Abstract

Background: This study evaluated short-term (1-month) and long-term (1-year) mortality risks associated with kidney function measured by estimated glomerular filtration rate (eGFR) levels at admission for patients with intracerebral hemorrhage. Methods: From the Taiwan Stroke Registry data, we identified and stratified patients with intracerebral hemorrhage into 5 subgroups by the eGFR levels at admission: ≥ 90, 60-89, 30-59, 15-29, and < 15 mL/min/1.73m2 or on dialysis from April 2006 to December 2016. Risks of 1-month mortality and 1-year mortality rates after intracerebral hemorrhage were investigated by the eGFR levels. Results: Both the 1-month mortality and 1-year mortality rates increased as the eGFR level decreased. The 1-month mortality rate was over 5-fold greater in patients with eGFR < 15 mL/min/1.73m2 or on dialysis than in patients with eGFR levels ≥ 90 mL/min/1.73m2 (8.31 versus 1.50 per 1000 person-days), with an adjusted hazard ratio (HR) of 4.59 [95% confidence interval (CI) = 2.71-7.78]. Similarly, the 1-year mortality rate was 7.5-fold greater in patients with eGFR < 15 mL/min/1.73m2 or on dialysis than in patients with eGFR ≥ 90 mL/min/1.73m2, with an adjusted HR of 4.54 (95% CI 2.95-6.98). Conclusion: The eGFR level can be an indicator of prognosis for patients with intracerebral hemorrhage.
