The public depends on competent risk assessment from the federal government and the scientific community to grapple with the threat of pollution. When risk reports turn out to be overblownâ€"or when risks are overlookedâ€"public skepticism abounds. This comprehensive and readable book explores how the U.S. Environmental Protection Agency (EPA) can improve its risk assessment practices, with a focus on implementation of the 1990 Clean Air Act Amendments. With a wealth of detailed information, pertinent examples, and revealing analysis, the volume explores the "default option" and other basic concepts. It offers two views of EPA operations: The first examines how EPA currently assesses exposure to hazardous air pollutants, evaluates the toxicity of a substance, and characterizes the risk to the public. The second, more holistic, view explores how EPA can improve in several critical areas of risk assessment by focusing on cross-cutting themes and incorporating more scientific judgment. This comprehensive volume will be important to the EPA and other agencies, risk managers, environmental advocates, scientists, faculty, students, and concerned individuals.

Among the issues confronting America is long-term care for frail, older persons and others with chronic conditions and functional limitations that limit their ability to care for themselves. Improving the Quality of Long-Term Care takes a comprehensive look at the quality of care and quality of life in long-term care, including nursing homes, home health agencies, residential care facilities, family members and a variety of others. This book describes the current state of long-term care, identifying problem areas and offering recommendations for federal and state policymakers. Who uses long-term care? How have the characteristics of this population changed over time? What paths do people follow in long term care? The committee provides the latest information on these and other key questions. This book explores strengths and limitations of available data and research literature especially for settings other than nursing homes, on methods to measure, oversee, and improve the quality of long-term care. The committee makes recommendations on setting and enforcing standards of care, strengthening the caregiving workforce, reimbursement issues, and expanding the knowledge base to guide organizational and individual caregivers in improving the quality of care.
