Chapter 5 SMART: Mobile Patient Monitoring in an Emergency Department Esteban Pino Universidad de Concepción, Concepción, Chile Dorothy Curtis Massachusetts Institute of Technology, USA Thomas Stair Harvard Medical School, Boston, USA Lucila Ohno-Machado University of California San Diego, USA INTRODUCTION As technology advances, there are more options available for pervasive monitoring. Sensor minia- turization, wireless communication and increasing processing power in smaller packages allow more efficient, reliable and convenient systems, at least from the end-user perspective. In healthcare, one of the main driving forces behind ubiquitous com- puting is the increasing need to move patient care from the hospital to non-standard settings such as homes, nursing homes, improvised waiting areas, hazardous locations or the battlefield. For at-risk ABSTRACT Patient monitoring is important in many contexts: at mass-casualty disaster sites, in improvised emergency wards, and in emergency room waiting areas. Given the positive history of use of monitoring systems in the hospital during surgery, in the recovery room, or in an intensive care unit, the authors sought to use recent technological advances to enable patient monitoring in more diverse circumstances: at home, while traveling, and in some less well-monitored areas of a hospital. This chapter presents the authors’ experiences in designing, implementing and deploying a wireless disaster management system proto- type in a real hospital environment. In addition to a review of related systems, the sensors, algorithms and infrastructure used in our implementation are presented. Finally, general guidelines for ubiquitous methodologies and tools are shared based on the lessons learned from the actual implementation. DOI: 10.4018/978-1-61520-765-7.ch004
