Population. A group of persons who have identiﬁed similarities, and includes aggregates and communities.
Population Health. Population health is defined as “the health outcomes of a group of individuals, including the distribution of such outcomes within the group.” (Kindig & Stoddart, 2003, p. 380)(ANA, 2021b)(Centers for Disease Control & Prevention [CDC], 2020)
Quadruple Aim. The Institute for Healthcare Improvement (IHI) defines the Triple Aim as improving the health of populations, enhancing the experience of care for individuals, and reducing the per capita cost of health care. Some organizations have now added a fourth aim, such as attaining joy, health equity and readiness. IHI supports an organization’s additional aim if it assists in achieving the Triple Aim (Feely, 2017).
