RESUMO

The Global Task Force on Chronic Pain in HIV published seven research priorities in the field of HIV-associated chronic pain in 2019: (1) causes; (2) management; (3) treatment individualization and integration with addiction treatment; (4) mental and social health factors; (5) prevalence; (6) treatment cost effectiveness; and (7) prevention. The current study used a web-based survey to determine whether the research topics were aligned with the priorities of adults with lived experiences of HIV and chronic pain. We also collected information about respondents' own pain and treatment experiences. We received 311 survey responses from mostly US-based respondents. Most respondents reported longstanding, moderate to severe, multisite pain, commonly accompanied by symptoms of anxiety and/or depression. The median number of pain treatments tried was 10 (IQR = 8, 13), with medications and exercise being the most common modalities, and opioids being viewed as the most helpful. Over 80% of respondents considered all research topics either "extremely important" or "very important". Research topic #2, which focused on optimizing management of pain in people with HIV, was accorded the greatest importance by respondents. These findings suggest good alignment between the priorities of researchers and US-based people with lived experience of HIV-associated chronic pain.

RESUMO

Cognitive impairment and chronic pain are amongst the most prevalent neurological sequelae of HIV infection, yet little is understood about the potential bidirectional relationship between the two conditions. Cognitive dysfunction can occur in chronic pain populations whilst those with cognitive impairment can display modified responses to experimentally induced painful stimuli. To date, this has not been explored in HIV cohorts.This study aimed to identify any contribution of chronic pain to cognitive impairment in HIV and to determine differences in pain characteristics between those with and without cognitive dysfunction.This was an observational cohort study involving people living with HIV (n = 148) in the United Kingdom. Participants underwent validated questionnaire-based measurement of pain severity, interference and symptom quality as well as conditioned pain modulation and quantitative sensory testing. All participants completed a computer-based cognitive function assessment.Fifty-seven participants met the criteria for cognitive impairment and 73 for chronic pain. The cognitive impairment group had a higher prevalence of chronic pain (p = 0.004) and reported more neuropathic symptoms (p = 0.001). Those with chronic pain performed less well in emotional recognition and verbal learning domains. The interaction identified between chronic pain and cognitive dysfunction warrants further exploration to identify causal links or shared pathology.

RESUMO

INTRODUCTION: Remote consultations through phone or video are gaining in importance for the treatment of musculoskeletal pain across a range of health care providers. However, there is a plethora of technical options for practitioners to choose from, and there are various challenges in the adaptation of clinical processes as well as several special considerations regarding regulatory context and patient management. Practitioners are faced with a lack of high-quality peer-reviewed resources to guide the planning and practical implementation of remote consultations. OBJECTIVES: This Clinical Update seeks to provide practical guidance for the planning and implementation of remote consultations for the management and treatment of people with musculoskeletal pain. METHODS: Recommendations are based on a brief overview of the relevant research regarding phone and video consultations for musculoskeletal practice and derived from the literature, relevant guidelines, and practical experience. RESULTS: The technical feasibility of remote consultations for musculoskeletal complaints is good, patient satisfaction is high, and a growing body of evidence supports its comparative effectiveness to in-person consultations in some circumstances for improving pain and functioning. We consider in detail practical aspects such as the choosing of hardware and software, we touch on the legal and regulatory context, and we focus on the adaptation of clinical processes and communication. CONCLUSION: This Clinical Update draws together best-practice evidence in a practically applicable format, enabling therapists who are working with people with pain to directly apply this knowledge to their individual clinical settings and the requirements of their patients.

