ObjectivePhysicians' attitudes and adoption behavior toward the delivery of prenatal tests take vital significance for its influence on their professional practice and patient acceptance. This study aimed to identify how physicians have perceived the diffusion of non-invasive prenatal testing (NIPT) in China.MethodsA cross-sectional study was conducted from July 2016 to October 2016 in Shanghai, and Fujian and Sichuan Provinces in China. Physicians working on prenatal screening completed a self-report questionnaire. Following Roger's diffusion of innovation model, multivariable logistic regressions were performed separately for the following key elements of the theory which influence diffusion: physician-perceived attributes of NIPT, communication channels, the nature of the social system, the extent of change agent (who introduces innovations into a society), promotion efforts, and physicians' benefits from adopting NIPT.ResultsMost specialists had a positive attitude (53.2 percent) toward NIPT, whereas 58.9 percent of physicians had already adopted NIPT in their clinical practice. Physician adoption of NIPT was positively associated with the strength of HTA evidence (p = .03), perceived communication frequency with colleagues (p = .04), adoption by other physicians (p = .07), hospital competition (p = .06), hospital teaching status (p = .02), perceived for-profit genetic testing company's promotion (p < .001), and perceived clinical practice skill improvement (p = .02). However, the adoption behavior toward NIPT may be negatively associated with physician-perceived ethical concerns of NIPT (p = .06).ConclusionObstetricians and gynecologists’ positive perceptions facilitate the adoption of NIPT. Combined with cost-effectiveness analysis of prenatal screening methods, health policy makers can promote the adoption of appropriate, cost-effective prenatal screening in pregnant women.

Abstract Background Non-invasive prenatal testing (NIPT) has revolutionized the prenatal screening landscape with its high accuracy and low false positive rate for detecting Trisomy 21, 18 and 13. Good understanding of its benefits and limitations is crucial for obstetricians to provide effective counselling and make informed decisions about its use. This study aimed to evaluate obstetrician knowledge and attitudes regarding NIPT for screening for the common trisomies, explore how obstetricians integrated NIPT into first-line and contingent screening, and determine whether expanded use of NIPT to screen for sex chromosome aneuploidies (SCAs) and microdeletion/microduplication syndromes (CNVs) was widespread. Methods A questionnaire was designed and administered with reference to the CHERRIES criteria for online surveys. Doctors on the Obstetrics & Gynaecology trainee and specialist registers were invited to participate. Medians and 95% confidence intervals (CI) were reported for confidence and knowledge scores. Results 94/306 (30.7%) doctors responded to the survey. First trimester screening (FTS) remained the main method offered to screen for the common trisomies. 45.7% (43/94) offered NIPT as an alternative first-line screen for singletons and 30.9% (29/94) for monochorionic diamniotic twins. A significant proportion offered concurrent NT and NIPT (25/94, 26.6%), or FTS and NIPT (33/94, 35.1%) in singletons. Varying follow up strategies were offered at intermediate, high and very-high FTS risk cut-offs for Trisomy 21. Respondents were likely to offer screening for SCAs and CNVs to give patients autonomy of choice (53/94, 56.4% SCAs, 47/94, 50% CNVs) at no additional cost (52/94, 55.3% SCAs, 39/94, 41.5% CNVs). Median clinical knowledge scores were high (10/12) and did not differ significantly between specialists (95% CI 10–11) and non-specialists (95% CI 9.89–11). Lower scores were observed for scenarios in which NIPT would be more likely to fail. Conclusions Our findings show the diversity of clinical practice with regard to the incorporation of NIPT into prenatal screening algorithms, and suggest that the use of NIPT both as a first-line screening tool in the general obstetric population, and to screen for SCAs and CNVs, is becoming increasingly prevalent. Clear guidance and continuing educational support are essential for providers in this rapidly evolving field.

Abstract Background: Although a variety of non-invasive techniques are used for prenatal genetic screening and diagnosis, our knowledge remains limited regarding the relationship between high-risk prenatal indications and fetal chromosomal abnormalities.Methods: We retrospectively investigated the prenatal genetic screening and karyotype analysis results of pregnant women who had undergone invasive prenatal testing in Prenatal Diagnosis Department of Meizhou People’s Hospital during Jan. 1, 2015 to Dec. 31, 2019. We analyzed the frequencies of chromosome abnormalities in women with high-risk indications.Results: A total of 2,193 pregnant women who had underwent invasive prenatal testing were included in our analysis. Chromosomal abnormalities occurred in 10.3% of these women, and rate increased with maternal age (P < 0.001). The frequencies of chromosome abnormalities varied for women with different high-risk indications, which was 10.3% (226/2193) for abnormal ultrasound results, 3.3% (31/938) for positive serum screening test results, 61.4% (78/127) for positive NIPT results, 9.3% (13/140) for AMA and 11.1% (10/90) for obstetric/family history. Follow up data showed that 380 pregnant women opted for termination the pregnancy, including 211 (55.5%) due to karyotype abnormalities and 169 (45.5%) due to abnormal ultrasonic outcomes.Conclusion: Our data suggested that the prenatal screening methods have high false positive rates. NIPT is the most accurate non-invasive prenatal screening. Apart from karyotype abnormality, abnormal ultrasound results alone accounted for a big part of pregnancy termination.

