Associations Between Adolescent Chronic Pain and Prescription Opioid Misuse in Adulthood

Exploring academic achievement and relevant risk factors among a community sample of adolescents with chronic pain compared to peers

OBJECTIVE

To compare adolescents in the United Kingdom with chronic pain with their peers in relation to psychological and behavioral outcomes (i.e., mental health, bullying, substance use) and academic achievement.

METHODS

Participants were adolescents with chronic pain (n = 856) and peers without chronic pain (n = 3,093) from the Avon Longitudinal Study of Parents and Children (ALSPAC) who attended a research clinic in the United Kingdom at 17 years and completed data collection at multiple timepoints. Chi-square and t-tests were used to explore group differences across psychological and behavioral measures. Regression and mediation analyses examined the relationship between chronic pain and academic achievement measures, including the derived variables of pathway to higher education and educational qualifications.

RESULTS

Adolescents with chronic pain were found to experience more difficulties with mental health, bullying, and substance use. Additionally, a relationship between chronic pain and reporting a pathway to higher education was found after key variables were accounted for, although group differences were not observed across other academic achievement measures. Further analyses identified a moderate indirect effect of chronic pain on reporting a pathway to higher education when mediated by sleep difficulties.

CONCLUSIONS

The limited predictive relationship between chronic pain and academic achievement potentially indicates that, despite struggling more with factors such as mental health, bullying, and substance use, adolescents with chronic pain may utilize enhanced skills in maintaining a developmental trajectory at school or external factors such as support from their caregivers or school. The complex interrelationship between sleep and chronic pain is also an important consideration for the ability to achieve academically.

Extended Reality (XR) in Pediatric Acute and Chronic Pain: Systematic Review and Evidence Gap Map

BACKGROUND

The use of extended reality (XR), including virtual reality (VR) and augmented reality (AR), for treating pain has accelerated in the last 10 years. XR is an attractive biobehavioral intervention that may support management of pain or pain-related disability. Reviews of the literature pertaining to adults report promising results, particularly for acute procedural pain.

OBJECTIVE

This study aimed to (1) summarize the available evidence with respect to feasibility, safety, and effectiveness (pain intensity) of XR for pediatric acute and chronic pain; (2) summarize assessment tools used to measure study outcomes; and (3) identify gaps in evidence to guide future research efforts.

METHODS

This study is a systematic review of the literature. Multiple databases (CINAHL, Cochrane Central, Embase, MEDLINE, PsycINFO) were searched from inception until March 2023. Titles, abstracts, and full-text articles were reviewed by 2 team members to determine eligibility. Articles were included if the (1) participants were aged 0 to 18 years; (2) study intervention was VR or AR; (3) study outcomes included safety, feasibility, acceptability, or effectiveness on the outcome of pain; and (4) study design was observational or interventional. Data were collected on bibliographic information; study characteristics; XR characteristics; outcome domains; outcome measures; and study findings pertaining to safety, feasibility, and effectiveness.

RESULTS

We included 90 articles in the review. All included studies used VR, and 93% (84/90) studied VR in the context of acute pain. Of the 90 studies, 74 studies were randomized trials, and 15 studies were observational. Safety was assessed in 23 studies of acute pain, with 13 studies reporting no adverse events and 10 studies reporting events of low concern. Feasibility was assessed in 27 studies. Of the 84 studies of acute pain, 62% (52/84) reported a positive effect on pain intensity, 21% (18/84) reported no effect, and 13% (11/84) reported mixed effects. All 6 studies of chronic pain reported a positive effect on pain intensity. An evidence gap map was used to illuminate gaps in specific research areas stratified by subtypes of pain. Risk of bias assessment revealed 67 studies had a moderate risk of bias, 17 studies had a high risk, and 5 studies were deemed to be low risk.

CONCLUSIONS

The current body of literature around XR for pediatric pain is focused on acute pain with promising results of safety and effectiveness on pain intensity. The literature pertaining to chronic pain lags behind, limiting our ability to draw conclusions. The risk of bias in studies is problematic in this field, with the inherent challenge of blinding participants and researchers to the intervention. Future research should aim to measure effectiveness beyond pain intensity with a consistent approach to measuring key outcome domains and measures. Current efforts are underway to establish expert consensus on best research practices in this field.

Teens and opioids postsurgery (TOPS): protocol for a prospective observational study describing associations between sleep deficiency and opioid use following outpatient surgery in adolescents

INTRODUCTION

The opioid crisis is a significant burden on adolescent public health in the USA. Medical use of prescription opioids is a pathway via which adolescents transition to opioid misuse, opioid use disorder and overdose. More than half of all opioids prescribed to adolescents are for pain management following surgery. Yet, little is known about the critical period following surgery during which adolescents initiate opioid misuse or the modifiable mechanisms (such as sleep deficiency) contributing to this process. This prospective observational study will broaden our knowledge by examining associations between sleep deficiency and opioid use and misuse following surgery. We will also examine behavioural, psychological, family and social factors linking sleep deficiency with opioid use and misuse.

METHODS AND ANALYSIS

Adolescents (10-19 years) undergoing outpatient orthopaedic surgery, along with one parent, will be recruited from two paediatric hospitals, for a sample of 400 dyads. Adolescents will be assessed at six timepoints. Before surgery, participants will undergo comprehensive multimodal sleep assessments (sleep surveys and actigraphy). Participants will also report on previous substance use, pain intensity and psychosocial, family and social factors. Adolescents will then be closely monitored over the first 14 days following surgery using ecological momentary assessment methods to capture real-time, naturalistic, daily data on sleep, opioid use, pain and psychological factors (including mood, affect and subjective response to opioid use). Opioid use (total number of doses and duration) will be measured with an innovative electronic medication monitoring device following surgery. Follow-up assessments at 3 months, 6 months, 12 months and 24 months will track the development of opioid misuse over time. Our primary outcomes include opioid use during the immediate 14 days following surgery and the presence of opioid misuse at 24 months after surgery. Multilevel mediation models will determine associations between predictor variables and acute postsurgical opioid use. We will apply modern machine learning algorithms to develop and validate models predicting adolescent prescription opioid misuse at 24 months from surgery.

ETHICS AND DISSEMINATION

This study was approved by Advarra's Center for Institutional Review Board Intelligence (CIRBI) (Protocol 00072049), which serves as the single IRB of record for this multisite study.

Optimizing psychological treatments for pediatric chronic pain to enhance outcomes, availability, and accessibility

Although the evidence-base for psychological treatments for pediatric chronic pain (CP) is promising, the rigor and quality of existing studies remains variable and psychological treatments for pediatric CP are often inaccessible to youth that may benefit. Persistence in the rates and devastating impact of chronic pain for children and adolescents suggests a need to improve both the quality and availability of psychological treatments for pediatric CP. This brief review aims to provide an overview of the primary developmentally tailored, evidence-based, psychological treatments for pediatric CP (e.g. Cognitive Behavioral Therapy and Acceptance and Commitment Therapy). We also highlight two requisite directions for future research and program development efforts on psychological treatments for pediatric CP: 1) optimizing and tailoring treatments for real world treatment settings in partnership with end users (i.e. youth, providers) and 2) addressing barriers at multiple levels which impact both the availability and accessibility of evidence-based psychological treatments for CP.

Sex and age effects on chronic inflammatory pain development, maintenance, and resolution in Wistar rats

Millions of Americans live with chronic inflammatory pain conditions, and the prevalence of these conditions increases with age and is higher in females. Still, it is poorly understood how sex, age and peripheral gene expression affect the trajectory of chronic inflammatory pain conditions. We used the inflammatory agent, Complete Freund's Adjuvant (CFA), to systematically test sex and age effects on mechanical and thermal sensitivity in adolescent and adult male and female Wistar rats over 3 weeks (Experiment 1 [onset]) or 11 weeks (Experiment 2 [recovery]). We report that relative to male CFA rats, CFA females are mechanically hypersensitive at all time points and thermally hypersensitive at later time points (long-term during maintenance and recovery). Also, within CFA rats, more adult males (90%) achieved behavioral recovery at 11 weeks, relative to adolescent males (70%), adult females (70%) and adolescent females (50%). Behavioral recovery was most highly correlated with thermal nociception scores in most groups. Among adult males, significant positive correlations were seen between mechanical and thermal nociception scores and between scores in the CFA-injected and non-injected paws. In paw tissue from a subset of rats from experiment 2, we also report increased transient receptor potential cation channel subfamily V member 1 (TRPV1) gene expression in adult CFA but not adolescent CFA rats, and increased pro- and anti-inflammatory, and triglyceride synthesis-related gene expression in all CFA rats. Our results demonstrate apparent sex and age differences in the trajectory of chronic inflammatory pain-related behavior and gene expression in the affected paw of rats. PERSPECTIVE: This article highlights sex and age differences in the trajectory of chronic inflammatory pain and possible peripheral mechanisms driving recovery in Wistar rats. This data could be used to better understand recovery patterns in patients with this type of pain and provides a starting point for assessment of novel treatments.

Coping in youth living with chronic pain: A systematic review of qualitative evidence

Background

Chronic pain is progressively receiving attention as a universal public health priority. It is anticipated that there will be an increase in the prevalence of chronic pain in the coming years, particularly among youth. Chronic pain can be stressful and have a significant impact on young people and their family.

Aims

The aim of this systematic review was to synthesize the best available qualitative evidence on the coping experiences of youth living with chronic pain and to note whether there were any differences in their coping experiences.

Methods

A multi-database search was conducted including child development and adolescent studies. CINAHL, MEDLINE, PsycINFO, Embase, and Scopus were searched for eligible English-language articles from inception to December 2023. Out of 1625 article titles and abstracts screened for eligibility, 280 articles underwent full-text screening, with 20 ultimately meeting all inclusion criteria. We conducted a thematic analysis of data extracted from the 20 reviewed articles.

