Decision aids for prenatal testing: A systematic review and meta-analysis

"We will be the ones bearing the consequences": A qualitative study of barriers and facilitators to shared decision-making in hospital-based maternity care

BACKGROUND

Pregnant women involved in decisions about their care report better health outcomes for themselves and their children. Shared decision-making (SDM) is a priority for health services; however, there is limited research on factors that help and hinder SDM in hospital-based maternity settings. The purpose of this study was to explore barriers and facilitators to SDM in a large tertiary maternity care service from the perspectives of multiple stakeholders.

METHODS

Qualitative semi-structured interviews were undertaken with 39 participants including women, clinicians, health service administrators and decision-makers, and government policymakers. The interview guide and thematic analysis were based on the Theoretical Domains Framework to identify barriers and facilitators to SDM.

RESULTS

Women expect to be included in decisions about their care. Health service administrators and decision-makers, government policymakers, and most clinicians want to include them in decisions. Key barriers to SDM included lack of care continuity, knowledge, and clinician skills, as well as professional role and decision-making factors. Key facilitators pertained to policy and guideline changes, increased knowledge, professional role factors, and social influences.

CONCLUSION

This study revealed common barriers and facilitators to SDM and highlighted the need to consider perspectives outside the patient-clinician dyad. It adds to the limited literature on barriers and facilitators to SDM in hospital care settings. Organizational- and system-wide changes to service delivery are necessary to facilitate SDM. These changes may be enabled by education and training, changes to policies and guidelines to include and support SDM, and adequately timed information provision to enable SDM conversations.

Informal Prenatal Genetic Screening Education: What can you learn from Google and YouTube?

Introduction

The goal of this paper is to explore what online education and decision support tools are freely available to patients about prenatal screening.

Materials and Methods

We 1) conducted an environmental scan using Google Trends to identify and evaluate prenatal screening search terms, 2) created a list of websites and YouTube videos that would be easily accessed by a searcher and 3) characterized the information within those websites and videos, including an examination of their qualities as a decision support tool and a readability analysis.

Results

Fifty websites, containing 62 unique educational resources, and 39 YouTube videos were analyzed. The websites were primarily educational, though the education was provided by a range of sources including non-profit and for-profit organizations, universities, and governments (i.e., public health departments). Readability scores (PEMAT-P) for the sites ranged from 50% to 92%, with a median score of 74%. Two of the websites we evaluated met all of the limited decision support standards we applied; four of the websites included patient stories or experiences and eight included some element of values clarification. Videos were more likely to include values clarification.

Discussion

The information available to patients online is variable. While most is balanced and informative, much is difficult to read and missing key decision-making factors. Healthcare providers should work with patients to ensure they have basic comprehension of the prenatal genetic screening materials, possible result outcomes, and expected steps following a positive screening result.

Effects of an animated educational video on knowledge of cell-free DNA screening among Thai pregnant women: a randomized control trial

BACKGROUND

In developing countries, pregnant women have insufficient knowledge about cell-free DNA screening. Reports from developed countries have found that various tools in prenatal genetic counseling can improve the knowledge of pregnant women who undergo cell-free DNA screening. Data are limited from developing countries where women have different baseline socio-educational backgrounds. The objective of this study was to compare the effects of an animated educational video combined with traditional counseling versus traditional counseling alone in changing pregnant women's knowledge of cell-free DNA screening.

METHODS

This study was a randomized control trial at an antenatal clinic. Eligible subjects who were Thai pregnant women, were randomized to either view or not view the 4-minute animated educational video explaining cell-free DNA screening. Both groups received traditional counseling. The women were asked to complete a Thai questionnaire assessing knowledge of the screening before and after intervention. The questionnaire consisted of three sections: demographic data of the research participants and their existing awareness about cell-free DNA testing; performance and limitations of cell-free DNA screening; and participants' attitudes toward the positive screening. Primary outcome was the change in knowledge scores. Secondary outcomes were attitudes toward positive screening test, levels of satisfaction with counseling, and screening acceptance rates.

RESULTS

Data from 83 women in the video group and 82 in the non-video group were analyzed. The knowledge score (range 0-18) change after counseling was significantly higher in the video group than the non-video group (+ 7.1 ± 3.3 vs + 4.2 ± 2.5; p = 0.03). There were no significant differences in attitudes toward positive screening test (p = 0.83), levels of satisfaction (p = 0.24), or screening acceptance rates (p = 0.15) between the groups.

CONCLUSIONS

Adding the video to traditional counseling was better than traditional counseling alone in improving pregnant women's knowledge about cell-free DNA screening.

TRIAL REGISTRATION

The study was retrospectively registered with the Thai Clinical Trials Registry (TCTR20210917001, 17/09/2021).

