Abstract
Study objective: Assess the prevalence of and risk factors for pediatric pulmonary hypertension (PH) in the 2016 Kids’ Inpatient Database (KID), including obstructive sleep apnea (OSA) and obesity.
Methods: Retrospective cross-sectional cohort study utilizing 6,081,132 weighted pediatric discharges from the 2016 KID. Study variables included age, length of stay, mortality, gender, hospital region, primary payer, race, median household income for patient’s ZIP code, OSA, central sleep apnea (CSA), obesity, Down syndrome, sickle cell disease (SCD), thalassemia, congenital heart disease (CHD), hypertension, asthma and chronic lung disease of prematurity (CLDP). PH was the primary outcome of interest. Bivariate and multivariable logistic regression models were utilized with odds ratios and 95 % confidence intervals.
Results: The mean age was 3.76 years, the mean hospital length of stay was 3.85 days, 48.9 % were male, 52.6 % had government health insurance, 51.0 % were White, 16.1 % were Black, 21.1 % were Hispanic, 5.0 % were Asian or Pacific Islander, 0.80 % were Native American and 6.1 % identified as “other”. The prevalence of PH was 0.21 % (12,777 patients). There were 37,631 patients with OSA and the prevalence of PH among this cohort was 3.3 %, over 10x greater than the overall prevalence of PH in the 2016 KID (0.21 %). Risk factors associated with PH included CLDP, CHD, Down syndrome, asthma, OSA, CSA, hypertension, SCD, obesity, race/ethnicity, government insurance, age, male gender (p < 0.0001), and hospital region (p = 0.0002).
Conclusions: Several risk factors were independently associated with PH, such as OSA, CSA, obesity, asthma, and insurance status. Prospective multi-institutional studies are needed to assess the relationships between these risk factors, severity metrics, and causative links in the development of PH; in addition to identifying children with OSA who are most likely to benefit from cardiopulmonary screening prior to adenotonsillectomy.
