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.
