I love surgery. I always have. Growing up, I always wanted to be a surgeon. I am not sure if it was the movies or the society that influenced me the most but doctors were treated special, and surgeons especially were treated like superheroes. Two years back, we started Scalpel Ltd to improve patient safety in surgery. Since then, our team spent every minute on building tools that reduce the chance of preventable errors in surgery. Along the way, we learnt a lot about why things go wrong in surgery, why the current solutions don’t work, and how can we fix it. This post shares some of those lessons.
