Factors Associated with Severe RSV Outcomes
Factors associated with severe RSV outcomes were assessed with bivariate analysis (Table 1). Neither age nor any of the comorbid conditions assessed were associated with increased odds of experiencing severe RSV infection. Patients who resided in assisted living, skilled nursing, long-term care, rehabilitation, or hospice facilities at admission (Level 3) had a 4.43 times higher likelihood of severe RSV outcomes compared with other living situations.
The results from the logistic regression analysis are shown in Table 2. Multiple models were tested, including age stratified models assessing multiple different comorbidities as well as clinically and statistically significant variables from the bivariate analysis. In the final model, those with a living situation of Level 3 had 6.64 times higher odds of severe RSV infection compared to those admitted from other living situations, while controlling for age, sex, and comorbidities.
