Abstract
PURPOSE Vocational rehabilitation (VR) is an intervention to improve return to work for patients with chronic musculoskeletal pain (CMP). However, a systematic overview of characteristics of referred patients or eligible for VR is lacking, which hinders comparability across studies. Objectives were (1) to describe characteristics of patients with CMP referred to and eligible for VR and (2) to identify factors that contribute to VR eligibility. METHODS This study used a multicenter, cross-sectional design. Data of self-reported questionnaires were obtained between 2013 and 2019 from care as usual of eight Dutch VR centers. Descriptive statistics were performed to describe sociodemographic, pain-related, and work-related characteristics. Logistic regression analysis was used to identify factors contributing to VR eligibility. RESULTS Data sets of n = 2970 referred patients were included. The mean age was 46 years and 60% were female. Low back (43%), neck (37%), and shoulder pain (34%) were most reported. 82% Worked in paid employment. The absenteeism rate was 85%, and 44% was partially absent. After multidisciplinary screening, 62.2% were eligible for VR. Persons most likely to be eligible for VR (OR < 1.20) were those having back or neck pain, whereas least eligible (OR < 0.80) were persons having pain in hand/fingers or pain in other regions, unemployed workers, and those referred by a 'other' medical specialists. All other factors contributed little or none to the model. CONCLUSIONS An extensive description of sociodemographic, pain-related, and work-related characteristics is presented for patients eligible for VR. Especially having back/neck pain and being an employee were associated with higher chance of eligibility for VR.

Acceptance and Fear-Avoidance Mediate Outcomes of Interdisciplinary Pain Rehabilitation Programs at 12-Month Follow-Up: A Clinical Registry-Based Longitudinal Cohort Study from the Swedish Quality Registry for Pain Rehabilitation (SQRP). J Pain Res 2024; 17:83-105. [PMID: 38196970 PMCID: PMC10775695 DOI: 10.2147/jpr.s438260] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 12/19/2023] [Indexed: 01/11/2024] Open
Abstract
Background Factors that influence outcomes of interdisciplinary pain rehabilitation programs (IPRP) are poorly known. It is unclear how outcomes are influenced by pain intensity, psychological distress, and coping strategies. Aim This clinical registry-based longitudinal cohort study has three aims: 1) to determine the relative importance of pain intensity, psychological distress, acceptance, and fear-avoidance for changes in three outcomes of IPRP at 12-month follow-up; 2) to investigate whether the effects of pain intensity and psychological distress on the three outcomes are mediated via acceptance and fear-avoidance; and 3) to determine whether sex is a moderator. Methods This study uses Patient-Reported Outcome Measures (PROMs) from specialist units reporting data (2008-2016) to the Swedish Quality Registry for Pain Rehabilitation (SQRP). Adult chronic pain patients (N = 1991) answered the PROMs (background, pain, psychological distress, coping, participation, and health-related quality of life (HRQoL)). Partial Least Squares Structural Equation Modelling (PLS-SEM) was used to explore the aims. Results Changes in acceptance (β:0.424-0.553; all P<0.001) were the strongest predictor of the three outcomes (changes in life control, interference, and HRQoL) at 12-month follow-up. The next strongest predictor was baseline acceptance (β: 0.177-0.233; all P<0.001) and changes in fear-avoidance (β: -0.152- -0.186; all P<0.001). Baseline pain intensity and psychological distress showed weak positive associations. Their effects on the three outcomes were mediated via acceptance aspects. Sex was not a moderator. Discussion and Conclusion Acceptance aspects (baseline and changes) were important predictors of IPRP outcomes. Changes in fear-avoidance were also important although to a lesser degree. Some of the effects of pain intensity and psychological distress on outcomes were mediated via acceptance at baseline. Future PLS-SEM analysis of real-world IPRP should include more potential mediators (eg, catastrophizing and more facets of psychological flexibility and fear-avoidance) and the components of IPRP.