Results

We arrived at two synthesized findings. A Different Way of Being considers the experience of being a youth with chronic pain. Learning to Get By looks at the coping strategies youth use to manage their chronic pain and involved youth using self-directed strategies, as well as relying on external supports.

Conclusions

It is apparent from these synthesized findings that youths' lives have been significantly impacted by chronic pain. Findings from this study can be used to support the care and well-being of youth living with chronic pain.

Exploring Pain and Opioid Misuse Among Patients With Sickle Cell Anemia: Associations With Health Literacy and Pain Catastrophizing

PURPOSE

This study aimed to investigate pain characteristics, opioid misuse prevalence, and the relationship between healthliteracy and pain catastrophising in patients with Sickle Cell Disease (SCD).

DESIGN

This was a cross-sectional study.

METHODS

Data were collected from patients with SCD in Oman. Validated tools were used to assess pain (Brief Pain Inventory), healthliteracy (HLS-Q12), opioid misuse (Current Opioid Misuse Measure [COMM]), and pain catastrophising (Pain Catastrophising Scale).

RESULTS

The study included 169 patients with SCD, with an average age of 34.4 (SD = 12.9) years, of whom 51.5% werefemale. A total of 79.3% of the participants reported experiencing pain, with an average total pain score of 3.8 (SD = 2.6).Additionally, 74% of the patients were identified as being at risk of opioid misuse. The risk of opioid misuse was positivelyassociated with pain catastrophising (r = 0.302, p < 0.001) and negatively associated with health literacy (r = -0.220, p = 0.005). Pain severity and interference are also linked to the risk of opioid misuse. Sociodemographic factors, such as age, sex, and education, showed no significant association with the risk of opioid misuse.

CONCLUSIONS

Patients with SCD face high rates of chronic pain and considerable risk of opioid misuse. Psychological factors, particularly pain catastrophising and lower healthliteracy, were strongly associated with misuse risk, while sociodemographic factors had less impact.

CLINICAL IMPLICATIONS

These findings highlight the need for targeted interventions addressing psychological support and health literacy to reduce opioidmisuse in SCD patients. Healthcare providers should integrate pain management strategies with educational programs to enhancehealth literacy and mitigate the psychological burden of pain.

The Impact of a Brief Educational Seminar on Pediatric Pain-focused Cognitive-Behavioral Therapy for School Providers

OBJECTIVES

Pediatric chronic pain is common and can be detrimental to children's social, emotional, and school functioning. Nonpharmacological approaches to chronic pain, like cognitive- behavioral therapy (CBT), can be effective. Schools could provide children with chronic pain access to these interventions. However, school professionals (ie, nurses and mental health providers) are seldom trained in CBT, creating a barrier to accessing such help. A seminar was created to introduce CBT strategies for chronic pediatric pain to school professionals. Feasibility, acceptability, and self-reported knowledge gained from the seminar were examined.

MATERIALS AND METHODS

Two introductory seminars (~2.5 h each) were held separately for the Michigan Association of School Nurses and the health department of Northwest Michigan (n = 71 total). The seminar provided an understanding of pain and pain-focused CBT strategies (eg, activity pacing, positive self-statements, and psychoeducation). Fifty-two school nurses, 16 mental health professionals, and 3 participants (unidentified title) rated program acceptability and self-reported knowledge of CBT before and after training (1 = strongly disagree, 5 = strongly agree).

RESULTS

Of the respondents, 89.6% agreed the training was helpful, and 87.5% were interested in additional training. For all questions relating to knowledge of CBT, a mixed-model interaction showed a meaningful, increase of at least 1 point (on a 5-point Likert Scale), F(2, 69.83) = 3.93, P = 0.024.

CONCLUSION

This study underscores the feasibility and acceptability of training school health providers in CBT for pediatric chronic pain. This project also established key partnerships in Michigan to expand future work in this realm with more comprehensive training and assessment of outcomes.

Sex differences in comorbid pain and opioid use disorder: A scoping review

Opioid use disorder (OUD) and chronic pain are commonly co-occurring disorders which can exacerbate each other. Sex/gender differences have been shown in aspects of the clinical course and biological underpinnings of both OUD and chronic pain. The purpose of this scoping review is to summarize literature which has addressed sex/gender differences in relation to the confluence of OUD and chronic pain. This review focused on peer-reviewed journal articles with human subjects and addressing (a) opioid misuse, chronic opioid use or opioid use disorder (OUD), (b) chronic or persistent pain and (c) sex/gender differences in relation to OUD and/or chronic pain. Of the 146 papers identified by the search strategy, 30 met the criteria for inclusion. Charting focused on a priori themes of chronic pain, opioid misuse/OUD and sex/gender in sample, predictor and outcome variables, and key study findings. The majority of research identified was cross-sectional in nature, and sex/gender differences and treatment effects were largely included as post-hoc analyses. Together, the results of this early work align with higher prevalence for OUD in men/males and chronic pain in women/females, while adding critical information with respect to potential sex/gender differences in the development and treatment of their co-occurrence across a range of biological and psychosocial factors. Findings underline the importance of considering sex and gender in the intersection of the development and treatment of OUD and chronic pain.

Pain-Associated Diagnoses in Childhood Before the Diagnosis of Attention-Deficit/Hyperactivity Disorder: A Population-Based Study

Background: Pediatric pain significantly affects children's lives, leading to school absenteeism, impaired social interactions, and psychological distress. The perception of sensory signals as pain is influenced by the brain's noradrenergic system, and recent evidence suggests that chronic pain may impact cognitive functioning and emotional regulation. Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with alterations in the dopaminergic/noradrenergic systems, which could affect pain perception. Pain-associated conditions and frequent analgesic use in childhood may be linked to ADHD development and could serve as early indicators, yet data on this potential association remain limited. Study Aim: This population-based case-control study in Israel aimed to assess the prevalence of pain-related diagnoses prior to ADHD diagnosis in children aged 5 to 18. The study included children registered with Leumit Health Services (LHS) between 1 January 2006, and 30 June 2021. Children diagnosed with ADHD were compared to matched controls, selected based on age, gender, socioeconomic status, and other sociodemographic factors, who were never diagnosed with ADHD during the study period. Results: Children with ADHD (N = 18,756) and controls (N = 37,512) were precisely matched for sociodemographic characteristics. Individuals with ADHD exhibited significantly higher frequencies of diverse pain conditions, including those associated with illness [headache, earaches, and throat pain (odds ratios [OR] = 1.156 [95%CI 1.085, 1.232], 1.295 [95%CI 1.217, 1.377], and 1.080 [95%CI 1.019, 1.145], respectively; p < 0.01)] and injury [sprains and strains (OR = 1.233 [95% CI 1.104,1.376)]. Analgesics were more frequently purchased by individuals with ADHD, particularly paracetamol (OR = 1.194 [95%CI 1.152, 1.237], p < 0.001) and ibuprofen (OR = 1.366 [95%CI 1.318, 1.416], p = 0.001). Conclusions: This study highlights a potential connection between ADHD and pediatric pain. The elevated rates of pain diagnoses and analgesic usage among children with ADHD underscore the need for further research.

Tribal Identity, Pain Interference, and Substance Use Among American Indian and Alaska Native Adolescents

Importance

Substance use is high among American Indian/Alaska Native adolescents. Pain interference is a risk factor for substance use, and identifying potential protective factors, such as Tribal identity, is important to help inform culturally grounded substance use prevention strategies.

Objective

To examine the protective potential of Tribal identity as a moderator in the association between pain interference and substance use in American Indian/Alaska Native adolescents.

Design, Setting, and Participants

This cross-sectional study of 10th-grade students self-identifying as American Indian/Alaska Native was conducted among students enrolled at 20 high schools on or near the Cherokee Nation Reservation. Data for this study were collected from the baseline assessments of a cluster randomized trial to prevent substance use among adolescents living on or near the Cherokee Nation Reservation. Inclusion criteria for high schools' participation included being located within counties that partially or fully fall within the Cherokee Nation reservation, a town population of 3000 individuals or fewer, and class sizes between 30 and 100 students. Exclusion criteria included high schools within metropolitan and micropolitan cores (per the US Census Bureau's Rural-Urban Commuting Area codes) and the existence of an established community drug prevention coalition. Student surveys were conducted from September 2021 to May 2024.

Exposure

Pain interference in the 7 days prior to baseline assessment.

Main Outcomes and Measures

The primary outcomes were past 30-day alcohol use, marijuana use, and prescription opioid misuse. Generalized estimating equations Poisson models were used, with an exchangeable correlation structure clustered on the school level using baseline data from a cluster randomized trial to prevent alcohol and substance use among adolescents. For each substance, a separate multivariable model was fit, which included pain interference, Tribal identity, an interaction term between pain interference and Tribal identity, age, gender, food insecurity, anxiety symptoms, and depressive symptoms.

Results

Among 514 self-identified American Indian/Alaska Native students at 20 high schools on or near the Cherokee Nation Reservation, mean (SD) participant age was 15.59 (0.62) years, and 252 participants (49.0%) self-identified as female. Pain interference was associated with alcohol use and prescription opioid misuse in American Indian/Alaska Native adolescents, controlling for age, gender, food insecurity, anxiety symptoms, and depressive symptoms. Tribal identity significantly moderated the association between pain interference and alcohol use (coefficient, -0.13; 95% CI, -0.23 to -0.02).

Conclusions and Relevance

When Tribal identity was high, the adverse association of pain interference with alcohol use was significantly attenuated. This demonstrates a protective role of Tribal identity on alcohol use, which can inform future substance use prevention efforts among American Indian/Alaska Native adolescents.

Helping Educators Learn Pediatric Pain Assessment and Intervention Needs Program (HELP PAIN): Program Development with Community Partners

BACKGROUND/OBJECTIVES

This paper details the development of the Helping Educators Learn Pediatric Pain Assessment and Intervention Needs (HELP PAIN) program.

