Background: Adult congenital heart disease (ACHD) patients are at risk of anxiety and depression. In the general population anxiety/depression were reported to be associated with high healthcare resource utilizations. Little is known about the association between anxiety/depression and healthcare resource utilization among ACHD patients.
Methods: Analysis comprised 8334 ACHD patients, age ≥18 years, insured by Maccabi Health Services during the studied period (2007-2011). Anxiety/depression were determined by diagnosis (ICD-9: 296.2-296.36, 311, 300.0, 300.2, 300.4) and treatment (ATC code: N06A).
Findings: Anxiety/depression were documented among 2950 (35%) ACHD patients. Patients with anxiety/depression were significantly more likely to be women (61% vs. 45%), older (mean±SD: 53±18 vs. 45±17 years) and to have cardiac disease manifestations (such as arrhythmia, heart failure, cardiovascular and other heart disease) and co-morbidities than anxiety/depression free counterparts. During the studied period, more anxiety/depression patients consulted with a cardiologist (86% vs 79%), visited an emergency department (ED; 58% vs. 45%) or were hospitalized (53% vs 39%) than patients without anxiety/depression.
Healthcare utilization rates associated with anxiety/depression were age dependent, with the highest relative rates (RR) among younger adults and the lowest among older adults. The highest multivariable negative binomial adjusted RRs (95% confidence interval) were: 1.75 (1.58-1.95) for GP visits; 1.53 (1.26-1.86) for cardiology consultations; 1.52 (1.11-2.08) for ED visits; all among age 18-24 years, and 1.55 (1.35-1.79) for hospitalizations among age 25-44. Lowest RRs were: 1.11 (1.05-1.17); 1.00 (0.91-1.10); 1.34 (1.13-1.59); and 1.23 (1.07-1.41) respectively, among age 65 years or older.
Conclusions: ACHD patients with anxiety/depression have increased relative healthcare services utilization rates particularly among younger patients. Addressing patient psychosocial needs might save unnecessary utilizations and improve ACHD patient prognosis.
