It meets the market need for a resource that concisely encapsulates current knowledge on the medical management of specific topics in a setting relevant to the preoperative clinic.  In so doing the book aims to improve patient care and safety, enhance resource use, facilitate appropriate and timely management of preexisting conditions and diminish patient concerns. Organized into sections according to body system, each section consists of chapters delineating a specific disorder. Each chapter starts with a clinical vignette followed by a question-and-answer style investigation of the relevant issues. These questions attempt to address commonly encountered clinical dilemmas where opinion often differs between, and occasionally within, medical sub-specialties. Expertly written chapters are also supplemented bya number of chapters which address special considerations such as the frail patient and chronic opioid use.
