Patients Know Best (PKB) is a Cambridge, England-based platform that provides a personal health record built around a single patient record, aggregating data from healthcare providers, devices, and patient contributions. The system presents this data to patients and professionals through dedicated interfaces and configurable permissions, with patients controlling data-sharing. Founded in 2008 as a social enterprise, PKB is among the UK's first B Corporations, certified in 2015. In the UK, PKB serves more than five million registered patients and processes over twenty million test results each month, with GP data integration for all adults in England completed in Spring 2025 and integration with the NHS App. The company has extended its footprint beyond the UK and EU to Africa, and in 2025 it launched a Population Health Management Engine.
