An informatics agenda for public health: summarized recommendations from the 2011 AMIA PHI Conference.

The AMIA Public Health Informatics 2011 Conference brought together members of the public health and health informatics communities to revisit the national agenda developed at the AMIA Spring Congress in 2001, assess the progress that has been made in the past decade, and develop recommendations to further guide the field. Participants met in five discussion tracks: technical framework; research and evaluation; ethics; education, professional training, and workforce development; and sustainability. Participants identified 62 recommendations, which clustered into three key themes related to the need to (1) enhance communication and information sharing within the public health informatics community, (2) improve the consistency of public health informatics through common public health terminologies, rigorous evaluation methodologies, and competency-based training, and (3) promote effective coordination and leadership that will champion and drive the field forward. The agenda and recommendations from the meeting will be disseminated and discussed throughout the public health and informatics communities. Both communities stand to gain much by working together to use these recommendations to further advance the application of information technology to improve health.

An integrated information system for all-hazards health preparedness and response: New York State Health Emergency Response Data System.

Effective and timely exchange of information among healthcare, state and local public health, and other health emergency response partners is essential to all-hazards emergency preparedness and response. Since fall of 2001, NY State Department of Health has partnered with the healthcare and public health community in New York to implement a statewide Health Emergency Response Data System to meet this need. During this time, it has been used in a wide range of preparedness and response applications including regional and local exercises, surveillance, health facility asset tracking, and response to actual health events. The architecture, design, and implementation model used in the system readily support all-hazards preparedness and response at state, regional, and local levels. It has become one of the most important assets to health emergency response in New York State.

Dead crow density and West Nile virus monitoring, New York.

New York State used the health commerce system to monitor the number of West Nile virus (WNV) human disease cases and the density of dead crows. In each year from 2001 to 2003 and for the 3 years combined, persons living in New York counties (excluding New York City) with elevated weekly dead crow densities (above a threshold value of 0.1 dead crows per square mile) had higher risk (2.0-8.6 times) for disease caused by WNV within the next 2 weeks than residents of counties reporting fewer dead crows per square mile. This type of index can offer a real-time, relatively inexpensive window into viral activity in time for prevention and control. Changes in reporting, bird populations, and immunity may require that thresholds other than 0.1 be used in later years or in other areas.
