Abstract: Objective To explore the effects of Omaha system on treatment compliance and calcium and phosphorus metabolism in maintenance hemodialysis (MHD) patients. Methods A total of 80 patients were enrolled in this survey. They were divided into intervention group (n=40) and control group (n=40) according to date of the dialysis. The intervention group accepted Omaha system care, while the control group was only provided regular care. The Treatment Compliance Scale scores, daily fluid intake, daily salt intake, subjective global assessment (SGA) scores, serum albumin (Alb), prealbumin (PA), hemoglobin (Hb), triacylglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), Ca and P were compared before and after intervention between the two groups. Results Before intervention, the Treatment Compliance Scale scores, daily fluid intake, daily salt intake, SGA scores, Alb, PA, Hb, TG, TC, LDL, HDL, Ca and P were not significantly different between the two groups (P＞0.05). After the intervention, the intervention group had higher Treatment Compliance Scale scores (t=4.903, P=0.000 for diet compliance; t=2.630, P=0.010 for liquid intake compliance; t=3.491, P=0.001 for medication compliance; t=3.510, P=0.001 for dialysis treatment compliance), and lower daily fluid intake (t=-5.443, P=0.000) and daily salt intake (t=-5.160, P=0.000) as compared with those of control group. Patients in intervention group also had a better nutritional statue (t=-2.615, P=0.011 for SGA; t=2.263, P=0.026 for PA; t=2.047, P=0.044 for Hb) and improved calcium (t=2.183, P=0.032) and phosphorus metabolism (t=2.183, P=0.032), Scr (t=-2.563, P=0.012), BUN (t=-2.277, P=0.025) and Kt/V (t=1.991, P=0.050) than those of control group. Conclusion Omaha system can effectively improve treatment compliance and calcium and phosphorus metabolism in MHD patients, thus deserves further application.
