Patients Know Best is a company that created the world's first patient-controlled medical records website to give patients access to and control over their own health records. Their system provides a complete electronic health record that can store any medical data while complying with various privacy regulations. Several UK healthcare organizations have already implemented the system, including the NHS, Bupa, and Great Ormond Street Hospital, allowing for online consultations, prescribing, and saving clinician's time by providing detailed explanations directly to patients.
