Across healthcare settings, older adults represent the majority of consumers served. They present with the most clinically and socially complex situations and thus require nurses to possess highly developed assessment competencies, critical thinking abilities, and relationship-based skills. Nurses have an enormous responsibility when providing care to older adults in this rapidly changing healthcare environment with its increasing regulatory requirements, variable staffing levels, and unpredictable reimbursement. Nurses also have an amazing opportunity to positively change the daily experiences and health of older adults. As in the previous editions, authors present up-to-date information on assessment and interventions for common health problems and geriatric syndromes. They expanded their robust clinical content to include evidence based approaches to support LGBTQ elders, persons living with dementia and their families, and older adults living with HIV. In this sixth edition, the authors provide guidelines that are developed by experts on the topics of each chapter and are based on the best available evidence. A systematic method, the AGREE (Appraisal of Guidelines for Research and Evaluation) process, was used to evaluate the protocols and identify a process to help the reader to improve the validity of the book’s content.
