Life expectancy forecast (prognosis quoad vitam) is a prediction of how long a person will live with a given disease or health condition. It is based on statistics on the survival rates of people with similar conditions.
Doctors make life expectancy predictions to help patients and their families plan treatment and care. An exact prognosis is not possible, but doctors can give you a general idea of what to expect.
The prognosis depends on many factors:
-
Type and stage of the disease. Some diseases have a better prognosis than others.
-
Age and general health. Young and healthy people tend to live longer.
-
Response to treatment. Treatment can prolong life.
-
Functional status. People who can take care of themselves often live longer.
-
Family support and access to medical care. Good care improves quality of life and survival.
The prognosis is regularly reviewed as the patient's condition changes. Doctors discuss the prognosis with the patient and family and answer their questions. An accurate prognosis is impossible, but realistic expectations help patients and families plan for the future.
