Chronic low back pain (CLBP) is associated with a number of costly disability-related outcomes. It has received increasing attention from qualitative researchers studying its consequences for personal, social, and health care experiences. As research questions and methods diversify, there is a growing need to integrate findings emerging from these studies. A meta-ethnography was carried out to synthesise the findings of 38 separate qualitative articles published on the subjective experience of CLBP between 1994 and 2011. Studies were identified following a literature search and quality appraisal. Four themes were proposed after a process of translating the meaning of text extracts from the findings sections across all the articles. The themes referred to the undermining influence of pain, its disempowering impact on all levels, unsatisfying relationships with health care professionals, and learning to live with the pain. The findings are dominated by wide-ranging distress and loss but also acknowledge self-determination and resilience. Implications of the meta-ethnography for clinicians and future qualitative research are outlined, including the need to study relatively unexamined facets of subjective experience such as illness trajectory and social identity.

A growing body of empirical research has confirmed an association between chronic pain and cognitive dysfunction. The aim of the present study was to determine whether cognitive function is affected in patients with a diagnosis of chronic neuropathic or radicular pain relative to healthy control participants matched by age, gender, and years of education. We also examined the interaction of pain with age in terms of cognitive performance. Some limitations of previous clinical research investigating the effects of chronic pain on cognitive function include differences in the pain and cognitive scale materials used, and the heterogeneity of patient participants, both in terms of their demographics and pathological conditions. To address these potential confounds, we have used a relatively homogenous patient group and included both experimental and statistical controls. We have also specifically investigated the interaction effect of pain and age on cognitive performance. Patients (n = 38) and controls (n = 38) were administered a battery of cognitive tests measuring IQ, spatial and verbal memory, attention, and executive function. Educational level, depressive symptoms, and state anxiety were assessed as were medication usage, caffeine, and nicotine consumption to control for possible confounding effects. Both the level of depressive symptoms and the state anxiety score were higher in chronic pain patients than in matched control participants. Chronic pain patients had a lower estimated IQ than controls, and showed impairments on measures of spatial and verbal memory. Attentional responding was altered in the patient group, possibly indicative of impaired inhibitory control. There were significant interactions between chronic pain condition and age on a number of cognitive outcome variables, such that older patients with chronic pain were more impaired than both age-matched controls and younger patients with chronic pain. Chronic pain did not appear to predict performance on the Wisconsin Card Sorting Task, which was used a measure of executive function. This study supports and extends previous research indicating that chronic pain is associated with impaired memory and attention.Perspective: Compared to healthy control participants, patients with chronic neuropathic or radicular pain showed cognitive deficits which were most pronounced in older pain patients.

Objective. The objective of the study was to collect data on the direct and indirect economic cost of chronic pain among patients attending a pain management clinic in Ireland.Setting. A tertiary pain management clinic serving a mixed urban and rural area in the West of Ireland.Design. Data were collected from 100 patients using the Client Services Receipt Inventory and focused on direct and indirect costs of chronic pain.Methods. Patients were questioned about health service utilization, payment methods, and relevant sociodemographics. Unit costs were multiplied by resource use data to obtain full costs. Cost drivers were then estimated.Results. Our study showed a cost per patient of US$24,043 over a 12-month period. Over half of this was attributable to wage replacement costs and lost productivity in those unable to work because of pain. Hospital stays and outpatient hospital services were the main drivers for health care utilization costs, together accounting for 63% of the direct medical costs per study participant attending the pain clinic.Conclusion. The cost of chronic pain among intensive service users is significant, and when extrapolated to a population level, these costs represent a very substantial economic burden.

These results suggest that responses to interventional pain management in chronic myofascial paraspinous pain may be influenced by psychological characteristics, especially pretreatment anxiety.

AimThis study set out to investigate whether cognitive coping strategies that match participants’ preferred coping style effectively reduce pain intensity and situational anxiety in a population of people with chronic pain.MethodChronic pain patients (N = 43) completed questionnaires on coping style, pain intensity, self-efficacy, and situational/trait anxiety. Participants were classified as Monitors (n = 16) or Blunters (n = 19) based on their Miller Behavioural Style Scale score. Participants were then provided with an audiotaped intervention in which they were instructed to focus on pain sensations or to engage in a distraction task and then to rate the pain intensity and their anxiety during and after the attentional focus and distraction conditions. The two interventions were each completed by all participants, having been presented in counterbalanced order.ResultsFindings revealed that Monitors’ level of anxiety decreased following a congruent (i.e., sensation-focused) intervention. No effects were obtained in terms of perceived pain. For blunters, however, their perceived levels of anxiety and pain did not attenuate following a congruent, distraction-focused intervention.ConclusionAmong persons experiencing chronic pain, tailoring coping strategies to match an individual’s preferred coping style–in particular, those with a high level of monitoring–may enhance the benefit of psychological approaches to management of anxiety.
