We evaluated clinical factors associated with early central venous catheter (CVC) removal in cancer patients with candidaemia who survived >3 days after the index blood culture. This was a retrospective cohort study from a previous candidaemia database conducted between January 2001 and June 2005. Eligible patients were those whose catheters were removed. Those who died in the first 72 h were excluded. Early CVC removal was defined as withdrawal in the first 72 h. We enrolled 164 patients with a 10.4% mortality rate. Multivariate analysis showed temporary non-tunnelled catheter type (odds ratio 5.06; 95% confidence interval 2.16-11.83) as the only variable associated with early removal. Among the 84 episodes judged not catheter-related, 52 CVCs were removed due to the need for further cancer treatment. No differences in mortality were seen among patients with early or late catheter removal. Stratified analysis showed a survival benefit (p = 0.04) of early removal among patients with a Karnofsky performance status score >60. The study shows a propensity to immediately remove short-term catheters and a tendency for early removal in patients undergoing active cancer treatment. There was no benefit of early catheter removal with regard to overall mortality. The favourable impact of early over late removal on survival among patients without significant illness merits further investigation.
我们评估了在首次血培养后存活超过3天的念珠菌血症癌症患者中,与早期拔除中心静脉导管(CVC)相关的临床因素。这是一项基于2001年1月至2005年6月期间建立的念珠菌血症数据库的回顾性队列研究。符合条件的患者是那些导管被拔除的患者。排除在最初72小时内死亡的患者。早期CVC拔除定义为在最初72小时内拔除。我们纳入了164例患者,死亡率为10.4%。多变量分析显示,临时非隧道式导管类型(比值比5.06;95%置信区间2.16 - 11.83)是与早期拔除相关的唯一变量。在84例判定与导管无关的病例中,52根CVC因需要进一步的癌症治疗而被拔除。早期或晚期拔除导管的患者之间死亡率无差异。分层分析显示,卡诺夫斯基功能状态评分>60的患者中,早期拔除有生存获益(p = 0.04)。该研究表明,对于短期导管有立即拔除的倾向,且正在接受积极癌症治疗的患者有早期拔除的趋势。早期拔除导管对总体死亡率没有益处。早期拔除相对于晚期拔除对无严重疾病患者生存的有利影响值得进一步研究。
