Management of Chronic Low Back Pain and the Impact on Patients’ Personal and Professional Lives: Results From an International Patient Survey

Quality of Life in Patients with Chronic Low Back Pain and Differences by Sex: A Longitudinal Study

BACKGROUND

The experience of chronic low back pain has a significant impact on the quality of life of affected people, resulting in difficulties in performing basic activities of daily living.

AIM

To study the perceived quality of life of people affected by chronic low back pain and the associated factors by sex.

METHODS

A prospective, longitudinal and observational design was used.

RESULTS

A total of 129 people (58.1% women) with chronic low back pain were studied. The mean pain intensity scores were of moderate severity (6.42 points), with a modest improvement at follow-up (6.17 points). Epidural nerve blocks were the most effective therapeutic intervention in reducing the intensity of pain. Participants described a negative perception of their health with regard to quality of life, with low scores for the two constructs both at baseline (health index, 0.444; perception of health, 38.76 points) and at follow-up (health index, 0.447; perception of health, 40.43 points). Participants had severe functional limitation scores (50.79 points). The results were significantly better among men. There was an inverse relationship between the average pain intensity (β = -0.304; p < 0.001), functional limitation (β = -0.466; p < 0.001) and mental health (β = -0.565; p < 0.001) and quality of life.

CONCLUSIONS

The chronification of low back pain complicates people's biopsychosocial adaptation to life. There is a longitudinal inverse association between pain and functional limitation and health-related quality of life.

Use of General Practitioner Services Among Workers with Work-Related Low Back Pain: A Systematic Review

PURPOSE

Work-related low back pain (WRLBP) is a highly prevalent health problem worldwide leading to work disability and increased healthcare utilisation. General practitioners (GPs) play an important role in the management of WRLBP. Despite this, understanding of GP service use for WRLBP is limited. This systematic review aimed to determine the prevalence, patterns and determinants of GP service use for WRLBP.

METHODS

MEDLINE, Embase via Ovid, Scopus and Web of Science were searched for relevant peer-reviewed articles published in English without any restriction on time of publications. Low back pain (LBP) was considered work-related if the study included workers' compensation claim data analysis, participants with accepted workers' compensation claims or reported a connection with work and LBP. The eligibility criteria for GP service use are met if there is any reported consultation with family practitioner, medical doctor or General Practitioner. Two reviewers screened articles and extracted data independently. Narrative synthesis was conducted.

RESULTS

Seven eligible studies reported prevalence of GP service use among workers with WRLBP ranging from 11% to 99.3%. Only studies from Australia, Canada and the United States met the eligibility criteria. The prevalence of GP service use was higher in Australia (70%) and Canada (99.3%) compared to the United States (25.3% to 39%). The mean (standard deviation) number of GP visits ranged from 2.6 (1.6) to 9.6 (12.4) over a two-year time interval post-WRLBP onset. Determinants of higher GP service use included prior history of low back pain, more severe injury, prior GP visits and younger age.

CONCLUSION

Only seven studies met the eligibility indicating a relative lack of evidence, despite the acknowledged important role that GPs play in the care of workers with low back pain. More research is needed to understand the prevalence, patterns and determinants to support effective service delivery and policy development.

Developing a low back pain guideline implementation programme in collaboration with physiotherapists and chiropractors using the Behaviour Change Wheel: a theory-driven design study

BACKGROUND

Low back pain is still the leading cause of disability and societal burden, with 619 million prevalent cases worldwide in 2020. Most countries produce clinical guidelines to support healthcare professionals in evidence-based care regarding low back pain. However, several studies have identified relatively poor uptake of guidelines. Tailored strategies to facilitate the implementation of guidelines have been argued to increase uptake. This study aimed to develop a contextually tailored implementation programme to enhance evidence-based low back pain care among Danish physiotherapists and chiropractors in primary care.

METHODS

A theory-driven implementation programme development study was conducted using the Behaviour Change Wheel, with high healthcare professional involvement. Data collection included four workshops with seven physiotherapists and six chiropractors from primary care clinics. The development process consisted of [1] establishing a theoretical frame, [2] involving participants, [3] understanding the behaviour, [4] designing the implementation programme, and [5] final implementation programme.

RESULTS

The target behaviours selected (guideline recommendations) for the implementation programme were (i) screening of psychosocial risk factors and (ii) offering patient education. The barriers and facilitators for the selected behaviours were described and linked to intervention functions and behavioural techniques. Finally, the implementation programme comprised five strategies: webinars, e-learning videos, communication exercises, peer learning, and group dialogue meetings. In addition, the programme consisted of implementation support: champions, a physical material folder, a weekly email reminder, a specially designed website and a visit from an implementation consultant. An essential element of the overall programme was that it was designed as a step-by-step implementation process consisting of 16 h of education and training distributed over 16 weeks.

