COMPLICATIONS
On the one hand, the research objects of this study are mainly selected from the prenatal diagnosis center of a tertiary hospital in Chengdu, Sichuan Province. The results could be affected by the sample size, economic development level, and comprehensive population quality. Therefore, in future research, researchers can expand the sample size and include pregnant women from the different prenatal diagnosis centers of different provinces and cities as the research objects in the study so as to avoid the impact caused by limitations in sample size, region, and population quality. In addition, there are certain obstacles in data collection, ling-term intervention and follow-up visit due to the various of samples who are mostly from multiple cities in Sichuan and a few form other provinces. Therefore, it has caused certain difficulties in carrying out long-term longitudinal research. Accordingly, in the future research, we can consider selecting local pregnant women and applying the AIDET standard communication health education mode under the King Theory of Goal Attainment, which the study process is: launching an appointment for interventional prenatal diagnosis from obstetric clinic/genetic consultation—clinic-prenatal diagnosis center-intervention—prenatal diagnosis surgery—a longitudinal study of follow-up after interventional prenatal diagnosis, in order to carry out a longer-term effect evaluation (pain perception recovery, activity recovery, complications, etc).
