Population‐based study of congenital heart disease and revisits after pediatric tonsillectomy

Abstract

Objective

Accurate assessment of risk factors such as congenital heart disease (CHD) can aid in risk stratification of children presenting for surgery. Risk stratification is especially important in tonsillectomy ± adenoidectomy (T/A), a common pediatric procedure that is usually performed electively, but that has a high rate of adverse events. In this study, we examined the association of CHD with revisits after T/A.

Methods

We identified children who underwent T/A at hospitals and hospital‐owned facilities during 2010 to 2014 using the State Inpatient Databases and State Ambulatory Surgery and Services Databases of Florida, Georgia, Iowa, New York, and Utah. We evaluated the association between CHD severity and the occurrence of an unplanned hospital readmission or ED visit within 30 days following discharge using multivariable logistic regression.

Results

The analysis included 244,598 patients, of whom 858 had minor or major CHD. In multivariable analysis, CHD was not associated with an increased risk of 30‐day revisits (minor OR = 1.1; 95% CI: 0.8, 1.5; P = .65; major OR = 1.2; 95% CI: 0.9, 1.6; P = .34). Other comorbidities, including chromosomal anomalies (OR = 1.4; 95% CI: 1.2, 1.6; P < .001), congenital airway anomalies (OR = 1.3; 95% CI: 1.03, 1.7; P = .03), and neuromuscular impairment (OR = 1.4; 95% CI: 1.2, 1.7; P < .001) predicted an increased likelihood of revisits.

Conclusion

Neither minor nor major CHD was independently associated with an increased risk of 30‐day revisits among children undergoing T/A. Other characteristics, particularly non‐cardiac comorbidities, socioeconomic status, and geographic region may be of greater utility for predicting revisit risk following pediatric T/A.