CONCLUSIONS

A programme for implementing low back pain guideline recommendations was developed based on behaviour change theory and four co-design workshops involving healthcare professionals to overcome the contextually identified barriers. A theory-driven approach involving healthcare professionals was useful in identifying relevant target behaviours and tailoring the programme to consider contextual barriers and facilitators for implementation. The effectiveness of the final implementation programme will be evaluated in the project's next phase.

Barriers to the use of clinical practice guidelines: a qualitative study of Danish physiotherapists and chiropractors

PURPOSE

Low back pain (LBP) is the leading cause of disability worldwide. Providing evidence-based practice (EBP) for patients with LBP is more cost-effective compared with non-EBP. To help health care professionals provide EBP, several clinical practice guidelines have been published. However, a relatively poor uptake of the guidelines has been identified across various countries. To enhance future implementation of EBP, the aim of this study was to explore barriers to using LBP guidelines in clinical practice.

MATERIALS AND METHODS

A qualitative constructivist grounded theory design was employed in order to gain an in-depth understanding of the barriers. Semi-structured interviews (+/- observations) of nine physiotherapists and nine chiropractors from primary care in the Central Denmark Region were conducted.

RESULTS

Two key barriers were found to using guidelines in practice: (1) a scepticism due to doubts about validity and applicability of the guidelines, which emerged particularly among physiotherapists; and (2) a deep biomechanical professional identity, due to perceived role, interest, lack of skills, and patient preferences, which emerged particularly among chiropractors.

CONCLUSIONS

For guidelines to be better implemented in practice, these key barriers must be addressed in a tailored strategy. Furthermore, this study showed a difference in barriers between the two professions.

The "future" pain clinician: Competencies needed to provide psychologically informed care

BACKGROUND & OBJECTIVE

Psychologically informed care has been proposed to improve treatment outcomes for chronic pain and aligns with a person-centered approach. Yet implementation lags behind, and studies suggest that a lack of competency leads to poor results. It is unclear what training clinicians require to deliver this care. We examine how we might improve psychologically informed care guided by the needs of the patient and in congruence with the scientific literature with a particular focus on how competencies might be upgraded and implementation enhanced.

METHODS

We selectively review the literature for psychologically informed care for pain. The patient's view on what is needed is contrasted with the competencies necessary to meet these needs and how treatment should be evaluated.

RESULTS

Patient needs and corresponding competencies are delineated. A number of multi-professional skills and competencies are required to provide psychologically informed care. Single-subject methodologies can determine whether the care has the desired effect for the individual patient and facilitate effectiveness. We argue that becoming a competent "pain clinician" requires a new approach to education that transcends current professional boundaries.

CONCLUSIONS

Providing person-centered care guided by the needs of the patient and in line with the scientific literature shows great potential but requires multiple competencies. We propose that training the pain clinician of the future should focus on psychologically informed care and the competencies required to meet the individual's needs. Single-subject methodology allows for continual evaluation of this care.

Determinants of outcomes for patients with chronic low back pain and fear-avoidance beliefs following treatment with specific stabilisation exercises

BACKGROUND

Specific stabilisation exercises (SSE) can combat the debilitating effects of chronic non-specific low back pain (CLBP), improve disability, pain and fear-avoidance beliefs (FAB).

OBJECTIVE

To elicit the determinants of outcome in patients with CLBP with associated FABs after treatment with SSE.

METHOD

Twenty-nine patients (20 females) with CLBP were classified using FAB questionnaire into high or low Work and Physical Activity (PA) subscales. After 4-week treatment, evaluations were done for pain, disability and lumbar spine active range of motion (AROM). Data was analysed exploratory-descriptively with a significance level set at p< 0.05.

RESULTS

Participants were aged 55.24 ± 11.91 years. They scored 19 (65.5%) and 5 (17.2%) respectively on Work and PA subscales. The post-intervention evaluation showed significant differences in all outcomes, but no significant difference between patients with high or low FAB scores for both subscales. PA scores correlated significantly with pain while work scores correlated significantly with disability. Participants' gender predicted disability, pain and AROM with moderate to large effect sizes.

CONCLUSION

SSE can potentially improve disability, pain and range of motion for patients with chronic low back pain regardless of FABQ status. Gender and baseline patient status are potential determinants of outcome of treatment using SSE.

