Abstract

INTRODUCTION

Chronic pain is highly prevalent in rural Australia with a lack of holistic pain management services.^[1–3] Chronic pain is complex in its etiology and lasts longer than 3–6 months, or beyond the duration required for normal tissue healing after an acutely painful event.^[4] Acute pain is mostly biological in nature, whereas chronic pain results from a combination of biological, psychological, and social factors and often requires a multifactorial approach to evaluation and management.^[4,5] In Australia, one in every five people lives with persistent pain (i.e., 3.24 million Australians in total), and nearly 70% are of working age.^[6] However, referrals to pain specialists occur in <15% of GP consultations, whereas medications are used in nearly 70%.^[6] Access to holistic pain management services is especially poor in regional and rural Australia, with most multidisciplinary-care clinics located in major cities.^1,2 Allied health professionals, who are expected to play a significant role in the non-pharmacological treatment of chronic pain, are underrepresented in rural areas.^[7] Further, those who are able to access pain services often wait months to be seen, with a median wait time of 85 days in provincial (non-capital city) clinics.^[2] Given these challenges, chronic pain patients are often difficult to treat in rural and remote settings.

Mindfulness is a state of awareness characterized by open and non-judgmental recognition of thoughts and sensations and an ability to resist the usual wandering of an individual’s attention.^[8] Usually achieved by meditation, mindfulness is recognized as an effective treatment for chronic pain.^[9] Evidence, thus far, has been characterized by poor quality trials and mixed results, but a growing body of research is further investigating its effectiveness.^[9] Meditation uses a distinct brain pathway – change in the cortical thickness in the brain – to deal with chronic pain. Studies reported that mindfulness meditation promotes cognitive disengagement and also induces a person’s body opioid system to reduce the feeling of pain.^[8,9] Despite inconclusive evidence, the inherent difficulties of mindfulness research, and problems of accessibility in rural settings, mindfulness meditation is an emerging treatment strategy for many chronic pain patients.

This report presents a patient case admitted to a rural hospital in New South Wales, whose quality of life was severely impacted by chronic pain. As an adjunct to medication, mindfulness meditation became an important part of his treatment plan. This report highlights the effectiveness of mindfulness meditation and ends with a discussion of the difficulty accessing these services in rural Australia, and the role technology can play in improving access.

CASE REPORT

DISCUSSION

The case that we have presented was initially an inpatient with chronic pain, who were referred to a rural residential aged care facility because of his ongoing dependency on care for pain. The strength of this case is the illustration of a step-wedge way of managing chronic pain in a monitored setting following the NICE guideline. However, the limitations were: (i) mindfulness meditation and low access to non pharmacological services, like mindfulness meditation in the inpatient setting; (ii) lack of individualized approach in therapy; and (iii) unwillingness to engage in online and app-based guided meditation. An understanding of and engagement with mediation as well as adequate access to such therapy in rural health-care settings would enhance the chance of managing chronic pain in a successful way.

In Western cultures, meditation is typically associated with yogis, hippies, and “self-help gurus,” has struggled to break from its Buddhist roots, and become established in an increasingly secular society. Dan Harris, an American news anchor, wrote a book about meditation after stumbling on the practice whilst working as a “religion correspondent.”^[15] This author asserts that the problem with meditation is that “its most prominent proponents talk as if they have a perpetual pan flute accompaniment,” but, “If you can get past the cultural baggage…you’ll find that meditation is simply an exercise for your brain.”^[15] Commonly, meditation sessions involve focused awareness on an appearance in consciousness, such as the sensation of breathing or the feeling of one’s body while sitting in a chair. Humans are constantly distracted by thought and meditation is the practice of recognizing these thoughts merely as appearances in our consciousness, just like sensations, and then re-orientating oneself to the practice. Each time one notices, they are lost in thought, the act of bringing attention back to the breath or sensations acts to train the mind. Mindfulness has been found to regulate the sensation of acute^[16] and chronic^[8] pain, improve cognition,^[17] and treat anxiety^[18] and depression.^[19]

Mindfulness-based stress reduction (MBSR) is a therapy developed by Jon Kabat-Zinn at the University of Massachusetts.^[20,21] It typically involves a standardized course of 8 weeks of mindfulness meditation sessions, performed once-weekly for 1.5–2.5 h [Figure 1].^[8,22–25] There has been important research in the last decade investigating the role of MBSR in the treatment of chronic pain,^[21,25–27] with inconsistent results. A number of studies show reduced pain intensity in groups treated with MBSR,^[24–26,28] but these improvements may be short lived.^[24] The mechanism by which pain is reduced in these patients has been postulated to be through the effects of medication on psychological factors. Indeed, a number of studies find that the benefits of meditation are most prominent in reducing symptoms of depression and anxiety and improving psychological functioning.^[23,27,29] One important trial, conducted on older patients in in whom pharmacological analgesia is often complicated by adverse effects, found that MBSR led to improvements in chronic pain.^[24] The MBSR approach is fairly common in the literature and has the largest evidence base supporting it; however, there is considerable heterogeneity in the format used depending on billing structure, type of session (guided vs. silent), and other factors. The approach taken by Barry involved ongoing weekly sessions 30 min in length, as facilitated by the meditation guide.

