Co-occurring prescription opioid use problems and posttraumatic stress disorder symptom severity

Prevalence of Opioid Use Disorder and Opioid Overdose Rates Among People With Mental Illness

OBJECTIVE

The authors examined the prevalence and correlates of co-occurring opioid use disorder and opioid overdose among individuals receiving psychiatric services.

METHODS

This was a cross-sectional study of adults with continuous enrollment in New York State Medicaid who received at least one psychiatric service in 2020 (N=523,885). Logistic regression models were used to examine the correlates of both opioid use disorder and overdose.

RESULTS

In the study sample, the prevalence rate of opioid use disorder was 8.1%; within this group, 7.7% experienced an opioid overdose in the study year. Opioid use disorder rates were lower among younger (18-24 years; 2.0%) and older (≥65 years; 3.1%) adults and higher among men (11.1%) and among those residing in rural areas (9.9%). Compared with Whites (9.4%), opioid use disorder rates were lower for Asian Americans (2.0%, adjusted odds ratio [AOR]=0.22) and Blacks (6.8%, AOR=0.76) and higher for American Indians (13.2%, AOR=1.43) and Hispanics (9.6%, AOR=1.29). Individuals with any substance use (24.9%, AOR=5.20), posttraumatic stress (15.7%, AOR=2.34), bipolar (14.9%, AOR=2.29), or anxiety (11.3%, AOR=2.18) disorders were more likely to have co-occurring opioid use disorder; those with conduct (4.5%, AOR=0.51), adjustment (7.4%, AOR=0.88), or schizophrenia spectrum (7.4%, AOR=0.87) disorders were less likely to have opioid use disorder. Those with suicidality (23.9%, AOR=3.83) or economic instability (23.7%, AOR=3.35) had higher odds of having opioid use disorder. Overdose odds were higher among individuals with suicidality (34.0%, AOR=6.82) and economic instability (16.0%, AOR=2.57).

CONCLUSIONS

These findings underscore the importance of providing opioid use disorder screening and treatment for patients receiving psychiatric services.

Reported Increase in Substance Use Following Mass Terrorism and the Role of Psychosocial Factors

Importance

Research has shown evidence of increased substance use (ISU) in populations affected by mass terrorism; however, less is known regarding how psychosocial factors interact to estimate ISU following such events.

Objective

To examine which factors are associated with reporting ISU, test whether psychological distress (PD) mediated the association between exposure to trauma and reporting ISU, and whether the mediation effect differed among those with prior mental health (MH) difficulties and those without.

Design, Setting, and Participants

A partially representative cross-sectional survey of the adult Jewish population in Israel (aged 18-70 years) was conducted 4 weeks after October 7, 2023 (October 31 to November 5, 2023). A national Web panel using quotas based on national distributions was used. Randomly chosen adult Jewish members were invited to participate until a predetermined sample size was reached.

Main Outcomes and Measures

The study measures included reporting ISU (outcome), PD (mediator), exposure to terror events and sociodemographic characteristics (variables), and prior MH difficulties (moderator). Hypotheses regarding outcome and variables were formulated before data collection.

Results

A total of 7000 invitations were distributed, 2679 individuals consented, 1432 were excluded owing to quota limits, 74 failed attention tests, and 205 opted out, resulting in 968 participants (490 women [50.6%]; mean [SD] age, 41.5 [14.6] years). Hierarchical regression analysis revealed that participants were significantly more likely to report ISU if they had experienced direct exposure (odds ratio [OR], 5.75; 95% CI, 2.53 to 13.05), indirect exposure (OR, 1.84; 95% CI, 1.27 to 2.67), media exposure (OR, 1.22; 95% CI, 1.09 to 1.36), PD (OR, 1.80; 95% CI, 1.44 to 2.25), or previous MH difficulties (OR, 2.76; 95% CI, 1.86 to 4.09). PD partially mediated the association between indirect exposure (b = 0.20; 95% CI, 0.11 to 0.31) and media exposure (b = 0.14; 95% CI, 0.10 to 0.19) and reporting ISU. No evidence was found to support previous MH difficulties as a moderator of these indirect effects (indirect exposure, b = -0.003; 95% CI, -0.28 to 0.28; media exposure, b = 0.01; 95% CI, -0.06 to 0.08).

Conclusions and Relevance

This study contributes to the research on the association of mass terrorism with ISU while shedding important light on the role it may play in the self-medication of PD following exposure, even in those who might have no previous MH difficulties. These insights are crucial for planning essential health services and preventive measures.

Posttraumatic Stress and Opioid Use and Pain among Individuals with Probable Posttraumatic Stress Disorder and Self-Reported Chronic Pain: The Role of Health Literacy

BACKGROUND

Chronic pain and opioid misuse are a prevalent comorbidity with deleterious health outcomes. Growing work indicates that posttraumatic stress disorder (PTSD) can increase the risk for chronic pain and opioid misuse and dependence. However, there is little understanding of social determinants of health (SDoH) that may account for interrelations of PTSD with chronic pain and opioid misuse and dependence. Health literacy is one relevant SDoH construct, reflecting the ability to gather, process, and comprehend health-related information required to engage in a healthcare setting.

OBJECTIVE

The purpose of the present cross-sectional study was to examine the indirect effect of health literacy in the association between PTSD and opioid misuse, opioid dependence, pain intensity, and pain disability.

METHOD

The sample included 142 adults (Mage = 35.2, SD = 9.9; 67.4% female; 70.1% White/Caucasian) with self-reported chronic pain and probable PTSD who were using opioid medication.

RESULTS

Results demonstrated that PTSD symptom severity had a small indirect effect on opioid misuse and opioid dependence via health literacy; no indirect effects were evident for pain intensity and disability.

CONCLUSION

The present investigation provides evidence that health literacy may serve as an important explanatory factor in associations between PTSD symptom severity and opioid misuse and dependence among adults with co-occurring probable PTSD and chronic pain.

The effect of combat deployments on veteran opioid abuse

Grim national statistics about the U.S. opioid crisis are increasingly well known to the American public. Far less well known is that U.S. servicemembers are at ground zero of the epidemic, with veterans facing an overdose death rate of up to twice that of civilians. Exploiting a quasi-experiment in overseas deployment assignment, this study estimates the causal impact of combat exposure among the deployed in the Global War on Terrorism on opioid abuse. We find that exposure to war theater substantially increased the risk of prescription painkiller abuse and illicit heroin use among active duty servicemen. The magnitudes of our estimates imply lower-bound combat exposure-induced healthcare costs of $1.04 billion per year for prescription painkiller abuse and $470 million per year for heroin use.

Trauma-related shame predicts daily non-medical prescription opioid use among individuals with PTSD symptoms

Non-medical prescription opioid use (NMPOU) is the use of opioids without a prescription or in a way different from how they were prescribed and is the fourth most common type of drug use in the United States. Separate research has shown that trauma-related shame is linked to posttraumatic stress disorder (PTSD) and, respectively, opioid use. However, no study to date has empirically examined the association between trauma-related shame and NMPOU among individuals with PTSD symptoms. Forty adults with clinical or subclinical PTSD who reported engaging in NMPOU at least one day in the prior month before the study completed 28 days of daily surveys. Trauma-related shame was measured at baseline. NMPOU and underlying motives to engage in NMPOU were assessed once daily via a smartphone app. Twenty-four participants (60 %) reported NMPOU over the 28-day period. After controlling for PTSD symptoms and covariates, mixed models showed that higher trauma-related shame significantly predicted higher risk of daily NMPOU (B = 0.06, SE = 0.03, t = 2.14, p=.03). After controlling for false discovery rates, trauma-related shame also significantly predicted NMPOU due to the following motives (p's < 0.031): to manage depression/sadness, to manage anxiety, to manage other stress/worry, and to get high. Among individuals with PTSD, higher baseline trauma-related shame prospectively and positively predicted greater NMPOU over a four-week daily monitoring period. Findings suggest a need to attend to trauma-related shame and its impact on subsequent motivations to engage in NMPOU. Future research should examine how treatments may effectively target trauma-related shame to reduce NMPOU and more severe PTSD symptoms.

Patient Perspectives on Adapting Collaborative Care for Opioid Use Disorder With Depression and/or Post-traumatic Stress Disorder

BACKGROUND

Individuals with opioid use disorder and cooccurring mental health concerns experience heightened consequences and lower rates of treatment access. Engaging patients as research partners alongside health systems is critical for tailoring care for this population. Collaborative care is promising for the treatment of co-occurring disordersObjectives: We used a community-participatory partnered research1 approach to partner with patients, providers, and clinic administrators to adapt and implement a collaborative care intervention for co-occurring disorders in primary care.

METHODS

We conducted qualitative interviews with patients to assess their feedback on the proposed collaborative care model before intervention implementation. A first round of interviews was conducted to obtain patient feedback on our adaptation ideas (n = 11). The team then incorporated these suggestions, beta-tested the intervention with participants (n = 9), and assessed participant feedback. Data were analyzed using rapid content analysis and then implemented by health systems.

