About this study

Official title: TIMMY3 80601-2-56:2017 + A1 2018 Clinical Accuracy Study

The purpose of this document is to validate the clinical accuracy of the TIMMY3 thermometry module, integrated into host device CVSM, according to ISO 80601-2-56:2017 + A1 2018.

Read the detailed description

The purpose of this document is to validate the clinical accuracy of the TIMMY3 thermometry module, integrated into host device CVSM, according to 80601-2-56:2017 + A1 2018.

This study is designed to provide supporting documentation for the TIMMY3 module operating with SureTemp Plus algorithms. Testing will be performed with a production equivalent CVSM modified to use TIMMY3 (TIMMY3 investigational device), running the SureTemp Plus algorithms. The TIMMY3 module is intended to be integrated into additional Welch Allyn devices such as, but not limited to, the Connex Spot Monitor and Spot 4400. The process described below will be followed in accordance with the method called out in ISO 80601-2-56:2017 + A1:2018.

    Clinical repeatability is defined per ISO 80601-2-56:2017 + A1:2018 as the pooled within-subject standard deviation (SD) of triplicate device-under-test output temperatures for each anatomical site (refer to ISO formulas [5] and [6]). This outcome reports that SD as a single numeric value (°C); because it is a dispersion statistic (not a mean), no central-tendency measure applies. Higher SD indicates lower repeatability.

    Measured: 20-30 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Connex CVSM with Timmy3 module in people with Febrile Illness, run by Baxter Healthcare Corporation at 5 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Mar 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Validate the Clinical Accuracy of the Timmy3 Thermometer Algorithm for Age Group >=5 Years - Clinical Bias (time frame: 20-30 minutes). The study lists 15 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Mar 2026.
