Breve intervención interprofesional para el manejo del dolor crónico: un estudio piloto

ABSTRACT

Objective:

To test the effects of a brief interprofessional intervention for chronic pain management.

Methods:

Before and after pilot study. The brief interprofessional intervention had a psychoeducational focus and was based on the Self-Efficacy Theory, using Cognitive-Behavioral Therapy strategies. The intervention aimed to improve the management of chronic pain. It was conducted in group, over six weeks, with a two-hour weekly meeting, including educational strategies on pain management, stretching, and relaxation techniques. Self-efficacy, pain intensity, disability, fatigue, and depressive symptoms were assessed. Data were analyzed using the paired t-test and Pearson’s correlation.

Results:

Adults with moderate to severe pain took part in the study. Post-intervention analysis showed significant improvement in self-efficacy (p = 0.004) and significant reduction in pain intensity (p = 0.024), disability (p = 0.012), fatigue (p = 0.001), and depressive symptoms (p = 0.042).

Conclusion:

The effects of brief interprofessional intervention were positive for chronic pain management. We suggest the conduction of studies with more robust designs and a larger sample to confirm these findings.

INTRODUCTION

Chronic pain has a high prevalence in the general population and damages quality of life, affecting physical, emotional, cognitive, and social aspects, in addition to causing high costs to society(11. Vieira EBM, Garcia JBS, Silva AAM, Araújo RLTM, Jansen RCS. Prevalence, characteristics, and factors associated with chronic pain with and without neuropathic characteristics in São Luís, Brazil. J Pain Symptom Manage. 2012;44(2):239-51. DOI: https://doi.org/10.1016/j.jpainsymman.2011.08.014
https://doi.org/10.1016/j.jpainsymman.20...
,22. Grol-Prokopczyk H. Sociodemographic disparities in chronic pain, based on 12-year longitudinal data. Pain. 2017;158(2):313-22. DOI: http://dx.doi.org/10.1097/j.pain.0000000000000762
http://dx.doi.org/10.1097/j.pain.0000000...
). Considering the multidimensional characteristic of pain, the interprofessional approach is recommended to achieve positive results for patients with chronic pain(33. Gordon DB, Watt-Watson J, Hogans BB. Interprofessional pain education—with, from, and about competent, collaborative practice teams to transform pain care. Pain Rep. 2018;3(3):e663. DOI: http://dx.doi.org/10.1097/PR9.0000000000000663
http://dx.doi.org/10.1097/PR9.0000000000...
).

Regarding treatment options for chronic pain, the multimodal approach, with the association of pharmacological and non-pharmacological therapies, can contribute to the success of the treatment. Studies that tested chronic pain management programs with interprofessional teams used different components: flexibility and stretching exercises, educational strategies, and relaxation techniques, significantly reducing pain intensity, depressive symptoms, stress, and anxiety(44. Salvetti M, Cobelo A, Vernalha P, Vianna C, Canarezi L, Calegare R. Efectos de un programa psicoeducativo en el control del dolor crónico. Rev Lat Am Enfermagem. 2012;20(5):1-8.).

Educational and psychoeducational strategies are also widely used by nurses and other health professionals to assist in the management of chronic pain. Several studies used educational strategies and achieved positive results in reducing the intensity of pain, anxiety, fatigue, and depressive symptoms(44. Salvetti M, Cobelo A, Vernalha P, Vianna C, Canarezi L, Calegare R. Efectos de un programa psicoeducativo en el control del dolor crónico. Rev Lat Am Enfermagem. 2012;20(5):1-8.,55. Broderick JE, Keefe FJ, Bruckenthal P, Junghaenel DU, Schneider S, Schwartz JE, et al. Nurse practitioners can effectively deliver pain coping skills training to osteoarthritis patients with chronic pain: A randomized, controlled trial. Pain. 2014;155(9):1743-54. DOI: http://dx.doi.org/10.1016/j.pain.2014.05.024
http://dx.doi.org/10.1016/j.pain.2014.05...
).

In the context of psychoeducational strategies, self-efficacy belief is an important variable for the management of chronic pain, defined as the personal perception of the ability to perform certain behaviors to achieve desired results(66. Bandura A. Self-efficacy: Toward a unifying theory of behavioral change. Psychol Rev. 1977;84(2):191-215. DOI: https://doi.org/10.1037/0033-295X.84.2.191
https://doi.org/10.1037/0033-295X.84.2.1...
), which can be understood as self-confidence to perform activities and is related to specific situations. People with higher self-efficacy tend to have fewer depressive symptoms, easier adherence to treatment, less physical disability, and better results in the management of chronic pain(77. Salvetti MG, Pimenta CAM, Braga PE, Corrêa CF. Disability related to chronic low back pain: prevalence abd associated factors. Rev Esc Enferm USP. 2012;46(Spe):16-23. DOI: https://doi.org/10.1590/S0080-62342012000700003
https://doi.org/10.1590/S0080-6234201200...
).

