Abstract: Persistent opioid use (POU) is a common marker of harm related to opioid use after trauma. This study determined the incidence and risk factors for POU after hospitalisation due to trauma in New Zealand, among opioid-naïve patients. This was a population-based, retrospective cohort study, using linked data, involving all trauma patients of any age admitted to all NZ hospitals between 2007 and 2019. We included all patients who received opioids after discharge and were considered opioid naïve, defined as not having received opioids or not having a prior diagnosis of opioid-use disorder up to 365 days preceding the discharge date. The primary outcome was the incidence of POU defined as opioid use after discharge between 91 and 365 days. We used a multivariable logistic regression to identify independent risk factors for POU. A total of 177,200 patients were included in this study. Of these, 15.3% (n = 27,060) developed POU based on criteria used for the primary analysis, with sensitivity analyses showing POU incidence ranging from 14.3% to 0.8%. The opioid exposure risk factors associated with POU included switching between different opioids (adjusted odds ratio [aOR] 2.62; 95% confidence interval [CI] 2.51-2.73), prescribed multiple opioids (vs codeine, aOR 1.44; 95% CI 1.37-1.53), slow-release opioid formulations (aOR 1.32; 95% CI 1.26-1.39), and dispensed higher total doses of on the initial discharge prescription (aOR 1.26; 95% CI 1.20-1.33). Overall, 1 in 7 opioid-naïve patients who were exposed to opioids after trauma developed POU. Our findings highlight clinicians should be aware of these factors when continuing opioids on discharge.
摘要:持续使用阿片类药物(POU)是创伤后使用阿片类药物造成伤害的常见标志。本研究确定了新西兰因外伤住院的阿片类药物无效患者中持续使用阿片类药物的发生率和风险因素。这是一项基于人群的回顾性队列研究,使用的是关联数据,涉及 2007 年至 2019 年期间新西兰所有医院收治的所有年龄段的外伤患者。我们纳入了出院后接受阿片类药物治疗的所有患者,这些患者被认为是阿片类药物新患者,即在出院前365天内未接受过阿片类药物治疗或之前未被诊断出患有阿片类药物使用障碍。主要结果是 POU 的发生率,定义为出院后 91 天至 365 天内阿片类药物的使用情况。我们使用多变量逻辑回归来确定 POU 的独立风险因素。本研究共纳入了 177200 名患者。根据主要分析使用的标准,其中 15.3% 的患者(n = 27,060 人)出现了 POU,而敏感性分析显示 POU 的发生率在 14.3% 到 0.8% 之间。与 POU 相关的阿片类药物暴露风险因素包括:在不同阿片类药物之间转换(调整后比值比 [aOR] 2.62;95% 置信区间 [CI] 2.51-2.73)、开具多种阿片类药物处方(与可待因相比,aOR 1.44;95% CI 1.37-1.53)、使用缓释阿片类药物制剂(aOR 1.32;95% CI 1.26-1.39),以及首次出院处方总剂量较高(aOR 1.26;95% CI 1.20-1.33)。总体而言,在创伤后接触过阿片类药物的阿片类药物无效患者中,每7人中就有1人出现POU。我们的研究结果表明,临床医生在出院后继续使用阿片类药物时应注意这些因素。

Abstract: A recent Lancet Commission raised concerns about the management of child and adolescent pain. We aimed to undertake a comprehensive review of qualitative research to understand children and adolescent pain experiences across contexts. We used the 7 stages of meta-ethnography to synthesise findings. We combined the strengths of arts-based methods, translating themes into poems in a range of languages. We screened 7471 titles, 464 abstracts, and 302 full texts, including 189 reports (177 unique samples) incorporating 5875 young people. Age range across studies was 2 to 38 years, with 93% including those between the age of 11 and 20 years old. Studies spanned 30 years (1993-2023) with 121 (64%) published in the last 10 years. Almost all (93%) were set-in high-income countries. We report 6 themes focusing on transition to adulthood: (1) I want to stay within the safety of home; (2) don't exclude me from my own care; (3) it might hurt but it's for my own good; (4) I rely on others but I want some independence; (5) I am no longer a child but I am not an adult yet; and (6) I wasn't prepared for the transfer to adult health care. Our findings focus on the complex transition into adulthood and the importance of creating a genuine healthcare partnership with young people by acknowledging their perspectives, creating a safe and supportive environment, and preparing them for the transition to adult pain care. Arts-based methods have the potential to make findings from qualitative evidence syntheses accessible and impactful for compassionate health care.

Abstract: Using the Australiasian electronic Persistent Pain Outcomes Collaboration, a binational pain registry collecting standardized clinical data from paediatric ePPOC (PaedsePPOC) and adult pain services (AdultePPOC), we explored and characterized nationally representative chronic pain phenotypes and associations with clinical and sociodemographic factors, health care utilization, and medicine use of young people. Young people ≥15.0 and <25.0 years captured in PaedePPOC and AdultePPOC Australian data registry were included. Data from 68 adult and 12 paediatric pain services for a 5-year period January 2018 to December 2022 (first episode, including treatment information) were analysed. Unsupervised latent class analysis was applied to explore the existence of distinct pain phenotypes, with separate models for both services. A 3-phenotype model was selected from both paediatric and adult ePPOC data, with 693 and 3518 young people included, respectively (at least one valid indicator variable). Indicator variables for paediatric models were as follows: pain severity, functional disability (quasisurrogate "pain interference"), pain count, pain duration, pain-related worry (quasisurrogate "catastrophizing"), and emotional functioning; and, for adult models: pain severity, pain interference, pain catastrophizing, emotional functioning, and pain self-efficacy. From both services, 3 similar phenotypes emerged ("low," "moderate," "high"), characterized by an increasing symptom-severity gradient in multidimensional pain-related variables, showing meaningful differences across clinical and sociodemographic factors, health service utilization, and medicines use. Derived phenotypes point to the need for novel care models that differentially respond to the needs of distinct groups of young people, providing timely, targeted, age-appropriate care. To effectively scale such care, digital technologies can be leveraged to augment phenotype-informed clinical care.

