Overview
Health 2.0 refers to a number of related concepts including telemedicine, electronic medical records, mHealth, Connected Health, and the use of the internet by patients themselves such as through messageboards, blogs, and other more advanced systems. A key concept is that patients themselves should have greater insight and control into information generated about them. Traditional models of medicine had patient records (held on paper or a proprietary computer system) that could only be accessed by a physician or other medical professional. Physicians acted as gatekeepers to this information, telling patients test results when and if they deemed necessary. Such a model operates relatively well in situations such as acute care, where information about specific blood results would be of little use to a lay person, or in general practice where results were generally benign. However, in the case of complex chronic diseases, psychiatric disorders, or diseases of unknown etiology patients were at risk of being left without well-coordinated care because data about them was stored in a variety of disparate places and in some cases might contain the opinions of healthcare professionals which were not to be shared with the patient. Increasingly, medical ethics considers such actions to be medical paternalism and are discouraged in modern medicine.
A hypothetical example demonstrates the increased engagement of a patient operating in a Health 2.0 setting: A patient goes to see their primary care physician with a presenting complaint, having first ensured his own medical record was up to date via the internet. The treating physician might make a diagnosis or send for tests, the results of which could be transmitted direct to the patient's electronic medical record. If a second appointment is needed the patient will have had time to research what the results might mean for them, what diagnoses may be likely, and may have communicated with other patients who have had a similar set of results in the past. On a second visit a referral might be made to a specialist. The patient might have the opportunity to search for the views of other patients on the best specialist to go to, and in combination with their primary care physician decides who to see. The specialist gives a diagnosis along with a prognosis and potential options for treatment. The patient has the opportunity to research these treatment options and take a more proactive role in coming to a joint decision with their healthcare provider. They can also choose to submit more data about themselves, such as through a personalized genomics service to identify any risk factors that might improve or worsen their prognosis. As treatment commences, the patient can track their health outcomes through a data-sharing patient community to determine whether the treatment is having an effect for them, and can stay up to date on research opportunities and clinical trials for their condition. They also have the social support of communicating with other patients diagnosed with the same condition throughout the world.
