An antibiogram is a collection of antimicrobial susceptibility test results from cultures performed over a specific period. A table shows how susceptible a group of organisms is to different antimicrobials. Antiprograms are typically generated for a specific health care facility or health system.

Hospital-Acquired Organism Details

Overall Flow Chart

 

Community-Acquired

Hospital Acquired

Critical Care

Non Critical Care

*Xone sensitive – suspected to most of the cephalosporins

ESBL – resistant to Ceftriaxone (=III gen cephalosporin)

CRE – resistant to Carbapenem (Meropenem)

Hospital Acquired (UTI)

Among the hospital-acquired UTI- only 4 critical cases reported

  • 2 – Candida (Flu sensitive)
  • 1 – E.coli (xone sensitive)
  • 1 – Proteus mirabilis (pan sensitive).

Conclusion

Majority were related to UTI

Enterobacterale especially E.coli and Klebsiella were dominating followed by candida.
