Diagnosing and managing prescription opioid use disorder in patients prescribed opioids for chronic pain in Australian general practice settings: a qualitative study using the theory of Planned Behaviour.

BACKGROUND: Chronic pain is a debilitating and common health issue. General Practitioners (GPs) often prescribe opioids to treat chronic pain, despite limited evidence of benefit and increasing evidence of harms, including prescription Opioid Use Disorder (pOUD). Australian GPs are worried about the harms of long-term opioids, but few are involved in the treatment of pOUD. There is little research on GPs' experiences diagnosing and managing pOUD in their chronic pain patients. METHODS: This qualitative research used semi-structured interviews and a case study to investigate GPs' experiences through the lens of the Theory of Planned Behaviour (TPB). TPB describes three factors, an individual's perceived beliefs/attitudes, perceived social norms and perceived behavioural controls. Participants were interviewed via an online video conferencing platform. Interviews were transcribed verbatim and thematically analysed. RESULTS: Twenty-four GPs took part. Participants were aware of the complex presentations for chronic pain patients and concerned about long-term opioid use. Their approach was holistic, but they had limited understanding of pOUD diagnosis and suggested that pOUD had only one treatment: Opioid Agonist Treatment (OAT). Participants felt uncomfortable prescribing opioids and were fearful of difficult, conflictual conversations with patients about the possibility of pOUD. This led to avoidance and negative attitudes towards diagnosing pOUD. There were few positive social norms, few colleagues diagnosed or managed pOUD. Participants reported that their colleagues only offered positive support as this would allow them to avoid managing pOUD themselves, while patients and other staff were often unsupportive. Negative behavioural controls were common with low levels of knowledge, skill, professional supports, inadequate time and remuneration described by many participants. They felt OAT was not core general practice and required specialist management. This dichotomous approach was reflected in their views that the health system only supported treatment for chronic pain or pOUD, not both conditions. CONCLUSIONS: Negative beliefs, negative social norms and negative behavioural controls decreased individual behavioural intention for this group of GPs. Diagnosing and managing pOUD in chronic pain patients prescribed opioids was perceived as difficult and unsupported. Interventions to change behaviour must address negative perceptions in order to lead to more positive intentions to engage in the management of pOUD.

Breaking Free From the "War on Drugs": Examples From Three Leader States.

While the federal government continues to pursue a punitive "War on Drugs," some states have adopted evidence-based, human-focused approaches to reducing drug-related harm. This article discusses recent legal changes in three states that can serve as models for others interested in reducing, rather than increasing, individual and community harm.

Crossroads of Care: Navigating Injection Drug Use-Associated Endocarditis.

Infective endocarditis (IE), with its high morbidity and mortality, is a frequent complication of injection drug use (IDU). We present a case highlighting the complexities in the management of IDU-associated IE (IDU-IE) in a 46-year-old male with active IDU who presented with methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia and a large tricuspid valve vegetation. Urgent tricuspid valve surgery was indicated due to the size of the vegetation measuring up to 4 cm, along with recurrent pulmonary septic emboli. The patient underwent an uncomplicated and successful complete vegetectomy, tricuspid valve repair, and completed a 42-day antibiotic course. During the six-week follow-up, he showed complete recovery and maintained successful abstinence from illicit drug use, supported by an addiction medicine specialist. This case underscores the importance of early recognition, appropriate antibiotic therapy, and individualized surgical intervention in optimizing outcomes. Effective management of IE necessitates a multidisciplinary IE team, including addiction medicine specialists. Addressing the underlying substance use disorder (SUD) is crucial to reducing the risk of recurrent IE.

The Role of Perceived Stress in the Relation between Childhood Maltreatment and Severity of Alcohol Use Disorder: A Mediation Analysis.