METHODS

HELP PAIN is an 8 h live training program for school providers (e.g., school nurses and social workers) to use evidence-based nonpharmacologic pediatric pain management tools. The program's scope reflected the reach of the participating intermediary community organizations, resulting in focused training in rural northwest Michigan due to the Health Department of Northwest Michigan's service in that region and statewide reach due to the broad representation of members from the Michigan Association of School Nurses.

RESULTS

We describe the development of the HELP PAIN program, drawing on evidence-based nonpharmacologic (e.g., cognitive behavioral and mindfulness meditation) strategies for pediatric pain management.

CONCLUSIONS

In partnership with the key community organizations and community partners, we developed, interactively refined, and delivered this training program.

Patients with refractory musculoskeletal pain syndromes undergoing a multimodal assessment and therapy programme: a cross-sectional study

BACKGROUND

Chronic musculoskeletal pain syndromes, including fibromyalgia, are heterogeneous entities with a major socioeconomic burden. Multimodal treatment programmes have shown greater efficacy than conventional approaches for these patients, at least in the short term. A profound understanding of chronic musculoskeletal pain syndrome patients treated in multimodal treatment programmes is important for their development and to provide insight into these conditions.

AIM

To provide a comprehensive and objective description of medical, psychosocial and sleep characteristics of the treatment-refractory chronic musculoskeletal pain syndrome patients treated at the multimodal treatment programmes provided by our tertiary service in Switzerland.

METHODS

This was a cross-sectional analysis of 202 refractory chronic musculoskeletal pain syndrome patients with or without a concomitant autoimmune disorder hospitalised between 2018 and 2022 in a 12-day Swiss multimodal treatment programme. They underwent a comprehensive self-assessment with eight different questionnaires and assessments by a psychiatrist, rheumatologist, pain specialist, occupational therapist and physiotherapist. Sleep assessment was performed via actigraphy. Clinical and demographic variables were selected by consensus of three experienced rheumatologists and chronic pain specialists. The Fibromyalgia Rapid Screening Test (FiRST), American College of Rheumatology (ACR)-2010 criteria (ACR2010) and Toronto Alexithymia Scale-20 (TAS-20) were also applied.

RESULTS

The mean age of the patients was 47 years (SD = 10), 73% were female, and 30% were obese. Half (50%) were not from Switzerland, and 12% came from conflict zones. Almost half (40%) lived alone. Back pain was the principal site (90%). Of the patients, 78% fulfilled the ACR2010 criteria for fibromyalgia, and 17% were diagnosed with an underlying immune-mediated disorder, mostly spondylarthritis. Pain since childhood occurred in 45% of the patients, and 68% had pain since adolescence. Disability financial aid had been pursued by 69%, and 46% were still awaiting a response. Psychiatric comorbidities were highly prevalent (73%), of which 56% consisted of depression. Of all patients, 15% were diagnosed with enduring personality changes after a catastrophic experience (EPCACE), and 10% had post-traumatic stress disorder. Alexithymia affected 34% of patients. Objective sleep disorder was observed in 78% of patients, and 41% were under opioid therapy.

CONCLUSION

This analysis reveals the complex psychosomatic and socioeconomic patterns of the patients treated in Switzerland with refractory chronic musculoskeletal pain syndromes, often originating in childhood and adolescence. Obesity, immigration, social isolation, psychiatric comorbidities, sleep deprivation and opiate use, among others, stood out as target characteristics for further research.

Examining changes in pain interference via pandemic-induced isolation among patients receiving medication for opioid use disorder: a secondary data analysis

BACKGROUND

Early in the pandemic, the United States population experienced a sharp rise in the prevalence rates of opioid use, social isolation, and pain interference. Given the high rates of pain reported by patients on medication for opioid use disorder (MOUD), the pandemic presented a unique opportunity to disentangle the relationship between opioid use, pain, and social isolation in this high-risk population. We tested the hypothesis that pandemic-induced isolation would partially mediate change in pain interference levels experienced by patients on MOUD, even when controlling for baseline opioid use. Such work can inform the development of targeted interventions for a vulnerable, underserved population.

METHODS

Analyses used data from a cluster randomized trial (N = 188) of patients on MOUD across eight opioid treatment programs. As part of the parent trial, participants provided pre-pandemic data on pain interference, opioid use, and socio-demographic variables. Research staff re-contacted participants between May and June 2020 and 133 participants (71% response rate) consented to complete a supplemental survey that assessed pandemic-induced isolation. Participants then completed a follow-up interview during the pandemic that again assessed pain interference and opioid use. A path model assessed whether pre-pandemic pain interference had an indirect effect on pain interference during the pandemic via pandemic-induced isolation.

RESULTS

Consistent with hypotheses, we found evidence that pandemic-induced isolation partially mediated change in pain interference levels among MOUD patients during the pandemic. Higher levels of pre-pandemic pain interference and opioid use were both significantly associated with higher levels of pandemic-induced isolation. In addition, pre-pandemic pain interference was significantly related to levels of pain interference during the pandemic, and these pain levels were partially explained by the level of pandemic-induced isolation reported.

CONCLUSIONS

Patients on MOUD with higher use of opioids and higher rates of pain pre-pandemic were more likely to report feeling isolated during COVID-related social distancing and this, in turn, partially explained changes in levels of pain interference. These results highlight social isolation as a key risk factor for patients on MOUD and suggest that interventions promoting social connection could be associated with reduced pain interference, which in turn could improve patient quality of life.

Peer Victimization, Posttraumatic Stress Symptoms, and Chronic Pain: A Longitudinal Examination

Chronic pain and posttraumatic stress disorder symptoms (PTSS) co-occur at high rates in youth and are linked to worse pain outcomes and quality of life. While peer victimization has been posited as a mechanism underlying the PTSS-pain relationship in youth, empirical evidence suggests that it may exacerbate both PTSS and pain. The present study aimed to longitudinally examine PTSS as a mediator in the relationship between peer victimization at baseline and pain-related outcomes at 3 months in youth with chronic pain. Participants included 182 youth aged 10 to 18 years recruited from a tertiary-level children's hospital in Western Canada. At baseline, participants completed measures to assess pain (intensity and interference), peer victimization (relational and overt), and PTSS. The pain was reassessed at a 3-month follow-up. Primary hypotheses were tested utilizing a series of mediation analyses with PTSS as a proposed mediator in the associations between peer victimization and pain outcomes. Youth PTSS mediated the relationship between higher baseline relational victimization and higher 3-month pain interference while controlling for baseline pain interference. Three-month pain intensity was not correlated with peer victimization; thus, pain intensity was not included in the analyses. These findings reveal that PTSS may be an underlying factor in the co-occurrence of peer victimization and chronic pain in youth. Further research is needed to better understand the role of peer victimization in the maintenance of chronic pain to ensure appropriate, effective, and timely interventions that address the social and mental health issues impacting the lives of these youth as well as their pain. PERSPECTIVE: PTSS may be an underlying factor in the co-occurrence between peer victimization and chronic pain in youth, highlighting the need to assess for both peer relationship problems and PTSS in youth with chronic pain.

Adverse Childhood Experiences Moderate the Relationship Between Pain and Later Suicidality Severity Among Youth: A Longitudinal High-Risk Cohort Study

Pain in adolescence can lead to the development of serious mental health issues, including suicidality. This risk may be strengthened among youth exposed to more adverse childhood experiences (ACEs; abuse, neglect, household challenges). This longitudinal study examined the role of ACEs in the relationship between pain and later suicidality onset and severity among a cohort of adolescents at risk for developing mental health problems. Participants were 139 healthy youth (Mage = 13.74 years, standard deviation = 1.56, 64% female) between the ages of 11 to 17 years, recruited based on parental history of depression or anxiety. Youth completed validated measures of internalizing symptoms, ACEs, and pain characteristics at baseline and follow-up diagnostic interviews 9 and/or 18 months later to assess for onset and severity of suicidality. After controlling for demographics, baseline internalizing symptoms, and ACEs, worse pain interference and increased ACEs at baseline predicted increased suicidality severity at follow-up. Moderation analyses revealed that there was a significant interaction between ACEs and pain interference and pain intensity. Increased pain interference (b = 7.65, P < .0001) or intensity (b = 6.96, P = .0003) was only associated with increased suicidality severity at follow-up in youth with high levels of ACEs. This study demonstrates that ACEs strengthen the relationship between pain and later suicidality severity among youth at risk of developing mental health problems. Findings underscore the critical need to adopt a trauma-informed lens to pediatric pain prevention and treatment (eg, screening for ACEs) and for the pain to be on the child's mental health agenda. PERSPECTIVE: This article provides evidence that, while pain is a risk factor for future increased suicidality severity, it is a particularly strong risk factor in youth who experienced increased childhood adversity. These results may help identify youth at greatest risk for suicidality.

Early childhood risk factors for later onset of pediatric chronic pain: a multi-method longitudinal study

BACKGROUND

Pediatric chronic pain (i.e., pain lasting ≥ 3 months) is prevalent, disabling, and costly. It spikes in adolescence, interrupts psychosocial development and functioning, and often co-occurs with mental health problems. Chronic pain often begins spontaneously without prior injuries and/or other disorders. Prospective longitudinal cohort studies following children from early childhood, prior to chronic pain onset, are needed to examine contributing factors, such as early pain experiences and mental health. Using data from a longitudinal community pregnancy cohort (All Our Families; AOF), the present study examined the associations between early developmental risk factors, including early childhood pain experiences and mental health symptoms, and the onset of pediatric chronic pain at ages 8 and 11 years.

METHODS

Available longitudinal AOF data from child age 4 months, as well as 1, 2, 3, 5, 8, and 11 years, were used. Mothers reported their child's pain experiences (e.g., hospitalizations, vaccinations, gut problems) at each timepoint from 4 months to 8 years, child chronic pain at age 8, and child mental health symptoms at ages 5 and 8 years. Children reported their chronic pain frequency and interference at age 11. Adaptive least absolute shrinkage and selection operator (LASSO) regressions were used to select predictor variables. Complete case analyses were complemented by multiple imputation using chained equation (MICE) models.

