Patient-Reported Outcomes (PROs) and Patient-Reported Outcome Measures (PROMs) are essential in clinical research and healthcare service evaluation. PROs are direct patient reports about their health, quality of life, or functional status, while PROMs are tools used to measure these outcomes. The paper discusses the importance of involving patients in research, including patient-reported experiences (PREMs) and patient and public involvement (PPI) initiatives. PROs and PROMs provide a more comprehensive understanding of treatment effects, including clinical and patient-reported benefits. PROMs are validated tools that ensure accurate and reliable measurement of patient-reported outcomes. The development of PROMs has been driven by the need to improve healthcare quality and safety, with increasing international attention on their use as quality indicators. Challenges in PROM development include ensuring validity, reliability, and generalizability, as well as adapting PROMs for different populations. The use of digital platforms has improved the feasibility and cost-effectiveness of collecting PROM and patient experience data. PREMs, such as satisfaction scales, help assess patient experiences with healthcare services. PPI involves patients and the public in the research process, enhancing the relevance and quality of health research. The paper emphasizes the importance of involving patients in healthcare research to ensure that research is patient-centered and of maximum value. The integration of PROs, PROMs, and PPI into healthcare research and practice is crucial for improving patient care and service delivery.Patient-Reported Outcomes (PROs) and Patient-Reported Outcome Measures (PROMs) are essential in clinical research and healthcare service evaluation.
