In this new era of the “Connected Patient”, it is easy to understand why a growing number of individuals rely on the internet for medical advice. The option is incredibly convenient and more importantly, free. However, there are a number of compelling reasons why it can be dangerous to use the internet to self-diagnose troubling symptoms.

Harvard Medical School Study

In a 2015 study published in the British Medical Journey, led by Harvard Medical School researchers, most sites reviewed were deemed unreliable as sources of diagnosis and triage i.e. the assignment of degrees of urgency to illnesses to determine the order of treatment. In a nutshell: 23 websites (worldwide) were selected to test 45 patient vignettes (brief descriptions of conditions, half of which were common conditions). The results? The correct diagnosis only surfaced 34% of the time.

Self-Diagnosis: Main Risks

The main risks and issues related to inaccurate and inconsistent information are as follows:

Many people may need urgent medical treatment, but choose to self-diagnose (often incorrectly) and self-medicate – which either does not help or causes more harm.
Many people may not need medical treatment, but seek it anyway out of fear. The results produced by symptom checkers often contribute to hypochondriasis and cyberchondria, i.e. increased anxiety fuelled by digital self-diagnosis.

While symptom checkers can be a good starting point and perhaps facilitate better doctor-patient communication, the results produced should be taken with a grain of salt.

Google and Medical Search Results

Google also plans to show medical details related to illnesses in their search results (first to those conducting mobile searches in the US; later to more countries and in different languages). They have worked with doctors as well as experts from Harvard Medical School and the Mayo Clinic to improve search results. Still, it is important to note that results are intended for information purposes only and medical action should only follow after consulting a doctor.

So What Should You Do?

Despite impressive technology, for example “the medicalized smartphone” or Facetime examinations, nothing (yet) can really replace a well-performed history and physical in a professional office setting, urgent care or emergency department where there is access to diagnostic instruments. Although artificial intelligence may play a more significant role in the future, the art of medicine – the human touch – can not be replaced.