RESUMO

Antiretroviral therapy (ART) has significantly improved immune health and survival rates in HIV, but these outcomes rely on near perfect adherence. While many psychosocial factors are related to sub-optimal adherence, effectiveness of associated interventions are modest or inconsistent. The Psychological Flexibility (PF) model underlying Acceptance and Commitment Therapy (ACT) identifies a core set of broadly applicable transdiagnostic processes that may be useful to explain and improve non-adherence. However, PF has not previously been examined in relation to ART adherence. Therefore, this cross-sectional study (n = 275) explored relationships between PF and intentional/unintentional ART non-adherence in people with HIV. Adults with HIV prescribed ART were recruited online. Participants completed online questionnaires assessing self-reported PF, adherence and emotional and general functioning. Logistic regressions examined whether PF processes were associated with intentional/unintentional non-adherence. Fifty-eight percent of participants were classified as nonadherent according to the Medication Adherence Rating Scale, of which 41.0% reported intentional and 94.0% unintentional non-adherence. Correlations between PF and adherence were small. PF did not significantly explain intentional/unintentional non-adherence after controlling for demographic and disease factors. Further clarification of the utility of PF in understanding ART non-adherence is warranted using prospective or experimental designs in conjunction with more objective adherence measures.

RESUMO

OBJECTIVE: Psychosocial factors are related to pain and sex-related outcomes in provoked vulvodynia and possibly in mixed and spontaneous vulvodynia. However, a broader behavioral framework, such as the psychological flexibility model, has received limited attention in this context. Recently, additional psychosocial variables have also emerged that appear relevant to vulvodynia, including perceived injustice, body-exposure anxiety during intercourse, and unmitigated sexual communion. The present study applied network analysis to explore relations between psychological flexibility, newly emerging psychosocial variables relevant to vulvodynia, and their associations with vulvodynia outcomes. The study also explored potential differences across vulvodynia subtypes. DESIGN: An online cross-sectional study of 349 participants with vulvodynia (112 provoked, 237 spontaneous/mixed) was carried out. METHODS: Participants completed self-report questionnaires, including questions on pain and sexual outcomes, depression, facets of psychological flexibility, body-exposure anxiety during intercourse, unmitigated sexual communion, and perceived injustice. Networks were computed for the total sample and for provoked and mixed/spontaneous vulvodynia subsamples. RESULTS: Perceived injustice, pain acceptance, and depression were "central" factors among the included variables, in all models. Psychological flexibility processes were relevant for all networks. Depression was more central in the network for mixed/spontaneous vulvodynia; body-exposure anxiety during intercourse was most central for the provoked subtype. CONCLUSIONS: Among the included variables, perceived injustice, pain acceptance, depression, and psychological flexibility appear to be important in vulvodynia. As different factors are significant across subtypes, tailored treatment approaches are suggested.

RESUMO

OBJECTIVE: This study aimed to assess the feasibility of online Acceptance and Commitment Therapy for painful diabetic neuropathy in the United Kingdom and to determine if a larger randomized controlled trial testing treatment efficacy is justified. METHODS: Participants with painful diabetic neuropathy were recruited online and from hospital services. This was a single-arm study in which all participants received online Acceptance and Commitment Therapy. Participants completed questionnaires at baseline and three months post-treatment. Primary feasibility outcomes were recruitment, retention, and treatment completion rates. Secondary outcomes were pre- to post-treatment effects on pain outcomes and psychological flexibility. RESULTS: Of 225 potentially eligible participants, 30 took part in this study. Regarding primary feasibility outcomes, the treatment completion and follow-up questionnaire completion rates were 40% and 100%, respectively. Generally, at baseline those who completed the treatment, compared with those who did not, had better daily functioning and higher psychological flexibility. With respect to secondary outcomes, results from the completers group showed clinically meaningful effects at post-treatment for 100% of participants for pain intensity and pain distress, 66.7% for depressive symptoms, 58.3% for functional impairment, 41.7% for cognitive fusion, 66.7% for committed action, 58.3% for self-as-context, and 41.7% for pain acceptance. CONCLUSIONS: This preliminary trial suggests feasibility of recruitment and follow-up questionnaire completion rates, supporting planning for a larger randomized controlled trial. However, treatment completion rates did not achieve the prespecified feasibility target. Changes to the treatment content and delivery may enhance the feasibility of online Acceptance and Commitment Therapy for people with painful diabetic neuropathy on a larger scale.

