Promis, also known as the Patient-Reported Outcomes Measurement Information System, is a research area that focuses on developing and validating tools for measuring patient-reported outcomes (PROs) in clinical research and practice. The goal of Promis is to provide accurate, efficient, and standardized measures of patients' physical, mental, and social health, which can be used to inform clinical decision-making, assess treatment effectiveness, and improve patient care. Promis instruments cover a wide range of health domains, such as pain, fatigue, physical function, emotional well-being, and social support, and are designed to be easily accessible and applicable across various patient populations and settings. By using Promis tools, researchers and clinicians can obtain meaningful and reliable data on patients' experiences and outcomes, ultimately enhancing the quality of healthcare delivery and patient outcomes.
