Evolko Systems’ artificial intelligence (AI) and machine-learning (ML) based solution spans the complete patient treatment lifecycle Pre-Consultation, Robotic Triage: Prescreens the patient setting baseline medical history and prepares a disease-specific clinical profile for the doctor, thereby increasing doctor capacity. It also generates an unassociated non-communicable disease (NCD) risk assessment to enable their early detection and treatment, thereby preventing longer term complications with associated higher costs. Patients use Robotic Triage via their mobile app while booking a remote consult. In the clinic, Robotic Triage is used by a physician assistant on a mobile tablet. Peri-Consultation, Adaptive RxPad: Lets doctors create while adapting to the doctors’ style. RxPad comes with the Protocol feature enabling the creation of the entire disease-specific treatment with a single click. RxPad saves treatment plans in the built-in EMR and provides doctors instant access to the records when they need it. In villages Robotic Triage is used by telemedicine operators. Post consultation, HealthRADAR: Patients use the Evolko mobile app for remote self-monitoring during follow-up; it intelligently gathers disease-pertinent information from the patient and reports status and the onset of complications asynchronously back to the doctor’s HealthRADAR for timely review, saving patients the time and expense of rushing back for every minor follow-up issue. The mobile app can also provide dynamic diet plans to patients in the cuisine of their choice and helps them track calorie intake.
