Calculating census tract-based life expectancy in New York state: a generalizable approach.

Background: Life expectancy at birth (LE) has been calculated for states and counties. LE estimates at these levels mask health disparities in local communities. There are no nationwide estimates at the sub-county level.

Total trihalomethanes in public drinking water supply and birth outcomes: a cross-sectional study.

Reproductive effects of long-term, low-dose exposure to disinfectant by-products have not been consistently documented in large populations despite the known toxicity of high exposures and the wide-spread occurrence of low concentrations in public drinking water. We investigated the effect of low-dose exposure to total trihalomethanes (TTHM) on birth weight and gestational term in New York State. All singleton live births from 1998 through 2003 in 62 counties in New York State were linked with public water supply (PWS) system boundaries based on mother's residential address on birth certificate.

Hospital emergency department visits for carbon monoxide poisoning following an October 2006 snowstorm in western New York.

Following an October 2006 snowstorm that caused widespread power outages in western New York State, hospital emergency department (ED) visits for carbon monoxide (CO) poisoning increased. Overall, 264 people representing 155 households were diagnosed with CO poisoning during the power outages. Telephone interviews were conducted with a subset of these individuals.

Development of an interactive environmental public health tracking system for data analysis, visualization, and reporting.

Healthcare providers and governmental agencies routinely collect and report data on health outcomes. In addition, governmental agencies and industry collect and report information on environmental hazards and exposures that may impact health. Use of these data for environmental public health tracking has been a challenge because these data are managed by different data stewards, may contain confidential information that must be protected, and have not been collected in a manner to facilitate linkages.

Development of a web-based integrated birth defects surveillance system in New York State.

Background: Over the past decade, the Internet has become a powerful and effective tool for public health surveillance. The objectives of this project were to develop secure Web-based applications for Birth Defects Surveillance and to integrate them into routine surveillance activities of the New York State (NYS) Congenital Malformations Registry (CMR).

Methods: The Web-based applications were developed on infrastructure of New York State Health Provider Network using JAVA programming language.

Use of CUSUM and Shewhart charts to monitor regional trends of birth defect reports in New York State.

Background: Cumulative sum (CUSUM) charts were originally developed for industrial quality control, but may be adapted for the surveillance of health outcome data, such as birth defects. The reported prevalence of birth defects can vary due to differences in case ascertainment, surveillance practices, or true changes in prevalence. We examined the utility of CUSUM and Shewhart charts for detect-ing changes in prevalence of two different birth defect groups.
