The document discusses measuring patient activation using the Patient Activation Measure (PAM) scale in the UK NHS. The PAM scale measures patients' knowledge, skills, and confidence in managing their own health. It has been tested in over 100 studies showing more activated patients experience better health outcomes. The document outlines an evaluation of using PAM in several UK NHS organizations to understand its impacts and how to optimize its use. The evaluation will use qualitative and quantitative methods including interviews and observation over multiple years.
