Long-term biopsychosocial issues and health-related quality of life in young adolescents and adults treated for childhood Complex Regional Pain Syndrome, type 1.

OBJECTIVES: Treatment for childhood Complex Regional Pain Syndrome (CRPS) is associated with long-term recovery. The present study aimed to investigate the long-term biopsychosocial status and quality of life in young adolescents and adults after the treatment of childhood CRPS. METHODS: A 4 year follow-up of individuals with childhood-CRPS, type 1 (n=22; age:12 years (years) [median] at treatment and 17 years at follow-up) was completed. Biopsychosocial status and quality of life were assessed with structured interviews, using the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), the Strengths and Difficulties Questionnaire (SDQ), the Pediatric Pain Coping Inventory (PPCI), and the Pediatric Quality of Life Inventory (PedsQL). Comparisons were made with normative samples of age-matched controls. RESULTS: CRPS at follow-up was still present in seven out of 22, and non-CRPS pain symptoms were found in 12 out of 22 individuals. Signs of mental health pain-related problems, including phobias and obsessive-compulsive disorder, were observed in ten out of 19 individuals. Mental well-being, social functioning, and quality of life (SDQ and PedsQL) were independent of pain status (p>0.05). Adaptive pain coping strategies were utilized regardless of pain status (PPCI). Social functioning (p<0.01) and the quality of life (p=0.01) were attenuated and statistically significantly poorer than healthy age-matched young adults but better than for fibromyalgia subjects. CONCLUSIONS: A subset of individuals treated for childhood-CRPS, type 1 experiences long-term consequences of persistent pain, a decrease in quality of life indicators, and demonstrates significant psychosocial issues. Childhood-CRPS is suggested to be associated with long-term psychosocial consequences and poorer quality of life than found in age-related healthy peers. Subjects treated for childhood CRPS may need a longer clinical follow-up attempting to preclude relapse of CRPS and non-CRPS pain.