INTRODUCTION: Experiences of Childhood Maltreatment (CM) relate to relapse and lower treatment success in Alcohol Use Disorder (AUD), one of the most prevalent substance use disorders. However, the exact mechanisms of this relationship still remain unclear. This study examines perceived stress and "drinking to cope with negative affect" (coping) as possible mediators in this relationship. Moreover, it aims at uncovering the differential effects of the subtypes of CM. METHODS: N = 96 individuals (42% women; mean age 41 ± 13 years) including healthy controls and individuals with varying severity of AUD and CM completed the Alcohol-Dependence Scale, Childhood Trauma Questionnaire, Perceived Stress Scale and German Inventory of Drinking Situations. Mediation analyses including perceived stress as a mediator between CM (and subtypes) and severity of AUD, as well as a serial mediation of the relationship between CM and AUD severity by perceived stress and coping were conducted. RESULTS: Perceived stress significantly mediated the relation between CM and AUD severity and the serial mediation by perceived stress and coping turned out significant. Subtype-specific analyses did not yield significant results. CONCLUSION: This study reinforces perceived stress as a potential mechanism in the relation between CM and AUD severity. Moreover, coping further mediated the relationship between CM and AUD severity. Our results suggest including screening for CM (subtypes) in clinical routine in order to individually emphasize interventions focusing on stress regulation, as well as on developing healthy coping mechanisms, in patients with AUD. This might prevent heightened stress sensitivity, relapse and further maintenance of AUD.

Nurse led models of care for outpatient substance use disorder treatment: A scoping review.

AIM: To map key characteristics and describe nurse led models of care for the treatment of persons with substance use disorders (SUDs) in the outpatient setting. DESIGN: A scoping review. METHODS: Conducted in accordance with the JBI methodology. The PRISMA-ScR checklist was used. DATA SOURCES: Pubmed, CINAHL Complete (EBSCOhost), Cochrane Library, APA PsycNet and Scopus were searched from 1999 to May 2022 and updated on 28 November 2023. A handsearch and a grey literature search was conducted. RESULTS: Title and abstract screening was performed on 774 articles resulting in 88 articles for full text screening. Full text screening yielded 13 articles that met inclusion criteria. CONCLUSION: Existing nurse-led models of care for SUDS are scarce and limited in scope, with the majority focused on treating opioid use disorder. Additional research is needed to develop, test, and implement efficacious nurse-led models of care for the treatment and management of SUDs. IMPLICATIONS TO CLINICAL PRACTICE: Nurse led models of care have demonstrated their efficacy and quality in the management of other chronic diseases. As we move forward with innovative solutions for individuals with addiction, nurse led models of care can be a mechanism to deliver high quality, evidence-based care for SUDs. IMPACT: SUDs are chronic diseases that impact individuals, families, and communities. SUDs require a biopsychosocial approach to treatment. Globally, nurses are well positioned to provide high quality care to mitigate the impact of SUDs. This scoping review mapped the extant literature on nurse led models of care for substance use disorder treatment in the outpatient setting finding that additional research is needed to develop, test and implement evidence-based interventions to care for individuals, families, and communities experiencing SUDs. REPORTING METHOD: PRISMA checklist for scoping reviews. No patient or public contribution were part of this study.

Neurocognitive and clinical profile of male patients with substance use disorder in early remission phase with and without comorbid depression.

Substance Use Disorder (SUD) represents one of the most frequent conditions worldwide which commonly coexists with major depressive disorder (MDD). This comorbidity (SUD + MDD) is one of the most prevalent with patients showing certain social and clinical characteristics that could lead to a worsening of their cognitive performance. However, despite these particularities, only a few studies have addressed the possible differences in cognitive performance between patients with SUD + MDD compared with those with SUD-only patients. Therefore, the aim of this study is to examine the clinical and cognitive profile of patients with SUD + MDD vs. SUD-only who are in early remission phase. For this purpose, 271 male patients underwent a clinical and neuropsychological assessment (SUD + MDD group: N = 101; SUD-only group: N = 170). Results indicated that SUD + MDD patients showed worse cognitive performance than SUD in visuospatial reasoning, verbal memory and learning, recognition, and processing speed even after a 3-month period of abstinence. Furthermore, these patients exhibited more self-reported prefrontal symptoms, as well as worse social and clinical conditions. This study indicates that the neurocognitive and clinical profile of patients with SUD + MDD could represent a risk since their characteristics have been associated with poorer recovery and prognosis. Our results could be helpful in clinical practice highlighting the need for cognitive remediation strategies in these populations, providing information that would allow the implementation of more appropriate treatments and preventive strategies.

