Brief Summary

Fibromyalgia (FM) is a chronic disease characterized by chronic pain, fatigue and loss of function that leads to a significant deterioration in the quality of life. Despite controversies about the most appropriate treatment, studies indicate that a multidisciplinary treatment would be effective. This study aims to analyze the effectiveness and cost-utility of a complex intervention in the quality of life (main variable), the functional impact, the mood and the pain of people with FM treated in the Primary Care Teams (PCTs) of the Catalan Institute of Health (CIH).

Detailed Description

Methods and analysis: Mixed methodology study following the recommendations of the Medical Research Council, with two phases. Phase 1: Randomized pragmatic clinical trial with patients diagnosed with FM and assigned to one of the 11 PCTs of the CIH (Territorial management of "Terras del Ebro"). A total sample of 336 patients is estimated.

The usual clinical practice will be carried out in the control group and the usual practice and the complex treatment, in the intervention group. The complex treatment will be based on health education, aerobic physical exercise and cognitive-behavioral therapy, during 12 weeks in sessions of 2 hours/week. Statistical analysis: Assessment of the standardized mean response and of the size of the standardized effect and multivariate logistic regression analysis will be performed. The economic analysis will be based on useful measures. Phase 2: Qualitative socio-constructivist study to identify the improvement aspects of the intervention according to the results obtained and the opinions and experiences of the participants (patients and professionals). The sampling will be theoretical with 2 discussion groups composed of participants in the intervention and 2 discussion groups of professionals from different PCTs.

Primary Outcome Measures
NameTimeMethod
Change in mood indicator (depression)Change from mood indicator (depression) at 3, 9 and 15 months after the beginning of the study.

To be evaluated with the Hospital Anxiety and Depression Scale (HADS) questionnaire. The scale likert punctuates from 0 to 21 (8 to 10 indicates a doubtful case of anxiety; more than 11 indicates a probable case of anxiety).

Change in tender pointsChange from tender points at 3, 9 and 15 months after the beginning of the study.

Tender points evaluate the presence of pain in 18 areas of the body and will be measured by a scale Likert: 0 (best) to 18 (worst).

Change in functional impact of fibromyalgiaChange from functional impact of fibromyalgia at 3, 9 and 15 months after the beginning of the study.

to be evaluated with the Revised Questionnaire on the Impact of Fibromyalgia (FIQR) It will be measured by a scale Likert: 0 (best) to 100 (worst).

Change in Visual Analog Scale for pain (VAS)Change from VAS at 3, 9 and 15 months after the beginning of the study.

The VAS evaluates the self-perceived intensity of pain by a scale Likert: 0 (absence of pain) to 10 (worst possible pain).

Change in life qualitychange from life quality at 3, 9 and 15 months after the beginning of the study

to be evaluated with the health questionnaire (SF-36v2). It will be measured by a scale Likert: 0 (worst) to 100 (best).

Change in mood indicator (anxiety)Change from mood indicator (anxiety) at 3, 9 and 15 months after the beginning of the study.

To be evaluated with the Hospital Anxiety and Depression Scale (HADS) questionnaire. The scale likert punctuates from 0 to 21 (8 to 10 indicates a doubtful case of anxiety; more than 11 indicates a probable case of anxiety).
