The National Institutes of Health (NIH) minimum dataset for chronic low back pain (CLBP) was developed in response to the challenge of standardizing measurements across studies. Although reference values are critical in research on CLBP to identify individuals and communities at risk of poor outcomes such as disability, no reference values have been published for the Quebec (Canada) context. This study was aimed to (1) provide reference values for the Canadian version of the NIH minimum dataset among individuals with CLBP in Quebec, both overall and stratified by gender, age, and pain impact stratification (PIS) subgroups, and (2) assess the internal consistency of the minimum data set domains (pain interference, physical function, emotional distress or depression, sleep disturbance, and PIS score). We included 2847 individuals living with CLBP who completed the baseline web survey of the Quebec Low Back Pain Study (age: 44.0 ± 11.2 years, 48.1% women) and were recruited through social media and healthcare settings. The mean score was 6.1 ± 1.8 for pain intensity. Pain interference, physical function, emotional distress or depression, sleep disturbance, and PIS scores were 12.9 ± 4.1, 14.4 ± 3.9, 9.8 ± 4.4, 13.0 ± 3.6, and 26.4 ± 6.6, respectively. Emotional distress or depression showed floor effects. Good-to-excellent internal consistency was found overall and by language, gender, and age subgroups for all domains (alpha: 0.81-0.93) and poor-to-excellent internal consistency for PIS subgroups (alpha: 0.59-0.91). This study presents reference values and recommendations for using the Canadian version of the NIH minimum dataset for CLBP that can be useful for researchers and clinicians.

Medications for preventive treatment of migraine reduce migraine frequency, usually measured by a reduction in monthly migraine days (MMD), but generally do not eliminate the need for acute treatment. To assess the economic impact of treatment-related reductions in frequency, methodological guidance recommends capturing cost differences along the spectrum of MMD.

No validated measure for pain self-efficacy in children and adolescents is currently available in the German language, and existing English versions have limitations. This study used a thorough development process to create the Scale for Pain Self-Efficacy (SPaSE) in both German and English languages. Scale development was based on self-efficacy theory, adapting items from existing self-efficacy measures, and review of patients' perspectives. The final version of the 11-item SPaSE was created with expert discussions and testing of content validity, comprehensibility and construct validity. The validation process consisted of exploratory factor analysis, testing of item characteristics, internal consistency and sensitivity to change in two German samples of children and adolescents with chronic pain (study 1: outpatient sample N=150, inpatient sample N=31). Cross-validation in a US sample (study 2: N=98) confirmed the one-factor structure, the sound psychometric properties and reliability of the SPaSE. Sum scores of the SPaSE were negatively correlated with pain-related disability, pain intensity, passive pain coping strategies and emotional distress, in line with previous research. The valid and reliable SPaSE can be used in clinical practice to monitor pain treatment progress, advances the field of pain self-efficacy research in Germany, and opens the door to comparative research in German and English samples.

Early, concurrent palliative care interventions in chronic obstructive pulmonary disease (COPD) are limited. Project EPIC (Early Palliative Care In COPD) is a multiphase mixed methods study working to fill this gap.

Adults with chronic pain who also report high pain intensity and disability are more likely to experience depression and anxiety symptoms. The current study examined changes in anxiety and depression symptoms after an internet-delivered pain management program based on baseline pain intensity and disability severity categories. In a secondary analysis of data from four randomised controlled trials (n = 1333), greater pain intensity and disability were associated with increased odds of elevated anxiety or depression symptoms at baseline. Treatment led to greater reductions in anxiety and depression symptoms compared to a waitlist control, and these improvements occurred irrespective of baseline pain intensity or disability severity. Those individuals who reported ≥ 30% improvements in pain intensity or disability at post-treatment were more likely to also report ≥ 30% improvements in psychological symptoms. Importantly, most participants who achieved ≥ 30% improvements in depression and anxiety had not experienced such improvements in pain intensity or disability. These findings suggest that emerging internet-delivered pain management programs can lead to reductions in psychological distress even when pain intensity and disability are severe or do not improve with treatment. This indicates the value of such treatments in treating distress and improving mental health in people with chronic pain.

Patients within the safety net, defined as gap healthcare services for un- or under-insured persons, disproportionately suffer high impact chronic pain. The purpose of this review was to examine pain-related outcomes from multidisciplinary programs for patients with chronic pain within the safety net. A scoping review was conducted based on the Arksey and O'Malley framework coupled with the Preferred Reporting Items for Systematic reviews and Meta-Analyses-Scoping Review checklist. CINAHL, MEDLINE, PubMed, and Google Scholar were searched for eligible articles published between January 1st, 2010 and December 31st, 2020. Grey literature was searched by typing relevant keywords into Google. Quantitative and qualitative outcomes were included. Data collected were charted and analyzed. Ten articles were included, with five demonstrating primarily quantitative results, three demonstrating primarily qualitative results, and the remaining two demonstrating primarily mixed results. Of the studies that utilized qualitative measures, themes included reduction in pain symptoms and the positive reception of a group-based pain management approach. Of the studies that employed quantitative measures, most demonstrated improvements in pain-related outcomes post-intervention, though not all statistically significant. Multidisciplinary pain programs may be of benefit to safety net patients with chronic pain. Further data collection is needed to determine the efficacy of these programs.