Substance Use Disorder as Risk Factor for Intubation in Angioedema: A Nationwide Cohort Study.

OBJECTIVES: Individuals with angioedema (AE) are at high risk for airway compromise and often require endotracheal intubation. Patient factors predisposing one to airway compromise are not well described. The objective of this study is to examine whether substance use disorder (SUD) in patients with AE is associated with need for airway intervention. METHODS: This population-based retrospective cohort study compared AE patients with SUD versus propensity-matched control groups. Outcomes were hospitalization, intubation, and tracheotomy. Using the TriNetX National Database, this study included 28,931 patients with SUD and 117,509 patients without SUD who presented with AE. RESULTS: Among patients with AE, those with each subtype of SUD (alcohol, cannabis, cocaine, tobacco, and opioids) were found to have higher risk of severe AE compared to propensity-matched non-SUD cohorts. Rate of hospitalization after cohort matching ranged from 20.4% for tobacco use disorder to 30.4% for cocaine use disorder, all significantly higher than the 8.0% in a population without SUD. Each SUD subtype was associated with a higher rate of intubation compared with matched non-SUD groups, with cannabis use disorder having the highest relative risk (RR) of 3.67 (95% CI: 2.69-5.02). Tobacco (RR = 2.45, 95% CI: 1.79-3.34) and alcohol (RR = 2.82, 95% CI: 1.73-4.58) use disorders were both associated with significantly higher risk of tracheotomy. CONCLUSION: These data suggest that patients with SUD, regardless of subtype, and after propensity matching for demographics and comorbidities are at higher risk for adverse outcomes when presenting with AE. This study highlights clinically relevant predictors of airway compromise. LEVEL OF EVIDENCE: Level 3 Laryngoscope, 2024.

"Even Though the System Had Failed Him His Entire Life, We Were Failing Him Yet Again": How Clinical, Welfare, and Penal Medicine Interact to Drive Health Inequities and Medical Moral Injury.

Adam, a justice-involved young man, was brought into the emergency department at the county hospital in cardiogenic shock due to a recurring episode of injection-drug-use-related infective endocarditis (IDU-IE). Adam had initiated injection opioid use in prison. He was surgically treated for the previous episodes of IDU-IE but was unable to fully recover due to limitations in care within penal medicine. This case report explores the prison as a determinant of health, interactions between clinical, welfare, and penal medicine, to produce and maintain health inequities, and structural drivers of physician moral injury through an interview with Adam and reflexive writings from emergency medicine physicians. This case demonstrates the need for three types of structural health interventions: (1) restorative justice, community-based reentry programs, and housing as welfare medicine, (2) increased harm reduction services across healthcare, especially penal medicine, and (3) equitable institutional protocols (contrary to ambiguous guidelines) to treat clinical conditions like IDU-IE that disproportionately impact structurally vulnerable patients.

Hepatitis C Presenting Like Endocarditis in a Young Patient With Substance Use Disorder: A Case Report.

This case report details a 21-year-old male patient who initially presented with endocarditis-like symptoms but ultimately had hepatitis C in the setting of substance use disorder. It highlights the value of prompt diagnosis and effective treatment. He had a medical history of chronic heroin use over two years and presented inconsistently to the emergency department with generalized body aches. He had generalized body pain and right upper and lower quadrant abdominal pain. He had been unable to tolerate any oral intake and had been vomiting after every meal for the last three weeks. Physical examination was significant only for large, ovoid, erythematous nodules on the left dorsal foot, blanching and slightly painful to touch; diffuse scabs and sores on extremities; and nodules on dorsal interphalangeal joints on the left hand. Urine drug screen was noted to be positive for cannabinoids, methamphetamines, and opioids. The initial electrocardiogram did not show typical T wave flattening changes for hypokalemia. Transthoracic echocardiogram ruled out infective endocarditis, with no valvular vegetation. He was ultimately found to be hepatitis C virus antibody positive. This case illustrates the importance of keeping a wide differential in mind. The patient had hepatitis C despite being asymptomatic throughout presentation-keeping. The patient's history of heroin use was critical while ordering testing.

