Effective communication between patient and provider of medical
care is critical to the delivery of safe, high-quality care.
Patients have to understand the questions they are asked and the
information that is given to them.
Studies have shown:
Patients with low language proficiency are at increased risk of
experiencing an AE. The issue has been studied in countries with a
high proportion of new immigrants whose knowledge of English is
limited – US, Canada, Australia (1, 2). Lately such increased risk is
present also in the European Community due to greater patient
mobility (3).

Hence the safety of patients participating in a clinical trial may be
jeopardized because of their poor language proficiency and also
because of faulty translation of trial related documents.


Any inconsistency between the original text and the translated
one may lead to lack of comprehension or to
misunderstanding, bad decisions and dangerous activities

Inaccuracy may be critical

Use of high language may lead to misunderstanding,
withdrawal of the subject's consent, irrelevant concerns and
unnecessary fears

Omission of text – may be dangerous
INTRODUCTION – cont.
Documents written by of for
the Sponsor
Translator
Documents to Local Readers:
candidates, patients, investigators,
study staff, ECs, authorities, etc.
Documents written by local parties:
physicians,
authorities, EC, etc.
Sometimes the client’s expectations from the translated
document cannot be reached by the market since the
combination of professional translation and biomedical
knowledge is not common
8
INTRODUCTION – cont.
Every document has a purpose
ONE fundamental purpose:
To inform
(the participant – ICF
the attending physician – Form 11
the study team – patient diary
the investigator – investigator’s brochure…)
9
INTRODUCTION – cont.
The purpose determines the target reader.
Thus,
Every document has its target reader
Examples:
Informed Consent Form –
the candidate / volunteer
Protocol synopsis –
the investigators and study staff
IB –
the investigators
Safety reports –
the safety board
EC correspondence –
investigator/ sponsor
Patient diary –
the patient / and study staff
Patient emergency card –
anyone
Letters -
10
the attending physician, etc.
INTRODUCTION – cont.
Each target reader has its characteristics
Examples:
The candidate / patient / participant / volunteer: “the layman”, lacks
medical background, has an 8th grade reading level, sometimes is
sick, sometimes suffers from side effects, is under a lot of stress,
surrounded by advice givers
The sponsor, investigators and members of safety boards:
professionals, extensive medical background, specifically in the
study’s subject, busy, high academic reading level
The study staff - medical background, busy, academic reading level
11
INTRODUCTION – cont.
The information, vocabulary and style of the
document should be adjusted to the target reader
The translator should know the characteristics of the target reader
in order to create a document which fulfills its purpose.
If the translator does not know your reader – he/she should not
translate.
Not knowing the target reader is dangerous and may lead to
crucial safety risks.
12
INTRODUCTION – cont.
Safety risks to who?
Examples:
• The volunteer
• The volunteer's partner
• The volunteer pregnant partner
• The unborn child
• Family members (including children & elderly)
• Family friends
• Neighbors / The community
• The society / the study
• The environment
13
ANYONE ENGAGED OR INVOLVED IN THE STUDY
PART 1:
Poor Translation of Clinical Trial Documents Safety Risks to the Volunteer
1. Hazards in medication therapy
(both when self administered or given by others) –
Increase occurrence or severity of AEs
Examples: poor translation of:
- Prescription and administration of the trial medication:
name, dosage, route of administration
- Signs and symptoms to be looked for
- failure of the clinical trial team to elicit participant's symptoms
- Steps the volunteer or family may take to
prevent or minimize AEs
- Explanation of how and by whom the AE will be
treated, and to what medical
and chronological extent
- Explanation of how the study drug affects the
standard treatment the patient
is receiving
14
PART 1: Safety Risks to the Volunteer – cont.
The participant's limited ability to understand documents at a level that
permits effective interaction with the clinical trial team leads to
• failure of the participant to act as instructed
• disparities in prescription and administration of the study
preparation
• reduced likelihood for appropriate follow-up and treatment of the
underlying conditions and/or of side effects of the trial
It is CRUCIAL for these explanations to be translated clear and accurately in
a language understandable by the staff, patient and family
15
PART 1: Safety Risks to the Volunteer – cont.
2. Risks due to cultural differences, not properly adjusted by the
translation
Examples:

English text invites people to a clinic examination. In some countries this
should be modifies to house calls (in order to cover a family disease).

Food / beverages prohibited in certain religious (alcohol).

Is “room temperature” the same in Israel and Norway?

