Clinical errors are the third leading cause of death in the United States. Recent estimates in the United Kingdom also show that, on average, one injury occurs to the patient every 35 seconds. The results of studies show that 10% of hospitalized patients suffer from clinical errors, although in developing countries this risk is 20 times higher than in developed countries.
