Complement in Health and Disease


Book Description

Since the first edition of Complement in Health and Disease was published in 1986, significant advances have been made. The cDNAs for all of the components and some of the receptors have been cloned and sequenced. The chromosomal localization and the structural organization of a number of these genes have now been determined. These advances are now facilitating research into the structure of the complement proteins, the nature of the complement deficiency syndromes, the regulation of complement gene expression and the role of complement in different diseases. This edition contains contributions from both basic and clinical scientists in a format which we hope will appeal to both immunologists and physicians who wish to know more about this fascinating and important host defence system. The introductory chapter by John Weiler presents a historical background to research on the complement system and describes the biochemical events occurring during activation of the system. In Chapter 2 Alastair Dodds and Tony Day discuss the phylogeny and evolution of the complement system. The techniques of protein chemistry and molecular biology have provided powerful insights into the modular structure of complement proteins and the evolution of the complement system. The structure and organisation of the complement genes is described in Chapter 3 by Ken Reid and Duncan Campbell. This chapter describes the modular structure of the complement proteins and some of the mutations which are responsible for deficiencies of individual components.










ICD-10-CM Official Guidelines for Coding and Reporting - FY 2021 (October 1, 2020 - September 30, 2021)


Book Description

These guidelines have been approved by the four organizations that make up the Cooperating Parties for the ICD-10-CM: the American Hospital Association (AHA), the American Health Information Management Association (AHIMA), CMS, and NCHS. These guidelines are a set of rules that have been developed to accompany and complement the official conventions and instructions provided within the ICD-10-CM itself. The instructions and conventions of the classification take precedence over guidelines. These guidelines are based on the coding and sequencing instructions in the Tabular List and Alphabetic Index of ICD-10-CM, but provide additional instruction. Adherence to these guidelines when assigning ICD-10-CM diagnosis codes is required under the Health Insurance Portability and Accountability Act (HIPAA). The diagnosis codes (Tabular List and Alphabetic Index) have been adopted under HIPAA for all healthcare settings. A joint effort between the healthcare provider and the coder is essential to achieve complete and accurate documentation, code assignment, and reporting of diagnoses and procedures. These guidelines have been developed to assist both the healthcare provider and the coder in identifying those diagnoses that are to be reported. The importance of consistent, complete documentation in the medical record cannot be overemphasized. Without such documentation accurate coding cannot be achieved. The entire record should be reviewed to determine the specific reason for the encounter and the conditions treated.

Improving Diagnosis in Health Care


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.




Complementary and Alternative Medicine in the United States


Book Description

Integration of complementary and alternative medicine therapies (CAM) with conventional medicine is occurring in hospitals and physicians offices, health maintenance organizations (HMOs) are covering CAM therapies, insurance coverage for CAM is increasing, and integrative medicine centers and clinics are being established, many with close ties to medical schools and teaching hospitals. In determining what care to provide, the goal should be comprehensive care that uses the best scientific evidence available regarding benefits and harm, encourages a focus on healing, recognizes the importance of compassion and caring, emphasizes the centrality of relationship-based care, encourages patients to share in decision making about therapeutic options, and promotes choices in care that can include complementary therapies where appropriate. Numerous approaches to delivering integrative medicine have evolved. Complementary and Alternative Medicine in the United States identifies an urgent need for health systems research that focuses on identifying the elements of these models, the outcomes of care delivered in these models, and whether these models are cost-effective when compared to conventional practice settings. It outlines areas of research in convention and CAM therapies, ways of integrating these therapies, development of curriculum that provides further education to health professionals, and an amendment of the Dietary Supplement Health and Education Act to improve quality, accurate labeling, research into use of supplements, incentives for privately funded research into their efficacy, and consumer protection against all potential hazards.




Determining Health Expectancies


Book Description

Health expectancies were developed to address the important question of whether or not we are exchanging longer life for poorer health - replacing quality by quantity. Health expectancies extend the concept of life expectancy to morbidity and disability by providing a means of dividing life expectancy into life spent in various states of good and bad health. Being independent of the size of populations and of their age structure, health expectancies thus allow direct comparison of the different groups that constitute populations: sexes, socio-professional categories, regions. This book brings together for the first time, the major works of REVES* over the past ten years. As well as providing comparisons of the health of many of the world's countries, the book includes sections on the concepts behind health expectancies and the demographic transition, the relevance of health expectancies to health policy and the different methods of calculating health expectancies. *REVES is an international organisation of researchers, clinicians and health planners addressing these issues as well as developing and recommending methods of calculation and furthering the use of health expectancy as a tool for health planning. * State-of-the-art coverage of this important health indicator * Heavily cross referenced to give the book structure and coherence * Editors are pioneers in the field of health expectancy

Beyond the HIPAA Privacy Rule


Book Description

In the realm of health care, privacy protections are needed to preserve patients' dignity and prevent possible harms. Ten years ago, to address these concerns as well as set guidelines for ethical health research, Congress called for a set of federal standards now known as the HIPAA Privacy Rule. In its 2009 report, Beyond the HIPAA Privacy Rule: Enhancing Privacy, Improving Health Through Research, the Institute of Medicine's Committee on Health Research and the Privacy of Health Information concludes that the HIPAA Privacy Rule does not protect privacy as well as it should, and that it impedes important health research.
