Psychological responses to prenatal NTS counseling and the uptake of invasive testing in women of advanced maternal age

Should pretest genetic counselling be required for patients pursuing genomic sequencing? Results from a survey of participants in a large genomic implementation study

PURPOSE

We assessed the decision-making of individuals pursuing genomic sequencing without a requirement for pretest genetic counselling. We sought to describe the extent to which individuals who decline genetic counselling reported decisional conflict or struggled to make a decision to pursue genomic testing.

METHODS

We administered a 100-item survey to 3037 individuals who consented to the Return of Actionable Variants Empirical study, a genomic medicine implementation study supported by the National Institutes of Health (USA) eMERGE consortium. The primary outcomes of interest were self-reported decisional conflict about the decision to participate in the study and time required to reach a decision.

RESULTS

We received 2895 completed surveys (response rate=95.3%), and of these respondents 97.8% completed the decisional conflict scale in its entirety. A majority of individuals (63%) had minimal or no decisional conflict about the pursuit of genomic sequencing and were able to reach a decision quickly (78%). Multivariable logistic regression analyses identified several characteristics associated with decisional conflict, including lower education, lower health literacy, lower self-efficacy in coping, lack of prior experience with genetic testing, not discussing study participation with a family member or friend, and being male.

CONCLUSION

As genomic sequencing is used more widely, genetic counselling resources may not be sufficient to meet demand. Our results challenge the notion that all individuals need genetic counselling in order to make an informed decision about genomic sequencing.

Impacts of variants of uncertain significance on parental perceptions of children after prenatal chromosome microarray testing

OBJECTIVE

There are concerns regarding the potential harms in receipt of prenatal chromosome microarray (CMA) results, particularly variants of uncertain significance (VUS). We examined the influence that the return of genomic results had on parental well-being and perceptions of children's development.

METHODS

Parents (n = 138) of 83 children who underwent prenatal chromosomal microarray testing completed questionnaires assessing perception of children's development, parent-child attachment, parental mood, parenting competence, martial satisfaction, satisfaction with the decision to undergo testing, and attitudes about genetics at age 12 and/or 36 months. Responses were compared between parents who received normal/likely benign results and VUS results.

RESULTS

Compared to normal/likely benign results, parents who received VUS results rated their child as less competent on the BITSEA scale at 12 (β = -1.65, P = .04) though not 36 months (P = .43). There were no differences in parent mood, marital satisfaction, or parenting competence. At 36 months, parents in the VUS group reported less satisfaction with their decision to undergo genetic testing (β = 1.51, P = .02).

CONCLUSION

Chromosome microarray VUS results have limited impact on parental well-being and perception of children's development. However, the initial diminished perception of child competency and later dissatisfaction with genomic testing indicate the need to assist parents in coping with ambiguous results.

Psychological correlates of decision-making during prenatal diagnosis: a prospective study

OBJECTIVE

Decision-making during prenatal diagnosis has not been extensively studied. We aimed to determine psychological correlates and level of decisional conflict following prenatal diagnosis.

METHOD

A total of 159 pregnant women were consecutively enrolled. All participants completed three questionnaires (the Hospital Anxiety and Depression scale, the Berlin Social Support scales and the Decisional Conflict scale) at three time points (T1 - waiting period between prenatal testing and disclosure of the results; T2 - decision phase within 3 days from test result disclosure; T3 - digestion period within 3 weeks from disclosure).

RESULTS

Women with fetal anomaly who terminate pregnancy were significantly more anxious and depressed than controls at each time point. Additionally, women with a normal fetus who terminate pregnancy presented higher level of anxiety and depression compared with controls at T2. Women who terminated pregnancy showed increased uncertainty scores at T2 and T3. Anxious and depressed individuals at T2 (decision period) were more uncertain about their choice at T3 compared to women with normal levels of anxiety and depression.

CONCLUSION

The decision to terminate pregnancy, irrespective of test results, may determine emotional distress and psychiatric morbidity. Women who were anxious and depressed at decision appeared to be more uncertain about their choices as time passed by. A careful assessment of women during prenatal diagnosis should be useful to identify women who may benefit from psychological support.

