Análisis de las hospitalizaciones por bacteriemia relacionada con el catéter de hemodiálisis

Abstract

The use of central venous catheters for haemodialysis has increased to such an extent that in our country 30% of patients now have this vascular access. However their duration is limited and they frequently present complications, such as bacteraemia related to the haemodialysis catheter. This is a complication with high morbimortality in patients undergoing chronic renal replacement therapy.The aim of this analysis was to determine the incidence of hospitalizations, identify the germs most frequently found in our population and analyse the associated demographic and clinical factors. A prospective observational study was carried out in which all hospital admissions during 2011 for bacteraemia related to the haemodialysis catheter were analysed. Clinical, demographic and comborbility data of the patients were compiled. The total number of admissions for catheter-related bacteraemia was 45 in 35 patients, with a mean age of 69.9 years. The most frequently isolated germs were grampositive cocci (Methicillin-Resistant Staphylococcus Aureus and Methicillin-Sensitive Staphylococcus Aureus). Mortality was 14% (5 pa-tients). In light of our results, we may conclude that catheter-related bacteraemia is a serious complication in haemodialysis patients. It represents almost 50% of hospital admissions in 2011 of haemodialysis patients. It is associated to high morbility and consumption of resources.
