The Utility of Virtual Home Visits to Reduce Asthma Burden in Low-Income Black Communities in Louisiana During the COVID-19 Pandemic.

OBJECTIVES: The Louisiana Department of Health identified a need for greater outreach in low-income Black communities that addressed environmental asthma triggers. We piloted an asthma virtual home visit (VHV) program and evaluated its reach and ability to promote asthma self-management strategies in communities with a high prevalence of poorly controlled asthma. METHODS: Participants from Louisiana were continuously recruited into the VHV program starting in March 2021 and provided with asthma education materials. Participants reporting poorly controlled asthma and environmental triggers were also offered 3 VHVs with a respiratory therapist. All participants were asked to complete a preintervention and postintervention knowledge test, an Asthma Control Test (ACT) (maximum score = 25; scores ≤19 indicate poorly controlled asthma), and a final survey that assessed perceptions about asthma management and reduction of environmental triggers. RESULTS: As of October 2022, 147 participants were enrolled in the program, and 52 had consented to and received ≥1 VHV. Forty VHV recipients (77%) were aged <18 years, 40 (77%) were Black people, and 46 (88%) were from families with extremely low or low incomes. Asthma symptoms improved across all participants, with a median increase of 2.4 points on the ACT. Knowledge tests revealed that 86% of participants learned about ≥1 new asthma trigger; a larger percentage of VHV recipients than nonrecipients (68% vs 36%) had an improved knowledge test score postintervention. Compared with preintervention, about three-quarters of participants reported feeling more empowered to self-manage their asthma and a significant improvement in their quality of life postintervention. CONCLUSIONS: The program provided virtual asthma education to communities with a high burden of asthma and improved asthma outcomes for participants. Similar virtual models can be used to promote health equity, especially in areas with limited access to health care.

Identifying Louisiana communities at the crossroads of environmental and social vulnerability, COVID-19, and asthma.

The COVID-19 pandemic has disproportionately affected the socially and environmentally vulnerable, including through indirect effects on other health conditions. Asthma is one such condition, which may be exacerbated by both prolonged adverse in-home exposures if quarantining in unhealthy homes and prolonged outdoor exposures if the ambient air quality is unhealthy or hazardous. As both are often the case in Environmental Justice (EJ) communities, here we have analyzed data at the census tract (CT) level for Louisiana to assess any correlation between social and environmental vulnerability, and health issues like COVID-19 and asthma. Higher Social Vulnerability Index (SVI), Particulate Matter less than 2.5 µm in diameter (PM2.5) and Ozone levels were associated with higher rates of cumulative COVID-19 incidence at various time points during the pandemic, as well as higher average annual asthma hospitalization rates and estimated asthma prevalence. Further, cumulative COVID-19 incidence during the first three months of the pandemic was moderately correlated with both asthma hospitalizations and estimated prevalence, suggesting similar underlying factors may be affecting both conditions. Additionally, 137 CTs were identified where social and environmental vulnerabilities co-existed, of which 75 (55%) had high estimated prevalence of asthma. These areas are likely to benefit from asthma outreach that considers both social and environmental risk factors. Fifteen out of the 137 CTs (11%) not only had higher estimated prevalence of asthma but also a high burden of COVID-19. Further research in these areas may help to elucidate any common social determinants of health that underlie both asthma and COVID-19 burdens, as well as better clarify the possible role of the environment as related to the COVID-19 burden in Louisiana.

Acute Illnesses and Injuries Related to Total Release Foggers - 10 States, 2007-2015.

Total release foggers (TRFs) (also known as "bug bombs") are pesticide products often used indoors to kill insects. After an earlier report found that TRFs pose a risk for acute illness (1), the Environmental Protection Agency required improved labels on TRFs manufactured after September 2012 (2). To examine the early impact of relabeling, the magnitude and characteristics of acute TRF-related illness were evaluated for the period 2007-2015. A total of 3,222 TRF-related illnesses were identified in 10 participating states, based on three data sources: Sentinel Event Notification System for Occupational Risk-Pesticides (SENSOR) programs, the California Department of Pesticide Regulation (CDPR) program, and poison control centers (PCCs) in Florida, Texas, and Washington. No statistically significant decline in the overall TRF-illness incidence rate was found. Failure to vacate treated premises during application was the most commonly reported cause of exposure. To reduce TRF-related illness, integrated pest management strategies (3) need to be adopted, as well as better communication about the hazards and proper uses of TRFs. Redesigning TRFs to prevent sudden, unexpected activation might also be useful.
