The algorithms of datamining, a process in which macro data become knowledge for taking decisions, are currently used to analyse health information. From the use of big data, a greater understanding may be gained of everything surrounding human health from the preventive and clinical viewpoint.
Although these might seem highly sophisticated information systems, there is still a long way to go. In this field, research is under way on how useful it is for medicine to use the data published on the social networks through crowdsourcing. In fact the voluntary participation of citizens connecting to a social network to share health questions produces valuable information that can be analysed and become a useful tool in prevention.
There are many opportunities, but also challenges that have to be considered in creating virtual communities and social networks around health. Cloud computing technologies can improve these experiences in eHealth, which have to be projected along three premises:
A base must be created that allows information to be created, stored and exchanged between different agents and data to be analysed. At this stage, the following must be borne in mind:
If the social networks are used as a platform in which user participation is fostered, the four Ps of medicine can be achieved: preventive, personalised, predictive and participative. Many social networks have emerged, such as patientslikeme.com or 23andme.com, which offer an open platform to everyone who wants to share and compare their pathology with that of other people, or who wish to find out and control their own illness.
To achieve participative supply in the social network, it is important to recruit, retain and assess the users, the semantic management of the queries and the quality of the contributions, as well as to continuously improve the user interfaces. When this is done, in addition to detecting preclinical symptoms, datamining algorithms can be applied to the forums of the social network to identify epidemiological patterns, to study the effectiveness and the side effects of a drug not contemplated in the trials, to monitor and participate in experiments in the real world and even to find new data on treatments, symptoms, progression and medical results.
The ineffectiveness of the present processes and the dependency on paper to store data are the principal barriers on access to eHealth data today. The challenge to increase participation in eHealth projects and on specific social networks is to ensure that medical monitoring is carried out with ubiquity, in other words, the step must be taken to treat the patient only at the hospital and to provide them with tools, such as mHealth to allow them to make a follow-up in any place and at any time.
The current lack of resources in health means that more and more health services are required of the cloud. The creation of platforms of social networks on health on the internet may therefore be a solution to this demand, but the challenges have to be faced. On the one hand the technical challenges, such as limited broadband, which can create bottlenecks in data transmission.
On the other hand, the most important technical challenge lies on the ICT departments of health institutions and bodies, which undergo a change of role from provider to consultant. Furthermore, the users must not be lost sight of, as they are more and more demanding with the measures of control and transparency of these eHealth services.
