vPreface to the Sixth EditionHealth Informatics is an information science thatis concerned with the management of healthcaredata and information using a variety oftechnologies. As a result of exploding technologiesand expansive healthcare data, in addition tosupport from US Federal Government programs,there is tremendous interest in this relatively newfield.In order to keep up with the rapid pace ofdevelopments in Health Informatics, this is oursixth edition since publishing the originaltextbook in 2007.The sixth edition has been endorsed by the AMIAfor continuing education of informaticists. Manyof our textbook authors are AMIA members andmajor contributors to the field of HealthInformatics.In this edition we have re-written all chapters toreflect the rapid changes in the field. We havefocused heavily on Meaningful Use, the yard stickfor electronic health record implementation in theUnited States.We added a new chapter on Healthcare DataAnalytics, given the interest in managinghealthcare data, to include “big data.” Weconsolidated the chapter on electronic prescribingand practice management systems into thechapter on electronic health records. The PACSchapter was changed to Medical ImagingInformatics and we added an academic radiologistas co-author.Readers can expect similar organization to eachchapter. All chapters start with learning objectivesand an introduction and end with recommendedreading, key points, future trends and aconclusion. In addition, most chapters includecase studies to highlight interesting national andinternational initiatives. We have made everyattempt to provide the most up-to-dateinformation about health informatics recentinformation and the most interesting concepts.We are dedicated to presenting the issues fairlyand objectively and have avoided the hype sometimes associated with new technologies. Thistextbook should give readers, especially those newtohealthcareortechnology,abetterunderstanding of this burgeoning field. It is also aresource/reference for people in the field,reviewing for clinical informatics board and forboth graduate and undergraduate courses.Approximately 1900 medical literature referencesand web links are included in this book that helpdirect readers to additional information.While we are vendor agnostic we are not opposedto presenting interesting hardware and software,including open source, we think will be of interestto our readers. One of the goals of this book is topromote and disseminate innovations that mighthelp healthcare workers as well as technologydevelopers. The fact that we mention specifichardware or software or web-based applicationsdoes not mean we endorse the vendor; instead, itis our attempt to highlight an interesting conceptor innovation that might lead others in a newdirection.A Resource Center was created for each bookchapter that contains articles, web links andvideos for students and instructors located atwww.informaticseducation.org .We appreciate feedback regarding how to makethis book as user friendly, accurate, up-to-dateand educational as possible. Please note that bookproceeds will be donated to support theadvancement of health informatics education.Robert E. Hoyt MD FACPAnn K. Yoshihashi MD FACEAcknowledgements: We would like to acknowledge Alison Fields for her invaluable support inperforming literature searches and proofreading that were critical in updating the sixth edition. Secondwe are indebted to Jo Ann Clay for transforming the format of the book and contributing to the overalllook and feel of the textbook.