The methods and baseline characteristics of a multi-site randomized controlled trial evaluating mindfulness-based relapse prevention in conjunction with peer support to improve adherence to medications for opioid use disorders.

Introduction: Medications for opioid use disorders (MOUD) remain the gold standard for treating OUD, but treatment initiation and adherence remain challenging. Exclusive utilization of pharmacotherapy as a treatment modality for OUD is sub-optimal, and a combination of psychotherapies and pharmacotherapies is recommended. General trends indicate the benefits of peer mentoring and MBRP separately. Therefore, we hypothesize that the combined effect of MBRP and Peer mentoring will produce synergistic improvements in MOUD adherence compared to an enhanced twelve-step facilitation (TSF). Methods: This paper describes the methods and baseline characteristics of a multi-site randomized controlled trial evaluating the effectiveness of a combination of MBRP and peer support (MiMP) compared to an enhanced TSF in improving adherence to MOUD. Both MiMP and TSF are 12-week manualized protocols that utilize licensed therapists. The interventions are delivered in weekly group sessions that last about 75-90 minutes per session. The primary outcome is MOUD adherence. Secondary and exploratory outcomes include relapse, cravings, depression, anxiety, stress, quality of life, and pain catastrophizing. Results: The participants' ages ranged from 21 years to 77 years, with a mean age of 44.5 (SD ± 11.5 years). There was an almost equal distribution of gender and place of residence. Overall, 51.9% (n=54) of participants identified as female and 48.1% (n=50) were male. Similarly, 51.9% (n=54) of participants resided in urban areas, while 48.1% (n=50) resided in rural areas. Participants identified as either black or white, with over three-quarters identifying as white (77.9%, n= 81) and 22.1% (n= 23) as black. Most participants randomized to the 12-step facilitation group were white (93.1%). Relationships and employment status were well distributed between categories. Over half of the participants reported some college or higher education. Over 90% of the participants made less than $75,000 per year. Some participants indicated that they had both public and private health insurance. Discussion and conclusion: This study is innovative in several ways including combining MBRP and peer support, addressing comorbid mental health issues among individuals with OUD, utilizing manualized protocols, and evaluating of both physiological and self-reported measures in assessing cortisol reactivity as a predictor of relapse and treatment outcomes.

Heterogeneity in choice models of addiction: the role of context.

RATIONALE: Theories of addiction guide scientific progress, funding priorities, and policy development and ultimately shape how people experiencing or recovering from addiction are perceived and treated. Choice theories of addiction are heterogenous, and different models have divergent implications. This breeds confusion among laypeople, scientists, practitioners, and policymakers and reduces the utility of robust findings that have the potential to reduce the global burden of addiction-associated harms. OBJECTIVE: Here we differentiate classes of choice models and articulate a novel framing for a class of addiction models, called contextual models, which share as a first principle the influence of the environment and other contextual factors on behavior within discrete choice contexts. RESULTS: These models do not assume that all choice behaviors are voluntary, but instead that both proximal and distal characteristics of the choice environment-and particularly the benefits and costs of both drug use and non-drug alternatives-can influence behavior in ways that are outside of the awareness of the individual. From this perspective, addiction is neither the individual's moral failing nor an internal uncontrollable urge but rather is the result of environmental contingencies that reinforce the behavior. CONCLUSIONS: Contextual models have implications for guiding research, practice, and policy, including identification of novel target mechanisms while also improving existing interventions.