RESUMO

OBJECTIVE: Diabetes mellitus is associated with a number of complications that can adversely impact patients' quality of life. A common and often painful complication is painful diabetic neuropathy. The aims of this study were to systematically review and summarize evidence from studies of psychological treatments and psychosocial factors related to painful diabetic neuropathy and assess the methodological quality of these studies. METHODS: Electronic databases, related reviews, and associated reference lists were searched. Summaries of participants' data relating to the efficacy of psychological treatments and/or to associations between psychosocial factors and outcomes in painful diabetic neuropathy were extracted from the included studies. The methodological quality of included studies was assessed using two standardized quality assessment tools. RESULTS: From 2,921 potentially relevant titles identified, 27 studies were included in this systematic review. The evidence suggests that depression, anxiety, sleep, and quality of life are the most studied variables in relation to pain outcomes in painful diabetic neuropathy and are consistently associated with pain intensity. The magnitude of the associations ranged from small to large. CONCLUSIONS: Research into psychosocial factors in painful diabetic neuropathy is unexpectedly limited. The available evidence is inconsistent and leaves a number of questions unanswered, particularly with respect to causal associations between variables. The evidence reviewed indicates that depression, anxiety, low quality of life, and poor sleep are associated with pain in painful diabetic neuropathy. The disproportionate lack of research into psychological treatments for painful diabetic neuropathy represents a significant opportunity for future research.

RESUMO

Objective: The purpose of this study was to examine the effectiveness of acceptance and commitment therapy (ACT) for older adults with chronic pain. Secondarily, we examined the associations between changes on processes of psychological flexibility and treatment outcome variables. Subjects: Participants were 60 adults with chronic pain age 65 and older selected from a larger consecutive sample of 928 adults of any age. All participants had longstanding pain that was associated with significant distress and disability. Methods: Participants completed measures of pain, functioning, and depression, and processes of psychological flexibility at baseline, immediately post-treatment, and at a 9-month follow-up. Treatment consisted of a 2- or 4-week residential program based on principles of ACT delivered by an interdisciplinary team. Treatment was designed to increase daily functioning by enhancing key processes of psychological flexibility, including openness, awareness, and committed action. Results: Participants showed significant improvements in functioning and mental health at posttreatment. Participants also showed significant increases in pain acceptance and committed action from pre- to post-treatment. Small effect sizes were observed for most treatment outcome and process variables in the pre-treatment to follow-up intervals; however, these improvements were not statistically significant. In secondary analyses, changes in facets of psychological flexibility were significantly associated with improvements in social functioning and mental health. Conclusion: This study supports the potential effectiveness of ACT for chronic pain among older adults. Future research is needed to determine how to maximize the impact of this treatment, particularly through greater impact on psychological flexibility.

RESUMO

OBJECTIVE: Over the past 50 years, the field of chronic pain has witnessed an evolution of psychological approaches with some notable success. Some of this evolution has included "mindfulness-based interventions" (MBIs), now regarded as having encouraging partial support for their effectiveness. However, several theoretical challenges remain that may inhibit the progress of MBIs. These challenges include a lack of clarity surrounding the mindfulness construct itself, the proliferation of purported underlying mechanisms arising from different theories, and limited evidence for the mechanisms through which MBIs work. The current conceptual review provides a critique of existing theoretical models of mindfulness that have been applied to understanding and treating chronic pain. DESIGN: A conceptual narrative review was conducted. SETTING: Treatment programs for people with chronic pain. PATIENTS: Individuals with any type of chronic pain. INTERVENTIONS: MBIs for chronic pain. OUTCOME MEASURES: Mindfulness-based mechanisms explored in relation to several domains of functioning. RESULTS AND CONCLUSIONS: Based on this assessment, a summary of available evidence for a particular contextual behavioral theory of "mindfulness"-psychological flexibility-is outlined. Findings show the need for further integration of existing mindfulness constructs to better guide development and evaluation of mindfulness-based treatment methods in the future.

