Prediabetes is defined as a condition that develops when a patient?s blood sugar level falls between the normoglycemic and diabetic range. Prior research suggests that the loss of ten percent of body mass in a pre-diabetic patient may eliminate or prolong the onset of diabetes. However, a recent study conducted shows that physicians do not know how to diagnose prediabetes. This current investigation explores the spread of prediabetes information through the perspective of the diffusion of innovation theory. Methods. A secondary analysis of the physician assessment on diabetes knowledge established the problem. A follow-up survey was distributed to physicians to explore the effectiveness of communication sources. Results. The presence of barriers to information is associated with less time researching a topic. The most frequently used medium is internet, and the more sources that are used when researching the topic is correlated to a higher perception of knowledge on prediabetes. A physician will attend an information session run by a physician that he admires regardless of the topic. Conclusion. A secondary analysis established that physicians are not correctly diagnosing prediabetes. The follow-up survey suggests confirmation of three hypotheses, hypotheses: (1) physicians are less likely to spend time researching a topic when a barrier is present, even if they perceive ease in accessing medical information, (2) physicians who use more information sources perceive that they are more informed, and that the internet is the most effective medium when researching medical information, and (3) physicians are more likely to attend an information session run by a physician they admire, regardless of the topic.
