A survey of current use, dilemma and outlook of antenatal ultrasonography in Taiwan

Abstract

Objective: According to World Health Organization's Jungner and Wilson criteria for competent screening programs, routine antenatal ultrasound screening is legit and effective to improve both maternal and perinatal outcomes. Health Promotion Administration, Ministry of Health and Welfare in Taiwan followed expert recommendations and started reimbursing one antenatal ultrasonography around mid-second trimester since 1995. However, medical disputes pertaining to examination results grew, while confusions challenged doctors and patients alike. The aim of this study is to assess current use of antenatal ultrasonography for low-risk pregnancies in Taiwan. Specifically, the indications, test frequencies, test items, methods of payment, obstetricians' opinions on important scan timing and areas to be improved are surveyed and analyzed. An overview of international antenatal ultrasound practice guidelines are examined and compared to enhance the quality of antenatal ultrasound screening in Taiwan. Materials and methods: From December 2015 to December 2016, 925 questionnaires were distributed to all licensed obstetricians registered to Taiwan Association of Obstetrics and Gynecology as well as Taiwan Society of Perinatology. A 10-min self-reporting questionnaire was sent by mail, with stamped return envelopes included. Respondents remained entirely anonymous and disclosed no personal information. Data was collected and analyzed for statistical analysis. Results: Most hospitals are well equipped with ultrasound machines of 3 or more functions. Eighty-eight percent of the obstetricians in Taiwan perform prenatal ultrasonography in every office visit for their patients, mostly free of charge. Scans at gestational age 15–22 weeks, <10 weeks, 11–14 weeks and 28–32 weeks are polled as the most importance in the order of significance. In general, they perceive the one-time antenatal scan offered by the Health Promotion Administration as for general obstetrics scan but not higher-leveled studies. Patient education and doctor-patient communications are opined as the 2 most important aspects to enhance antenatal ultrasound quality. Conclusion: This report is the first of its kind in Taiwan. It could potentially serve as guidance for national health policy innovations in maternal and fetal care, such as increasing frequency of scans, specifications of scan timing, indications and consequences as well as patient education about this screening modality.
