Dorothea Orem spent her career on a question that sounds trivial and is not: when does a person actually need a nurse? Her answer is the most widely applied theory in practical nursing.
The question
Orem was born on June 15, 1914 in Baltimore, took her nursing diploma at Providence Hospital in Washington, and degrees in nursing education at the Catholic University of America in 1939 and 1945.
She worked in the operating room, on medical and surgical wards, in emergency and in private duty, and then went into administration and curriculum. In 1949 she took a post with the Indiana State Board of Health improving nursing in the state's hospitals.
The job put a question in front of her that nobody had answered properly. She was supposed to say what nurses in these hospitals should be doing — and there was no account of what nursing was for that was precise enough to build a curriculum or a standard on.
Self-care deficit
Orem's answer, published as Nursing: Concepts of Practice in 1971 and refined until 2001, comes in three linked parts.
Self-care. Everyone has a set of requirements they normally meet for themselves — air, water, food, elimination, activity and rest, solitude and social interaction, avoiding hazards, plus additional ones raised by a stage of life or a disease. Orem called the total the therapeutic self-care demand.
Self-care deficit. Nursing is required exactly when a person's ability to meet that demand falls short of it. Not when someone is ill; not when a doctor orders it. When there is a gap. That is the core claim, and it is why the theory is named for the deficit rather than the care.
Nursing systems. The nurse then works in one of three modes — wholly compensatory, doing it for the patient; partly compensatory, sharing it; or supportive-educative, teaching and standing by while the patient does it. The mode is chosen from the size of the deficit and is meant to shrink as the patient recovers.
Why it stuck
Orem's theory is the one most often used to build actual documentation, because it produces assessable questions. What can this patient do? What can they not do? Which of the three modes does that put us in today? Where has the deficit narrowed since yesterday?
It also lines up with Virginia Henderson's definition — helping people do what they would do unaided, and aiming at independence — but turns it into something you can chart against. Rehabilitation, chronic disease management, diabetes and ostomy education, discharge planning and home health are all effectively organized on it.
Orem never earned a doctorate. She received honorary ones from Georgetown, Incarnate Word and Illinois Wesleyan, and the Catholic University of America's alumni achievement award for nursing theory in 1980.
She spent her last twenty-five years in Savannah, Georgia, consulting and writing, and died there on June 22, 2007, at 92.
