The geriatric nutritional risk index may predict healthcare costs and health transitions during hemodialysis in China.

BACKGROUND AND OBJECTIVES: The aim of the present study was to retrospectively analyze the relationship between the Geriatric Nutritional Risk Index (GNRI) at baseline and healthcare costs of three-month as well as the risk of quality-of-life score at the 6-month follow-up for Chinese hemodialysis patients.

METHODS AND STUDY DESIGN: One hundred patients who had been on maintenance hemodialysis were enrolled in this study. The general characteristics, laboratory test results and GNRI of the patients at baseline were recorded. The healthcare costs and quality-of-life scores were determined at the follow-up examination.

RESULTS: Patients were divided into two groups according to their median GNRI at baseline: a lower GNRI group (GNRI <86.4) and a higher GNRI group (GNRI >86.4). The patients in the lower GNRI group exhibited reduced hemoglobin (74.7±13.1 g/dL vs 82.3±15.2 g/dL, p<0.05) and albumin (27.4±3.3 g/L vs 34.5±4.0 g/L, p<0.05) as well as reduced body weight (62.7±9.5 kg vs 68.0±9.2 kg, p<0.05) at baseline. The medication cost at follow-up was higher in the lower GNRI group (RMB 3,238±1,534 vs RMB 2,378±1,048, p<0.05). And a lower GNRI at baseline was associated with increased future medication costs and worse health in hemodialysis patients.

CONCLUSIONS: The present study suggests that a lower GNRI in hemodialysis patients may be associated with an increased risk of higher future healthcare costs as well as worse health.
