields of Psychology written by Mario Gollwitzer and published by Frontiers Media SA. This book was released on 2018-03-19 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Pavlov's dog expecting food when hearing a bell to stereotypes as expectations about other people’s behaviour, from Bandura’s self-efficacy as expectation for success and failure of one’s own behaviour to the "predictive brain" concept in current perception theories: expectations have been a central construct in different areas of psychological research. In each of these areas, specific concepts, theoretical approaches, and empirical methods have been developed to explain when and why expectations persist and when they do not. Many theories assume that expectations are likely to change in the face of disconfirming evidence. However, sometimes expectations persist even though they are empirically violated, suggesting that they can be “sticky” under certain circumstances. But what are these circumstances? And what are the psychological mechanisms that can explain why and when expectations persist or change after being confronted with expectation-violating evidence? Each contribution of the current book offers insights into individuals’ reactions to violations of expectations. They show that many pieces of the puzzle have been collected in the many sub-displiclines of psychology and that putting them together in an integrative fashion stays a fascinating enterprise.
Download or read book Interoception Contemplative Practice and Health written by Norman Farb and published by Frontiers Media SA. This book was released on 2017-02-07 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an emergent movement of scientists and scholars working on somatic awareness, interoception and embodiment. This work cuts across studies of neurophysiology, somatic anthropology, contemplative practice, and mind-body medicine. Key questions include: How is body awareness cultivated? What role does interoception play for emotion and cognition in healthy adults and children as well as in different psychopathologies? What are the neurophysiological effects of this cultivation in practices such as Yoga, mindfulness meditation, Tai Chi and other embodied contemplative practices? What categories from other traditions might be useful as we explore embodiment? Does the cultivation of body awareness within contemplative practice offer a tool for coping with suffering from conditions, such as pain, addiction, and dysregulated emotion? This emergent field of research into somatic awareness and associated interoceptive processes, however, faces many obstacles. The principle obstacle lies in our 400-year Cartesian tradition that views sensory perception as epiphenomenal to cognition. The segregation of perception and cognition has enabled a broad program of cognitive science research, but may have also prevented researchers from developing paradigms for understanding how interoceptive awareness of sensations from inside the body influences cognition. The cognitive representation of interoceptive signals may play an active role in facilitating therapeutic transformation, e.g. by altering context in which cognitive appraisals of well-being occur. This topic has ramifications into disparate research fields: What is the role of interoceptive awareness in conscious presence? How do we distinguish between adaptive and maladaptive somatic awareness? How do we best measure somatic awareness? What are the consequences of dysregulated somatic/interoceptive awareness on cognition, emotion, and behavior? The complexity of these questions calls for the creative integration of perspectives and findings from related but often disparate research areas including clinical research, neuroscience, cognitive psychology, anthropology, religious/contemplative studies and philosophy.
