Is Google search a useful medical diagnostic tool for third year medical students?

ABSTRACT

Introduction: In recent years, the internet has become an increasingly popular tool for people to obtain information due to the overwhelming availability of material. As internet access becomes more readily available, the newer generation of patients, medical students and doctors are starting to prefer the internet as a source of reference to acquire medical knowledge. The main objectives of this study were to determine the accuracy of using Google search in establishing a clinical diagnosis based on information provided from the New England Journal of Medicine (NEJM) and to determine the concordance rate of Google diagnosis with the actual diagnosis from NEJM. Method: The research design was a cross sectional study of 200 NEJM cases. The research team comprised of four 3rd year medical students and one senior supervisor. Google search engine was used to obtain a diagnosis. The time allocated for a Google search for each case was 20 minutes regardless of the number of websites used. The top two diagnoses were then compared to the actual diagnoses of the NEJM case and the accuracy of Google was then assessed. Results: The study achieved a congruence of 71.5%. This is considered acceptable and satisfactory as the cases presented in NEJM covered a wide variety of problems and encompassed rare diseases. Conclusion: From the final results obtained, it can be concluded that with the aid of Google, medical students in their 3rd year of their Bachelor of Medicine and Bachelor of Surgery programme are able to obtain a reasonable clinical diagnosis.
