Women's Experiences and Preferences for Service Delivery of Non-Invasive Prenatal Testing for Aneuploidy in a Public Health Setting: A Mixed Methods Study

Considering medical risk information and communicating values: A mixed-method study of women's choice in prenatal testing

Introduction

Nowadays, an important decision for pregnant women is whether to undergo prenatal testing for aneuploidies and which tests to uptake. We investigate the factors influencing women’s choices between non-invasive prenatal testing (NIPT) and invasive prenatal tests in pregnancies with elevated a priori risk of fetal aneuploidies.

Methodology

This is a mixed-method study. We used medical data (1st Jan 2015-31st Dec 2015) about women participating in further testing at Fetomaternal Medical Center at Helsinki University Hospital and employed Chi-square tests and ANOVA to compare the groups of women choosing different methods. Multinomial logistic regressions revealed the significant clinical factors influencing women’s choice. We explored the underlying values, beliefs, attitudes and other psychosocial factors that affect women’s choice by interviewing women with the Theory of Planned Behavior framework. The semi-structured interview data were processed by thematic analysis.

Results

Statistical data indicated that gestational age and counseling day were strong factors influencing women’s choice. Interview data revealed that women’s values and moral principles on pregnancy and childbirth chiefly determined the choices. Behavioral beliefs (e.g. safety and accuracy) and perceived choice control (e.g. easiness, rapidness and convenience) were also important and the major trade-offs happened between these constructs.

Discussion

Values are the determinants of women’s choice. Service availability and convenience are strong factors. Medical risk status in this choice context is not highly influential. Choice aids can be developed by helping women to identify their leading values in prenatal testing and by providing lists of value-matching test options and attributes.

Attitudes towards non-invasive prenatal diagnosis among obstetricians in Pakistan, a developing, Islamic country

OBJECTIVES

Stakeholders' views are essential for informing implementation strategies for non-invasive prenatal testing (NIPT). Little is known about such views in developing countries. We explored attitudes towards NIPT among obstetricians in Pakistan, a developing, Islamic country.

METHODS

A 35-item questionnaire was distributed and collected at eight events (a national conference and seven workshops in five cities) for obstetric professionals on advances in fetal medicine.

RESULTS

Responses from 113 obstetrician show positive attitudes towards implementation of NIPT: 95% agreed prevention of genetic conditions was a necessity, and 97% agreed public hospitals should provide prenatal screening tests. However, participants also agreed the availability of NIPT would increase social pressure on women to have prenatal screening tests and to terminate an affected pregnancy (53% and 63%, respectively). Most participants would not offer NIPT for sex determination (55%), although 31% would. The most valued aspects of NIPT were its safety, followed by its utility and then accuracy.

CONCLUSION

Participants generally supported the implementation of NIPT but raised concerns about social implications. Therefore, national policy is needed to regulate the implementation of NIPT, and pretest information and post-test genetic counselling are needed to mitigate social pressure and support parents to make informed decisions. © 2017 John Wiley & Sons, Ltd.

A qualitative study looking at informed choice in the context of non-invasive prenatal testing for aneuploidy

Objective

To explore women's attitudes towards non‐invasive prenatal testing (NIPT) and determine factors influencing their decisions around uptake of NIPT.

Method

We conducted qualitative interviews to assess knowledge, attitude and deliberation amongst women offered NIPT in a public health service. In total, 45 women took part in telephone interviews (79% participation rate).

Results

Most women could recount the key aspects of NIPT discussed during pre‐test counselling but had variable knowledge about Down syndrome. Analysis of women's attitudes towards undergoing NIPT revealed three dominant factors they considered when reflecting on the test: (1) how NIPT compared with alternative testing options, (2) reflections on coping and (3) moral or religious values. Exploring the deliberative process revealed the different paths women take when making decisions. For some, it was an extension of the decision to have Down syndrome screening; some considered it early on following the booking‐in appointment; others made step‐wise decisions about NIPT when it became relevant to them.

Conclusion

Our findings support the importance of personalised counselling, whereby women and their partners have the opportunity to reflect on the implications of the test results in the context of their own lives and values. Our data highlight the influence of personal circumstances on decision‐making. © 2016 The Authors. Prenatal Diagnosis published by John Wiley & Sons, Ltd.

What's Already Known About This Topic?

Non‐invasive prenatal testing (NIPT) for aneuploidies has entered clinical practice, although concerns exist around the potential for routinisation and erosion of informed choice.

Research into informed decision‐making for NIPT is now beginning to emerge, although these are predominantly quantitative studies.

What Does This Study Add?

Participants frequently used a combination of clinical information, personal experiences and moral values to guide action.

For many participants, decision‐making was a multistep deliberative process which occurred as and when new information became available.
