Figures & data

Table 1 Univariate Analysis of Risk Factors for Carbapenem-Resistant Klebsiella pneumoniae Bloodstream Infections

Figure 1 Admission diagnoses among patients with Klebsiella pneumoniae bloodstream infections. Infectious diseases and digestive diseases were the major admission diagnoses among patients with Klebsiella pneumoniae bloodstream infections. “Others” includes an assortment of admission diagnoses that were grouped because the frequencies of the individual diagnoses were too small to display separately.

Figure 2 Frequency distribution of hospital departments among patients with Klebsiella pneumoniae bloodstream infections. Intensive care units and general surgery were the most common departments among patients with Klebsiella pneumoniae bloodstream infections. “Others” includes an assortment of departments that were grouped because the numbers of patients admitted to each department were too small to display separately.

Figure 3 Survival curves comparing survival among patients with carbapenem-resistant and non- carbapenem-resistant Klebsiella pneumoniae bloodstream infections. Patients with carbapenem-resistant Klebsiella pneumoniae bloodstream infections had a lower survival than patients with non-carbapenem-resistant K. pneumoniae bloodstream infections (P<0.001).