Abstract
OBJECTIVES This study explored changes in pain-related parameters, occupational function, occupational balance, lifestyle factors, and self-perceived health status in adults with chronic high-impact pain participating in an occupational therapy lifestyle intervention. METHODS This one-group longitudinal feasibility study was performed in three continuous feasibility rounds. The occupational therapists-led intervention targeted meaningful occupations, regular physical activity, and a healthy diet. The intervention contained individual and group sessions and was added to the standard multidisciplinary chronic pain treatment. Outpatients (n=40, 85 % females, 46.6 ± 10.9 years old) participated in the study between April 2019 and December 2021. The analysis includes data for 31 participants. Analysis of pre-post changes assessed after each feasibility round were performed for the outcomes: pain intensity, pain sensitivity and pain modulation (pressure pain threshold and tolerance, temporal summation of pain and conditioned pain modulation), pain self-efficacy, pain catastrophizing, motor and process skills, occupational balance, daily wake-time movement, daily walking steps, body mass index, waist circumference, blood pressure, and self-perceived health status. RESULTS Improvements in motor skills (assessment of motor and process skills score=0.20 (1.37; 1.57), 95 % CI 0.01; 0.38) and temporal summation of pain (-1.19 (2.86; -1.67), 95 % CI -2.16; -0.22), but a decrease in pain tolerance (-7.110 (54.42; 47.32), 95 % CI -13.99; -0.22) were observed. Correlation analysis suggested moderate-to-very strong statistically significant relationships in several outcomes related to pain, health, pain coping, occupational balance, occupational functioning, body anthropometrics, and pain sensitivity. CONCLUSIONS This study suggested that the lifestyle intervention would benefit motor skills while effects on other outcomes were unclear in adults with chronic pain. To confirm the findings, a randomized trial evaluating effectiveness is needed. Ethical committee number: SJ-307 Reg. Clinicaltrials.gov: NCT03903900.

Abstract
PURPOSE Chronic pain (CP) acceptance is a major factor in determining the well-being of patients with chronic pain. The chronic pain acceptance questionnaire (CPAQ) was translated and validated into Arabic (CPAQ-Ar). METHODS 244 patients with CP completed the CPAQ-Ar, the Beck Depression Inventory-II (BDI-II), the short form health survey (SF-36), the Pain Catastrophizing Scale (PCS), the Pittsburgh Sleep Quality Index (PSQI), the Modified Fatigue Impact Scale (MFIS), and the Depression Anxiety Stress Scale 21 (DASS-21). 110 patients completed the CPAQ-Ar twice separated by two weeks to investigate test-retest reliability. RESULTS Cronbach's α was 0.902 while the intraclass correlation coefficient (ICC) was 0.917. The standard error measurement (SEM) was seven points while the minimal detectable change with 95% confidence interval (MDC95) was seventeen points. The CPAQ-Ar showed moderate to high correlations with the PCS, the BDI-II, the SF-36, the MFIS, the PSQI, and the DASS-21 indicating a good concurrent validity. Exploratory factor analysis confirmed that the CPAQ-Ar consists of two subscales. Better pain acceptance associated with male gender, older people, employed participants, low pain intensity, and single pain site. CONCLUSIONS The CPAQ-Ar is a valid and reliable tool for the measurement of pain acceptance in Arabic speaking patients with CP.

