A simple script to extract CTCAE terms from Excel and transform into terminology modesl for openEHR applications

CTCAE - terminology load and transform

What is it?

This is a quick and dirty application to read CTCAE terms from Excel and output resources to be used within openEHR based applications. The purpose is to extract the connection between categories, terms and grade inclusions.

How to run?

• Require Deno https://deno.land/manual@v1.32.3/getting_started/installation

deno run src/main.ts

Data

The CTCAE terminology is extracted from the following Excel spradsheet: https://evs.nci.nih.gov/ftp1/CTCAE/CTCAE_5.0/CTCAE_v5.0_2017-11-27.xlsx

In the following there are some text about CTCAE to introduce the terminology and the overall model/terminology.

Common Terminology Criteria for Adverse Events (CTCAE)

The NCI Common Terminology Criteria for Adverse Events is a descriptive terminology which can be utilized for Adverse Event (AE) reporting. A grading (severity) scale is provided for each AE term.

SOC

System Organ Class (SOC), the highest level of the MedDRA1 hierarchy, is identified by anatomical or physiological system, etiology, or purpose (e.g., SOC Investigations for laboratory test results). CTCAE terms are grouped by MedDRA Primary SOCs. Within each SOC, AEs are listed and accompanied by descriptions of severity (Grade).

CTCAE Terms

An Adverse Event (AE) is any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medical treatment or procedure that may or may not be considered related to the medical treatment or procedure. An AE is a term that is a unique representation of a specific event used for medical documentation and scientific analyses. Each CTCAE v4.0 term is a MedDRA LLT (Lowest Level Term).

Grades

Grade refers to the severity of the AE. The CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline:

• Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated.
• Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting ageappropriate instrumental ADL*.
• Grade 3 Severe or medically significant but not immediately life-threatening;hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL**.
• Grade 4 Life-threatening consequences; urgent intervention indicated.
• Grade 5 Death related to AE.
