This ROTEM calculator is served as a clinical decision aid and does not replace clinical judgement. Calculation outcome must be re-checked by healthcare professional and should not be used alone to guide patient care. It is the users' responsibility to ensure data entry of ROTEM result is accurate in order for the tool to provide reliable results.
This calculator is developed by Dr. Jun Jack Wong (GMC 7017779) as part of a QI project for Critical Care department, Aintree University Hospital in 2024. The code is written in html and javascript based entirely on the LUHFT Massive Haemorrhage Guideline without any deviation. There is no Artificial Intelligence involved in interpreting user input data.
This tool had been checked against at least 60 real ROTEM result (around 10% of annual ROTEM test sent in Aintree Hospital) during the pilot phase with human interpretation as comparison with robust accuracy result. This is with the help of Dr Imogen Watkins from Anaesthetic Department and Dr Rebecca Hughes from Critical Care department
