Close collaboration across agencies and international borders is mandatory for public health officials. A powerful tool for sharing knowledge, knowledge management (KM) can help public health professionals quickly collaborate and disseminate knowledge for solving public health issues worldwide. The latest initiatives for reforming healthcare have put the spotlight on the need for maximizing resources. In addition to providing a platform for sharing knowledge, KM can help healthcare professionals do more with less. One tool, two problems solved. Yet the sharing of knowledge and KM continues to be a major challenge in the public health field. Knowledge Management in Public Health provides a general introduction to KM and social networking in the public health arena. The book begins with coverage of basic principles, components, and methodologies as well as trends and key issues in public health. It includes ten case studies illustrating applications of KM and social networking in public health. The chapters are written by leading individuals from organizations involved in applying KM in public health worldwide. The editors and chapter authors explore the many elements of KM, delineating how and why to start such an initiative. They provide specific examples of the development and value-added benefits of KM in a variety of public health environments. Tough or quick decision making has always benefitted enormously from knowledge based on the maximum amount of pertinent information available at the time--this has not changed. What is new in the present public health environment is the need to do this more often, with fewer personnel available, and increased expectations relative to the services expected by the public. Better use of information under a KM system is well suited to serve that purpose. This book explores the many ways to use KM to anticipate potential health issues and quickly resolve key incidents when they occur.