Cognitive-Behavioral Therapy (CBT) is considered the first line of psychosocial treatment for individuals with chronic pain, and aims to address the physical, psychological, and social aspects, with effects on pain and associated problems(88. Palermo TM, McCracken LM, Nicholas MK. Psychological Treatment for Chronic Pain: Improving Access. In: Gold MS, Pogatzki-Zahn EM, Wallace MS, editors. Pain 2018: Refresher Courses, 17th World Congress on Pain. Washington: IASP Press; 2018.,99. Beck J. Terapia cognitiva: teoria e prática. São Paulo: Artmed; 2013.). CBT encourages patients to recognize negative emotions and teaches them to identify automatic negative thoughts in the face of stressful situations in their daily lives. During the sessions, the patient learns to question automatic thoughts and seek evidence about their validity. They are then encouraged to think of alternative views on the situation and to reflect on the emotional response that follows. Based on these self-analysis and reflection exercises(99. Beck J. Terapia cognitiva: teoria e prática. São Paulo: Artmed; 2013.), CBT has stood out as an intervention that promotes the reduction of pain and disability related to chronic pain by modifying negative thoughts and providing new skills to deal with it(88. Palermo TM, McCracken LM, Nicholas MK. Psychological Treatment for Chronic Pain: Improving Access. In: Gold MS, Pogatzki-Zahn EM, Wallace MS, editors. Pain 2018: Refresher Courses, 17th World Congress on Pain. Washington: IASP Press; 2018.).

Nursing interventions that used educational strategies and CBT techniques also showed positive results for patients with chronic pain, contributing to improve knowledge, expand integration, encourage self-care, reduce pain intensity and depressive symptoms, in addition to improving the patients’ perception of self-efficacy(44. Salvetti M, Cobelo A, Vernalha P, Vianna C, Canarezi L, Calegare R. Efectos de un programa psicoeducativo en el control del dolor crónico. Rev Lat Am Enfermagem. 2012;20(5):1-8.,1010. Nash VR, Ponto J, Townsend C, Nelson P, Bretz MN. Cognitive behavioral therapy, self-efficacy, and depression in persons with chronic pain. Pain Manag Nurs. 2013;14(4):236-43. DOI: https://doi.org/10.1016/j.pmn.2012.02.006
https://doi.org/10.1016/j.pmn.2012.02.00...
,1111. Kawi J. Chronic low back pain patients’ perceptions on self-management, self-management support, and functional ability. Pain Manag Nurs. 2014;15(1):258-64. DOI: https://doi.org/10.1016/j.pmn.2012.09.003
https://doi.org/10.1016/j.pmn.2012.09.00...
). Despite the promising results, the content of these interventions, the active elements, the number and duration of sessions to obtain the desired effect are not clear.

Thus, this study aimed to test the effects of a brief interprofessional intervention on self-efficacy belief, pain intensity, disability, fatigue, and depressive symptoms in people with chronic pain, in addition to verifying the possible correlation between disability and self-efficacy belief, pain intensity, fatigue, and depressive symptoms.

METHODS

Design of Study

This is a before and after pilot study.

Population

The study population consisted of people with chronic pain of varying etiologies.

Local

This study was carried out at the School of Nursing of University of São Paulo, with patients treated at the Pain Control Outpatient Clinic of the Anesthesia Division of the Central Institute of the Hospital das Clínicas, School of Medicine, University of São Paulo (ICHC-FMUSP).

Selection Criteria

Inclusion criteria were: age between 18 and 65 years old; moderate to severe pain complaint (pain intensity > 4) for more than six months, according to the Verbal Numerical Scale (VNS)(1212. Hawker GA, Mian S, Kendzerska T, French M. Measures of adult pain. Arthritis Care Res (Hoboken). 2011;63(11):240-52. DOI: http://dx.doi.org/10.1002/acr.20543
http://dx.doi.org/10.1002/acr.20543...
); and living in the Metropolitan Region of São Paulo. Exclusion criteria were: pain of oncological origin; communication and comprehension difficulties; motor deficits; and diagnosis of dementia.

Sample Definition

Non-probabilistic sample composed of 25 people with chronic pain.

Data Collection

Eligibility analysis was performed on medical records of patients who were waiting in the waiting room for medical consultations at the Pain Control Outpatient Clinic of the Anesthesia Division (ICHC-FMUSP). Those who met the inclusion criteria were invited to a nursing interview before the medical appointment. In the interview, the objectives of the brief interprofessional intervention called “Chronic Pain Control Program” were clarified and the patients were invited to take part in the study. With the patients’ expression of interest, they were asked to sign the Informed Consent Form and the initial assessment was carried out.

