Moore, Shirley M., a nursing theorist who, with Cornelia M. Ruland, developed the Peaceful End of Life Theory, which asserts that nurses are integral to the creation of peaceful end-of-life care, which includes freedom from suffering, emotional support, closeness to and participation by significant others, and treatment with empathy and respect. The theory was developed from a standard of care created by expert nurses to manage the care of patients with terminal illness.
