As the healthcare decision-making evolves, patient-reported outcomes (PROs) are increasingly getting attention as crucial tools for encapsulating the patient voice in clinical research and routine care. PROs provide instrumental insight into symptoms, treatment impact, and quality of life, directly from the patients’ perspective. Yet, the methods for PRO selection, measurement, and reporting are often inconsistent and ambiguous, restricting their utility for patients and other stakeholders. Bridging this gap is the key for patient-centred healthcare.(1, 2) To address this need, the Patient-Reported Outcomes Tools: Engaging Users & Stakeholders, i.e., PROTEUS Consortium was formed in 2018.(3, 4)
The PROTEUS Consortium is a global partnership of organizations- including clinician groups, research networks, patient advocacy groups, regulatory bodies, and health systems, all united in their commitment to enhancing the use of PROs in both clinical trials and routine clinical practice.(3) The core mission of the Consortium is to enable access for stakeholders across the healthcare ecosystem to high-quality, consistent, relevant, and actionable PRO data to help inform treatment decisions.(3-6)
The unique characteristic of the PROTEUS Consortium is its dual initiative model- PROTEUS-Trials and PROTEUS-Practice.(3, 6) PROTEUS-Trials emphasizes assisting researchers with embedding PROs systematically into clinical trial design, conduct, and reporting; while PROTEUS-Practice facilitates PRO integration into real-world clinical systems.(6) This dual model consists of practical tools and methods for adopting PRO systems within electronic health records (EHRs) and communicating the value of PROs to stakeholders across diverse care settings. These two branches of the Consortium enable robust PRO guidance in both research and applied practice.(3, 5, 6)
Rather than developing separate frameworks, PROTEUS curates and modifies existing best-practice approaches, such as those from the USFDA, International Society for Quality of Life Research (ISOQOL), and the CONSORT-PRO Extension, into practical, user-friendly resources.(3) These consist of checklists, tutorials, guides, and implementation manuals customized for clinical researchers, sponsors, healthcare administrators, and even patient advocates. These materials are evidence-based, openly available, and developed to facilitate adoption without many difficulties, thus ensuring broad applicability across healthcare settings.(3-6)
The Consortium emphasizes stakeholder engagement as it operates with more than 50 partner organizations to co-develop and enhance its resources, collecting real-world feedback through pilot programs, workshops, and collective ventures. This facilitates the robustness, contextual appropriateness, cultural sensitivity, and adaptability of the tool to various healthcare systems. The Consortium’s collective model enables trust while cultivating shared responsibility of the mission to uplift the patient voice in healthcare.(3-6)
In the end, the PROTEUS Consortium is making headway by endorsing agreement on best practices for PRO application, creating a sustainable foundation for knowledge, and facilitating the adoption of patient-centred approaches worldwide. As healthcare systems progress towards more value-based and tailored care models, PROTEUS will act as a crucial facilitator that ensures active patient participation in research in shaping meaningful outcomes.