Healthcare-related factors influencing symptom persistence, deterioration, or improvement in patients with persistent somatic symptoms: A scoping review of European studies. J Psychosom Res 2023; 174:111485. [PMID: 37716128 DOI: 10.1016/j.jpsychores.2023.111485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 08/30/2023] [Accepted: 09/04/2023] [Indexed: 09/18/2023]
Abstract
OBJECTIVE This scoping review explored healthcare-related factors associated with symptom persistence, deterioration, or improvement in patients with persistent somatic symptoms (PSS) across Europe. METHODS Articles were systematically searched in PubMed, Web of Science, Cochrane Library, and PsycINFO by combining terms of PSS and healthcare-related factors. Studies published in English, German, Polish, or Dutch between 2000 and 2022 were included. Healthcare-related factors associated with PSS symptom course were investigated, and study quality assessed (Center for Evidence-Based Medicine Checklist, Newcastle-Ottawa Scale). RESULTS Of 8386 identified studies, 56 were included in the analysis. A significant knowledge gap was evident, as most studies lacked comprehensive healthcare descriptions with particularly unclear definitions of "treatments as usual" in RCTs. The only extractable healthcare factor according to Andersen's Behavioral Model was the treatment setting. Rates of PSS improvement split by care-levels were 38% in primary, 44% in secondary, 25% in mixed, and 71% in specialized care. Persistence rates were 57%, 50%, 75%, and 29% respectively. Deterioration was observed in 5% of primary and 6% of secondary care studies. Studies were skewed toward the United Kingdom, Germany, and the Netherlands. CONCLUSIONS This scoping review shed light on the association between care levels and symptom outcomes in PSS patients. However, limited information in the current studies constrained our exploration of associations with other factors and symptom outcomes. Important aspects, like care availability, referral processes, and insurance coverage, are yet to be elucidated. Addressing these gaps is pivotal for developing targeted treatments across Europe, ultimately enhancing PSS patients' outcomes.

Abstract
OBJECTIVES Smerteinfo.dk is a freely accessible Danish website containing research-based, up-to-date knowledge on chronic pain, written in lay language, with a focus on information, guidance and self-management tools, developed in collaboration between health professionals and persons with high-impact chronic pain. This mixed-method study explored experiences, perceived usability, and challenges of Smerteinfo among patients with high-impact chronic pain. METHODS Semi-structured interviews enabling thinking-aloud and participant observation while using Smerteinfo were performed in 11 patients with high-impact chronic pain. Survey data were collected three months after being invited to use Smerteinfo among 200 patients on waiting-list at a Pain Center in Denmark. RESULTS Three themes captured the depth and variation in patterns of experiences, usability and challenges using Smerteinfo during interviews: 1) Appreciated easy access to new knowledge yet strived for more personalized information, 2) Experienced incentives as well as challenges when navigating the website, and 3) Suggested earlier introduction to the website. Challenges concerned the unknown update frequency of the website, information consisting of mostly text and many links, lack of material to improve self-management and too general information. Survey data revealed that 87 % found the language in the articles easy to understand and 73 % could recognize themselves and their challenges in the articles. A proportion of the respondents reported improved understanding of their pain condition (56 %), improved coping (33 %), and that they had made changes in their everyday life after reading on the website (33 %). CONCLUSIONS Patients with high-impact chronic pain found Smerteinfo valuable. The results suggest attention towards spreading knowledge of the website to general practitioners, who could introduce the site at an earlier stage of illness. Continuously improving the site and expand the applicable tools based on scientific evidence and in collaboration with end-users are crucial to ensure the usability of the website in the future.

Abstract
OBJECTIVES Depression is prevalent among patients with chronic pain and may impact pain management. An accurate assessment is, however, complicated by overlapping symptoms. This study investigated how patients with high-impact chronic pain interpreted and responded to the Patient Health Questionnaire 9 (PHQ-9) to identify problematic items and causes hereof. MATERIALS AND METHODS Cognitive interviews using the Three-Step Test-Interview procedure were conducted during the completion of the PHQ-9 in 33 patients with high-impact chronic pain referred to interdisciplinary treatment. Responses were analyzed using 4 coding categories: (1) "congruent" (response consistent with intention); (2) "incongruent" (response not consistent intention); (3) "ambiguous" (response both congruent and incongruent or insufficient to evaluate congruency); and (4) "confused" (response with confused or misunderstood statements). Next, the content of responses to problematic items was analyzed to identify causes for noncongruency, and encountered response difficulties were identified across all items. RESULTS Three items (items 2, 6, and 9) performed as intended (>97% congruent responses), while 7 items (items 1, 3, 4, 5, 7, 8, and 10) were identified as problematic (<50% congruent responses). Problematic items had 1 or more issues: Responses were based on (1) pain-related issues or (2) other (non-pain) factors unrelated to depression, or item structure caused response difficulties due to wordings, reversion, or having 2 questions in 1. DISCUSSION Problematic items limit the construct validity of the PHQ-9, leaving an increased risk of inflated depression scores in high-impact chronic pain. Identified problems should guide future revisions to enhance validity and screening accuracy for the benefit of both research and clinical practice.

