We’ve not yet reviewed, but wanted to alert readers to the the following documents, available for review at the New York State Health Department’s website:
- Health Consultation – Health Statistics Review Follow-up (Public Comment Draft) – March 26, 2007 – NEW
- Information Sheet – Health Statistics Review Follow-up (Public Comment Draft) – March 26, 2007 – NEW
- Written Response Form – Health Statistics Review Follow-up (PDF, 11KB, 1pg.) – March 26, 2007 – NEW
From the Information Sheet:
What is a health statistics review?A health statistics review uses existing health data from data sources like birth certificates and health registries to determine whether health outcomes in a particular community are occurring at higher, lower, or about the same level compared to statewide or national levels after taking into account the age, race, and sex of individuals in the community. A health statistics review does not tell us why elevations or deficits in health outcomes exist and can not prove whether there is a cause and effect relationship between exposure to chemicals and health outcomes. While a health statistics review can take risk factors commonly found on health records into account, a health statistics review may not be able to take into account certain individual risk factors for health outcomes such as medical history, genetics and occupational exposures which may explain the elevations or deficits. Rather a health statistics review can generate hypotheses and may indicate whether a more rigorous study should be considered. This health statistics review follow-up is the second major report resulting from the step-wise approach to addressing health outcome concerns related to environmental contamination in Endicott, NY.
Why was a health statistics review conducted?A health statistics review was conducted because of concerns about possible exposures to chemicals known as volatile organic compounds (VOCs). Groundwater in the Endicott area is contaminated with VOCs from leaks and spills associated with local industry and commercial businesses. Trichloroethene (TCE) and tetrachloroethene (PCE) are two main VOCs of concern in the area. The VOCs moved from the contaminated groundwater into air spaces in the soil and then into indoor air through cracks in foundations in some buildings, a process known as soil vapor intrusion. Because of possible health concerns, the New York State Department of Health conducted the prior health statistics review and the health statistics review follow-up.
The follow-up health statistics review gathered additional detailed information to see if known risk factors may have played a role in the higher than expected levels of health outcomes shown in the previous review. The follow-up looked at individual birth defect records, birth certificates, cancer records, and death certificates to find information about risk factors such as smoking, occupational history, family medical history, and medication use. Newspaper obituaries, Motor Vehicle records, city directories, and telephone directories were used to trace residential histories.
The follow-up also reviewed two additional birth outcomes, conotruncal heart defects (specific defects of the heart’s outflow region) and stillbirths. The scientific literature suggests that both of these outcomes may be associated with TCE exposures. The follow-up also reviewed cancer incidence for all types of cancer, taking account of race. Findings from the follow-up review as well as the findings from the prior review were used to guide the development of possible options for next steps.
