Catheter related infections (CRI) and bloodstream infection (BSI) associated to central venous catheter (CVC) is cause of frequent hospital-acquired infection (HAI) and a major reason of morbidity and mortality among patients and it is itself an indicator of quality health care.
To determine the incidence of CRI and BSI and to identify the hospital areas where they occurred over a five-year period.
A prospective study from 2004 to 2008 in a population of hospitalized patients who required the use of CVC was made. The HAI team detected the appearance of CRI during a daily routine surveillance.
During the period of observation, 176 BSI were detected, accounting for 11 % of all HAI, and represented the third place in frequency. Incidence rate for 1000 catheter-days varied from 2.7 in 2006 to 5.4 in 2008; 57 % of these BSI were detected in the intensive care units. Candida spp. accounted as the more frequently isolated microorganism with predominance of C. parapsilosis.
Our results and the incidence rate found in our study occurred within rates established in other studies.
与中心静脉导管（CVC）相关的导管相关感染（CRI）和血流感染（BSI）是医院获得性感染（HAI）的常见原因，也是患者发病和死亡的主要原因，其本身也是医疗质量的一个指标。
确定CRI和BSI的发生率，并确定在五年期间它们发生的医院区域。
对2004年至2008年期间需要使用CVC的住院患者群体进行了一项前瞻性研究。HAI团队在日常监测中检测CRI的出现情况。
在观察期间，共检测到176例BSI，占所有HAI的11%，在感染频率中位居第三。每1000导管日的发生率从2006年的2.7例到2008年的5.4例不等；其中57%的BSI在重症监护病房被检测到。念珠菌属是最常分离出的微生物，以近平滑念珠菌为主。
我们的研究结果及所发现的发生率与其他研究确定的发生率相符。
