This August 2011 report represents the first-ever comprehensive review by patient groups of health apps as tools for patients to self-manage their own medical conditions. The report analyses the opinions and recommendations of 100 patient groups from around the world (and from different medical specialties). The 100 patient groups describe how health apps address the 6 major health challenges faced by patients who are trying to self-manage their medical conditions. The patient groups highlight a total of 60 health apps that they believe are particularly good at supporting patients’ self-management of medical conditions. The patient groups’ comments allow PatientView to classify the previously-uncharted field of health apps into 34 categories (including categories of apps for 18 different disease areas). The 100 patient groups also point out some of the hurdles that health apps will have to surmount in the future if apps are to remain relevant to patients. The report makes clear that patient groups regard health apps today as a technological revolution, and as a powerful resource to help patients manage their medical condition, treatment, and care. Health apps are seen by patient groups as effective service providers. Apps remind patients to take their treatment properly, ensuring that medicines work to best effect. Apps track symptoms, and provide information about diseases, medicines, and medical devices. And apps are accessible to even poorer and more vulnerable patients—apps are free in many cases (and others are cheaply priced). Thousands of health apps are available today from providers such as Apple and Android. Most health apps are directed at health professionals. But increasing numbers are designed solely for patients. The vast numbers of apps available makes deciding which apps suit which patients a tough task. This new report helps clarify the confusing world of health apps.
