Antimicrobial monitoring software for hospitals compared by what it monitors, antibiotic use or resistance
Antimicrobial monitoring software means two different products: tools that track antibiotic use and report it to NHSN, and tools that track resistance in your own lab data. Here is which vendors do which, what they cost, and how a hospital should split the budget.

Antimicrobial monitoring software is any system a hospital uses to track how antibiotics are used and how resistant its organisms are. In practice it splits into two products: use monitoring (days of therapy, NHSN AUR submission, real-time pharmacist alerts) and resistance monitoring (the antibiogram, MDRO counts, quarterly trends). Most vendors sell the first. Fewer do the second well, and the price gap between them is large.
This is written for the stewardship pharmacist, pharmacy director or infection prevention lead who has "antimicrobial monitoring" on a budget line or an RFP and has to decide what to buy. Every vendor is described from its own published material, and our own product is named where it fits and where it does not.
Antimicrobial use monitoring and resistance monitoring are different purchases
Use monitoring reads the medication administration record and the admission feed. It counts days of therapy per 1,000 patient days present, compares your use with the NHSN Standardized Antimicrobial Administration Ratio, and fires alerts when a patient is on a drug that needs a pharmacist: a bug-drug mismatch, an IV that could go oral, a restricted agent without approval. It needs live EHR interfaces, so it comes with an implementation project.
Resistance monitoring reads the microbiology results. It answers what share of your E. coli urine isolates are still susceptible to ceftriaxone, whether carbapenem-resistant Enterobacterales are rising on one unit, and what the empiric choice for a given syndrome should be. It needs final susceptibility results and the CLSI M39 rules, and it can run from a file export rather than an interface.
The two halves meet in the CDC Core Elements, which ask hospitals to track both antibiotic use and resistance. They rarely meet in one affordable product. Knowing which half you are short on decides almost everything else.
Antimicrobial monitoring software options side by side
The three largest platforms are compared in detail in Sentri7 vs TheraDoc vs VigiLanz, and the VigiLanz tiers, including what Starter leaves out, are on VigiLanz alternatives.
| Product | Monitors use | Monitors resistance | NHSN AUR | Price published |
|---|---|---|---|---|
| Wolters Kluwer Sentri7 | Yes, with real-time alerts and SAAR | Antibiogram described as produced in seconds | Yes, one-click AUR | No, demo form |
| Inovalon VigiLanz | Yes, alerts and worklists from the base tier | Proportion susceptible on Starter, trending antibiograms on Pro | Yes, from the Starter tier | No |
| Premier TheraDoc | Yes, real-time alerts | Not on the current product page | Automated NHSN reporting tools | No |
| BD HealthSight Clinical Advisor | Yes, stewardship alerts | Regional and national resistance benchmarks | AUR certification on the BD page | No |
| Harris Medici (Asolva) | Yes, stewardship module | Resistance reporting to NHSN | AU and AR validation claimed by Harris | No |
| Epic stewardship build and Bugsy | Yes, built by your analysts | Reports you build | Bugsy certified for AUR | Inside your Epic contract |
| Antimicrobe | No | Antibiogram, unit and source cuts, quarterly trends, MDRO watch | No | Yes, from $249 a month |
What antimicrobial use software has to do for NHSN
For most US hospitals the use side is no longer optional. CMS counts Antimicrobial Use and Resistance surveillance as a required measure in the Medicare Promoting Interoperability Program for eligible hospitals and critical access hospitals, and NHSN only accepts AU data as a CDA file from a vendor product that passed its synthetic data set validation. That rule is why every platform in the table leads with AUR.
Harris says Asolva's Medici was the first vendor solution to pass both the AU and the AR validations, and NHSN's list of vendors that passed AU validation includes Medici. Wolters Kluwer describes Sentri7 as NHSN-validated with one-click AUR. Inovalon sells AUR collection and NHSN submission in its VigiLanz Starter tier for small and critical access hospitals. Epic lists Bugsy as certified for AUR reporting, so an Epic hospital may already own this half.
Before you buy anything for AUR, check whether your EHR is already validated. The list and the trade-offs are in NHSN AUR reporting software compared.
Where resistance monitoring usually falls short
Ask any of the platform vendors for a demo of the antibiogram and you will usually see a report that exists. What you need to check is whether it applies the first isolate rule, flags organisms under 30 isolates, cuts by unit and specimen source, and lets you compare this quarter with last. Many hospitals that pay for a full surveillance platform still build the annual antibiogram in Excel because the built-in one does not match what the lab and the P&T committee expect.
That gap is the one Antimicrobe fills. It reads the susceptibility export from your LIS, applies the CLSI M39 rules, and gives you the cumulative antibiogram, resistance by unit and source, quarterly trends and an MDRO watch with thresholds. It does not read the medication record, fire patient alerts or submit to NHSN, so it runs beside whichever use tool you already have, or beside an EHR that already covers AUR.
The full scope of that resistance side, with the MDRO list and trend views, is on antimicrobial resistance surveillance software. The antibiogram on its own is on hospital antibiogram software.
How much does antimicrobial monitoring software cost?
No platform vendor publishes a price. VigiLanz discloses a one-time implementation fee plus an annual license in its certification disclosures, and Sentri7, TheraDoc, BD and Harris quote after a demo. Expect a quote sized by bed count and modules, plus interface work on your side, and a timeline measured in months.
Resistance monitoring alone costs much less because it needs no interface. Antimicrobe's Lab plan is $249 a month for one facility with the antibiogram and CSV and print exports. Stewardship, $749 a month for up to three facilities, adds unit and syndrome cuts, quarterly trend tracking and MDRO watch with threshold alerts. Annual billing is half the monthly price, and there is no implementation fee.
What hospitals actually budget for each route, including staff hours for the free ones, is broken down in antibiogram software cost, and every plan limit is on the pricing page.
Which antimicrobial monitoring software does a small hospital need?
Start with what your EHR already does. If it is validated for AUR, the use half is covered and the money should go to resistance monitoring and pharmacist time. If it is not, a lightweight AUR product such as VigiLanz Starter covers the CMS measure without paying for alerts a part-time program cannot staff.
Then look at the antibiogram. A 25 to 150 bed hospital rarely needs real-time alerts it has nobody to answer, but it does need an antibiogram that follows M39, pools years when counts are thin and shows the counts behind each percentage. That is a $249 a month problem, not a platform contract.
Standards move as well. The Joint Commission renumbered its stewardship requirements under Accreditation 360 from January 2026, and CMS updates the Promoting Interoperability measures each year. A small team that also tracks infection control, pharmacy and lab rules can keep up with those changes through a regulatory change monitoring tool rather than reading every bulletin.
The current Joint Commission requirements and how the antibiogram fits them are on Joint Commission antimicrobial stewardship. Smaller hospitals have their own buyer guide at antibiotic stewardship software for critical access hospitals.
Questions to ask in an antimicrobial monitoring software demo
- Which half do you monitor, use or resistance, and which features need a live EHR interface?
- Is the product on the NHSN list of validated AU vendors, and for which version?
- Show me the antibiogram on our own export. Does it apply the first isolate rule and flag cells under 30 isolates?
- Can I cut resistance by unit, specimen source and quarter without asking your support team?
- What is the one-time implementation fee, the annual license and the interface cost on our side?
- How many pharmacist hours a week do your reference sites spend answering alerts?
