Expanded carrier screening in Flanders (Belgium): an online survey on the perspectives of nonpregnant reproductive-aged women

Exploring attitudes and experiences with reproductive genetic carrier screening among couples seeking medically assisted reproduction: a longitudinal survey study

PURPOSE

This study aimed to assess the attitudes and experiences of subfertile couples applying for medically assisted reproduction (MAR) using their own gametes towards reproductive genetic carrier screening (RGCS) for monogenic conditions.

METHODS

A prospective survey study was conducted where subfertile couples were recruited from the fertility centre of a university hospital in Flanders, Belgium. Participants were offered RGCS free of charge and completed self-administered questionnaires at three different time points.

RESULTS

The study sample consisted of 26 couples. Most participants had no children, did not consider themselves as religious, and had some form of higher education. Overall, attitudes towards RGCS were mostly positive and the intention to participate in RGCS was high. Anxiety scores were only elevated and clinically relevant for a limited number of participants. A large proportion of participants would consider preventive reproductive options like prenatal diagnosis or in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) combined with pre-implantation genetic testing for monogenic conditions (PGT-M) in the event of an increased likelihood of conceiving a child with a hereditary condition. Participants were satisfied with their decision to undergo RGCS, and the majority would recommend RGCS to other couples.

CONCLUSION

Our study findings suggest that subfertile couples applying for MAR using their own gametes find RGCS acceptable and have a positive attitude towards it. This study provides valuable insights into the perspectives of these couples, highlighting the need for appropriate counseling and timely information provision.

Experiences of nonpregnant couples after receiving reproductive genetic carrier screening results in Belgium

Reproductive genetic carrier screening (RGCS) allows for the identification of couples who have an increased likelihood of conceiving a child with a particular autosomal recessive or X-linked condition. The aim of this study was to assess the level of satisfaction, anxiety, knowledge retention, psychosocial and counseling-related aspects among couples who chose to have RGCS. Participants were initially informed about their screening results by telephone. After obtaining a written report of test results, participants were asked to complete an individual self-administered questionnaire. All participants (n = 67) felt they had enough information to make an informed choice. None of the participants regretted their choice to have RGCS. Test results were most often shared with parents (61%) or siblings (37%). Our findings demonstrate that the information/counseling and reporting strategy that was used in the context of this study led to high participant satisfaction, an increase in knowledge over time and favorable psychosocial and counseling-related outcomes.

Public willingness to participate in population DNA screening in Australia

Background

Population-based DNA screening for medically actionable conditions has the potential to improve public health by enabling early detection, treatment and/or prevention; however, public attitudes and willingness to participate in DNA screening have not been well investigated.

Methods

We presented a scenario to members of the Australian public, randomly selected from the electoral roll via the Australian Survey of Societal Attitudes, describing an adult population DNA screening programme currently under development, to detect risk of medically actionable cancers and heart disease. We asked questions regarding willingness to participate and pay, preferred delivery methods and concerns.

Results

We received 1060 completed questionnaires (response rate 23%, mean age 58 years). The vast majority (>92%) expressed willingness to undertake DNA screening. When asked about the optimal age of screening, most (56%) favoured early adulthood (aged 18–40 years) rather than at birth or childhood. Many respondents would prefer samples and data be kept for re-screening (36%) or research use (43%); some preferred samples to be destroyed (21%). Issues that decrease likelihood of participation included privacy (75%) and insurance (86%) implications.

Conclusion

Our study demonstrates public willingness to participate in population DNA screening in Australia, and identifies barriers to participation, to be addressed in the design of screening programmes. Results are informing the development of a pilot national DNA screening programme.

Exploring informed choice in preconception reproductive genetic carrier screening by using a modified Multidimensional Measure of Informed Choice

OBJECTIVES

To explore informed choice in reproductive genetic carrier screening (RGCS).

