Methods: Using data from the Taiwan National Health Insurance Research Database for the 1997–2012 period, all inpatients <18 years who received adenoidectomies were identified by codes from the International Classification of Diseases, 9th Revision. Results: A total of 20,599 children underwent adenoidectomy (mean age, 7.4 years; 67% boys). The overall incidence rate was 24.5 per 100,000 children. The highest incidence was observed for the ages of 3–5 years in both genders (p <.001). Boys exhibited higher incidence rates than did girls (p <.001). Longitudinal data revealed an increase in the incidence rates from 1997 (14.8/100,000) to 2012 (26.9/100,000) (p trend <.001). The proportion of adenoidectomies performed at medical centers decreased from 60.5 to 46.9%, whereas those performed at regional hospitals increased from 36.4 to 47.2% (all p trend <.001). The proportion of pediatric adenoidectomies performed for sleep-disordered breathing (SDB) increased significantly from 10.1 to 35.6%, whereas those for infections decreased from 32.3 to 8.0% (all p trend <.001). Conclusions: This study revealed an increasing trend of pediatric inpatient adenoidectomy incidence rates during 1997–2012 in Taiwan. Moreover, surgical indications have shifted from infections to SDB. ? 2017 Acta Oto-Laryngologica AB (Ltd).[SDGs]SDG3adenoid hypertrophy; adenoidectomy; adolescent; age distribution; Article; child; controlled study; female; gender; hospital; human; incidence; infant; major clinical study; male; newborn; otitis media; perioperative period; population research; priority journal; rhinitis; sinusitis; sleep disordered breathing; Taiwan; tonsillitis; treatment indication; trend study; adenoidectomy; preschool child; retrospective study; statistics and numerical data; Adenoidectomy; Adolescent; Child; Child, Preschool; Female; Hospitals; Humans; Infant; Male; Retrospective Studies; Taiwanjournal article10.1080/00016489.2017.1357191287492432-s2.0-85026372575