Certified Community Behavioral Health Clinic Services for Clients With Co-occurring Disorders: A Latent Class Approach.

OBJECTIVE: Certified community behavioral health clinics (CCBHCs) are designed to provide comprehensive care for individuals with co-occurring mental and substance use disorders. The authors classified outpatient mental health treatment facilities on the basis of provision of services for clients with co-occurring disorders and assessed whether CCBHCs differed from other outpatient mental health facilities in services provided. METHODS: The authors used latent class analysis to identify distinct services for clients with co-occurring disorders in 5,692 outpatient mental health facilities in the 2021 National Substance Use and Mental Health Services Survey. Nine indicators were included: treatment for clients with substance or alcohol use disorder co-occurring with serious mental illness or serious emotional disturbance, specialized programs or groups for such clients, medication-assisted treatment (MAT) for alcohol use disorder, MAT for opioid use disorder, detoxification, individual counseling, group counseling, case management, and 12-step groups. A multinomial logistic regression was used to estimate whether CCBHCs were associated with any identified classes after analyses controlled for facility characteristics. RESULTS: A four-class solution provided a model with the best fit, comprising comprehensive services (23.4%), case management services (17.7%), counseling and self-help services (58.6%), and professional services (4.3%). Regressing class membership on facility type and covariates, the authors found that compared with community mental health clinics (CMHCs), CCBHCs were more likely to belong to the comprehensive services class than to the case management services, counseling and self-help services, and professional services classes. CONCLUSIONS: CCBHCs were more likely than other outpatient programs to offer comprehensive care, and CCBHC status of a CMHC facilitated enhanced service provisions.

A replication study using the World Health Organization pharmacovigilance database (VigiBase®) to evaluate whether an association between ketamine and esketamine and alcohol and substance misuse exists.

BACKGROUND AND OBJECTIVES: Ketamine and esketamine are increasingly prescribed in the treatment of resistant mood disorders and persons at risk of suicide. Ketamine is a drug of misuse with increasing non-therapeutic use in the general population. Herein, our aim was to determine whether ketamine and/or esketamine are disproportionately associated with reports of substance and/or alcohol misuse. METHODS: Replicating a similar analysis recently conducted using the Food and Drug Administration Adverse Event Reporting System (FAERS) database, we identified cases of "alcohol problem, alcoholism, alcohol abuse, substance dependence, substance use disorder (SUD), substance abuse, drug dependence, drug use disorder and drug abuse" in association with ketamine and esketamine reported to the World Health Organization Pharmacovigilance Database (WHO VigiBase). We searched the database from inception to January 2024. The reporting odds ratio (ROR) of each of the aforementioned parameters was calculated; acetaminophen was used as the control. The numerator of the equation represents the number of cases (n) and the denominator represents the total cases of psychiatric disorders (N). Significance was obtained when the lower limit of the 95 % confidence (CI) > 1.0. RESULTS: The RORs for ketamine was increased for most parameters (i.e., alcohol abuse (3.24), substance dependence (12.48), substance use disorder (170.44), substance abuse (2.94), drug dependence (2.88), drug use disorder (11.54) and drug abuse (2.85), respectively). With respect to esketamine, the RORs were observed to be different from ketamine insofar as we observed a reduction in the RORs for three parameters (i.e., substance abuse (0.41), drug dependence (0.083) and drug abuse (0.052), respectively). The IC025 values were significant for ketamine in cases of alcohol abuse (0.35), substance dependence (0.50), substance use disorder (2.77), substance abuse (0.83), drug dependence (0.97), drug use disorder (1.95) and drug abuse (0.94). Additionally, oxycontin showed significant IC025 values for substance use disorder (0.0014), substance abuse (0.042), and drug dependence (0.17). CONCLUSION: Esketamine was not associated with an increased ROR for any parameter of alcohol and/or substance use disorder. Mixed results were observed with ketamine with some RORs increased and others decreased. Estimating RORs using a pharmacovigilance database does not establish causation in the case of elevated RORs and cannot be assumed to be a therapeutic effect when lower RORs were observed.

