In the sci-fi classic 2001: A Space Odyssey, an omnipresent computer named HAL monitors all activity aboard a spacecraft on a critical mission. The single-mindedness of this artificial intelligence makes HAL helpful and life-saving, but misses the mark on some decisions that require a more human touch. While our year 2017 has not yet brought us interstellar craft equipped with AI, we are living in a time when technology is supporting almost every field, including healthcare. This post will explore how technology is helping us with hand-hygiene compliance, and how, like HAL, there are some clear advantages as well as some disadvantages. (Thankfully, no hand hygiene technology is able to eject non-compliers out the airlock. Yet.)
