Patent US 8,303,500

The invention discloses a wearable/handheld personal communication device with hardware and software sensor modules that sense and analyze all caregiver prescribed/monitored user-lifestyle activities, and deploys such analysis in improving user's overall health in terms of reduced risks for all-cause morbidities/mortalities and eventually a life without drugs. Termed Rx Zero, such method may be prescribed not just for maintaining a healthy lifestyle, but for treatment of chronic diseases with intent to wean the patients to minimal or zero pharmacological intervention, or in combination with medications to improve prognosis of the disease under treatment.The benefits of the Rx Zero method of the present invention extend not only to the individual and the community through high quality healthcare at lower cost, but payers by reducing the loss ratio on account of reduced cost of medical claims, and to the caregivers in terms of an effective tool that disseminates, implements and redefines “Primary Health Care” and “Prevention” at levels beyond the terms' currently understood scope that has transformed healthcare to sickcare.
