Download or read book Latent Error written by Samuel Ghasi and published by Trafford Publishing. This book was released on 2005 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emeka and Barbara had met before but only for a moment. When they ran into each other again eight years later and married, Emeka felt he had married the loveliest and most dependable woman. However, after their daughter, Jyoti, died of sickle cell disease and Emeka discovered he did not have the sickle cell gene; he began to have second thoughts... was Barbara really the epitome of virtue he took her for and if she was not, then, who was the covert father of the girl he had always believed was his daughter...? Latent Error is an ironic story of love ideals and individuality versus the more imperfect facts of actual life. It centres on the "old fashioned" principles of its main character, Emeka Obiora, and how these survive within modern life, having first to deal with the slyness of his friend and housemate Mickey and then with the question of paternity - what is more important, the bloodline or real personal attachment? This allows an affecting discussion of the nature of the bonds between human beings. This is a well-executed piece of writing that presents its ideas in an accessible but thought-provoking way. The narrative flows easily, with good rendition of tension and atmosphere all the way to the ending, while the different motivations of the central characters and the contrasting ways they have of fitting in with the human world are acutely drawn.

This book was released on 2015-12-29 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Getting the right diagnosis is a key aspect of health care - it provides an explanation of a patient's health problem and informs subsequent health care decisions. The diagnostic process is a complex, collaborative activity that involves clinical reasoning and information gathering to determine a patient's health problem. According to Improving Diagnosis in Health Care, diagnostic errors-inaccurate or delayed diagnoses-persist throughout all settings of care and continue to harm an unacceptable number of patients. It is likely that most people will experience at least one diagnostic error in their lifetime, sometimes with devastating consequences. Diagnostic errors may cause harm to patients by preventing or delaying appropriate treatment, providing unnecessary or harmful treatment, or resulting in psychological or financial repercussions. The committee concluded that improving the diagnostic process is not only possible, but also represents a moral, professional, and public health imperative. Improving Diagnosis in Health Care, a continuation of the landmark Institute of Medicine reports To Err Is Human (2000) and Crossing the Quality Chasm (2001), finds that diagnosis-and, in particular, the occurrence of diagnostic errorsâ€"has been largely unappreciated in efforts to improve the quality and safety of health care. Without a dedicated focus on improving diagnosis, diagnostic errors will likely worsen as the delivery of health care and the diagnostic process continue to increase in complexity. Just as the diagnostic process is a collaborative activity, improving diagnosis will require collaboration and a widespread commitment to change among health care professionals, health care organizations, patients and their families, researchers, and policy makers. The recommendations of Improving Diagnosis in Health Care contribute to the growing momentum for change in this crucial area of health care quality and safety.

Download or read book Individual Latent Error Detection I LED written by Justin R.E. Saward and published by CRC Press. This book was released on 2018-12-07 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Undetected human error in aircraft maintenance creates a latent error condition that can contribute to undesirable outcomes. Individual Latent Error Detection (I-LED) acts as an additional system safety control that helps an engineer recall past errors through environmental cues. This book addresses a gap in the human factors research and current safety strategies by exploring the nature and extent of I-LED and its benefit to safety resilience. The book will describe the I-LED concept using a systems perspective and propose practical interventions to be integrated within existing safety systems as an additional control to enhance resilience against human performance variability. Provides a new view of total safety based on enhanced resilience provided through the integration of I-LED interventions within existing safety systems Offers an in-depth exploration of the phenomenon of spontaneous recall of past event, leading to error detection and recovery of latent error conditions Discusses the application of Human Factors methods to conduct real-world observations in maintenance environments Describes the application of the systems view of human error to applied research Presents cost versus benefit analysis of safety interventions targeting latent error conditions

