Abstract: Objective  To explore the application effect of a diet management software for peritoneal dialysis (PD) patients at home.  Methods   Patients regularly followed up in the Peritoneal Dialysis Center, The First Affiliated Hospital, Naval Medical University between July and December 2020 were recruited as the research subjects. They were divided into experimental group (n=35) and control group (n=35) by random number method. The control group received routine follow-up management, and the experimental group used the dietary management software. They were followed up for 3 months. Serum albumin and potassium, and blood phosphorus were compared between the two groups.  Results  Compared to the control group, serum albumin was higher (t=2.101, P=0.040) and serum phosphorus was lower (t=-2.054, P=0.044) in the experimental group after the intervention for 3 months. In the experimental group, serum albumin became higher (t=3.226, P=0.002) and serum phosphorus became lower (t=2.007, P=0.049) after the intervention for 3 months. The prevalence of abnormal serum potassium in the follow-up period was lower in the experimental group (χ2=3.913, P=0.048).  Conclusion  The dietary management software can help PD patients have rational dietary, improve serum albumin and blood phosphorus, and reduce the incidence of abnormal blood potassium.