RESULTS

Gut problems, emergency room visits, frequent pain complaints, and headaches at age 5 or earlier, as well as female sex, were associated with increased risk of maternal reported child chronic pain at age 8. Maternal reported chronic pain at age 8 was associated with higher levels of child-reported pain frequency and pain interferences at age 11. Boys self-reported lower levels of pain interference at age 11.

CONCLUSIONS

Some, but not all, painful experiences (e.g., gut problems, ER visits, pain complaints) in early life contribute to pediatric chronic pain onset and should be considered for screening and early intervention.

Brain Function and Pain Interference After Pediatric Intensive Interdisciplinary Pain Treatment

OBJECTIVES

Intensive interdisciplinary pain treatments (IIPTs) are programs that aim to improve functioning in youth with severe chronic pain. Little is known about how the brain changes after IIPT; however, decreased brain responses to emotional stimuli have been identified previously in pediatric chronic pain relative to healthy controls. We examined whether IIPT increased brain responses to emotional stimuli, and whether this change was associated with a reduction in pain interference.

PATIENTS AND METHODS

Twenty youths with chronic pain aged 14 to 18 years were scanned using functional magnetic resonance imaging, pre and post-IIPT. During the functional magnetic resonance imaging, patients were presented with emotional stimuli (ie, faces expressing happiness/fear), neutral expressions, and control (ie, scrambled) images. Patients completed a measure of pain interference pre and post-IIPT. Paired t tests were used to examine differences in brain activation in response to emotional versus neutral stimuli, pre to post-IIPT. Data from significant brain clusters were entered into linear mixed models to examine the relationships between brain activation and impairment pre and post-IIPT.

RESULTS

Patients demonstrated a decrease in middle frontal gyrus (MFG) activation in response to emotional stimuli (happy + fear) relative to scrambled images, between pre and post-IIPT ( P < 0.05). Lower MFG activation was associated with lower pain interference, pre and post-IIPT ( P < 0.05).

CONCLUSION

Contrary to our hypothesis, IIPT was associated with a reduction in MFG activation to emotional stimuli, and this change was associated with reduced pain interference. The MFG is a highly interconnected brain area involved in both pain chronification and antinociception. With further validation of these results, the MFG may represent an important biomarker for evaluating patient treatment response and target for future pain interventions.

Ecological momentary assessment of sleep, pain, and opioid use among adolescents following surgery

Background

Opioids are effective for acute pain management following surgery among adolescents, yet are associated with significant negative consequences, including respiratory depression and opioid misuse. Sleep deficiency is common following surgery and extant research indicates strong cross-sectional associations between sleep deficiency and increased problematic opioid use.

Objective

This study examined longitudinal associations between postsurgical sleep deficiency and opioid use among adolescents undergoing outpatient surgery. We also examined daily pain and mood as mechanisms linking previous night's sleep deficiency and next day prescription opioid use.

Methods

This prospective, observational study enrolled 106 adolescents (11-19 years) who underwent orthopedic outpatient surgery and collected pre-surgery and longitudinal measurements. Participants were 52% female, African-American (7%), American Indian/Alaska Native (7%), Hispanic (9%), Native Hawaiian or Other Pacific Islander (4%), or white, non-Hispanic (66%). Using ecological momentary assessment methods, participants reported sleep, pain, and mood in real time over the first 14 days following surgery. Postsurgical opioid use was measured using an electronic medication cap monitoring device, eCAPTM. Associations between variables were measured using multilevel structural equation modeling.

Results

Using multi-level mediation models, pain, but not mood-mediated associations between postsurgical sleep deficiency (sleep quality, total sleep time, sleep onset latency, and wake after sleep onset) and opioid use, at both the within-person and between-person levels. Results highlight that greater previous night's sleep deficiency (both generally and greater than a person's mean level) was associated with higher next day pain (both generally and greater than a person's mean level), which, in turn, was associated with higher opioid use. Furthermore, between-person total effect models provide support for sleep deficiency predicting higher opioid use.

Conclusions

Our findings should be considered preliminary yet underscore the need for a comprehensive and personalized approach to postsurgical pain management and opioid use, potentially implementing interventions targeting sleep quality and quantity to reduce pain and opioid use.

Childhood trauma and the use of opioids and other prescription analgesics in adolescence and young adulthood: The HUNT Study

ABSTRACT

Opioid and nonopioid analgesics are commonly prescribed to young people to alleviate pain. Even short-term prescriptions increase the risk of persistent use and future misuse of potent analgesics, such as opioids. Childhood trauma exposure has been found to be related to pain conditions and to using more prescription analgesics. This large, prospective cohort study aimed to investigate the association of a broad range of childhood trauma exposures with prescription rates for opioid and nonopioid analgesics in adolescence and young adulthood. Self-reported data on childhood trauma exposures from adolescents (aged 13-19 years) who participated in the Young-HUNT3 Study (2006-2008, n = 8199) were linked to data from the Norwegian Prescription Database (NorPD, 2004-2021). We found that exposure to childhood trauma was consistently associated with higher prescription rates for opioids throughout adolescence and young adulthood. The highest incidence rate ratio (IRR) in adolescence was observed for sexual abuse (IRR 1.63, confidence interval [CI] 1.19-2.23). In young adulthood, the highest IRR was observed for physical violence (2.66, CI 2.27-3.12). The same overall pattern was observed for nonopioid analgesics. The more frequent prescriptions of opioid and nonopioid analgesics to participants exposed to childhood trauma suggests a higher symptom load of pain causing them to seek professional help with pain relief. Receiving potent analgesics is not without risk, and the likelihood of misuse may be elevated among trauma-exposed individuals. A trauma-informed approach to pain could be vital for guiding clinicians to the most effective and least harmful treatment for each patient.

Trauma exposure across the lifespan among individuals engaged in treatment with medication for opioid use disorder: differences by gender, PTSD status, and chronic pain

BACKGROUND

There is little study of lifetime trauma exposure among individuals engaged in medication treatment for opioid use disorder (MOUD). A multisite study provided the opportunity to examine the prevalence of lifetime trauma and differences by gender, PTSD status, and chronic pain.

METHODS

A cross-sectional study examined baseline data from participants (N = 303) enrolled in a randomized controlled trial of a mind-body intervention as an adjunct to MOUD. All participants were stabilized on MOUD. Measures included the Trauma Life Events Questionnaire (TLEQ), the Brief Pain Inventory (BPI), and the Posttraumatic Stress Disorder Checklist (PCL-5). Analyses involved descriptive statistics, independent sample t-tests, and linear and logistic regression.

RESULTS

Participants were self-identified as women (n = 157), men (n = 144), and non-binary (n = 2). Fifty-seven percent (n = 172) self-reported chronic pain, and 41% (n = 124) scored above the screening cut-off for PTSD. Women reported significantly more intimate partner violence (85%) vs 73%) and adult sexual assault (57% vs 13%), while men reported more physical assault (81% vs 61%) and witnessing trauma (66% vs 48%). Men and women experienced substantial childhood physical abuse, witnessed intimate partner violence as children, and reported an equivalent exposure to accidents as adults. The number of traumatic events predicted PTSD symptom severity and PTSD diagnostic status. Participants with chronic pain, compared to those without chronic pain, had significantly more traumatic events in childhood (85% vs 75%).

CONCLUSION

The study found a high prevalence of lifetime trauma among people in MOUD. Results highlight the need for comprehensive assessment and mental health services to address trauma among those in MOUD treatment.

Opioids and Youth Athletes

CONTEXT

The ongoing opioid epidemic and associated adverse effects impart a large burden on our current healthcare system. The annual economic and noneconomic cost of opioid use disorder and fatal opioid overdose is currently estimated at $1 trillion.

OBJECTIVE

This review presents the prevalence, frequency of use, need, and effectiveness of opioid analgesia in the youth and adolescent athlete population. It identifies current indications for opioid versus nonopioid analgesic use in the setting of acute orthopaedic injuries, postoperative management, concussion, and chronic pain. Current knowledge of youth athlete opioid use, risks related to use, misuse, diversion, and addiction are reviewed.

DATA SOURCES

A PubMed, Medline, and Cochrane Library search was conducted in February 2023 to review opioid pain management strategies in the pediatric athlete population from 2000 to present.

STUDY SELECTION

Searches were restricted to English language articles and human subjects. Initial reviews of titles and abstracts were performed by all authors and relevant full-text articles were selected. Priority was given to systematic and narrative reviews, meta-analyses, and prospective studies.

STUDY DESIGN

Narrative review.

LEVEL OF EVIDENCE

Level 3.

DATA EXTRACTION

First author name, publication year, study design, study country, subject demographics, and data on the frequency, type, and duration of analgesic treatments for musculoskeletal injuries, postsurgical care, chronic pain disorders, and concussion were extracted.

RESULTS

Pediatric athletes comprise a high-risk population seeking analgesic relief for injury-related pain. Participation in high school sports is associated with increased risk of opioid use. An average of 28% to 46% of high school athletes have used opioids in their lifetime. Participation in ≥1 high school sport puts adolescents at 30% greater odds of future opioid misuse.

CONCLUSION

The use of opioids in the pediatric athlete population is common and associated with both short- and long-term risks of misuse and addiction.

Non-Pharmacologic Intensive Interdisciplinary Pain Treatment in Pediatrics: Impact on Symptoms, Daily Functioning, and the Family Unit

Objectives: To assess non-pharmacologic treatment outcomes pertaining to health-related quality of life (HRQoL) in youth with chronic idiopathic pain and their families. Methods: We conducted a retrospective cohort study of 115 youth with chronic idiopathic pain enrolled in a non-pharmacologic, hospital-based intensive interdisciplinary pain treatment (IIPT) program. HRQoL measures for the patient (Pediatric Quality of Life Inventory [PedsQL] short form) and family unit (PedsQL Family Impact) were collected on admission and discharge as part of routine clinical care. Changes in PedsQL scores were calculated using the Wilcoxon signed-rank test. Multivariable linear regression was used to explore factors associated with patient-level HRQoL. Results: Both individuals and the family unit reported that their HRQoL improved in all domains by program completion. Improvements in pain and allodynia were present for program participants at the time of completion as well as at the 3-month follow-up, suggesting durability of these effects. Conclusions: A non-pharmacologic IIPT program is a compelling treatment for pediatric and adolescent chronic idiopathic pain, for both patients and the family unit. Patients participating in this program had positive treatment outcomes with significantly improved subjective and objective measures of physical, emotional, social, and cognitive function.

