The project is a temporary solution until a FHIR terminology server is available.

Purpose

The main purpose of this dictionary is to find list of ICD-10 codes by searching for words.

A list of ICD-10 codes can be retrieved by using the endpoint "/api/v1/icd" with queryparameter "searchword" - e.g.

http://localhost:8080/fhir/ValueSet/$expand?url=http://hl7.org/fhir/sid/icd-10-gm&filter=infektiös

Default parameters

variable Docker default value
application port 8080
database host ICD_DB_HOST localhost
database port ICD_DB_PORT 5432
database name ICD_DB_NAME icd10
database user ICD_DB_USER postgres
database password ICD_DB_PASSWORD password
pool size ICD_POOL_SIZE 30

Start postgres

For testing purposes one can start a postgres database with Docker using following comand:

docker network create -d bridge icd-net
docker run --name icd-postgres -d --network=icd-net -e POSTGRES_PASSWORD=password -p 5432:5432 postgres:alpine

Then create a database by executing a bash and using PSQL

docker exec -it icd-postgres bin/bash
psql -U postgres
CREATE DATABASE icd10;

Preparing data

To run the ICD-10 dictionary service the ICD-10 data must be present as a FHIR code system. For the ICD10-GM this can be achieve in following steps:

0.) Start a postgres database on port 5432

1.) Download ClaML-file (ICD-10-GM) https://www.dimdi.de/dynamic/de/klassifikationen/downloads/

2.) Clone the repository https://github.com/aehrc/fhir-claml and maven install the .jar-file

3.) Convert file to FHIR

java -jar fhir-claml-0.0.1-SNAPSHOT.jar 
    -i icd10who2019syst_claml_20180824.xml 
    -designations preferredLong 
    -o codesystem-icd10gm-2020.json 
    -id icd10gm2020 
    -url http://hl7.org/fhir/sid/icd-10-gm 
    -valueSet http://hl7.org/fhir/sid/icd-10-gm/vs

4.) Run the ICD-10 dictionary (as executable jar) and load the data by using the endpoint "/api/v1/icd/load" with the file path to the FHIR .json-file as body - e.g.

http://localhost:8080/api/v1/icd/load

C:\Users\xyz\icd-service\codesystem-icd10gm-2020.json

Remark: When working with Docker the file must be copied to a suitable location inside the container

docker cp C:\Users\xyz\icd-service\codesystem-icd10gm-2020.json [CONTAINER-ID]:/var/tmp/icd10

Docker

For building the docker container use

docker build -t icd-dictionary .

The command for starting the container is something like

docker run --rm -d -e "ICD_DB_HOST=icd-postgres" -p 8080:8080 --network=icd-net --name icd-dictionary icd-dictionary

Developers

This project uses lombok. Though it is not neccessary it is recomended to install a suitable lombok plugin for your IDE (e.g. for IntelliJ Idea install https://plugins.jetbrains.com/plugin/6317-lombok).