The effects of decision aids for genetic counselling among people considering genetic testing: A systematic review

AIM

To assess the effectiveness of decision aids for genetic counsellees to improve their conflicts in decision-making and psychological well-being when considering genetic tests for inherited genetic diseases, and their knowledge about these tests and their genetic risks.

DESIGN

Systematic review.

DATA SOURCES

Six electronic databases (PubMed, MEDLINE, OVID Nursing, APA PsycINFO, EMBASE and CINAHL) were searched from inception to May 2022.

REVIEW METHODS

Only randomised controlled trials that examined the effect of decision aids for information provision centring genetic testing on outcomes including decisional conflicts, informed choice making, knowledge on genetic risks or genetic tests, and psychological outcomes among participants who had undergone genetic counselling were included. Their risk of bias was assessed using the Version 2 of the Cochrane risk of bias tool for randomised trials. Results were presented narratively. The review was conducted according to the PRISMA checklist.

RESULTS

Eight included studies examined the effect of booklet-based, computer-based, film-based or web-based decision aids on individuals considering genetic testing for their increased cancer risks. Despite contrasting findings across studies, they showed that decision aids enable genetic counsellees to feel more informed in decision-making on genetic tests, although most showed no effect on decisional conflict. Knowledge of genetic counsellees on genetic risks and genetic tests were increased after the use of decision aids. Most studies showed no significant effect on any psychological outcomes assessed.

CONCLUSIONS

Review findings corroborate the use of decision aids to enhance the effective delivery of genetic counselling, enabling genetic counsellees to gain more knowledge of genetic tests and feel more informed in making decisions to have these tests.

RELEVANCE TO CLINICAL PRACTICE

Decision aids can be used to support nurse-led genetic counselling for better knowledge acquisition and decision-making among counsellees.

Preconception education program for non-invasive prenatal testing focused on interest in genetics among female university students in Japan: a quasi-experimental study comparing pre-intervention, post-intervention, and three-month follow-up results

BACKGROUND

Non-invasive prenatal testing (NIPT) is offered as a reproductive choice in many countries. However, pregnant women, particularly those who are primipara or lack knowledge of prenatal testing, experience difficulties understanding adequate information and making decisions on NIPT. This study developed a preconception education program about NIPT, focusing on interest in genetics, and aimed to clarify the effectiveness of the program to help women make decisions on future NIPT.

METHODS

This was a one-group, quasi-experimental, pre-post-test study. The study population was female undergraduate students in Japan who participated in the education program. This program included two games and was based on the Attention, Relevance, Confidence, and Satisfaction (ARCS) model, which is an instructional design that stimulates learning interest and motivation. The data of 73 pre-pregnant women who completed all three questionnaires-before, immediately after, and three months after the intervention-were analyzed to clarify the time effects. Moreover, all variables were analyzed using logistic regression analysis to investigate factors related to decisional conflict.

RESULTS

Interest in genetics, knowledge of genetics and prenatal testing, and indecisive attitudes toward NIPT significantly improved immediately after the intervention, and consequently, these changes and reduction of decisional conflict were maintained at three months. Moreover, low decisional conflict at follow-up was significantly associated with a high interest in genetics (adjusted odds ratio, 3.42).

CONCLUSIONS

These findings provide preliminary evidence that this preconception education program, which focused on facilitating interest in genetics, assists pre-pregnant women to reduce decisional conflict about future NIPT.

TRIAL REGISTRATION

The trial was registered at the UMIN-CTR registry (January 16, 2023), registration number UMIN000050047.

Understanding the experiences and perspectives of prenatal screening among a diverse cohort

INTRODUCTION

Rapid advances in prenatal genetic screening technology make it difficult for providers to deliver adequate prenatal counseling. The aim of this study was to understand how prenatal screening educational approaches can meet the needs of patients.

METHODS

Qualitative content analysis was conducted on a diverse population who were interviewed to explore their perceived experiences and preferences for prenatal screening educational delivery.

RESULTS

Twenty-two women from three US sites were interviewed. Participants were racially/ethnically diverse with 22.7% identifying as Black or African American (n = 5), 40.9% as Hispanic (n = 9), and 4.5% as Pacific Islander (n = 1). Four themes were identified: prenatal screening education, prenatal screening decision-making, return of results, and suggestions for creating a decision aid. Most results were consistent with previous research not targeting a diverse population.

DISCUSSION/CONCLUSION

Our results indicate that learning style preferences vary between patients and that current methods are not consistently satisfying patient's desire for understanding, particularly with 'high-risk' results, suggesting that a standardized tool could improve knowledge and decrease decisional conflict. This diverse cohort suggested a list and description of each of the testing options offered, information about each condition being screened for, a timeline for the testing and return of results, costs associated, and non-technical language.

