Adults (aged 18-64 years) undergoing ESS for CRS in 2012-2015 were identified within the Blue Health Intelligence® database and used to estimate revision rates. Patients with ±1 year of enrollment around the index ESS were used to estimate 1-year healthcare expenditures. Revision ESS rates were evaluated via Kaplan-Meier and Cox regression models. Disease-related healthcare and pharmacy expenditures were modeled with generalized linear regression to assess the impact of baseline patient characteristics.
