ABSTRACT
Rationale: To reduce transmission of SARS-CoV-2, non-pharmaceutical interventions (NPIs), including school closures, hand hygiene, mask mandates, and social distancing, were enforced in Arkansas from 3/2020-2/2021. We hypothesized that the presence of NPIs would correlate with a decrease in asthma exacerbations and viral infections. Methods: Demographic information was collected on subjects with asthma exacerbations or viral infections from 3/2018-5/2022, including age, race, ethnicity, and sex. To evaluate the effects of NPIs, three periods were considered: pre- (03/2018-02/2020), during (03/2020-02/2021), and post- (03/2021-05/2022) NPIs. ANOVA analysis and generalized linear models were performed to determine statistical significance. The stringency of NPIs was evaluated using publicly available data (Oxford Covid-19 Government Response Tracker), which allows for direct comparison of Arkansas NPI status to exacerbation data during the same time periods. Results: 5055 asthma exacerbations (3322 unique subjects) occurred between 3/2018-5/2022. Asthma exacerbations decreased from 3/2020-3/2021 and returned to pre-pandemic numbers by summer 2021 (p<0.0001). Similar downward trends occurred for respiratory syncytial virus (RSV) with out-of-season return in summer 2021 (p<0.0001). Rhinovirus was present throughout NPIs. The mean age of exacerbations decreased by 0.9 years when comparing the during NPIs and after NPIs periods (p = 0.0002). An increase in the proportion of exacerbations was noted for non-black and other/unknown ethnicity subjects during and after NPIs. Conclusions: Fewer asthma exacerbations occurred during the most significant NPI employment period (03/2020-02/2021), and an increase in exacerbations was seen as mitigation strategies were relaxed, which correlated with timing of increasing RSV infections.
ABSTRACT
Rationale: Identification and control of environmental triggers is one of the cornerstones of asthma management. Access to homes, underscored during the COVID-19 pandemic, frequently limits mitigation efforts. We sought to determine the feasibility of telemedicine for identification of home asthma triggers. Methods: Patients age 5-18 years with persistent asthma, recent exacerbation, home Internet access, and stable residency were eligible. Families were randomized to standard of care (SOC) or telemedicine (TELE);virtual assessments were performed at 2, 4, and 6 months. Data included demographics and standardized assessment of the home environment. Results: Eighteen participants were enrolled (9 TELE, 9 SOC). There were no significant differences in baseline demographics between groups. Sensitization to pollens and dust mites was most common in both groups. Housing conditions were similar. In both groups, 89% lived in detached homes with forced air (standard filter) being the most common heating source (33%). Visible signs of pests/mold were seen in <12%. 89% use scented air fresheners/candles/potpourri. The SOC group had more pets (67% versus 33%) and smoking in the home (22% versus 11%). There was less evidence of mold in the TELE group (0 versus 22%). All SOC participants use bleach/ammonia cleaning products (78% in TELE). Thirteen participants (72%) completed at least one virtual home visit. No significant barriers were identified to telemedicine encounters. All participants reported “completely” or “very” satisfied with telemedicine visits. Conclusions: Virtual home assessments for identification of asthma triggers is a feasible alternative to in-person home visits, and it is well accepted by patients.
