Overview
As part of the NIH Roadmap for Medical Research, the
PROMIS (Patient-Reported Outcomes Measurement Information System) initiative
is developing new ways to measure patient-reported outcomes (PROs), such
as pain, fatigue, physical functioning, emotional distress, and social
role participation that have a major impact on quality-of-life across
a variety of chronic diseases. Clinical measures of health outcomes, such
as x-rays and lab tests, may have minimal relevance to the day-to-day
functioning of patients with chronic diseases. Often, the best way
patients can judge the effectiveness of treatments is by changes in
symptoms. The goal of PROMIS is to improve the reporting and
quantification of changes in PROs.
This initiative applies to a wide range of disorders including
cancer, congestive heart failure, depression, arthritis, and multiple
sclerosis, as well as chronic pain conditions. PROMIS is creating new
paradigms for how clinical research information is collected, used, and
reported. The PROMIS initiative addresses a need in the clinical research
community for a rigorously tested PRO measurement tool that utilizes
recent advances in information technology, psychometrics, and qualitative, cognitive, and
health survey research.
The PROMIS program is developing, testing, and implementing a
reporting system to collect and quantify clinically important
outcomes such as pain, fatigue, physical functioning, emotional
distress, and social role participation. During the first phase
of the initiative (2004 to present), PROMIS formed a network of
researchers that developed questions or "items" to analyze these
five outcomes or "domains." PROMIS is creating a psychometrically-robust computer
adaptive testing (CAT) system, based on item response theory (IRT), to
administer these items. In addition, it is developing a web-based system 
to give clinical researchers access to the item banks and the CAT
system. Whether administered through an iterative CAT system, that
allows research flexibility, or by paper version short forms, PROMIS
has already demonstrated improved efficiency and sensitivity in
comparison with existing PROs. Long-term trials are planned to
address issues of validity and sensitivity to change in clinical
populations. The increased efficiency, flexibility, and sensitivity
of PROMIS holds potential to become a widely-accepted, standardized
PRO measurement tool that will allow greater comparability of studies, with
reduced burden on patients.
As the PROMIS initiative moves to a second phase of Roadmap support, it will continue to advance the field of patient self-reporting in clinical research and practice, by:
- developing new items and domains,
- translating current and future items and domains into other languages such as Spanish and Chinese to facilitate international studies;
- conducting validation studies in large-scale clinical trials in a variety of clinical populations;
- making PROMIS tools accessible to a wider range of clinical researchers and patient-care communities, and optimizing its usability for rapid adoption;
- providing on-going education and outreach to familiarize users with new developments in PROMIS;
- improving PROMIS tools to allow for better outcomes in clinical trials, and, potentially, better individual and clinical decisions;
- engaging stakeholders at all levels, by continuing interactions with other health-related federal agencies, forging new relationships with patients and patient organizations, and establishing public-private partnerships to sustain PROMIS once Roadmap funding ends.
