Clinical Trial Summary

The present feasibility study aims to evaluate the feasibility and adequacy of a multidisciplinary treatment program as a therapeutic option for patients with chronic low back pain referred to the pain unit of the Hospital Clinic of Barcelona. Secondarily, the present study will also evaluate the effect on pain-related outcomes to estimate the number of needed participants for a full trial.

The main questions it aims to answer are:

• Is the proposed multidisciplinary treatment feasible and adequate for chronic low back pain patients?

• Is the proposed multidisciplinary treatment effective in improving pain-related outcomes?

Participants will receive either usual care (pharmacological control) or eight multidisciplinary sessions within two months, composed of therapeutic patient education, mindfulness relaxation, cognitive-behavioural therapy and therapeutic exercise. Besides, participants will be assessed using written questionnaires before and after treatment and two months after treatment.

Researchers will assess the feasibility of the multidisciplinary treatment group and will compare both groups to see if there is any difference in several pain-related outcomes.

Description:

Despite improving pharmacological and surgical medical treatment options, long-lasting low back pain is the most frequent pain disorder and a leading cause of disability. Over the past decades, clinicians have acknowledged that a broader view of disease and disability is needed in chronic conditions treatment. Therefore, biological, psychological and social factors must be addressed to improve such conditions.

The present study aims to evaluate the viability and adequacy of a multidisciplinary treatment program (PAINDOC Program) as a therapeutic option for patients with chronic low back pain referred to the pain unit of the Hospital Clínic of Barcelona. The secondary objectives are to evaluate the effect of the PAINDOC Program on the reduction of pain intensity, the improvement of pain-related disability, the improvement of quality of life, and the reduction of pain catastrophizing.

Intervention

Drug:
• Usual Care
The pharmacological treatment will be individualised according to pain intensity, contraindications and the appearance of adverse effects.

Other:
• PAINDOC Program
The PAINDOC Program consists in: Therapeutic education: The therapeutic education block consists of two parts: an education session called Empowered Relief (ER) and two pain neuroscience education (NDT) sessions. Psychotherapy: The psychotherapy part consists of one group session of one hour, face-to-face and with groups of up to 15 people, given by the psychologist of the pain unit. Mindfulness Meditation: The Mindfulness Meditation consists of one group session of one hour, face-to-face and with groups of up to 15 people. These are given by a nurse from the pain unit. T Therapeutic exercise: The therapeutic exercise module consists of three sessions of one hour each, face-to-face, with small groups of between 6 and 10 patients, and given by the physiotherapist of the pain unit.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Recruitment rate	To obtain this information, the number of participants included in the program for four consecutive months will be calculated. The number of eligible participants, the number of participants included and excluded, and the reasons for exclusion will be detailed.	4 months prior to study start
Primary	Number of participants completing treatment	Acceptable compliance has been defined as at least 80% of participants included in the program completing all program sessions.	2 months
Primary	Follow-up rate	to determine the follow-up rate, the number of participants who complete the evaluations at each evaluation point in the study will be detailed.	4 months
Primary	Acceptance of treatment and detection of barriers	Treatment acceptance will be assessed through a qualitative approach, based on focus groups and content analysis. The study will have a phenomenological approach to understand and know directly the experiences of the participants. The research will be conducted from the interpretive paradigm, as it seeks to understand and interpret the deep meaning of the observed phenomena. In addition, it is based on an inductive methodology that starts from reality to generate theories, so the fieldwork does not start from a hypothesis.	2 months
Secondary	Pain Intensity. Changes from baseline to 2 months after treatment.	Participants will be asked to rate their pain intensity on a horizontal 100-mm Visual Analogue Scale (VAS), ranging from 0 = no pain to 100 = worst imaginable pain. The VAS is a valid and reliable instrument compared with other pain rating scales, and has been well established in clinical practice and research for measuring pain levels in low back pain patients. For patients with subacute or chronic low back pain, the minimum clinically relevant change is considered to be at least 20 mm on a VAS.	Baseline, 2 months, 4 months
Secondary	Pain-related disability. Changes from baseline to 2 months after treatment.	Disability will be assessed using the spanish version of the Oswestry Disability Index (ODI) questionnaire. The ODI is one of the most common specific measurement tools to evaluate the function and disability of lumbar spine pathologies. This questionnaire contains 10 items evaluated from 0 to 5 (higher values indicate greater disability), which correspond to 10 domains. The sum of the 10 scores is expressed as a percentage (ODI score), with ranges from 0% (no disability) to 100% (maximum disability).	Baseline, 2 months, 4 months
Secondary	Health-related quality of life. Changes from baseline to 2 months after treatment.	The spanish version of the Euro Quality of Life 5D-5L (EQ-5D-5L) was used to assess the health related quality of life (HRQL).(10) The EQ-5D-5L consists in two pages: the first one is based on a descriptive system that defines health in terms of five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has five response categories: no problems, slight problems, moderate problems, severe problems, extreme problems.(10) A health state is composed by taking one level for each dimension, and a preference-based scoring function is used to convert the descriptive system to a summary index score (ranging from states worse than dead <0 to full health 1).	Baseline, 2 months, 4 months
Secondary	Pain Catastrophizing. Changes from baseline to 2 months after treatment.	The Spanish version of Pain Catastrophizing Scale (PCS) was used to asses thoughts and feelings related to pain experiences.(9) The PCS is a 13 item self-administered questionnaire composed of 3 subscales: rumination, magnification and helplessness. The PCS uses a 5-point Likert scale with responses ranging from 0 = not at all to 4 = all the time. Overall scores range from 0 to 52 points, the higher the score, the higher is the pain catastrophism level.	Baseline, 2 months, 4 months