Comorbidity of Lifetime History of Abuse and Trauma With Opioid Use Disorder: Implications for Nursing Assessment and Care

BACKGROUND

Opioid use disorder (OUD) is a public health crisis and is challenging to treat. Previous research has shown correlations between OUD, abuse/trauma, and chronic pain.

AIMS

The purpose of this study was to investigate history of lifetime sexual, physical, and/or emotional abuse among participants in a medication-assisted treatment (MAT) program for OUD, and to investigate associations between abuse history and chronic pain.

METHODS

This is a secondary analysis of intake data from a 2-year, nonexperimental cohort treatment program of patients with OUD in rural Colorado. De-identified data were provided by 476 adult MAT patients using the Adult Addiction Severity Index (ASI-6). The ASI-6 includes three yes/no questions about history of abuse (emotional, physical, and sexual), with separate scoring for "past 30 days" and "lifetime" abuse.

RESULTS

Lifetime history among MAT program for OUD patients was 23% for sexual abuse, 43% for physical abuse, and 58% for emotional abuse. History of physical abuse was significantly associated with having a chronic pain diagnosis, χ2 = 4.49, p = .03, and also with higher reported pain levels, t(460) = 2.71, p = .007.

CONCLUSION

Lifetime history of physical abuse was associated with OUD and chronic pain, yet standard pain assessments do not assess these factors. In health care settings, the implementation of standardized trauma-informed screening tools, prompt recognition of abuse/trauma history, and adjunct psychological interventions may reduce stigma, reduce opioid use escalation, and help patients overcome OUD.

Traumatic Brain Injury and Opioids: Twin Plagues of the Twenty-First Century

Traumatic brain injury (TBI) and opioid use disorder (OUD) comprise twin plagues causing considerable morbidity and mortality worldwide. As interactions between TBI and OUD are to our knowledge uncharted, we review the possible mechanisms by which TBI may stimulate the development of OUD and discuss the interaction or crosstalk between these two processes. Central nervous system damage due to TBI appears to drive adverse effects of subsequent OUD and opioid use/misuse affecting several molecular pathways. Pain, a neurological consequence of TBI, is a risk factor that increases the likelihood of opioid use/misuse after TBI. Other comorbidities including depression, anxiety, posttraumatic stress disorder, and sleep disturbances are also associated with deleterious outcomes. We examine the hypothesis that a TBI "first hit" induces a neuroinflammatory process involving microglial priming, which, on a second hit related to opioid exposure, exacerbates neuroinflammation, modifies synaptic plasticity, and spreads tau aggregates to promote neurodegeneration. As TBI also impairs myelin repair by oligodendrocytes, it may reduce or degrade white matter integrity in the reward circuit resulting in behavioral changes. Along with approaches focused on specific patient symptoms, understanding the CNS effects following TBI offers a promise of improved management for individuals with OUD.

Trauma Exposure Across the Lifespan among Individuals Engaged in Treatment with Medication for Opioid Use Disorder: Differences by Gender, PTSD Status, and Chronic Pain

Fifty-seven percent (n = 172) self-reported chronic pain, and 41% (n = 124) scored above the screening cut-off for PTSD. Women reported significantly more intimate partner violence (85%) vs 73%) and adult sexual assault (57% vs 13%), while men reported more physical assault (81% vs 61%) and witnessing trauma (66% vs 48%). Men and women experienced substantial childhood physical abuse, witnessed intimate partner violence as children, and reported an equivalent exposure to accidents as adults. The number of traumatic events predicted PTSD symptom severity and PTSD diagnostic status. Participants with chronic pain, compared to those without chronic pain, had significantly more traumatic events in childhood (85% vs 75%).

Conclusions

The study found a high prevalence of lifetime trauma among people in MOUD. Results highlight the need for comprehensive assessment and mental health services to address trauma among those in MOUD treatment.

Prevalence of chronic pain or analgesic use in children and young people and its long-term impact on substance misuse, mental illness, and prescription opioid use: a retrospective longitudinal cohort study

Background

Epidemiological studies suggest chronic and recurrent pain affects around a quarter of children, while 8% report intense and frequent pain. The long-term implications of chronic pain in childhood are uncertain. Using electronic health records (EHRs) we used both disease codes and medicines prescription records to investigate the scale of chronic pain and long-term analgesic use in children and young people (CYP), and if chronic pain and/or use of analgesic medicines at an early age is associated with substance misuse, use of prescription opioids, and poor mental health in adulthood.

Methods

We conducted a cohort study using data from IQVIA Medical Research Data UK. We identified individuals aged 2-24 with exposure to either a diagnostic code indicating chronic pain (diagnosis-exposed), repeat prescription for medicines commonly used to treat pain (prescription-exposed), or both. Follow-up began at 25, and the unexposed population acted as comparators. We calculated hazard ratios (HR) for mental health and substance misuse outcomes, and rate ratios (RR) for opioid prescriptions in adulthood. Additionally, we investigated which diagnoses, if any, were over-represented in the prescription-exposed subgroup.

Findings

The cohort constituted 853,625 individuals; 146,431 had one or more of the exposures of interest (diagnosis-exposed = 115,101, prescription-exposed = 20,298, both-exposed = 11,032), leaving 707,194 as comparators. Median age at index exposure was 18.7 years (IQR 14.7-22.3). On average during follow-up, the pooled exposed group had, respectively, a 31% and 17% higher risk of adverse mental health and substance misuse outcomes (adjusted HR [95% CI] of 1.31 [1.29-1.32] and 1.17 [1.11-1.24]). Exposed individuals also received prescription opioids at double the rate of unexposed individuals on average during follow-up (adjusted RR 2.01 [95% CI 1.95-2.10]). Outcomes varied between exposure subgroups, with prescription- and both-exposure tending to have worse outcomes. Unlike these two subgroups, in the diagnosis-exposed subgroup we did not detect a greater risk of substance misuse.

Interpretation

Chronic pain in CYP is associated with increased prescription opioid use and adverse mental health outcomes in adulthood, as is repeat prescription for analgesic medicines, but only the latter is also associated with substance misuse in adulthood. It is essential to avoid the harms of under-treating pain in CYP while giving due consideration to the risks posed by analgesic medicines. Early recognition of chronic pain in CYP and utilising non-pharmacological management options may help minimise overprescribing, and long-term reliance on dependence-forming-drugs.

Risk Factors for the Development of Multisite Pain in Children

OBJECTIVE

Chronic pain has economic costs on par with cardiovascular disease, diabetes, and cancer. Despite this impact on the health care system and increasing awareness of the relationship between pain and mortality, efforts to identify simple symptom-based risk factors for the development of pain, particularly in children, have fallen short. This is critically important as pain that manifests during childhood often persists into adulthood. To date, no longitudinal studies have examined symptoms in pain-free children that presage a new, multisite manifestation of pain in the future. We hypothesized that female sex, sleep problems, and heightened somatic symptoms complaints at baseline would be associated with the risk of developing new multisite pain 1 year later.

METHODS

Symptom assessments were completed by parents of youth (ages 9 to 10) enrolled in the Adolescent Brain Cognitive Development study. Multivariate logistic regression models focused on children who developed multisite pain 1 year later (n=331) and children who remained pain free (n=3335).

RESULTS

Female sex (odds ratio [OR]=1.35; 95% CI, 1.07, 1.71; P =0.01), elevated nonpainful somatic symptoms (OR=1.17; 95% CI, 1.06, 1.29; P <0.01), total sleep problems (OR=1.20; 95% CI, 1.07, 1.34; P <0.01), and attentional issues (OR=1.22; 95% CI, 1.10, 1.35; P <0.001) at baseline were associated with new multisite pain 1 year later. Baseline negative affect was not associated with new multisite pain.

DISCUSSION

Identifying symptom-based risk factors for multisite pain in children is critical for early prevention. Somatic awareness, sleep and attention problems represent actionable targets for early detection, treatment, and possible prevention of multisite pain in youth.

Pain, mental health and healthcare utilization: Impact of the COVID-19 pandemic on youth with chronic pain, parents and siblings

BACKGROUND

Paediatric chronic pain was a public health emergency before the novel coronavirus (COVID-19) pandemic, and this problem is predicted to escalate. Pain tends to occur intergenerationally in families, and youth with chronic pain and their parents have high rates of mental health issues, which can further exacerbate pain. Siblings of youth with chronic pain have been largely overlooked in research, as well as the impact of the pandemic on posttraumatic stress disorder (PTSD) symptoms and healthcare utilization.

METHODS

This cross-sectional study examined pain, mental health and healthcare utilization in three groups: youth with chronic pain (n = 357), parents of youth with chronic pain (n = 233) and siblings of youth with chronic pain (n = 156) during the COVID-19 pandemic in Canada.

RESULTS

More so than with pain symptoms, the results revealed high levels of mental health symptoms (i.e. anxiety, depressive, and PTSD), particularly in individuals more personally impacted by the pandemic. The largest effect was seen on PTSD symptoms for all groups. For parents with chronic pain, greater personal COVID-19 impact was related to worse pain interference. Reported rates of healthcare utilization were strikingly high, with youth with chronic pain, parents (reporting on behalf of their children with chronic pain), and siblings of youth with chronic pain reporting that most consultations were due to pain.

CONCLUSIONS

Longitudinal research assessing these outcomes across continued waves of the pandemic is needed to ensure timely, tailored and equitable access to pain and mental health assessment and treatment.

