This chapter focuses on using data from person-reported outcome measures (PROMs) and experience measures (PREMs) to drive improvements in healthcare quality and performance. Effective decision-making requires accurate analysis and clear presentation of data, yet many healthcare organizations face challenges due to limited analytical expertise and reliance on error-prone tools like spreadsheets. The chapter highlights the need for robust dashboards and statistical tools to convert raw data into actionable insights. Different user roles—managers, clinicians, and analysts—require tailored data formats to track outcomes, detect changes, and make evidence-based decisions. Comparative mean scores, thresholds, time-period analysis, and demographic filters provide context and support strategic decisions. Dashboards offer layered, real-time information to monitor progress and improve outcomes. By addressing the need for professional development in health data analysis, this chapter underscores how PROMs and PREMs can help optimize patient outcomes while reducing costs and enhancing operational efficiency.
