Healthcare is an information problem needing an information solution using modern information technology.  The traditional medical record does not suffice, but the new technologies of internet services do.  Existing technologies can be combined for new methods of gathering and analyzing health information, via monitors using sensors and clusters using supercomputers.  There is a way of utilizing both the electronic medical record of the past and the personalized genomic medicine of the future.  It gathers information from all the sources affecting personal health:  from the bodies of individuals to the societies of populations. Healthcare Infrastructure: Health Systems for Individuals and Populations describes the new healthcare infrastructure that will gather these personal health records from every individual and correlate each longitudinal record across whole populations.  This book explains the problems of personal medicine and public health, then the solutions possible with information technology.  Health determinants for individuals and populations are examined at length, along with present and future technologies to measure these.  Computer analysis will produce clusters of persons with similar measurements of health status.  The analysis discovers which persons have which outcomes and the management uses this knowledge to provide efficient healthcare. The new healthcare infrastructure will provide information for decision makers to effectively manage provider care and manage patient expectations.  Thus, this book will be a key reference for all professionals working within the management of health, from informatician to healthcare executive, health information technologist to computer scientist, and physician to patient.
