Cardiac genetic counseling services: Exploring downstream revenue in a pediatric medical center.

Genetic counseling is an important component of pediatric cardiac care. The financial costs and benefits of this care have yet to be defined in the literature. Downstream revenue (DSR) analysis can be used to assess the economic impact of genetic counselors (GCs) at their institution beyond the initial patient contact. Previous literature has reported DSR generated by oncology GCs, but there is no published DSR data from a cardiac GC setting. This study measured the DSR generated at a private hospital following a cardiac GC appointment. A chart review identified patients seen by a cardiac GC between 2018 and 2022. The study population included patients and their pediatric relatives who had not previously seen a cardiologist. Patients were included if they were affected with or at-risk for long QT syndrome, hypertrophic cardiomyopathy, dilated cardiomyopathy, or familial thoracic aortic aneurysm at the time of the GC visit. We recorded the frequency of common cardiac services and calculated the reimbursement for all cardiology services for 1 year following the initial GC appointment. The cohort included 121 participants from 61 families. Most individuals were at-risk for (n = 114, 94.3%) rather than affected by an inherited cardiac condition and presented for screening. The total DSR was $247,592.27, with an annual median of $1819.50 per patient (IQR $0, $3761.33). Revenue was similar among individuals who had undergone genetic testing and those who had not. Among participants, 72 (59.5%) had subsequent cardiology services. Most frequently, a patient who presented for subsequent care had an EKG, an echocardiogram, and a cardiology appointment. While the economic contributions of GC services do not speak to the broader value of GC involvement in patient care, they are important metrics for sustainability. This study outlines an approach to evaluating DSR and establishes a baseline understanding of DSR related to cardiac GC services.