Abstract
Background Chronic pain is a major health problem worldwide but the limited knowledge of its underlying pathophysiology impairs the opportunities for diagnostics and treatment. Biomarkers of chronic pain are greatly needed to understand the disease and develop new targets for interventions and drug treatments, and potentially introduce more precise diagnostic procedures. Much evidence points to a neuroimmune pathology for many chronic pain conditions and that important neuroimmune biomarkers exist in the cerebrospinal fluid (CSF) of patients with chronic pain. Systematic collection of CSF in large cohorts of chronic pain patients and healthy volunteers has proven difficult, however. We established the Danish Pain Research Biobank (DANPAIN-Biobank) with the aim of studying potential neuroimmune and glia-related biomarkers of chronic pain. In this paper, we describe the methods and the study population of the DANPAIN-Biobank. Methods In this cross-sectional study, we included (I) participants with high-impact (HI) chronic pain from a tertiary, interdisciplinary pain center; (II) participants with osteoarthritic pain scheduled for arthroplasty surgery of the hip or knee at a regional hospital; and (III) pain-free volunteers. All participants completed a questionnaire assessing pain, functional impairment, anxiety, depression, and insomnia before samples of blood and CSF were extracted. Quantitative sensory tests were performed on participants with HI chronic pain and pain-free volunteers, and postoperative outcome scores were available on participants with osteoarthritic pain. Results Of the 352 participants included, 201 had HI chronic pain (of which 71% had chronic widespread pain), 81 had chronic osteoarthritic pain, and 70 were pain-free volunteers. Samples were handled uniformly, and CSF samples were frozen within 30 minutes. Conclusions We describe the content of the DANPAIN-Biobank, which is unique in terms of the number of participants (including pain-free volunteers), extensive clinical data, and uniformity in sample handling. We believe it presents a promising new platform for the study of neuroimmune and glia-related biomarkers of chronic pain.

Abstract
ABSTRACT The increasing demand for pain management and limited resources available highlight the need to measure treatment effectiveness. We analysed data collected at 75 specialist persistent pain services located in Australia and New Zealand to calculate overall treatment outcome for patients receiving care during 2014-2020. Socio-demographic and clinical information was provided for 23,915 patients, along with patient-reported measures assessing pain, pain interference, depression, anxiety, stress, pain catastrophizing and pain self-efficacy. Latent Class Analysis identified four distinct outcomes based on patients' pattern of responses across the assessment tools at treatment end. Group 1 (n=8,369, 35%) reported low/mild severity across all clinical domains at the end of care, while Group 4 (n= 7,081, 30%) were more likely to report moderate/high severity on all domains. Group 2 (n=1,991, 8%) reported low/mild pain with moderate/high psychological distress at treatment end, and Group 3 (n=6,474, 27%) reported moderate/high pain with low/mild psychological distress. Multi-variable logistic regression identified those factors associated with the different groups. In particular, factors most predictive of a poor (Group 4) vs. good outcome (Group 1) were unemployment (due to pain or other reasons), requiring an interpreter, widespread pain, pain of longer duration and attributing the pain to an injury at work. The results may allow identification of those most likely to benefit from the services currently provided, and inform development of alternative or enhanced services for those at risk of a poor outcome.