RESULTS

Patient feedback underscored the need for the care coordinator (CC) to be trained in patient engagement and stigma reduction and to provide assistance around socioeconomic barriers and relapse. Patients shared that it was helpful to have the CC address co-occurring disorders, emphasized the need for the CC to be flexible, and expressed that tele-health was acceptable. Patient feedback was integrated in subsequent CC training with health systems.

CONCLUSIONS

The present research demonstrates the feasibility and usefulness of incorporating patient perspectives into treatment design and implementation in health systems using community-participatory partnered research .

Interpersonal Violence and Mental Health, Drug use, and Treatment Utilization among Patients with Co-Occurring Opioid use and Mental Health Disorders

Interpersonal violence is a common type of trauma experienced by people with opioid use disorder (OUD), especially for people with co-occurring OUD and mental illness (COD). However, little is known about demographic and clinical characteristics of individuals with COD who have experienced an interpersonal violence traumatic event compared to those who have experienced a non-violent trauma, and how experiences of interpersonal violence are associated with treatment utilization. Data presented are from a randomized clinical trial testing collaborative care for COD in primary care. Of the 797 patients enrolled in the larger study, 733 (92%) were included in this analysis because they reported a traumatic event. In this sample, 301 (41%) participants experienced a traumatic event involving interpersonal violence. Participants who experienced interpersonal violence were more likely to be younger and female. Among the 301 people who experienced interpersonal violence, 30% experienced child sexual abuse, 23% experienced physical violence, 19% experienced domestic violence, and 28% experienced sexual assault. Those who experienced physical violence were significantly less likely to be female (28.6% vs 74.2% to 88.2% in other groups). Those who reported domestic violence had significantly fewer days of drug use (4.1 days vs 9.0 to 11.5 in the other groups) and lower opioid use severity scores (mean = 13.0 vs 16.6 to 19.5 in the other groups). Multivariable regression results examining the associations between interpersonal violence experiences on treatment utilization revealed no statistically significant differences. Rates of receipt were high for medication for opioid use disorder (∼80%) in this sample while rates of mental health counseling were around 35% and rates of receiving mental health medication around 48%. These findings make an important contribution to understanding the associations between patient characteristics and traumatic experiences, and receipt of treatment for OUD and mental health problems among a sample of patients with COD.

Findings from an Organizational Context Survey to Inform the Implementation of a Collaborative Care Study for Co-occurring Disorders

Primary care is an opportune setting to deliver treatments for co-occurring substance use and mental health disorders; however, treatment delivery can be challenging due multi-level implementation barriers. Documenting organizational context can provide insight into implementation barriers and the adaptation of new processes into usual care workflows. This study surveyed primary care and behavioral health staff from 13 clinics implementing a collaborative care intervention for opioid use disorders co-occurring with PTSD and/or depression as part of a multisite randomized controlled trial. A total of 323 completed an online survey for a 60% response rate. The Consolidated Framework for Implementation Research guided this assessment of multi-level factors that influence implementation. Most areas for improvement focused on inner setting (organizational level) constructs whereas individual-level constructs tended to be strengths. This work addresses a research gap regarding how organizational analyses can be used prior to implementation and provides practical implications for researchers and clinic leaders.

A Harm Reduction Framework for Integrated Treatment of Co-Occurring Opioid Use Disorder and Trauma-Related Disorders

The opioid epidemic has exposed a gulf in mental health research, treatment, and policy: Most patients with comorbid trauma-related disorder (TRD) and opioid use disorder (OUD) (TRD + OUD) remain undiagnosed or unsuccessfully treated for the combination of TRD symptoms and opioid use. TRD treatments tend to be psychotherapies that are not accessible or practical for many individuals with TRD + OUD, due to TRD treatment models not systematically incorporating principles of harm reduction (HR). HR practices prioritize flexibility and unequivocally improve outcomes and save lives in the treatment of OUD. Considering the urgent need to improve TRD + OUD treatment and outcomes, we propose that the OUD and TRD fields can be meaningfully reconciled by integrating HR principles with classic phasic treatment for TRD. Adding a "prestabilization" phase of treatment for TRD - largely analogous to the precontemplation Stage of Change - creates opportunities to advance research, clinical practice, and policies and potentially improve patient outcomes.

Design of CLARO+ (Collaboration Leading to Addiction Treatment and Recovery from Other Stresses, Plus): A randomized trial of collaborative care to decrease overdose and suicide risk among patients with co-occurring disorders

BACKGROUND

The United States is mired in two intertwined epidemics of death from suicide and overdose. Opioid use disorder (OUD) and mental illness contribute to both, and individuals with co-occurring disorders (CODs) are a complex population at high risk. Although universal prevention makes sense from a public health perspective, medical and behavioral health providers often lack the time to proactively address these issues with all patients. In this study, we build upon a parent study called Collaboration Leading to Addiction Treatment and Recovery from Other Stresses (CLARO), a model of collaborative care in which care coordinators deliver preventative measures to high-risk patients and coordinate care with the patients' care team, with the goal of increasing MOUD retention and decreasing risk of suicide and overdose.

METHODS

CLARO+ adds intervention components on overdose prevention, recognition, and response training; lethal means safety counseling; and an effort to mail compassionate messages called Caring Contacts. Both CLARO and CLARO+ have been implemented at 17 clinics in New Mexico and California, and this study seeks to determine the difference in effectiveness between the two versions of the intervention. This paper describes the design protocol for CLARO+.

CONCLUSION

CLARO+ is an innovative approach that aims to supplement existing collaborative care with additional suicide and overdose prevention strategies.

Post-traumatic stress disorder and risky opioid use among persons living with HIV and chronic pain

Persons with HIV (PWH) experience chronic pain and Post-Traumatic Stress Disorder (PTSD) at higher rates than the general population, and more often receive opioid medications to treat chronic pain. A known association exists between PTSD and substance use disorders, but less is known about the relationship between PTSD and risky opioid use among PWH taking prescribed opioid medications. In this observational study of PWH on long-term opioid medications for pain we examined associations between PTSD symptom severity based on the Post Traumatic Stress Disorder Checklist for DSM-5 (PCL-5, response range 0-80) and the following outcomes: 1) risk for opioid misuse (COMM score ≥13); 2) risky alcohol use (AUDIT score ≥8); 3) concurrent benzodiazepine prescription; and 4) morphine equivalent dose. Among 166 patients, 38 (23%) had a PCL-5 score over 38, indicating high PTSD symptom burden. Higher PCL-5 score (per 10 point difference) was associated with increased odds of opioid misuse (aOR 1.55; 95%CI: 1.31-1.83) and risky drinking (aOR: 1.28;1.07-1.52). No significant association was observed between PCL-5 score and benzodiazepine prescriptions or morphine equivalent dose. These findings suggest that when addressing alcohol and opioid use in PWH on long term opioid therapy, attention to PTSD symptoms is especially important given the higher risk for risky alcohol and opioid use among patients with this common comorbid condition.

Posttraumatic stress and pain-related anxiety among trauma-exposed adults with chronic pain in terms of opioid misuse and dependence

Trauma-exposure and posttraumatic stress symptoms increase risk for opioid-related problems in the context of chronic pain. Yet, there has been little exploration of moderators of the posttraumatic stress-opioid misuse association. Pain-related anxiety, defined as worry about pain and the negative consequences of pain, has shown relations to both posttraumatic stress symptoms and opioid misuse, and it may moderate the association between posttraumatic stress symptoms and opioid misuse, as well as dependence. The current study examined the moderating role of pain-related anxiety on the relationship between posttraumatic stress symptoms and opioid misuse and dependence among 292 (71.6 % female, M_age = 38.03 years, SD = 10.93) trauma exposed adults with chronic pain. Results indicated that pain-related anxiety significantly moderated the observed relations, such that compared to those with low pain-related anxiety, the relationship between posttraumatic stress symptoms and opioid misuse and dependence was stronger for those with elevated pain-related anxiety. These results highlight the importance of assessing and targeting pain-related anxiety among this trauma-exposed segment of the chronic pain population with elevated posttraumatic stress symptoms.

Development and feasibility testing of an integrated PTSD and adherence intervention cognitive processing therapy-life steps (CPT-L) to improve HIV outcomes: Trial protocol

Despite high rates of Post-Traumatic Stress Disorder (PTSD) in persons living with HIV (PLWH) and poor HIV-related health outcomes associated with PTSD, an effective evidence-based treatment for PTSD symptoms in PLWH does not exist. Negative reinforcement conceptual models posit that avoidant behavior (hallmark symptom of PTSD) demonstrated by PLWH with co-occurring PTSD can contribute to poor antiretroviral therapy (ART) adherence. However, research evaluating the impact of evidence-based treatment for PTSD among HIV infected populations on HIV outcomes is scarce. The Cognitive Processing Therapy (CPT) protocol is an evidence-based PTSD treatment that may address internalized stigma with targeted modifications and improve ART adherence and subsequent viral suppression through reduction of avoidant coping. This study will be the first pilot open-label randomized control trial (RCT) to test feasibility of an integrated evidence-based PTSD treatment (CPT) with an adherence intervention (Lifesteps) delivered in a Ryan White clinic to improve PTSD symptoms, adherence to ART, and retention in HIV care. Primary aims are to (1) conduct theater testing of the CPT and Lifesteps research protocol and evaluate acceptability (n = 12) and (2) deliver a modified CPT protocol (CPT-Lifesteps, or CPT-L) in 60 PLWH/PTSD exploring impact of CPT-L on PTSD symptoms and HIV outcomes compared to a Lifesteps + Standard of Care condition. This innovative research extends PTSD treatment approaches as a paradigm to reduce barriers to ART adherence. Findings of this innovative study are significant because they support the Undetectable = Untransmittable (U[bond, double bond]U) campaign and can help prevent the transmission of HIV infection through increased viral suppression.

