Objectives: To evaluate short and long-term treatment outcome of children (7-10 years) in comparison to adolescents (11-18 years) with disabling chronic pain following multimodal inpatient pain treatment.
Patients and methods: Thirty-three children and 167 adolescents underwent multimodal inpatient pain treatment. Standardized assessment of pain-related variables, disability, coping, and use of analgesics was performed at admission, 3- and 12-month follow-up.
Results: Children and adolescents displayed similar pain-characteristics at admission. Adolescents demonstrated significantly higher disability and passive pain coping. Children relied more on others when in pain. All core variables (i.e., pain intensity, pain-related disability, school absence and pain-related coping) decreased significantly in both children and adolescents after 3 months. Both groups maintained this decline 12 months later. More than half of the children and adolescents demonstrated a 50%-reduction in pain intensity after 3 months, and almost 60% after 12 months. Use of analgesics was significantly reduced at 3-month follow-up with no additional changes after 12 months. While age did not exert any impact on results, there were significant gender differences in pain intensity and school absence. Girls demonstrated higher pain intensity and higher school absence 1 year following treatment.
Conclusions: Children display similar pain-characteristics to adolescents when entering inpatient treatment. A multimodal inpatient program appears to stop the the long-term vicious cycle of disability and pain for both children and adolescents. The demonstrated gender differences raise issues for further research and the possibility of additional pain management strategies for girls.
