Updated as cultures are reported. The antibiogram refreshes from your own microbiology results, not a spreadsheet compiled once a year.
The basics
What is an antibiogram?
An antibiogram is a summary of how often the bacteria isolated in a hospital are susceptible to each antibiotic. It is usually shown as a table of organisms against antibiotics, with the percentage of isolates that tested susceptible.
Clinicians use the antibiogram to choose empirical therapy, the treatment given before a patient's own culture result is back. Stewardship teams use it to set treatment guidelines and to watch resistance change over time.
Cumulative antibiograms are usually prepared following CLSI guideline M39. For example, it counts only the first isolate of each organism per patient in the period, and reports organisms with at least 30 isolates. Many hospitals still compile theirs once a year by hand, so it can be months old by the time prescribers see it.

What Ibhar does
Your antibiogram, always current. Always at hand.
Hospital and unit views. Resistance differs between the ICU and the wards, so each unit gets its own antibiogram.
CLSI-aligned. Antibiograms and microbiology workflows follow CLSI guidance.
Treatment guidelines kept in step. Empirical therapy guidelines stay in line with the live antibiogram.
MIC guiding tables. Hospital-specific MIC tables help prescribers read susceptibility results.

Choosing a platform
What to look for in antibiogram software.
- Built from your own data. A hospital antibiogram should come straight from your laboratory results, refreshed continuously.
- Follows CLSI rules. First-isolate selection and minimum isolate counts keep percentages meaningful.
- Unit-level views. ICU, ward and specimen-level antibiograms, because one hospital-wide table can hide important differences.
- Reaches the prescriber. An antibiogram helps only if it is in front of the clinician at the moment of prescribing. Ibhar puts it on the phone.
- Linked to stewardship. Treatment guidelines, approvals and time-outs should use the same antibiogram.
- Proven at scale. Ibhar's platform powers VAMR, a national antibiogram and resistance study across 100 hospitals, with WHO as technical partner.
Questions
Answered.
An antibiogram is a summary of how often the bacteria isolated in a hospital are susceptible to each antibiotic, usually shown as the percentage of isolates of each organism that tested susceptible. Clinicians use it to choose empirical therapy before a patient's culture result is available.
It is compiled from the hospital's cumulative culture and susceptibility results, usually following CLSI guideline M39: counting the first isolate of each organism per patient and reporting organisms with enough isolates to be meaningful.
CLSI M39 recommends that cumulative antibiograms are analysed and presented at least once a year. Ibhar keeps hospital and unit antibiograms live, updating them as cultures are reported.
A susceptibility report gives the result for one patient's isolate. An antibiogram summarises many isolates across the hospital or unit, to guide treatment before an individual result is available.
Yes. Ibhar builds hospital-wide and unit-level antibiograms, such as for intensive care units, from the hospital's own microbiology data.
Yes. Ibhar's antibiograms and microbiology workflows follow CLSI guidance.
