Book Description
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.

Rare Conditions, Diagnostic Challenges, and Controversies in Clinical Neuropsychology
Author: Jessica Fish
Publisher: Taylor & Francis
ISBN: 100088564X
Category : Psychology
Languages : en
Pages : 400
Book Description
This book highlights those rare, difficult to diagnose or controversial cases in contemporary clinical neuropsychology. The evidence base relevant to this type of work is almost by definition insufficient to guide practice, but most clinicians will encounter such cases at some point in their careers. By documenting the experiences and learning of clinicians who have worked with cases that are ‘out of the ordinary’, the book addresses an important gap in the literature. The book discusses 23 challenging and fascinating cases that fall outside what can be considered routine practice. Divided into three sections, the text begins by addressing rare and unusual conditions, defined as either conditions with a low incidence, or cases with an atypical presentation of a condition. It goes on to examine circumstances where an accurate diagnosis and/or coherent case formulation has been difficult to reach. The final section addresses controversial conditions in neuropsychology, including those where there is ongoing scientific debate, disagreement between important stakeholders, or an associated high-stakes decision. This text covers practice across lifespan and offers crucial information on specific conditions as well as implications for practice in rare disorders. This book will be beneficial for clinical neuropsychologists and applied psychologists working with people with complex neurological conditions, along with individuals from medical, nursing, allied health and social work backgrounds. It will further be of appeal to educators, researchers and students of these professions and disciplines.

Autistic Intelligence
Author: Douglas W. Maynard
Publisher: University of Chicago Press
ISBN: 0226816001
Category : Medical
Languages : en
Pages : 282
Book Description
Examines the diagnostic process to question how we understand autism as a category and to better recognize its intelligence and uncommon sense. As autism has become a widely prevalent diagnosis, we have grown increasingly desperate to understand it. Whether by placing baseless blame on vaccinations or seeking a genetic cause, Americans have struggled to understand what autism is and where it comes from. In Autistic Intelligence, Douglas Maynard and Jason Turowetz focus on a different origin of autism: the diagnostic process. By looking at how autism is diagnosed, they ask us to question the norms we use to measure autistic behavior against, why we understand autistic behavior as disordered, and how we go about assigning that disorder to particular people. To do so, the authors take a close look at a clinic in which children are assessed for and diagnosed with autism. Their research draws on hours observing assessment evaluations among psychologists, pediatricians, parents, and children in order to make plain the systems, language, and categories that clinicians rely upon when making their assessments. Those diagnostic tools determine the kind of information doctors can gather about children, and indeed, those assessments affect how children act. Autistic Intelligence shows that autism is not a stable category, but the result of an interpretive act, and in the process of diagnosing children with autism, we often miss all of the unique contributions they make to the world around them.

Diagnostic Issues in Substance Use Disorders
Author: John B. Saunders
Publisher: American Psychiatric Pub
ISBN: 1585626783
Category : Medical
Languages : en
Pages : 353
Book Description
Inviting the help of colleagues worldwide, the concise Diagnostic Issues in Substance Use Disorders is part of the new series Advancing the Research Agenda for DSM-V. Its 19 chapters by an international group of experts are designed to stimulate questions that will help guide research related to the development of the next editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) and the International Classification of Diseases (ICD-11), with the goal of ensuring that the major substance use diagnoses represent the same condition in both references. They cover 10 major issues in three main sections: Overarching issues relevant for the development of international diagnostic systems -- statistical modeling techniques and whether DSM-V should use categorical and/or dimensional diagnostic approaches; methods review, emphasizing new hybrid techniques for developing and testing diagnostic concepts; the need for separate clinical and research-oriented diagnostic criteria, incorporating both categorical and dimensional attributes; neurobiological changes characterizing substance dependence; the importance of cultural attributes in developing definitions of substance use disorders; and the history of the development of diagnostic systems and how to optimize the "crosswalk" between DSM and ICD. Research questions more specific to the substance use disorders section of DSM -- comorbidity between substance use disorders and other psychiatric conditions, the relatively unique clinical course of substance-induced mental disorders and appropriate treatment approaches; the precision of the criteria and threshold for a diagnosis and how to improve them; the subtypes of substance use disorder, including how they have been derived and the extent to which they relate to neurobiological processes; the seemingly high prevalence of alcohol dependence in young people; suggested research questions to evaluate the application of diagnostic criteria to adolescents; and the specific psychoactive substances cannabis and nicotine. Whether substance use disorders should be included in a broader section termed "addictive disorders" -- impulse-control disorders (especially pathological gambling and the advantages and disadvantages of adding it to the current substance use disorders section), identifying research opportunities regarding their assessment and neurocognitive and physiological bases, discussing the specifics of the research agenda and how it might be implemented, and presenting questions generated by the research agenda developmental process. This informative compendium distills the findings of a wealth of recent research and concludes with recommendations for exploiting research opportunities that promise to inform decisions regarding DSM-V and other classification systems. As such, it will prove invaluable for clinicians and researchers everywhere.
