Abstract
Background and aim: Blood culture is one of the methods of diagnosis of bacterial etiology of sepsis, but because of the low number of organisms in the blood or the use of antibiotics, separation of the organism causing sepsis is difficult in this way. This study was designed to determine the predictive factors for positive blood culture in sepsis patients.
Methods: The present historical cohort study was conducted on 320 patients with sepsis who were admitted to Shahid Beheshti Hospital in Kashan from October 2013 to October 2014. By examining patients' records, demographic, clinical and laboratory information including age, sex, hospitalization, temperature, pressure drop, tachycardia, tachypnea, serum CRP (CRP), white blood cell count (WBC), red blood cell sedimentation rate) ESR) and treatment outcomes. Data were analyzed using Chi-square, Mann-Whitney and t-test.
Results: The mean age of patients in the case group was 67.93 ± 12.12 years in the case group (case group) and 64.67 ± 13.87 in the negative control group (control group). Frequency of underlying disease, recent history of admission, hypotension and tachypnea in case group were more than control group. The results of logistic regression analysis indicated that serum reactive protein level, red blood cell dysplasia and white blood cell count are related to the outcome of blood culture in patients with sepsis.
Conclusion: Regarding the relationship between positive blood culture and inflammatory markers, in patients with sepsis, the increased inflammatory markers can be indicative of bacteremia and accelerate the onset of antibiotics and more precision in conducting blood cultures to discover the organism of sepsis.
