Abstract

Introduction: Chronic kidney disease (CKD) is a global public health problem with increasing prevalence and incidence and poor prognosis. As a result, more patients will be in terminal stage kidney failure and require placement of vascular access for hemodialysis. Mature and functional arteriovenous fistula (AVF) is considered the best modality for access to hemodialysis. This study aims to examine the CAVeA2T2 scores in predicting failure of arteriovenous fistula radiocephalic, significant factors related to failure of arteriovenous fistula so that it can be used to predict failure using a scoring system to predict primary failure and secondary failure fistula.

Methods: A cross-sectional study was carried out at Sanglah Hospital, Bali, Indonesia, during the study period. This study using diagnostic test evaluation method using ROC curve analysis on months 1 and 3, a total of 50 populations obtained using Purposive sampling quota period April 2018 - December 2018 and failure of Hemodialysis as gold standard. Data were analyzed using Stata version 12 for Windows.

Results: Results of the CAVeA2T2 score where the maximum score of 7 was analyzed using the ROC curve, the cutoff point was obtained at month 1 ≥5 with AUC 0.8987 and at 3 months ≥ 4 with AUC 0.3966 sensitivity and specificity CAVeA2T2 score of 91.3% and 75% in month 1, in the 3rd month 85.7% and 87.5% were obtained.

Conclusion: Sensitivity and specificity values that provide a good value so that the CAVeA2T2 score can be used to predict failure of arteriovenous radiocephalic fistulas.