A systematic review of factors influencing uptake of invasive fetal genetic testing by pregnant women of advanced maternal age

Women of advanced maternal age have a higher risk of having a child affected by a chromosomal disorder than younger childbearing women and are frequently offered invasive testing during pregnancy. The aim of our systematic review was to identify and analyse the current evidence base regarding factors that influence the uptake of invasive fetal testing by pregnant women of advanced maternal age. We conducted a systematic review. A search of The Cochrane Library, CINAHL, Embase and Medline databases was undertaken for papers published in English and Italian from January 2002 to May 2012. Eleven studies satisfied the inclusion criteria, were subjected to quality assessment and included in the review. We analysed the data using thematic analysis. The factors influencing women were classified as either external or psychosocial factors. External factors included the opportunity for screening, screening results and use of genetic counselling. Psychosocial factors related to ethnicity, socio-demographic status and attendance of partners during counselling. It is difficult to draw firm conclusions as to the principle factors that influence uptake of invasive tests by women of AMA. More research is needed to enhance understanding of relevant factors to ensure that services are offered in a way that acknowledges practical as well as psychosocial influences. This type of research will help to equip midwives and other professionals caring for women during pregnancy to ensure that women are supported to make the choices that are appropriate for them and their families.

Does an information film about prenatal testing in early pregnancy affect women's anxiety and worries?

OBJECTIVE

To explore if an information film about prenatal examinations affects pregnant women's worry and anxiety.

METHODS

Randomized controlled study. The intervention was an information film about prenatal examinations. Data was collected in gestational week 26 by a questionnaire including the STAI (State-Trait Anxiety Inventory) instrument and further questions about worry. A total of 184 women in the intervention group and 206 in the control group filled in the questionnaire.

RESULTS

There were no statistically significant differences between the groups neither in state nor trait anxiety. Regarding worry about the possibility of something being wrong with the baby and worry about giving birth, there were no statistically significant differences between the groups. The women stated that to see the film increased their worry rather than decreased it.

CONCLUSION

An informational film as additional information to complement written and verbal information about prenatal testing does not appear to increase women's anxiety and worries. However, the informational film may cause worry at the time of viewing which should be taken into consideration.

Invasive prenatal testing decisions in pregnancy after infertility

OBJECTIVE

This study assessed decisional conflict about invasive prenatal testing among women pregnant after infertility.

METHODS

We surveyed 180 pregnant women with a history of infertility using a mixed methods cross-sectional design. Difficulty in deciding whether to have prenatal testing was measured using the Decisional Conflict Scale.

RESULTS

A minority of women (31%) chose to have invasive prenatal testing. Most participants (72%) reported low decisional conflict (score < 25; mean = 22.1; standard deviation = 23.2; range: 0-100). Half (53%) of the participants said that infertility made the testing decision easier. Qualitative data suggest that infertility makes the decision easier by clarifying relevant values and priorities. Most infertility characteristics studied were not significantly associated with decisional conflict. Variables associated with higher decisional conflict included infertility distress due to rejection of a childfree lifestyle, disagreement with others about testing, and choosing to have invasive testing after having had treatment for infertility.

CONCLUSIONS

For some women, infertility may make the invasive prenatal testing decision easier. Women with the greatest need for decisional support were those who have had treatment and choose invasive testing, who disagree with others about their testing choice, or who are particularly distressed about being childless.

A systematic review of the impact of genetic counseling on risk perception accuracy

This review presents an overview of the impact of genetic counseling on risk perception accuracy in papers published between January 2000 and February 2007. The results suggest that genetic counseling may have a positive impact on risk perception accuracy, though some studies observed no impact at all, or only for low-risk participants. Several implications for future research can be deduced. First, future researchers should link risk perception changes to objective risk estimates, define risk perception accuracy as the correct counseled risk estimate, and report both the proportion of individuals who correctly estimate their risk and the average overestimation of the risk. Second, as the descriptions of the counseling sessions were generally poor, future research should include more detailed description of these sessions and link their content to risk perception outcomes to allow interpretation of the results. Finally, the effect of genetic counseling should be examined for a wider variety of hereditary conditions. Genetic counselors should provide the necessary context in which counselees can understand risk information, use both verbal and numerical risk estimates to communicate personal risk information, and use visual aids when communicating numerical risk information.