Concurrent and proximal associations among PTSD symptoms, prescription opioid use, and co-use of other substances: Results from a daily monitoring study

OBJECTIVE

Posttraumatic stress disorder (PTSD) and nonmedical prescription opioid use (NMPOU) are linked. Much of the research documenting this association uses cross-sectional or longitudinal designs that describe patterns of use over extended intervals. The present study used a daily monitoring design to examine how daily fluctuations in PTSD symptoms predicted patterns of prescription opioid use (both medical and nonmedical) and co-use of other substances. This approach has distinct advantages for understanding proximal temporal relations between PTSD symptom variation and substance use patterns.

METHOD

Forty adults with clinical or subclinical PTSD and past-month NMPOU completed daily measures of PTSD symptoms, physical pain, prescription opioid use, and other substance use for 28 days using a smartphone application.

RESULTS

Same day co-use of prescription opioids and at least one other substance was common. Higher-than-typical PTSD symptoms on a given day (within-person) was associated with an increased likelihood of reporting NMPOU (overall and with co-use of one or more additional substances) on the same day. This association was specific to PTSD alterations in arousal and reactivity symptoms (Criteria E). Neither total PTSD symptoms nor individual PTSD symptom clusters prospectively predicted next-day prescription opioid use (overall or with co-use). Use of prescription opioids also did not predict next-day PTSD symptom severity.

CONCLUSION

This is the first study to demonstrate positive associations between day-to-day fluctuations in PTSD symptoms and NMPOU. Results from the current study also highlight the importance of examining polysubstance use patterns among individuals with PTSD who use prescription opioids.

Sleep disturbance as a therapeutic target to improve opioid use disorder treatment

Sleep health is an important factor across several physical and mental health disorders, and a growing scientific consensus has identified sleep as a critical component of opioid use disorder (OUD), both in the active disease state and during OUD recovery. The goal of this narrative review is to collate the literature on sleep, opioid use, and OUD as a means of identifying therapeutic targets to improve OUD treatment outcomes. Sleep disturbance is common and often severe in persons with OUD, especially during opioid withdrawal, but also in persons on opioid maintenance therapies. There is ample evidence that sleep disturbances including reduced total sleep time, disrupted sleep continuity, and poor sleep quality often accompany negative OUD treatment outcomes. Sleep disturbances are bidirectionally associated with several other factors related to negative treatment outcomes, including chronic stress, stress reactivity, low positive affect, high negative affect, chronic pain, and drug craving. This constellation of outcome variables represents a more comprehensive appraisal of the quality of life and quality of recovery than is typically assessed in OUD clinical trials. To date, there are very few clinical trials or experimental studies aimed at improving sleep health in OUD patients, either as a means of improving stress, affect, and craving outcomes, or as a potential mechanistic target to reduce opioid withdrawal and drug use behaviors. As such, the direct impact of sleep improvement in OUD patients is largely unknown, yet mechanistic and clinical research suggests that therapeutic interventions that target sleep are a promising avenue to improve OUD treatment.

Suicidality as a Predictor of Overdose among Patients with Substance Use Disorders

Increasing rates of overdose and overdose deaths are a significant public health problem. Research has examined co-occurring mental health conditions, including suicidality, as a risk factor for intentional and unintentional overdose among individuals with substance use disorder (SUD). However, this research has been limited to single site studies of self-reported outcomes. The current research evaluated suicidality as a predictor of overdose events in 2541 participants who use substances enrolled across eight multi-site clinical trials completed within the National Drug Abuse Treatment Clinical Trials Network between 2012 to 2021. The trials assessed baseline suicidality with the Concise Health Risk Tracking Self-Report (CHRT-SR). Overdose events were determined by reports of adverse events, cause of death, or hospitalization due to substance overdose, and verified through a rigorous adjudication process. Multivariate logistic regression was performed to assess continuous CHRT-SR score as a predictor of overdose, controlling for covariates. CHRT-SR score was associated with overdose events (p = 0.03) during the trial; the likelihood of overdose increased as continuous CHRT score increased (OR 1.02). Participants with lifetime heroin use were more likely to overdose (OR 3.08). Response to the marked rise in overdose deaths should integrate suicide risk reduction as part of prevention strategies.

Collaboration Leading to Addiction Treatment and Recovery from Other Stresses (CLARO): process of adapting collaborative care for co-occurring opioid use and mental disorders

Background

Opioid use disorders (OUD), co-occurring with either depression and/or PTSD, are prevalent, burdensome, and often receive little or low-quality care. Collaborative care is a service delivery intervention that uses a team-based model to improve treatment access, quality, and outcomes in primary care patients, but has not been evaluated for co-occurring OUD and mental health disorders. To address this treatment and quality gap, we adapted collaborative care for co-occurring OUD and mental health disorders.

Methods

Our adapted model is called Collaboration Leading to Addiction Treatment and Recovery from Other Stresses (CLARO). We used the five-step Map of Adaptation Process (McKleroy in AIDS Educ Prev 18:59–73, 2006) to develop the model. For each step, our stakeholder team of research and clinical experts, primary care partners, and patients provided input into adaptation processes (e.g., adaptation team meetings, clinic partner feedback, patient interviews and beta-testing). To document each adaptation and our decision-making process, we used the Framework for Reporting Adaptations and Modifications-Enhanced (Wiltsey Stirman in Implement Sci 14:1–10, 2019).

Results

We documented 12 planned fidelity-consistent adaptations to collaborative care, including a mix of content, context, and training/evaluation modifications intended to improve fit with the patient population (co-occurring disorders) or the New Mexico setting (low-resource clinics in health professional shortage areas). Examples of documented adaptations include use of community health workers as care coordinators; an expanded consultant team to support task-shifting to community health workers; modified training protocols for Problem-Solving Therapy and Written Exposure Therapy to incorporate examples of treating patients for depression or PTSD with co-occurring OUD; and having care coordinators screen for patients’ social needs.

Conclusions

We completed the first three steps of the Map of Adaptation Process, resulting in a variety of adaptations that we believe will make collaborative care more acceptable and feasible in treating co-occurring OUD and mental health disorders. Future steps include evaluating the effectiveness of CLARO and documenting reactive and/or planned adaptations to the model that occur during its implementation and delivery.

Opioid use as a proximal risk factor for suicidal behavior in young adults

INTRODUCTION

There is a concomitant rise in suicide rates with the prevalence of opioids involved in overdose deaths, especially among adolescents and young adults. However, there are limited studies on whether opioid use prospectively predicts suicidal behavior in youth.

METHODS

Our sample included 183 psychiatric patients (18-30 years) admitted for a suicide attempt (SA), have current suicidal ideation (SI), and psychiatric controls without ideation or attempt (PC). Suicidal behavior was assessed using the Columbia Suicide Severity Rating Scale. We also recruited a healthy control group (HC; n = 40). Patients and controls were followed over a year. ANOVA, regression, and cox regression were used.

RESULTS

Suicide attempt (β = 0.87, CI [0.1-1.6], p = 0.02) and SI [(β = 0.75, CI [0.03-1.5], p = 0.04) were significantly more likely than HCs to have used opioids in the past year at baseline. Opioid use was associated with increased anxiety symptoms (β = 0.75, CI [0.001-1.5], p = 0.05), PTSD symptoms (β = 3.90, CI [1.1-6.7], p = 0.01), and aggression (β = 0.02, CI [0.01-0.04], p = 0.02). Opioid use in the month prior to hospitalization predicted SA at 6 months (OR = 1.87, CI [1.06-3.31], p = 0.032).

CONCLUSIONS

Opioid use is a proximal predictor for SA. These findings may help clinicians better identify patients at risk for suicidal behavior, allowing for more personalized treatment approaches.

Exploring Differences in Baseline Characteristics among Adults Entering Integrated Residential Treatment for Co-occurring Disorders in 2013 and 2017

Little is known about patients' addiction severity, substance use, or mental health symptoms upon entering integrated treatment. This is the first study to compare baseline characteristics among cohorts of patients with co-occurring disorders entering a private integrated residential treatment program in 2013 and 2017; a period when severe and persistent mental illness diagnoses, mental health service use, and overdose deaths increased. Our sample includes 3400 patients entering private, integrated residential treatment during 2013 (n = 1535) and 2017 (n = 1865). Trained staff completed admission interviews of all participants that included the Addiction Severity Index (ASI), a semi-structured interview to evaluate the past 30-day functioning of the following domains: medical, employment, alcohol, drug, legal, family or social support systems, and psychiatric. We used a p-value of 0.05 to assess significance. With the exception of the drug composite score, the 2017 cohort scored higher than the 2013 cohort on all other composite scores. Compared to the 2013 cohort, the 2017 cohort reported more days using alcohol, cocaine, amphetamines, and engaging in polysubstance use. Conversely, the 2017 cohort reported fewer days using other prescription opioids and sedatives than the 2013 cohort. After controlling for age, the 2017 cohort reported more days of marijuana use than the 2013 cohort. The 2017 cohort reported higher rates of the following symptoms: depression, anxiety, hallucinations, and suicidal ideation. Findings underscore differences among integrated treatment patient cohorts for baseline addiction severity, substance use, or mental health symptoms.

