title: Patient questionnaires in rheumatoid arthritis: advantages and limitations as a quantitative, standardized scientific medical history.
abstract: In many chronic diseases, objective gold standard measures such as blood pressure, cholesterol, and bone densitometry often provide most of the information used to establish a diagnosis and guide therapy. By contrast, in inflammatory rheumatic diseases, information from a patient history usually is considerably more prominent in clinical management. Patient history data can be recorded as standardized, quantitative scientific data through use of validated self-reported questionnaires. Patient questionnaires address the primary concerns of patients and their families. Questionnaire scores distinguish active from control treatments in clinical trials at similar levels to swollen and tender joint counts or laboratory tests. Patient questionnaire data are correlated significantly with joint counts, radiographic scores, and laboratory tests, but usually are far more significant than these measures in the prognosis of severe outcomes of rheumatoid arthritis (RA), including work disability, costs, and premature death. Limitations of patient questionnaires are based on cultural features involving variation in responses among ethnic groups, and a need for translation, although translated questionnaires can be as valuable as a translator. Patient questionnaires do not replace further medical history, physical examination, laboratory tests, and imaging data, and they require interpretation in a context of these standard sources of information at any clinical encounter. Patient questionnaires are useful to monitor patient status in usual clinical care, with almost no effort on the part of the physician and staff if distributed by the receptionist in the infrastructure of office practice.
