[II-JCKAP4-3] Incidence and current clinical practice for all-cause morbidity in patients with Fontan circulation (Japan Fontan Registry: JFR)
Keywords:Fontan circulation, morbidity, hospitalization
Objective: To clarify the incidence and clinical practice of unscheduled hospitalization (USH) in patients with Fontan circulation (FC). Method: We conducted a multi-center prospective study with 3-year registration of USH FC patients.Results: We followed 3225 FC patients in 20 institutions and 243 (7.5%) patients encountered USH. The most common cause was heart failure (HF, 19.3%), followed by infection (18.9%) and protein losing enteropathy (PLE, 16.5%), hemorrhage (13.2%), arrhythmia (9.5%), thromboembolism (TE, 2.5%), plastic bronchitis (1.6%), and others (17.7%). O2 inhalation was the most common non-pharmacological managements (38%), followed by surgery (12%), and catheter intervention (10%), while diuretics (iv) was the most common pharmacological managements (28%), followed by antibiotics (iv) (28%), and heparin (iv) (11%). Overall median USH-stay (days) was 9 and the longest stay was due to PLE (20), followed by TE (17) and HF (13). After discharge, 76 (31%) patients re-hospitalized with the highest cause of PLE (34%), followed by HF (16%) and hemorrhage and infection (13% for each). Leukopenia and hypoproteinemia at discharge were independently associated with a high risk of re-USH (p<0.05). Conclusions: We clarified current practices in FC patients in Japan. Further analyses of each USH are necessary for establishing management strategy.
