This practical, unique textbook provides a foundation for the essential elements of patient safety and quality improvement (QI) for orthopaedic trainees, though the content covered will be of interest to veteran clinicians as well. Currently, there are few existing resources and didactics focused on this crucial yet often overlooked area of medical practice, which makes this the first true textbook on the subject within the field of orthopaedic surgery.   Utilizing a user-friendly approach including generous figures, tables, and bulleted key points, the text presents comprehensive background information on QI principles, models, and patient safety. More specifically, it focuses on orthopaedic concerns, such as biologics and implants, registries, checklists, surgical site infection risk reduction, use of evidence-based medicine and care maps, simulation to improve care, and shifting from volume to value, among others. Related topics such as diversityand inclusion, provider wellness strategies, leadership strategies to develop an efficient and safe work culture, and innovation are also presented. Throughout, the aim is to demonstrate that QI is a multidisciplinary goal that can only flourish in an environment of supportive accountability.  With contributions by leaders in the field, Quality Improvement and Patient Safety in Orthopaedic Surgery provides trainees and surgeons in the field a valuable and pragmatic toolkit for successful and sustainable clinical practice.
