Book excerpt: Distilling the ideas central to managing operating theatres, this book provides a practical and easy to use toolkit to improve theatre efficiency and patient outcomes. It advocates using time as the key measurement and proposes a new norm of operating theatre management based on rational, data-driven principles. Notions of 'efficiency' and 'scheduling' are clearly defined, and a scheduling toolkit available to download accompanies the work. The book's easy to use format supports managers in list planning, performance monitoring and demand-capacity matching while considering limited budgets and resources. It includes contributions from around the world, demonstrating the global application of its core approach. Aimed primarily at operating theatre managers, this book will also interest consultants, senior trainees, nurses and administrators who are involved in the daily running of the operating theatre and/or want to develop their leadership/managerial skills.
