Bilingual Cancer Consent Forms Improve Understanding for Limited English Speakers

For individuals facing a cancer diagnosis while navigating a new language, understanding treatment options can be profoundly challenging. A newly published study reveals a significant improvement in comprehension when bilingual consent forms are used, increasing understanding of cancer treatment aims from 35% to 60% among Bengali- and Sylheti-speaking adults in the UK. This finding underscores the critical role of accessible information in equitable healthcare.

Bridging the Language Gap in Cancer Care

The research, appearing in the journal Supportive Care in Cancer, focused on a population often underserved by standard medical communication practices. Limited English proficiency (LEP) is increasingly recognized as a barrier to quality healthcare, contributing to poorer outcomes across a range of conditions, including cancer. The study specifically examined Bengali- and Sylheti-speaking communities in the UK, groups identified as having high rates of LEP and experiencing disproportionately worse health outcomes compared to the broader UK population as noted in a related study.

Cancer treatment decisions are complex, involving discussions about potential benefits, risks, and side effects. A clear understanding of these elements is essential for informed consent – the principle that patients have the right to make autonomous choices about their care. When language barriers exist, this process can be compromised, leading to anxiety, mistrust, and potentially, suboptimal treatment adherence.

Study Design and Findings: A Closer Look

Researchers conducted a randomized study involving healthy, Bengali- or Sylheti-speaking adults with LEP in London. Participants were first assigned to receive either a machine translation or a professional (human) translation of an English-language systemic anti-cancer treatment (SACT) information booklet. Subsequently, they participated in a simulated SACT consent consultation with a doctor and interpreter, and were then given either a conventional English-only consent form or a bilingual English–Bengali consent form.

While the study found that providing a bilingual consent form significantly improved understanding of treatment intent, it’s important to note that the initial reading of translated booklets did not show a significant difference in comprehension between those who received machine translation versus professional translation. Only 15.7% of participants (19 out of 121) met the primary outcome of understanding treatment intent after reading the translated booklet, regardless of the translation method. However, the machine-translated booklet contained a notable number of errors – 11 meaning-changing errors – compared to just one in the professionally translated version. This highlights the potential pitfalls of relying solely on automated translation for sensitive medical information. Medical Xpress provides further details on the study’s methodology.

What is Systemic Anti-Cancer Therapy (SACT)?

Systemic anti-cancer therapy, or SACT, refers to treatments that travel throughout the body to reach cancer cells. This includes chemotherapy, immunotherapy, targeted therapy, and hormone therapy. Unlike localized treatments like surgery or radiation, SACT addresses cancer that may have spread beyond its original site.

The Importance of Professional Translation and Interpretation

The study’s findings reinforce the demand for high-quality, culturally sensitive translation and interpretation services in healthcare settings. While machine translation is rapidly evolving, It’s not yet reliable enough to replace the nuanced understanding and accuracy provided by professional translators, particularly when dealing with complex medical concepts. The presence of meaning-changing errors in the machine-translated booklet underscores this point.

the study highlights the value of bilingual consent forms, even when accompanied by an interpreter during the consent consultation. The form serves as a valuable reference point for patients and their families, allowing them to review the information at their own pace and reinforce their understanding.

Beyond Bengali and Sylheti: Implications for Diverse Populations

While this research focused on Bengali- and Sylheti-speaking communities in the UK, the implications extend far beyond these specific groups. The principles of accessible communication apply to all individuals with LEP, regardless of their language background. The US Census Bureau estimates that over 67 million people in the United States speak a language other than English at home, representing more than 20% of the population. Life Technology notes the broader relevance of these findings.

Healthcare providers and institutions have a responsibility to ensure that all patients have access to clear, understandable information about their care. This includes providing translated materials, qualified interpreters, and culturally appropriate communication strategies.

What Comes Next: Refining Approaches to Language Access

The researchers acknowledge that further investigation is needed to optimize translation approaches for SACT information. Future studies could explore the effectiveness of different translation methods, the role of visual aids, and the impact of patient education materials tailored to specific cultural contexts. The study authors suggest that ongoing evaluation of translation quality and patient comprehension is crucial to ensure that language access services are meeting the needs of diverse populations.

there is a need for greater awareness among healthcare professionals about the challenges faced by patients with LEP and the importance of utilizing available language access resources. Training programs could be developed to equip providers with the skills and knowledge necessary to effectively communicate with patients from diverse linguistic backgrounds.
