Aims: The main aim of the present study was to report the annual volume of surgeries performed for chronic rhinosinusitis with nasal polyps (CRSwNP) in France, based on health insurance data. The secondary objectives were to describe the different characteristics of the surgeries and their complications, and to estimate the number of patients eligible for biotherapy.
Material and methods: This was a descriptive observational retrospective study using data from French national health insurance databases for the period 2011-2018. Inclusion criteria comprised all hospital stays with procedures related to CRSwNP according to the French Common Classification of Medical Acts and consistent with French practices.
Results: Ninety-two thousand one hundred and fourty one patients (92,141) for 92,884 admissions for CRSwNP surgery were analyzed, providing an accurate representation of CRSwNP surgery in France between 2011 and 2018. The revision surgery rate for patients operated on in 2011 was 13.0% (1,457/11,212), corresponding to an average annual rate of 1.86% over 7 years. In the 11,750 sinus surgery admissions in 2018, the complications rate was only 0.65% (77/11,750).
Conclusion: Sinus surgery is safe (0.65% complications) and reliable (estimated revision rate, 5.5%: 5,078/92,884). This study provides the first evaluation of the target population for biotherapy in France.
