Catheter-associated bloodstream infections (CABSI) in hemodialysis patients are often caused by Gram-negative bacteria like Pseudomonas aeruginosa and MRSA. Prolonged catheter use and femoral insertion are key modifiable risk factors.
Area of Science:
- Nephrology
- Infectious Diseases
- Public Health
Background:
- Catheter-associated bloodstream infections (CABSI) pose a significant clinical and financial burden in nephrology.
- Hemodialysis (HD) patients are particularly vulnerable to CABSI due to central venous catheter use.
Purpose of the Study:
- To identify clinical risk factors for CABSI in HD patients.
- To determine the prevalence of causative bacterial pathogens in CABSI among HD patients in Pakistan.
Main Methods:
- A cross-sectional study involving 150 HD patients with CABSI at CMH Hospital, Multan.
- Data collected included clinical details and dual blood samples for culture.
- Analysis focused on identifying risk factors and prevalent pathogens.
Main Results:
- Gram-negative bacteria (55.33%) were more prevalent than Gram-positive bacteria (44.66%).
- Key pathogens identified were Pseudomonas aeruginosa (18.00%) and MRSA (16.67%).
- Modifiable risk factors included prolonged catheter use (>30 days), femoral site insertion, comorbidities, and anemia.
Conclusions:
- Prolonged catheter use and femoral insertion are significant modifiable risk factors for CABSI in HD patients.
- Targeted antimicrobial strategies and early arteriovenous fistula creation are recommended, especially in resource-limited settings.