Intervention

The intervention was operationalized from three theoretical frameworks: Self-Efficacy Theory(66. Bandura A. Self-efficacy: Toward a unifying theory of behavioral change. Psychol Rev. 1977;84(2):191-215. DOI: https://doi.org/10.1037/0033-295X.84.2.191
https://doi.org/10.1037/0033-295X.84.2.1...
), Cognitive-Behavioral Theory(99. Beck J. Terapia cognitiva: teoria e prática. São Paulo: Artmed; 2013.), and Nursing Interventions Classification (NIC)(1313. Bulechek GM, Butcher HK, Mccloskey Dochterman J. Classificação das intervenções de enfermagem (NIC). Rio de Janeiro: Elsevier; 2010.), applied by two nurses, a psychologist, and a physical therapist, over six weeks, with a two-hour weekly meeting, totaling 12 hours. In each session, patients participated in educational and collaborative strategies as recommended by NIC(1313. Bulechek GM, Butcher HK, Mccloskey Dochterman J. Classificação das intervenções de enfermagem (NIC). Rio de Janeiro: Elsevier; 2010.) (one hour in duration), followed by 45 minutes of supervised stretching and 15 minutes of relaxation (Chart 1).

The Self-Efficacy Theory was the main framework for the operationalization of the intervention elements(66. Bandura A. Self-efficacy: Toward a unifying theory of behavioral change. Psychol Rev. 1977;84(2):191-215. DOI: https://doi.org/10.1037/0033-295X.84.2.191
https://doi.org/10.1037/0033-295X.84.2.1...
). Figure 1 shows how each source of information on self-efficacy belief was implemented in the intervention.

Figure 1.
Sources of information on self-efficacy belief operationalized in intervention elements.

In the first meeting, the researchers introduced themselves and the participants and presented the goals. Participants received a kit with an educational booklet and folder on chronic pain management, a notebook, and a pen for notes.

Pain education strategies included background information about the physiology of pain, manifestations of chronic pain, importance of exercise in managing chronic pain, influence of emotions and stress on the painful experience, importance of restful sleep, and maintenance of a healthy rhythm in everyday activities.

During the sessions, the participants performed stretching exercises under the guidance of the physical therapist, breathing and relaxation techniques under the guidance of the nurses, and were instructed to practice these activities at home throughout the week. All these elements have the potential to strengthen the perception of self-efficacy.

On the other hand, cognitive-behavioral strategies included identification of negative thoughts and emotions related to everyday situations and their relationship with pain. Relaxation techniques are also considered behavioral strategies for pain management. Chart 1 shows the distribution of intervention activities over the weeks.

Outcome

To assess the effects of the intervention on self-efficacy belief, pain intensity, disability, fatigue, and depressive symptoms, research instruments were applied on the first day, before starting the intervention, and on the sixth day after the intervention was concluded. Data collection took place from May to October 2019.

Data Collection Instruments

Sociodemographic and clinical data were collected using a questionnaire developed by the authors, containing information on sex, age, schooling, professional status, medical diagnosis, comorbidities, pain intensity, and treatments performed.

Self-efficacy belief was assessed by the Pain Self-Efficacy Questionnaire (PSEQ), validated in Brazil, consisting of 10 items ranging from 0 (no confidence) to 6 (completely confident), indicating the degree of confidence that the individual has to perform activities despite the pain. The higher the score, the higher the self-efficacy(1414. Sardá Júnior J, Nicholas MK, Pimenta CAM, Asghari A. Crenças de autoeficácia relacionadas à dor em uma amostra brasileira de pacientes com dor crônica: uma análise psicométrica. Stress Health. 2007;23(3):185-90. DOI: https://doi.org/10.1002/smi.1135
https://doi.org/10.1002/smi.1135...
).

Pain intensity was assessed using the Verbal Numerical Scale (VNS) of pain, which includes the following question: “please tell me what was the average pain intensity in the last week, considering 0 as no pain and 10 as the worst pain you can imagine”. Pain intensity was categorized as mild (1–3), moderate (4–6), and severe (7–10), and this scale is considered to be of simple and quick application, being widely used in research on pain(1212. Hawker GA, Mian S, Kendzerska T, French M. Measures of adult pain. Arthritis Care Res (Hoboken). 2011;63(11):240-52. DOI: http://dx.doi.org/10.1002/acr.20543
http://dx.doi.org/10.1002/acr.20543...
).

Disability was assessed using the Pain Disability Questionnaire (PDQ), which measures its relationship with pain and has 15 items divided into two domains: physical/functional aspects (9 items) and psychosocial aspects (6 items). The maximum score for physical/functional aspects is 90 points and for psychosocial aspects, 60 points, totaling 150 points for both domains. Disability scores are classified as mild/moderate (0–70), severe (71–100), and extreme (101–150). The questionnaire is considered to be quick to apply and easy to understand, with good psychometric properties(1515. Giordano PCM, Alexandre NMC, Rodrigues RCM, Coluci MZO. The pain disability questionnaire: a reliability and validity study. Rev Lat Am Enfermagem. 2012;20(1):76-83. DOI: https://doi.org/10.1590/S0104-11692012000100011
https://doi.org/10.1590/S0104-1169201200...
).

