ABSTRACT
Objective:
To explore the effects of dietary phosphate restriction education on serum phosphorus level, dietary phosphate intake and the knowledge of hyperphosphatemia in maintenance hemodialysis (MHD) patients.Methods:
This study was a retrospective cohort study. A total of 116 hemodialysis patients in Huashan Hospital, Huadong Hospital and Tongji Hospital from October 2019 to December 2020 were enrolled in this study. They were divided into short-term group (84 cases) and long-term group (32 cases). The short-term group did not receive education or received education≤60 minutes. Meanwhile, the long-term group received education>60 minutes. Serum phosphorus level, dietary phosphate intake and knowledge of hyperphosphatemia were compared between the two groups after 4 weeks.Results:
At baseline, age [64(56, 69) years old vs 65(60, 73) years old, Z=-1.493, P=0.136], the proportion of males [58.3%(49/84) vs 56.3%(18/32), χ2=0.041, P=0.839], dialysis age [55(26, 130) months vs 53(20, 132) months, Z=-0.062, P=0.951], body mass index, diabetes history, single-pool Kt/V, proportion of calctriol used, blood calcium, blood phosphorus, intact parathyroid hormone and dietary protein, dietary phosphorus and dietary phosphorus protein ratio had no statistical significance between short-term group and long-term group (all P>0.05). Adequate dietary phosphate restriction education reduced dietary phosphate intake [777.98(653.81, 943.16) mg/d vs 896.56(801.51, 1 015.51) mg/d, Z=-2.903, P=0.004], phosphate/protein ratio [13.16(11.52, 14.21) mg/g vs 15.27(13.31, 17.48) mg/g, Z=-3.929, P<0.001] and serum phosphorus level [(1.42±0.37) mmol/L vs (1.85±0.44) mmol/L, t=4.984, P<0.001]. Meanwhile, such education significantly improved achievement rate of serum phosphorus (62.5% vs 41.7%, χ2=4.034, P=0.045). In addition, patients in long-term group answered more questions correctly (completely correct plus partially correct) about the causes (93.8% vs 72.6%, χ2=6.120, P=0.013), poor prognosis (78.1% vs 52.4%, χ2=6.372, P=0.012) of hyperphosphatemia as well as the types of food with high phosphate (65.6% vs 52.4%, χ2=1.650, P=0.199).Conclusion:
Adequate dietary phosphate restriction education reduces serum phosphorus level and dietary phosphate intake, and improves the knowledge of hyperphosphatemia in MHD patients.
