[Abstract]
OBJECTIVES: To determine the incidence of bacteremia in patients with DKA.

METHODS: We conducted a cross-sectional study of patients aged 18 years and older with a principal diagnosis of DKA or hyperglycemic hyperosmotic syndrome (HHS) who presented to our community hospital between 2008 and 2020. Using medical records from initial visits, we retrospectively calculated the incidence of bacteremia. This was defined as the percentage of subjects with positive blood cultures except for those with contamination.

RESULTS: Among 114 patients with hyperglycemic emergency, two sets of blood cultures were collected in 45 of 83 patients with DKA (54%), and 22 of 31 patients with HHS (71%). The mean age of patients with DKA was 53.7 years (19.1) and 47% were male, while the mean age of patients with HHS was 71.9 years (14.9) and 65% were male. The incidences of bacteremia and blood culture positivity were not significantly different between patients with DKA and those with HHS (4.8% vs. 12.9%, P = 0.21 and 8.9% vs. 18.2%, P = 0.42, respectively). Urinary tract infection was the most common concomitant infection of bacteria, with E. coli as the main causative organism.

CONCLUSION: Blood cultures were collected in approximately half of the patients with DKA, despite a nonnegligible number of them testing positive in blood culture. Promoting awareness of the need for taking blood culture is imperative for the early detection and management of bacteremia in patients with DKA.