Questionnaires – risk of scoring differently than others around the globe
Verbal memories – recalling lists of words
BUT – words like “mink” and “lawn” are not usable in Israel, “cottage”
means cheese, China” means only a country
Letter fluency - naming as many items as possible that begin with that
letter
16
PART 2:
Poor Translation of Clinical Trial Documents Safety Risks to others
Examples:
The participant's partner: misunderstanding regarding diet, sex relations
(contraception - when, for how long, which?), behaviour, daily activity, mood
Participant's pregnant partner: unclarity regarding hazards to pregnancy / fetus
Unborn child of a participant / participant's partner: genetic hazards to future
generations
Family members and friends: errors in translation of storage and precautions required
Community: errors in precautions – infections, contaminations.
Society / Study: errors in reporting safety data to be analyzed for registration,
development of drug resistance
Environment: errors in instruction of disposal of radioactive ingredients, TB live
vaccines
17
PART 3:
Common problems of poor translation
1. Lack of professional medical background
1a. Medical vocabulary – using the right term:
Example - anatomy:
• Both breasts (pupils) are equal and reactive to light and
accommodation.
Example: pathology:
• Occasional, constant infrequent headaches
(Occasionally, infrequent persistent headaches)
18
PART 3: Common problems – cont.
More Examples:
•
She had no shaking chills, but her husband states she was very hot in bed
last night.
(She had no shaking chills but her husband states that she had high
temperature / fever in bed last night).
•
When she fainted, her eyes rolled around the room.
(When she fainted she rolled her eyes around the room).
•
Discharge status: Alive, but without my permission
(Discharge status: Alive. Discharged without my permission).
19
PART 3: Common problems – cont.
1b. Jargon – new areas ahead of language
Language in science is dominated by 2 contradictory trends:
Greater international unification - globalization of
scientific English
Growth of field-specific jargon - new terms to express
new knowledge
“Jargon” allow specialists to communicate precisely with one another.
Removing jargon or substituting it with another phrase can affect
interpretation.
Cat scan – is it “searching for kitty?
20
PART 3: Common problems – cont.
Problem – same words used in different jargons mean different things
(What is Plasma? Is it in the cell? Is in the blood? Is it a sterilization device
or a part of your TV screen?
THE DECISION IS DEPENDANT ON KNOWING THE TARGET READER!
21
PART 3: Common problems – cont.
Slang – a popular jargon
• Doc
• Over the counter
• Gay participants – are they merry?!
•
The pelvic exam will be done later on the floor
(The pelvic examination will be done later, in the ER department
(which is always on the ground floor and often called “the floor”).
•
Dr. Smith felt we should sit on her abdomen
(Dr. Smith felt we should discuss her abdomen
(‫)ד"ר סמית חשב שצריך לשבת על הבטן שלה‬.
•
Outpatient - A patient who has fainted?
22
PART 3: Common problems – cont.
1c. Acronyms and abbreviations
FDA, ICH, IEC, IRB, WHO, EMEA, PI, MedDRA, CRF, AE/SAE…
Professional background enables choosing the right full term for
the reader:
Example:
FDA: Food & Drug Administration ? / Functional Data Analysis ? /
Florida Dental Association ? / Foreign Disaster Assistance ? /
Frequency Domain Analysis ? / Federal Disaster Area ?
And knowing when they suit the professional reader
Example:
The SOP reg. an AE of abnormal AST (SGOT) or ALT (SGPT) levels, but
normal AUC or AUC(0-t), requires using the ANCOVA model. BMI, BP,
Bpm, HR, EF and ECG results will be documented in the CRF. IV PKs,
even when NCS or WNL will be expressed in mgs per mls.
23
PART 3: Common problems – cont.
2. Lack of knowledge of local and international health regulations,
clinical trials procedures, lack of commitment to GCP
requirements
Example: Length – a profound problem!
knowledge of local and international health regulations, clinical trials procedures,
and GCP requirements enables quality suggestions of shortening, if requested.
24
PART 3: Common problems – cont.
3. Lack of linguistic skills:
Tense
The past tense prevails in biomedical reports, except for “general
truths,” which are written in the present tense.
• The medication improves weakness.
• The medication improved weakness.
Future tense should be used in protocols but may confuse issues about
standard practices.
• Environmental controls will be set to maintain temperatures of 18o to
26oC.
• Environmental controls are set to maintain temperatures of 18o to 26oC.
25
PART 3: Common problems – cont.
Numbers
Doses, timetable of procedures, amounts of blood to be taken,
etc.:
Inaccuracy may be critical, even fatal.
Commas simplify the reading large numbers (23,450 vs. 23450)
but:
Many Europeans use the decimal point as a
comma, rather than a period (e.g. 23,450
means 23.450)
26
PART 3: Common problems – cont.
Never trust the auto speller – read again!:
• Examination of genitalia reveals that he is circus sized.
(Examination of genitalia revealed that he is circumcised).
• While in ER, she was examined, x-rated and sent home.
(While in ER she was examined, X rayed and sent home)
• The lab test indicated abnormal lover function.
(The lab test indicated abnormal liver function).
• The skin was moist and dry
(The skin was mostly dry)
27
PART 3: Common problems – cont.
4. Lack of translation skills:
4a. Lack of outmost preciseness
•
Using the signs > / < / = / ± / ≥ / ≤ in translating inclusion /
exclusion criteria
•
The patient has no previous history of suicides.
(The patient has no previous history of suicide attempts.)
•
On the second day the knee was better and on the third day it
disappeared.
(On the second day the knee was better and on the third the pain
/ swelling disappeared.)
28
PART 3: Common problems – cont.
4b. Lack of computer skills
Use of different programs, (online and hard copy)
dictionaries, templates.
High knowledge of implementation of footers, remarks,
comparison of documents, tabulating etc.
29
PART 3: Common problems – cont.
4c. Inconsistency
Typical of documents with multiple contributors
(protocol, clinical report, ICF).
all along the document internal consistency is important
regarding:
•
Language - level and terms used
•
Style
•
verb tense
•
Structure
30
PART 3: Common problems – cont.
Inconsistency – example:
The study product will be given to the subject by the investigator.
The study doctor will administer the investigational preparation
by injecting the experimental solution to the participant. After
receiving the pharmaceutical experimental product, the patient
will be requested by the physician to lie down in order to
receive additional trial drug.
The participant, the PI, the study drug – one term!
31
PART 4:
Understand the cost of poor translation
Physical / emotional harm
Misconduct of the trial
Money
Time
32
PART 5:
Fundamental Skills Needed for High Quality
Translation of Clinical Trials Documents
– minimizing errors and safety risks
A translator who knows the target reader
with:
1. Professional medical background (vocabulary, jargon, acronyms,
abbreviations; knowing when and how to seek dictionaries, text books,
specialists' assistance
2. Profound updated knowledge of relevant local and
international regulations and procedures (The ability to simplify
the text, the knowledge to suggest solutions)
3. High linguistic skills (tense, grammar)
4. High translation skills (outmost accuracy, computer skills, consistency)