Complex Interactions Between Sex and Stress on Heroin Seeking

Rationale: Stress plays a dual role in substance use disorders as a precursor to drug intake and a relapse precipitant. With heroin use at epidemic proportions in the United States, understanding interactions between stress disorders and opioid use disorder is vital and will aid in treatment of these frequently comorbid conditions. Objectives: Here, we combine assays of stress and contingent heroin self-administration (SA) to study behavioral adaptations in response to stress and heroin associated cues in male and female rats. Methods: Rats underwent acute restraint stress paired with an odor stimulus and heroin SA for subsequent analysis of stress and heroin cue reactivity. Lofexidine was administered during heroin SA and reinstatement testing to evaluate its therapeutic potential. Rats also underwent tests on the elevated plus maze, locomotor activity in a novel environment, and object recognition memory following stress and/or heroin. Results: A history of stress and heroin resulted in disrupted behavior on multiple levels. Stress rats avoided the stress conditioned stimulus and reinstated heroin seeking in response to it, with males reinstating to a greater extent than females. Lofexidine decreased heroin intake, reinstatement, and motor activity. Previous heroin exposure increased time spent in the closed arms of an elevated plus maze, activity in a round novel field, and resulted in object recognition memory deficits. Discussion: These studies report that a history of stress and heroin results in maladaptive coping strategies and suggests a need for future studies seeking to understand circuits recruited in this pathology and eventually help develop therapeutic approaches.

Posttraumatic stress disorder in individuals seeking treatment for opioid use disorder in Vermont

Posttraumatic stress disorder (PTSD) and opioid use disorder (OUD) may be associated with poor outcomes in rural areas where access to mental health services and opioid agonist treatment (OAT) is limited. This study examined the characteristics associated with a history of PTSD among a sample of individuals seeking buprenorphine treatment for OUD in Vermont, the second-most rural state in the US. Participants were 89 adults with OUD who participated in one of two ongoing randomized clinical trials examining the efficacy of an interim buprenorphine dosing protocol for reducing illicit opioid use during waitlist delays to OAT. Thirty-one percent of participants reported a history of PTSD. Those who did (PTSD+; n = 28) and did not (PTSD-; n = 61) report a history of PTSD were similar on sociodemographic and drug use characteristics. However, the PTSD+ group was less likely to have received prior OUD treatment compared to the PTSD- group (p = .02) despite being more likely to have a primary care physician (p = .009) and medical insurance (p = .002). PTSD+ individuals also reported greater mental health service utilization, more severe psychiatric, medical and drug use consequences, and greater pain severity and interference vs. PTSD- individuals (ps < 0.05). These findings indicate that a history of PTSD is prevalent and associated with worse outcomes among individuals seeking treatment for OUD in Vermont. Dissemination of screening measures and targeted interventions may help address the psychiatric and medical needs of rural individuals with OUD and a history of PTSD.

Treatment outcomes in individuals diagnosed with comorbid opioid use disorder and Posttraumatic stress disorder: A review

OBJECTIVES

Opioid use disorder (OUD) is a public health emergency. Evidence suggests that posttraumatic stress disorder (PTSD) is common among individuals with OUD; however, few studies evaluate whether concurrent diagnoses affect treatment outcomes. This review examines the impact of concurrent diagnoses of OUD and PTSD on treatment outcomes.

METHODS

A search was performed using articles identified through June 30, 2020 in PubMed, PsycINFO, and EMBASE. Included peer-reviewed articles evaluated individuals with OUD and a PTSD diagnosis via standardized assessment and/or medical record diagnoses, and reported relationships between diagnosis and treatment outcomes and/or other psychiatric conditions.

RESULTS

Out of 412 articles, 17 studies met inclusion criteria for this review (from 13 databases). Articles included had a total of n = 2190 with OUD, with n = 79 non-OUD comparison participants. Studies examining individuals with OUD revealed comorbid PTSD was associated with more severe addiction, higher rates of depression, attempted suicide, and psychosocial problems.

CONCLUSIONS

Among individuals with OUD, presence of PTSD is associated with multiple mental health problems. The impact of PTSD on drug use is inconclusive. Although only 5 studies examined psychosocial PTSD treatment, all found PTSD-focused treatment to be effective for those with comorbid OUD. Overall, results suggest the need to better identify PTSD among those with OUD, and to develop and evaluate interventions that are brief, integrative, and easy to implement in clinical settings.

Prescription Opioid Misuse and Sports-Related Concussion Among High School Students in the United States

STUDY OBJECTIVE

Concussion is highly prevalent in adolescents and associated with a higher risk of substance use. With the rising use of opioids among adolescents, one form of substance use of concern is the misuse of prescription opioids. This study aimed to examine the association between a history of sports-related concussion in the past year and current prescription opioid misuse among high school students in the United States.

SETTING

Secondary data analysis from the 2019 Youth Risk Behavior Survey.

PARTICIPANTS

Nationally representative sample of high school students (n = 7314).

DESIGN

Cross-sectional study.

MAIN MEASURES

Participants were asked whether they experienced any concussions related to sports or being physically active during the past 12 months and whether they had any prescription opioid misuse within the past 30 days.

RESULTS

Among this cohort, 14.0% reported sustaining a concussion in the past 12 months and 6% reported current prescription opioid misuse. The prevalence of prescription opioid misuse was higher among those with a history of concussion (9.9%) than among those without concussion (5.5%, P = .002). Controlling for covariates (sex, race/ethnicity, other substance use, depressive symptoms), the odds of prescription opioid misuse was 1.5 times higher for adolescents with concussion than those without (adjusted odds ratios [aOR] = 1.5; 95% CI, 1.0-2.3; P = .029).

CONCLUSION

Concussion was associated with prescription opioid misuse among the US youth, even after accounting for depressive symptoms and other substance use. Longitudinal studies are needed to test causal relationships and understand biobehavioral mechanisms that underlie associations between concussion and opioid misuse in adolescents.

High-risk and Long-term Opioid Prescribing to Military Spouses in the Millennium Cohort Family Study

INTRODUCTION

The use and misuse of opioids by active service members has been examined in several studies, but little is known about their spouses' opioid use. This study estimates the number of military spouses who received high-risk or long-term opioid prescriptions between 2010 and 2014, and addresses how the Military Health System can help prevent risky prescribing in order to improve military force readiness.

MATERIALS AND METHODS

This study used data from the Millennium Cohort Family Study, a nationwide survey of 9,872 spouses of service members with 2 to 5 years of military service, augmented with information from the military's Pharmacy Data Transaction Service about prescriptions for controlled drugs dispensed to these service members' spouses. Our objectives were to estimate the prevalence of opioid prescribing indicative of long-term use (≥60 day supply or at least one extended-release opioid prescription in any 3-month period) and, separately, high-risk use (daily dosage of ≥90 morphine mg equivalent or total dosage of ≥8,190 morphine mg equivalent, or prescriptions from more than three pharmacies, or concurrent prescriptions). For each of these dependent variables, we conducted bivariate analyses and multiple logistic regression models using information about spouses' physical health, sociodemographic characteristics, substance use behaviors, perceived social support, and stresses associated with military stress, among others. Informed consent, including consent to link survey responses to medical and personnel records, was obtained from all participants. The Naval Health Research Center's Institutional Review Board and the Office of Management and Budget approved the study.

RESULTS

Spouses were predominantly female (86%), had not served in the military themselves (79%), and were spouses of enlisted (91%) active duty (86%) service members. Almost half (47.6%) of spouses obtained at least one opioid prescription during the 2-year observation window, and 8.5% had received opioid prescriptions that posed risk to their health. About 7% met the criteria for receipt of high-risk opioid prescriptions, 3% obtained opioids from three or more pharmacies during a 3-month period, and 4% of spouses who received any opioids received both long-term and high-risk prescriptions. Adverse childhood experiences, physical pain, and lack of social support were associated with increased odds of obtaining high-risk opioid prescriptions.

CONCLUSIONS

Approximately 48% of military spouses had used Military Health System insurance to fill at least one opioid prescription during the 2-year observation period. The Department of Defense has taken measures to minimize high-risk opioid prescribing, including passing prescribing guidelines in 2017, establishing the controlled drug management analysis reporting tool, establishing a pain management education and training program, and more. These efforts should continue to expand as reducing the numbers of service members and spouses at risk for adverse events may be effective in reducing opioid misuse and improve the overall health and safety of military spouses and thus, the readiness of the U.S. Armed Forces.

