What is terminology management and why is it important for medical devices?

Terminology management is the systematic collection, administration, and maintenance of technical terms and their translations. For medical devices, it is particularly important because inconsistent terminology can cause misunderstandings among users that jeopardize patient safety. Standards such as IEC 62366-1 also require consistent naming throughout product documentation.

How do I create a terminology database for medical devices?

Start by extracting all technical terms from your existing documentation. Define the preferred designation in the source language for each term, add definitions and context information, and translate the terms into all target languages. Validate translations with subject matter experts and maintain the database continuously. Tools like manualworks offer integrated terminology management that supports this process efficiently.

Which standards govern terminology in medical devices?

Several standards are relevant: IEC 62366-1 (usability) requires consistent terminology in accompanying documentation. ISO 15223-1 defines standardized symbols and their designations. The MDR itself requires comprehensible information for the intended user in Annex I. Additionally, the UMDNS (Universal Medical Device Nomenclature System) contains standardized product designations.

Why Consistent Technical Terms Determine Safety and Compliance

Terminology as a Safety Factor

In medical technology, language is more than a means of communication — it is a safety instrument. When an instruction for use refers to a component as "locking mechanism" in one section and "safety system" in another, confusion arises. The user cannot be certain whether the same element is being referenced. In a clinical environment where quick and precise decisions are required, such confusion can have serious consequences.

The standard IEC 62366-1 on usability of medical devices explicitly requires that accompanying documentation is consistent and comprehensible. Inconsistent terminology is a frequent finding in usability audits and can lead to objections from Notified Bodies. ISO 14971 on risk management also considers misleading documentation as a potential risk that must be evaluated as part of the risk analysis.

Challenges in a Multilingual Context

The terminology challenge escalates exponentially once translations come into play. A term that is unambiguously defined in the German source language may have multiple possible translations in the target language. Without binding terminology specifications, different translators choose different terms — and consistency is lost.

A typical example: The German term "Gebrauchsanweisung" can be translated into English as "instructions for use," "user manual," "operating instructions," or "directions for use." Each of these terms carries a slightly different connotation in medical technology. Without a binding specification, inconsistencies arise that permeate the entire documentation portfolio.

With 24 EU languages, this problem multiplies accordingly. Without systematic terminology management, consistent multilingual documentation is simply unachievable. The challenge becomes particularly acute when different translation service providers work on different documents — without a shared terminology basis, inconsistencies are inevitable.

Best Practices for Terminology Management

Step 1: Terminology Extraction

Begin with a systematic analysis of your existing documentation. Identify all technical terms used in your IFUs, labels, and technical documentation. Pay particular attention to terms used differently across various documents — this is where the greatest improvement potential lies.

Step 2: Term Definition and Standardization

Establish a binding definition for each technical term. Determine the preferred designation in the source language and document which synonyms are permissible and which are prohibited. Consider the terminology of relevant standards such as ISO 15223-1, IEC 60601-1, and product-specific standards. Also document the context in which a term is used — this significantly helps translators with correct assignment.

Step 3: Multilingual Validation

Translate your terminology database into all target languages — ideally by specialist translators with medical device expertise. Have translations validated by native-speaking subject matter experts in each target market. Pay particular attention to terms that are used differently in different countries — such as between British and American English or between European and Latin American Spanish.

Step 4: Integration into the Translation Workflow

A terminology database is only effective when actively used in the translation process. Modern translation management systems like manualworks integrate the terminology database directly into the translator's workspace: technical terms are automatically recognized, the correct translation is suggested, and deviations trigger a warning.

Terminology and Regulatory Compliance

Terminology management is not an optional quality measure — it has direct regulatory relevance. The MDR requires in Annex I that information supplied with the product is comprehensible to the intended user. Inconsistent terminology undermines this comprehensibility and can lead to objections during conformity assessment.

Under ISO 13485, the terminology process should be documented as a controlled process in your quality management system. This includes responsibilities for terminology maintenance, approval processes for new or changed terms, and regular review of the terminology database. Notified Bodies are increasingly evaluating the quality of terminology processes as part of their audits.

Conclusion

Terminology management is the foundation for consistent, comprehensible, and regulatory-compliant product documentation. It protects patients from misunderstandings, accelerates the translation process, and reduces correction costs. Invest in a solid terminology database and consistently integrate it into your documentation and translation workflow. The investment pays for itself quickly — through higher quality, shorter turnaround times, and fewer regulatory objections.
