Book excerpt: Health systems worldwide are grappling with the challenge of coordinating difference in an increasingly complex care environment. In response this book features the latest research on organizational studies in healthcare and explores the relationship between strategic and organic change and what this means for the way we organize health work. Focusing on the complexity of healthcare environments, it discusses the need to cross professional and organizational boundaries. Specifically, this book focuses on the implications for health systems in the way that they continue to balance planning and intervention with organic learning systems. Comprising the best contributions from the 2018 Conference on Organizational Behaviour in Health Care (OBHC), this book is an important resource for healthcare researchers, as well as policy-makers and managers within the industry. Contributors explore the extent to which healthcare is codified through empirical analysis of practical interventions and conceptual debate.
