Objective To determine how often searching with Google (the most popular search engine on the world wide web) leads doctors to the correct diagnosis.
Design Internet based study using Google to search for diagnoses; researchers were blind to the correct diagnoses.
Setting One year's (2005) diagnostic cases published in the case records of the New England Journal of Medicine.
Cases 26 cases from the New England Journal of Medicine; management cases were excluded.
Main outcome measure Percentage of correct diagnoses from Google searches (compared with the diagnoses as published in the New England Journal of Medicine).
Results Google searches revealed the correct diagnosis in 15 (58%, 95% confidence interval 38% to 77%) cases.
Conclusion As internet access becomes more readily available in outpatient clinics and hospital wards, the web is rapidly becoming an important clinical tool for doctors. The use of web based searching may help doctors to diagnose difficult cases.
