Preface to the Third Edition

Compiling and editing this third edition has been challenging because of the non-stop changes occurring in Medical Informatics in 2009. In some respects this has been a banner year because of new opportunities related to the American Recovery and Reinvestment Act. The stimulus package will undoubtedly impact multiple areas of health information technology, to include electronic health records, health information exchanges and informatics research.

We have made every attempt to provide the most up to date information about Medical Informatics issues by constantly reviewing the medical and lay literature. Our goal is to present the most recent changes, the most interesting concepts and both sides of each controversy. Our book is intended to be an introduction to the field of Medical Informatics that will entice individuals to go further in their education.

In our experience, individuals from all walks of life seem to be interested in this relatively new field. We hope our book will better educate technology workers about clinical issues and better educate clinical workers about technology issues.

Given the newness of this field, research may be lacking or inadequate in many areas of Medical Informatics. We have to rely on surveys and expert opinions in many areas. Frequently, this can result in more noise than signal and more hype than fact. We are dedicated to presenting the issues fairly and objectively. Approximately 1200 medical literature references and web links are included in this book that direct readers to more information.

While we are vendor-agnostic we are not opposed to presenting interesting hardware and software we think will be of interest to our readers. This will include all relevant open-source initiatives. One of the goals of this book is to promote and disseminate innovations that might help healthcare workers as well as technology developers. The fact we mention specific hardware or software or web-based applications does not mean we endorse the vendor; instead, it is our attempt to highlight an interesting concept that might lead others in a new direction.

In our 2009 book we have added new content to each chapter and added chapters on practice management systems and networks. Chapters on electronic health records and mobile technology have been completely redone, reflecting the rapid change in those areas. Also, the HITECH Act as part of the stimulus package is discussed in regards to its impact on Medical Informatics in the first chapter.

We hope that you will see interrelationships between the topics mentioned in multiple chapters in this book. Articles written on the use of technology to improve patient care often involve telemedicine, patient safety, patient informatics, disease management and evidence based medicine.

Our book's emphasis will always be on the medical issues that the average clinician or hospital faces, with solutions that are easy to understand. We won't be reluctant to present the obstacles new innovations face or negative publications written on the subject. If we can introduce you to a single new concept or tool that improves patient care or makes your day easier, we will consider our work successful.

We appreciate feedback regarding corrections or future additions. We welcome your input so we can continue to publish the most accurate and up-to-date information.

Please note that all proceeds will be donated to the University of West Florida Foundation for the advancement of Medical Informatics education.