The auditory stimulus facilitates memory guidance in distractor suppression in males with substance use disorder.

Introduction: Representations in working memory can affect distractor suppression in human visual search, and this process is modulated by a separate top-down cognitive control. An increasing body of research has demonstrated that patients with substance use disorder (SUD) have deficits in cognitive control over filtering interference by perceptual distractors. However, their ability to resist proactive interference from working memory has received comparatively less attention. Methods: Here, we investigate this issue by employing a working memory/visual search dual-task paradigm. An intervening gap-location search task was instructed to be performed while participants memorized a written color word, with congruent auditory information present during the memory encoding phase on half of the trials. Results: Results showed that there was a reliable response time (RT) advantage when the meaning of the memory sample agreed with the color of one of the distractors under the visual alone condition. However, such a result was only found in the control group. More importantly, both groups exhibited comparable facilitation under the audiovisual condition, with the facilitation effect appearing later in the SUD group. Furthermore, the facilitation effect was superior in magnitude and time course under the audiovisual condition to the visual alone condition. Discussion: These findings highlight how patients with SUD resist distractor interference at the memory level and extend our understanding of how working memory, selective attention, and audiovisual enhancement interact to optimize perceptual decisions in patients with SUD.

Uptake of COVID-19 vaccination among community-dwelling individuals receiving healthcare for substance use disorder and major mental illness: a matched retrospective cohort study.

Introduction: Patients with major mental illness (MMI) and substance use disorders (SUD) face barriers in accessing healthcare. In this population-based retrospective cohort study, we investigated the uptake of COVID-19 vaccination in Ontario, Canada among community-dwelling individuals receiving healthcare for major mental illness (MMI) and/or substance use disorders (SUD), comparing them to matched general population controls. Methods: Using linked health administrative data, we identified 337,290 individuals receiving healthcare for MMI and/or SUD as of 14 December 2020, matched by age, sex, and residential geography to controls without such healthcare. Follow-up extended until 31 December 2022 to document vaccination events. Results: Overall, individuals receiving healthcare for MMI and/or SUD (N = 337,290) had a slightly lower uptake of first (cumulative incidence 82.45% vs. 86.44%; hazard ratio [HR] 0.83 [95% CI 0.82-0.83]) and second dose (78.82% vs. 84.93%; HR 0.77 [95% CI 0.77-0.78]) compared to matched controls. Individuals receiving healthcare for MMI only (n = 146,399) had a similar uptake of first (87.96% vs. 87.59%; HR 0.97 [95% CI 0.96-0.98]) and second dose (86.09% vs. 86.05%, HR 0.94 [95% CI 0.93-0.95]). By contrast, individuals receiving healthcare for SUD only (n = 156,785) or MMI and SUD (n = 34,106) had significantly lower uptake of the first (SUD 78.14% vs. 85.74%; HR 0.73 [95% CI 0.72-0.73]; MMI & SUD 78.43% vs. 84.74%; HR 0.76 [95% CI 0.75-0.77]) and second doses (SUD 73.12% vs. 84.17%; HR 0.66 [95% CI 0.65-0.66]; MMI & SUD 73.48% vs. 82.93%; HR 0.68 [95% CI 0.67-0.69]). Discussion: These findings suggest that effective strategies to increase vaccination uptake for future COVID-19 and other emerging infectious diseases among community-dwelling people with SUD are needed.

Associations Between Drug Overdose Mortality and Recovery Ecosystems in the United States: A County-Level Analysis Using a Novel Index.

