This book is the 3rd volume in the Resilient Health Care series. Resilient health care is a product of both the policy and managerial efforts to organize, fund and improve services, and the clinical care which is delivered directly to patients. This volume continues the lines of thought in the first two books. Where the first volume provided the rationale and basic concepts of RHC and the second teased out the everyday clinical activities which adjust and vary to create safe care, this book will look more closely at the connections between the sharp and blunt ends. Doing so will break new ground, since the systematic study in patient safety to date with few exceptions has been limited.
