Abstract
BACKGROUND Hyperphosphatemia is a common complication in patients on maintenance hemodialysis. Patients' adherence to phosphorus control can be improved by consistent education. However, few studies have focused on the model construction and effects of health education on phosphate control for hemodialysis patients. OBJECTIVE To develop an intensive education program focusing on phosphate control among hemodialysis patients and to analyze the effectiveness of this program. DESIGN A non-randomized, single-arm, single-center trial lasting for 6 months. SETTING This program was conducted in a hemodialysis center in a teaching hospital in Zhuhai, China. PARTICIPANTS Patients on maintenance hemodialysis with hyperphosphatemia. METHODS An intensive hyperphosphatemia control education program lasting for 6 months was conducted among 366 hemodialysis patients applying the First Principles of Instruction model, which focused on mastering four stages: (a) activation of prior experience, (b) demonstration of skills, (c) application of skills and (d) integration of these skills into real-world activities. The controlled percentage of serum phosphorus, knowledge of hyperphosphatemia, and adherence to phosphate binders before and after the education program were assessed. RESULTS The proportion of controlled serum phosphorus was significantly increased from 43.5 to 54.9% (P<0.001). The scores on the knowledge of phosphate control were improved significantly from 59.0 ± 18.9 to 80.6 ± 12.4 (P < 0.001). The proportion of high adherence to phosphate binders was increased dramatically from 21.9 to 44.5% (P < 0.001). CONCLUSION The intensive education program can effectively improve serum phosphorus, knowledge of hyperphosphatemia, and adherence to phosphate binders among hemodialysis patients.
