The Self-Care Deficit Nursing Theory, also known as the Orem Model of Nursing, was developed by Dorothea Orem between 1959 and 2001. It is considered a grand nursing theory, which means the theory covers a broad scope with general concepts that can be applied to all instances of nursing. The central philosophy of the Self-Care Deficit Nursing Theory is that all patients want to care for themselves, and they are able to recover more quickly and holistically by performing their own self-care as much as they’re able. This theory is particularly used in rehabilitation and primary care or other settings in which patients are encouraged to be independent. The self-care requisites identified by Dorothea Orem fall into one of three categories. The first is universal self-care requisites, which are needs that all people have. These include things like air, water, food, activity and rest, and hazard prevention. The second is developmental self-care requisites, which has two sub-categories: maturational, which progress the patient to a higher level of maturation, or situational, which prevent against harmful effects in development. The third category is health deviation requisites, which are needs that come up based on the patient’s condition. If a patient is unable to meet their self-care requisites, a “self-care deficit” occurs. In this case, the patient’s nurse steps in with a support modality which can be total compensation, partial compensation, or education and support. One of the benefits of Dorothea Orem’s Self-Care Deficit Nursing Theory is that it can easily be applied to a variety of nursing situations and patients. The generality of its principles and concepts make it easily adaptable to different settings, and nurses and patients can work together to ensure that the patients receive the best care possible, but are also able to care for themselves. Thanks to Dorothea Orem’s dedication to nursing, as well as her hard work in the field, nurses can use her theory today to care for patients and make their transition from the hospital or full-time care facility to their own home much smoother.
