Tetra handles the complexity so you can focus on your patients

Ai logo

AI-Powered

Our large language model (LLM), fine tuned for medical settings, reliably reads surgical free text to understand the planned procedure. It then categorises the procedure using a custom ontology that captures more detail and nuance than OPCS codes.

Procedure time prediction

By analysing historical performance, Tetra predicts the time each procedure will take, using an advanced statistical model that incorporates nuances of different surgeons & sites. By using a machine learning model, Tetra improves over time to get more accurate.

Session suggestions

Tetra then suggests which session to book into, accounting for equipment clashes and other constraints automatically, navigating rules that you can set. When slots become available, it scans the entire waiting list to find suitable procedures to book.

FAQs

What is Tetra?

Tetra is a theatre scheduling platform that helps waiting list coordinators and booking teams book elective procedures. Tetra is accessed via a web browser and pulls data from your theatre management system and PAS/EPR to work out the best possible sessions to run. Users use Tetra to book directly patients into theatre lists, and are provided with suggestions on the best procedures to book, powered by AI.

Does this replace my PAS/EPR/TMS?

Tetra integrates with, and works alongside, existing systems. By ingesting waiting list and clinical data from your EPR/PAS, Tetra provides users booking advice to create optimal theatre lists. Users can book surgeries using Tetra, and this can feed into the theatre management system.

How long does it take to get set up and what's involved?

Set up typically consists of 3 phases: information governance & data flow setup, model configuration & system integration, and user validation & UAT. At all stages, we have robust templates, documentation and resources that help speed things along.

Does my data have to be perfect?

No. No provider has perfect data quality. Our expert team will work closely with you to understand your limitations and build in accomodations, whether you are paper-based, do lots of manual entry, or struggle with RTT. Tetra can also highlight data quality issues, which can help teams locate and address gaps.

How secure is my data on Tetra?

Security is our top priority. Tetra uses end-to-end encryption, secure, UK-based data centres, and regular security audits to ensure your data is protected at all times. We apply role-based, and user based access controls to strictly manage permissions. We have cyber essentials certification and are both DTAC & DSPT compliant.

How much does Tetra cost?

The price of Tetra varies with the number of theatres you have and the volume of surgery being performed, with the price per theatre reducing significantly with increased volumes. At all levels, Tetra only requires a modest improvement in efficiency to provide a significant return on investment. Contact us to get an estimate.

What specialties can benefit from Tetra?

By collating all the relevant information for booking teams to make quicker scheduling  decisions and applying rules, Tetra can benefit every elective specialty. The AI & statistical models that Tetra uses typically benefit specialties with higher volumes and more variable procedure lengths like orthopaedics, urology or general surgery.
