Development of a tool for early referral of children and adolescents with signs and symptoms suggestive of chronic arthropathy to pediatric rheumatology centers.

OBJECTIVE: To develop an easy, time-efficient tool to identify children and adolescents with signs and symptoms suggestive of chronic arthropathies, and to evaluate its interobserver reproducibility and reliability.
METHODS: The instrument used standardized techniques as required for the development of health-related instruments, targeting parents of apparently healthy children and adolescents ages 1-16 years. A multidisciplinary team was involved in the design of the instrument.
RESULTS: Each health professional generated 10-15 questions addressing musculoskeletal complaints that they considered to be the most relevant. A total of 60 questions were listed. During the reduction step, each health professional scored questions from 1 to 4 according to the question's relevance. The tool comprised 12 questions and was administered to the parents of 3 groups: patients with juvenile idiopathic arthritis (JIA; n = 48), children with diffuse musculoskeletal pain (n = 39), and a healthy control group (n = 42). The JIA group achieved the highest scores, followed by the diffuse musculoskeletal pain group and the control group. Nine (18.7%) of 48 patients with JIA and 2 (5.1%) of 39 children with musculoskeletal pain had a score of 5. The interobserver reproducibility was confirmed. All 12 questions were included in the final version of the instrument. We determined that children and adolescents with a score > or =5 should be referred for a rheumatologic evaluation (cluster analysis and logistic regression).
CONCLUSION: Our questionnaire seems to be a useful tool for the early detection of musculoskeletal problems in children that may need a referral for a rheumatologic evaluation.