Anxiety levels in women undergoing prenatal maternal serum screening for Down syndrome: the effect of a fast reporting system by mobile phone short-message service

OBJECTIVE

To study the effect of fast reporting by mobile phone short-message service (SMS) on anxiety levels in women undergoing prenatal biochemical screening for Down syndrome.

METHOD

From January 2005 to December 2006, 2782 women undergoing prenatal biochemical serum screening were randomized into fast reporting by SMS (group A) or without mobile phone reporting (group B). Anxiety levels were measured with the Spielberger State-Trait Anxiety Inventory (STAI) before prenatal screen testing, before the appointed clinic (when the SMS report had already been given to group A), and 3 days after the appointed clinic (when the full screening report had been given to groups A and B).

RESULTS

For screen-negative women, anxiety scores did not differ between groups before prenatal screen testing and 3 days after the appointed clinic. The state-anxiety scores measured on the second occasion had declined significantly in group A. The state-anxiety scores in both groups increased over the 3-week period after being informed of positive screen results. The trait- and state-anxiety scores at all points did not differ between the two groups of screen-positive women.

CONCLUSIONS

The provision of a routine reporting system plus additional SMS report revealed some overall benefits in reducing anxiety among women with screen-negative result.

Tailoring peripartum nursing care for women of advanced maternal age

Births to women of advanced maternal age have increased dramatically over the last decade in both the United States. The majority of women who deliver their first baby after age 35 are healthy and experience positive birth outcomes. According to current research, primigravidas over 35 tend to be educated consumers. Their physical and psychosocial needs differ from those of the mother in her 20s, due to advanced age and factors related to difficulty conceiving and life circumstances. This paper presents (a) an overview of the possible risks to outcomes of childbearing for women over the age of 35; (b) a discussion of how women of advanced maternal age may differ from younger women related to developmental stage, stress or anxiety or both, decision making, and support systems; and (c) an exploration of tailoring nursing care strategies during the peripartum period specifically for this age cohort.

A report of two linked studies of knowledge and attitudes to prenatal screening and testing in adults of reproductive age in Japan and the UK

BACKGROUND

prenatal screening for fetal abnormality is being offered routinely in many countries. The need for informed consent demands that the nature of screening is understood by prospective parents, but the opportunities for providing information early in pregnancy before decision-making may be limited.

OBJECTIVE

to assess the knowledge about, and attitudes to, prenatal screening in adults of reproductive age in two countries.

DESIGN

two groups of adults were surveyed using a specifically designed tool to assess knowledge about fetal abnormalities and potential screening tests, attitudes to screening and termination of pregnancy, and information required by parents before making decisions.

SETTING AND PARTICIPANTS

90 participants were surveyed in Japan, 72% of whom were pregnant or had a partner who was pregnant; 93 participants were surveyed in the UK, none of whom were pregnant. All respondents were aged between 18 and 45 years.

MEASUREMENTS

demographic data were collected and analysed. Frequencies were calculated for each questionnaire response. A series of t-tests and chi(2) tests were used to assess differences between the two groups. Free-text data were analysed using content analysis.

FINDINGS

overall knowledge of prenatal tests and the conditions for which screening is offered was low in both groups. Significant differences exist between the perception of the conditions for which screening or testing can be offered and the types of conditions that can actually be detected prenatally. Most respondents in both countries would consider termination of pregnancy for fetal abnormality. The information most frequently cited by respondents as important when deciding about testing were the chances of damage to the health of fetus, mother, or both.

KEY CONCLUSIONS

women and men of reproductive age in the groups studied are not well-prepared to make decisions about screening or testing in pregnancy.

