What was a significant finding of the 1994 Harvard Medical Practice Study?

The significant finding of the 1994 Harvard Medical Practice Study was the high incidence of medical errors in hospitals. This study is pivotal in understanding patient safety as it provided robust evidence that medical errors were not only frequent but also led to substantial harm, including adverse events and preventable deaths. By systematically reviewing medical records, the study was able to quantify the extent of errors in hospitals, revealing that approximately one in every 100 hospitalizations involved some form of medical error. This foundational research underscored the need for improvements in healthcare practices and sparked widespread recognition of errors in medicine, ultimately leading to the development of initiatives aimed at enhancing patient safety and reducing error rates.

The other options, while addressing relevant aspects of healthcare quality and safety, do not capture the primary focus and groundbreaking awareness raised by the Harvard Medical Practice Study regarding the prevalence and nature of medical errors in healthcare settings.
