Book excerpt: Properly performing health care systems require concepts and methods that match their complexity. Resilience engineering provides that capability. It focuses on a system’s overall ability to sustain required operations under both expected and unexpected conditions rather than on individual features or qualities. This book contains contributions from international experts in health care, organisational studies and patient safety, as well as resilience engineering. Whereas current safety approaches primarily aim to reduce the number of things that go wrong, Resilient Health Care aims to increase the number of things that go right.
