CPD and SBA Questions for Volume 28 Issue 3

CPD credits can be claimed for the following questions online via the TOG CPD submission system in the RCOG CPD ePortfolio. You must be a registered CPD participant of the RCOG CPD programme (available in the United Kingdom and worldwide) in order to submit your answers. Completion of TOG T/F and SBA questions can be claimed as a Specific Learning Event. Participants can claim two credits per set of questions if at least 70% of questions have been answered correctly. CPD participants are advised to consider whether the articles are still relevant for their CPD, in particular if there are more recent articles on the same topic available and if clinical guidelines have been updated since publication. Please direct all questions or problems to the CPD Office. Tel: +44 (0)207772 6307 or email: cpd@rcog.org.uk.
