World Patient Safety Day was established in 2019 by the Seventy-second World Health Assembly through the adoption of resolution WHA72.6 – “Global action on patient safety”. The Day is firmly grounded in the fundamental principle of medicine – first do no harm. World Patient Safety Day builds on a series of successful annual global ministerial summits on patient safety which began in London and Bonn in 2016 and 2017, respectively. The overall objectives of the Day are to enhance global understanding of patient safety, increase public engagement in health care safety, and promote global action to prevent and reduce avoidable harm in health care. Each year a theme is selected to shed light on a priority area critical to patient safety and ultimately the achievement of universal health coverage.