RESUMO

BACKGROUND: Evidence supports the validity of individual components of the psychological flexibility model in the context of chronic pain. However, there is a need to test the inter-relationships amongst measures of individual components of psychological flexibility in a more integrative manner. In particular, research is needed to examine whether a model with discrete facets as proposed is indeed reflected in data from currently used assessment measures in people with chronic pain. PURPOSE: This cross-sectional study investigated the underlying structure of measures of processes of psychological flexibility amongst individuals with chronic pain and the associations between this measurement model and patient functioning. METHODS: Five-hundred and seventy-three adults with chronic pain completed measures of pain, physical and social functioning, mental health, depression and processes of psychological flexibility, including acceptance, cognitive defusion, decentering and committed action. Confirmatory factor analyses tested lower-order, higher-order and bifactor models to examine the structure of psychological flexibility process measures. RESULTS: A single general factor reflecting openness explained variability in items across all of the psychological flexibility process measures. In addition to this general factor, distinct decentering and committed action group factors emerged in the data. As expected, the general factor was strongly correlated with measures of social functioning, mental health and depression. CONCLUSIONS: Future research is needed to determine the most useful means by which the presence of the general factor can be reflected in the measurement and theory of psychological flexibility.

RESUMO

OBJECTIVE: At present, the potential benefits of psychologically oriented approaches to pain management for patients waiting to undergo medical interventions, such as neuromodulation, remain unclear. Therefore, this study aimed to examine the results of an interdisciplinary treatment based on principles of Acceptance and Commitment Therapy (ACT) delivered to a group of patients being considered for a neuromodulation procedure. DESIGN: Participants were 86 adults with chronic pain. All were referrals to a 2-week, interdisciplinary, residential pain management course for people being considered for a later neuromodulation procedure. Patients completed standard self-report measures of outcome and treatment process at the beginning and end of the 2-week treatment. Data on progression on the neuromodulation pathway were extracted from medical records. RESULTS: After the 2-week ACT-based interdisciplinary treatment, the majority of patients showed a clinically significant improvement on pain, depression, physical functioning, social functioning, and pain acceptance. Regression analyses indicated that change in pain acceptance related to improvements in depression, mental health, physical function, and social function. Results with regard to the trial of neuromodulation revealed that patients who did not proceed to the trial at their physician's request (n = 13) reported significantly worse depression and mental health, and lower levels of pain acceptance and committed action following the 2-week program compared with those who went for the trial. CONCLUSION: People seeking medical interventions to reduce pain appear able to benefit from an interdisciplinary treatment aimed to improve daily functioning and mental health through increased psychological flexibility.

RESUMO

PURPOSE: To examine rates and correlates of unemployment across distinct common chronic pain diagnoses. METHODS: Data were analyzed from a sample of 2,382 patients with chronic pain in the Quebec Pain Registry (QPR). Patients were grouped into the following diagnostic categories based on their primary pain diagnosis recorded in the QPR: musculoskeletal pain; myofascial pain; neuropathic pain, and visceral pain. Analyses were performed to examine the associations between pain diagnosis, patient demographics, pain intensity, depressive symptoms, and unemployment status. RESULTS: Pain diagnosis, age, marital status, education, pain intensity, and depressive symptoms were each significant unique predictors of unemployment status in a hierarchical logistic regression analysis; the addition of depressive symptoms in this model contributed to the greatest increment of model fit. CONCLUSIONS: Depressive symptoms are associated with unemployment across a number of common chronic pain conditions, even when controlling for other factors that are associated with unemployment in these patients. Depressive symptoms, as a modifiable factor, may thus be an important target of intervention for unemployed patients with chronic pain.

