Life Sciences and Clinical Translation

What standard applies to informed consent translation?

Informed consent has to be comprehensible to the person signing it, which makes reading level the controlling constraint rather than fidelity alone. Ethics committees review the translated version, so the target text is drafted to the same plain-language standard the protocol sets for the source.

A literal translation of a consent form written at graduate reading level is a compliant translation of a non-compliant document. Where the source is dense, we flag it rather than reproduce the problem, because the committee will raise it anyway and the cycle costs weeks.

Site-level detail matters too: contact names, local regulatory references and the ethics committee's own required wording differ by country, so the consent is localised per site, not translated once for a region.

Why do patient-reported outcome measures need back-translation?

Because a PRO instrument's score has to mean the same thing in every language, which is a measurement problem rather than a linguistic one. The established route is the ISPOR Principles of Good Practice, a multi-step process built to catch conceptual drift that a single translator would not see.

This is deliberately slower and more expensive than standard translation, and it is not substitutable. If an instrument is going to support an endpoint, the validation trail is part of what makes the data usable.

• Two independent forward translations, then reconciliation into one version
• Back translation into the source language by a translator who has not seen the original
• Back translation review to resolve every discrepancy against the source concept
• Harmonisation across languages, then cognitive debriefing with real patients

What languages does a device need for the EU and Brazil?

For the EU, Regulation 2017/745 leaves the specific languages to each member state, and in practice nearly all of them require their own official language for labelling and instructions for use. For Brazil, ANVISA submissions and product information are in Portuguese.

This turns language into a market-access decision: the countries you intend to sell into determine your translation scope and your update burden, because every labelling change propagates across every language version.

The practical mitigation is a maintained terminology base and translation memory across the whole product family, so a change to one warning is applied consistently everywhere instead of being retranslated from scratch each time.

Do you interpret for investigator meetings and audits?

Yes. Investigator meetings and advisory boards usually run with simultaneous interpreting, on site or remote. Inspections and site audits are consecutive, because the record has to be exact and the inspector controls the pace.