METHODS

Women visiting a gynaecologist practice in Flanders (Belgium) were asked to consider participation in a study where RGCS was offered for free to them and their male partner. A modified Multidimensional Measure of Informed Choice was used to determine whether couples who opted for RGCS made an informed choice. In addition, we assessed risk perception, feelings towards RGCS, anxiety and decisional conflict.

RESULTS

Most participants (82 %, n = 63/77) made an informed choice with regard to RGCS according to our modified MMIC. Thirteen participants made an uninformed choice due to insufficient knowledge and one participant because of insufficient knowledge and value-inconsistency. Anxiety scores were elevated for three participants. Two participants presented with decisional conflict.

CONCLUSION

Our results show high rates of informed choice among non-pregnant couples who were offered RGCS in a research study and received up to 30 min of pre-test counseling.

PRACTICE IMPLICATIONS

Limited resources outside a research context may impact informed choice. Pre-test counselling initiatives for RGCS should ideally be organized in such a way that information can be provided at multiple time points to avoid information overload and to allow for a reflection period.

Knowledge, attitudes and preferences regarding reproductive genetic carrier screening among reproductive-aged men and women in Flanders (Belgium)

Through carrier screening couples at-risk of conceiving a child with an autosomal recessive or X-linked condition can be identified prior to conception. The aim of this study was to assess knowledge, attitudes and preferences regarding reproductive genetic carrier screening (RGCS) among reproductive-aged men and women in Flanders (Belgium). Women and men of reproductive age visiting their pharmacist were invited to answer a self-administered questionnaire. Prior to filling in the questionnaire, participants were asked to read an information leaflet explaining some key concepts about RGCS. Our sample included 387 individuals of reproductive age, of which 68.5% were female and 31.5% were male. Most of the participants were below 34 years old (72.9%), didn't have children (68.6%) and were currently in a relationship (69.1%). Offering RGCS to couples that want to have children was found acceptable by 86% of participants. However, fewer participants would consider RGCS for themselves in the future (61%). We observed a positive correlation between attitude score/knowledge score and the intention to have RGCS. Half of the participants (50.9%) preferred the disclosure of individual test results. Most of participants indicated that RGCS should be offered through the gynecologist (81.1%), followed by the GP (71.5%) and the Centre for Human Genetics (64.8%). About 68.9% of participants were willing to pay out-of-pocket for an RGCS test. We recommend that RGCS should ideally be implemented through a tailored implementation strategy whereby individual needs and preferences can be taken into account.

Reasons affecting the uptake of reproductive genetic carrier screening among nonpregnant reproductive-aged women in Flanders (Belgium)

Reproductive genetic carrier screening (RGCS) allows to identify couples who have an increased likelihood of conceiving a child affected with an autosomal recessive or X-linked monogenic condition. Multiple studies have reported on a wide and fragmented set of reasons to accept or decline RGCS. Only a few studies have been performed to assess the uptake of RGCS. Nonpregnant women visiting their gynecologist were invited to complete a questionnaire assessing perceived susceptibility, the acceptability of offering RGCS, attitudes, the intention to participate in RGCS, reasons to accept or decline RGCS, and sociodemographic characteristics. Women who showed the intention to have RGCS were asked to consider a free RGCS offer. Most women (n = 127) were between 25 and 34 years old (60%), in a relationship (91%), and wanted to have children (65%). Study participants had positive attitudes towards RGCS and the intention to consider RGCS in the future. Reasons to accept RGCS were being able to share genetic information with children or relatives (n = 104/127, 82%), to prevent the birth of a child affected with a hereditary condition (n = 103/127, 81%), and/or to know the chance of conceiving a child with a hereditary condition (n = 102/127, 80%). Reasons for declining RGCS were the possible concerns that could arise when receiving test results (n = 27/127, 21%), having no family history of hereditary disorders (n = 19/127, 15%), and not wanting to take action based on test results (n = 13/127, 10%). Among test intenders that met the inclusion criteria, 53% decided to participate in RGCS together with their male reproductive partner. More in-depth research on the decision-making process behind the choice to accept or decline an RGCS offer would be highly valuable to make sure couples are making informed reproductive choices.
