“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)

“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)

Xavier University of Louisiana -  Oschner and Xavier’s partnership has been centered around establishing a joint College of Medicine, to “create a strong physician pipeline that addresses longstanding inequities within the nation’s health care system and builds the health care workforce of the future” (Xavier University 2023). Xavier and Oschner have partnered since the early 1980s, when Oschner began offering clinical training sites for Xavier pharmacy students. Today, Ochsner and Xavier have established a master data sharing and use agreement that provides Xavier faculty with access to Oschner Health’s electronic medical record data. The program has hired four data scientists to provide data analytic services to Xavier faculty. They have also worked together to launch Oschner’s health equity data and quality improvement strategy. Advocacy emerging from this partnership has focused on the expansion of services covered by Medicaid to include tobacco cessation, as well as increasing access to evidence-based maternal health technology.

Chevron - Oschner’s partnership with Chevron is centered around a smoking cessation and education program that was launched in 2021. In 2023, Chevron opted to continue the partnership for a third consecutive year through a $50,000 donation. The program is offered in the following parishes: Jefferson, St. Tammany, East Baton Rouge, West Baton Rouge, Ascension, St. Charles, Terrebonne, and Lafourche.  In a press release for Oschner, cigarette smoking was described as “the leading cause of preventable deaths and diseases in the nation” (Oschner 2023). The release refers to America’s Health Rankings data that indicates smoking as one of the top 20 factors shaping poor health in Louisiana. This program is part of Oschner’s broader Healthy State initiative. Chevron funding also supports initiatives to encourage low-dose CT scans (to detect and diagnose lung cancer), teach high school students about the risks of smoking, and teach people to recognize and treat the stressors that lead to smoking.

 The Healthy State by 2030 initiative emerged in 2020. The goal of the initiative is to improve access to healthcare in Louisiana through community engagement and by partnering with organizations across different sectors (healthcare, business, religion, education, government, and education). The program also includes a focus on collecting, analyzing, and sharing health data. The program’s priorities are to reduce smoking cessation (with 214,000 fewer residents smoking by 2030); improve access to care for cancer and other chronic conditions like diabetes and high blood pressure through screenings (aiming for 100,000 fewer residents with chronic conditions by 2030); reduce obesity rates (with 182,000 “more physically active adults” by 2030); reduce rates of food insecurity (helping 72,000 more households gain access to healthy food); improve per-capita income levels (by $4,838); and improve access to high-speed internet (with 86,000 more homes having access). 

 This initiative is focused on improving health by improving “the conditions in which we are born, live, and work,” in the words of Dr. Eboni Price-Haywood, the medical director of the Healthy State 2030 Initiative and the Oschner Xavier Institute for Health Equity and Research. However, the projects that have been highlighted under this initiative seem to largely consist of expanding Oschners’ service delivery footprint. Ochsner’s expansion has been welcomed by communities that have long struggled to access care, but this form of intervention is limited in addressing broader structural drivers of health. 

One of the largest investments of Health States has revolved around the opening of five new health centers (in Baton Rouge, Lafayette, Monroe, and Shreveport). The health centers are framed as addressing health equity because they are “strategically located in areas of the state with high instances of chronic conditions, low birth weights, infant mortality, and early adult mortality” (Mcelfresh np, 2022). In addition to healthcare services, the centers offer resources for smoking cessation, diabetes management, and “social issues” that include transportation and food insecurity. Each center has an advisory council that includes patients, elected officials, businesspeople, and community members. 

In 2023, Oschner’s executive leadership announced their commitment to the Global Health Network (GHEN) Zero Health Gaps Pledge.  This initiative falls under the UN Sustainable Development Goals and has been described as a part of Healthy State.

Louisiana Clinical Data Research Network (LACDRN) is a collaborative project between the Louisiana Public Health Institute (LPHI), Pennington Biomedical Research Center, Tulane University, and Ochsner Health System. The network provides warehouses of clinical data available to clinical and health systems researchers: “representing a state and region that has unique health challenges related to disparities, natural disasters, high prevalence of chronic diseases, and some rare conditions, LACDRN is an important resource for clinical and health system research that will advance evidence-based diagnosis, treatment, disease management, and healthcare delivery” (Kurshid et al. 2014, 612).

Ochsner is using a digital platform developed by Unite US to expand and improve community health throughout Louisiana, in partnership with CVS Health and Humana. The platform is used by insurance companies’ care managers and provider teams to coordinate social services for patients. The Louisiana Unite US more than doubled following the outbreak of COVID-19 (Unite US, 2020).

As a tax-exempt hospital, Ochsner produces publicly accessible community health assessments as a requirement of the Patient Protection and Affordable Care Act (PPACA). As a statewide network, Ochsner has conducted health assessments for Shreveport, Lafayette, Monroe, New Orleans, Kenner, Baton Rouge, St. Mary, St. Anne, Northshore, Houma, Kaplan, Crowley, and Breaux Bridge, as well as Bay St. Louis in Mississippi. 

Ochsner’s proprietary Diversity, Equity and Inclusion (DE&I) Dashboard launched in 2022. The dashboard does not appear to be public however and there is very little available information about this tool. Ochsner's 2022-2023 impact report describes the tool as follows:  “In 2022, Ochsner’s proprietary Diversity, Equity and Inclusion (DE&I) Dashboard launched, informing delivery model innovations and enabling clinicians to identify populations with gaps in care and outcomes. The dashboard includes patient experience and care metrics, with data sortable by sociodemographic groups like race, location, and insurance type. Through the dashboard, we could see that 36% of Ochsner Health Network patients with hypertension are Black or African American, and of those, 80% have their hypertension controlled. In comparison, 86% of white patients with hypertension have it controlled. This data was in turn used to inform strategies to close gaps in care and improve outcomes”  (Ochsner 2022-2023 Impact Report, n.p.).

Ochsner’s  Enterprise Data Warehouse (EDW) stores clinical data collected over more than 20 years, includes data captured through EPIC/Clarity and claims data.

According to Philip M. Oravetz, MD, MPH, MBA, chief population health officer at Ochsner Health, Oschner is in the process of developing an electronic health record that includes demographic and SDOH data collected at the point of care, and then integrated into artificial intelligence (AI) and predictive modeling (Caffrey and Klein 2022).

Oschner was founded on January 2, 1942, in New Orleans by Alton Oschner, an American surgeon and medical researcher. Before founding Oschner, he worked at Tulane University and organized a surgical teaching program at New Orleans Charity Hospital. Oschner Medical Center, formerly known as the Oschner Clinic, was the first to document the connection between cancer and cigarette use. This work mobilized Oschner to expose the hazards of tobacco and pioneer the war against smoking.