RESUMO

PURPOSE: The aim of the present study was to investigate the factors that influence the change in pain catastrophizing during the course of a physical therapy intervention for musculoskeletal injury. METHODS: 187 clients enrolled in a 7-week physical therapy intervention were divided into four mutually exclusive groups on the basis of a pre-treatment assessment: (1) clients whose pre-treatment catastrophizing scores and measures of mental health problems were below clinical threshold, (2) clients whose pre-treatment catastrophizing scores were above clinical threshold but who scores on measures of mental health problems were below clinical threshold, (3) clients whose pre-treatment catastrophizing scores were above clinical threshold and whose scores on measures of mental health problems were also above clinical threshold, and (4) clients whose pre-treatment catastrophizing scores were below clinical threshold but whose scores on measures of mental health problems were above clinical threshold. RESULTS: The most prevalent risk profile consisted of clients with high levels of pain catastrophizing and high mental health problems (37 %), followed by the low catastrophizing and low mental health problems profile (35 %), the high catastrophizing and low mental health problems profile (16 %), and low catastrophizing and high mental health problems profile (10 %). Clients were considered non-responders if their post-treatment catastrophizing score remained above clinical threshold following treatment. Chi square analyses revealed a significantly higher proportion of non-responders in the high catastrophizing and mental health problem group than in any other group. CONCLUSIONS: The presence of mental health symptoms markedly reduces the effectiveness of physical therapy for reducing catastrophizing scores. The 'risk value' of high catastrophizing scores thus appears to vary as a function of the presence or absence of mental health symptoms. The findings argue for the inclusion of measures of mental health problems in the routine screening of individuals treated in physical therapy.

RESUMO

ABSTRACT: Stigma is common in people experiencing chronic pain and there are indications that it may adversely affect pain outcomes. However, to date, there is no systematic review exploring the impact of stigma on chronic pain-related outcomes. This systematic review and meta-analysis aimed to examine the association between stigma and key chronic pain outcomes and differences in stigma between pain conditions. Seven databases were searched for studies reporting a measure of association between stigma and at least one pain outcome in adults with chronic pain. Studies were screened by 2 independent researchers. Nineteen studies met eligibility criteria and data were extracted, quality-assessed, and narratively synthesised and meta-analysed where possible. Meta-analyses of bivariate cross-sectional correlations demonstrated significant positive correlations between stigma and pain intensity, disability, and depression, with small to moderate effects. Data from 2 prospective studies and those only reporting multivariate analyses that were not included in meta-analyses further supported these findings. There was some evidence that individuals who experience pain conditions with less clear pathophysiology may report greater stigma, although more research is needed. The review highlights that there is a growing number of studies on stigma in the pain field showing an adverse association between stigma and chronic pain outcomes.

RESUMO

Introduction: Stigma adversely affects people with chronic pain. The qualities within self-compassion may be particularly useful for buffering the impact of stigma on people with pain. In the context of an Acceptance and Commitment Therapy-based (ACT) treatment for chronic pain, this study investigated the association between changes in stigma and self-compassion and pain outcomes, and the potential moderating role of self-compassion on the association between stigma and pain outcomes. Materials and methods: Five-hundred and nineteen patients completed standardized self-report questionnaires of stigma, self-compassion, psychological flexibility, pain intensity and interference, work and social adjustment, and depression symptoms at the start of an interdisciplinary ACT-based treatment for chronic pain. The same measures were completed at post-treatment (n = 431). Results: The results indicated that key pain outcomes and self-compassion significantly improved during treatment, but stigma did not. Changes in stigma and self-compassion were significantly negatively correlated and changes in these variables were associated with improvements in treatment outcomes. There were significant main effects of stigma and self-compassion for many of the pre- and post-treatment regression models when psychological flexibility was not controlled for, but self-compassion did not moderate the association between stigma and pain outcomes. Stigma remained significant when psychological flexibility variables were controlled for, while self-compassion did not. Discussion: The findings add to our conceptual understanding of the inter-relationships between stigma, self-compassion, and psychological flexibility and can contribute to treatment advancements to optimally target these variables.

