Current electronic healthcare record (EHR) systems utterly fail to assist doctors and nurses in their work; designed without recognizing the actual needs of those users, but rather solving mostly administrative problems instead. This failure results in an ongoing lack of safety and efficiency in care delivery. We need to do much better. This book lays out how an effective EHR system should be built to deliver effective support for a doctor throughout the phases of her profession, from how a doctor learns her profession, to how she examines a patient, analyzes clinical findings, reaches conclusions, and finally applies therapy. The result is accurate, economic, safe, and consistent healthcare.
