Importance and Prevalence
Defining Multiple Sclerosis Quality Measures
The American Academy of Neurology Institute (AANI) has developed quality measures since 2008 based on the belief
that specialists should play a major role in selecting and creating measures that will drive performance improvement and
possibly be used in accountability programs in the future. In 2014, the AANI developed a set of multiple sclerosis quality
measures, which was released in 2015 and reaffirmed on July 29, 2017. In 2019, the AANI formed a standing Multiple
Sclerosis (MS) Quality Measurement Set Work Group (work group). The AANI charged this work group with updating
existing and developing new quality measures for patients diagnosed with multiple sclerosis.
Additionally, the Work Group is charged with the surveillance of evolving evidence base to determine if future updates
are needed, as well as development and release of quality improvement tools to assist in the implementation of the
measures in practice. The work group will meet twice yearly to review any new guideline or evidence developments and
testing data. This will allow for more timely updates and maintenance of measures for use in public reporting and
accountability programs.
Prevalence and Impact
The estimated cumulated prevalence of MS among adults in the United States in 2010 was approximately 727,000. In
2017, that number was substantially higher, approximately 914,000.

The prevalence is higher among women with a
female: male ratio of 2.8.

A recent study found that multiple sclerosis health care spending in the United States was $13.9 billion in 2016.

Multiple
sclerosis was one of the health conditions with the highest annual spending growth paid by both public and private
insurance for the year, which may be correlated with the introduction of specialty drug treatment.

Measure Development Process
The AANI identified non-voting facilitators from the Quality Measure Subcommittee and Quality Committee to provide
methodological support and guide the work group to consensus decisions. A call for work group volunteers was made and
a subject matter expert Chair was identified. Work group members were selected based on review of disclosure
statements, subject matter expertise, and measure development experience. All work group members are required to
disclose relationships with industry and other entities to avoid actual, potential, or perceived conflicts of interest. Seated
work group members were instructed to abstain from voting on individual measure concepts if a conflict was present. See
Appendix A.
The AANI measure development process involves a modified Delphi review by the work group to reach consensus on
measures to be developed prior to a 21-day public comment and following the public comment for further refinement.

The measures in this set are being made available without any prior testing. The AAN encourages testing of this
measurement set for feasibility and reliability by organizations or individuals positioned to do so. Select measures will be
beta tested once the set has been released, prior to submission to the Centers for Medicare & Medicaid Services (CMS)
for consideration in Quality Payment Program’s (QPP) Merit-based Incentive Payment System (MIPS) and the National
Quality Forum for possible endorsement. The measurement set will be reviewed for updates at least every six months by
the standing multiple sclerosis measure development work group.
Below is an illustration of the measure development process from proposals, discussion, research, evaluation, to approval.