Abstract: The concept "nociplastic pain" has been developed for patients with features of nociceptive system sensitization that are not explained as nociceptive or neuropathic. Here, we tested how well the recently published grading system differentiates between chronic primary and secondary pain conditions. We recruited patients with fibromyalgia (FMS, n = 41), complex regional pain syndrome (CRPS, n = 11), osteoarthritis (OA, n = 21), or peripheral nerve injury (PNI, n = 8). We used clinical history, pain drawings, quantitative sensory testing (QST), and questionnaires to classify their pains as possibly or probably "nociplastic." All patients with chronic primary pain exhibited widespread/regional pain not explainable by either nociceptive or neuropathic mechanisms. Widespread pain occurred in 12 patients with OA but was identified as nociceptive in 11 of 12. Regional pain occurred in 4 patients with PNI but was identified as neuropathic in 3 of 4. At this step, the grading system had 100% sensitivity and 93% specificity. Clinical evidence for pain hypersensitivity by QST, and history of hypersensitivity and mental comorbidities did not differentiate between chronic primary pain (QST: 36/52 = 69%, history: 43/52 = 83%) and secondary pain conditions (QST: 20/29 = 69%, history: 24/29 83%). Based on these data, specificity remained excellent (93%), but sensitivity dropped substantially (60%) due to lacking evidence for pain hypersensitivity in many patients with FMS. This low sensitivity suggests that the published grading system is not suitable for screening purposes. We suggest structural and content modifications to improve sensitivity, including placement of patient history before clinical examination and addition of a high tender point count as evidence for widespread pain hypersensitivity.

Abstract: No comparative effectiveness data exist on nonopioid analgesics and nonbenzodiazepine anxiolytics to treat pain with anxiety. We examined the relationship between drug class and central nervous system (CNS) active drug polypharmacy on pain and anxiety levels in Medicare enrollees receiving home health (HH) care. This retrospective cohort study included enrollees with diagnoses and 2+ assessments of pain and anxiety between HH admission and discharge. Three sets of linear regression difference-in-reduction analyses assessed the association of pain or anxiety reduction with number of drugs; drug type; and drug combinations in those with daily pain and daily anxiety. Logistic regression analysis assessed the effect of medication number and class on less-than-daily pain or anxiety at HH discharge. A sensitivity analysis using multinomial regression was conducted with a three-level improvement to further determine clinical significance. Of 85,403 HH patients, 43% received opioids, 27% benzodiazepines, 26% gabapentinoids, 32% selective serotonin reuptake inhibitors, and 8% serotonin and norepinephrine reuptake inhibitors (SNRI). Furthermore, 75% had depression, 40% had substance use disorder diagnoses, and 6.9% had PTSD diagnoses. At HH admission, 83%, 35%, and 30% of patients reported daily pain, daily anxiety, and both, respectively. Central nervous system polypharmacy was associated with worse pain control and had no significant effect on anxiety. For patients with daily pain plus anxiety, pain was best reduced with one medication or any drug combination without opioid/benzodiazepine; anxiety was best reduced with combinations other than opiate/benzodiazepine. Gabapentinoids or SNRI achieved clinically meaningful pain control. Selective serotonin reuptake inhibitors provided clinically meaningful anxiety relief.

Abstract: Transcranial direct current stimulation (tDCS) is a noninvasive neuromodulatory technique with the potential to provide pain relief. However, tDCS effects on pain are variable across existing studies, possibly related to differences in stimulation protocols and expectancy effects. We investigated the independent and joint effects of contralateral motor cortex tDCS (anodal vs cathodal) and socially induced expectations (analgesia vs hyperalgesia) about tDCS on thermal pain. We employed a double-blind, randomized 2 × 2 factorial cross-over design, with 5 sessions per participant on separate days. After calibration in Session 1, Sessions 2 to 5 crossed anodal or cathodal tDCS (20 minutes 2 mA) with socially induced analgesic or hyperalgesic expectations, with 6 to 7 days between the sessions. The social manipulation involved videos of previous "participants" (confederates) describing tDCS as inducing a low-pain state ("analgesic expectancy") or hypersensitivity to sensation ("hyperalgesic expectancy"). Anodal tDCS reduced pain compared with cathodal stimulation (F(1,19.9) = 19.53, P < 0.001, Cohen d = 0.86) and analgesic expectancy reduced pain compared with hyperalgesic expectancy (F(1,19.8) = 5.62, P = 0.027, Cohen d = 0.56). There was no significant interaction between tDCS and social expectations. Effects of social suggestions were related to expectations, whereas tDCS effects were unrelated to expectancies. The observed additive effects provide novel evidence that tDCS and socially induced expectations operate through independent processes. They extend clinical tDCS studies by showing tDCS effects on controlled nociceptive pain independent of expectancy effects. In addition, they show that social suggestions about neurostimulation effects can elicit potent placebo effects.

However, tDCS effects on pain are variable across existing studies, possibly related to differences in stimulation protocols and expectancy effects.