Fatigue was assessed using the Fatigue Pictogram, an illustrated instrument that is easy and quick to apply for measuring the intensity and impact of fatigue on the patient’s life, consisting of two questions with five captioned illustrations(1616. Mota DDCF, Pimenta CAM, Fitch MI. Fatigue Pictogram: an option for assessing fatigue severity and impact. Rev Esc Enferm USP. 2009;43(Spe): 1079-86. DOI: https://doi.org/10.1590/S0080-62342009000500012
https://doi.org/10.1590/S0080-6234200900...
). The instrument does not have cutoff points for diagnosis or classification, but the higher the score, the greater the intensity and impact of fatigue. Its psychometric properties were satisfactory in Brazil(1616. Mota DDCF, Pimenta CAM, Fitch MI. Fatigue Pictogram: an option for assessing fatigue severity and impact. Rev Esc Enferm USP. 2009;43(Spe): 1079-86. DOI: https://doi.org/10.1590/S0080-62342009000500012
https://doi.org/10.1590/S0080-6234200900...
).

Depressive symptoms were assessed by the Beck Depression Inventory, validated for Portuguese language(1717. Gorenstein C, Andrade L. Inventário de depressão de Beck: propriedades psicométricas da versão em português. Rev Psiquiatr Clín. 1998;25(2): 245-50.), which has 21 items with statements graded from 0 to 3, indicating the intensity of the symptom. The total score ranges from 0 to 63, and the higher the score, the higher the intensity of depressive symptoms. For patients without a previous diagnosis of depression, scores between 16 and 20 should be considered for dysphoria and 21 or more for depression. In this study, the categories for verifying the intensity of depression symptoms were mild (0–15), moderate (16–20), and severe (≥ 21)(1717. Gorenstein C, Andrade L. Inventário de depressão de Beck: propriedades psicométricas da versão em português. Rev Psiquiatr Clín. 1998;25(2): 245-50.).

Data Analysis and Treatment

The data obtained were entered into Microsoft Excel® spreadsheets and analyzed using the Statistical Package for the Social Sciences (SPSS), by descriptive and inferential analyses. Continuous variables were expressed as mean and standard deviation, and categorical variables were described in absolute numbers and percentages. The scores of the measuring instruments were compared using the paired repeated measures Student’s t-test before and after the PCDC. The analysis of the correlation between disability and the variables pain, self- efficacy, fatigue, and depressive symptoms was performed using Pearson’s correlation coefficient. Values of p < 0.05 were considered significant.

Ethical Aspects

The research followed all the recommendations of Resolution no. 466/2012 of the National Health Council (CNS) and was approved by the Research Ethics Committee of EEUSP under opinion no. 2.831.470/2018, in addition to the co-participating institution HCFMUSP under opinion no. 3.339.401/2019. All participants, after understanding the objectives of the intervention and expressing interest, signed the Informed Consent.

RESULTS

Among 48 (100%) patients eligible for the study, 25 (52%) agreed to participate and 15 completed the intervention, assessed before and after the study. The analysis of the characteristics of the program participants (n = 25) showed that 88% were women with 55 years as the mean age and 11 years as mean schooling, 52% were single, and 60% were unemployed, on leave, or retired (Table 1).

Table 1.
Characterization of the Chronic Pain Control Program participants. São Paulo, SP, Brazil, 2019.

Study participants had an average of 10 years of pain and the main etiologic diagnoses were: fibromyalgia, bursitis, arthrosis, herniated discs, and arthritis. The most frequent associated diseases were: hypertension, type II diabetes, hypercholesterolemia, and asthma. The most commonly used drugs: analgesics, anticonvulsants, weak opioids, muscle relaxants, and antidepressants. The mean sleep time was 5 hours a day and 80% of the participants were sedentary.

At the end of the program, there was a significant increase in the self-efficacy score (p = 0.004) and a significant reduction in pain intensity (p = 0.024), disability (p = 0.012), fatigue (intensity: p = 0.016 and impact: p = 0.001), and depressive symptoms (p = 0.042), showing positive results of the program in all variables analyzed (Table 2).

Table 2.
Comparison of the means of the outcome variables before and after the program. São Paulo, SP, Brazil, 2019.

Pain intensity went from severe to moderate, disability went from severe to mild/moderate, and fatigue was reduced, both in intensity and impact for carrying out activities. The mean score of depressive symptoms, despite the reduction, remained in the same category, with mild symptoms.

