Patient acceptance of transvaginal sonography in the early pregnancy unit setting

To establish the acceptability of transvaginal scanning in patients attending an early pregnancy unit (EPU) due to problems in early pregnancy such as vaginal bleeding.

An unselected group of pregnant women who were less than 8 weeks' gestation were invited to complete a questionnaire before the transvaginal scan regarding their views about the pregnancy and about the scan itself. They were asked to complete a second questionnaire after the scan had been performed. Information was collected about the presenting symptoms and the final diagnosis.

Of a total of 107 patients, the most common reason for attending the EPU was vaginal bleeding (51.4%). The primary concern for the majority of these women was their pregnancy, rather than the scan procedure itself. Their concerns about the scan were not altered by a previous history of miscarriages or by maternal age. After the scan, more than 77% of patients scored < or = 3 out of 10 with regard to discomfort, pain and embarrassment. Only 1.9% experienced marked discomfort, scoring > 8 out of 10. The scores were not altered by the patients' diagnoses. A total of 99% of patients said that they would agree to have a similar procedure in the future.

This questionnaire-based study confirms that patients attending with problems in early pregnancy find transvaginal sonography acceptable.
