Objective:To evaluate the value of the geriatric depression inventory(GDI)in screening depressive disorder in elderly patients with heart failure,and to determine the optimal cut-off point.Methods:A total of 195 elderly patients with heart failure were selected using the convenient sampling method from three general hospitals in Beijing from September 2017 to December 2018 to receive GDI assessment.The Chinese version of the mini-international neuropsychiatric interview(M.I.N.I.)was used as the gold standard.Results:According to the M.I.N.I.results,the subjects were divided into two groups,group with depressive disorder(90 patients,including 52 major depressive disorder,30 minor depressive disorder and 8 dysthymia)and group without depressive disorder(105 patients).The area under the ROC curve of GDI was 0.98(SE=0.01,95％CI:0.97-1.00,P＜0.01).The best cut-off point was 5 points,with a sensitivity of 93.3％,a specificity of 93.3％,a positive predictive value of 94.5％,and a negative predictive value of 94.2％.Conclusions:GDI has a high screening value for depressive disorder in elderly patients with heart failure,and it is worth promoting in this population.The best cut-off value is 5 points.
