Factors associated with bacteremia in patients with chronic hemodialysis in Huancayo, Peru

Abstract

Background: Bacteremia in patients on chronic hemodialysis using a central venous catheter represents a high morbidity and mortality in patients with chronic kidney disease. Purpose: Identify the associated factors such as sociodemographic characteristics, comorbidities, and clinical characteristics of bacteremia in hemodialysis and identify the main microorganisms in the Ramiro Priale Priale Hospital, Huancayo from January 2020-March 2023. Methodology: An observational, retrospective case-control study of 60 patients was carried out. 25 cases and 35 controls were acquired. Results: 60 patients were studied. The population was mainly male with 58.3 % (n=56) cases. Most of the patients came from Huancayo 31 % (n=19). 93.3 % of the patients presented arterial hypertension (AHT), and 38.3 % had type 2 diabetes mellitus (DM2). Among the comorbidities, the most frequent was heart disease with 30 % (n=18) of the cases. The main germs found were Staphylococcus Aureus (24 %) and Staphylococcus epidermidis (24 %). A significant association was found between the presence of type 2 diabetes mellitus (OR=5.65) (95 % CI 1.23-10.98) and the presence of comorbidity (OR=13.026) (95 % CI 2.2-15.4) with the presence of bacteremia (p <0.05). Conclusions: Diabetes mellitus and the presence of comorbidities are associated with the presence of bacteremia in patients on chronic hemodialysis.
