Patient-Reported Outcomes Measurements (PROMs) enable caregivers to compare and improve patient health gains through data-driven communities of practice. This collective dynamic of continuous improvement inspires healthcare professionals, helping them focus on the appropriateness of care and redesigning patient pathways. Implementing PROMs successfully requires standardization, digitalization, inter- operability, patient case-mix and data audits. Beyond routine care, PROMs are opening a new generation of clinical studies and hospital procurement models.