Design of CLARO (Collaboration Leading to Addiction Treatment and Recovery from other Stresses): A randomized trial of collaborative care for opioid use disorder and co-occurring depression and/or posttraumatic stress disorder

INTRODUCTION

Opioid use disorder (OUD) co-occurring with depression and/or posttraumatic stress disorder (PTSD) is common and, if untreated, may lead to devastating consequences. Despite the availability of evidence-based treatments for these disorders, receipt of treatment is low. Even when treatment is provided, quality is variable. Primary care is an important and underutilized setting for treating co-occurring disorders (COD) because OUD, depression and PTSD are frequently co-morbid with medical conditions and most people visit a primary care provider at least once a year. With rising rates of OUD and opioid-related fatalities, this is a critical treatment and quality gap in a vulnerable and stigmatized population.

METHODS

CLARO (Collaboration Leading to Addiction Treatment and Recovery from Other Stresses) is a multi-site, randomized pragmatic trial of collaborative care (CC) for co-occurring disorders in 13 rural and urban primary care clinics in New Mexico to improve care for patients with OUD and co-occurring depression and/or PTSD. CC, a service delivery approach that uses multi-faceted interventions, has not been tested with COD. We will enroll and randomize 900 patients to either CC adapted for COD (CC-COD) or enhanced usual care (EUC) and will collect patient data at baseline, 3-, and 6-month follow-up. Our primary outcomes are medications for OUD (MOUD) access, MOUD continuity of care, depression symptoms, and PTSD symptoms.

DISCUSSION

Although CC is effective for improving outcomes in primary care among patients with mental health conditions, it has not been tested for COD. This article describes the CLARO CC-COD intervention and clinical trial.

The relationship between dissociative symptoms and the medications used in the treatment of opioid use disorder

Opioid use disorder has long been associated with psychiatric symptoms, including dissociative experiences. Medications used to treat opioid use disorder can potentially impact dissociative symptoms, but the existing literature has not explored this. We examined the relationship between dissociative symptoms and opioid use disorder using the Dissociative Experiences Scale (DES). We studied subjects who were taking prescribed methadone, buprenorphine, or naltrexone for opioid use disorder. We gave the DES, the Patient Health Questionairre-9 (PHQ-9), and the PTSD Checklist for DSM-5 (PCL-5) with Criterion A to subjects in three substance use treatment facilities in Ohio. We conducted Analysis of Variance (ANOVA) and Spearman's Rank Correlations to examine associations between the variables and outcomes. We developed three separate multiple linear regression models. We included 116 participants in our exploratory and naturalistic study. The majority of participants were female (51.7%), white (89.5%), ≤ 40 years of age (64.7%), and taking buprenorphine (55%). The average DES score was 16.1 (standard deviation = 14.9) and we considered 80.9% to have low dissociation (score < 30). Approximately 55% (n = 64) of participants were taking prescribed buprenorphine. Approximately 27% (n = 32) were taking prescribed methadone and approximately 18% (n = 21) were taking prescribed naltrexone (oral or extended release). There was a significant association between opioid medication type and log dissociative symptoms (p = .01). Participants taking prescribed buprenorphine had higher mean log dissociation symptom scores (2.7) compared to those taking prescribed methadone (2.2) and prescribed naltrexone (2.1). Log dissociation symptom scores were significantly associated with last use of any opiates (rs = -0.21; p = .02) and time on medication (rs = -0.228; p = .01). Compared to those taking buprenorphine, those taking both methadone (β = -0.26; p = .01) and naltrexone (β = -0.27; p = .006) had significantly lower dissociation scores, controlling for the other variables in the model. Dissociation scores were positively correlated with depression scores (r = 0.45; p < .0001) and with PCL-5 scores (r = 0.51; p < .0001). Our study highlights the importance of diagnosing and monitoring dissociative symptoms in individuals who are taking prescribed medications for opioid use disorder, especially since dissociative symptoms can interfere with substance use treatment.

Misuse of Prescription Pain Relievers, Stimulants, Tranquilizers, and Sedatives Among U.S. Older Adults Aged ≥50 Years

INTRODUCTION

Misuse of prescription medications has led to higher mortality and morbidity in the U.S. This study investigates medical and nonmedical use of prescription medications (prescription pain relievers, stimulants, prescription tranquilizers, and sedatives) among adults aged ≥50 years.

METHODS

Data were from the 2015-2017 National Survey of Drug Use and Health. For each prescription medication, medical and nonmedical use were mutually exclusive (prescription pain relievers, stimulants, tranquilizers, and sedatives). Nonmedical use (misuse) was defined as the use of any prescription medications in greater amounts, frequency, or duration than prescribed or the use of medications without a prescription of the individual's own. Descriptive analysis was performed to assess prescription medication use and misuse among adults aged ≥50 years (pooled N=26,322). Correlates of misuse were assessed within multivariable logistic regression analyses at p<0.05. All analyses were conducted in 2019.

RESULTS

In the past 12 months, 46.7% (51.7 million) of adults reported using any prescription medication, of which 7.7% (4.0 million) reported misuse. The proportion of past 12-month users reporting misuse was 5.4% for sedatives, 6.4% for prescription pain relievers, 6.5% for prescription tranquilizers, and 8.1% for stimulants. Overall, 16.2% (17.9 million) reported using 2 or more prescription medications within the past 12 months. Multiple prescription medication use was associated with female sex; White race; younger age; and use of nonprescription substances, including alcohol, tobacco, marijuana, and heroin.

CONCLUSIONS

It is important to monitor medication misuse behaviors among older adults who may be living with several chronic conditions requiring pain management. The strong associations with serious psychological distress underscore the need for increased access to mental health services among this key population.

Dorsal hippocampal interleukin-1 signaling mediates heroin withdrawal-enhanced fear learning

Converging evidence suggests opioid abuse can increase the incidence and severity of post-traumatic stress disorder (PTSD) in clinical populations. Interestingly, opioid withdrawal alone can produce symptoms similar to those of PTSD. Despite this association, the neural mechanisms underlying the relationship of opioid abuse, withdrawal, and PTSD is poorly understood. Our laboratory has investigated the neurobiological underpinnings of stress-enhanced fear learning (SEFL), an animal model of PTSD-like symptoms. We have previously shown that, in SEFL, a severe footshock induces an increase in dorsal hippocampal (DH) interleukin-1β (IL-1β), and subsequent fear learning is blocked by DH IL-1 receptor antagonism (IL-1RA). Given that opioids and stress engage similar neuroimmune mechanisms, the present experiments investigate whether the same mechanisms drive heroin withdrawal to induce a PTSD-like phenotype. First, we tested the effect of a chronic escalating heroin dose and withdrawal regimen on fear learning and found it produces enhanced future fear learning. Heroin withdrawal also induces a time-dependent, region-specific increase in IL-1β and glial fibrillary acidic protein (GFAP) immunoreactivity within the dentate gyrus of the DH. IL-1β was significantly colocalized with GFAP, indicating astrocytes may be involved in increased IL-1β. Moreover, intra-DH infusions of IL-1RA 0, 24, and 48 h into heroin withdrawal prevents the development of enhanced fear learning but does not alter withdrawal-induced weight loss. Collectively, our data suggests heroin withdrawal is sufficient to produce enhanced fear learning, astrocytes may play a role in heroin withdrawal-induced IL-1β, and DH IL-1 signaling during withdrawal mediates the development of heroin withdrawal-enhanced fear learning.

The role of catecholamines in modulating responses to stress: Sex-specific patterns, implications, and therapeutic potential for post-traumatic stress disorder and opiate withdrawal

Emotional arousal is one of several factors that determine the strength of a memory and how efficiently it may be retrieved. The systems at play are multifaceted; on one hand, the dopaminergic mesocorticolimbic system evaluates the rewarding or reinforcing potential of a stimulus, while on the other, the noradrenergic stress response system evaluates the risk of threat, commanding attention, and engaging emotional and physical behavioral responses. Sex-specific patterns in the anatomy and function of the arousal system suggest that sexually divergent therapeutic approaches may be advantageous for neurological disorders involving arousal, learning, and memory. From the lens of the triple network model of psychopathology, we argue that post-traumatic stress disorder and opiate substance use disorder arise from maladaptive learning responses that are perpetuated by hyperarousal of the salience network. We present evidence that catecholamine-modulated learning and stress-responsive circuitry exerts substantial influence over the salience network and its dysfunction in stress-related psychiatric disorders, and between the sexes. We discuss the therapeutic potential of targeting the endogenous cannabinoid system; a ubiquitous neuromodulator that influences learning, memory, and responsivity to stress by influencing catecholamine, excitatory, and inhibitory synaptic transmission. Relevant preclinical data in male and female rodents are integrated with clinical data in men and women in an effort to understand how ideal treatment modalities between the sexes may be different.

