The Future of the Public’s Health in the 21st Century
census tracts, and the rapid identification of an unusual cluster of events. The value of this type of real-time monitoring of unusual disease outbreaks is obvious for early identification of bioterrorism attacks as well as for improvements in clinical care and population health.
Reports of sentinel events have proved useful for the monitoring of many diseases, but such reports may be serendipitous and generated because of close clustering, unusual morbidity and mortality, novel clinical features, or the chance availability of medical expertise. Sentinel networks that specifically link groups of participating health care providers or health care delivery systems to a central data-receiving and -processing center have been particularly helpful in monitoring specific infections or designated classes of infections. Examples of such networks are the National Nosocomial Infections Surveillance system and the National Molecular Subtyping Network for Foodborne Disease Surveillance (PulseNet). More recently, CDC has implemented a strategy directed to the identification of emerging infectious diseases in collaboration with many public health partners. The Emerging Infections Program (EIP) is a collaboration among CDC, state public health departments, and other public health partners for the purpose of conducting population-based surveillance and research on infectious diseases. At present, nine states (California, Colorado, Connecticut, Georgia, Maryland, Minnesota, New York, Oregon, and Tennessee) act as a national resource for the surveillance, prevention, and control of emerging infectious diseases (CDC, 2002). The EIP sites have performed investigations of meningococcal and streptococcal diseases and have established surveillance for unexplained deaths and severe illnesses as an attempt to identify diseases and infectious agents, known and unknown, that can lead to severe illness or death (CDC, 2002).
Preparing Health Care Professionals
Academic health centers (AHCs) serve as a critical interface with governmental public health agencies in several ways. First, as noted earlier, AHCs are an important part of the safety-net system in most urban areas. Second, they are the principal providers of specialized services and serve as regional referral centers for smaller towns or cities and rural areas. Both in normal periods and especially when confronted with either natural disasters or terrorist events, the specialized care units are an essential resource for public health. Moreover, they are also primary loci for research and training. AHCs also have a unique and special set of values that they bring to health care that transcend the discrete functions they perform.
