Exposure to childhood trauma increases risk of opioid use disorder among people prescribed opioids for chronic non-cancer pain

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.

Identifying patterns of pain, depression, anxiety, interpersonal trauma exposure, and nonmedical prescription opioid use: Latent class analysis among patients with chronic pain

BACKGROUND

Chronic pain in the context of certain factors may be associated with potential for nonmedical prescription opioid use; however, identifying this risk can be challenging and complex. Several variables alone have been associated with non-prescribed opioid use, including depression, anxiety, pain interference, and trauma exposure. Prior research has often failed to integrate these assessments together, which is important as these factors may cluster together in important and complex ways. The current study aimed to identify classes of patients with chronic pain who have differential risk for use of nonmedical prescription opioid use, depression and anxiety, and pain severity, interference, and catastrophizing, and interpersonal violence exposure.

METHODS

Self-report and medical record data from patients (N = 211; Mage = 48, 69.0% women, 69.0% white) at a pain management center were collected.

RESULTS

Latent class analysis revealed 3 classes with (1) low probability of clinically significant depression, anxiety, pain, and nonmedical prescription opioid use (44.7%), (2) high probability of clinically significant depression, anxiety, pain, pain catastrophizing, trauma, and nonmedical prescription opioid use (41.3%), and (3) high probability of severe pain and nonmedical prescription opioid use (14.0%).

CONCLUSIONS

High-risk classes had either high levels of depression and anxiety, pain catastrophizing, and interpersonal violence exposure, or pain severity and interference. Future research should continue to explore these classes in large, diverse samples, and prospective study designs. Finally, results underscore that opioid use is complex, not easily identified by a single factor, and may be motivated by complex unmet clinical needs.

Adverse childhood experience is associated with an increased risk of reporting chronic pain in adulthood: a stystematic review and meta-analysis

Background: Adverse childhood experiences (ACEs) have been shown to negatively affect health in adulthood. Estimates of associations between ACEs and chronic painful conditions are lacking.Objectives: This systematic review and meta-analysis aimed to evaluate associations between exposure to ACEs and chronic pain and pain-related disability in adults.Methods: We searched 10 electronic databases from inception to February 2023. We included observational studies assessing associations between direct ACEs (childhood sexual, physical, emotional abuse, or neglect) alone or in combination with indirect ACEs (witnessing domestic violence, household mental illness), and adult chronic pain (≥3 months duration) and pain-related disability (daily activities limited by chronic pain). Pairs of reviewers independently extracted data and assessed study risks of bias. Random-effect models were used to calculate pooled adjusted odds ratios [aOR]. Tau square [T2], 95% prediction intervals [95%PI] and I2 expressed the amount of heterogeneity, and meta-regressions and subgroup meta-analyses investigated sources of heterogeneity (PROSPERO: CRD42020150230).Results: We identified 85 studies including 826,452 adults of which 57 studies were included in meta-analyses. Study quality was generally good or fair (n = 70). The odds of reporting chronic pain in adulthood were significantly higher among individuals exposed to a direct ACE (aOR, 1.45, 95%CI, 1.38-1.53). Individuals reporting childhood physical abuse were significantly more likely to report both chronic pain (aOR, 1.50, 95CI, 1.39-1.64) and pain-related disability (1.46, 95CI, 1.03-2.08) during adulthood. Exposure to any ACEs alone or combined with indirect ACEs significantly increase the odds of adult chronic painful conditions (aOR, 1.53, 95%CI, 1.42-1.65) and pain-related disability (aOR, 1.29; 95%CI, 1.01-1.66). The risk of chronic pain in adulthood significantly increased from one ACE (aOR, 1.29, 95%CI, 1.22-1.37) to four or more ACEs (1.95, 95%CI, 1.73-2.19).Conclusions: Single and cumulative ACEs are significantly associated with reporting of chronic pain and pain-related disability as an adult.