Opioid use disorder

Opioid use disorder (OUD) is a chronic relapsing disorder that, whilst initially driven by activation of brain reward neurocircuits, increasingly engages anti-reward neurocircuits that drive adverse emotional states and relapse. However, successful recovery is possible with appropriate treatment, although with a persisting propensity to relapse. The individual and public health burdens of OUD are immense; 26.8 million people were estimated to be living with OUD globally in 2016, with >100,000 opioid overdose deaths annually, including >47,000 in the USA in 2017. Well-conducted trials have demonstrated that long-term opioid agonist therapy with methadone and buprenorphine have great efficacy for OUD treatment and can save lives. New forms of the opioid receptor antagonist naltrexone are also being studied. Some frequently used approaches have less scientifically robust evidence but are nevertheless considered important, including community preventive strategies, harm reduction interventions to reduce adverse sequelae from ongoing use and mutual aid groups. Other commonly used approaches, such as detoxification alone, lack scientific evidence. Delivery of effective prevention and treatment responses is often complicated by coexisting comorbidities and inadequate support, as well as by conflicting public and political opinions. Science has a crucial role to play in informing public attitudes and developing fuller evidence to understand OUD and its associated harms, as well as in obtaining the evidence today that will improve the prevention and treatment interventions of tomorrow.

Age Differences in Non-Medical Prescription Opioid Use and Psychological Distress

Background/Purpose: Prescription opioid use has been recognized as an epidemic in the United States and globally. More research is needed to understand the association of opioids and mental health for older adults. This study examined age differences in the association of non-medical prescription opioid use (NMPOU) and psychological distress, with a focus on older adult populations. Methods: This study used the 2016 National Survey on Drug Use and Health (NSDUH), and included 37,842 adults aged 18 and older. Weighted multiple regression and logistic regression analyses were used to examine the association of NMPOU and psychological distress, measured by the Kessler Psychological Distress Scale (K6). Results: NMPOU was associated with higher psychological distress (b = 0.48, SE = 0.16, p < .01). For those 50 and older, NMPOU was associated with 224% increased odds of meeting the clinical threshold for having a serious mental illness (SMI; OR = 2.24, p < .01, 95% CI: 1.23, 4.09). Conclusions: Although the prevalence of NMPOU and psychological distress trended downward throughout the lifespan, the association of NMPOU on SMI was highest among the youngest and oldest adults. These findings highlight the need for services and supports that are tailored for older adult populations. Future research is needed to investigate vulnerabilities from life stage stressors specific to older adults, which may account for the disproportionate odds of opioid use on mental health pathology. Interprofessional collaboration is needed among geriatric professionals to provide effective mental health treatment for this at-risk population.

Small area estimation and hotspot identification of opioid use disorder among military veterans living in the Southern United States

BACKGROUND

The purpose of this study was to estimate opioid use disorder prevalence rates at the county level among veterans in Alabama and to determine hotspots of said rates. Methods: By combining data from the National Survey on Drug Use and Health and the American Community Survey, we developed a mixed-effects generalized linear model of opioid use disorder and modeled probabilities onto veteran-specific population counts at the county level in Alabama. Results: The average model-based estimate for opioid use disorder prevalence among veterans in Alabama from 2015 to 2017 was 0.79% (SD = 0.16), with a minimum of 0.52% (i.e., Lowndes county, Alabama) and a maximum of 1.10% (Dale county, Alabama). Hotspot analysis revealed a significant cluster of "high-high" veteran opioid use disorder prevalence in neighboring Marion, Winston, and Cullman counties. Conclusions: The application of the statistical technique presented in this study can provide feasible, cost-effective, and practical county-level prevalence estimates of veteran-specific opioid use disorder and should be widely applied by states and counties so that they can more accurately and efficiently allocate resources to caring for veterans with an opioid use disorder.

Psychiatric comorbidity and co-occurring opioid misuse: Depression mediates the relationship between post-traumatic stress disorder and opioid misuse in community pharmacy settings

AbstractsBackground: Individuals who misuse opioids frequently have comorbid psychiatric issues, including post-traumatic stress disorder (PTSD) and depression. However, little is known about the mechanisms by which these disorders are associated with opioid misuse and specifically in community pharmacy settings. The current study examined whether depression mediated the relationship between PTSD and opioid misuse in patients filling opioid prescriptions. Methods: We administered a health survey in four community pharmacies among patients filling opioid medications in southwestern Pennsylvania. Univariate statistics were used to assess relationships among demographic and clinical characteristics of PTSD, depression, and opioid misuse behaviors. We then examined whether depression mediated the relationship between PTSD and opioid misuse using ordinary least squares path analysis with bootstrapping. Results: A total of 333 participants completed the health survey. Opioid misuse was reported among 15.9% of all participants, 33.3% among those with a positive PTSD screen, and 29.3% of those who screened positive for depression. Depression significantly mediated the relationship between PTSD and opioid misuse. Specifically, there was a statistically significant indirect effect (ab) of PTSD on opioid misuse through a pathway mediated by depression (ab = .06, SE_ab = .02, 95% CI = .02-.10). The direct effect (c') of PTSD on opioid misuse was also significant (c' = .12, SE_c' = .05, P = .01, 95% CI = .03-.22), suggesting partial mediation. Conclusions: Results suggest an indirect pathway by which clinical intervention may help ameliorate outcomes in patients with PTSD. Further, there is an increased need for screening, assessment, and intervention protocols for this patient population in which community pharmacy is a novel setting to expand future efforts within the patient population.

Risk Assessment and Monitoring of Patients with Cancer Receiving Opioid Therapy

To provide safe and effective management of cancer pain, a thorough risk assessment is needed when conducting a comprehensive pain evaluation. This information provides the basis for decisions about appropriate pain relief interventions and for measures that can be taken to mitigate the potential for misuse of opioids and other substances.

The primary objective of this article is to assist oncologists and advanced practice prescribers to safely and effectively minimize risk when providing opioids for cancer pain relief. The majority of people with cancer are unlikely to misuse or divert opioid medications, yet the prescriber is often unaware of those who are at risk for these behaviors. To provide skillful pain management to each patient in the oncology setting, while limiting harm to the community, all prescribers must consider the potential for risk of misuse, addiction, or diversion. To minimize this risk to the greatest degree possible, it is imperative to include a thorough risk assessment when conducting a comprehensive pain evaluation. This information is then used to triage pain relief interventions based upon the degree of risk, including whether or not to incorporate opioids into the plan of care. Risk mitigation strategies, incorporating universal precautions, are implemented to assess, monitor, and reduce the potential for opioid misuse. Universal precautions include strategies such as the use of urine toxicology, state prescription drug monitoring programs, and agreements. Ongoing monitoring is conducted with the goal being to identify aberrant behaviors early so that they can be addressed and managed appropriately. Referral to addiction specialists may be warranted when substance use disorder precludes safe use of opioids.

Implications for Practice.

Throughout the trajectory of cancer care, opioid use is often indicated, and, in fact, it may be unethical to limit or prohibit the use of opioids when pain is severe. Oncologists face the significant challenge of providing cancer pain control that is safe and effective, while limiting individual risk for abuse or overdose and keeping the community free of diverted substances. Most oncology providers report inadequate training in chronic pain principles and in managing addiction. Risk assessment and mitigation measures can be incorporated within oncology care to enhance effective pain management while reducing the potential for harm.

Understanding and treating opioid use disorders in lesbian, gay, bisexual, transgender, and queer populations

Although little is known about the specific burden of the opioid epidemic on lesbian, gay, bisexual, transgender, and queer (LGBTQ) populations, there is evidence to suggest that opioid use disorders are disproportionately prevalent in the LGBTQ community. In this commentary, we present an overview of the current state of evidence on opioid use and misuse among LGBTQ-identified people in the United States and suggest ways to adapt behavioral health interventions to the specific needs of this population. Programs that integrate behavioral health with primary care, address minority stress, and use a trauma-informed approach have the most potential to produce effective, long-term benefits for LGBTQ-identified people with opioid use disorders.

A comparison of 2013 and 2017 baseline characteristics among treatment-seeking patients who used opioids with co-occurring disorders

The opioid epidemic is a public health crisis that has captured the attention of the media and political leaders, but how much do we know about its implications for substance use disorder treatment providers? This study is the first to investigate the differing baseline characteristics among patients with co-occurring disorders who used opioids and entered residential treatment in 2013 and 2017. Our sample consisted of 1413 unique adults who reported using opioids upon admission to integrated residential treatment for co-occurring substance use and mental health disorders during 2013 (n = 718) and 2017 (n = 695). Opioid use was defined as self-reported use of heroin or illicit use of prescription opioids, including methadone, during the month prior to admission into the treatment program. All study participants completed an admission interview that included the Addiction Severity Index (ASI). The 2017 cohort demonstrated higher severity than the 2013 cohort on the employment, psychiatric, and alcohol and drug ASI composite scores. A comparison of days per month that the cohorts used various substances also reveals this trend, with the following comparisons listing the 2017 cohort data first, and the 2013 cohort data second: (1) alcohol (8.6 days vs. 7.0 days); (2) cocaine (4.1 days vs. 2.2 days); (3) amphetamines (6.2 days vs. 3.6 days); and (4) polysubstance use in one day (16.6 days vs. 11.6 days). The 2017 cohort was also intoxicated from alcohol more days per month (7.2 days vs. 5.1 days). However, the 2017 cohort reported fewer days using prescription opioids (9.9 days vs. 12.4 days). A higher proportion of the 2017 cohort reported (1) depression (74% vs. 68%); (2) anxiety (88% vs. 84%); (3) hallucinations (14% vs 8%); and (4) and suicidal ideation (22% vs. 17%).

