There are few resources and books for professionals within the patient safety sector that use case studies to model the practical application of theories of patient safety incident investigation. Exploring these theories, this text brings together contributors from a variety of academic and healthcare professions, alongside those with lived experience, to help you understand some of the emerging theories of safety science and their practical application. The NHS's approach to incident reporting in investigations, the Patient Safety Incident Response Framework (PSIRF), has given rise to new-found opportunities and freedom of investigation and incident management. This book aims to explore emerging safety sciences by leading experts and the practical application of them in differing clinical and organisational contexts.  Written by people who work in patient safety, and with chapters on subjects such as System Engineering Initiative for Patient Safety (SEIPS), AcciMaps and Human Factors, this book is for everyone with an interest in how the landscape of patient safety is changing and how to apply good practice for the reduction of avoidable harm.
