Netting a diagnosis - the phenomenon of searching for health information onlinePremium

Empower yourself with eHealth literacy to navigate online health resources safely and effectively for improved well-being.

In 2024, google processed more than 2 trillion searches, averaging 8.5 billion per day. Of this 5% were health related, that is 425 million per day or 18 million per hour!!

The internet, we must remember, is a double edged weapon. Good and evil are two sides of the same coin. As the largest, most accessible source of health information, available in multiple languages, the internet can empower anyone. By promoting health literacy, we can equip patients with the understanding they need to take control of their well-being, driving prevention and ultimately improving health outcomes.

India has made remarkable progress in promoting digital literacy, for instance, women selling flowers in their seventies confidently uses technology, displaying QR codes for transactions as small as ₹10, and patiently assisting customers who struggle with digital payments. Similarly, there is a pressing need to create awareness and foster eHealth literacy, empowering patients to effectively navigate and utilise digital health resources, and become informed and engaged ePatients.

Support Groups with an online presence (endorsed by appropriate professional society) are reliable. This is a valuable source of patient perspectives, complementing the clinician’s advice. Health information in social media ( Facebook, WhatsApp, You Tube, X, Instagram, Linkedin, Reddit, Pinterest, Tik Tock etc.) if reliable, could increase patient’s knowledge, competence and decision making skills.

Social media platforms offer a unique opportunity for individuals to share their personal health experiences and connect with others who may be going through similar situations. However, it’s essential to exercise caution when consuming health information online. As the Latin phrase “caveat emptor” (let the buyer beware) suggests, it’s crucial to be mindful that anyone can upload and remove information effortlessly.

The quality of health information provided by mobile apps varies significantly. Notably, a study found that 95% of cancer information apps designed for healthcare workers contained scientifically valid information. In contrast, only 32% of cancer information apps intended for the general public provided accurate information. Furthermore, the health app industry has largely evaded regulation and oversight. The accuracy of online symptom trackers in providing correct diagnoses is alarmingly low, with some studies suggesting a success rate as low as 34%. Additionally, these tools often neglect to consider crucial factors such as personal and family medical history.

Anyone with access to the internet and basic computer literacy can upload any information online. Online health information is often not peer reviewed. A forward from a friend or colleague does not mean that the information is accurate, complete or relevant.