Abstract
OBJECTIVES To evaluate the feasibility and outcomes of an occupational therapy lifestyle intervention for adults living with chronic pain. DESIGN This one-group pre-post interventional study investigated the feasibility and outcomes of the Redesign Your Everyday Activities and Lifestyle with Occupational Therapy (REVEAL(OT)) intervention targeting meaningful activities and lifestyle. SETTINGS The occupational therapist-led intervention was added to standard multidisciplinary chronic pain treatment at a Danish pain centre. PARTICIPANTS Of the 40 adult participants aged 18-64 (mean 46.6±10.9 years old, 85% females, chronic pain duration ≥3 months), there were 31 completers. INTERVENTION Three feasibility rounds were carried out in 2019-2021. The intervention focused on meaningful activities, healthy eating habits and daily physical activity. Methods of didactical presentations, group discussions, personal reflection and experiential learning were used in the intervention composed both of individual and group sessions. OUTCOMES Primary outcomes were predefined research progression criteria evaluated by the red-amber-green method. Secondary outcomes measured pre-post changes in health-related quality of life and occupational performance and satisfaction. RESULTS The study demonstrated satisfactory programme adherence (77.5%), patients' self-perceived relevance (97%), timing and mode of delivery (97%) and assessment procedure acceptance (95%). No adverse events causing discontinuation occurred. Recruitment rate (n=5.7 monthly), retention (77.5%) and the fidelity of delivery (83.3%) needed improvement. We observed no improvement in health-related quality of life (mean=0.04, 95% CI -0.03 to 0.12) but positive change in occupational performance (mean=1.80, 95% CI 1.25 to 2.35) and satisfaction (mean=1.95, 95% CI 1.06 to 2.84). The participants reached the minimal clinically important difference for occupational performance (≥3.0 points in 13.8%) and satisfaction (≥3.2 points in 24.0%). CONCLUSIONS The REVEAL(OT) intervention was feasible to deliver and beneficial for the participants' occupational performance and satisfaction. The interventions' recruitment, retention and delivery strategies need optimisation in a future definitive trial. TRIAL REGISTRATION NUMBER NCT03903900.

Characteristics of Persons Seeking Care for Moderate to Severe Pain Due to Chronic Low Back Pain and Osteoarthritis: A Cross-Sectional Study. J Pain Res 2022; 15:1125-1139. [PMID: 35469249 PMCID: PMC9034864 DOI: 10.2147/jpr.s360314] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 03/30/2022] [Indexed: 01/03/2023] Open
Abstract
Purpose To assess the associations between pain severity or physical (pQoL) and mental (mQoL) health-related quality of life and disability status or health-care utilization among persons living with moderate/severe pain due to chronic low back pain (CLBP) or osteoarthritis (OA), who received treatments in Quebec’s tertiary care pain centers. Materials and Methods This retrospective study was carried out using the Quebec Pain Registry (Canada) from 2008 to 2014 and contains data on persons referred to tertiary pain management clinics. Participants were selected if they were diagnosed with CLBP (N = 2663) or OA (N = 139) of more than 3 months duration and of pain intensity ≥5 on the Numeric Rating Scale (0–10) and completed baseline questionnaires. Results Less than 5% of persons were hospitalized in the 6 months before their first visit at the pain clinic, and 11.9% and 18.9% of persons with OA and CLBP, respectively, had a pain-related emergency room (ER) visit. Less than 1/5 and more than 1/4 of persons with OA and CLBP were receiving disability benefits, respectively. Persons with CLBP who had visited the ER, those on disability and those receiving disability benefits, reported higher levels of pain severity, interference, and lower levels of mQoL (and pQoL for those on disability or receiving benefits) compared to those who did not consult the ER, those not on disability or not receiving disability benefits, respectively (all p < 0.05). For OA, disability status was the only variable associated with pain interference and QoL (all p < 0.05). Conclusion Pain severity, pain interference and mQoL were associated with health-care utilization and disability status in persons with CLBP. These results were globally not found among persons with OA, which might be due to smaller sample size or unique characteristics of this population.

