Most patients forget as much as 80% of what their doctor tells them by the time they return home from an appointment. That can make it difficult to follow the doctor’s treatment plan.

To reverse that situation, Mark Friess founded WelVu, a patient engagement system that relies on videotaped visits with doctors to help patients retain and act on their treatment plans. WelVu formats the videotaped encounters for commonly used operating systems, making them available to patients — and other caregivers and family members — on mobile devices, tablets, laptops and desktops.

When patients have information they can retain, share and act on, their adherence to medical treatment plans improves, avoiding unnecessary additional care and costs.
