Long-term Out-of-Hospital Health Care Use for Fontan Survivors Across Childhood

Background. Surgery is the cornerstone of treatment for single-ventricle patients, but life just begins for most when the staged procedures are completed. A package of care, including primary care, out-of-hospital specialist visits, and medication, is required for patients living with Fontan. This study quantified the current state of out-of-hospital health care use across childhood for Fontan patients using evidence from Australia. Methods. Patients recruited from the Fontan Registry were linked with the administrative Medicare (universal health insurance) data. Frequency of medical and pharmaceutical care and costs were estimated. Results. Data for 115 patients with 12,726 medical and 8,336 pharmaceutical claims were obtained. From age 0 to 20 years, patients on average visited a general practitioner an estimated 6.4 times per year (95% confidence interval [CI], 5.9-7.0 times per year), and specialists, including cardiologists, 2.8 times per year (95% CI, 2.5-3.0 times per year). Average use of allied health professional care peaked at age 6 to 9 years (1.0 visits per year; 95% CI, 0.7-1.4 visits per year) with psychologic services being most prominent. For pharmaceuticals, an average of 13.3 prescriptions filled per patient per year throughout childhood was observed (95% CI, 12.4-14.2 prescriptions per year). Overall, out-of-hospital doctor visits of all types averaged 11 visits per year from birth to 20 years. A decline in care was observed when patients reached 18 years across services. Conclusions. Patterns of out-of-hospital health care use were observed; however, current guidelines are silent about whether this is optimal. Further research is needed to better understand the comprehensive needs of this population. (C) 2020 by The Society of Thoracic Surgeons
