Informed choice to undergo prenatal screening for thalassemia: a description of written information given to pregnant women in Europe and beyond

Social and cultural influences on genetic screening programme acceptability: A mixed-methods study of the views of adults, carriers, and family members living with thalassemia in the UK

As population‐level carrier screening panels for reprogenetic information emerge globally, conditions to be included, and the timing of implementation is widely debated. Thalassemia is the only condition for which population‐based prenatal carrier screening is offered in the UK. However, little is known about the views and experiences of the UK thalassemia‐affected community toward this screening or other forms of genetic screening for thalassemia (newborn, preconception), despite the range of direct consequences of screening programmes for this group.

Using a mixed‐methods integrative analysis (qualitative interviews n = 20 and quantitative survey n = 80), this study outlines the experiences and attitudes of adults with thalassemia, their family members, and screen‐identified thalassemia carriers toward preconception, prenatal, and newborn screening for thalassemia. The majority of participants described thalassemia as a burdensome condition with a range of negative impacts, which contributed to their strong support for screening in all its potential formats. However, the data also highlight the challenges of each screening mode for this group, reflected in the high level of value conflict in participants' accounts and decisions. Cultural, social, and (to a lesser extent) religious factors were found to mitigate against the advantages of early screens, particularly within faith communities. Social stigma emerged as key to this process, informing the way that thalassemia severity was not only perceived, but also experienced by affected adults, which ultimately influenced screening uptake and outcomes.

These findings suggest that cultural and social sensitivity is as important as the mode of screening delivery itself, if the iatrogenic and unintended harms of screening—particularly the social/psychological burden of value conflict—are to be adequately addressed and minimized.

Ethical, social, and cultural issues related to clinical genetic testing and counseling in low- and middle-income countries: a systematic review

PURPOSE

We performed a systematic review of the ethical, social, and cultural issues associated with delivery of genetic services in low- and middle-income countries (LMICs).

METHODS

We searched 11 databases for studies addressing ethical, social, and/or cultural issues associated with clinical genetic testing and/or counselling performed in LMICs. Narrative synthesis was employed to analyze findings, and resultant themes were mapped onto the social ecological model (PROSPERO #CRD42016042894).

RESULTS

After reviewing 13,308 articles, 192 met inclusion criteria. Nine themes emerged: (1) genetic counseling has a tendency of being directive, (2) genetic services have psychosocial consequences that require improved support, (3) medical genetics training is inadequate, (4) genetic services are difficult to access, (5) social determinants affect uptake and understanding of genetic services, (6) social stigma is often associated with genetic disease, (7) family values are at risk of disruption by genetic services, (8) religious principles pose barriers to acceptability and utilization of genetic services, and (9) cultural beliefs and practices influence uptake of information and understanding of genetic disease.

CONCLUSION

We identified a number of complex and interrelated ethical, cultural, and social issues with implications implications for further development of genetic services in LMICs.

Informed choice in prenatal testing: a survey among obstetricians and gynaecologists in Europe and Asia

PURPOSE

To ascertain the extent to which the value obstetricians and gynaecologists attach to informed choice in the context of prenatal testing varies across countries.

METHOD

The values attached to informed choice and the perceived importance of test decisions reflecting the views of others considered significant to pregnant women were assessed and compared across obstetricians and gynaecologists in six countries: UK (n = 176), Netherlands (n = 331), Italy (n = 254), Greece (n = 116), China (n = 116) and India (n = 123).

RESULTS

While respondents from the United Kingdom and the Netherlands almost unanimously believed prenatal testing should reflect a parental choice (94%), substantial minorities in Greece, India, and China and to a lesser extent Italy, believed testing should either reflect a family choice or no choice (11-41%). Respondents who attached a low value to the views of others attached greater value to parental choice. Multinomial logistic regression analysis confirmed the independent predictive value of a country and perceived importance of test decision reflecting the views of significant others.

CONCLUSION

While many obstetricians and gynaecologists favour prenatal testing reflecting a parental choice, the extent to which their values may affect the likelihood that informed choice is realised, may vary across countries. The impact of these findings on patient autonomy is raised.