Download or read book Making Healthcare Safe written by Lucian L. Leape and published by Springer Nature. This book was released on 2021-05-28 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique and engaging open access title provides a compelling and ground-breaking account of the patient safety movement in the United States, told from the perspective of one of its most prominent leaders, and arguably the movement’s founder, Lucian L. Leape, MD. Covering the growth of the field from the late 1980s to 2015, Dr. Leape details the developments, actors, organizations, research, and policy-making activities that marked the evolution and major advances of patient safety in this time span. In addition, and perhaps most importantly, this book not only comprehensively details how and why human and systems errors too often occur in the process of providing health care, it also promotes an in-depth understanding of the principles and practices of patient safety, including how they were influenced by today’s modern safety sciences and systems theory and design. Indeed, the book emphasizes how the growing awareness of systems-design thinking and the self-education and commitment to improving patient safety, by not only Dr. Leape but a wide range of other clinicians and health executives from both the private and public sectors, all converged to drive forward the patient safety movement in the US. Making Healthcare Safe is divided into four parts: I. In the Beginning describes the research and theory that defined patient safety and the early initiatives to enhance it. II. Institutional Responses tells the stories of the efforts of the major organizations that began to apply the new concepts and make patient safety a reality. Most of these stories have not been previously told, so this account becomes their histories as well. III. Getting to Work provides in-depth analyses of four key issues that cut across disciplinary lines impacting patient safety which required special attention. IV. Creating a Culture of Safety looks to the future, marshalling the best thinking about what it will take to achieve the safe care we all deserve. Captivatingly written with an “insider’s” tone and a major contribution to the clinical literature, this title will be of immense value to health care professionals, to students in a range of academic disciplines, to medical trainees, to health administrators, to policymakers and even to lay readers with an interest in patient safety and in the critical quest to create safe care.

Download or read book Total Survey Error in Practice written by Paul P. Biemer and published by John Wiley & Sons. This book was released on 2017-02-21 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Featuring a timely presentation of total survey error (TSE), this edited volume introduces valuable tools for understanding and improving survey data quality in the context of evolving large-scale data sets This book provides an overview of the TSE framework and current TSE research as related to survey design, data collection, estimation, and analysis. It recognizes that survey data affects many public policy and business decisions and thus focuses on the framework for understanding and improving survey data quality. The book also addresses issues with data quality in official statistics and in social, opinion, and market research as these fields continue to evolve, leading to larger and messier data sets. This perspective challenges survey organizations to find ways to collect and process data more efficiently without sacrificing quality. The volume consists of the most up-to-date research and reporting from over 70 contributors representing the best academics and researchers from a range of fields. The chapters are broken out into five main sections: The Concept of TSE and the TSE Paradigm, Implications for Survey Design, Data Collection and Data Processing Applications, Evaluation and Improvement, and Estimation and Analysis. Each chapter introduces and examines multiple error sources, such as sampling error, measurement error, and nonresponse error, which often offer the greatest risks to data quality, while also encouraging readers not to lose sight of the less commonly studied error sources, such as coverage error, processing error, and specification error. The book also notes the relationships between errors and the ways in which efforts to reduce one type can increase another, resulting in an estimate with larger total error. This book: • Features various error sources, and the complex relationships between them, in 25 high-quality chapters on the most up-to-date research in the field of TSE • Provides comprehensive reviews of the literature on error sources as well as data collection approaches and estimation methods to reduce their effects • Presents examples of recent international events that demonstrate the effects of data error, the importance of survey data quality, and the real-world issues that arise from these errors • Spans the four pillars of the total survey error paradigm (design, data collection, evaluation and analysis) to address key data quality issues in official statistics and survey research Total Survey Error in Practice is a reference for survey researchers and data scientists in research areas that include social science, public opinion, public policy, and business. It can also be used as a textbook or supplementary material for a graduate-level course in survey research methods.

Download or read book A Human Error Approach to Aviation Accident Analysis written by Douglas A. Wiegmann and published by Routledge. This book was released on 2017-12-22 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human error is implicated in nearly all aviation accidents, yet most investigation and prevention programs are not designed around any theoretical framework of human error. Appropriate for all levels of expertise, the book provides the knowledge and tools required to conduct a human error analysis of accidents, regardless of operational setting (i.e. military, commercial, or general aviation). The book contains a complete description of the Human Factors Analysis and Classification System (HFACS), which incorporates James Reason's model of latent and active failures as a foundation. Widely disseminated among military and civilian organizations, HFACS encompasses all aspects of human error, including the conditions of operators and elements of supervisory and organizational failure. It attracts a very broad readership. Specifically, the book serves as the main textbook for a course in aviation accident investigation taught by one of the authors at the University of Illinois. This book will also be used in courses designed for military safety officers and flight surgeons in the U.S. Navy, Army and the Canadian Defense Force, who currently utilize the HFACS system during aviation accident investigations. Additionally, the book has been incorporated into the popular workshop on accident analysis and prevention provided by the authors at several professional conferences world-wide. The book is also targeted for students attending Embry-Riddle Aeronautical University which has satellite campuses throughout the world and offers a course in human factors accident investigation for many of its majors. In addition, the book will be incorporated into courses offered by Transportation Safety International and the Southern California Safety Institute. Finally, this book serves as an excellent reference guide for many safety professionals and investigators already in the field.

