Management and outcomes of Burkholderia cepacia complex bacteremia in patients without cystic fibrosis: a retrospective observational study

The objective was to evaluate the management and outcomes of BCC bacteremia in patients without CF. We conducted a retrospective study of non-CF adult patients with BCC bacteremia between January 1997 and December 2016 at 4 tertiary hospitals in South Korea. A total of 216 non-CF patients with BCC bacteremia were identified. Most cases were hospital-acquired (79.2%), and the most common source was a central venous catheter (CVC) (42.1%). The rates of susceptibility to trimethoprim-sulfamethoxazole and piperacillin-tazobactam of BCC isolates were high as 92.8% and 90.3%, respectively. The rates of susceptibility to ceftazidime, meropenem, and levofloxacin were 75.5%, 72.3%, and 64.1%, respectively. The 14-day, 30-day, and in-hospital mortality rate was 19.4%, 23.1%, and 31.0%, respectively. Female (OR  = 3.1; 95% CI, 1.4–6.8), liver cirrhosis (OR = 6.2; 95% CI, 1.6–16.6), septic shock (OR = 11.2; 95% CI, 5.1–24.8), and catheter-related infection (OR = 2.6, 95% CI, 1.2–5.8) were the independent risk factors for 30-day mortality. The outcome did not differ according to type of antibiotics used. Among 91 patients with CVC-related BCC bacteremia, delayed CVC removal (>  3 days) had a higher rate of persistent bacteremia (54.5 vs. 26.1%;P = 0.03) and lower rate of clinical response (49.0 vs. 71.9%;P = 0.04), compared with early CVC removal (within 3 days). BCC bacteremia occurring in non-CF patients was mostly hospital-acquired and CVC-related...
