[Coding in general practice-Will the ICD-11 be a step forward?] | JoVE Visualize

Area of Science:

Medical Informatics
Health Services Research
Primary Care Medicine

Background:

Primary care physicians in Germany utilize diagnostic coding systems primarily for administrative purposes, not clinical benefit.
Current coding practices rely on the German Institute of Medical Documentation and Information (DIMDI) thesaurus or self-made cheat sheets, resulting in low coding quality.
Existing systems, including ICD-10 and its German adaptation, are deemed inadequate for primary care settings.

Purpose of the Study:

To evaluate the suitability of current diagnostic coding systems for German primary care physicians.
To identify challenges and potential improvements in primary care coding practices.
To explore alternative classification systems that could enhance coding quality and utility.

Main Methods:

Analysis of current coding practices and tools used by German primary care physicians.
Assessment of the adequacy of ICD-10 and the DIMDI thesaurus for primary care.
Review of potential benefits and drawbacks of implementing electronic health record (EHR) standardization and alternative classifications like ICPC-2.

Main Results:

Primary care physicians find current coding systems burdensome and not beneficial for their direct practice needs.
Coding quality is suboptimal but currently sufficient for the risk compensation scheme.
ICD-10 and the German thesaurus are not considered adequate; ICD-11 is not expected to be a significant improvement from a primary care perspective.
Electronic health record (EHR) implementation could standardize coding but might remain cumbersome compared to current methods.

Conclusions:

Neither ICD-10 nor the German thesaurus adequately serves primary care coding needs; ICD-11 offers limited advantages.
The International Classification of Primary Care (ICPC-2) presents a more suitable standard for primary care, with ICPC-3 under development.
Standardization through EHRs and improved inter-EHR communication, alongside physician-centric use cases, could enhance coding quality and utility.
