Perspective of an emergency physician group as a data provider for syndromic surveillance

The need for enhanced biologic surveillance has led to the search for new sources of data. Beginning in September 2001, Emergency Medical Associates (EMA) of New Jersey, an emergency physician group practice, undertook a series of surveillance projects in collaboration with state and federal agencies. This paper examines EMA's motivations and concerns and discusses the collaborative opportunities available to data suppliers for syndromic surveillance. Motivations for supplying data included altruism and public service, previous involvement in terrorism and disaster preparedness, academic research interests, and the opportunity to find added value in the group's existing information systems. Concerns and barriers included cost, maintaining patient confidentiality, and challenges in interacting with the public health community. The extensive and carefully maintained electronic medical record enabled EMA to conduct multiple studies in collaboration with state and federal agencies. The electronic medical record provides useful data that might be more sensitive and specific in detecting outbreaks than the patient-chief-complaint data more commonly used for surveillance. EMA's experience also indicates that opportunities exist for the public health community to work with emergency physicians and emergency physician groups as suppliers of data. Such collaborations not only are useful for syndromic surveillance systems but also can help build relations that might facilitate a response to an actual biologic attack.
