A novel risk score for disease control prediction of chronic rhinosinusitis

Clin Otolaryngol. 2022 Sep;47(5):568-576. doi: 10.1111/coa.13949. Epub 2022 Jun 30.


Objectives: To assess the impact of risk factors on the disease control among chronic rhinosinusitis (CRS) patients, following 1 year of functional endoscopic sinus surgery (FESS), and combining the risk factors to formulate a convenient, visualised prediction model.

Design: A retrospective and nonconcurrent cohort study.

Setting and participants: A total of 325 patients with CRS from June 2018 to July 2020 at the First Affiliated Hospital of Sun Yat-sen University, the Third Affliated Hospital of Sun Yat-sen University, the Seventh Affiliated Hospital of Sun Yat-sen University.

Main outcomes measures: Outcomes were time to event measures: the disease control of CRS after surgery 1 year. The presence of nasal polyps, smoking habits, allergic rhinitis (AR), the ratio of tissue eosinophil (TER) and peripheral blood eosinophil count (PBEC) and asthma was assessed. The logistic regression models were used to conduct multivariate and univariate analyses. Asthma, TER, AR, PBEC were also included in the nomogram. The calibration curve and area under curve (AUC) were used to evaluate the forecast performance of the model.

Results: In univariate analyses, most of the covariates had significant associations with the endpoints, except for age, gender and smoking. The nomogram showed the highest accuracy with an AUC of 0.760 (95% CI, 0.688-0.830) in the training cohort.

Conclusions: In this cohort study that included the asthma, AR, TER, PBEC, which had significantly affected the disease control of CRS after surgery. The model provided relatively accurate prediction in the disease control of CRS after FESS and served as a visualised reference for daily diagnosis and treatment.