Correlations between the disability score and the ones of the variables analyzed (self-efficacy, pain intensity, fatigue, and depressive symptoms) were also analyzed. A moderate negative correlation was found between disability and self-efficacy and moderate positive correlations were observed between disability, fatigue, and depressive symptoms. No significant correlation between disability and pain intensity was found (Table 3).

DISCUSSION

The effects of brief interprofessional intervention (PCDC) showed promising results, with significant improvement in self-efficacy and reduction in pain intensity, disability, fatigue, and depressive symptoms. The educational strategies were fundamental for the execution of the PCDC and the achievement of the results obtained.

The systematic review with meta-analysis investigated the effects of 14 randomized clinical trials that tested interventions composed of educational strategies and physical therapy for people with chronic pain(1818. Marris D, Theophanous K, Cabezon P, Dunlap Z, Donaldson M. The impact of combining pain education strategies with physical therapy interventions for patients with chronic pain: A systematic review and meta-analysis of randomized controlled trials. Physiother Theory Pract. 2021;37(4):461-72. DOI: https://doi.org/10.1080/09593985.2019.1633714
https://doi.org/10.1080/09593985.2019.16...
). The results showed that 13 of the 14 studies analyzed showed significant effects of these interventions on short- and long-term pain intensity and long-term disability(1818. Marris D, Theophanous K, Cabezon P, Dunlap Z, Donaldson M. The impact of combining pain education strategies with physical therapy interventions for patients with chronic pain: A systematic review and meta-analysis of randomized controlled trials. Physiother Theory Pract. 2021;37(4):461-72. DOI: https://doi.org/10.1080/09593985.2019.1633714
https://doi.org/10.1080/09593985.2019.16...
). Interventions that include educational strategies present more expressive results compared to interventions that only offer physical therapy(1818. Marris D, Theophanous K, Cabezon P, Dunlap Z, Donaldson M. The impact of combining pain education strategies with physical therapy interventions for patients with chronic pain: A systematic review and meta-analysis of randomized controlled trials.

Research has reinforced the importance of pain education for people with chronic pain(1010. Nash VR, Ponto J, Townsend C, Nelson P, Bretz MN. Cognitive behavioral therapy, self-efficacy, and depression in persons with chronic pain. Pain Manag Nurs. 2013;14(4):236-43. DOI: https://doi.org/10.1016/j.pmn.2012.02.006

http://dx.doi.org/10.1371/journal.pone.0...
). Among the studies that tested educational interventions, many highlight the role of CBT as a resource that promotes behavior modification in the face of painful experiences, highlighting positive effects also regarding self-efficacy, disability, fatigue, and depressive symptoms(1010. Nash VR, Ponto J, Townsend C, Nelson P, Bretz MN. Cognitive behavioral therapy, self-efficacy, and depression in persons with chronic pain. Pain Manag Nurs. 2013;14(4):236-43.

http://dx.doi.org/10.1371/journal.pone.0...
).

This study allowed us to reinforce self-efficacy belief(66. Bandura A. Self-efficacy: Toward a unifying theory of behavioral change. Psychol Rev. 1977;84(2):191-215. DOI: https://doi.org/10.1037/0033-295X.84.2.191
https://doi.org/10.1037/0033-295X.84.2.1...
) as a potential variable mediating the positive effects of interventions aimed at chronic pain management.

The systematic review analyzed the impact of self-efficacy belief in people with rheumatoid arthritis and concluded that its increase was associated with a reduction in pain, depressive symptoms, and anxiety(2121. Martinez-Calderon J, Zamora-Campos C, Navarro-Ledesma S, Luque-Suarez A. The role of self-efficacy on the prognosis of chronic musculoskeletal pain: a systematic review. J Pain. 2018;19(1):10-34. DOI: http://dx.doi.org/10.1016/j.jpain.2017.08.008
http://dx.doi.org/10.1016/j.jpain.2017.0...
). This same study highlighted that individuals with high self-efficacy are more positive, accept their health condition better, and are more willing to perform physical exercises(2121. Martinez-Calderon J, Zamora-Campos C, Navarro-Ledesma S, Luque-Suarez A. The role of self-efficacy on the prognosis of chronic musculoskeletal pain: a systematic review. J Pain. 2018;19(1):10-34. DOI: http://dx.doi.org/10.1016/j.jpain.2017.08.008
http://dx.doi.org/10.1016/j.jpain.2017.0...
).

In this study, the pillars of the self-efficacy belief were worked on throughout the intervention, by the appreciation of personal achievements, observation of colleagues in the program, verbal persuasion by researchers (positive reinforcement), and relaxation techniques. The welcoming environment promoted during the meetings may also have contributed to increase the self-efficacy scores after the program, favoring the achievement of the proposed objectives.