Co-designing a theory-informed intervention to increase shared decision-making in maternity care

BACKGROUND

Shared decision-making (SDM) has been shown to improve healthcare outcomes and is a recognized right of patients. Policy requires health services to implement SDM. However, there is limited research into what interventions work and for what reasons. The aim of the study was to develop a series of interventions to increase the use of SDM in maternity care with stakeholders.

METHODS

Interventions to increase the use of SDM in the setting of pregnancy care were developed using Behaviour Change Wheel and Theoretical Domains Framework and building on findings of an in-depth qualitative study which were inductively analysed. Intervention development workshops involved co-design, with patients, clinicians, health service administrators and decision-makers, and government policy makers. Workshops focused on identifying viable SDM opportunities and tailoring interventions to the local context (the Royal Women's Hospital) and salient qualitative themes.

RESULTS

Pain management options during labour were identified by participants as a high priority for application of SDM, and three interventions were developed including patient and clinician access to the Victorian Government's maternity record via the patient portal and electronic medical records (EMR); a multi-layered persuasive communications campaign designed; and clinical champions and SDM simulation training. Factors identified by participants for successful implementation included having alignment with strategic direction of the service, support of leaders, using pre-standing resources and workflows, using clinical champions, and ensuring equity.

CONCLUSION

Three interventions co-designed to increase the use of SDM for pain management during labour address key barriers and facilitators to SDM in maternity care. This study exemplifies how health services can use behavioural science and co-design principles to increase the use of SDM. Insights into the co-design of interventions to implement SDM in routine practice provide a framework for other health services, policy makers and researchers.

Does an educational video for aneuploidy screening improve informed choice among pregnant women? A randomised controlled trial

BACKGROUND

Poor knowledge and the lack of deliberation have been cited as reasons for women making uninformed choices about aneuploidy screening. Adequate pre-test counselling is of particular importance where non-invasive prenatal screening (NIPS) is being increasingly offered as a primary screening test.

DESIGN

Women attending the antenatal clinic with a singleton pregnancy below 14 weeks were randomised to receive routine counselling or the intervention-a 16-min educational video on aneuploidy screening before their consult. The primary outcome, rate of informed choice, was assessed using an adapted multidimensional measure of informed choice questionnaire, where informed choice was defined as good knowledge and value-consistent behaviour. Secondary outcomes included informed choice with deliberation, decisional conflict and anxiety.

RESULTS

Two hundred and eighty-six women were recruited. 69.8% of women in the intervention group made an informed choice compared with 53.6% in the control group (Risk Ratio [RR] 1.30, p = 0.014). A significantly higher number of women in the intervention group had good knowledge compared to controls (81% vs. 60.9%; RR 1.33, p = 0.001). Decisional conflict did not differ between groups, but women in the intervention group had higher anxiety scores (p < 0.001).

CONCLUSION

The study intervention was effective in helping women make informed choice. Qualitative studies to determine the reason for increased anxiety are needed.

Do online decision aids reflect new prenatal screening and testing options? An environmental scan and content analysis

Objective

Decision aids have been developed to help prospective parents make informed, shared decisions about medical tests, but these options are rapidly changing. This study aimed to identify and evaluate publicly available decision aids written in English for prospective parents seeking prenatal test information.

Methods

A systematic review process was followed using 3 sources: known decision aid repositories, fetal medicine organisations and Google. The search, screening process, quality assessment, and data extraction was performed by two independent researchers. The quality assessment of the decision aids was based on the International Patient Decision Aids Standards (IPDAS v.4.0).

Results

We identified 13 decision aids, which varied in the screening and diagnostic tests that they discussed. No decision aid met all the IPDAS v.4.0. criteria and no decision aid reported updated risk of miscarriage for amniocentesis and chorionic villus sampling (CVS). There was a lack of decision aids for some common decisions in the prenatal context.

Conclusion

We identified outdated content in current prenatal decision aids. The findings will inform healthcare professionals of the quality of current prenatal decision aids, which may facilitate their patients' informed decision-making about prenatal tests.

Innovation

Considerations for improving future decision aids are outlined.

Informed choice of pregnant women regarding noninvasive prenatal testing in Korea: a cross-sectional study

PURPOSE

This study explored the degree to which pregnant women in Korea made informed choices regarding noninvasive prenatal testing (NIPT) and investigated factors influencing whether they made informed choices.

METHODS

In total, 129 pregnant women in Korea participated in a web-based survey. Multidimensional measures of informed choice regarding NIPT and decisional conflict were used to measure participants' levels of knowledge, attitudes, deliberation, uptake, and decisional conflict related to NIPT. Additional questions were asked about participants' NIPT experiences and opinions.