Download or read book Behind Human Error written by David Woods and published by CRC Press. This book was released on 2017-09-18 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human error is cited over and over as a cause of incidents and accidents. The result is a widespread perception of a 'human error problem', and solutions are thought to lie in changing the people or their role in the system. For example, we should reduce the human role with more automation, or regiment human behavior by stricter monitoring, rules or procedures. But in practice, things have proved not to be this simple. The label 'human error' is prejudicial and hides much more than it reveals about how a system functions or malfunctions. This book takes you behind the human error label. Divided into five parts, it begins by summarising the most significant research results. Part 2 explores how systems thinking has radically changed our understanding of how accidents occur. Part 3 explains the role of cognitive system factors - bringing knowledge to bear, changing mindset as situations and priorities change, and managing goal conflicts - in operating safely at the sharp end of systems. Part 4 studies how the clumsy use of computer technology can increase the potential for erroneous actions and assessments in many different fields of practice. And Part 5 tells how the hindsight bias always enters into attributions of error, so that what we label human error actually is the result of a social and psychological judgment process by stakeholders in the system in question to focus on only a facet of a set of interacting contributors. If you think you have a human error problem, recognize that the label itself is no explanation and no guide to countermeasures. The potential for constructive change, for progress on safety, lies behind the human error label.

Download or read book Distracted Doctoring written by Peter J. Papadakos and published by Springer. This book was released on 2017-07-31 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examining-room computers require doctors to record detailed data about their patients, yet reduce the time clinicians can spend listening attentively to the very people they are trying to help. This book presents original essays by distinguished experts in their fields, addressing this critical problem and making an urgent case for reform, because while electronic technology has revolutionized the practice of medicine, it also poses a unique challenge to health care. Smartphones in the hands of doctors and nurses have become dangerously seductive devices that can endanger their patients. Distracted Doctoring is written for anesthesiologists and surgeons, as well as general practitioners, nurses, and health care administrators and students. Chapters include Electronic Challenges to Patient Safety and Care; Distraction, Disengagement, and the Purpose of Medicine; and Managing Distractions through Advocacy, Education, and Change.

Download or read book The Blame Machine Why Human Error Causes Accidents written by Robert Whittingham and published by Taylor & Francis. This book was released on 2004-02-18 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Blame Machine describes how disasters and serious accidents result from recurring, but potentially avoidable, human errors. It shows how such errors are preventable because they result from defective systems within a company. From real incidents, you will be able to identify common causes of human error and typical system deficiencies that have led to these errors. On a larger scale, you will be able to see where, in the organisational or management systems, failure occurred so that you can avoid them. The book also describes the existence of a 'blame culture' in many organisations, which focuses on individual human error whilst ignoring the system failures that caused it. The book shows how this 'blame culture' has, in the case of a number of past accidents, dominated the accident enquiry process hampering a proper investigation of the underlying causes. Suggestions are made about how progress can be made to develop a more open culture in organisations, both through better understanding of human error by managers and through increased public awareness of the issues. The book brings together documentary evidence from recent major incidents from all around the world and within the Rail, Water, Aviation, Shipping, Chemical and Nuclear industries. Barry Whittingham has worked as a senior manager, design engineer and consultant for the chemical, nuclear, offshore oil and gas, railway and aviation sectors. He developed a career as a safety consultant specializing in the human factors aspects of accident causation. He is a member of the Human Factors in Reliability Group, and a Fellow of the Safety and Reliability Society.

