“Since asthma surveillance data were not available at the census tract level for most of Louisiana, we estimated asthma burden using the inpatient discharge data available through LDH.”  (4)

“Case counts are not provided for CTs with a 2018 population of less than 800 to safeguard privacy.” (4)

“To minimize the need for suppression, inpatient discharge data was aggregated for the three most recent years available (2017–2019) and average annual crude rates were calculated for cases where asthma (ICD-10 code J45) was the primary diagnosis, as well as where asthma was any diagnosis.” (4)

“Spearman’s Rank Correlation was utilized to analyze the correlation between various social and environmental vulnerability factors, COVID-19 incidence, and the measures of asthma risk by CT.” (4)

“This was performed by first ranking the values in each dataset using RANK.AVG function in MS Excel 2016, followed by applying the PEARSON function to compare two datasets. Significance was set at alpha less than 0.05 (α < 0.05), with degrees of freedom (df) equal to two less than the total number of data points represented in both datasets” (4)

The research team works for the Section of Environmental Epidemiology and Toxicology, Office of Public Health, Louisiana Department of Health in Baton Rouge. Team members included Arundhati Bakshi; Shanon Soileau; Collete Stewart; Kate Friedman; Collete Maser; Alexis Williams; Kathleen Aubin; and Alicia Van Doren. 

“Currently, much of the environmental focus of the pandemic remains on PM2.5 levels; however, we noted that higher levels of ozone was consistently associated with higher incidence rates of COVID-19, and it was the only environmental factor that appeared to have an additive effect over SVI on COVID-19 incidence (Fig 1).” (11)

“Specifically, our data show a moderately strong positive correlation between SVI due to minority status/language barrier and three health data variables: asthma hospitalization; estimated asthma prevalence; and cumulative COVID-19 incidence at 3 months (Table 2). Interestingly, SVI measures were either negatively or not significantly correlated COVID-19 incidence at the 9-and 12-month time points, indicating that social vulnerability factors may have played a greater role in COVID-19 spread early in the pandemic, but may have been of diminishing importance as the pandemic wore on (Fig 1 and Table 2).” (9)

This document uses data resources from the Center for Disease Control/Agency for Toxic Substances and Disease Registry (CDC/ATSDR), the Environmental Protection Agency (EPA), and the Louisiana Department of Health (LDH).

These data resources include the Social Vulnerability Index (2018 - CDC/ATSDR), the NATA Respiratory Hazard Index (EPA 2014), PM2.5level (average annual concentration in ug/m3, EPA 2016), ozone level (summer seasonal average of daily maximum 8-hour concentration in air in parts per billion, EPA 2016), indoor mold concerns reported to IEQES program (average annual number of calls, LDH 2017-2019), cumulative COVID-19 incidence rate at 3-, 6-, 9- and 12-month increments (LDH March 2020 - March 2021), asthma hospitalization (average annual crude rate, where asthma was a primary diagnosis among hospitalization cases, LDH 2017-2019), and estimated asthma prevalence (average annual crude rate, where asthma was any diagnosis among hospitalization cases, LDH 2017-2019).

This registry allows for the tracking of the health effects of the 9/11 disaster. It is open to the public, where they can see the most common disorders and afflictions that those effected by 9/11 are dealing with today. The public can access this website and read up on the rates of lung infection, heart disease, PTSD, alcohol use, as well as the effect it has had on adolescent health. This registry was not only set up for the public use though, it is also used and produced by researchers. The researchers track the longterm health effects 9/11 has had on those exposed. The data also provides experts and researchers with the means to draw conclusions and analyses. Learning about the long term effects of 9/11 will raise awareness as well as allow for the understanding of how disasters of this caliber can effect those around it, in both long term and short term ways. 

Researchers use this system extensively in order to find correlations between 9/11 and different repercussions as well as to collect and gather data about those who were exposed during 9/11. A unique aspect of this registry is that it contains more participants than any other registry of its kind, making it a great tool for researchers. The public also utilizes this information to study their own forms of various research as well as to gain knowledge on possible afflictions related to the event. The registry also follows up with participants with interviews and matches with other health registries. The website also offers resources to researchers to learn more about the research at hand and where to find other published reports about 9/11.

The registry is funded with federal tax dollars. New York City itself has funded specific projects for the registry research, for example the respiratory study of Lower Manhattan. The registry is hosted by NYC Department of Health and Mental Hygiene but is mostly paid for by federal taxes. 

As mentioned, this site offers data on long term health afflictions of those exposed to 9/11. Yet the site also offers information about the participants in the registry. How they were selected, how many people are entered in the registry and where their exact locations were during the attacks. On top of providing data on the participants, the site also offers information on funding, as well as access to annual reports addressing the health impacts of 9/11. The site also gives access to those that the registry works with and collaborates with. The history behind the registry and the attacks are also provided. Sources for all data and a full bibliography is also available along with information about legal aspects of the health and compensation act, enrollee's confidentiality and thousands of other resources. 

The data is mainly visualized in report form. There is also a section of the site where data and statistics that have been confirmed are written out separated by disease/disorder type. So in the "what we know" tab PTSD, depression, tobacco use, asthma, lung function, respiratory issues, heart disease and adolescent health are separated into different sections with confirmed disease rates, correlations and numbers listed beneath each section. The same group that runs this registry in terms of research, called the 'WTC Medical Working Group' also provides links to other current studies on the matter, some of which they have partaken in. 

This site runs like any run of the mill website. If there are any issues or questions about the website there is contact information provided to seek assistance with the site or ask questions regarding the information.
