Mental health diagnoses in hospitalized adults with congenital heart disease in the state of Texas: A 10-year review

Background: Adults with congenital heart disease (ACHD) face psychological challenges. Furthermore, ACHD patients experience an under-recognition of mental health disorders (MHD). Understanding the impact of MHDs on ACHD hospitalizations may better inform and help re-design the ACHD care model. Methods: A retrospective review of the Texas Inpatient Discharge Dataset (TIDD) was performed. Data was queried across a ten-year period, from the beginning of 2009 to the end of 2018.

ACHD patients with MHD had a longer length of stay (LOS) compared to those without (5 [3-8] vs. 4 [2-7] days, p