SIGNIFICANCE

This study examined pain, mental health, substance use and healthcare utilization in youth with chronic pain, siblings and parents during the COVID-19 pandemic. Greater personal impact of the pandemic was not largely associated with poorer pain outcomes; however, it was associated with mental health, with the largest effect on PTSD symptoms. The high rates and significant association of COVID-19 impact with PTSD symptoms underscore the importance of including PTSD assessment as part of routine screening practices in pain clinics.

Paternal morphine exposure in rats reduces social play in adolescent male progeny without affecting drug-taking behavior in juvenile males or female offspring

The ongoing opioid addiction crisis necessitates the identification of novel risk factors to improve prevention and treatment of opioid use disorder. Parental opioid exposure has recently emerged as a potential regulator of offspring vulnerability to opioid misuse, in addition to heritable genetic liability. An understudied aspect of this "missing heritability" is the developmental presentation of these cross-generational phenotypes. This is an especially relevant question in the context of inherited addiction-related phenotypes, given the prominent role of developmental processes in the etiology of psychiatric disorders. Paternal morphine self-administration was previously shown to alter the sensitivity to the reinforcing and antinociceptive properties of opioids in the next generation. Here, phenotyping was expanded to include the adolescent period, with a focus on endophenotypes related to opioid use disorders and pain. Paternal morphine exposure did not alter heroin or cocaine self-administration in male and female juvenile progeny. Further, baseline sensory reflexes related to pain were unaltered in morphine-sired adolescent rats of either sex. However, morphine-sired adolescent males exhibited a reduction in social play behavior. Our findings suggest that, in morphine-sired male offspring, paternal opioid exposure does not affect opioid intake during adolescence, suggesting that this phenotype does not emerge until later in life. Altered social behaviors in male morphine-sired adolescents indicate that the changes in drug-taking behavior in adults sired by morphine-exposed sires may be due to more complex factors not yet fully assessed.

Examining Changes in Pain Interference via Pandemic-Induced Isolation Among Patients Receiving Medication for Opioid Use Disorder: A Secondary Data Analysis

Background

Early in the pandemic, the United States population experienced a sharp rise in the prevalence rates of opioid use, social isolation, and pain interference. Given the high rates of pain reported by patients on medication for opioid use disorder (MOUD), the pandemic presented a unique opportunity to disentangle the relationship between opioid use, pain, and social isolation in this high-risk population. We tested the hypothesis that pandemic-induced isolation would partially mediate change in pain interference levels experienced by patients on MOUD, even when controlling for baseline opioid use. Such work can inform the development of targeted interventions for a vulnerable, underserved population.

Methods

Analyses used data from a cluster randomized trial (N = 188) of patients on MOUD across eight opioid treatment programs. As part of the parent trial, participants provided pre-pandemic data on pain interference, opioid use, and socio-demographic variables. Research staff re-contacted participants between May and June 2020 and 133 participants (71% response rate) consented to complete a supplemental survey that assessed pandemic-induced isolation. Participants then completed a follow-up interview during the pandemic that again assessed pain interference and opioid use. A path model assessed whether pre-pandemic pain interference had an indirect effect on pain interference during the pandemic via pandemic-induced isolation.

Results

Consistent with hypotheses, we found evidence that pandemic-induced isolation partially mediated change in pain interference levels among MOUD patients during the pandemic. Higher levels of pre-pandemic pain interference and opioid use were both significantly associated with higher levels of pandemic-induced isolation. In addition, pre-pandemic pain interference was significantly related to levels of pain interference during the pandemic, and these pain levels were partially explained by the level of pandemic-induced isolation reported.

Conclusions

Patients on MOUD with higher use of opioids and higher rates of pain pre-pandemic were more likely to report feeling isolated during COVID-related social distancing and this, in turn, partially explained changes in levels of pain interference. These results highlight social isolation as a key risk factor for patients on MOUD and suggest that interventions promoting social connection could be associated with reduced pain interference, which in turn could improve patient quality of life.

Psychosocial functioning associated with prescription stimulant and opioid misuse versus illicit drug use among college students

Objective: College students' prescription stimulant and opioid misuse (PSM and POM) share psychosocial risks with other substance use. We sought to extend a prior study of these issues. Methods: National College Health Assessment (2015-2016) participants ages 18-24 years (n = 79,336) reporting 12-month PSM (defined as use of a drug not prescribed to them), 30-day other illicit drug use (non-cannabis), both, or neither, were compared on other substance use, psychopathology, academic adjustment, attention deficit hyperactivity disorder, and chronic pain. Models were repeated for POM. Results: Relative to those who only misused the prescription drug, those who used other illicit drugs had lower odds of chronic pain and academic problems, but higher odds on nearly every other outcome especially if they also misused the prescription drug. Conclusions: Findings suggest PSM and POM are on a continuum of risk shared with illicit drug use, but also are linked to outcomes specific to these drugs' perceived medical purposes.

Long-term Pain Symptomatology in PICU Survivors Aged 8-18 Years

BACKGROUND AND OBJECTIVES

Children discharged from the PICU often experience long-term physical, psychological, social and cognitive challenges, described as postintensive care syndrome. This study fills a critical gap by describing the long-term pain symptoms many children experience using child self-report.

METHODS

Participants in this cross-sectional study were children aged 8 to 18 years (and 1 parent, n = 64 dyads) who were 8 to 24 months post-PICU discharge. Participants completed measures assessing pain, psychosocial function, and treatment utilization. Health information relevant to the PICU admission was obtained from the electronic medical record.

RESULTS

Children were an average age of 14.3 years and 50% female. Average pain intensity in the past month was 3.65 (0-10 numeric rating scale), with 36% of children reporting pain ≥2 to 3 days a week. Youth with higher intensity (≥4) and more frequent pain (≥2-3 days a week) had greater pain catastrophizing, pain-related fear, anxiety, and sleep disturbance than those with less frequent and intense pain. Higher pain frequency was also associated with greater pain-related disability and depressive symptoms. Pain was not associated with any PICU-related variables abstracted from the electronic medical record. Parents reported children frequently accessed pain treatment services postdischarge; however, 37.5% reported the coronavirus disease 2019 pandemic impacted access to recommended services.

CONCLUSIONS

A significant portion of children experience pain post-PICU discharge. For many of these children, pain is frequent and is associated with impairments in psychosocial function. Future prospective research studies can be used to identify risk factors of poor pain outcomes so children can receive targeted interventions.

We need to talk: The urgent conversation on chronic pain, mental health, prescribing patterns and the opioid crisis

The opioid crisis’ pathways from first exposure onwards to eventual illnesses and fatalities are multiple, intertwined and difficult to dissect. Here, we offer a multidisciplinary appraisal of the relationships among mental health, chronic pain, prescribing patterns worldwide and the opioid crisis. Because the opioid crisis’ toll is especially harsh on young people, emphasis is given on data regarding the younger strata of the population. Because analgesic opioid prescription constitute a recognised entry point towards misuse, opioid use disorder, and ultimately overdose, prescribing patterns across different countries are examined as a modifiable hazard factor along these pathways of risk. Psychiatrists are called to play a more compelling role in this urgent conversation, as they are uniquely placed to provide synthesis and lead action among the different fields of knowledge and care that lie at the crossroads of the opioid crisis. Psychiatrists are also ideally positioned to gauge and disseminate the foundations for diagnosis and clinical management of mental conditions associated with chronic pain, including the identification of hazardous and protective factors. It is our hope to spark more interdisciplinary exchanges and encourage psychiatrists worldwide to become leaders in an urgent conversation with interlocutors from the clinical and basic sciences, policy makers and stakeholders including clients and their families.

"We survived the pandemic together": The impact of the COVID-19 pandemic on Canadian families living with chronic pain

Introduction

Pediatric chronic pain is a significant problem in Canada, affecting one in five youth. This study describes the impact of the pandemic on the experiences of Canadian families living with chronic pain through interviews with youth living with chronic pain, parents, and siblings.

Methods

Employing a qualitative descriptive design, in-depth semistructured interviews were completed with Canadian youth living with pain, as well as parents and siblings. Participants were not required to be related. Interviews were analyzed using a reflexive thematic analysis approach.

Results

Forty-four interviews were completed with 14 parents, 19 youth with chronic pain, and 11 siblings from across the country. Three key themes were developed: (1) absorbing and shifting: the toll of the pandemic on the family system (e.g., loss of coping mechanisms, shifting roles to respond to the pandemic), (2) social ambiguity and abandonment (e.g., social sacrifice and abandonment by the health care system), and (3) building community resilience: familial adaptation to the pandemic (e.g., family cohesion, confidence, and self-management).

Discussion/Conclusions

Youth, parents, and siblings reported that the pandemic impacted coping strategies across the family system. These results outline the challenges youth experienced managing their pain and overall health throughout the pandemic and the resilience built within families during this time. Going forward, it would be relevant to examine how racialized and structurally marginalized youth with chronic pain and their families experienced the pandemic. Future research should examine how unexpected benefits of the pandemic (e.g., increased confidence and self-management) may be sustained into the future.

A high-fat high-sugar diet and adversity early in life modulate pain outcomes at the behavioural and molecular level in adolescent rats: The role of sex

Given that adolescence is a significant period of brain plasticity and development, early life factors have the potential to alter long term outcomes. For instance, adversities such as consumption of a high-fat high-sugar (HFHS) diet and adverse childhood experiences (ACEs; e.g., neglect), and their resulting inflammation and microglial activation can influence pain outcomes by priming the neuroimmune system to overrespond to stressors. Chronic pain is highly prevalent amongst the adolescent population, with the prevalence and manifestation being sexually dimorphic. Although clinical studies show that females are twice as likely to report pain problems compared to males, the majority of pre-clinical work uses male rodents. Therefore, our aim was to examine the effects of sex, a HFHS diet, and an ACE on chronic pain outcomes following a stressor in adolescence. Rat dams were randomly assigned to a Standard or HFHS diet, with pups maintained on their respective diets then randomly allocated to a No Stress or ACE paradigm, and a Sham or Injury condition as a stressor. Results showed that early life adversities increased nociceptive sensitivity, inflammation, and microglial activation systemically and within the brain. Behaviourally, pain outcomes were more prominent in females, however the neuroimmune response was exacerbated in males. These results demonstrate the sexual dimorphism of chronic pain outcomes following early life adversities and provide insight into the mechanisms driving these changes, which will inform more targeted and effective treatment strategies for youth living with chronic pain.

