The conservation model is a model of nursing education that was created by Myra Levine in 1989. Levine postulated four main principles that the nurse follow to facilitate healing a patient. They are conserving the patient's: Energy Structural integrity Personal integrity Social integrity The conservation model of nursing is based around the law of conservation of energy, combined with the psycho-social aspects of the individual's needs. Levine believed that these needs are joined within the individual as a "cascade of life events, churning and changing as the environmental challenge is confronted and resolved in each individual’s unique way. The nurse as caregiver becomes part of the patient's environment, bringing to every nursing opportunity his or her own skill, knowledge, and compassion. It is shared enterprise and each participant is rewarded.” It is not clear what extent Levine's ideas have been adopted, but critics suggest that her model focuses too heavily on the patient's current needs and desires, to the detriment of their longer term medical treatment. Background Levine's objective was to find a new and effective method for teaching nursing degree students major concepts and patient care. She wanted her students to provide individualized and responsive patient care, that was less focused on medical procedures, and more on the individual patient's context. This led to the creation of a new nursing theory and approach to patient care. The main focus of Levine's Conservation Model is to promote the physical and emotional well being of a patient, by addressing the four areas of conservation she set out. By aiming to address the conservation of energy, structure, and personal and social integrity, Levine's model helps guide nurses in provision of care that will help support the client's health. Though conservation of physical and emotional well being is the most vital part of attaining a successful outcome for patients, two additional concepts, adaptation and wholeness, are also extremely important in a patient's health; Adaptation- how a patient adapts to the realities of their new health situation- the better a patient can adapt to changes in health, the better they are able to respond to treatment and care. Wholeness - maintains that a nurse must strive to address the client's external and internal environments. This allows the client to be viewed as a whole person, and not just an illness. Conservation - describes the way complex systems are able to continue to function even
