Key Factors In The Choice Of Appropriate Outcomes For Clinical Trials

Health research is the foundation of medical knowledge and healthcare system recommendations. Therefore, choosing appropriate outcomes in studies of therapeutic interventions is a fundamental step in producing evidence and, subsequently, for decision-making. In this article, we propose three key factors for the choice of outcomes: the inclusion of patient-reported outcomes, since they focus on the patient's perception of their health status and quality of life; the consideration of clinically relevant outcomes, which are direct measurements of the patient's health status and, therefore, will be decisive in decision-making; and the use of core outcome sets, a tool that standardizes the measurement and interpretation of outcomes, facilitating the production and synthesis of appropriate evidence for the evidence ecosystem. The correct choice of outcomes will help health decision-makers and clinicians deliver appropriate patient-centered care and optimize the use of resources in healthcare and clinical research.
