Accreditation is a process in which an entity, separate and distinct from the health care organization, usually nongovernmental, assesses the health care organization to determine if it meets a set of requirements (standards) designed to improve the safety and quality of care. Accreditation is usually voluntary. Accreditation standards are usually regarded as optimal and achievable. Accreditation provides a visible commitment by an organization to improve the safety and quality of patient care, to ensure a safe care environment, and to continually work to reduce risks to patients and staff. Accreditation has gained worldwide attention as an effective quality evaluation and management tool.
