On March 21, 2011, HHS released its National Strategy for Quality Improvement in Health Care, as mandated by the ACA. The document sets forth three overarching aims for the health care system: better care (high-quality, safer, patient-centered care); healthy people and communities (supporting interventions to address behavioral, social, and environmental determinants of health); and more affordable care. The strategy establishes six priorities to help achieve these aims: reducing harm caused in the delivery of care; engaging each person and family as partners in their care; promoting effective communication and coordination of care; promoting the most effective prevention and treatment practices for the leading causes of mortality, starting with cardiovascular disease; working with communities to promote wide use of best practices; and developing and spreading new health care delivery models.