RESUMO

Background: Pain is the prominent feature of sickle cell disease (SCD) and negatively affects quality of life. Delivery of pain management programmes (PMPs) has been suggested in clinical guidelines for pain management in SCD; however, further evidence of the feasibility and effectiveness of PMPs in this population is needed. This study explored the feasibility of delivering a sickle cell pain management programme (SCPMP) for adults within a haemoglobinopathies service. Methods: A single arm, repeated-measures observational design was used to determine feasibility of delivering the SCPMP at one study site. Primary feasibility outcomes were recruitment, completion of treatment and outcome measures, satisfaction, credibility and acceptability to participants. Secondary feasibility outcomes were treatment outcomes and processes, frequency of vaso-occlusive crisis (VOC) and healthcare utilisation. Results: Four of five feasibility criteria were met. Annual recruitment of eight participants to a SCPMP was not achieved. Twenty-nine people began a SCPMP during the study period. Twenty-five (86.2%) participants attended ≥5/8 sessions and 21(84%) programme completers provided all end of programme questionnaires. Mean scores of >7 on ten-point scales were seen across satisfaction and credibility questions. At least moderate (Hedges g >0.5) effect sizes were seen in pre-post SCPMP measures of pain interference, anxiety, depression, self-efficacy, pain-related worry and acceptance. A small (Hedges g 0.4) effect size was seen in HRQoL. Following SCPMP attendance, mean frequency of self-reported VOC and hospital admissions reduced. Conclusions: This study suggests that, given an adequate source of referrals, a SCPMP is feasible to deliver and appears acceptable and credible to participants. Exploration of influences on recruitment, such as barriers to group interventions, would be illuminating, prior to investigating feasibility of an adequately powered randomised-controlled trial.

RESUMO

Autotaxin (ATX) catalyzes the conversion of lysophosphatidyl choline (LPC) to lysophosphatidic acid (LPA). Both ATX and LPA have been linked to pathophysiologies ranging from cancer to neuropathic pain. Inhibition of LPA production by ATX is therefore of therapeutic interest. Here we report the application of previously-developed, subsite-targeted pharmacophore models in a screening workflow that involves either docking or binary QSAR as secondary filters to identify ATX inhibitors from previously unreported structural types, four of which have sub-micromolar inhibition constants. Cell-based assays demonstrate that ATX inhibition and cytotoxicity structure-activity-relationships (SAR) exhibit selectivity cliffs, characterized by structurally similar compounds exhibiting similar biological activities with respect to ATX inhibition but very different biological activities with respect to cytotoxicity. Thus, general cytotoxicity should not be used as an early filter to eliminate candidate ATX inhibitor scaffolds from further SAR studies. Assays using two substrates of vastly different sizes demonstrate that the tools developed to identify compounds binding outside the central core of the active site did identify compounds acting at an allosteric site. In contrast, tools developed to identify active-site directed compounds did not identify active-site directed compounds. The stronger volume overlap imposed when selecting screening candidates expected to bind outside the active site is likely responsible for the stronger match between intended and actual target site.

