Methods:A total of 2,000 cancer patients were consecutively screened using the Nutritional Risk Screening 2002 instrument on ad-mission.Patients at nutritional risk(Nutritional Risk Screening 2002 score≥3)were enrolled to obtain the complete GLIM,PG-SGA,and mPG-SGA criteria.To evaluate the convergent validity,Spearman correlation analysis was used to compare the test-retest reliability of the GLIM criteria and its results with the scores of various nutritional tools and objective parameters.Kruskal-Wallis tests and χ2 tests were used to test the discriminant validity among groups with different nutritional status.We calculated the sensitivity,specificity,positive predictive value,and negative predictive value for the various tools. Results:There were 562 patients found to be at nutritional risk,accounting for 28.1%of all patients.One hundred seventy-four patients(8.7%)were diagnosed as moderately malnourished,and 333 patients(16.6%)were severely malnourished based on the PG-SGA.When assessed using the GLIM criteria,185 patients(9.3%)were diagnosed as moderately malnourished and 311 patients(15.5%)were severely malnourished.The content validity of the GLIM criteria was 95%,evaluated by 60 medical staff members.The test-retest reliability was good.For the diagnosis of malnutrition versus the PG-SGA,the sensitivity of the GLIM was"good"(90.5%;95%confidence interval[95%CI]=88.0%-93.1%),with a positive predictive value of 92.5%(95%CI=90.2%-94.9%),but the spec-ificity and negative predictive value were"poor."Similar results were obtained when the mPG-SGA was used as the criterion.

文摘Objective To explore the consistency of the Patient-generated Subjective Global Assessment(PG-SGA)and Nutritional Risk Screening-2002(NRS-2002)for nutritional evaluation of patients with gynecologic malignancy and their predictive effect on the length of hospital stay(LOS).Methods We recruited 147 hospitalized patients with gynecologic malignancy from Nanfang Hospital in 2017.Their nutritional status was assessed using the PG-SGA and NRS-2002.The consistency between the two assessments was compared via the Kappa test.The relationship between malnutrition and LOS was analyzed using crosstabs and Spearman’s correlation.Results The PG-SGA demonstrated that 66.7%and 54.4%of patients scoring≥2 and≥4 were malnourished,respectively.Furthermore,the NRS-2002 indicated that 55.8%of patients were at nutritional risk.Patients with ovarian cancer had a relatively high incidence of malnutrition.However,this was only significant for patients who scored≥4 in the PG-SGA(P=0.001 and P=0.019 for endometrial carcinoma and cervical cancer,respectively).The PG-SGA and NRS-2002 showed good consistency in evaluating the nutritional status of patients with gynecologic malignancy(0.689,0.643 for PG-SGA score≥2,score≥4 and NRS-2002,respectively).Both the scores of PG-SGA and NRS-2002 were positively correlated with LOS.Furthermore,prolonged LOS was higher in patients with malnutrition than in those with adequate nutrition.Conclusion The PG-SGA and NRS-2002 shared a good consistency in evaluating the nutritional status of patients with gynecologic malignancy.Both assessments could be used as predictors of LOS.
