MEDHOST antibiogram software for community hospitals that build the yearly antibiogram from MEDHOST Enterprise lab results

Where a MEDHOST antibiogram usually comes from today

MEDHOST does not publicly describe a CLSI M39 cumulative antibiogram report in Enterprise, and its customer documentation sits behind the MEDHOST Community login. In practice a MEDHOST hospital gets its antibiogram in one of three ways.

If Sentri7 already sits on your MEDHOST contract, ask whether its antibiogram covers what your committee wants before buying anything else. If you are weighing Sentri7 mainly for the antibiogram, compare the routes on Sentri7 alternatives first.

• From Sentri7, if the hospital licenses the suite. Wolters Kluwer says Sentri7 produces an antibiogram, alongside real-time stewardship alerts and NHSN reporting
• From the lab instrument data manager, such as a VITEK 2 or Phoenix data system, which sees only the isolates that instrument tested
• From a line list exported out of MEDHOST or the LIS and finished by hand in Excel, which is the most common route at a hospital under 100 beds

What goes wrong in the hand-built version

The spreadsheet route works until someone checks it. These are the problems that show up when a MEDHOST line list becomes an antibiogram in Excel, and each one moves real percentages at a community hospital where the denominators are small.

How small hospitals handle thin counts, pooled years and regional data is compared on critical access hospital antibiogram software.

• Repeat cultures counted as new isolates. Three positive urines from one patient in a month are one isolate under M39, and in a column of 50 E. coli the extra two shift the number by several points
• Reference lab results missing or duplicated. Results that arrived as text before the discrete interface, or that came back both ways, are easy to drop or count twice
• Preliminary results in the file. A report that pulls every result instead of finalized ones keeps susceptibilities the lab later corrected
• Thin organisms printed as percentages. Most community hospitals reach 30 isolates a year for E. coli and Staph aureus and for very little else
• Emergency, inpatient, swing bed and clinic cultures mixed in one table, because nobody split them by location on purpose

How to export antibiogram data from MEDHOST

Ask whoever writes lab reports, usually the lab manager, the MEDHOST system administrator or the analyst who supports pharmacy, for one delimited file of finalized microbiology susceptibility results for the analysis period. If microbiology is verified in a separate LIS, take the file from the LIS, because that is where the result is final. If most cultures go to a reference lab, ask for the lab's own line list too.

One row per organism and drug works, and so does one row per isolate with a column per drug. Include a patient identifier (a hashed one is fine), collection date, location or patient type, specimen source, organism, antimicrobial and the released interpretation. Keep the location column so the EDIS emergency department cultures can be split out, which matters because many community hospitals treat and discharge most of their urinary tract infections from the ED.

A column-by-column example of a clean export is on laboratory information system exports, and reference lab files are covered in antibiogram software for reference labs.

1. 1

   MEDHOST or LIS report

   Finalized susceptibility results for the year, with location and specimen source

2. 2

   CSV file

   One delimited export, plus the reference lab line list if cultures were sent out

3. 3

   Antimicrobe

   First isolate per patient, 30 isolate flag, years pooled when one year is too thin

4. 4

   Antibiogram

   House-wide, urine and ED tables with counts and a rule receipt for the committee

The free desktop route is WHONET, which reads the same delimited export. The practical trade-offs are on the WHONET alternative page.

Does a MEDHOST hospital need Sentri7 for NHSN AUR?

MEDHOST itself did not appear on the CDC NHSN vendor lists for the Antimicrobial Use or the Antimicrobial Resistance Option when we checked them in October 2026 (the lists were last reviewed on June 24, 2026 and May 12, 2026). Wolters Kluwer's Sentri7 does appear. That fits MEDHOST's own 2023 announcement, which offered Sentri7 to customers so they could submit AUR data to NHSN under the CMS Promoting Interoperability requirement. Confirm your own route with MEDHOST, because the lists change and can lag a new validation by two months.

The AUR files and the antibiogram start from the same finalized susceptibility results, but they serve different readers. AUR goes to NHSN. The antibiogram goes to your prescribers, your stewardship committee and the order sets. Antimicrobe does the second job only, so it works whether your AUR route is Sentri7, another certified vendor or something else.

Which AUR products CDC has validated, and what each costs, is compared in NHSN AUR reporting software compared.

Which plan fits a MEDHOST hospital

A single MEDHOST hospital producing a house-wide, urine and emergency department antibiogram needs the Lab plan, $249 a month for one facility, 25,000 isolates a year and two seats, bought by card with no implementation fee. Two seats usually means the pharmacist who owns stewardship and the lab manager or infection preventionist.

A hospital that also wants unit cuts, syndrome groups, quarterly trends and MDRO counts, or that reports an attached rural health clinic or nursing home as its own facility, uses Stewardship at $749 a month for up to three facilities. A multi-hospital MEDHOST system that wants one pooled regional report plus each hospital's own uses Network at $2,400 a month for twelve facilities. Annual billing is half the monthly price.

Every limit is on the pricing page. Community hospitals on other small hospital EHRs will find their route on CPSI EHR antibiogram software and Paragon EHR antibiogram software.

What this does not do

• It does not connect to MEDHOST directly or through HL7. It reads exported files, as often as you export them
• It does not reinterpret MICs or zone sizes. It uses the S, I and R your lab released
• It does not replace MEDHOST, your LIS or your reference lab interface for result entry, verification or reporting
• It does not submit antimicrobial use or resistance data to NHSN
• It does not send real-time alerts on individual patients, which is what Sentri7 is for
