Abstract:
Background: Contrast media is one of the most common causes of acute kidney failure. We, therefore, want to study the incidence and factors that cause this condition.
Objective: To determine the Incidence of Contrast-Induced Nephropathy (CIN) and associated factors in chronic kidney disease patients at Burapha University Hospital between October 2018 - October 2019.
Method: Retrospective cross-sectional study. The data were collected from program HosXp, PAC, and also from medical records. Statistical calculations were done, using Logistic regression and Multivariate logistic regression analysis.
Result: The incidence of CIN occurs in 23 out of 205 patients, accounting for 11.2%. Factors that increase the risk of CIN included kidney function (GFR) that is less than 15 ml/min/1.73m2, so that the risk of CIN increased to 21.01 times (95% CI: 3.34, 131.97, p = 0.001) compared to GFR in the range of 30 - 59 ml/min/1.73m2, and the amount of contrast media per body weight ≥ 2.5 ml/kg, increased the risk of CIN to 4.8 times (95% CI: 1.12, 20.61, p = 0.035) compared to the group that received the amount of contrast media per body weight <2.5 ml/kg.
Conclusion: In chronic kidney disease patients, kidney function (GFR) that is less than 15 ml/min/1.73m2 and the amount of contrast media per body weight ≥ 2.5 ml/kg increases the risk of CIN.
