Short- and long-term effects of an interdisciplinary outpatient pain program (IOPP) in terms of quality of life, coping strategies, experiencing of pain and pain intensity as well as the influence of age, gender, or migration background.
Single, prospective cohort with assessments at baseline, posttreatment, and at 3, 6, 12 months follow-up.
A total of 175 patients with chronic, nonmalignant pain syndromes (32.1% male and 67.9% female; age 43 ± 9.6 years).
Multi-professional, biopsychosocial-oriented pain program for the duration of 8 weeks.
Pain intensity, Pain Disability Index (German Version of Pain Disability Index, PDI-G), cognitive and behavioral coping strategies (Verarbeitung chronischer Schmerzen FESV), Marburger questionnaire about habitual subjective well-being, and processing of chronic pain (Veränderungsfragebogen des Erlebens und Verhaltens, VEV). The migration background was considered to determine whether this variable influences the clinical outcomes.
All the mentioned variables except pain intensity improved significantly after the program (P < 0.05); whereas, after the 1-year follow-up, most of the parameters returned to the baseline values. Solely the subscale "pain-related psychological strain" remained significantly better compared with baseline (P < 0.05). The variable "migration background" influenced the outcomes PDI-G, habitual well-being, and FESV (P < 0.001; variance of 16.7% [95% confidence interval 7.8-25.5]). After 12 months, 49.4% showed an improvement with regard to the VEV outcome measurement, 22.6% showed no changes, and 28% showed worsening of the symptoms. Gender and age did not influence the results at 12 months (P = 0.408; P = 0.964).
This study provides evidence for the short-term effect of the IOPP in chronic pain patients as well as the long-term effect for the variable "pain-related psychological strain".
评估跨学科门诊疼痛项目（IOPP）在生活质量、应对策略、疼痛体验和疼痛强度方面的短期和长期效果，以及年龄、性别和移民背景的影响。
单组前瞻性队列研究，在基线、治疗后以及 3、6、12 个月随访时进行评估。
共 175 例患有慢性非恶性疼痛综合征的患者（32.1%为男性，67.9%为女性；年龄 43 ± 9.6 岁）。
为期 8 周的多专业、生物心理社会导向的疼痛项目。
除疼痛强度外，所有提到的变量在项目后均显著改善（P < 0.05）；然而，在 1 年随访后，大多数参数恢复到基线值。只有“与疼痛相关的心理压力”亚量表与基线相比仍显著更好（P < 0.05）。变量“移民背景”影响 PDI-G、习惯性幸福感和 FESV 的结果（P < 0.001；方差为 16.7%[95%置信区间 7.8-25.5]）。12 个月后，49.4%的患者在 VEV 结果测量方面有改善，22.6%没有变化，28%的症状恶化。性别和年龄在 12 个月时对结果没有影响（P = 0.408；P = 0.964）。
本研究为 IOPP 在慢性疼痛患者中的短期效果以及“与疼痛相关的心理压力”的长期效果提供了证据。
