Abstract

Despite concerns about its nephrotoxicity, colistin often remains the only effective agent for treating multidrug-resistant Gram-negative infections. Published studies have reported a wide range of nephrotoxicity risk factors. To assess the clinical utility of various models, we compared their performances for predicting the risk of nephrotoxicity. We identified a model demonstrating reasonable overall risk assessment, with an observed/expected ratio of 1.29 (95% confidence interval [CI], 0.68 to 1.90) and a positive predictive value of 87.5% for identifying patients at high risk of developing nephrotoxicity.

摘要

尽管人们担心黏菌素具有肾毒性,但它通常仍是治疗多重耐药革兰氏阴性菌感染的唯一有效药物。已发表的研究报告了多种肾毒性风险因素。为评估各种模型的临床实用性,我们比较了它们预测肾毒性风险的表现。我们确定了一个显示出合理总体风险评估的模型,其观察值与预期值之比为1.29(95%置信区间[CI],0.68至1.90),识别发生肾毒性高风险患者的阳性预测值为87.5%。
