This book serves as the pillar for clinical care teams to improve health equity among homeless older adults. Interdisciplinary care teams are essential in complex homeless older population clinical practice, as all disciplines must work together to address medical, surgical, behavioral, nutritional, and social determinants of health. All clinicians who treat older adults, from the independent to the frail, should approach problem solving via an inclusive approach that includes social work, pharmacy, nursing, rehabilitation, administrative, and medicine inputs. The social determinants of health that contribute to the complexities of clinical care outcomes cannot be addressed within silos. The book reflects a holistic care model to assist clinicians in the complicated homeless population that is continuing to change in the instability of the homeless environment.
