This document introduces patient engagement and participation in healthcare. It describes the spectrum of engagement from passive compliance to active co-design of care and systems. Common manifestations include seeking health information, contributing to care plans, and engaging in advocacy. Technology enables greater engagement through online resources, communication tools, and data generation. Benefits include improved outcomes, safety, and experiences for both patients and clinicians. However, cultural and systemic barriers still limit progress toward ideals of full partnership and co-production.