RESUMO

PURPOSE: Emerging evidence suggests that perceptions of injustice negatively impact return to work following whiplash injury. The Injustice Experiences Questionnaire (IEQ) is a recently developed measurement tool that may be used to assess injury-related perceptions of injustice following injury. To date, although research has supported the predictive validity of the IEQ, a clinical cut off for interpreting this measure has not been established. Increased support for the validity and clinical interpretation of the IEQ represents a first step towards identifying patients that might benefit from targeted intervention to mitigate the impact of perceived injustice. METHODS: The IEQ was completed by 103 whiplash-injured patients upon commencement and completion of a standardized multidisciplinary rehabilitation program. One year later, individuals reported on their employment activity, pain severity, and use of narcotics. A receiver operating characteristic (ROC) curve analysis was conducted to identify the post-treatment IEQ score that was optimally associated with unemployment status at the follow-up. Secondary ROC curve analyses examined IEQ scores best associated with high pain severity and narcotic use 1 year following treatment. RESULTS: Results indicated that IEQ scores significantly discriminated individuals who returned and did not return to work at the follow-up. An IEQ score of 19 optimally identified participants in terms of follow-up employment status. IEQ scores at the end of treatment also discriminated individuals with high and low pain severity ratings and narcotic use status at the follow-up. Post-treatment IEQ scores of 18 and 20 optimally identified participants who had high pain severity ratings and who were using narcotics at the follow-up, respectively. CONCLUSIONS: These results further support the validity of the IEQ and provide a guideline for its clinical interpretation in patients with persistent pain and disability following musculoskeletal injury. IEQ scores above the identified cut off may represent a barrier to work return and may warrant targeted intervention.

RESUMO

Making sense of one's circumstances is normally regarded as helpful, including in the context of chronic pain. However, sense-making may be associated with adverse impacts in daily functioning. To better understand the functions of sense-making, the objective of the current study was to develop, validate, and preliminarily examine a measure of potentially helpful and unhelpful forms of sense-making behavior in people seeking treatment for chronic pain. This measure is called the Sense Making Questionnaire (SMQ). Research participants included 451 adults consecutively attending a specialty interdisciplinary treatment for chronic pain. Data for this study derived from a standard set of measures participants completed prior to treatment. Exploratory Factor Analysis (EFA) produced a 3-factor solution based on 15 items, including Avoidance of Incoherence, Overthinking, and Functional Coherence. The first 2 of these factors and the total achieved adequate internal consistency. Construct validity of the SMQ scores was supported by significant correlations with measures of pain acceptance, committed action, cognitive fusion, and intolerance of uncertainty. The SMQ total score correlated significantly with pain interference, r = .23, depression, r = .41, and work and social adjustment, r = .30, all P < .001. In multiple regression analyses the total score also significantly predicted depression after age, gender, education, pain duration, pain intensity, and pain acceptance were statistically controlled, and it accounted for an additional 8.0% in explained variance. It appears that there is a distinction between literal coherence and functional coherence. In some situations, it may benefit people with chronic pain to shift focus from efforts to make literal sense of pain and instead to keep the focus on taking effective action even if this does not appear at first to make sense. PERSPECTIVE: This study in people seeking treatment for chronic pain includes development of a measure of behavior patterns related to making sense in chronic pain. It shows that sometimes these behavior patterns can be ineffective, as they appear negatively associated with emotional, physical, and social functioning.

RESUMO

Background: The provision of pain management programmes (PMPs) changed substantially in response to the COVID-19 pandemic with virtual delivery implemented in many services. Little is known about patient selection processes for virtual PMPs and how this might differ from in-person programmes. The aim of this audit was to document the patient selection process for PMPs at a speciality pain service prior to and during the pandemic. Methods: This retrospective audit used data from consecutive patients attending a multidisciplinary assessment to determine the suitability of a PMP. Anonymized data were extracted from assessment letters and hospital records in the months prior to the pandemic (n =168) and during the start of the pandemic once the service began delivering virtual PMPs (n =171). Results: For the standard pain management pathway, most patients were offered a PMP option within the service before and during the pandemic, although a greater proportion of patients were offered treatment during the pandemic. For the neuromodulation pathway, most patients were offered a pre-neuromodulation PMP option, and this was similar before and during the pandemic. Psychosocial complexities and unwillingness to engage in a pain management approach that does not principally focus on pain reduction were the most common reasons that patients were not offered a programme. Discussion: This audit points to a pattern of more inclusive assessment outcomes within our service over time and particularly during the pandemic. Offering a range of in-person and virtual PMPs can meet a wider range of patient need. Research is needed to understand how to best assess and match patients with the breadth of treatment delivery formats now available.
