Abstract: 【Abstract】Objective To explore the effect of strength model of case management (SMCM) on nutritional inflammatory state and residual renal function (RRF) in peritoneal dialysis (PD) patients. Methods A randomized digital table method was used to select 110 PD patients in the PD Center of The First Affiliated Hospital of Guangxi Medical University. They were randomly divided into control group (n=55) and intervention group (n=55). Routine care was used for both groups, and SMCM for 6 months on the basis of routine care was performed for intervention group. Nutritional inflammatory state related body measurements, biochemical indicators and residual renal function were compared after the intervention between the two groups. Results In intervention group after the intervention, malnutrition- inflammation (MIS) scores (t=6.672, P＜0.001), mid-upper arm circumference (MAC, t=-2.949, P=0.004), triceps skin fold (TSF, t=-2.002, P=0.048), pre-albumin (PA, t=-2.072, P=0.041) and high sensitive C-reactive protein (hs-CRP, t=6.064, P＜0.001) improved significantly. Conclusion SMCM for PD patients can significantly improve their malnutrition and inflammatory state. However, SMCM changed RRF insignificantly.
