Postgraduate Obstetrics and Gynaecology Training in Australia: A National Survey of Obstetrics and Gynaecology Fellows.
Postgraduate training in obstetrics and gynaecology has changed in response to shifts in clinical practice. We conducted a national online survey of obstetrics and gynaecology fellowship directors to determine the types of training they offered and the structure and content of the training offered. Directors of Australian obstetrics and gynaecology fellowships were invited to complete an online survey. We determined the prevalence of obstetrics and gynaecology fellowships, compared them with the prevalence of obstetrics and gynaecology training offered in the United Kingdom and United States, and reported the content of training offered in Australia. Seventy-five of 97 potential respondents (78%) responded to the survey. Overall, 31 (43%) of the respondents reported having an obstetrics and gynaecology fellowship, 32 (44%) reported having some obstetrics and gynaecology training, and 12 (16%) reported no training in obstetrics and gynaecology. The majority of obstetrics and gynaecology fellowships offered training in both maternal-foetal medicine and gynaecological surgery (23 of 31 [74%]). Obstetrics and gynaecology fellowships in Australia are prevalent and, overall, offer a similar experience to the United Kingdom and United States. The response rate to this study was low and is probably affected by a number of factors, including lower than anticipated participation in clinical practice by fellows in our specialty. Our study suggests that Australian obstetrics and gynaecology fellowships offer training in maternal-foetal medicine and gynaecological surgery, although not in certain surgical subspecialties such as adolescent medicine, urogynaecology, 3125841983
