Burkholderia spp. are opportunistic pathogens that cause infection in patients with disrupted immunity. The study intended to demonstrate the epidemiology and clinical features associated with Burkholderia spp. bacteremia. This retrospective study was performed to assess the clinical and laboratory characteristics of patients whose blood cultures were growing Burkholderia spp. and, based on their underlying comorbidities, were subjected to survival analysis from January 2022 to December 2022 at a university hospital in northern India. Three hundred patients with Burkholderia spp. bacteremia were included in this study conducted over 1 year. The mean age of the patients was 33.86 years with a male predominance of 56.67% (170/300, 56.67%). Underlying malignancies (207/300, 69.0%) were the most common clinical diagnosis, and catheter in situ (300/300, 100.0%) was the most common risk factor. Burkholderia cenocepacia (244/300, 81.33%) was the most common Burkholderia spp. isolated. All isolates were highly susceptible to minocycline. Kidney disease (P = 0.029), hypertension (P = 0.005), type 2 diabetes mellitus (P = 0.039), and respiratory disease (P <0.001) in patients were significantly associated with death owing to Burkholderia spp. bacteremia, whereas patients with malignancies (P <0.001) and undergoing treatment were significantly associated with a better outcome when the microorganism was susceptible to empirical antibiotics. The presence of indwelling devices, mechanical ventilation (P <0.001), and a hemodialysis catheter (P = 0.026) were statistically significant risk factors associated with poor outcomes.
