This book provides primary care clinicians, researchers, and educators with a guide that helps facilitate comprehensive, evidenced-based healthcare of women and gender diverse populations. Many primary care training programs in the United States lack formalized training in women’s health, or if they do, the allotted time for teaching is sparse. This book addresses this learning gap with a solid framework for any program or individual interested in learning about or teaching women’s health. It can serve as a quick in-the-clinic reference between patients, or be used to steer curricular efforts in medical training programs, particularly tailored to internal medicine, family medicine, gynecology, nursing, and advanced practice provider programs. Organized to cover essential topics in women’s health and gender based care, this text is divided into eight sections: Foundations of Women's Health and Gender Based Medicine, Gynecologic Health and Disease, Breast Health and Disease, Common Medical Conditions, Chronic Pain Disorders, Mental Health and Trauma, Care of Selected Populations (care of female veterans and gender diverse patients), and Obstetric Medicine. Using the Maintenance of Certification (MOC) and American Board of Internal Medicine blueprints for examination development, authors provide evidence-based reviews with several challenge questions and annotated answers at the end of each chapter. The epidemiology, pathophysiology, evaluation, diagnosis, treatment, and prognosis of all disease processes are detailed in each chapter. Learning objectives, summary points, certain exam techniques, clinical pearls, diagrams, and images are added to enhance reader’s engagement and understanding of the material. Written by experts in the field, Sex and Gender-Based Women's Health is designed to guide all providers, regardless of training discipline or seniority, through comprehensive outpatient women’s health and gender diverse care.