Research points to self-efficacy belief as a key element to be worked on in people with chronic pain, since its decrease is associated with greater pain intensity, depressive symptoms, fatigue, and disability, making adherence to the proposed treatments difficult(77. Salvetti MG, Pimenta CAM, Braga PE, Corrêa CF. Disability related to chronic low back pain: prevalence abd associated factors. Rev Esc Enferm USP. 2012;46(Spe):16-23. DOI: https://doi.org/10.1590/S0080-62342012000700003

,2222. Thompson DP, Antcliff D, Woby SR. Cognitive factors are associated with disability and pain, but not fatigue among physiotherapy attendees with persistent pain and fatigue. Physiotherapy. 2020;106:94-100. DOI: https://doi.org/10.1016/j.physio.2019.01.006
https://doi.org/10.1016/j.physio.2019.01...
).

Another characteristic that may explain the success of the intervention is the group context, which favors social support among members, people with similar problems, who may feel welcomed in the group context, inspired to seek to live better, despite the chronic pain(2323. Finlay KA, Peacock S, Elander J. Developing successful social support: An interpretative phenomenological analysis of mechanisms and processes in a chronic pain support group. Psychology & Health. 2018;33(7):846-71. DOI: https://doi.org/10.1080/08870446.2017.1421188
https://doi.org/10.1080/08870446.2017.14...
)and; (ii. Intervention in sessions also reinforces the second pillar of self-efficacy, since it allows for vicarious experiences or observation of experiences, which contribute to the acquisition of new behaviors(66. Bandura A. Self-efficacy: Toward a unifying theory of behavioral change. Psychol Rev. 1977;84(2):191-215. DOI: https://doi.org/10.1037/0033-295X.84.2.191
https://doi.org/10.1037/0033-295X.84.2.1...
).

This study also sought to assess the effects of PCDC on pain intensity, disability, fatigue, and depression symptoms. Several studies confirm the importance of pain education strategies, with emphasis on knowledge about its neurophysiology, for people who suffer from chronic pain(1919. Davin S, Lapin B, Mijatovic D, Fox R, Benzel E, et al. Comparative effectiveness of an interdisciplinary pain program for chronic low back pain, compared to physical therapy alone. Spine (Phila Pa 1976). 2019;44(24):1715-22. DOI: http://dx.doi.org/10.1097/BRS.0000000000003161
http://dx.doi.org/10.1097/BRS.0000000000...
,2424. Bittencourt JV, Corrêa LA, Reis FJJ, Nogueira LAC. Pain neuroscience education for patients with musculoskeletal pain. Brazilian Journal of Pain. 2020;3(1):89. DOI: http://dx.doi.org/10.5935/2595-0118.20200018
http://dx.doi.org/10.5935/2595-0118.2020...
). This approach promotes changes in beliefs and behaviors, resulting in significant improvement in mental health and functionality, with reduced pain intensity(1919. Davin S, Lapin B, Mijatovic D, Fox R, Benzel E, et al. Comparative effectiveness of an interdisciplinary pain program for chronic low back pain, compared to physical therapy alone. Spine (Phila Pa 1976). 2019;44(24):1715-22. DOI: http://dx.doi.org/10.1097/BRS.0000000000003161
http://dx.doi.org/10.1097/BRS.0000000000...
,2424. Bittencourt JV, Corrêa LA, Reis FJJ, Nogueira LAC. Pain neuroscience education for patients with musculoskeletal pain. Brazilian Journal of Pain. 2020;3(1):89. DOI: http://dx.doi.org/10.5935/2595-0118.20200018
http://dx.doi.org/10.5935/2595-0118.2020...
).

The comparison of the average pain intensity before and after the PCDC showed a significant reduction, going from “severe pain” to “moderate pain,” similar to other interventions for chronic pain management performed in person or by telemonitoring(1818. Marris D, Theophanous K, Cabezon P, Dunlap Z, Donaldson M. The impact of combining pain education strategies with physical therapy interventions for patients with chronic pain: A systematic review and meta-analysis of randomized controlled trials. Physiother Theory Pract. 2021;37(4):461-72. DOI: https://doi.org/10.1080/09593985.2019.1633714
https://doi.org/10.1080/09593985.2019.16...
,2525. Ali YCMM, Sanches MB, Lauretti LG, Salvetti M de G. Effects of a nursing intervention in the control of symptoms in patients with fibromyalgia. Case report. Brazilian Journal of Pain. 2018;1(4):365-8. DOI: https://doi.org/10.5935/2595-0118.20180069
https://doi.org/10.5935/2595-0118.201800...
).