Abstract
OBJECTIVES With the International Classification of Diseases 11th revision (classifying fibromyalgia as a primary pain disorder) soon to be implemented, the importance of pain physicians being able to identify patients with fibromyalgia is emphasized. The diagnostic criteria proposed in 2016 are based on self-reported pain distribution and symptom severity. The study aimed to evaluate the diagnostic accuracy of the 2016 diagnostic criteria for fibromyalgia applied in a population of patients with high impact chronic pain referred for pain rehabilitation. METHODS The study was performed as a diagnostic accuracy study at two Danish interdisciplinary pain rehabilitation centers, including 215 participants. All participants were evaluated clinically to identify patients with fibromyalgia. The diagnosis was based on expert opinion, but the minimum requirements were: (1) pain in all four body quadrants and axially for at least three months and (2) minimum 8 of 18 positive tender points. Participants filled in the fibromyalgia survey questionnaire, the patient version of the 2016 diagnostic criteria. Sensitivity, specificity, likelihood ratios, and positive and negative post-test probabilities were calculated using a clinical diagnosis of fibromyalgia as the reference standard. RESULTS Based on clinical diagnosis 45% of the participants were diagnosed with fibromyalgia; of these, only 19% had been diagnosed previously. The 2016 diagnostic criteria demonstrated a sensitivity of 88.5%, a specificity of 81.5%, a positive likelihood ratio of 4.79, a negative likelihood ratio of 0.14, a positive post-test probability of 79.4%, and a negative post-test probability of 10.2%. CONCLUSIONS Fibromyalgia was severely under-diagnosed among patients with high impact chronic pain referred to tertiary care in two pain rehabilitation centers in Denmark. The 2016 diagnostic criteria showed sufficient discriminatory properties suggesting that the fibromyalgia survey questionnaire can be used as a screening tool assisting the identification of fibromyalgia in this patient population.

Obstructive sleep apnea is common in patients with high-impact chronic pain - an exploratory study from an interdisciplinary pain center. Scand J Pain 2022; 22:106-117. [PMID: 34643073 DOI: 10.1515/sjpain-2021-0112] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 09/27/2021] [Indexed: 02/04/2023]
Abstract
OBJECTIVES Sleep disturbances are increasingly recognized as a major part of chronic pain pathology. Obstructive sleep apnea (OSA) is a common occurrence in patients with chronic pain attending specialized pain clinics, yet its prevalence remains unclear. Using screening tools such as the Berlin and STOP-BANG questionnaires may aid in early identification of OSA and improve clinical care. This study i) examined the frequency of OSA based on objective sleep monitoring in patients with high-impact chronic pain, ii) explored potential differences in self-reported pain and sleep characteristics between patients with and without OSA, and iii) tested the agreement between OSA classification based on objective assessment and two OSA screening questionnaires. METHODS A consecutive cohort of 90 patients (71 women and 19 men; mean age: 47.1 ± 11.0 years) referred for interdisciplinary pain treatment, underwent one night of sleep monitoring using portable respiratory polygraphy (RP), and suspected OSA was confirmed with polysomnography (PSG). Self-reported data on clinical pain (severity, pain drawings and health-related quality of life), sleep characteristics (sleep quality insomnia, sleepiness), and risk of OSA (Berlin and STOP-BANG questionnaires) were collected the day before RP assessment. RESULTS Forty-six (51.1%) patients were classified with OSA according to RP and verified with PSG. Twenty-eight patients (31.1%) had moderate or severe OSA (apnea-hypopnea index [AHI] >15). Patients with OSA reported lower sleep quality compared with patients without OSA. Scores on pain severity, disability, quality of life, insomnia and sleepiness were comparable between patients with and without OSA. Sensitivity and specificity were 78.6 and 45.2% respectively for the Berlin questionnaire, and 71.4 and 58.1% respectively for the STOP-BANG questionnaire. The agreement for both questionnaires with objective assessment was poor-to-fair. Both questionnaires had acceptable negative predictive values but low positive predictive values reducing the clinical utility to identify patients with low OSA-risk in this sample. CONCLUSIONS The current study demonstrates a high prevalence of OSA in patients with high-impact chronic pain referred to specialized pain treatment, however the clinical pain profiles were similar in patients with and without OSA. The Berlin and STOP-BANG questionnaires have poor specificity and low-to-fair agreement with RP/PSG questioning their clinical utility in identifying OSA in this sample.

