CPSI EHR antibiogram software that turns a TruBridge EHR lab export into a CLSI M39 antibiogram for a small hospital

Where a CPSI antibiogram usually falls short

TruBridge does not publicly describe a ready-made CLSI M39 cumulative antibiogram report. Its public pages and its CAP TODAY survey entry cover the LIS and its microbiology module, and the user guides sit behind a customer login. In practice most CPSI hospitals build the yearly antibiogram from a report or a line list and finish it by hand, which is where these problems come in.

Small hospital options for pooling, regional data and counts are compared on critical access hospital antibiogram software.

• Thin denominators. A 25-bed hospital may reach 30 isolates for E. coli in a year and for little else, so most cells either need pooled years or should be shown as counts
• Duplicate cultures. A patient with four positive urines is one isolate under M39, and in a denominator of 40 the extra three move the percentage by several points
• Send-out results. Cultures read at a reference lab come back into the chart, but sometimes as a scanned report instead of discrete results, and those never reach a query
• Mixed settings. Swing bed, rural health clinic and attached nursing home cultures sit in the same system and get pooled with inpatients or dropped without anyone deciding which
• One person, once a year. The pharmacist who builds it in January has not touched the spreadsheet since last January and rebuilds the formulas from memory

How to export antibiogram data from TruBridge EHR

Ask whoever runs reports for the lab, often the lab manager or the hospital's TruBridge system administrator, for one delimited file of finalized microbiology susceptibility results for the analysis period. One row per organism and drug, or one row per isolate with a column per drug, both work. The columns that matter are a patient identifier (hashed or pseudonymous is fine), collection date, location or patient type, specimen source, organism, antimicrobial and the released interpretation.

Keep a patient type or location column so inpatient, emergency, clinic, swing bed and nursing home cultures can be cut apart or pooled on purpose. If some cultures are sent out, check that the reference lab results came back as discrete results and not only as a scanned report. If they did not, most reference labs will send a CSV line list for your facility on request, and that file can be added beside the TruBridge export.

WHONET users should know that BacLink has no ready-made template for TruBridge or CPSI. The WHONET guide to laboratory information system exports gives detailed templates only for MEDITECH Magic and Cerner Classic and asks every other LIS for a delimited text export. That is the same file Antimicrobe reads.

What a good laboratory export looks like, column by column, is on laboratory information system exports.

1. 1

   TruBridge EHR report

   Finalized culture and sensitivity results for the year, with patient type and specimen source

2. 2

   CSV file

   One delimited export, plus a reference lab line list if some 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 and urine tables with counts, the pooling window and a rule receipt

TruBridge reports, WHONET and Antimicrobe compared

WHONET is the free route and suits a lab with time to learn it on a Windows machine. The practical differences are on the WHONET alternative page.

Does a CPSI antibiogram follow CLSI M39?

It follows M39 only as far as the report and the spreadsheet do. TruBridge stores the results. Whether the first isolate per patient per period is kept, whether results that were not final are left out, whether species under 30 isolates are suppressed and whether pooled years are labeled is decided by whoever builds the report.

For a small hospital the 30 isolate rule matters more than anything else on the page. CLSI M39 recommends not printing a percent susceptible on fewer than 30 isolates. The honest alternatives are pooling two or three years with the window printed, showing the raw count, or pointing prescribers to a regional report. Antimicrobe does all three and prints a rule receipt with isolate counts before and after de-duplication, so the committee and a surveyor can see how each number was made.

Each M39 rule and how common tools handle it is on CLSI M39 antibiogram software.

What the IKS Health acquisition means for TruBridge hospitals

TruBridge is no longer a public company. Inventurus Knowledge Solutions, the US arm of India-based IKS Health, agreed to buy it on April 23, 2026 for $26.25 a share in cash and completed the acquisition on July 9, 2026, when TruBridge stock stopped trading on Nasdaq. TruBridge said at signing that the combined company would support more than 2,000 healthcare organizations.

Nothing in the deal documents says what changes for the EHR or the lab system, and it would be guesswork to predict. What a hospital can control is how much of its antibiogram depends on any one vendor's report builder. A report built from a plain CSV keeps working through upgrades, a new owner's roadmap or a later EHR change, because the rules live in the report tool and not in the LIS.

Which plan fits a CPSI hospital

A single TruBridge hospital producing a house-wide and urine 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 and no interface. Two seats usually means the pharmacist who owns stewardship and the infection preventionist or lab manager.

A hospital that also wants unit cuts, syndrome groups, quarterly trends and MDRO counts, or that reports for an attached clinic and nursing home as separate facilities, uses Stewardship at $749 a month for up to three facilities. A rural network or a group of TruBridge hospitals pooling a regional report uses Network at $2,400 a month.

Every limit is on the pricing page. How small hospitals compare stewardship tools more broadly is covered in antibiotic stewardship software for critical access hospitals.

What this does not do

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