Randomized-controlled trial assessing a digital care program versus conventional physiotherapy for chronic low back pain

Low back pain (LBP) is the world's leading cause of years lived with disability. Digital exercise-based interventions have shown great potential in the management of musculoskeletal conditions, promoting access and easing the economic burden. However, evidence of their effectiveness for chronic LBP (CLBP) management compared to in-person physiotherapy has yet to be unequivocally established. This randomized controlled trial (RCT) aims to compare the clinical outcomes of patients with CLBP following a digital intervention versus evidence-based in-person physiotherapy. Our results demonstrate that patient satisfaction and adherence were high and similar between groups, although a significantly lower dropout rate is observed in the digital group (11/70, 15.7% versus 24/70, 34.3% in the conventional group; P = 0.019). Both groups experience significant improvements in disability (primary outcome), with no differences between groups in change from baseline (median difference: -0.55, 95% CI: -2.42 to 5.81, P = 0.412) or program-end scores (-1.05, 95% CI: -4.14 to 6.37; P = 0.671). Likewise, no significant differences between groups are found for secondary outcomes (namely pain, anxiety, depression, and overall productivity impairment). This RCT demonstrates that a remote digital intervention for CLBP can promote the same levels of recovery as evidence-based in-person physiotherapy, being a potential avenue to ease the burden of CLBP.

Digital Therapeutics (DTx) Expand Multimodal Treatment Options for Chronic Low Back Pain: The Nexus of Precision Medicine, Patient Education, and Public Health

Digital therapeutics (DTx, software as a medical device) provide personalized treatments for chronic diseases and expand precision medicine beyond pharmacogenomics-based pharmacotherapies. In this perspective article, we describe how DTx for chronic low back pain (CLBP) can be integrated with pharmaceutical drugs (e.g., NSAIDs, opioids), physical therapy (PT), cognitive behavioral therapy (CBT), and patient empowerment. An example of an FDA-authorized DTx for CLBP is RelieVRx, a prescription virtual reality (VR) app that reduces pain severity as an adjunct treatment for moderate to severe low back pain. RelieVRx is an immersive VR system that delivers at-home pain management modalities, including relaxation, self-awareness, pain distraction, guided breathing, and patient education. The mechanism of action of DTx is aligned with recommendations from the American College of Physicians to use non-pharmacological modalities as the first-line therapy for CLBP. Herein, we discuss how DTx can provide multimodal therapy options integrating conventional treatments with exposome-responsive, just-in-time adaptive interventions (JITAI). Given the flexibility of software-based therapies to accommodate diverse digital content, we also suggest that music-induced analgesia can increase the clinical effectiveness of digital interventions for chronic pain. DTx offers opportunities to simultaneously address the chronic pain crisis and opioid epidemic while supporting patients and healthcare providers to improve therapy outcomes.

Identification of Responders to Balneotherapy among Adults over 60 Years of Age with Chronic Low Back Pain: A Pilot Study with Trajectory Model Analysis

Balneotherapy may be a relevant treatment for chronic low back pain (LBP) in individuals > 60 years old. This pilot study aimed to determine the effectiveness of balneotherapy for chronic LBP in people > 60 years old and to determine profiles of responders with trajectory model analysis. This was a pilot prospective open cohort study, with repeated measurements using validated questionnaires; participants were their own controls. The primary endpoint was the proportion of participants with a change in pain intensity between the start of treatment and 3 months after treatment assessed with a numeric scale (NS) from 0 to 100 mm, with an effect size (ES) > 0.5. The assessments involved questionnaires that were self-administered on days (D) 1 and 21 and at months 3 and 6. The secondary objective was to determine the profile of responders to balneotherapy. We included 78 patients (69.2% women), mean age 68.3 ± 5.3 years. The mean pain score on the NS was 48.8 ± 19.9 at D1 and 39.1 ± 20.5 at 3 months (p < 0.001). The ES was 0.47 [95% confidence interval [CI] 0.25 to 0.69] for the whole sample; 36% (28/78) had an ES > 0.5; 23% (18/78) had a moderate ES (0 to 0.5); and 41% (32/78) had an ES of zero (14/78) or < 0 (18/78), corresponding to increased pain intensity. The pain trajectory model showed that the change in pain between D1 and D21 for trajectory A (larger reduction in pain intensity) was -50% [95% CI -60 to -27], and for trajectory B (smaller reduction in pain intensity), it was -13% [-33 to 0] (p < 0.001). Between Day 1 and month 3, the change for trajectory A was -33% [-54; 0] and for trajectory B was -13% [-40 to 0] (p = 0.14). Finally, between D1 and month 6, the change for trajectory A was -50% [-60 to 0] and for trajectory B was -6% [-33 to 17] (p = 0.007). The patients in trajectory A reported performing more physical activity than those in trajectory B (p = 0.04). They were also less disabled, with a mean Oswestry Disability Index of 40.4 versus 45.7 for those in trajectory A and B, respectively, (p = 0.03) and had a higher total Arthritis Self-Efficacy Scale score. This real-life study of the effectiveness of balneotherapy on chronic LBP identified distinct pain trajectories and predictive variables for responders. These criteria could be used in decision-making regarding the prescription of balneotherapy, to ensure personalized management of chronic LBP.
