Abstract
Background: Bacterial blood stream infection constitutes a significant public health problem and it is an important cause of morbidity and mortality in hospitalized patients. The aim of this study was to determine the characteristics of bloodstream
infections in patients who hospitalized in Namazi hospital, a teaching hospital in Shiraz, Iran.
Methods: This is a prospective observational cohort study of patients with bloodstream infections. Bloodstream infection was defined as hospital-acquired if the first positive blood culture was performed more than 48 h after admission. Other bloodstream
infections were classified as healthcare-associated or communityacquired. The samples were collected and processed following standard microbiological techniques as part of the routine clinical management of the patient. Data were analyzed by using SPSS version 16.
Results: A total of 303 episodes of bloodstream infections were studied; 119 (39.3%) were community-acquired, 108 (35.6%) were hospital-acquired, and 76 (25.1%) were healthcareassociated. Renal failure was more common in patients with healthcare-associated or hospital-acquired bloodstream infection than in patients with community-acquired bloodstream infection. Hospitalization in intensive care unit (ICU) was the most common source of hospital-acquired and urinary catheters were the most common source of healthcare-associated and communityacquired. The most frequent bacteria isolated from blood culture were Coagulase negative staphylococci (31.7%) that frequency of this gram positive bacteria was 24.3% in community-acquired, 22.3 in healthcare-associated and 46.3 in hospital-acquired bloodstream infection.
Conclusion: Healthcare-associated bloodstream infections are similar to hospital-acquired in terms of frequency of various comorbid conditions and pathogens. More study with higher sample number and antibacterial susceptibility recommended.
