IBANEZ FRANCO, Elvis Javier et al. Risk factors associated with hemodialysis catheter infection in a referral center. Rev. virtual Soc. Parag. Med. Int. [online]. 2022, vol.9, n.1, pp.23-33. ISSN 2312-3893.


Hemodialysis catheter-associated infection is an important cause of morbidity and mortality in patients who require permanent hemodialysis, raising the risk of mortality two times more than those who do not. For this reason, it is essential to determine the predisposing factors to acquire this infection.


To determine the risk factors associated with hemodialysis catheter infection in patients at the Hospital Nacional of Itauguá.


An observational case-control study of 104 patients was carried out, 52 patients as cases and 52 as controls.


The following qualitative variables were analyzed as risk factors: lack of knowledge of catheter care (OR: 9.66; p: <0.05), absence of fixed three-week shift (OR: 3.70; p: <0. 05), diabetes mellitus (OR: 1; p: >0.05), arterial hypertension (OR: 1.17; p: >0.05), absence of previous infection (OR: 2.25; p: <0, 05), rural origin (OR: 2.67; p: <0.05), femoral catheter location (OR: 6.51; p: <0.05), colonization with Staphylococcus aureus (OR: 15.6; p: <0.05), single weekly cure (OR: 37.40; p: <0.05) and primary education (OR: 2.93; p: <0.05). Regarding the quantitative variables, age (p: <0.05), time of catheter installation (p: <0.05) and time of evolution of hemodialysis (p: 0,2) were analyzed.


Ignorance of catheter care, absence of three-week fixed shift, rural origin, colonization with Staphylococcus aureus, catheter healing once a week, primary education, age over 51 years and recent catheter installation were significantly associated with hemodialysis catheter infection.