Regarding disability, the mean score changed from “severe” (80.3) before the intervention to “mild/moderate” (62.9) after the intervention, showing a significant reduction. These findings confirm the positive effects of PCDC in improving the functionality of people with chronic pain, as observed in other similar interventions(77. Salvetti MG, Pimenta CAM, Braga PE, Corrêa CF. Disability related to chronic low back pain: prevalence abd associated factors. Rev Esc Enferm USP. 2012;46(Spe):16-23. DOI: https://doi.org/10.1590/S0080-62342012000700003
https://doi.org/10.1590/S0080-6234201200...
,2626. Malta DC, Oliveira MM, Andrade SSCA, Caiaffa WT, Souza MFM, Bernal RTI. Factors associated with chronic back pain in adults in Brazil. Rev Saude Publica. 2017;51 Suppl 1:S1-9. DOI: https://doi.org/10.1590/S1518-8787.2017051000052
https://doi.org/10.1590/S1518-8787.20170...
).

Functionality is essential for maintaining quality of life and ability to work. A study comparing people with and without chronic pain showed that individuals with severe pain are less likely to have a job compared to those with mild to moderate pain, highlighting the loss of productivity and worse performance(2727. Kawai K, Kawai A, Wollan P, Yawn B. Adverse impacts of chronic pain on health-related quality of life, work productivity, depression and anxiety in a community-based study. Fam Pract. 2017;34(6):656–61. DOI: https://doi.org/10.1093/fampra/cmx034
https://doi.org/10.1093/fampra/cmx034...
).

A systematic review that analyzed 41 randomized controlled trials compared usual care associated with physical treatments to the intervention with multidisciplinary biopsychosocial rehabilitation for people with chronic low back pain. The authors concluded that patients who received multidisciplinary biopsychosocial treatment had less pain intensity and less disability compared to those who received only usual care and physical treatment(2828. Kamper SJ, Apeldoorn AT, Chiarotto A, Smeets RJEM, Ostelo RWJG, Guzman J, et al. Multidisciplinary biopsychosocial rehabilitation for chronic low back pain: Cochrane systematic review and meta-analysis. BMJ. 2015;350(h444):1-11. DOI: https://doi.org/10.1136/bmj.h444
https://doi.org/10.1136/bmj.h444...
). Therefore, the relevance of interventions with an educational, psychosocial, and interprofessional approach in the management of chronic pain is emphasized.

This study also analyzed the effects of PCDC on fatigue. The results indicated a significant decrease in fatigue intensity and impact. A study that compared people with chronic low back pain undergoing an interdisciplinary program or physical therapy sessions showed that the interdisciplinary program promoted a significant reduction in fatigue, which corroborates the findings of this study in this regard(1919. Davin S, Lapin B, Mijatovic D, Fox R, Benzel E, et al. Comparative effectiveness of an interdisciplinary pain program for chronic low back pain, compared to physical therapy alone. Spine (Phila Pa 1976). 2019;44(24):1715-22. DOI: http://dx.doi.org/10.1097/BRS.0000000000003161
http://dx.doi.org/10.1097/BRS.0000000000...
).

Depressive symptoms are also common in people with chronic pain. Hence the recommendation to use psychoeducational and behavioral approaches in programs for chronic pain, as tested in this study(44. Salvetti M, Cobelo A, Vernalha P, Vianna C, Canarezi L, Calegare R. Efectos de un programa psicoeducativo en el control del dolor crónico. Rev Lat Am Enfermagem. 2012;20(5):1-8.,2727. Kawai K, Kawai A, Wollan P, Yawn B. Adverse impacts of chronic pain on health-related quality of life, work productivity, depression and anxiety in a community-based study. Fam Pract. 2017;34(6):656–61. DOI: https://doi.org/10.1093/fampra/cmx034
https://doi.org/10.1093/fampra/cmx034...
). The analysis of the effects of PCDC showed a significant reduction in depressive symptoms, even in the brief format, lasting six weeks.

Pain-related disability can lead to reduced productivity, absenteeism, absence from work, social isolation, depression, among other losses(1010. Nash VR, Ponto J, Townsend C, Nelson P, Bretz MN. Cognitive behavioral therapy, self-efficacy, and depression in persons with chronic pain. Pain Manag Nurs. 2013;14(4):236-43. DOI: https://doi.org/10.1016/j.pmn.2012.02.006
https://doi.org/10.1016/j.pmn.2012.02.00...
,1919. Davin S, Lapin B, Mijatovic D, Fox R, Benzel E, et al. Comparative effectiveness of an interdisciplinary pain program for chronic low back pain, compared to physical therapy alone. Spine (Phila Pa 1976). 2019;44(24):1715-22. DOI: http://dx.doi.org/10.1097/BRS.0000000000003161
http://dx.doi.org/10.1097/BRS.0000000000...
,2020. Joypaul S, Kelly F, McMillan SS, King MA. Multi-disciplinary interventions for chronic pain involving education: A systematic review. PLoS One. 2019;14(10):e0223306. DOI: http://dx.doi.org/10.1371/journal.pone.0223306
http://dx.doi.org/10.1371/journal.pone.0...
). Considering this negative impact of disability on the lives of people with chronic pain, this study tested the possible correlation between disability and the variables analyzed: self-efficacy, pain intensity, fatigue, and depressive symptoms.

