Serious safety events occur as a result of a timely combination of high-risk actions (human error because of the lack of compensatory actions) and high-risk conditions (high likelihood or probability of error). By reducing human error and strengthening process barriers, healthcare organizations have been shown to reduce serious safety events by as much as 80 percent to 90 percent in two years. The variation in results seen among healthcare organizations depends heavily on the current state of the patient safety culture of the organization. The culture of an organization can be described by the mission, vision, values, physician and leadership commitment, accountability, and behaviors of the members of that organization.
The Juran model for patient safety incorporates the Juran Trilogy® (safety planning, safety compliance and control, and breakthrough improvement) to comprehensively create a strong culture of safety, improved human performance and process reliability to reduce medical errors and serious safety events.
