Illustrating the importance of asthma monitoring practices, this book covers how to assess disease levels in specific population groups; identifies social, geographical, and environmental factors that may influence the development of asthma; and discusses the design of cost-effective prevention and management strategies. The book reviews monitoring devices and their interpretation using established and innovative statistical techniques, methods of self-monitoring and monitoring using the Internet, monitoring strategies for the investigation of asthma triggers, and important findings gleaned from the post-marketing surveillance of asthma drugs and the monitoring of asthma mortality.
