Dialysis Model for Outcome and Nutrition Decision

This study is the secondary phase of Taiwan Prediction Model Project Plan (TPMPP). The investigators try to design a prospective randomized control trial with nutrition intervention to validate 3 prediction models the investigators developed in the first phase. Proper validation of these models is mandatory before they can be applied and implemented into daily clinical practice. At present, around 20 centers with estimated around 550-650 high-risk patients will be enrolled with 1:1 ratio in study and control groups. Following up of parameters about primary and secondary outcomes will be done in both groups. But a pre-designed intervention protocol, which is according to 3 elucidated screening methods, will be applied only to the study group. The total study period will be one year.