Sex differences in morphine-induced trafficking of mu-opioid and corticotropin-releasing factor receptors in locus coeruleus neurons

The locus coeruleus (LC)-norepinephrine (NE) system is a key nucleus in which endogenous opioid and stress systems intersect to regulate the stress response. LC neurons of male rats become sensitized to stress following chronic morphine administration. Whether sex dictates this pattern of opioid-induced plasticity has not been demonstrated. Delineating the neurobiological adaptations produced by chronic opioids will enhance our understanding of stress vulnerability in opioid-dependent individuals, and may reveal how stress negatively impacts addiction recovery. In the present study, the effect of chronic morphine on the subcellular distribution of mu-opioid (MOR) and CRF receptors (CRFR) was investigated in the LC of male and female rats using immunoelectron microscopy. Results showed that placebo-treated females exhibited higher MOR and CRFR cytoplasmic distribution ratio when compared to placebo-treated males. Chronic morphine exposure induced a shift in the distribution of MOR immunogold-silver particles from the plasma membrane to the cytoplasm selectively in male LC neurons. Interestingly, chronic morphine exposure induced CRFR recruitment to the plasma membrane of both male and female LC neurons. These findings provide a potential mechanism by which chronic opioid administration increases stress vulnerability in males and females via an increase in surface availability of CRFR in LC neurons. However, our results also support the notion that cellular adaptations to chronic opioids differ across the sexes as redistribution of MOR following morphine exposure was only observed in male LC neurons.

Importance of Behavioral Therapy in Patients Hospitalized for Post-Traumatic Stress Disorder (PTSD) with Opioid Use Disorder

Objective: To analyze differences in demographic pattern and hospitalization outcomes in post-traumatic stress disorder (PTSD) with opioid use disorder (OUD) patients managed with versus without behavioral therapy (BT). Methods: We conducted case-control study using Nationwide Inpatient Sample and identified PTSD and OUD using ICD–9–CM codes. Linear regression model was used to evaluate impact of BT on inpatient stay and cost. Results: We analyzed 1531 inpatient admissions and 786 patients received BT. Females had higher odds of receiving BT during inpatient management for PTSD with OUD (OR 1.210; 95% CI 1.020–1.436). About 63.1% patients receiving BT were benefited by Medicaid. Patients receiving BT had an increase in hospital stay by 1.27 days (P = 0.085) and hospitalization cost by $4734 (P = 0.018). There were no transfers to short term hospitals and lower transfers to skilled nursing facility (3.8% vs. 10.1%) in patients receiving BT. Conclusion: This study aims to reinforce combination management with psychotropic medications and BT in PTSD patients with comorbid OUD during hospitalization as it significantly decreases adverse disposition of the patient and thereby improves the quality of life post-treatment.

Adults with Comorbid Posttraumatic Stress Disorder, Alcohol Use Disorder, and Opioid Use Disorder: The Effectiveness of Modified Prolonged Exposure

Opioid use disorders (OUDs) are a growing problem in the United States. When OUDs co-occur with problematic drinking and posttraumatic stress disorder (PTSD), negative drug-related mental and physical health outcomes may be exacerbated. Thus, it is important to establish whether PTSD treatments with established efficacy for dually diagnosed individuals also demonstrate efficacy in individuals who engage in problematic drinking and concurrent opioid misuse. Adults who met DSM-IV-TR criteria for PTSD and alcohol dependence were recruited from a substance use treatment facility and were randomly assigned to receive either modified prolonged exposure (mPE) therapy for PTSD or a non-trauma-focused comparison treatment. Compared to adults in a non-OUD comparison group (n = 74), adults with OUD (n = 52) were younger, reported more cravings for alcohol, were more likely to use amphetamines and sedatives, were hospitalized more frequently for drug- and alcohol-related problems, and suffered from more severe PTSD symptomatology, depressive symptoms, and anxiety, standardized mean differences = 0.36-1.81. For participants with OUD, mPE was associated with large reductions in PTSD symptomatology, sleep disturbances, and symptoms of anxiety and depression, ds = 1.08-2.56. Moreover, participants with OUD reported decreases in alcohol cravings that were significantly greater than those reported by the non-OUD comparison group, F(1, 71.42) = 6.37, p = .014. Overall, our findings support the efficacy of mPE for PTSD among individuals who engage in problematic drinking and concurrent opioid misuse, despite severe baseline symptoms.

Opioid medication misuse among unhealthy drinkers

BACKGROUND

Combining opioid medications and alcohol has serious implications for patient health, including overdose. Information regarding those who use/misuse opioid medications and engage in unhealthy alcohol use is limited to pharmacological and epidemiological descriptions. This study presents opioid medication misuse and behavioral, mental, and physical health characteristics of persons filling opioid medications that are engaged in unhealthy alcohol use.

METHODS

We conducted a cross-sectional survey at 5 community pharmacies in Southwestern, Pennsylvania among patients filling opioid medications. Respondents completed validated opioid medication misuse, alcohol use, illicit drug use, depression, posttraumatic stress disorder (PTSD), and physical health functioning assessments. We present univariate and multivariate statistics describing opioid medication misuse and health risks among those positive for unhealthy alcohol use.

RESULTS

A total of 344 patients completed the survey (75.8% response). A total of 15.9% of respondents screened positive for opioid medication misuse, of whom 20.3% reported unhealthy alcohol use. Taking opioid medications too often was reported among a larger proportion of the sample with unhealthy alcohol use (34.3%) compared to those without (22.1%, p=0.04). Further, among respondents with unhealthy alcohol use, illicit drug use (Adjusted odds ratio [AOR]=12.14, 95% Confidence Interval [CI]=1.64-89.72) and PTSD (AOR=9.77, 95% CI=1.70-56.11) were associated with increased odds for opioid medication misuse.

CONCLUSION

Results suggest respondents with unhealthy alcohol use had distinct health profiles, which may place them at risk for opioid misuse and adverse events, such as overdose. Continued research must work to further understand these relationships and identify intervention and treatment strategies.

The effect of post-traumatic stress disorder on the risk of developing prescription opioid use disorder: Results from the National Epidemiologic Survey on Alcohol and Related Conditions III

OBJECTIVE

To evaluate the effect of baseline post-traumatic stress disorder (PTSD) and each symptoms cluster on the risk of developing opioid use disorder (OUD) in those exposed to opioid painkillers and to assess the effect of comorbid PTSD and OUD on functioning, OUD severity, and treatment seeking compared with individuals with OUD only.

METHODS

We obtained data from 4025 individuals exposed to opioid painkillers from the National Epidemiologic Survey on Alcohol and Related Conditions III. We matched individuals with baseline PTSD with individuals without PTSD on demographics, developmental background, family history, personalities, and exposure to stressful life events with propensity score methodology. We controlled for clinical diagnoses and other risk factors that may have occurred after PTSD onset. Quality of life was assessed with the SF-12; the number of diagnostic criteria met indicated OUD severity.

RESULTS

Baseline PTSD predicted OUD after controlling for matching variables and other risk factors, including baseline mood/anxiety disorders and other substance use disorders (odds ratio[OR]: 1.58; 95% confidence interval[CI]: 1.14-2.17; p=0.02). Among individuals with PTSD, arousal/reactivity cluster predicted OUD. Individuals with comorbid PTSD and OUD had lower mean scores on the SF-12 scale and greater severity of OUD than individuals with OUD. There were no differences in help-seeking.

CONCLUSION

Baseline PTSD increases the risk of developing OUD after exposure to opioid painkillers. Clinicians should screen for PTSD diagnosis and arousal/reactivity symptoms prior to prescribing painkillers. Integrated treatments are strongly recommended for patients with this dual diagnosis.

Comorbid Post-Traumatic Stress Disorder and Opioid Dependence

Post-traumatic stress disorder (PTSD) is predominant amongst individuals addicted to opioids and obscures the course of illness and the treatment outcome. We report the case of a patient with major depressive disorder and opioid dependence, who experienced post-traumatic stress disorder symptoms during a recent visit to the inpatient unit. The similarity of symptoms between post-traumatic stress disorder and opioid dependence is so high that, sometimes, it is a challenge to differentiate between these conditions. Since opioid withdrawal symptoms mimic hyper vigilance, this results in an exaggeration of the response of patients with post-traumatic stress disorder. This comorbidity is associated with worse health outcomes, as its pathophysiology involves a common neurobiological circuit. Opioid substitution therapy and psychotherapeutic medications in combination with evidence-based cognitive behavioral therapy devised for individuals with comorbid post-traumatic stress disorder and opioid dependence may improve treatment outcomes in this population. Therefore, we conclude that the screening for post-traumatic stress disorder in the opioid-abusing population is crucial. To understand the underlying mechanisms for this comorbidity and to improve the treatment response, further research should be encouraged.

