This ROTEM calculator serves as a clinical decision aid and does not replace clinical judgment. Calculation outcomes must be re-checked by healthcare professionals and should not be used alone to guide patient care. It is the user's responsibility to ensure accurate data entry of ROTEM results for the tool to provide reliable outcomes.
This calculator was developed by Dr. Jun Jack Wong (GMC 7017779) as part of a Quality Improvement (QI) project for the Critical Care Department at Aintree University Hospital in 2024. The code is written in HTML and JavaScript, based entirely on the LUHFT Massive Haemorrhage Guideline without deviation. No Artificial Intelligence is involved in interpreting user input data. Please note that this calculator does not cover the 'Early Hyper Fibrinolysis' part.
This tool has been checked against at least 60 real ROTEM results (representing around 10% of annual ROTEM tests conducted at Aintree Hospital) during the pilot phase, with human interpretation used as a comparison, showing robust accuracy. Special thanks to Dr. Imogen Watkins from the Anaesthetic Department and Dr. Rebecca Hughes from the Critical Care Department for their assistance.
This is a registered project under the Research and Innovation Department at Liverpool University Hospital NHS Foundation Trust as of July 2024. The project ID is 244. This web application qualifies as a decision aid and is not classified as a medical device.

This project is proudly sponsored by DayOne Trauma Support, which helps fund the domain and hosting services required to keep this service active. Once the initial funding expires, usage statistics will be used to justify ongoing funding from other sources.
This tool undergoes quarterly random quality control testing by Dr. Jun Jack Wong to ensure its continued validity according to the latest trust ROTEM guidance.
This decision checker is not part of regular services provided by Liverpool University Hospital NHS Foundation Trust, and its availability depends entirely on developer maintenance and commercial hosting service uptime. Liverpool University Hospital NHS Foundation Trust has no responsibility or obligation to provide ongoing support or troubleshooting if this service becomes unavailable.
All data entered in the calculator is not stored or submitted elsewhere. The website has a built-in visitor history tracker to provide insights into calculator usage, which may inform future funding.
