Synopsis

With growing emphasis on value in health care, there is a need to assess the effects of MRI use on patient health outcomes. The value, or the health outcomes relative to the cost, can be studied using established comparative effectiveness research and outcomes assessment methods. The synthesis of clinical context with test use also allows for analyses of personalized decision making based on test information. The major methods described will include decision analysis, cost effectiveness, and study of intermediate outcomes. These methods can allow for quantification of population level health benefits, comparison with other tests or interventions, and identification of research priorities based on predicted impact.

Target Audience

Clinical radiologists, MRI researchers, trainees

Outcome/Objective

Understand the major methods used to study the value of MRI, including comparative effectiveness and outcomes research.

Purpose

1) To describe the importance of studying the value of MRI as it relates to population-level health outcomes; 2) To provide an overview of major measures and methods for describing the value of MRI.

Description

MRI evolves rapidly and even widespread techniques often have limited assessment of population-level impact. With growing emphasis on health care value, diagnostic imaging utilization and cost are increasingly subject to scrutiny. In order for new MRI techniques to be widely adopted in favor of an existing test, decision makers assess the impact of MRI techniques and existing alternatives on health outcomes. The value, or the health outcomes relative to the cost, can be studied using established comparative effectiveness research and outcomes assessment methods. Furthermore, because patients' clinical circumstances directly affect outcomes, the same methods can evaluate personalized decision making based on test information. Whether to justify increased cost for better treatment outcomes or to quantify the benefit for a unique patient sub-population, these research methods summarize the ability of a diagnostic test to improve patient care. The major methods described will include decision analysis, cost effectiveness, and study of intermediate outcomes. For MRI techniques, studies of value can apply reliability, accuracy, accessibility and other key features of diagnostic tests to projections of downstream events, survival, and quality of life.

Conclusion

To study value, comparative effectiveness and outcomes research methods link MRI use to the quality of clinical decisions and ultimately, patient health outcomes. These methods can provide generalized or specialized outcomes data that are useful to patients, health care providers, policy makers, and researchers.