Screening Community Pharmacy Patients for Risk of Prescription Opioid Misuse

OBJECTIVES

This study tested screening feasibility and described the behavioral, mental, and physical health of patients filling prescriptions for opioid medications in the community pharmacy setting.

METHODS

We conducted a cross-sectional survey in rural/urban community pharmacies with adult noncancer patients. The survey included validated measures for opioid medication misuse risk, drug and alcohol use, and physical and mental health problems. Descriptive statistics were calculated, and bivariate and multivariable logistic regression evaluated relationships between opioid medication misuse risk and patient demographics, behavioral, mental, and physical health.

RESULTS

A total of 164 patients completed the survey (87% response rate), revealing positive screens for prescription opioid misuse risk (14.3%), illicit drug use (7.3%), hazardous alcohol use (21.4%), depression (25.8%), and posttraumatic stress disorder (PTSD; 17.1%). Bivariate analyses revealed increased odds of a positive opioid medication misuse risk score with a positive screen for illicit drug use in the previous year (odds ratio = 3.91; 95% confidence interval [CI], 1.05-14.63) and PTSD (odds ratio = 6.7; 95% CI, 2.54-17.69). In adjusted multivariable analyses, these relationships strengthened such that a positive screen for illicit drug use (adjusted odds ratio = 12.96; 95% CI, 2.18-76.9) and PTSD (adjusted odds ratio = 13.3; 95% CI, 3.48-50.66) increased odds for a positive opioid medication misuse risk score.

CONCLUSIONS

Findings confirmed the feasibility of screening risk factors and positive opioid medication misuse risk among community pharmacy patients. Future research should validate these findings as a foundation to intervention development.

Effect of traumatic event reexposure and PTSD on substance use disorder treatment response

BACKGROUND

A remarkably high rate of traumatic event reexposure has been demonstrated in community-based substance users which negatively impacts their substance use disorder (SUD). The rate and effect of such reexposure in treatment is unknown. Despite increasing evidence that a diagnosis of posttraumatic stress disorder (PTSD) has little influence on long-term SUD treatment outcomes, it is possible that PTSD symptom fluctuations could have effects.

METHODS

This prospective longitudinal study examined the rate and effect of traumatic event reexposure and PTSD symptoms in 169 male and female methadone maintenance patients with a comorbid psychiatric disorder who were participating in a parent study. Traumatic events and PTSD symptoms were tested for association with drug use, treatment interruption, and counseling adherence in the same month, one month later, and two months later.

RESULTS

Approximately 18% of patients were reexposed to a traumatic event each month during the 12-month study. Reexposure was associated with about twice the risk of treatment interruption in the same month and one month later. Every 10% increase in PTSD symptom severity was associated with a 36% increased risk of treatment interruption two months later. No effects were seen on drug use or counseling adherence.

CONCLUSIONS

SUD patients have a relatively high rate of traumatic event reexposure. Both traumatic events and PTSD symptoms are associated with increased risk of treatment interruption, resulting in SUD patients leaving treatment at precisely the time they could benefit from treatment support.

Disclosure of Use and Abuse of Controlled Substances Among Psychiatric Outpatients

BACKGROUND

Prescription drug abuse is a serious health concern and is considered a nationwide epidemic. Patients often fail or refuse to disclose the use of controlled substances, leaving prescribers and pharmacies unaware of the potential for harmful drug interactions and risk of overdose. Psychiatric patients are especially vulnerable to controlled substance misuse.

OBJECTIVES

To determine hazardous patterns of prescription drug use among psychiatric outpatients and to raise awareness about the importance of reviewing information provided by prescription drug monitoring programs (PDMPs).

METHODS

The medical records of 150 patients attending the Adult Outpatient Psychiatric Clinic at the Los Angeles County+University of Southern California (LAC+USC) Medical Center from July 2012 through May 2013 were reviewed. Patient activity reports were generated from California's PDMP. Nondisclosure of controlled substance use was identified by a discrepancy between patient reporting of prescriptions according to the medical records and PDMP reports. A "pattern suggestive of prescription drug abuse" was defined as having one or more of the following: within-class prescriptions from multiple providers and/or within-class early refills or within-class overlapping prescriptions picked up within 10 days of each other.

RESULTS

Of the 150 patients, 113 were found in California's PDMP database. Of these 113 patients, 81 had obtained 111 prescriptions for controlled substances in the past 12 months. Of these 111 prescriptions, 52 (47%) were not disclosed to the primary psychiatrist, of which 14 (27%) revealed patterns consistent with prescription drug abuse.

CONCLUSIONS

Reviewing PDMP databases before prescribing controlled substances should be considered a standard prescribing practice to prevent abuse, diversion, and adverse medical outcomes.

The impact of addiction medications on treatment outcomes for persons with co-occurring PTSD and opioid use disorders

BACKGROUND AND OBJECTIVES

Previous research has been inconclusive about whether adding psychosocial treatment to medication assisted treatment (MAT) improves outcomes for patients with co-occurring psychiatric and opioid use disorders. This study evaluated the impact of MAT and psychosocial therapies on treatment outcomes for patients with co-occurring opioid use disorders and PTSD.

METHODS

Patients meeting criteria for PTSD and substance use disorders were randomly assigned to one of three treatment conditions: Standard Care (SC) alone, Integrated Cognitive Behavioral Therapy (ICBT) plus SC, or Individual Addiction Counseling (IAC) plus SC. Substance use and psychiatric symptoms were assessed at baseline and 6 months. Only patients with opioid use disorders were included in the present analyses (n = 126). Two-way ANOVAS and logistic regression analyses were used to examine associations between treatment conditions and MAT, for substance use and psychiatric outcomes.

RESULTS

MAT patients receiving ICBT had significantly decreased odds of a positive urine drug screen, compared to non-MAT patients receiving SC alone (OR = .07, 95% CI = .01, .81, p = .03). For PTSD symptoms, a significant MAT by psychosocial treatment condition interaction demonstrated that MAT patients had comparable declines in PTSD symptoms regardless of psychosocial treatment type (F(2, 88) = 4.74, p = .011). Non-MAT patients in ICBT had significantly larger reductions in PTSD.

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

For patients with co-occurring opioid use disorders and PTSD, MAT plus ICBT is associated with more significant improvement in substance use. For non-MAT patients, ICBT is most beneficial for PTSD symptoms.

Anxiety and substance use disorders: co-occurrence and clinical issues

The co-occurrence of substance use disorders (SUDs) and anxiety disorders has been now well established. This association is frequent and can be explained by three models: the shared vulnerability factors model, the self-medication model, and the substance-induced model. General population epidemiological studies provide strong evidence of the frequency of the association for the most used substances: tobacco, alcohol, cannabis, and to a lesser extent sedatives, opiates, and cocaine. For substances that are less commonly used in the general population, the frequency of the co-occurrence can more precisely be studied in clinical samples. We provide the most recent literature results on the association of SUDs and anxiety, and evidence for one explicative model or the other when available. For substances with sedative properties (alcohol, benzodiazepines, cannabis, opioids), both evidence for a self-medication and for a toxic effect exist. For substances with psychostimulant properties (tobacco, cocaine, and amphetamines), the literature favors the toxic hypothesis to explain the association with anxiety disorders. We give practical steps for the recognition of these dual diagnoses and present therapeutic issues, although the strategies are rarely evidence based.

Initial response as a predictor of 12-week buprenorphine-naloxone treatment response in a prescription opioid-dependent population

OBJECTIVE

Initial medication response has been shown to predict treatment outcome across a variety of substance use disorders, but no studies have examined the predictive power of initial response to buprenorphine-naloxone in the treatment of prescription opioid dependence. We therefore conducted a secondary analysis of data from the Prescription Opioid Addiction Treatment Study to determine whether initial response to buprenorphine-naloxone predicted 12-week treatment outcome in a prescription opioid-dependent population.

METHOD

Using data from a multisite, randomized controlled trial of buprenorphine-naloxone plus counseling for DSM-IV prescription opioid dependence (June 2006-July 2009), we conducted a secondary analysis to investigate the relationship between initial medication response and 12-week treatment outcome to establish how soon the efficacy of buprenorphine-naloxone could be predicted (N = 360). Outcomes were determined from the Substance Use Report, a self-report measure of substance use, and confirmatory urinalysis. Predictive values were calculated to determine the importance of abstinence versus use at various time points within the first month of treatment (week 1, weeks 1-2, 1-3, or 1-4) in predicting successful versus unsuccessful treatment outcome (based on abstinence or near-abstinence from opioids) in the last 4 weeks of buprenorphine-naloxone treatment (weeks 9-12).

RESULTS

Outcome was best predicted by medication response after 2 weeks of treatment. Two weeks of initial abstinence was moderately predictive of treatment success (positive predictive value = 71%), while opioid use in both of the first 2 weeks was strongly predictive of unsuccessful treatment outcome (negative predictive value [NPV] = 84%), especially when successful outcome was defined as total abstinence from opioids in weeks 9-12 (NPV = 94%).

CONCLUSIONS

Evaluating prescription opioid-dependent patients after 2 weeks of buprenorphine-naloxone treatment may help determine the likelihood of successful outcome at completion of the current treatment regimen.
