Objectives: To characterise the real‐world burden of chronic rhinosinusitis with nasal polyps (CRSwNP) in the UK, stratified by number of surgeries. Design: Retrospective cohort study. Setting: UK Clinical Practice Research Datalink Aurum database with Hospital Episodes Statistics linkage (2007–2019). Participants: Adults ≥18 years of age with a first NP diagnosis (index) and 365 days of baseline and ≥180 days of follow‐up data. Follow‐up continued until disenrollment, death or end of data collection. Main Outcome Measures: Primary: primary care physician prescribed CRSwNP‐related treatments, and all‐cause healthcare resource utilisation (HCRU) in 90 days post‐index, stratified by surgeries during follow‐up. Secondary: rate of surgery and CRSwNP point prevalence. Baseline patient demographics, clinical characteristics and comorbidities were also assessed. Results: Of the 33 107 patients included, 23.5% and 2.2% had ≥1 and ≥2 surgeries during follow‐up, respectively (mean follow‐up: 5.3 years). Patients with more surgeries (≥2/≥1/0) during follow‐up were more likely to be male (67.3%/69.0%/58.0%), have asthma (37.8%/28.2%/20.2%) and have baseline blood eosinophil counts ≥300 cells/μL (68.5%/66.0%/51.5%). During the first 90‐days post‐index as surgery number increased, the proportion of patients using oral corticosteroids (25.8%/20.7%/14.2%) and mean (SD) number of all‐cause healthcare visits (5.9 [4.2]/5.4 [4.0]/4.9 [4.2]) increased. Time between surgeries was shorter among patients with more surgeries. CRSwNP prevalence on 31 December 2018 was 476 cases per 100 000 persons. Conclusion: A small proportion of patients in the UK required multiple surgeries for CRSwNP and this was associated with increasing comorbidity burden, baseline blood eosinophil counts, CRSwNP‐related treatment and HCRU use.
