Objective To investigate the predictive value of the controlling nutrition status (CONUT) score for the prognosis of peritoneal dialysis-associated peritonitis (PDAP) after treatment. Method A total of 161 patients with PDAP were divided into a cured group and a treatment failure group base on their treatment effect. Their clinical data were compared. Logistic regression was used to analyze the correlation between CONUT score and treatment effect. ROC curve was used to analyze the predictive value of CONUT score on prognosis of the patients after treatment. Result Dialysis age (Z=-3.027, P=0.002), hs-CRP (Z=-2.608, P=009) and CONUT score (Z=-3.161, P=0.002) were higher and albumin (t=2.158, P=0.032) was lower in the treatment failure group as compare with those in the cured group. Univariate logistic regression showed that dialysis age (OR=1.025, 95% CI: 1.011～1.039, P=0.001), hs-CRP (OR=1.006, 95% CI:1.000～1.011, P=0.038), albumin (OR=0.906, 95% CI: 0.827～0.933, P=0.035) and CONUT score (OR=1.529, 95% CI: 1.150～2.039, P=0.004) were the risk factors for poor prognosis of PDAP. Multivariate logistic regression showed that dialysis age (OR=1.024, 95% CI: 1.008～1.039, P=0.002) and CONUT score (OR=1.613, 95% CI:1.058～2.459, P=0.026) were the independent risk factors for poor prognosis of PDAP. ROC curve showed that dialysis age (months) combined with CONUT score had the greatest predictive value for the prognosis of PDAP, and the area under the curve was 0.802 (95% CI: 0.682～0.921, P<0.001). Conclusion Longer dialysis age (months) and higher CONUT score are the independent risk factors for poor prognosis of PDAP. Dialysis age (months) combined with CONUT score is highly predictive for the prognosis of PDAP patients after treatment.
