Patients Know Best (PKB) provides a comprehensive Personal Health Record (PHR) platform that centralizes patient data from healthcare providers, enabling secure access for both patients and professionals. The platform, launched in 2008, equips users with tools for managing health information, care plans, appointments, and real-time communication with healthcare providers.

Addressing the fragmentation of health information, PKB empowers over 5. 3 million registered patients and a range of healthcare professionals across the UK, further enhanced by its integration with the NHS App to increase accessibility in various environments. Patients Know Best generates revenue through partnerships with healthcare organizations, such as hospitals and health boards, which sponsor access to the PKB platform at no cost to patients.

While specific pricing details are not disclosed, the revenue structure primarily relies on these institutional partnerships to deliver PKB services efficiently to patient populations.