IMPLICATIONS FOR PRACTICE

improvements in preconceptual education on prenatal screening and testing may be required to ensure prospective parents can make informed decisions in early pregnancy.

Nuchal translucency screening and anxiety levels in pregnancy and puerperium

OBJECTIVES

To compare levels of anxiety and depression during pregnancy and puerperium between women who are offered nuchal translucency (NT) screening routinely and those who are not, and to compare levels between women accepting and those declining screening.

METHODS

In 12 midwife practices in three different health districts an experimental NT screening program was offered to pregnant women between 1 June 1999 and 1 January 2001. As part of this implementation study, questionnaires including the Hospital Anxiety and Depression Scale (HADS) were completed: after the patient was informed but before screening (T1), at 20 weeks of gestation (T2), and 6 weeks after delivery (T3). A control group of women receiving routine prenatal care (i.e. no screening offered) also completed the HADS questionnaire at 12 and 20 weeks and after delivery.

RESULTS

Five hundred and twenty-seven questionnaires were analyzed. There was a screening uptake of 87% in the intervention group (i.e. those offered screening). Women in this group differed significantly in the percentage of previous miscarriages and religious background compared with the control group. We adjusted for these differences in the analysis. There were no significant differences in HADS scores between the intervention and the control groups at T1, suggesting that women receiving information on screening were not more anxious compared with women who were not informed. Women who were offered screening (acceptors as well as decliners) had significantly lower HADS levels at 20 weeks and after delivery. There were no demographic differences between women accepting and those declining screening.

CONCLUSION

Informing women and offering them NT screening for Down syndrome does not increase anxiety or depression levels in pregnancy. In fact, women undergoing or declining screening seem less anxious compared with those who are not offered screening. It is possible that informing women and offering them the chance to decide autonomously whether to participate in screening reduces anxiety levels.

Does prenatal screening influence anxiety levels of pregnant women? A longitudinal randomised controlled trial

OBJECTIVES

Questions addressed are: (1) Does offering prenatal screening increase anxiety? (2) Does receiving a negative screening result make women less anxious and does a positive screening result make women more anxious? (3) What are the long-term consequences on anxiety of offering screening and receiving a screening result?

METHODS

Women were offered prenatal screening or no screening in a randomised controlled trial. State anxiety (STAI) and child-related anxiety (PRAQ-R) were measured. Questionnaires were filled in before prenatal screening was offered (T1), after the offer (T2), after the test result (T3), and in the third trimester of pregnancy (T4).

RESULTS

Child-related anxiety levels were higher in women who chose to be screened compared to women who declined screening. Offering prenatal screening did not lead to increased anxiety levels. General anxiety increased in positively screened women, but decreased later in pregnancy. Women who were negatively screened or declined screening scored lower than the control group.

CONCLUSION

For most women, offering prenatal screening and receiving the test result do not adversely affect anxiety. Giving pregnant women a choice to have prenatal screening done seems to have a small favourable effect on general feelings of anxiety.

Development of an audit tool for genetic services

Rapid growth in demand and altered professional roles have produced changes in the delivery of genetic services over the past decade, but these have not been rigorously evaluated because of the paucity of appropriate audit tools. The aim of this study was to use clients' accounts and factor analysis to develop a robust assessment and audit tool. Qualitative data abstracted from several published studies were used to generate a number of statements related to outcomes of genetic services. A total of 57 statements were incorporated into a questionnaire. The questionnaire was mailed to clients of the Wales genetic service (n = 133) who had completed their episode of care. Respondents were asked to rank each statement on a seven-point Likert type scale. Responses were subjected to factor analysis. A total of 97 anonymized responses were received (73% response rate). Six main factors were found to contribute to the outcome of the service from the client's perspective. These were labeled (i) enhanced understanding, (ii) positive psychological change, (iii) respect for autonomy, (iv) adaptation, (v) disequilibirium, and (vi) value of contact. The audit tool has now been refined for use in evaluating genetic services. Questions are included to investigate the six outcome areas shown to be relevant from the client's perspective. Data from the next phase of the study will be analyzed to validate the tool for use in both clinical audit and research contexts.