RESULTS

All 129 pregnant women were recruited from an online community. Excluding those who expressed neutral attitudes toward NIPT, according to the definition of informed choice used in this study, only 91 made an informed choice (n=63, 69.2%) or an uninformed choice (n=28, 30.8%). Of the latter, 75.0% had insufficient knowledge, 39.3% made a value-inconsistent decision, and 14.3% did not deliberate sufficiently. No difference in decisional conflict was found between the two groups. A significant difference was found between the two groups in the reasons why NIPT was introduced or recommended (p=.021). Multiple logistic regression analysis showed that pregnant women who were knowledgeable (odds ratio [OR], 4.77; 95% confidence interval [CI], 2.17- 10.47) and deliberated (OR, 0.74; 95% CI, 0.57-0.98) were significantly more likely to make an informed choice.

CONCLUSION

The results of this study help healthcare providers, including nurses in maternity units, understand pregnant women's experiences of NIPT. Counseling strategies are needed to improve pregnant women's knowledge of NIPT and create an environment that promotes deliberation regarding this decision.

Midwives' empathy and shared decision making from women's perspective - sensitivity of an assessment to compare quality of care in prenatal and obstetric care

Background

For quality-oriented evaluation of prenatal and obstetric care, it is important to systematically consider the perspective of the women receiving care in order to comprehensively assess and optimize quality in a woman-centered manner. Empathy and Shared Decision Making (SDM) are essential components of woman-centered midwifery care. The aim of the study was to analyze measurement invariance of the items of the Consultation and Relational Empathy (CARE) and Shared Decision Making-Questionnaire (SDM-Q-9) scales depending on the prenatal versus obstetric care setting.

Methods

One hundred fifty women retrospectively assessed aspects of woman-centered midwifery care in both prenatal and obstetric care setting. The birth of the child was a maximum of 12 months ago. A structural equation modelling approach was adopted to separate true effects from response shift (RS) effects depending on care setting. The latter were analyzed in terms of recalibration (changing women’s internal measurement standards), Reprioritization (changing associations of items and construct) as well as Reconceptualization (redefining the target construct).

Results

A response shift model was identified for both assessments (pregnancy/birth: CFI = .96/.96; SRMR = .046/.051). At birth, both scales indicated lower quality of care compared with prenatal care (SDM-Q-9-M/CARE-8-M:|d| = 0.190/0.392). Although no reconceptualization is required for the items of both scales, RS effects are evident for individual items. Due to recalibration and reprioritization effects, the true differences in the items are partly underestimated (SDM-Q-9-M/CARE-8-M: 3/2 items) or overestimated (4/2 items).

Conclusion

The structure of the constructs SDM and Empathy, indicating woman-centered midwifery care, are moderated by the care settings. To validly assess midwives’ empathy and shared decision making from women’s perspective, setting-dependent response shift effects have to be considered. The proven item-specific response effects contribute to a better understanding of construct characteristics in woman-centered care by midwives during pregnancy and childbirth.

Exploring women's experiences of participation in shared decision-making during childbirth: a qualitative study at a reference hospital in Spain

BACKGROUND

Women's engagement in healthcare decision-making during childbirth has been increasingly emphasised as a priority in maternity care, since it increases satisfaction with the childbirth experience and provides health benefits for women and newborns. The birth plan was developed as a tool to facilitate communication between health professionals and women in Spain, but their value in routine practice has been questioned. Besides, little is known about women's experiences of participation in decision-making in the Spanish context. Thus, this study aimed to explore women's experiences of participation in shared decision-making during hospital childbirth.

METHODS

An exploratory qualitative study using focus groups was carried out in one maternity unit of a large reference hospital in Barcelona, Spain. Participants were first-time mothers aged 18 years or older who had had a live birth at the same hospital in the previous 12 months. Data collected were transcribed verbatim and analysed using a six-phase inductive thematic analysis process.

RESULTS

Twenty-three women participated in three focus groups. Three major themes emerged from the data: "Women's low participation in shared decision-making", "Lack of information provision for shared decision-making", and "Suggestions to improve women's participation in shared decision-making". The women who were willing to take an active role in decision-making encountered barriers to achieving this and some women did not feel prepared to do so. The birth plan was experienced as a deficient method to promote women's participation, as health professionals did not use them. Participants described the information given as insufficient and not offered at a timely or useful point where it could aid their decision-making. Potential improvements identified that could promote women's participation were having a mutually respectful relationship with their providers, the support of partners and other members of the family and receiving continuity of a coordinated and personalised perinatal care.

CONCLUSION

Enhancing women's involvement in shared decision-making requires the acquisition of skills by health professionals and women. The development and implementation of interventions that encompass a training programme for health professionals and women, accompanied by an effective tool to promote women's participation in shared decision-making during childbirth, is highly recommended.