Accounting for the interplay of interpersonal and structural trauma in the treatment of chronic non-cancer pain, opioid use disorder, and mental health in urban safety-net primary care clinics

While the epidemiological literature recognizes associations between chronic non-cancer pain (CNCP), opioid use disorder (OUD), and interpersonal trauma stemming from physical, emotional, sexual abuse or neglect, the complex etiologies and interplay between interpersonal and structural traumas in CNCP populations are underexamined. Research has documented the relationship between experiencing multiple adverse childhood experiences (ACEs) and the likelihood of developing an OUD as an adult. However, the ACEs framework is criticized for failing to name the social and structural contexts that shape ACE vulnerabilities in families. Social scientific theory and ethnographic methods offer useful approaches to explore how interpersonally- and structurally-produced traumas inform the experiences of co-occurring CNCP, substance use, and mental health. We report findings from a qualitative and ethnographic longitudinal cohort study of patients with CNCP (n = 48) who received care in safety-net settings and their primary care providers (n = 23). We conducted semi-structured interviews and clinical and home-based participant observation from 2018 to 2020. Here we focus our analyses on how patients and providers explained and situated the role of patient trauma in the larger clinical context of reductions in opioid prescribing to highlight the political landscape of the United States opioid overdose crisis and its impact on clinical interactions. Findings reveal the disproportionate burden structurally-produced, racialized trauma places on CNCP, substance use and mental health symptoms that shapes patients' embodied experiences of pain and substance use, as well as their emotional experiences with their providers. Experiences of trauma impacted clinical care trajectories, yet providers and patients expressed limited options for redress. We argue for an adaptation of trauma-informed care approaches that contextualize the structural determinants of trauma and their interplay with interpersonal experiences to improve clinical care outcomes.

Prevention of Opioid Use and Disorder Among Youth Involved in the Legal System: Innovation and Implementation of Four Studies Funded by the NIDA HEAL Initiative

Youth involved in the legal system (YILS) experience rates of opioid and substance use disorders (OUD/SUDs) and overdose that is well above those in the general population. Despite the dire need, and the existing programs that focus on treatment of these problems in YILS, research on opioid initiation, and OUD prevention, including feasibility and sustainability, are severely limited. We present four studies testing interventions that, while not necessarily novel as SUD treatments, test novel structural and interpersonal strategies to prevent opioid initiation/OUD precursors: (1) ADAPT (Clinical Trial No. NCT04499079) provides real-time feedback using community-based treatment information system data to create a more effective mental health and SUD treatment cascade to prevent opioid use; (2) HOME (Clinical Trial No. NCT04135703) provides youth experiencing homelessness, including YILS, with direct access to shelter in independent living without prerequisites as an opioid initiation prevention strategy; (3) LeSA (Clinical Trial No. NCT04678960) uses the Trust-Based Relational Intervention® to equip YILS and their caregivers with self-regulatory and communication skills during the transition from secure confinement to reduce opioid initiation/re-initiation; and (4) POST (Clinical Trial No. NCT04901312) tests two interventions integrating interpersonal/drinking and drug refusal skills, case management, and goal setting among YILS in transitioning out of secure detention as opioid initiation prevention strategies. We discuss early implementation barriers and facilitators, including complexities of prevention research with YILS and adaptations due to COVID-19. We conclude by describing anticipated end products, including implementation of effective prevention interventions and integration of data from multiple projects to address larger, multi-site research questions.

What is the association between childhood adversity and subsequent chronic pain in adulthood? A systematic review

Background

Adverse childhood experiences and chronic pain are complex problems affecting millions of people worldwide, and result in significant healthcare utilisation. Our review aimed to determine known associations between adversity in childhood and chronic pain in adulthood.

Methods

We performed a prospectively registered systematic review (PROSPERO ID: 135625). Six electronic databases (Pubmed, Medline, Cochrane, Scopus, APA PsycNet, Web of Science) were searched from January 1, 2009 until May 30, 2022. Titles and abstracts were screened, and all original research studies examining associations between adverse childhood experiences and chronic pain in adulthood were considered for inclusion. Full texts were reviewed, and a narrative synthesis was used to identify themes from extracted data. Ten percent of studies were dual reviewed to assess inter-rater reliability. Quality assessment of study methodology was undertaken using recognised tools.

