Preventable medical errors kill somewhere between 44,000 and 98,000 people in the United States each year, with some studies placing the number as high as 195,000. One widely discussed approach to addressing the problem of medical errors is improved professional training on safety-science concepts for healthcare professionals. This report evaluates a pilot fellowship program on patient safety conducted in summer 2004 under the auspices of the Jewish Healthcare Foundation and Coro Health Sciences Fellowship. Based on participant surveys and focus groups, along with study data, the report evaluates the curriculum’s design and content, program implementation, and training outcomes, with the intent to provide feedback to inform improvement, redesign, and scale-up of the pilot program.
