Antibiogram software cost and what a hospital pays for the cumulative antibiogram, route by route
Nobody publishes what an antibiogram costs, because in most hospitals it is a line hidden inside a surveillance platform contract, an EHR build queue, or one pharmacist's spring. Here is what each route actually costs, and the one price that is public.

Antibiogram software cost depends on which of five routes a hospital takes. A dedicated reporting tool is the only route with a published price: Antimicrobe runs from $249 a month for one facility. Enterprise surveillance platforms such as VigiLanz, Sentri7 and TheraDoc bundle the antibiogram with alerts and NHSN AUR reporting and quote per organization, typically as a one-time implementation fee plus an annual license, with no public figures. An Epic build costs analyst hours rather than a license. WHONET has no license fee but consumes a trained person's time on a Windows PC, and the Excel route costs a pharmacist somewhere between a few days and a few weeks every year.
This article is for the pharmacy director, stewardship pharmacist, microbiology manager or quality lead who has to put a number in a budget request. Vendors are described only from their own published pages, read in September 2026, and every figure that is not published is labeled that way rather than guessed.
Antibiogram software cost by route
The table below separates the license from the two costs that usually decide the real number: what it takes to implement, and whose hours do the work every year. "Not published" means the vendor states no price publicly, which is normal for enterprise clinical software and is not a criticism.
| Route | License | Implementation | Whose hours, every year | What you get |
|---|---|---|---|---|
| Excel, built by hand | None | None | One pharmacist or microbiologist, 20 to 60 hours a year in our estimate | One facility-wide cut, rules living in someone's head |
| WHONET (WHO Collaborating Centre) | None, free desktop software | BacLink configuration for your LIS export, Windows 10 or 11 only | The person who learned WHONET, each time the export changes | Full antibiogram analysis, single user, no web access |
| Enterprise platform (VigiLanz Pro, Sentri7, TheraDoc, BD HealthSight) | Not published; VigiLanz discloses a one-time implementation fee plus annual license | EHR, LIS and eMAR interface project, months | Pharmacy IT and the vendor, plus the alert queue | Antibiogram bundled with alerts, worklists and NHSN AUR |
| Epic build | Inside the EHR license | Analyst build and validation | Your Epic analysts, at the back of the queue | Whatever your build includes, certified AUR through Bugsy |
| Antimicrobe | $249 a month (Lab), $749 (Stewardship), $2,400 (Network), published | A CSV export from the LIS, no interface | The person who runs the export, about an hour a quarter | CLSI M39 style antibiogram, unit and source cuts, trends, empiric rankings |
How much does antibiogram software cost on an enterprise platform?
No enterprise vendor publishes a price, so the honest answer is a structure rather than a number. Inovalon's ONC disclosure for VigiLanz describes a one-time implementation fee and an annual licensing fee. Wolters Kluwer, Premier and BD offer demo requests and quote per organization. Two things matter more than the headline figure when the quote arrives. First, the antibiogram is usually not on the tier you are offered first: Inovalon sells VigiLanz Starter to small and critical access hospitals for AUR reporting and lists the on-demand antibiogram under Pro. Second, the implementation fee buys an interface project, and your own IT hours on that project are a cost the quote does not show.
If you already run one of these platforms, the marginal cost of the antibiogram is whatever the tier upgrade costs at renewal. If you are buying a platform for the antibiogram alone, you are paying for alerts, worklists and NHSN submission that a smaller hospital may not use, which is the case the next section is about.
Our pages on VigiLanz alternatives and Sentri7 alternatives break down what each platform covers beyond the antibiogram, tier by tier.
What AMS implementation cost really includes
Budget requests for stewardship software fail on the hidden lines, not the license. Whatever route you take, the antimicrobial stewardship implementation cost has four parts, and only the first one appears on a vendor quote.
The security review is the line most often forgotten. A platform that receives identifiable patient data needs a BAA and a real look at its controls, and vendors that keep their SOC 2 and HIPAA control mapping current move through that review in weeks rather than months. A CSV tool that only needs a pseudonymous patient key, which is what Antimicrobe uses for the first isolate rule, shortens the review because no direct identifier has to leave the LIS.
