This idea-packed resource takes systems and complexity sciences out of blue-sky territory and into the concrete world of contemporary healthcare practice. Beginning with a new reframing of health and illness, its chapters redesign traditional disease-centered models of care into modern, health-centeredand patient-centeredhealth service systems. The approaches shown here combine innovation and common sense to recognize and attend to patientsO needs across areas including health education and training, information accessibility, health service organization and delivery, and disease in individual context. The variety of solutions applied to this wide spectrum of issues shows the suitability of systems, complexity, and adaptive thinking to the ongoing objectives of making health services more responsive, effective, and equitable.
