This chapter provides a detailed exploration of patient-reported experience measures (PREMs) through the development and validation of short, generic instruments like the howRwe measure. PREMs assess patient perceptions of care providers, complementing outcome-focused PROMs. The chapter describes patient experience in terms of relational (compassion), functional (result satisfaction), and integration (service coordination) properties, emphasizing their roles in assessing quality, accountability, and governance. PREMs are designed to provide rapid, scalable feedback across diverse care settings, enabling valid comparisons and improvements in patient-centred care. Techniques are discussed for sourcing and refining items, ensuring brevity and readability, and applying appropriate scoring mechanisms. Measures like howRwe focus on compassion, communication, timeliness, and reliability, while Result Satisfaction assesses patient happiness with immediate outcomes; Service integration examines the challenges faced by patients with multiple conditions, promoting streamlined, coordinated care. By adopting PREMs, healthcare organizations can optimize experiences, promote integration, and enhance overall quality.
