Table HKW-1. Antibiogram for all isolates, HKW, 2015

  1. Non-duplicate isolates from blood, urine and respiratory specimens. Interpreted according to CLSI. Nonsusceptible include both intermediate & resistant.
  2. Results for Enterobacteriaceae were interpreted according to CLSI M100-S20.
  3. HoPL Int J Antimicrob Agents 2010;36:469 and J Hosp Infect 2010;74:358
  4. Overall prevalance of extended-spectrum beta-lactamases (ESBL) were 22% for Klebsiella species, 30% for E. coli. ESBL-producing strains should be interpreted as resistant to all penicillins, cephalosporins and aztreonam.
  5. In S. pneumoniae, resistance to azrithromycin & clarithromycin can be predicted by testing erythromycin (CLSI M100-S20).
  6. Most had other risk factor such as past hospitalization and nursing home residence.
  7. Test performed on non-urine isolates only.
  8. HoPL J Antimicrob Chemo 2009;63:836
  9. According to breakpoint for parenteral cefuroxime sodium.
  10. Urine isolates only.
  11. , indicate 10% or more reduction in resistance rate compared to 2014.
    , indicate ≥10% increase in resistance rate compared to 2014.

* Including MIC ≤ 0.06 (43.8%), MIC 0.09-1 (23.1%), MIC 1.5-2 (24.8%), MIC 3-6 (8.3%)
* %Penicllin sensitive: meningitis breakpoint at MIC ≤0.06 = 43.8% and non-meningitis breakpoint at MIC≤2 = 91.7%