The association of probable PTSD at baseline and pain-related outcomes after chronic pain rehabilitation: A comparison of DSM-5 and ICD-11 criteria for PTSD. Eur J Pain 2021; 26:709-718.

Abstract
BACKGROUND There is a high prevalence of posttraumatic stress disorder (PTSD) in patients with chronic pain. However, different patients are identified depending on the diagnostic system used. Moreover, it is unclear if the conceptualizations of PTSD are differently associated with outcomes of pain rehabilitation. Hence, the aims of the present study were first to explore the prevalence rates and diagnostic agreement of probable PTSD according to the ICD-11 and the DSM-5 screening tools (International Trauma Questionnaire [ITQ] vs. PTSD Checklist [PCL-5]), and secondly, to explore the associations of probable PTSD determined by ITQ and PCL-5 with psychological distress measures at baseline, and thirdly, the associations with pain and disability after pain rehabilitation adjusting for psychological covariates. METHODS A consecutive cohort of patients with chronic non-malignant pain (n = 152) referred to a Danish interdisciplinary pain center was assessed at baseline prior to their first visit and at follow-up three days after completed treatment. RESULTS The estimated probable PTSD baseline prevalence rates were 15.8% (ITQ) and 16.4% (PCL-5). However, the diagnostic agreement between the PCL-5 and the ITQ was only moderate (k = 0.64). Overall, compared to the ITQ probable PTSD according to the PCL-5 correlated more strongly with psychological distress. Only the ITQ was associated with poorer outcomes after rehabilitation, explaining alone 7-8% of the variance in disability and pain intensity adjusted for covariates. CONCLUSIONS The results underline the importance of taking the conceptualization and assessment of PTSD into consideration when investigating the impact of PTSD on pain rehabilitation. SIGNIFICANCE There is a high prevalence of probable PTSD in patients with chronic pain. However, different patients with probable PTSD are identified depending on the diagnostic system used. Although similar probable PTSD prevalence rates (about 16%) were found using DSM-5 and ICD-11 PTSD screening tools (PCL-5 and ITQ, respectively), the diagnostic agreement between the systems was only moderate (k = 0.64). At the same time, only probable PTSD estimated according to the ITQ and not the PCL-5 was a significant predictor of disability after pain rehabilitation.

Abstract
Neuropathic pain is frequent in the general population, with 7 to 10% of adults presenting with chronic neuropathic pain. To date, the gold standard to evaluate treatments is based on randomized controlled trials. Nonetheless, such design is run on a limited sample and for a limited period. Moreover, many treatments will never be compared directly in sufficiently large and representative populations. A way to overcome several of these limitations is to use real-world data. Indeed, the International Association for the Study of Pain (IASP) includes a special interest group focusing on pain registries and promoting the use of such approaches. In this short narrative review, several of the main chronic pain registries are presented. The strengths and weaknesses of this approach are presented. Indication bias is frequent in observational studies because the choice of treatment is generally influenced by the patients' characteristics. However, a propensity score can be computed to adjust for these differences. The use of propensity score is briefly explained. Some data specific to neuropathic pain are discussed.

