Anyone who has worked with medical device documentation will know that translating an Instruction for Use (IFU) is very different from translating a brochure or marketing campaign.
The purpose of an IFU is not to sell a product. It is to provide clear, accurate information that enables a device to be used safely and correctly. As a result, accuracy, consistency and compliance must always take precedence over creative writing.
Whilst that might sound straightforward, achieving the right balance between readability and precision is often one of the biggest challenges in medical device translation.
Why IFU Translation Matters
Medical device IFUs contain information that directly affects patient safety, user safety and regulatory compliance.
Depending on the device, an IFU may include:
Every piece of information has been carefully reviewed before publication. Manufacturers invest significant time and resources in drafting, reviewing and approving these documents to ensure they meet both regulatory requirements and product safety standards.
When the document is translated, that same meaning must be carried across into the target language.
More Than Just a Language Exercise
One of the biggest misconceptions about translation is that the goal is simply to make the text sound natural in the target language.
Of course, readability is important. End users need instructions they can understand easily and follow confidently.
However, medical device documentation is not purely a linguistic exercise. It also involves preserving technical accuracy and maintaining the intent of the approved source document.
A translator’s role is not to improve upon the source text. It is to communicate the same information clearly and accurately in another language.
Balancing Accuracy, Readability and Compliance
I was reminded of this recently during a medical device IFU project that underwent an in-country review.
The reviewer proposed a substantial number of amendments throughout the document. Many of the suggestions were entirely understandable and appeared to be aimed at improving the flow and readability of the text for local users.
As part of the review process, we assessed each proposed amendment against the approved English source document.
In doing so, we found that some of the suggested changes, whilst well intentioned, had subtly altered the meaning of the original text. The revised wording often sounded perfectly natural in the target language, but it no longer reflected the approved source as accurately as the original translation.
This presented an important consideration.
The English source document had already passed through the manufacturer’s internal approval process, including legal and regulatory review. Every statement had been scrutinised and approved before the document was released for translation.
Once a translation begins to move away from that approved source meaning, there is a risk that it also moves away from the legal and regulatory position that has already been signed off by the manufacturer.
That does not mean translations should be overly literal. Good translation requires judgement, cultural awareness and an understanding of how technical information is communicated in the target market. However, in regulated industries such as medical devices, readability should never come at the expense of accuracy or compliance.
The experience served as a useful reminder that translation review is not simply about making text sound better. It is about ensuring that the translation remains accurate, clear and compliant whilst faithfully communicating the meaning of the approved source document.
Consistency Is Essential
Medical device manufacturers rarely produce a single document in isolation.
The same terminology often appears across:
Inconsistent terminology can cause confusion for users and create unnecessary complications during regulatory review.
This is why terminology management plays such an important role in medical device translation. Establishing approved terminology and applying it consistently across all documentation helps maintain clarity and reduces risk.
The Importance of Subject Matter Expertise
Medical device translation requires more than linguistic ability.
Translators must be comfortable working with medical, technical and regulatory content, often within the same document. They need to understand not only what the words mean, but also how they function within a regulated environment.
A seemingly minor change in wording can sometimes have implications that are not immediately obvious to someone outside the sector.
This is one reason why specialist medical device translators and reviewers are so valuable. Their expertise helps ensure documentation remains accurate, appropriate and compliant across every language version.
Final Thoughts
One of the biggest misconceptions in translation is that the best translation is the one that reads most elegantly.
In medical device documentation, that is not necessarily true.
The best translation is the one that faithfully communicates the approved source meaning, uses the correct terminology and enables users to operate the device safely and effectively.
Natural, readable language is important. However, when patient safety, regulatory compliance and legal accountability are involved, accuracy must always come first.
