Nursing is a service to the individual, family & therefore to society. If this theory has to be individualized to meet the individual needs of the patient, progressive patient care is more appropriate. In 1957, under the sponsorship of the US public health services division of hospital & medical facilities, the extensary memorial hospital began a project known as “PROGRESSIVE PATIENT CARE”, to determine the methodology, for classifying patient based on as evaluation of many factors to make a determination of the best kind of unit to which the patient should be assigned.
