Assessing the predictive power of nutritional indices on all-cause and cardiovascular mortality in hemodialysis patients: a longitudinal study.

ABSTRACT:

Background and hypothesis

The prognostic value of nutritional scoring tools in assessing the relationship between nutritional status and prognosis in hemodialysis patients is unclear. This multicenter retrospective cohort study compared the Prognostic Nutritional Index (PNI), Controlling Nutritional Status scores (CONUT), and Geriatric Nutritional Risk Index (GNRI) for predictive accuracy of all-cause and cardiovascular mortality, especially the impact of dynamic changes over time on prognosis.

Methods

Hemodialysis patients from four hospitals were included. Laboratory data and nutrition scores were collected at the initiation of dialysis, and at 6th, 12th, and 18th months after dialysis initiation. A joint model analyzed the relationship between dynamic nutritional scores a