BACKGROUND: Communities with robust recovery ecosystems could reduce negative outcomes associated with substance use disorders (SUDs) and facilitate the recovery process. This cross-sectional study examined the relationship between drug overdose mortality rates in the United States and the strength of county-level recovery ecosystems, as measured by the Recovery Ecosystem Index (REI). METHODS: The REI assesses the strength of county-level recovery ecosystems in the United States. Comprised of 14 indicators across 3 component classes, overall and component scores ranging from "one" (strongest) to "five" (weakest) were calculated for each county using standardized values of the indicators. County-level analyses included: (1) correlational analyses between drug overdose mortality rates (n = 2076) and REI scores (overall score and by component); and (2) quadrant analysis (n = 2076), dividing counties based on their drug overdose mortality rates and overall REI scores. RESULTS: Drug overdose mortality rates were inversely related to REI overall, SUD treatment component, and continuum of SUD support component scores, indicating that lower (stronger) scores corresponded to higher rates. Conversely, REI infrastructure and social component scores were positively related to rates. Counties were relatively evenly distributed across quadrants, with 26% (n = 537) with a strong REI score and high overdose mortality rate, 24% (n = 489) with a strong REI score and low overdose mortality rate, 20% (n = 409) with a weak REI and high overdose mortality rate, and 31% (n = 641) with a weak REI and low overdose mortality rate. CONCLUSIONS: REI scores were generally inversely associated with drug overdose mortality rates in US counties, suggesting that communities have stronger recovery systems and services as the burden of SUD increases. Given relative variation in the scale of drug overdose mortality and strength of recovery ecosystems among counties, results could guide the identification of communities where the need for expanded recovery systems and services may be particularly critical.

"Just as expensive as sending him to college:" barriers and perceptions of treatment in justice-involved youth.

BACKGROUND: Justice-involved youth have higher rates of substance use disorders (SUDs) than the general population. Many do not connect with or complete treatment, leading to recidivism. This qualitative study explores perceptions and barriers to treatment in this population. RESULTS: Justice-involved youth participating in a larger study focused on access to SUD treatment were interviewed about available treatment and justice system involvement. Twenty-one dyads (youth and a guardian) and 3 individual guardians (total N = 45) were interviewed by phone. Inclusion criteria were youth aged 14-17 involved in the justice system that screened positive for SUD. Youth sample was 43% male. Thematic analysis guided the process. The study was Indiana University Institutional Review Board approved (#1802346939). Data was interpreted within the ecological system theory. Youth barriers included willingness to engage in treatment, time constraints/scheduling conflicts, and low perceived usefulness of treatment. Major guardian themes included high cost of treatment, lack of communication by the justice system about treatment, youth unwillingness or disinterest to engage in treatment, and limited program availability. CONCLUSIONS: The barriers to treatment for justice-involved youth are multifaceted and occur across the spectrum of levels of the ecological system, which include parents, peers, social systems, and cultural elements. Many youth and guardians suggested improvements for their interactions with the juvenile justice system. Further examination is needed of current policy implementation to address these concerns.

Emergency Department-Based Medication for Opioid Use Disorder Program: Addressing Gaps in Linkages to Care.

Background Emergency department (ED)-based medication for opioid use disorder (MOUD) has been shown to be effective in providing ease of access and successful treatment rates for patients with opioid use disorder (OUD). This study examined the social determinants of health (SDOH) of patients entering an ED-based MOUD program through individual and focus group surveys. SDOH may impact treatment retention for current and future patients. Methods A survey of all patients entering our MOUD program at two hospital-based EDs and two free-standing EDs was conducted from January to March 2022. Addiction care coordinators (ACCs) used standardized screening tools to enroll patients into the MOUD program, and trained research coordinators used a standardized form, using previously validated survey questions, to examine the role of SDOH. Focused group surveys were also collected. The survey measured patients' perspectives of the program and solicited feedback on SDOH and program barriers. Results Of the 60 OUD patients inducted into the ED-based MOUD program during our survey period, 19 (32%) participated in an individual or focus group interview. Of these, 16 patients (27%) completed all survey questions. The mean age was 42 years old, 94% identified as Caucasian, and 65% were males. Over 94% of subjects found the ACCs helpful in providing follow-up care. Nearly 40% experienced transportation and financial issues. The vast majority found the MOUD program beneficial in coping with withdrawal symptoms, dealing with their addiction, and supporting recovery. Conclusion OUD patients found the ACCs and the MOUD program helpful for their transition to the treatment stage. The MOUD program can improve some patients' reluctance to engage with a healthcare system by addressing barriers related to transportation to appointments and financial issues.

