Attitude changes toward prenatal testing among women with twin pregnancies after the introduction of noninvasive prenatal testing: A single-center study in Japan

Aim

This study aimed to evaluate changes in prenatal testing among women with twin pregnancies before and after the introduction of noninvasive prenatal testing (NIPT). To date, no consensus on prenatal testing for twin pregnancies has been reached in Japan.

Methods

Women pregnant with twins who requested prenatal testing at Kyushu Medical Center from 2005 to 2018 were included in this study. Genetic counseling was provided to all participants. Their chosen methods of testing were collected and classified as invasive diagnosis (ID), noninvasive screening (NIS), and no test requested (NR). Parity, chorionicity, and methods of conception were assessed as attributes. The study period was divided into three terms according to testing availability in our center.

Results

After NIPT was introduced in our center, the use of ID methods decreased and eventually disappeared while NIS came to the forefront. NR was also the preferred choice of women with twin pregnancies before the introduction of NIPT and decreased but did not disappear after introducing NIPT. Women with twin pregnancies who underwent assisted reproduction initially showed hesitation to undergo testing but showed a strong preference for NIS after the introduction of NIPT. Differences in choice according to parity, chorionicity, and methods of conception were found before the introduction of NIPT but disappeared after introducing NIPT.

Conclusion

Increasing information about NIPT has apparently influenced the attitudes of women with twin pregnancies to prenatal testing in Japan. In particular, those who conceive through assisted reproductive technologies exhibited a strong preference for NIPT.

Pregnant women's experiences of non-invasive prenatal testing (NIPT) in Japan: A qualitative study

In Japan, prenatal testing does not include a publicly insured routine health check-up for pregnant women. Hence, taking advantage of such prenatal testing procedures is still not an option for a majority of Japanese women. However, social support systems for children and adults with disabilities have been developed with the assumption that people with disabilities will continue receiving support from their family members, especially their mothers. In this study, we described pregnant women's experiences regarding noninvasive prenatal testing (NIPT) within the context of their physical experiences during the NIPT process, Japanese society, and their medical circumstances. Women with no family history of genetic diseases or fetal disabilities and who had also received negative results after the NIPT explanation were recruited. Altogether, 15 women participated in the biographical narrative interview. The data were subjected to reflexive thematic analysis and signified advanced age for pregnancy as a trigger for both the women's consideration regarding receiving NIPT and interventions from their families and social group members. Participants considered themselves as the main caretaker for the older adults and individuals with disabilities and thus were afraid of the multiple responsibilities inherent in this reality. They were also concerned about the impact on any other siblings if the baby had disabilities. In addition, participants encounter physical and mental changes during the timeframe of the NIPT processes. Hence, as their fetuses mature, the psychological bonds the women develop with them are constantly evolving, and participants with histories of miscarriages or possible miscarriages expressed concerned not only about the results of NIPT but also about the specific possibility of losing their child in any way. In conclusion, the continuous support of these women throughout the NIPT process and social efforts for the improvement of the welfare system for people with disabilities are required to utilize NIPT effectively.

Pregnant women's opinions toward prenatal pretest genetic counseling in Japan

In-person models of genetic counseling (GC) have been the common method in Japan for pregnant women to receive GC. However, recent increases in the number of pregnant women considering undergoing prenatal testing have made it challenging to retain individualized in-person care. To explore pregnant women’s opinions toward pretest GC models and the ideal time duration, a self-administered questionnaire survey was conducted for women at their first prenatal visit. A total of 114 valid respondents (93.4%) were included in the analyses. Of these, 80.7% of women preferred in-person GC, followed by classroom (9.6%), group (3.5%), and telegenetic-based GC (2.6%). Women with experience in undergoing prenatal testing significantly did not prefer in-person GC (p = 0.05). Sixty-two women (54.4%) preferred a duration of 15–29 min for pretest GC sessions, followed by 30–59 min (28.9%) and <15 min (14.9%). Women’s preference of ≥30 min in length was significantly associated with anhedonia, singleton pregnancies, acquaintance with people with trisomy 21, and awareness of prenatal testing. Women who were unaware of the need for agreement with the partner for prenatal testing and who did not know the average life expectancy of a trisomy 21 patient significantly preferred <15 min in length over other durations. While the majority of women preferred in-person GC for <30 min, their preferences varied by their background characteristics, experiences, attitudes, and knowledge. These findings will help establish a prenatal GC system offering a choice of GC models in Japan; however, further large-scale studies are needed to confirm these findings.

The composition and capacity of the clinical genetics workforce in high-income countries: a scoping review

As genetics becomes increasingly integrated into all areas of health care and the use of complex genetic tests continues to grow, the clinical genetics workforce will likely face greatly increased demand for its services. To inform strategic planning by health-care systems to prepare to meet this future demand, we performed a scoping review of the genetics workforce in high-income countries, summarizing all available evidence on its composition and capacity published between 2010 and 2019. Five databases (MEDLINE, Embase, PAIS, CINAHL, and Web of Science) and gray literature sources were searched, resulting in 162 unique studies being included in the review. The evidence presented includes the composition and size of the workforce, the scope of practice for genetics and nongenetics specialists, the time required to perform genetics-related tasks, case loads of genetics providers, and opportunities to increase efficiency and capacity. Our results indicate that there is currently a shortage of genetics providers and that there is a lack of consensus about the appropriate boundaries between the scopes of practice for genetics and nongenetics providers. Moreover, the results point to strategies that may be used to increase productivity and efficiency, including alternative service delivery models, streamlining processes, and the automation of tasks.
