Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in childhood, yet unlike adult arthritis, little is known about its economic impact. A new study published in the February 2007 issue of Arthritis Care & Research (http://www.interscience.wiley.com/journal/arthritiscare) examined direct medical costs of children with JIA and found that the economic impact was substantial.
Led by Drs. Ann Clarke, Ciaran Duffy, and Sasha Bernatsky of the McGill University Health Centre in Montreal, Quebec, the study involved 155 children with JIA and 181 controls from two hospitals in Montreal and Vancouver, Canada. Subjects' parents were given a questionnaire about the use of medications and health services during the preceding three months, without specifying any particular disease. Researchers also asked parents about time loss from their work and days missed from school for the children.
The study was the first to quantify an association between JIA disease activity and health care costs and found that the difference in annualized average direct medical costs for the JIA group versus the control group was $1,686. The JIA group also had higher costs related to specialists, health care professionals, and diagnostic tests. The authors note that the "costs were higher for JIA subjects even compared with those of clinic controls, who almost certainly had greater health resource use than the generally healthy pediatric population," adding that the controls had relatively high rates of emergency room visits, assistive devices, surgeries, and inpatient stays, probably due to the fact that some were recruited from orthopedic clinics. When comparing direct medical costs of JIA patients with recent cost estimates for asthma, JIA appeared to be more costly, mostly because of higher medication costs.
The current study does not quantify the long-term medical and socia
