Oesophagogastric Cancer Calculator

Overview

The Oesophagogastric Cancer calculator uses the Oesophagogastric Cancer eRAT to determine a patient’s risk of having Oesophagogastric cancer based on the most recent data received from the clinical system for that patient and additional data that may be added by the user.

Usage

The Oesophagogastric cancer calculator is designed to be used by a clinician to calculate a patient’s risk score of Oesophagogastric cancer.

Technical Specification

Mandatory Items

• The patient must be aged 55 or over.

• The patient’s age and sex must be supplied.

• A haemoglobin reading and a platelet count must be supplied, and both must be greater than 0.

• All other symptoms are optional, and assumed to not exist if not supplied.

Inferred Items

• Raised platelets are inferred if the patient has a platelet count > 400.

• Nationally the current units of measure for haemoglobin changed from g/dl to g/l.
  The CDS tool takes account of this so that either set of units can be interpreted correctly.
  If a haemoglobin value is less than 35 then it is deemed to be g/dl and is converted to g/l by multiplying by 10.

• For men: If the g/l value is between 0 and 100 then the haemoglobin level is considered "very low". Values 100 or above, but less than 135 then are considered "low”.

• For women: If the g/l value is between 0 and 100 then the haemoglobin level is considered "very low". Values 100 or above, but less than 115 then are considered "low”.

Risk Scoring

• A risk greater than 5% is considered HIGH (RED)

• A risk score of between 2% and 5% inclusive is considered MODERATE (AMBER)

• A score of less than 2% is considered LOW (NO COLOUR)
