The WHO has established patient safety as a global health priority in response to the large burden of harm that occurs from unsafe healthcare worldwide. Millions of patients are injured or die each year due to errors, and many common medical practices like medication errors, healthcare-associated infections, and unsafe surgery contribute significantly to this burden. In recognition of this issue, the World Health Assembly designated September 17 as World Patient Safety Day to increase awareness and promote global action. The WHO is working to provide leadership, guidelines, and support to help countries strengthen patient safety, including initiatives to reduce healthcare-associated infections, improve surgical safety, and ensure medication is used safely.
