To analyze variables affecting couples' decision making about prenatal cytogenetic diagnosis in patients with no access to legal termination of pregnancy (TOP).
Patients undergoing invasive prenatal diagnosis were anonymously surveyed after counseling and before the procedure. The questionnaire enquired about sociodemographic features, medical history, knowledge of and attitudes toward genetic testing and TOP.
Two genetic units distributed 372 questionnaires. Mean maternal age was 36 +/- 4 years. Access to prenatal genetic counseling was mainly patient's own initiative, or 'self-referral'. Most self-referred patients (87%) considered that 'receiving accurate information' was the main issue. Eighty-one per cent of all couples knew that TOP because of fetal anomalies was not legal. In case of a serious anomaly, 68.2% of patients would contemplate TOP, in spite of the risk of being exposed to an unsafe abortion.
In many countries, prenatal genetic testing is offered, but TOP is not available. In the present study, although most of the couples who decided to undergo prenatal genetic testing were aware of this, they still chose to perform prenatal diagnosis. The main reason given was to obtain reliable information about fetal condition. Finally, if a fetal chromosomal abnormality were detected, most of them would consider TOP.
分析在无法获得合法终止妊娠(TOP)的情况下,影响夫妇对产前细胞遗传学诊断决策的变量。
对接受侵入性产前诊断的患者在咨询后和手术前进行匿名调查。问卷询问了社会人口学特征、病史、对基因检测和TOP的了解及态度。
两个遗传单元发放了372份问卷。产妇平均年龄为36±4岁。获得产前遗传咨询主要是患者自己主动,即“自我转诊”。大多数自我转诊患者(87%)认为“获得准确信息”是主要问题。所有夫妇中有81%知道因胎儿异常而进行的TOP是不合法的。在出现严重异常的情况下,68.2%的患者会考虑TOP,尽管有面临不安全堕胎的风险。
在许多国家,提供产前基因检测,但无法进行TOP。在本研究中,尽管大多数决定进行产前基因检测的夫妇知道这一点,但他们仍选择进行产前诊断。给出的主要原因是获取有关胎儿状况的可靠信息。最后,如果检测到胎儿染色体异常,他们中的大多数会考虑TOP。