Chronic pain in children and adolescents in Manitoba: A retrospective chart review to inform the development of a provincial service for pediatric chronic pain

Background

In the absence of an interdisciplinary service for pediatric chronic pain in Manitoba, pain management has been offered through a single provider outpatient setting with consultative services from physiotherapy, occupational therapy, and psychiatry since October 2015.

Aims

The aim of this study was to characterize the patient population of this clinic to understand needs and inform future service development for pediatric chronic pain.

Methods

Demographics and disease characteristics of all patients seen in this clinic between October 1, 2015, and February 28, 2019, were analyzed retrospectively from electronic medical records.

Results

A total of 157 patients, mean age 13.1 (sd ±3.0) years, 75.2% female, with a median duration of pain of 20.5 (interquartile range [IQR] = 10.0–45.8) months at their first visit were included in the study. At baseline, 74.0% of patients experienced insomnia, 76.6% fatigue, 86.5% symptoms of anxiety, and 58.69% symptoms of depression; 80.1% showed withdrawal from physical activity, 67.1% missed school, and 10.2% reported opioid usage. Throughout their care in clinic, 83.4% of patients received physiotherapy, 17.8% occupational therapy, 49.7% mental health support, and 51.6% care from multiple services. The clinic experienced a significant increase in median referrals from 1.0 to 5.0 (IQR = 2.0–9.0) per month and wait time from 35.0 to 97.0 (IQR = 88.0–251.0) days during the observation period.

Conclusions

Developing an interdisciplinary service for pediatric chronic pain will provide an opportunity to improve access, coordination, and comprehensiveness of care and to employ culturally sensitive services to improve care for children and youth living with chronic pain in Manitoba and possibly other jurisdictions with similar demographics and needs.

Identifying and Managing Suicidality in Children and Adolescents with Chronic Pain: Evidence-Based Treatment Strategies

Children and adolescents with chronic pain are at an increased risk of suicidality. This narrative review article aims to inform clinical practice in the assessment and management of suicidality in youth with chronic pain. The article begins with a survey of the background and prevalence of youth with chronic pain. A review of the current evidence behind the increased risk of suicidality in youth with chronic pain follows. Contextualization of this data with general tenets of child and adolescent suicide risk and risk assessment is provided. Suicidology theory including the interpersonal theory of suicide is overviewed to help clinicians to conceptualize the reviewed data. Guiding parameters for the suicide risk assessment and management planning is presented. Concluding recommendations are made to guide clinical practice in the assessment and management of suicidality in youth with chronic pain.

Pain, depressive symptoms, and health-related quality of life among survivors of pediatric hematopoietic stem cell transplant

OBJECTIVE

Pediatric hematopoietic stem cell transplant (HCT) is an intensive medical procedure associated with significant late effects, of which pain is a prominent example. While pain is associated with increased depressive symptoms and health-related quality-of-life (HRQoL) impairments in other pediatric chronic illness populations, associations between these variables are not well understood in pediatric HCT. Clarifying these associations may inform clinical interventions to improve health outcomes following pediatric HCT. This study aimed to investigate the relations between pain intensity, depressive symptoms, and HRQoL in survivors of pediatric HCT.

METHOD

Fifty-one survivors of pediatric HCT (Mage  = 14.3 years, standard deviation [SD] = 4.3; 58.8% male; 80.4% White) completed self-report measures of pain intensity, depressive symptoms, and HRQoL. Demographic and disease information was collected via demographic forms and medical record review. Path analysis was used to examine hypothesized associations between pain intensity, depressive symptoms, and HRQoL.

RESULTS

Analyses revealed direct effects of pain intensity on depressive symptoms (estimate [Est.] = .23, p < .001) and HRQoL (Est. = -.2, p = .04), and direct effects of depressive symptoms on HRQoL (Est. = -.68, p < .001). Depressive symptoms also mediated the relationship between pain intensity and HRQoL (Est. = -.16, p = .006).

CONCLUSIONS

Greater pain intensity was associated directly with increased depressive symptoms and indirectly with HRQoL through depressive symptoms. Results of this study suggest that multitargeted cognitive behavioral interventions that address pain and depressive symptoms may improve HRQoL ratings in survivors of pediatric HCT.

Mindfulness-Oriented Recovery Enhancement for Addictive Behavior, Psychiatric Distress, and Chronic Pain: A Multilevel Meta-Analysis of Randomized Controlled Trials

Objectives

Mindfulness-Oriented Recovery Enhancement (MORE) is an integrative intervention designed to ameliorate addiction, chronic pain, and psychiatric symptoms. Although multiple randomized controlled trials (RCTs) have examined the clinical efficacy of MORE, no study has quantitatively synthesized this body of research. Thus, we conducted a meta-analysis of RCTs examining the effects of MORE on addictive behaviors, craving, opioid dose, pain, and psychiatric symptoms.

Methods

Relevant manuscripts were identified through comprehensive searches of four bibliographic databases. Two- and three-level random-effects models were used to generate synthesized effect size estimates, and meta-regressions were performed to examine whether study and sample characteristics influenced the magnitude of aggregate effect sizes.

Results

Our search identified 16 manuscripts reporting data from eight RCTs (N = 816). Moderate to small effects in favor of MORE were observed for addictive behaviors (SMC =  - .54, p = .007), craving (SMC =  - .42, p = .010), opioid dose (MC =  - 17.95, p < .001), chronic pain (SMC =  - .60, p < .001), and psychiatric symptoms (SMC =  - .34, p < .001). MORE's effects on psychiatric symptoms and craving were not moderated by participant race, gender, age, or income.

Conclusions

Study findings provide empirical evidence of MORE's efficacy for a wide diversity of individuals, and as such, MORE should now be disseminated broadly throughout the healthcare system.

ARMADILLO REGULATES NOCICEPTIVE SENSITIVITY IN THE ABSENCE OF INJURY

Abnormal pain has recently been estimated to affect ∼50 million adults each year within the United States. With many treatment options for abnormal pain, such as opioid analgesics, carrying numerous deleterious side effects, research into safer and more effective treatment options is crucial. To help elucidate the mechanisms controlling nociceptive sensitivity, the Drosophila melanogaster larval nociception model has been used to characterize well-conserved pathways through the use of genetic modification and/or injury to alter the sensitivity of experimental animals. Mammalian models have provided evidence of β-catenin signaling involvement in neuropathic pain development. By capitalizing on the conserved nature of β-catenin functions in the fruit fly, here we describe a role for Armadillo, the fly homolog to mammalian β-catenin, in regulating baseline sensitivity in the primary nociceptor of the fly, in the absence of injury, using under- and over-expression of Armadillo in a cell-specific manner. Underexpression of Armadillo resulted in hyposensitivity, while overexpression of wild-type Armadillo or expression of a degradation-resistant Armadillo resulted in hypersensitivity. Neither underexpression nor overexpression of Armadillo resulted in observed dendritic morphological changes that could contribute to behavioral phenotypes observed. These results showed that focused manipulation of Armadillo expression within the nociceptors is sufficient to modulate baseline response in the nociceptors to a noxious stimulus and that these changes are not shown to be associated with a morphogenetic effect.

Young Adult Healthcare Exposure and Future Opioid Misuse: A Prospective Cohort Study

INTRODUCTION

Outpatient opioid prescribing is associated with opioid misuse in young adults, but the longitudinal association between general healthcare exposure and opioid misuse has not been explored. The objective of this study is to examine the association between healthcare exposure in young adulthood and future opioid misuse.

METHODS

Data were drawn from the National Longitudinal Study of Adolescent to Adult Health (2001-2018) and analyzed in 2021. Healthcare exposure (i.e., inpatient hospitalization and visits to the clinic, emergency department, mental-health facility, or dentist) between individuals aged 18 and 26 years was the primary independent variable; only patients who did not report opioid misuse at baseline were included. Opioid misuse was defined as using prescription painkillers without a doctor's permission and was measured 17 years after exposure. Multivariable logistic regression was used to examine any associations with opioid misuse (ages 33-43 years).

RESULTS

A total of 8,225 young adults with a mean baseline age of 21.8 (SE=0.12) years met inclusion criteria. Approximately 13.7% reported new opioid misuse at follow-up. Those reporting opioid misuse at follow-up were more likely to be White, lack a college education, or report depression. Those exposed to inpatient hospitalization, emergency departments, or mental-health facilities had an increased risk of future opioid misuse.

CONCLUSIONS

In young adults reporting no opioid misuse at baseline, healthcare exposure was associated with an increased risk of opioid misuse later in adulthood in this large, national cohort. Physicians encounter this at-risk population daily, reinforcing the importance of responsible prescribing practices and the need for targeted screening, patient education, and intervention efforts in the healthcare setting.

Impact of endometriosis on women's life decisions and goal attainment: a cross-sectional survey of members of an online patient community

OBJECTIVES

To examine women's perceptions of endometriosis-associated disease burden and its impact on life decisions and goal attainment.

DESIGN

An anonymous online survey was distributed in October 2018 through the social media network MyEndometriosisTeam.com.

PARTICIPANTS

Women aged 19 years and older living in several English-speaking countries who self-identified as having endometriosis.

OUTCOME MEASURES

Patients' perspectives on how endometriosis has affected their work, education, relationships, overall life decisions and attainment of goals. Subanalyses were performed for women who identified as 'less positive about the future' (LPAF) or had 'not reached their full potential' (NRFP) due to endometriosis.

