Background: Electrophysiologic (EP) and structural interventions in adult congenital heart disease (ACHD) are typically completed during separate hospital encounters. With planning/coordination, these cases can be combined.
Objectives: We hypothesized that this integrated approach would yield patient and health system benefits.
Methods: Consecutive ACHD patients undergoing combined interventions were matched to controls with identical but separate procedures. Primary endpoints of total hospital length of stay and cost were compared.
Results: Sixty-six combined cases and 120 controls were identified (45% male, mean age 36.2 ± 14.2 years). The most common diagnoses were Fontan (27%), tetralogy of Fallot (23%), and transposition complexes (20%). The most common EP procedure was catheter ablation (n = 30) followed by electrophysiologic study (n = 13); the most common structural intervention was transcatheter valve replacement (n = 16) followed by angioplasty/stenting (n = 14). Compared to controls, cases showed shorter anesthesia duration (323 [IQR 238-405] vs. 355 minutes [270-498], P = 0.06), smaller contrast dose (130 [50-189] vs. 177 mL [94-228], P = 0.045), fewer venipunctures (4 [3-4] vs. 6 [5-7], P < 0.001), and fewer work days missed (2 [2-5] vs. 4 [4-6], P < 0.001). There was shorter hospital stay (30 [19-35] vs. 38 hours [26-50], P = 0.023) and a 37% reduction in hospital charges ($117,894 vs. $187,648; P = 0.039) and 27% reduction in payments ($65,757 vs. $88,859; P = 0.016), persisting after adjustment for group differences. There were no significant differences in number of complications or efficacy.
Conclusions: There appear to be advantages to combining ACHD interventional procedures that include reductions in hospital length of stay and cost, without detectable difference in procedural outcome.
