ĐẶC ĐIỂM CHỈ SỐ BỆNH ĐI KÈM CHARLSON VÀ MỘT SỐ YẾU TỐ LIÊN QUAN Ở NGƯỜI BỆNH LỌC MÁU CHU KỲ

Abstract

Objectives: To evaluate the characteristics of the Charlson comorbidity index (CCI) and identify associated factors in patients undergoing maintenance hemodialysis (MHD). Methods: A cross-sectional descriptive and analysed study was conducted on  114  MHD  patients  at  Military  Hospital  103  from  June  2025  to  May  2026. Data were collected from medical records and direct patient interviews. Collect clinical and paraclinical data and assess CCI using the Vietnamese-adapted Charlson scale. Results: The mean age of the patients was 58.99 ± 14.07 years, with males accounting for 52.6%. The mean duration of dialysis was 67.38 ± 55.99 months. The mean CCI score was 3.74 ± 1.52; the majority of patients had a CCI ≤ 4 (72.8%), while only 4.4% had a CCI ≥ 7, indicating a mild-to-moderate comorbidity burden. The most common comorbidities were heart failure, chronic liver disease, and diabetes mellitus. The CCI score increased with age and showed significant associations with serum albumin and hemoglobin levels, suggesting that comorbidity burden may reflect nutritional status. Conclusion: Most MHD patients had a mild-to-moderate comorbidity burden. The CCI score increased with age and was strongly associated with nutritional indicators, particularly albumin and hemoglobin. The CCI is a supportive tool for risk assessment and stratification in MHD patients.
