This book describes real-world examples and practical approaches for integrating behavioral and physical health services in primary care and some specialty medical environments. Integrated care models are patient-centered; delivered by teams of medical professionals, utilize care coordination, and a population-based approach. This book is comfortably accessible to students, residents, faculty, and all mental health professionals, primary care and medical specialists who are working in ambulatory/office-based practices. We examine the integrated care literature and recommend applying collaborative care and other existing models of integrated care based on the existing evidence-based research. When there is no literature supporting a specific approach, our experts offer their ideas and take an aspirational approach about how to manage and treat specific behavioral disorder or problems. We assume the use of a fully integrated team staffing model while also recognizing this an ideal that may need modification based on local resources and practice cultures. The full integrated team includes a primary care or specialist provider(s), front desk staff, medical assistant(s), nurse(s), nurse practitioners, behavioral health specialist(s), health coaches, consulting psychiatrist, and care coordinator(s)/manager(s). The book has four sections: Part 1: Models of Integrated Care provides an overview of the principles and the framework of integrated care focusing on five highly successful integrated practices. We also discuss team-based care, financing, tele-behavioral health, and use of mental health assessments and outcome measures. Part 2: Integrative Care for Psychiatry and Primary Care is a review of existing and proposed models of integrated care for common psychiatric disorders. Our continuity approach emphasizes problem identification, differential diagnosis, brief treatment, and yearlong critical pathways with tables and figures detailing “how to” effectively deliver mental health care and manage substance misuse in an integrated care environment. Part 3: Integrated Care for Medical Sub-Specialties & Behavioral Medicine Conditions in Primary Care focuses on two models of integrating behavioral health care: (1) integrating wellness with behavioral health and (2) integrating psychiatry and neurology. Other chapters are “Women’s Mental Health Across the Reproductive Lifespan,” “Assessing and Treating Sexual Problems in an Integrated Care Environment,” “Integrated Chronic Pain and Psychiatric Management,” and “Death and Dying: Integrated Teams.” Part 4: Psychosocial Treatments in Integrated Care describes brief office-based counseling and psychosocial treatment approaches including: health coaching, crisis intervention, family, and group interventions. All of these brief treatment approaches are patient–centered, tailored to be used effectively integrated care settings and as an important contribution to population management.
