(2) Any increases or decreases in the quality of care, including:
(a) Improvement or reductions in morbidity;
(b) Improvement or reductions in the management of population health;
(c) Changes to health and patient outcomes, particularly for underserved and uninsured individuals, recipients of medical assistance and other low-income individuals and individuals living in rural areas, as measured by nationally recognized measures of the quality of health care, such as measures used or endorsed by the National Committee for Quality Assurance, the National Quality Forum, the Physician Consortium for Performance Improvement or the Agency for Healthcare Research and Quality.
