Methods: In this descriptive study, questionnaires were mailed to all general practitioners in the Free State private sector. The questionnaire included demographic information about the practitioner, the ultrasound profile of the practice, and the type of machine used. Results: Four hundred and eighty-one questionnaires were sent to general practitioners and 229 (47.6%) were returned. Of the 176 practising respondents, 47 (26.8%) used ultrasound. The majority of ultrasound examinations done per month were obstetrical. Eight practitioners had relevant qualifications for using ultrasound and more than a third (18, 38.3%) had no training in ultrasound use. Less than half (19, 40.4%) of the practitioners that use ultrasound were aware of the South African Association of Ultrasound in Obstetrics and Gynaecology (SASUOG). Conclusions: The response to the questionnaire was low and may have influenced the results. The study indicates that there are general practitioners who perform ultrasound examinations without training. As general practitioners mainly do obstetrical ultrasound, it is recommended that the SASUOG play a bigger role in their training. A diploma course in ultrasound and support from medical aid organisations to only pay full fees to doctors who can prove that they have sufficient ultrasound training and competence will be ideal.
