The Helping to End Addiction Long-term Initiative (NIH HEAL Initiative) is an aggressive trans-NIH effort to speed solutions to stem the national opioid public health crisis, including through improved pain management. Toward this end, the NIH HEAL Initiative launched a common data element (CDE) program to ensure that NIH-funded clinical pain research studies would collect data in a standardized way. NIH HEAL Initiative staff launched a process to determine which pain-related core domains should be assessed by every clinical pain study and what questionnaires are required to ensure that the data is collected uniformly. ⋯ The selection of core domains will ensure that valuable clinical pain data generated by the initiative is standardized, useable for secondary data analysis, and useful for guiding future research, clinical practice decisions, and policymaking. PERSPECTIVE: The NIH HEAL Initiative launched a common data element program to ensure that NIH-funded clinical pain research studies would collect data in a standardized way. Nine core pain domains and questionnaires to measure them were chosen for studies examining acute pain and chronic pain in adults and pediatric populations.

Neuropathic pain research and clinical care is limited in low- and middle-income countries with high prevalence of chronic pain such as Nepal. We translated and cross-culturally adapted the Self-report version of the Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS)-a commonly used, reliable and valid instrument to screen for pain of predominantly neuropathic origin (POPNO)-into Nepali (S-LANSS-NP) and validated it using recommended guidelines. We recruited 30 patients with chronic pain in an outpatient setting for cognitive debriefing and recruited 287 individuals with chronic pain via door-to-door interviews for validation. ⋯ The S-LANSS-NP is a comprehensible, unidimensional, internally consistent, and valid instrument to screen POPNO in individuals with chronic pain with predominantly low-levels of literacy for clinical and research use. PERSPECTIVE: This paper shows that the Nepali version of the S-LANSS is comprehensible, reliable and valid in adults with chronic pain and predominantly low-levels of literacy in rural Nepal. The study could potentially develop research and clinical care of neuropathic pain in this resource-limited setting where chronic pain is a significant problem.

Little is known about the mechanisms by which pain catastrophizing may be associated with opioid use outcomes. This study aimed to investigate the potential mediating role of beliefs about the appropriateness of pain medicines for pain treatment on the association between pain catastrophizing and prescription opioid use in a community chronic non-cancer pain (CNCP) sample. Individuals (N = 420) diagnosed with CNCP participated in a cross-sectional online self-report study with validated measures of pain medication beliefs, pain catastrophizing, and current prescription opioid use. ⋯ A similar pattern of findings was found for high-dose opioid use, with pain medication beliefs significantly mediating the pain catastrophizing-high-dose use association (CI = 0.006, 0.050). Pain medication beliefs are a potentially modifiable psychological mechanism by which pain catastrophizing is associated with opioid use, including high-dose use. These findings have important implications for personalizing prevention and treatment programs.

Observational Study
Chronic Pain Prevalence and Factors Associated with High Impact Chronic Pain following Total Joint Arthroplasty: An Observational Study.
Hip, knee, and shoulder arthroplasty are among the most frequently performed orthopaedic procedures in the United States. High impact and bothersome chronic pain rates following total joint arthroplasty (TJA) are unknown; as are factors that predict these chronic pain outcomes. This retrospective observational study included individuals that had a TJA from January 2014 to January 2020 (n = 2,638). ⋯ Increased risk of bothersome chronic pain included non-white race, shoulder arthroplasty, knee arthroplasty, current or past tobacco use, and being female. PERSPECTIVE: In this cohort more than 1/3rd of individuals reported high impact or bothersome chronic pain following TJA. Non-white race and knee arthroplasty were the only two variables associated with both chronic pain outcomes.

Pain interventions typically include effortful exercise and long-term treatment - ie, short-term costs (effort) with delayed benefit (improved pain and/or function). Thus, understanding if long-term pain influences decision-making in context of delays and effort is essential given clear relevance to treatment uptake and/or adherence. We evaluated delay and effort attitudes in those experiencing chronic pain (n = 391) and in pain-free controls (n = 263). ⋯ Data availability: Study materials are available here: https://osf.io/zexm7/?view_only=c9848597361c41808c612874da6f33b7. PERSPECTIVE: People with chronic pain make more short-sighted decisions (prefer less reward sooner) and decreased willingness to undertake effort (prefer less reward with little effort) for monetary gains than people without pain. Interventions targeting discounting behavior may help improve both uptake and adherence for evidence-based, effortful treatments, such as exercise.
