Nationwide Frequency, Sequential Trends, and Impact of Comorbid Mental Health Disorders on Hospitalizations, Outcomes, and Healthcare Resource Utilization in Adult Congenital Heart Disease

ABSTRACT Despite the growing prevalence of adult congenital heart disease (ACHD), data on trends in prevalence of mental health disorders (MHD) among patients with ACHD remain limited. The National Inpatient Sample (2007-2014) was queried to identify the frequency and trends of MHD among ACHD hospitalizations (stratification by age, sex, and race); demographics and comorbidities for ACHD cohorts, with (MHD+) vs. without MHD (MHD-); the rate and trends of all-cause in-hospital mortality, disposition, mean length of stay (LOS), and hospitalization charges among both cohorts. A total of 11,709 (13.8%, mean age: 49.1 yrs., 56.0% females, 78.7% white) out of 85,029 ACHD patient encounters had a coexistent MHD (anxiety, depression, mood disorder, or psychosis). ACHD-MHD+ cohort was more often admitted non-electively (38.1% vs. 32.8%, p
