Abstract: 【Abstract】Objective To investigate knowledge, attitude, belief and practice towards phosphorus-based additives among hemodialysis patients in order to improve the health education of phosphorus-based additives for the patients. Methods We used self-designed questionnaire and convenient sampling method to investigate knowledge, attitude, belief and practice towards phosphorus- based additives in hemodialysis patients. Results The total score of the questionnaire was 29.15±5.43 points, corresponding to a moderate level. The score of pain knowledge was 8.36±3.55, the score of pain attitude was 13.72±1.81, and the score of analgesic behavior was 7.07±2.18. According to Pearson correlation analyses, knowledge and attitude were positively correlated with attitude and behavior (P<0.01), but no correlation was found between knowledge and behavior (P>0.05). Conclusion Knowledge, attitude, belief and practice health education model should be adopted to improve knowledge, attitude and behavior towards phosphorus-based additives to control serum phosphorus level in hemodialysis patients.
