To evaluate patient choices and uptake of non-invasive prenatal testing (NIPT) for aneuploidy screening offered in a contingency model as part of routine care.
We retrospectively reviewed data for all women with a singleton pregnancy attending for routine first trimester screening over an 18-month period. Women with a 'high-chance' of trisomy 21, 18 or 13 (≥1:150) were offered the choice of no further testing, NIPT or invasive testing, in line with the screening pathway recommended by the UK National Screening Committee.
Of 9342 women attending for a first trimester ultrasound scan, 7939 women were included in this study. Of these, 352 had a high-chance screening result for trisomy 21, and 291 (82.7%) opted for NIPT. The proportion of women opting for NIPT decreased as the chance of trisomy 21 increased: uptake was 93.2%, 90.0%, 77.1% and 47.2% for women with a chance of 1:100-150, 1:50-99, 1:10-49 and >1:10, respectively. 516 women (5.5%) accessed primary NIPT screening in the private sector, and 638 women (6.8%) declined any aneuploidy screening or testing.
Implementation of NIPT testing in a contingency model has a high uptake in a non-research National Health Service setting; the rate of uptake is related to the combined test risk result.
评估在应急模式下提供的非侵入性产前检测（NIPT）用于非整倍体筛查的患者选择和接受情况，该检测作为常规护理的一部分。
我们回顾性分析了在 18 个月的时间内，所有接受常规早孕期筛查的单胎妊娠女性的数据。对于三体 21、18 或 13 （≥1:150）的“高风险”女性，根据英国国家筛查委员会推荐的筛查途径，提供不进行进一步检测、NIPT 或侵入性检测的选择。
在 9342 名接受早孕期超声扫描的女性中，有 7939 名女性纳入本研究。其中，352 名女性的三体 21 筛查结果为高风险，291 名（82.7%）选择了 NIPT。选择 NIPT 的女性比例随着三体 21 的可能性增加而降低：风险为 1:100-150、1:50-99、1:10-49 和>1:10 的女性中，NIPT 的接受率分别为 93.2%、90.0%、77.1%和 47.2%。516 名女性（5.5%）在私立部门接受了初级 NIPT 筛查，638 名女性（6.8%）拒绝任何非整倍体筛查或检测。
在非研究性的国民保健制度环境中，以应急模式实施 NIPT 检测具有较高的接受率；接受率与联合检测风险结果有关。