A Cognitive Functional Therapy+ Pathway Versus an Interdisciplinary Pain Management Pathway for Patients With Severe Chronic Low Back Pain (CONFeTTI Trial): Protocol for a Pragmatic Randomized Controlled Trial. Phys Ther 2021; 101:6277052. [PMID: 34003285 PMCID: PMC8427714 DOI: 10.1093/ptj/pzab132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Revised: 02/26/2021] [Accepted: 04/22/2021] [Indexed: 11/23/2022]
Abstract
OBJECTIVE Chronic low back pain (cLBP) is the leading cause of disability. Interdisciplinary pain management is recommended for patients with severe/high-impact cLBP. Such programs are expensive, not easily accessible, and have limited effect; therefore, new cost-effective strategies are warranted. Cognitive functional therapy (CFT) has shown promising results but has not been compared with an interdisciplinary pain management approach. The primary aim of this randomized controlled trial is to investigate if a pathway starting with CFT including psychologist support (CFT+) with the option of additional usual care (if needed) is superior in improving disability and more cost-effective at 12 months compared with an interdisciplinary pain management pathway (usual care). METHODS This pragmatic, 2-arm, parallel-group randomized controlled trial will randomly allocate patients (n = 176) aged 18 to 75 years referred to an interdisciplinary pain center due to severe cLBP to 1 of 2 groups (1:1 ratio). Participants randomized to CFT+ will participate in a 3-month functional rehabilitation pathway with the option of additional usual care (if needed), and participants randomized to the interdisciplinary pain management pathway will participate in an individualized program of longer duration designed to best suit the individual's situation, needs, and resources. The primary outcome is the proportion of participants with an 8-point improvement in the Oswestry Disability Index score at 12 months. Exploratory outcomes are change in Oswestry Disability Index scores over time and an economic analysis of quality-adjusted life years using the 3-level version of the EuroQol EQ-5D. IMPACT The study evaluates the cost-effectiveness of CFT+ with the option of additional usual care (if needed) for individuals with severe cLBP. Findings can potentially improve future care pathways and reduce cost for the health care system.

Sleep disturbance in patients attending specialized chronic pain clinics in Denmark: a longitudinal study examining the relationship between sleep and pain outcomes. Scand J Pain 2021; 21:539-547. [PMID: 33838100 DOI: 10.1515/sjpain-2020-0155] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Accepted: 03/21/2021] [Indexed: 12/16/2022]
Abstract
OBJECTIVES Sleep disturbances are highly prevalent in patients with chronic pain. However, the majority of studies to date examining sleep disturbances in patients with chronic pain have been population-based cross-sectional studies. The aims of this study were to 1) examine the frequency of sleep disturbances in patients referred to two interdisciplinary chronic pain clinics in Denmark, 2) explore associations between sleep disturbances and pain intensity, disability and quality of life at baseline and follow-up, and 3) explore whether changes in sleep quality mediated the relationships between pain outcomes at baseline and pain outcomes at follow-up. METHODS We carried out a longitudinal observational study, examining patients enrolled in two chronic pain clinics assessed at baseline (n=2,531) and post-treatment follow-up (n=657). Patients reported on their sleep disturbances using the sleep quality subscale of the Karolinska Sleep Questionnaire (KSQ), their pain intensity using 0-10 numerical rating scales, their pain-related disability using the Pain Disability Index (PDI), and quality of life using the EuroQol-VAS scale. The average time between baseline and follow-up was 207 days (SD=154). RESULTS At baseline, the majority of patients reported frequent sleep disturbances. We found a significant association at baseline between self-reported sleep disturbances and pain intensity, pain-related disability, and quality of life, where greater sleep disturbance was associated with poorer outcomes. At follow-up, patients reported significant improvements across all pain and sleep outcomes. In two mediation models, we showed that changes in sleep disturbances from baseline to follow-up were significantly associated with (i) pain intensity at follow-up, and (ii) pain disability at follow-up. However, baseline pain intensity and disability scores were not associated with changes in sleep disturbances and, we did not find evidence for significant mediation of either pain outcome by changes in sleep disturbances. CONCLUSIONS Self-reported sleep disturbances were associated with pain outcomes at baseline and follow-up, with greater sleep disturbances associated with poorer pain outcomes. Changes in sleep quality did not mediate the relationships between baseline and follow-up scores for pain intensity and disability. These findings contribute to a growing body of evidence confirming an association between sleep and chronic pain experience, particularly suggestive of a sleep to pain link. Our data following patients after interdisciplinary treatment suggests that improved sleep is a marker for a better outcome after treatment.
