The National Institutes of Health Patient Reported Outcomes Measurement Information System, or PROMIS®, is a collection of free assessment tools measuring patient–reported health status for physical, mental, and social well–being. Tools are standardized – allowing for easy comparability, inclusive – covering all ages, races, and literacy levels, and they have been tested for validity and reliability. Tools cover anything and everything from pain to emotional distress to vaginal dryness to companionship. So the next time you want to measure patient reports for research or simply to improve your facility’s patient care, check the PROMIS® tools before you re-invent the wheel.
