Book excerpt: The Handbook of Health Social Work provides a comprehensive and evidence-based overview of contemporary social work practice in health care. Written from a wellness perspective, the chapters cover the spectrum of health social work settings with contributions from a wide range of experts. The resulting resource offers both a foundation for social work practice in health care and a guide for strategy, policy, and program development in proactive and actionable terms.

Health Social Work Practice: A Spectrum of Critical Considerations delves into critical practice issues such as theories of health behavior; assessment; effective communication with both clients and other members of health care teams; intersections between health and mental health; the effects of religion and spirituality on health care; family and health; sexuality in health care; and substance abuse. Health Social Work: Selected Areas of Practice presents a range of examples of social work practice, including settings that involve older adults; nephrology; oncology; chronic diseases such as diabetes, heart disease, and HIV/AIDS; genetics; end of life care; pain management and palliative care; and alternative treatments and traditional healers. The first book of its kind to unite the entire body of health social work knowledge, the Handbook of Health Social Work is a must-read for social work educators, administrators, students, and practitioners.