Mindfulness is often associated with cognitive behavioral therapy (CBT), as there are many similarities between the two practices. Both are psychological therapies that encourage the practitioner to examine their thoughts, emotions, sensations, and behaviors. The techniques used in these practices, including deep breathing and self-reflection, are also common to both therapies. CBT has been studied since the 1980s but recent reviews suggest only a small to moderate effect on pain,^[14] with some patients receiving no benefit.^[30,31] Further, a number of studies have compared MBSR and CBT. A systematic review in 2011 found that MBSR was no better than CBT in the treatment of chronic pain, but it may be a good alternative.^[28] Despite the low quality evidence, the authors recommended therapies that combined both mindfulness and behavioral therapy. In a larger, randomized, and interviewer-blind trial, MBSR and CBT were both found to improve chronic low back pain compared to usual care, with no differences identified between MBSR and CBT.^[25] In one RCT of patients with rheumatoid arthritis (RA), CBT conferred the largest improvement in pain, but meditation was more beneficial in RA patients with psychological manifestations of their pain.^[32] The poor quality of many of the studies, however, makes it difficult to conclude the effectiveness of MBSR in treating chronic pain, as noted by a systematic review in 2012.^[22] A more recent RCT of 109 patients found no significant differences in pain measures between MBSR and a wait list control.^[23] Access to psychological therapies such as CBT is often difficult in rural areas. Improvements in technology, such as telehealth conferencing, may improve access to CBT, but the individualized therapy prohibits the scalability offered by online and app-based guided meditation services. Although technology may allow those in rural areas to access CBT services provided in metropolitan areas more easily, the format of one-on-one therapy may limit engagement due to wait times for appointments and out-of-pocket costs.

There are inherent difficulties in performing high quality trials of mindfulness in medical research. Measuring mindfulness is difficult and there is little consensus as to the components of the mindfulness experience.^[27] Much of the research involves self-reporting of results, which exposes trials to significant response bias.^[20] Further, problems emerge when designing control interventions, as many trials involve wait-list controls, where the control group is given no intervention for the study period, then offered the intervention at a later date.^[27] Another factor that compounds inconsistency of intervention is the modification of MBSR,^[27] leading to variability in the intervention given and reduced generalizability. There are also significant difficulties in elucidating the dose-response relationship of mindfulness,^[27] as measuring both the dose of meditation and the response to it is abstract and challenging. Some practitioners achieve benefit almost immediately and some require years of practice.

Further research should prioritize quality and comparison using quantitative measures, where possible. Structured measurements of mindfulness may be used, including scales such as the Mindfulness and Attention Awareness Scale^[33] and the Frieburg Mindfulness Inventory.^[34] A pain assessment in patients before and after the mindfulness session, using the appropriate scale such as Numerical Rating Pain Scale, Wong-Baker Faces Pain Scale, FLACC Scale, CRIES Scale, COMFORT Scale, or McGill Pain Scale would be a better scientific approach to such case study. These measures may allow for quantitative analysis of the effects of meditation and allow for correlation with pain scores. Empirical evidence of the extent of mindfulness may also reveal the most effective meditation techniques, including in specific subpopulations such as those with chronic pain. In addition, the future studies should incorporate active control groups and standardized mindfulness interventions,^[27] to promote comparison between different treatment modalities and to encourage adoption of mindfulness on a larger scale. High-quality RCTs using quantitative measurement of mindfulness and active control groups in chronic pain patients are needed.

There remains the problem of access to meditation services, especially in regional and rural areas. Access to guided meditation can be difficult and expensive. Classes and retreats are often fully booked with existing clients and those taking new clients are expensive. The Meditation Association of Australia suggests fees of up to $400/h for sessions delivered to community groups and $1000/h for businesses.^[35]

CONCLUSION

The search for effective chronic pain treatments is ongoing, but there may be further benefit gained from existing strategies, such as mindfulness meditation and CBT. Our case clarifies the effectiveness of mindfulness, but lack of access to services was evident. It is a reasonable choice for clinicians to advocate for, due to its negligible harms, additional psychological benefits, and increasing accessibility through technology. Access to meditation services in rural and regional Australia may be challenging, but online and app-based programs may provide a new avenue for the treatment of chronic pain.
