Patient safety is a modern but not new concept in global health care systems where reports and analyzes indicate that medical errors lead to adverse events. While the issue of safety in any health institution is a criterion in itself and a right of the patient, the importance of avoiding adverse patient events was not known until 1990, when astonishing numbers of statistical reports of multiple countries showed that patient morbidity and mortality had occurred Due to medical and nursing errors worldwide, where these statistics made their way to the public through the most famous statistical report prepared by the Institute of Medicine (IOM) and published in 1990, "To err is human, Kohn, Corrigan & Donaldson, 1990,". The main recommendations of the Medical Institute were to emphasize the need to adopt standards of practice and performance focused more on safety (patient safety).