RESULTS

743 women completed the survey. Women reported high levels of pain when pain was at its worst (mean score, 8.9 on severity scale of 0 (no pain) to 10 (worst imaginable pain)) and most (56%, n=415) experienced pain daily. Women reported other negative experiences attributed to endometriosis, including emergency department visits (66%, n=485), multiple surgeries (55%, n=406) and prescription treatments for symptoms of endometriosis (72%, n=529). Women indicated that they believed endometriosis had a negative impact on their educational and professional achievements, social lives/relationships and overall physical health. Most women 'somewhat agreed'/'strongly agreed' that endometriosis caused them to lose time in life (81%, n=601), feel LPAF (80%, n=589) and feel they had NRFP (75%, n=556). Women who identified as LPAF or NRFP generally reported more negative experiences than those who were non-LPAF or non-NRFP.

CONCLUSIONS

Women who completed this survey reported pain and negative experiences related to endometriosis that were perceived to negatively impact major life-course decisions and attainment of goals. Greater practitioner awareness of the impact that endometriosis has on a woman's life course and the importance of meaningful dialogue with patients may be important for improving long-term management of the disease and help identify women who are most vulnerable.

Prevalence and Characteristics of Muscle Tightness in Young Adults

In young adults, muscle sprains and strains leading to muscle tightness are considered short-term and believed to have no ill effects on quality of life. However, recent advances in the science indicate that muscle tightness is an invisible condition that can limit life activities. The objective of this study was to identify the prevalence and characteristics of muscle tightness in young adults. The study used descriptive quantitative design. One hundred individuals aged between 18 and 27 years completed a survey based upon a validated muscle tightness measurement tool. Seventy-two percent of participants reported experiencing muscle tightness that limited their daily living and recreational activities. Fifty-six percent reported experiencing pain with muscle tightness. Women were more likely than men to experience muscle tightness. Awareness, prompt evaluation, and treatment of this condition are key to preventing negative consequences associated with chronic muscle tightness.

Mapping the current state of pediatric surgical pain care across Canada and assessing readiness for change

Background

Preventing pediatric chronic postsurgical pain is a patient, parent/caregiver, health care professional, and policymaker priority. Poorly managed presurgical and acute postsurgical pain are established risk factors for pediatric chronic postsurgical pain. Effective perioperative pain management is essential to prevent the transition from acute to chronic pain after surgery.

Aims

The aim of this study was to identify current pediatric surgical pain management practices and assess health system readiness for change at health care institutions conducting pediatric surgery in Canada.

Methods

An online survey was completed by 85 multidisciplinary health care professionals (nurses, surgeons, anesthesiologists, allied health) from 20 health institutions in Canada regarding institutional pre- and postsurgical pediatric pain care, specialty pain services, and Organizational Readiness for Implementing Change (ORIC).

Results

Of all specialty pain services, acute and chronic/complex pain services were most common, primarily with physician and nursing involvement. Alignment to recommended practices for pediatric pre- and postsurgical pain care varied (38.1%–79.8% reported “yes, for every child”), with tertiary/quaternary children’s hospitals reporting less alignment than other institutions (community/regional or rehabilitation hospitals, community treatment centers). No significant differences were reported between health care institutions serving pediatric populations only versus those also serving adults. Health care professional experience/practice was the most reported strength in pediatric surgical pain care, with inconsistent standard of care the most common gap. Participants “somewhat agreed” that their institutions were committed and capable of change in pediatric surgical pain care.

Conclusions

There is a continued need to improve pediatric pain care during the perioperative period at Canadian health care institutions to effectively prevent the development of pediatric postsurgical pain.

Subtypes in Patients Taking Prescribed Opioid Analgesics and Their Characteristics: A Latent Class Analysis

BACKGROUND

Owing to their pharmacological properties the use of opioid analgesics carries a risk of abuse and dependence, which are associated with a wide range of personal, social, and medical problems. Data-based approaches for identifying distinct patient subtypes at risk for prescription opioid use disorder in Germany are lacking.

OBJECTIVE

This study aimed to identify distinct subgroups of patients using prescribed opioid analgesics at risk for prescription opioid use disorder.

METHODS

Latent class analysis was applied to pooled data from the 2015 and 2021 Epidemiological Survey of Substance Abuse. Participants were aged 18-64 years and self-reported the use of prescribed opioid analgesics in the last year (n = 503). Seven class-defining variables based on behavioral, mental, and physical health characteristics commonly associated with problematic opioid use were used to identify participant subtypes. Statistical tests were performed to examine differences between the participant subtypes on sociodemographic variables and prescription opioid use disorder.

RESULTS

Three classes were extracted, which were labeled as poor mental health group (43.0%, n = 203), polysubstance group (10.4%, n = 50), and relatively healthy group (46.6%, n = 250). Individuals within the poor mental health group (23.2%, n = 43) and the polysubstance group (31.1%, n = 13) showed a higher prevalence of prescription opioid use disorder compared to those of the relatively healthy group.

CONCLUSION

The results add further evidence to the knowledge that patients using prescribed opioid analgesics are not a homogeneous group of individuals whose needs lie in pain management alone. Rather, it becomes clear that these patients differ in their individual risk of a prescription opioid use disorder, and therefore identification of specific risks plays an important role in early prevention.

Rates and Predictors of Using Opioids in the Emergency Department to Treat Migraine in Adolescents and Young Adults

OBJECTIVES

This study aimed to determine the rate and context in which opioids are used to treat migraine in adolescents and young adults seen in emergency care settings.

METHODS

Data from 2010 to 2016 in the Cerner Health Facts electronic health record data warehouse were analyzed using multilevel logistic regression to estimate the population likelihood of an opioid being used in the emergency department (ED) to treat a primary diagnosis of migraine in adolescents and young adults and to evaluate the extent to which this likelihood varies as a function of characteristics of the patient (age, sex, race, and insurance), encounter (referral source, provider specialty, and encounter duration and year), and ED (region, setting, size, payer mix, and academic status).

RESULTS

The study identified 14,494 eligible ED encounters with unique patients, of which 23% involved an opioid. Likelihood of being treated with opioids was significantly higher for patients who were older, female, white, and seen by a surgeon and who had longer encounters and encounters earlier in the time period sampled. Sites varied widely in percentage of encounters involving opioids (mean, 26.4% ± 20.1%; range, 0-100%), with higher rates associated with smaller sites with relatively higher proportions of commercially insured patients.

CONCLUSIONS

Use of opioids in the ED to treat migraine in youth is fairly common, with rate variation reflecting broader trends in for whom opioids tend to be more likely to be prescribed. These findings may be helpful for benchmarking and informing quality improvement efforts aimed at reducing unwarranted opioid exposure in youth.

Nonmedical Opioid Use After Short-term Therapeutic Exposure in Children: A Systematic Review

CONTEXT

Opioid-related harms continue to rise for children and youth. Analgesic prescribing decisions are challenging because the risk for future nonmedical opioid use or disorder is unclear.

OBJECTIVE

To synthesize research examining the association between short-term therapeutic opioid exposure and future nonmedical opioid use or opioid use disorder and associated risk factors.

DATA SOURCES

We searched 11 electronic databases.

STUDY SELECTION

Two reviewers screened studies. Studies were included if: they were published in English or French, participants had short-term (≤14 days) or an unknown duration of therapeutic exposure to opioids before 18 years, and reported opioid use disorder or misuse.

DATA EXTRACTION

Data were extracted, and methodologic quality was assessed by 2 reviewers. Data were summarized narratively.

RESULTS

We included 21 observational studies (49 944 602 participants). One study demonstrated that short-term therapeutic exposure may be associated with opioid abuse; 4 showed an association between medical and nonmedical opioid use without specifying duration of exposure. Other studies reported on prevalence or incidence of nonmedical use after medical exposure to opioids. Risk factors were contradictory and remain unclear.

LIMITATIONS

Most studies did not specify duration of exposure and were of low methodologic quality, and participants might not have been opioid naïve.

CONCLUSIONS

Some studies suggest an association between lifetime therapeutic opioid use and nonmedical opioid use. Given the lack of clear evidence regarding short-term therapeutic exposure, health care providers should carefully evaluate pain management options and educate patients and caregivers about safe, judicious, and appropriate use of opioids and potential signs of misuse.

Associations between insufficient sleep and prescription opioid misuse among high school students in the United States

STUDY OBJECTIVES

The aim of this study was to estimate the association between insufficient sleep and prescription opioid misuse among US high school students.

METHODS

Participants were 6,884 high school students who self-reported on sleep duration and prescription opioid misuse in the 2019 Youth Risk Behavior Survey. Sleep duration was categorized by the Youth Risk Behavior Survey according to the American Academy of Sleep Medicine guidelines as follows: recommended sleep duration (8-9 hours) vs insufficient sleep (< 8 hours). Participants also reported whether they had any prescription opioid misuse during their lifetime and whether they had prescription opioid misuse within the past 30 days.

RESULTS

Most (79.4%) participants reported sleeping less than 8 hours per night. Among all youth, 12.9% reported lifetime prescription opioid misuse and 6.2% reported current prescription opioid misuse. Prevalence of both lifetime and current opioid medication misuse was higher among those also reporting insufficient sleep compared to those reporting recommended sleep duration (14.3% vs 7.7%, P < .0001 for lifetime misuse and 6.6% vs 4.3%, P = .0091 for current misuse). In multivariate models, insufficient sleep was associated with an increased odds of lifetime prescription opioid misuse (adjusted odds ratios = 1.4; 95% confidence interval, 1.1-1.2; P = .006); however, we did not find an association between sleep duration and current prescription opioid misuse in multivariate analysis.

CONCLUSIONS

Sleep duration is associated with lifetime opioid misuse among US youth. Longitudinal studies are needed to test whether causal relationships exist, and to understand biobehavioral mechanisms that underlie associations between sleep deficiency and opioid misuse in adolescents.
