This concluding chapter explores emerging frontiers in health service evaluation, reflecting on critical themes of patient agency, evaluator leadership, and the transformative potential of artificial intelligence (AI). It contextualizes the tension between the scientific and societal purposes of evaluation, highlighting how values and public policy imperatives may shape evaluation practices in the future. By examining the evolving landscape of health services, the chapter draws on emerging paradigms such as co-production and patient-centered approaches. It also outlines how AI is potentially reshaping the evaluator’s role, challenging established methodologies and democratizing access to evaluation tools. These dual developments—redefining health as a value proposition and the rise of AI—are positioned as critical for the future of health service evaluation, offering both challenges and opportunities.