- License and implementation fee: the quote itself, annual for platforms, monthly for a reporting tool, zero for WHONET and Excel
- Interface work: ADT, eMAR, lab and microbiology feeds for a platform, or a BacLink map for WHONET, or a saved LIS export for a CSV tool
- Security and procurement review: your IT security office will ask a hosted vendor for its HIPAA safeguards, a business associate agreement where identifiable data leaves the building, and often a SOC 2 report
- People: the pharmacist or analyst hours to configure rules, validate the first report against last year's, and rerun it every quarter
Is antibiogram software worth it for a small hospital?
Yes, if the alternative is a pharmacist rebuilding the report by hand every spring or a regional antibiogram standing in for your own data. The CMS infection prevention condition of participation at 42 CFR 482.42, and 42 CFR 485.640 for critical access hospitals, require an active antibiotic stewardship program, and The Joint Commission's medication management standard asks the program to show how it tracks resistance. A cumulative antibiogram is the standard evidence. At $249 a month, a reporting tool costs less than the pharmacist hours it replaces at most hospitals, and it produces the unit and source cuts a hand-built report never gets to.
The break-even is simple to run for your own facility. Count the hours the last antibiogram took, including the P and T committee questions it generated, multiply by the loaded hourly rate of whoever did it, and compare that to twelve months of the tool. Then add what the report was missing: cuts by ICU versus wards, by urine versus blood, quarterly trends, and the MDRO counts surveyors ask for.
The free routes are not free
WHONET is genuinely free, well maintained by the WHO Collaborating Centre at Brigham and Women's Hospital, and used worldwide. Its cost is a person. Someone has to install it on a Windows 10 or 11 machine, configure BacLink for your LIS export format, learn the analysis screens, and repeat the import every quarter. When that person leaves, the antibiogram leaves with them. It is single user and desktop only, so the stewardship pharmacist, the micro lab and the infection preventionist cannot look at the same report in a browser.
Excel is the same trade with fewer safeguards. The first isolate rule, the 30-isolate floor, intermediate handling and breakpoint versions all live in one person's workbook, and the committee has no way to check them. The hours are real even though no invoice arrives.
If WHONET is the route you are weighing, the WHONET alternative page compares it feature by feature, including what it does better. All eight routes, from Excel to enterprise platforms, are ranked side by side in best antibiogram software for hospitals.
What Antimicrobe costs, exactly
Antimicrobe publishes every plan and every limit. The Lab plan is $249 a month for one facility, 25,000 isolates a year and two seats, bought by card on the site. Stewardship is $749 a month for up to three facilities, 150,000 isolates and eight seats. Network is $2,400 a month for up to twelve facilities with cross-facility comparison, 750,000 isolates and 25 seats. Enterprise, with unlimited facilities, a BAA and an HL7 or FHIR feed, is priced on a conversation. There is no implementation fee and no interface: the input is the finalized susceptibility CSV your LIS already exports.
What that buys is the cumulative antibiogram done the way CLSI M39 describes, with the first isolate rule, the 30-isolate floor, a named breakpoint set, cuts by unit, specimen source and quarter, MDRO phenotype counts, and empiric options ranked by local percent susceptible. It does not buy real-time alerts, NHSN AUR submission or an EHR interface, and a hospital that needs those should budget for a platform and consider running the antibiogram separately.
The full plan table is on the antimicrobial stewardship software pricing page, and the hospital antibiogram page shows the finished report. You can run the builder above on sample data before you spend anything.
Questions to ask before you sign any antibiogram quote
- Which tier includes the cumulative antibiogram, and what does the upgrade cost at renewal?
- Is the implementation fee one-time, and how many of our own IT hours does the interface need?
- Does the report print its de-duplication rule, isolate threshold and breakpoint version on the page?
- Can we cut by unit, specimen source and quarter without a change request?
- What patient identifiers leave the building, and is a BAA included at this price?
- What happens to the report if the one person who runs it leaves?
