1. The Belgian Bilingual Biclassified Thesaurus
Michel De Jonghe
University of Brussels
Department of General Practice

2. Introduction

3. The thesaurus
In 2001, the Ministery of Health asked two universities (Ghent and Brussels) to make a thesaurus.
Obligations :
Bilingual : Dutch / French
Must include 2 classifications :
ICD-10
ICPC-2
Information integrity in case of communication of medical information between two praticians.

4. (combined in one tool: ICPC2-ICD10 thesaurus)
Why biclassified ?
In general practice, the patient’s electronic record requires :
The possibility to analyse the activity in general practice: ICPC-2
diagnosis specificity: ICD-10
(combined in one tool: ICPC2-ICD10 thesaurus)

5. At the same moment : The labellisation of the medical software
Obligation of structuration (SOAP and EPR architecture)
Use of ICPC and ICD-10
Use of a medication data bank
Exportation of personal information : security and confidentiality

6. Why a medical software ? For the patient For the GP
For micro-epidemiology
For macro-epidemiology
The aim = quality of health

7. First point
The structuration

8. The contact (SOAP) Subjective : Reason for encounter Objective :
Medical examination, laboratories, referrals, …
Assessment :
Clinical labelling
Plan :
Process, terms

9. Proposal for Belgian EPR architecture
7 Basic concepts per patient record

10. Integration of all classical concepts in a simple format
Chronological registration of all services and diagnoses (hospitalization record)
SOAP
List of the problems and list of the episodes
Episodes registration

11. Second point

13. The Belgian thesaurus

14. At the beginning Amsterdam (Henk Lamberts) 125 000 lines
Translation from Dutch to French but no link between the two languages
DOS (A1 = A2 ; A1 = B+C ; A2 = C+B)
“Lobular pneumonia” = lobular + pneumonia
“Lobular pneumonia” = pneumonia +lobular

15. The thesaurus structure
IBUI = Unique number for identification for each line of the thesaurus (8 characters)
Clinical labelling_FR = FR_CLINICA
Clinical labelling_NL = NL_CLINICA
ICPC_code
ICPC_labelling
ICD-10_code
ICD-10_labelling
FR_REF_IBUI
NL_REF_IBUI +
Search-terms (= relevant words of all the labellings) = other file

16. Difficulties
Perfect translation from Dutch into French with respect of the two languages
Clinical label
management of double
Correlation between the clinical labelling and the ICD-10 labelling
Correlation between ICD-10 and ICPC-2 (mapping : WICC)

17. Specificity of the Belgian thesaurus
The REF_IBUI :
Makes it possible to respect the specificity of each language (Dutch / FR) :
Fr_CLINICA
Nl_CLINICA
Fr_REF_IBUI
Nl_REF_IBUI
IBUI
shigellose à Shigella sonnei
Sonne
infectie, Shigella, sonnei

ICD-10 : I41.0 (remplace A01.1)

23. Exemple 2 Intoxication alimentaire par crustacés :
ICD-10 : T61.2 (remplace A05.9). Il faut noter que aussi bien dans l’intitulé français que néerlandais, il n’est pas fait allusion à une infection bactérienne).
