The growth of online social networks means that the way in which we communicate with one another – on both a personal and professional level – has become unrecognisable from 10, or even five years ago. From primary school children to grandparents, social media connects the world. Having the power to broadcast your thoughts to a potential audience of millions can be both empowering and daunting. However, the benefits of having an active presence on at least some social channels far outweigh the risks – as long as you’re aware of those risks. This document aims to outline some of these benefits, make you aware of some of these risks and equip you to be active and engaged. We hope this guidance will be useful to any doctors new to social media and those starting out on their medical careers, but also as a reference point for regular users. While this isn’t intended to be definitive guidance, when used in conjunction with the BMA’s social media, ethics and professionalism advice and guidance from organisations such as the GMC (see further reading below), as well as with a heavy dose of common sense, it should cover most eventualities.
