Abstract
BackgroundRecently, discussions have increasingly focused on “withdrawal from dialysis” among patients undergoing dialysis who experience severe brain dysfunction as post-stroke sequelae. In this context, the lack of understanding regarding functional prognosis after spontaneous intracerebral hemorrhage in patients undergoing hemodialysis becomes a particularly important issue. Therefore, we aimed to evaluate the functional prognosis of intracerebral hemorrhage in patients undergoing hemodialysis when life-saving was prioritized and dialysis was not withdrawn. Furthermore, we sought to identify factors influencing life and functional prognosis.MethodsWe retrospectively analyzed data of 100 consecutive hemodialysis patients who experienced spontaneous intracerebral hemorrhage between 2012 and 2021. The in-hospital mortality rates and modified Rankin Scale (mRS) and Functional Independence Measure (FIM) scores at discharge and 90 days after onset were examined.ResultsThe mean age of the patients was 65.7 years, with 29% of them undergoing life-saving brain surgery. The mRS score at discharge was 0, 1, 2, 3, 4, 5, and 6 (indicating death) in 0, 1, 13, 9, 26, 20, and 31 cases, respectively. Among the 69 surviving patients, the median FIM score at discharge was 37 (19–81), with 14 patients having an FIM score of 18 (i.e., complete dependence). Patients who underwent life-saving brain surgery showed a higher median mRS score [5, interquartile range (IQR) 5–6] and a lower FIM score (18, IQR 18–22) at discharge compared with those who did not undergo the surgery. Patients discharged with mRS and FIM scores of 5 and 18, respectively, had the same functional status at 90 days. The Functional Outcome in Patients With Primary Intracerebral Hemorrhage (FUNC) score and intraventricular extension at admission were predictive of a mRS score ≥ 5 (area under the receiver operating characteristic curve = 0.92, p < 0.0001) and FIM score at discharge (adjusted R2 = 0.3, p = 0.0003).ConclusionIn our single-center study, more than 14% of patients on hemodialysis with cerebral hemorrhage incurred severe, irreversible neurological and functional impairments, necessitating discussions on hemodialysis withdrawal. Moreover, FUNC score and intraventricular extension at admission were highly accurate predictors of functional prognosis.
