Hubungan Kadar Kreatinin Saat Masuk Rumah Sakit dengan Length of Stay Pasien Heart Failure with Reduced Ejection Fraction (HFrEF) di RSUP HAM Medan Periode April 2023-April 2024

Abstract

Introduction. Heart failure is the final stage of heart disease and is the leading cause of increased morbidity and mortality among heart patients. Patients with heart failure are more susceptible to kidney function deterioration, which can be measured by serum creatinine levels. The increase in creatinine levels, along with worsening kidney function, complicates about one-third of heart failure patients, which is associated with an increased length of stay, rehospitalization rates, and both short-term and long-term mortality. Objective. This study aims to determine the relationship between serum creatinine levels at hospital admission and the length of stay in patients with heart failure with reduced ejection fraction (HFrEF) at RSUP HAM Medan during the period of April 2023 to April 2024. Methods. This study uses an analytical method with a cross-sectional study design and total sampling technique. The sample size for this study is 90 patients. Results. The results of statistical analysis using the Spearman test show a significant relationship between creatinine levels and the length of stay of HFrEF patients (p=0.034). Conclusion. There is a significant relationship between serum creatinine levels and the length of stay in HFrEF patients.
