P2P hálózatok túlterhelt központi szerverek alternatívái lehetnek az egészségügyben.
The possibility of remote monitoring for chronically ill patients will soon become a reality. Now, researchers in South Africa and Australia have devised a decentralized system to avoid medical data overload. They describe the peer-to-peer system in the International Journal of Computer Applications in Technology. People with a range of chronic illnesses, including diabetes, high blood pressure, and heart problems can benefit from advances in monitoring technology. Such devices could send data on a person's symptoms directly to a centralized computer server at their health center. This would allow healthcare workers to take appropriate action, whether in an emergency or simply to boost or reduce medication in response to changes in the patient's symptoms. However, as tele-monitoring is set to become widespread, there will inevitably be an issue of data overload with which a centralized computer will not be able to cope. Computer scientists Hanh Le, Nina Schiff, and Johan du Plessis at the University of Cape Town, working with Doan Hoang at the University of Technology, Sydney, suggest a decentralized approach. Le and colleagues have developed an application to demonstrate proof of principle of how a P2P network could incorporate patient sensors including thermometers, blood-pressure units and electrocardiograms (ECG). It is the latter on which the team has focused to build a P2P heart-monitoring network. The system builds on the team's concept of a physically-aware reference model (a PARM). Their PARM acts as a small-scale, but scalable model of the kind of network overlay that could be built on the internet. Tests have already demonstrated that a continual and unintrusive heart monitoring application could be developed into a working e-health system quickly and simply at low cost using P2P.
IT3 komment: A krónikus betegek folyamatos táv-felügyelete biztosíthatja a megszokott életvitelüket a túlélésükhöz szükséges, magasabb biztonsági szinten. Ugyanakkor, egy ilyen szolgáltatás túlterhelné az egészségügyi központok szervereit. A P2P hálózatok a túlterhelt központi szerverek alternatívái lehetnek az egészségügyben. A módszer lényege, hogy kisebb csoportokban, P2P módszerekkel dolgozzák fel a folyamatos információkat, és csak gond esetén fordulnak a központi szerverhez. A hatékony és olcsó megoldás elektronikus környezetben modellezi a „figyeljünk egymásra” ősi közösségi módszert.
