ARTICLE HIGHLIGHTS

Research background

Secondary hyperparathyroidism, renal osteodystrophy, and cardiovascular adverse events can occur if long-term hyperphosphatemia is not corrected, leading to the adverse prognosis of patients with chronic renal failure. The clinical control measures for hyperphosphatemia in these patients include diet control.

Research motivation

Provide reference for the treatment of patients with chronic renal failure and hyperphosphatemia.

Research objectives

This study aimed to observe doctor-led intensive diet education effects on health-related quality of life, in patients with chronic renal failure and hyperphosphatemia.

Research methods

We assessed 120 patients with chronic renal failure hemodialysis and hyperphosphatemia admitted to our hospital (July 2018–March 2020). The levels of serum parathyroid hormone (iPTH), calcium (Ca), phosphorus (P), calcium-phosphorus product (Ca × P), serum creatinine (Scr), and blood urea nitrogen (BUN) before intervention and 3 and 6 mo after intervention in the groups were assessed.

Research results

After 3 mo and 6 mo of intervention, the blood iPTH, Ca, P and Ca × P in the two groups decreased gradually, but there was no significant difference in Scr and BUN. The blood iPTH, Ca, P and Ca × P in the observation group were lower than those in the control group. The overall EQ-5D-3L score of the observation group was better than that of the control group. The scores of disease-related knowledge and compliance were higher in the observation group than in the control group.

Research conclusions

Doctor-led intensive diet education can improve the quality of life of patients with chronic renal failure and hyperphosphatemia, promote low-phosphorus diet behavior, and improve patient satisfaction.

Research perspectives

Exploring treatment approaches for patients with chronic renal failure and hyperphosphatemia can provide references for clinical work in the future.
