Like me, you may have noticed that recently the world seems to have become a much smaller place — advances in technology and transport have made it much easier to travel and communicate with colleagues and friends across different continents.

One of the more positive consequences of these technological developments is the increase in opportunities for us to learn from one another. Take wound care, for example — although some types of wounds are more prevalent in certain parts of the world and healthcare systems vary widely (especially with regard to funding), many of the challenges that face healthcare professionals are surprisingly similar. New technology means that methods for dealing with different types of wounds can now be easily disseminated to a worldwide audience.
