Monitoring outcomes of arthritis and longitudinal data collection using patient questionnaires in routine care

Though quantitative data might lead to improved information for clinical decisions, at the present time decisions in routine rheumatology practice generally are based largely on qualitative impressions, rather than on data. Patient questionnaires are readily accessible tools that the rheumatologist can use to go beyond impressions and to institute evidence-based guidelines appropriate to his or her own patient population and practice style. The Health Assessment Questionnaire (HAQ) and its derivatives have been shown to be the best predictors of functional and work disability, costs, joint replacement surgery, and mortality. Such questionnaires are at least as good as joint counts, radiographs, and laboratory tests in predicting these outcomes. Every encounter of a patient with a rheumatologist provides an opportunity to collect data. Based on experience with the Brooklyn Outcomes of Arthritis Registry Database, the author advocates distributing a waiting-room questionnaire to every patient who comes for an office visit. Potential benefits of recording questionnaire-based information include identifying trends or important changes in a patient's pain or physical function, providing a baseline for success with various treatment strategies for conditions of the rheumatologist's own practice, allowing patients an opportunity to express concerns, encouraging patients to disclose information they may feel is too minor to mention, and providing control data for research studies. A short questionnaire designed specifically for clinical, rather than research, use does not create a burden for office staff. Consistent use of patient questionnaires and systematic storage of the information gained can help document, track, and improve patient care in routine rheumatology practice.
