چکیده مقاله:

Background and Objectives: Nowadays, catheter related bloodstream infections are considered as one of the serious problems of the health system. In addition to many complications, they impose many economic burdens on the health system. They also increase the odds of death in patients. The objective of this study was to investigate the prevalence of these infections in ICUs of Namazi hospital, as the largest hospital in the south of Iran. Materials and Methods: This study was conducted in the ICU units of Shiraz Namazi Hospital during a 12 month period (April 2015 to April 2016). A total of 178 patients were included into study and 253 catheters inserted in them were examined. Results: out of 253 catheters, 47.4% had positive culture (120 catheters) and 52.6% had negative culture (133 catheters). The most common microorganisms causing catheter related bloodstream infections were gram negative bacteria (50%). Among the gram-negative bacteria, Acinetobacter (51.7%) and Klebsiella (25%), and among the grampositive bacteria, Staphylococcus epidermidis (66.7%) and Enterococcus (Streptococcus group D) (23%) were the most common causes of infection. Colistin (90% sensitivity) and amikacin (33.3sensitivity) were the most effective antibiotics in gram-negative bacteria and chloramphenicol (87.5%) and vancomycin (75%) were the most effective in gram-positive bacteria. Conclusion: this study revealed that the prevalence of catheter related bloodstream infections was 47.4% in the patients hospitalized in ICUs of Namazi Hospital. Therefore, the odds of having a catheter related bloodstream infection is higher in such patients than in others. In addition to increasing the rate of death, it imposes high costs on the patient and the hospital. In this study, it was also found that increasing the duration of hospitalization in ICUs increased the odds of catheter related bloodstream infections. In this study, the most antibiotic sensitivity among gram-negative bacteria was colistin (90%) and the most antibiotic sensitivity among gram-positive bacteria was chloramphenicol (87.5%) and vancomycin (75%), and all isolated bacteria, either grampositive or gram-negative, were resistant to meropenem, ampicillin, azithromycin, ofloxacin, piperacillin, ceftriaxone, ceftazidime, amoxicillin, oxacillin, and rifampin.