Book excerpt: "This volume is dedicated to creating a single source that both summarizes what we know regarding errors in organizations and provide a focused effort toward identifying future directions for research. The goal is to provide a forum for researchers who have conducted a considerable amount of research in the error domain to discuss how to extend this research, and provide researchers who have not considered the implications of errors for their domain of organizational research an outlet to do so"--

Download or read book Risk Based Thinking written by Tony Muschara and published by Routledge. This book was released on 2017-11-13 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Society at large tends to misunderstand what safety is all about. It is not just the absence of harm. When nothing bad happens over a period of time, how do you know you are safe? In reality, safety is what you and your people do moment by moment, day by day to protect assets from harm and to control the hazards inherent in your operations. This is the purpose of risk-based thinking, the key element of the six building blocks of Human and Organizational Performance (H&OP). Generally, H&OP provides a risk-based approach to managing human performance in operations. But, specifically, risk-based thinking enables foresight and flexibility—even when surprised—to do what is necessary to protect assets from harm but also achieve mission success despite ongoing stresses or shocks to the operation. Although you cannot prepare for every adverse scenario, you can be ready for almost anything. When risk-based thinking is integrated into the DNA of an organization’s way of doing business, people will be ready for most unexpected situations. Eventually, safety becomes a core value, not a priority to be negotiated with others depending on circumstances. This book provides a coherent perspective on what executives and line managers within operational environments need to focus on to efficiently and effectively control, learn, and adapt.

Download or read book Guidelines for Preventing Human Error in Process Safety written by CCPS (Center for Chemical Process Safety) and published by John Wiley & Sons. This book was released on 2010-08-13 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost all the major accident investigations--Texas City, Piper Alpha, the Phillips 66 explosion, Feyzin, Mexico City--show human error as the principal cause, either in design, operations, maintenance, or the management of safety. This book provides practical advice that can substantially reduce human error at all levels. In eight chapters--packed with case studies and examples of simple and advanced techniques for new and existing systems--the book challenges the assumption that human error is "unavoidable." Instead, it suggests a systems perspective. This view sees error as a consequence of a mismatch between human capabilities and demands and inappropriate organizational culture. This makes error a manageable factor and, therefore, avoidable.

Download or read book Measurement Error and Latent Variables in Econometrics written by T. Wansbeek and published by North Holland. This book was released on 2000-12-08 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book first discusses in depth various aspects of the well-known inconsistency that arises when explanatory variables in a linear regression model are measured with error. Despite this inconsistency, the region where the true regression coeffecients lies can sometimes be characterized in a useful way, especially when bounds are known on the measurement error variance but also when such information is absent. Wage discrimination with imperfect productivity measurement is discussed as an important special case. Next, it is shown that the inconsistency is not accidental but fundamental. Due to an identification problem, no consistent estimators may exist at all. Additional information is desirable. This information can be of various types. One type is exact prior knowledge about functions of the parameters. This leads to the CALS estimator. Another major type is in the form of instrumental variables. Many aspects of this are discussed, including heteroskedasticity, combination of data from different sources, construction of instruments from the available data, and the LIML estimator, which is especially relevant when the instruments are weak. The scope is then widened to an embedding of the regression equation with measurement error in a multiple equations setting, leading to the exploratory factor analysis (EFA) model. This marks the step from measurement error to latent variables. Estimation of the EFA model leads to an eigenvalue problem. A variety of models is reviewed that involve eignevalue problems as their common characteristic. EFA is extended to confirmatory factor analysis (CFA) by including restrictions on the parameters of the factor analysis model, and next by relating the factors to background variables. These models are all structural equation models (SEMs), a very general and important class of models, with the LISREL model as its best-known representation, encompassing almost all linear equation systems with latent variables. Estimation of SEMs can be viewed as an application of the generalized method of moments (GMM). GMM in general and for SEM in particular is discussed at great length, including the generality of GMM, optimal weighting, conditional moments, continuous updating, simulation estimation, the link with the method of maximum likelihood, and in particular testing and model evaluation for GMM. The discussion concludes with nonlinear models. The emphasis is on polynomial models and models that are nonlinear due to a filter on the dependent variables, like discrete choice models or models with ordered categorical variables.
