Summary
Acquired bloodstream infections (bacteraemias) in the intensive care unit (ICU) are serious. Flavobacterium spp. and Pseudomonas aeruginosa were common, with resistance to some antibiotics, impacting patient outcomes.
Area of Science:
- Infectious Diseases
- Critical Care Medicine
- Microbiology
Context:
- Acquired bloodstream infections (bacteraemias) in intensive care units (ICUs) pose significant risks.
- The rise of multidrug-resistant organisms complicates treatment and worsens patient prognosis.
- Understanding local epidemiology and germ sensitivity is crucial for effective management.
Purpose:
- To investigate the epidemiological patterns of acquired bacteraemias in an ICU.
- To determine the antimicrobial sensitivity of causative microorganisms.
- To inform strategies for appropriate antimicrobial therapy.
Summary:
- A study of 31 bacteraemias in 19 ICU patients revealed an incidence of 6.3 per 100 admissions.
- Flavobacterium spp. (42%) and Pseudomonas aeruginosa (26.2%) were the most frequent pathogens.
- While most Gram-negative bacteria showed sensitivity to certain antibiotics, coagulase-negative Staphylococci were methicillin-resistant.
Impact:
- The overall mortality rate was 42%, with 15.3% directly attributed to bacteraemia.
- Effective antimicrobial treatment was administered in 84.2% of cases.
- Strengthening nosocomial infection control committees is vital for reducing morbidity and mortality from ICU infections.