Assessing Substance Use Disorder Symptoms with a Checklist among Primary Care Patients with Opioid Use Disorder and/or Long-Term Opioid Treatment: An Observational Study.

BACKGROUND: Primary care (PC) offers an opportunity to treat opioid use disorders (OUD). The Substance Use Symptom Checklist ("Checklist") can assess DSM-5 substance use disorder (SUD) symptoms in PC. OBJECTIVE: To test the psychometric properties of the Checklist among PC patients with OUD or long-term opioid therapy (LTOT) in Kaiser Permanente Washington (KPWA). DESIGN: Observational study using item response theory (IRT) and differential item functioning (DIF) analyses of measurement consistency across age, sex, race and ethnicity, and receipt of treatment. PATIENTS: Electronic health records (EHR) data were extracted for all adult PC patients visiting KPWA 3/1/15-8/30/2020 who had ≥ 1 Checklist documented and indication of either (a) clinically-recognized OUD (i.e., documented OUD diagnosis and/or OUD medication treatment) or (b) LTOT in the year prior to the checklist. MAIN MEASURE: The Checklist includes 11 items reflecting DSM-5 criteria for SUD. We described the prevalence of 2 SUD symptoms reported on the Checklist (consistent with mild-severe DSM-5 SUD). Analyses were conducted in the overall sample and in two subsamples (clinically-recognized OUD and LTOT only). KEY RESULTS: Among 2007 eligible patients, 39.9% endorsed ≥ 2 SUD symptoms (74.3% in the clinically-recognized OUD subsample and 13.1% in LTOT subsample). IRT indicated that a unidimensional model for the 11 checklist items had excellent fit (comparative fit index = 0.998) with high item-level discrimination parameters for the overall sample and both subsamples. DIF across age, race and ethnicity, and treatment was observed for one item each, but had minimal impact on expected number of criteria (0-11) patients endorse. CONCLUSIONS: The Substance Use Symptom Checklist measured SUD symptoms consistent with DSM-5 conceptualization (scaled, unidimensional) in patients with clinically-recognized OUD and LTOT and had similar measurement properties across demographic subgroups. The Checklist may support symptom assessment in patients with OUD and diagnosis in patients with LTOT.

Bovine colostrum supplementation as a new perspective in depression and substance use disorder treatment: a randomized placebo-controlled study.

Introduction: This randomized, placebo-controlled, double-blind, parallel study aimed to evaluate the effect of 3-month supplementation of bovine colostrum (BOV-COL; 8x400 mg per day) on the outcomes of depression treatment in hospitalized patients with substance use disorder (SUD). The hypothesis is that BOV-COL supplementation as an add-on treatment results in favorable alternations in selected blood inflammatory markers or neurotransmitters, leading to better depression treatment outcomes compared with placebo (PLA). Methods: Patients with a Minnesota Multiphasic Personality Inventory-2 score ≥60 points were enrolled. Twenty-nine participants (n=18 in the BOV-COL group and n=11 in the PLA group) completed the protocol. Results: The mean Beck Depression Inventory-II score was significantly reduced after supplementation in both groups. However, the mean 17-point Hamilton Depression Rating Scale score was decreased in the BOV-COL group, but not in the PLA group. In the BOV-COL group, there was a reduction in interleukin (IL)-1, IL-6, IL-10, the IL-6:IL-10 ratio, IL-17, and tumor necrosis factor alpha (TNF-α), while in the PLA group only IL-6 decreased. Favorable alternations in the total count and differentials of white blood cell subsets were more pronounced in the BOV-COL. There were no changes in neurotransmitter concentrations. Conclusions: BOV-COL supplementation is a promising add-on therapy in patients with depression and SUD.