Non-invasive prenatal testinging (NIPT) is a relatively new method aimed at detecting fetal chromosomal aneuploidies by analyzing extracellular fetoplacental DNA in the blood of a pregnant woman. NIPT has high sensitivity and specificity, and many professional communities now recommend its use as a screening method. Since its introduction into clinical practice in Hong Kong in 2011, NIPT has expanded rapidly around the world. The experience of various countries in organizing non-invasive prenatal testing is described in this article. Key words: NIPT, non-invasive prenatal testing, extracellular fetoplacental DNA, prenatal screening, prenatal diagnosis, invasive prenatal diagnosis, aneuploidy

Fetal aneuploidies are among the most common causes of miscarriages, perinatal mortality and neurodevelopmental impairment. During the last 70 years, many efforts have been made in order to improve prenatal diagnosis and prenatal screening of these conditions. Recently, the use of cell-free fetal DNA (cff-DNA) testing has been increasingly used in different countries, representing an opportunity for non-invasive prenatal screening of pregnant women. The aim of this narrative review is to describe the state of the art and the main strengths and limitations of this test for prenatal screening of fetal aneuploidies.

IntroductionBirth defects seriously affect children's survival and quality of life and bring great suffering and financial burden to children and their families. Down's syndrome is one of the most common birth defects. Compared with traditional serological screening methods, non-invasive prenatal testing (NIPT) has higher sensitivity and specificity in the screening of Down's syndrome. In April 2017, the People's Government of Fuyang City, Anhui Province launched a NIPT free screening program. From the perspective of the beneficiary, this research investigated the awareness, willingness to pay and satisfaction of pregnant women in Fuyang City, Anhui Province, to better improve the use of NIPT.MethodsA questionnaire survey was conducted on 1,221 pregnant women who experienced this program in Fuyang City, Anhui Province. Multivariate ordered logistic regression models were established to analyze the factors affecting the satisfaction of NIPT.ResultsA total of 1,217 valid questionnaires were collected. Research indicated 82.5 percent knew about NIPT and 81.9 percent were willing to pay personally when its price was CNY 800 (USD 113.88) per test among pregnant women. The satisfaction of pregnant women with NIPT showed that the waiting time for test results was relatively low (4.5 out of 5 points) compared with other aspects of satisfaction. The higher the education level of the pregnant women, the lower their satisfaction with NIPT.ConclusionsIt is necessary to pay attention to the characteristics of education and to improve the awareness and satisfaction of NIPT among pregnant women. Meanwhile, if it is affordable enough for NIPT services to be provided by the government, this mode should be promoted. In conjunction with the willingness to pay of pregnant women, NIPT payment methods should be developed appropriately.

No field in obstetrics has seen such fast advancement, as the field of prenatal screening and diagnosis. A wide variety of tests are available today, and this at times becomes confusing both for the patient and the treating doctor that which screening test would be best suited in the given circumstances. Non-invasive prenatal screening, with its numerous advantages is rapidly becoming the test of first choice, especially in the affording set of population.  Although, the test has a very high sensitivity and a very good positive predictive value, this too suffers from some disadvantages which should be clear to the obstetrician ordering the test. A good knowledge about the test, the ideal target population in which this should be offered as the primary screening tool and limitations of the test should be known to all practicing obstetricians and primary health care providers. The current review aims to provide a simplified and updated knowledge regarding non-invasive prenatal testing (NIPT), its major advantages and disadvantages and summarizes the role of ultrasound in patients with negative NIPT.

AbstractThere is a problem with the current nomenclature of prenatal evaluation. The current nomenclature of “prenatal testing” and “prenatal screening” – along with their subsets of “ultrasound testing,” “ultrasound screening,” “non-invasive prenatal testing,” “non-invasive prenatal screening,” and “prenatal diagnosis” – has become so imprecise that clinical misinterpretation and distortion of the informed consent process are increasingly difficult to avoid. To remedy this problem, we propose a new, precise nomenclature: “fetal analysis with invasive method” (FA-I) and “fetal analysis with non-invasive method,” (FANI) using various techniques. This new nomenclature is designed to be precise and therefore facilitate effective communication among physicians and with pregnant women. For ease of use the new nomenclature can be formulated as an abbreviation: FA-I and FA-NI.
