Abstract
Background
A not optimal way of the insertion of the intravenous catheter can be one of the factors that cause bloodstream infection (BSI) that should be confirmed with blood culture, and if positive it is called Laboratory-Confirmed Bloodstream Infection (LCBI). One of the surveillance methods of nosocomial infection that is commonly used is the Multi Antibiotic Resistance (MAR)-Index. The aimed of study was association of MAR-index from blood isolates on LCBI category.
Method
This study used a cross-sectional study with a consecutive sampling method. Data collection for this study includes identification of micromaterial profile, antimicrobial test, MAR-Index, and LCBI category. The analysis used is the Mann Whitney test with p < 0.05.
Result
There were 43 isolates of LCBI 1, 26 isolates of LCBI 2, and none of the LCBI 3. Microorganisms in the LCBI category 1 were Staphylococcus aureus (53.4%), Acinetobacter baumannii (20.9%), Escherichia coli (9.3%), Klebsiella pneumonia (7.0%), Pseudomonas aeruginosa (4.7%), and Enterococcus faecalis (4.7%) with the MAR-Index ranged from 0.22 to 0.91. Microorganisms in the LCBI category 2 were Staphylococcus haemolyticus (69.3%), Staphylococcus epidermidis (19.3%), Staphylococcus hominis (3.8%), Streptococcus viridans (3.8%), and Corynebacterium jeikeium (3.8%) with the MAR-Index ranging between 0.11 and 0.79. There is no significant difference of MAR-index between LCBI 1 and 2 (p = 0.424) and no association of MAR-index on LCBI (p = 0.571).
Conclusion
Most LCBI type 1 is Staphylococcus aureus and LCBI type 2 is Staphylococcus haemolyticus which there is no significant association of MAR-index on LCBIs.
No significant comparison of MAR-index values in LCBI types 1 and 2.
The most common type 1 LCBI found was Staphylococcus aureus.
The most common type 2 LCBI found was Staphylococcus haemolyticus.
