Patient self-report questionnaires such as a multidimensional health assessment questionnaire (MDHAQ) have advanced knowledge concerning prognosis, care, course and outcomes of rheumatoid arthritis (RA). The MDHAQ may overcome some limitations of a "biomedical model," the dominant paradigm of contemporary medical services, including limitations of laboratory tests, radiographs, joint counts, and clinical trials, to predict and depict the long-term course and outcomes of RA. A complementary "biopsychosocial model" captures components of a patient medical history on patient questionnaires as quantitative, standard, "scientific" scores for physical function, pain, fatigue, and other problems, rather than as 'subjective" narrative descriptions. A rationale for a biopsychosocial model in RA includes the importance of a patient history in diagnosis and management compared to biomarkers in many chronic diseases such as hypertension and diabetes. Some important observations which support a biopsychosocial model in RA based on patient questionnaires include that MDHAQ physical function scores are far more significant than radiographs or laboratory tests to predict severe RA outcomes such as work disability and premature death; patient self-report measures are more efficient than tender joint counts and laboratory tests to distinguish active from control treatments in RA clinical trials involving biological agents; and MDHAQ scores are more likely than laboratory tests to be abnormal at presentation and to document incomplete responses to methotrexate at initiation of biological agents. Patient questionnaires can save time for doctors and patients, and improve doctor-patient communication. A standardized database of MDHAQ scores consecutive patients over long periods might be considered by all rheumatologists in routine clinical care.
