Background: Few studies have investigated the relationship between chronic obstructive pulmonary disease (COPD) and chronic rhinosinusitis without nasal polyps (CRSsNP) outcomes. The aim of this study was to investigate the association between COPD and the risk of CRSsNP in a large national sample. Methods: Patients 15 years or older with a new primary diagnosis of COPD (International Classification of Diseases, Ninth edition [ICD-9], 491, 492, 494, and 496) between 2000 and 2007 were identified from the National Health Insurance Research Database of Taiwan. The patients were compared with sex-, age-, residence-, and insurance premium-matched controls, and both groups were followed up until the end of 2008 for instances of CRSsNP, defined as ICD-9 codes CRS (473, 473.0, 473.1, 473.2, 473.3, 473.8, and 473.9), excluding NP (471, 471.0, 471.1, 471.8, and 471.9). Competing risk-adjusted Cox regression analyses were applied after adjusting for sex, age, residence, insurance premium, steroid use (topical or systemic), hyperlipidemia, diabetes, hypertension, coronary artery disease, hospital admission days, and mortality. Results: We included 34,029 cases and 34,029 matched controls in this study. Among the 68,058 subjects, 569 developed CRSsNP during a mean (standard deviation [SD]) follow-up period of 5.0 years (SD 2.2 years). COPD was an independent predictor of CRSsNP in the fully adjusted model (hazard ratio = 3.24; 95% CI = 2.65-3.96; p < 0.01). Conclusion: COPD was associated with an increased risk of CRSsNP in this study population, independent of a number of potential confounding factors.
