The 2010 IOM report recommended removing barriers to practice for nurse practitioners to improve access to healthcare.
Step-by-step explanation:
The recommendation made in the 2010 IOM report, The Future of Nursing: Leading Change, Advancing Health, was to remove barriers to practice for nurse practitioners.
