Associations of community-level particulate matter with high-acuity visit presentation for sinusitis.

BACKGROUND: Exposure to particulate matter <2.5 µm in diameter (PM2.5) has been linked to increased sinusitis prevalence and morbidity. However, studies analyzing environmental exposures and sinusitis have not explored the effect of PM2.5 on healthcare presentation patterns. OBJECTIVE: This study aims to characterize the relationship of community-level PM2.5 with high-acuity visits in sinusitis patients. METHODS: A retrospective analysis based on medical records of 2092 adults presenting with chronic rhinosinusitis, acute rhinosinusitis, or sinus/nasal polyps to an urban academic medical center from 2010 to 2019 was conducted. We linked medical records (individual-level) with data on PM2.5 exposure at the community level, using residential zip-code data from the Chicago Health Atlas covering the years 2015-2019. Multivariable binary logistic regression with Generalized Estimating Equations examined adjusted associations between PM2.5 and high-acuity visits - including emergency department and inpatient settings. RESULTS: Our sample was 69 % female, with a mean age of 46.9 years. From 2015 to 2019, the average PM2.5 exposure in zip-codes examined was 11.66 µg/m3 with a range of 11.14-11.79 µg/m3. In adjusted models, odds of a high-acuity visit were significantly higher in patients residing in zip-codes in the top tertile of PM2.5 exposure compared to the bottom tertile (OR: 1.74; CI: 1.20-2.51). CONCLUSION: Community-level PM2.5 exposure was associated with high-acuity visits among sinusitis patients. These associations need to be studied through more rigorous, prospective investigations, as they may have potential public health implications and underscore a need to mitigate PM2.5 exposures at a community-level.

Demographic Factors and Comorbid Conditions Related to Health Care Presentation Among Patients With Sinusitis.

BACKGROUND: Social determinants of health (SDOH) and comorbid conditions (CMCs) influence the setting of presentation for care; however, few studies have explored this relationship in the context of sinus disease. OBJECTIVE: This study aims to characterize the relationship of SDOH and CMCs with acuity of health care presentation setting in adults with sinusitis. METHODS: A retrospective analysis based on medical records (demographics, visit types, and ICD-10 codes) of 1842 adult patients presenting with sinusitis to an urban academic medical center was conducted. Chi-square analysis was used to assess bivariate associations of SDOH (age, race/ethnicity, sex, insurance type, and employment status) and CMCs (depression, body mass index [BMI], allergy, and gastroesophageal reflux disease [GERD]) with high-acuity visit types-including emergency department (ED) and inpatient visits. Multivariable binary logistic regression was performed to examine the adjusted associations between SDOH and high-acuity visits. RESULTS: The sample's mean age was 46.8 years, with 68.5% females and 31.5% males. In adjusted models, the odds of high-acuity visit presentation was higher for males than females (odds ratio [OR]: 1.57; confidence interval [CI]: 1.22-2.01); non-Hispanic Blacks (OR: 2.21; CI: 1.58-3.09) as well as Hispanics/Latinos (OR: 2.10; CI:1.43-3.08) than Whites; unemployed (OR: 1.90; CI: 1.47-2.46.) than employed. Age was positively associated with high-acuity presentation. While GERD was associated with increased odds of high-acuity presentation (OR: 2.80; CI: 1.64-4.78), BMI, allergy, and depression did not have a statistically significant association with these visit types. These associations were independent of insurance coverage, which was not statistically associated with high-acuity visits. CONCLUSION: SDOH and CMCs were associated with high-acuity healthcare presentation in adults with sinusitis. While this study highlights how SDOH affect healthcare usage patterns among people with sinusitis, further investigation is needed to identify and address the causes of these patterns.
