Patient safety is a fundamental principle of health care. However, many medical practices and risks associated with health care are emerging as major challenges for patient safety globally and contribute significantly to the burden of harm due to unsafe care. Available evidence suggests hospitalizations in low- and middle-income countries lead annually to 134 million adverse events, contributing to 2.6 million deaths. About 134 million adverse events worldwide give rise to 2.6 million deaths every year. Estimates indicate that in high-income countries, about 1 in 10 patients is harmed while receiving hospital care. This problem affects both high-income countries and low- and middle countries even if priorities and issues may differ. The most important adverse events concern medication procedures, healthcare-associated infections, surgical procedures, injection safety, blood transfusions, venous thromboembolism, sepsis, and diagnostic and radiation errors. Since 1999 when the Institute of Medicine (IOM) published its report “To err is human,” some progress has been made but patient harm is still a daily problem in healthcare. As a matter of fact, new threats are emerging due to population aging, along with new treatments and technologies which must be dealt with in addition to still-unresolved, long-standing problems. In this context, it is very important to adopt an international common strategy that creates networks, shares knowledge, programs, tools, good practices and develop and track indicators focusing on the specific priorities of each country and region.