Results

Sixty-eight eligible studies describing 196 130 participants were included. Studies covered 15 different types of childhood adversity and 10 different chronic pain diagnoses. Dual reviewed papers had a Cohen's kappa reliability rating of 0.71. Most studies were of retrospective nature and of good quality. There were consistent associations between adverse childhood experiences and chronic pain in adulthood, with a 'dose'-dependent relationship. Poor mental health was found to mediate the detrimental connection between adverse childhood experiences and chronic pain.

Conclusion

A strong association was found between adverse childhood experiences and chronic pain in adulthood. Adverse childhood experiences should be considered in patient assessment, and early intervention to prevent adverse childhood experiences may help reduce the genesis of chronic pain. Further research into assessment and interventions to address adverse childhood experiences is needed.

The effects of childhood trauma and mental disorders on treatment engagement, contact with the criminal justice system, and mortality among people with opioid dependence

BACKGROUND

Childhood trauma and mental disorders increase the risk of opioid dependence. We aimed to examine whether childhood trauma and mental disorders are associated with opioid agonist treatment (OAT) engagement, contact with the criminal justice system, and mortality among people with opioid dependence.

METHODS

This observational study linked survey data from 1482 people receiving OAT in Sydney, Australia (2004-2008) to administrative data on OAT, crime, and mortality through 2017. We used survey data to assess childhood trauma, depression, panic disorder, post-traumatic stress disorder (PTSD), borderline personality disorder, anti-social personality disorder (ASPD), and comorbid substance dependence. We used discrete-time analysis to examine time from opioid dependence onset to OAT entry and mortality. Poisson regressions were used to analyze time receiving OAT and number of charges.

RESULTS

Participants with extensive childhood trauma histories and ASPD were less likely to enter OAT and those with depression were more likely to enter OAT in any given year after opioid dependence onset. Panic disorder, PTSD, and borderline personality disorder were associated with less time in OAT. Extensive histories of childhood trauma, PTSD, ASPD, and comorbid substance dependence increased risk of charges for any offence. There were no significant associations between the exposure variables and mortality.

CONCLUSIONS

Our findings suggest that childhood trauma and mental disorders increase the risk of adverse treatment and social outcomes among people with opioid dependence. Interventions that aim to reduce harm among people with opioid dependence may consider the effect of childhood trauma and mental disorders on OAT engagement and crime.

Prevalence of mental disorders among people with opioid use disorder: A systematic review and meta-analysis

BACKGROUND

Opioid use disorder (OUD) and mental disorders are major public health issues and comorbidity is common. Among people with OUD, comorbid mental disorders are associated with poorer health outcomes. To our knowledge, this is the first systematic review and meta-analysis to estimate prevalence of specific mental disorders among people with OUD.

METHODS

We searched Embase, MEDLINE, and PsycInfo from 1990 to 2021 for observational studies of depression, anxiety, post-traumatic stress disorder (PTSD), bipolar, personality, and other pre-specified mental disorders among people with OUD. We pooled current and lifetime estimates of each disorder using random-effects meta-analyses with 95% Confidence Intervals (CIs). Meta-regressions and stratified analyses were used to assess heterogeneity of prevalence estimates by methodological factors and sample characteristics.

FINDINGS

Of the 36,971 publications identified, we included data from 345 studies and 104,135 people with OUD in at least one pooled estimate. Among people with OUD, the prevalence of current depression was 36.1% (95%CI 32.4-39.7%), anxiety was 29.1% (95%CI 24.0-33.3%), attention-deficit/hyperactivity disorder was 20.9% (95%CI 15.7-26.2%), PTSD was 18.1% (95%CI 15.4-20.9%), and bipolar disorder was 8.7% (95%CI 6.7-10.7%). Lifetime prevalence of anti-social personality disorder was 33.6% (95%CI 29.1-38.0%) and borderline personality disorder was 18.2% (95% CI 13.4-23.1%). Sample characteristics and methodological factors, including sex, were associated with variance of multiple prevalence estimates.

INTERPRETATION

Our findings emphasise the need for access to mental disorder treatment among people with OUD. Specific mental disorder estimates may inform clinical guidelines, treatment services, and future research for people with OUD, including subpopulations with distinct treatment needs.
