Works in both Standalone and Tethered mode. In standalone mode patient can refer to historical records already saved on the device. Tethered to the hospital, via the hospital Portal, the device can communicate with the hospital's EHR files. The absence of tethered integration to the hospital's integrated EHR system leads to the detrimental fragmentation of scattered patient data thus impeding optimum care. Patients with chronic illnesses will be able to track their diseases in conjunction with their providers, promoting early interventions when they encounter a deviation. As communication barriers are responsible for many adverse drug events in an ambulatory (outpatient OP) setting, Improved communication features with the hospital portal makes it easy for patients and caregivers to ask questions, schedule appointments, to request refills, referrals, and to report problems.