A moderate negative correlation was identified between disability and self-efficacy, showing that the higher the self- efficacy score, the lower the disability score. On the other hand, there was no significant correlation between disability and pain intensity, which confirms findings from other studies, which indicate absence of a linear relationship between these two concepts(2929. Karasawa Y, Yamada K, Iseki M, Yamaguchi M, Murakami Y, Tamagawa T, et al. Association between change in self-efficacy and reduction in disability among patients with chronic pain. PLoS One. 2019;14(4):e0215404. DOI: https://doi.org/10.1371/journal.pone.0215404
https://doi.org/10.1371/journal.pone.021...
,3030. Ferrari S, Chiarotto A, Pellizzer M, Vanti C, Monticone M. Pain Self-Efficacy and Fear of Movement are Similarly Associated with Pain Intensity and Disability in Italian Patients with Chronic Low Back Pain. Pain Pract. 2015;16(8):1040-47. DOI: http://dx.doi.org/10.1111/papr.12397
http://dx.doi.org/10.1111/papr.12397...
).

A research conducted in Japan analyzed disability, self- efficacy, anxiety and depression, and pain intensity in people with chronic pain(2929. Karasawa Y, Yamada K, Iseki M, Yamaguchi M, Murakami Y, Tamagawa T, et al. Association between change in self-efficacy and reduction in disability among patients with chronic pain. PLoS One. 2019;14(4):e0215404. DOI: https://doi.org/10.1371/journal.pone.0215404
https://doi.org/10.1371/journal.pone.021...
). The results showed that changes in anxiety and depression were not associated with disability, while increased self-efficacy was related to decreased disability, but pain was not correlated with disability(2929. Karasawa Y, Yamada K, Iseki M, Yamaguchi M, Murakami Y, Tamagawa T, et al. Association between change in self-efficacy and reduction in disability among patients with chronic pain. PLoS One. 2019;14(4):e0215404. DOI: https://doi.org/10.1371/journal.pone.0215404
https://doi.org/10.1371/journal.pone.021...
). Other authors suggest that the treatment for chronic pain should focus on improving self-efficacy beliefs, which have the potential to contribute to reducing disability(2222. Thompson DP, Antcliff D, Woby SR. Cognitive factors are associated with disability and pain, but not fatigue among physiotherapy attendees with persistent pain and fatigue. Physiotherapy. 2020;106:94-100. DOI: https://doi.org/10.1016/j.physio.2019.01.006
https://doi.org/10.1016/j.physio.2019.01...
,2929. Karasawa Y, Yamada K, Iseki M, Yamaguchi M, Murakami Y, Tamagawa T, et al. Association between change in self-efficacy and reduction in disability among patients with chronic pain. PLoS One. 2019;14(4):e0215404. DOI: https://doi.org/10.1371/journal.pone.0215404
https://doi.org/10.1371/journal.pone.021...
).

The analysis of the relationship between disability and fatigue showed a moderate positive correlation for both the intensity and the impact of fatigue, indicating that the worse the fatigue, the greater the disability. Similar findings were observed in a Portuguese study, which showed a significant relationship between pain and fatigue and also between fatigue and disability in people with chronic pain.

The assessment of the relationship between disability and depressive symptoms in this study showed a moderate positive correlation, indicating that the more depressive symptoms, the greater the degree of disability. One study suggests that working to reduce these symptoms can be considered a significant plan for reduction of disability(77. Salvetti MG, Pimenta CAM, Braga PE, Corrêa CF. Disability related to chronic low back pain: prevalence abd associated factors. Rev Esc Enferm USP. 2012;46(Spe):16-23. DOI: https://doi.org/10.1590/S0080-62342012000700003
https://doi.org/10.1590/S0080-6234201200...
).

This study has limitations that should be pointed out. The main one is the sample size, considered small, even for a pilot study. In the recruitment phase, some participants reported financial difficulties to pay for transportation to participate in the PCDC sessions, in addition to medical consultations and exams on these same dates, factors that could explain the loss of patients over the course of the intervention. Another limitation of the study is the final assessment, with data collection instruments applied by the interventionists themselves, which may have influenced the participants’ responses.

CONCLUSIONS

The brief interprofessional intervention contributed to the improvement of self-efficacy perception and reduction of disability, pain intensity, fatigue, and depressive symptoms in people with chronic pain. This intervention can be applied in primary health care and in specialized outpatient services as a complementary strategy to pharmacological treatment. Considering that this study was a pilot study, it is suggested to test the effectiveness of this intervention proposal for chronic pain with more robust research designs and with larger samples.
