National changes in pediatric tracheotomy epidemiology during 36 years.

BACKGROUND: Information on the incidence, indications and morbidity of pediatric tracheotomy from a nationwide setting is sparse.

METHODS: From the nationwide Danish National Patient Registry, we identified all cases: 0-15-year-old children registered with a first-time tracheotomy from 1979 to 2014. We extracted the date of surgery, admission, discharge, age, gender, hospital, department, hospitalization length, hospital contacts, and diagnosis-code related to the surgery. We estimated age-adjusted incidence rates (AAIR) and annual (APC) and average annual percentage change (AAPC) of tracheotomy incidence.

RESULTS: A total of 510 children (328 boys, 63%) underwent tracheotomy. The median age at surgery was 8 years. The AAIR was 1.4/100,000 person-years (range 1.0-1.8) from 1980 to 2014. During 1979-2014, the AAPC decreased - 0.9% (95% confidential interval - 2.4; 0.8, p < 0.3). From 1979 to 2003 the APC decreased - 4.1% (95% CI - 5.4; - 2.8, p < 0.001) and from 2003 to 2014 the APC increased 6.6% (95% CI 2.0; 11.5, p < 0.001). Infants had the highest incidence (4.0/100,000 years) compared with the 12-15-year-olds (AAIR: 0.4/100,000 years). From 1979 to 2014 the most common indication for tracheotomy among children aged 0-2 years was congenital malformations (n = 48, 30%) and among children aged 3-11 and 12-15 years the most common indication was trauma (respectively n = 67, 36% and n = 85, 52%). During 2006-2014 the most common indications for all ages was neurological impairment (n = 25, 21%) and neoplasms (n = 20, 17%).

CONCLUSIONS: Pediatric tracheotomy was a rare surgical procedure with decreasing incidence rates from 1980-89 to 1990-99 and increasing incidence rates from 2000-2009 to 2010-2014. Indications and postoperative morbidity have changed adjunct to the treatment of chronic disorders.
