United States medical school graduate interest in radiology residency programs as depicted by online search tools.

Recent media publications have indicated a tough job market in medical specialty positions for medical school graduates, specifically in the field of radiology. Internet search tools, such as Google Trends, have proved useful in the prediction of certain diseases on the basis of the search volume index for a specific term. The authors hypothesized that online search tools might be useful in the prediction of US medical school graduates' interest in residency positions in radiology. Google Trends indicated an increase over time in searches for "radiology salary" and a decrease over time in searches for "radiology residency." National Resident Matching Program results for diagnostic radiology showed an increase from 2004 to 2009 in the percentage of US graduates entering radiology but a dramatic drop from 2010 to 2013. This occurred even while the total number of US graduates active in the National Resident Matching Program increased. This finding might have been foretold on the basis of online query result trends. Online search data may be a useful insight into the interests of US medical school graduates and may be predictive of unfilled radiology residency positions and eventual increased shortages of community radiologists coming from US medical schools.
