RESUMO

BACKGROUND: Anxiety, depression and pain catastrophizing are independently associated with risk of opioid misuse in patients with persistent pain but their relationship to current opioid misuse, when considered together, is poorly understood. This study will assess the relative contribution of these modifiable, and distinct psychological constructs to current opioid misuse in patients with persistent pain. METHODS: One hundred and twenty-seven patients referred to a specialized opioid management clinic for prescription opioid misuse within a tertiary pain service were recruited for this study. The Pain Catastrophizing Scale, Depression, Anxiety and Stress Scales and the Current Opioid Misuse Measure were administered pre-treatment. Pain severity and morphine equivalent dose based on independent registry data were also recorded. RESULTS: Higher levels of pain catastrophizing, depression, and anxiety were significantly associated with higher current opioid misuse (r = .475, 0.599, and 0.516 respectively, p < .01). Pain severity was significantly associated with pain catastrophizing (r = .301, p < .01). Catastrophizing, depression, and anxiety explained an additional 11.56% of the variance (R2 change = 0.34, p < .01) over and above age, gender, pain severity and morphine equivalent dose. Depression was the only significant variable at Step 2 (ß = 0.62, p < .01). CONCLUSION: Findings show that in a sample of people with persistent pain referred for treatment for opioid misuse, depression contributes over and above that of anxiety and pain catastrophizing. Theoretical and clinical practice implications are presented.

RESUMO

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

RESUMO

Emergency medical services (EMS) can be an invaluable ally of addiction medicine clinicians, but the potential role of EMS in combating the opioid epidemic has been under-realized. EMS has historically focused on emergency response and resuscitation in cases of overdose; however, EMS is also well-positioned to build rapport with persons who use drugs (PWUD), provide harm reduction services, and connect PWUD with additional treatment services and resources. A select number of EMS organizations have begun to offer substance-related programming that extends beyond resuscitation, but these offerings remain limited in scope and impact. This perspective argues that addiction medicine clinicians can bolster the ability of EMS to provide high quality substance-related services by engaging in prehospital care education, program development and research, and clinical care. This perspective shares practical strategies for addiction medicine clinicians to partner with EMS and considers several potential barriers that must be overcome, including bureaucratic challenges, variability in the scope of practice of EMS providers across different locations, and limited funding.

RESUMO

BACKGROUND: Drug overdose is a leading cause of death and opioid-related deaths increased by more than 300% from 2010 to 2020 in New York State. Experts holding a range of senior leadership positions from across New York State were asked to identify the greatest challenges in substance misuse prevention, harm reduction, and treatment continuum of care. Expert input was used to shape funding priorities. METHOD: Individual semi-structured interviews of sixteen experts were conducted in April and May 2023. Experts included academics, medical directors, leaders of substance misuse service agencies, administrators of a state agency, a county mental health commissioner, the president of a pharmacy chain, and a senior vice president of an addiction-related national non-profit. Zoom interviews were conducted individually by an experienced qualitative interviewer and were recorded, transcribed, and coded for content. An initial report, with the results of the interviews organized by thematic content, was reviewed by the research team and emailed to the expert interviewees for feedback. RESULTS: The research team identified five major themes: 1. Siloed and fragmented care delivery systems; 2. Need for a skilled workforce; 3. Attitudes towards addiction (stigma); 4. Limitations in treatment access; and 5. Social and drug related environmental factors. Most experts identified challenges in each major theme; over three-quarters identified issues related to siloed and fragmented systems and the need for a skilled workforce. Each expert mentioned more than one theme, three experts mentioned all five themes and six experts mentioned four themes. CONCLUSIONS: Research, educational, and programmatic agendas should focus on identified topics as a means of improving the lives of patients at risk for or suffering from substance use-related disorders. The results of this project informed funding of pilot interventions designed to address the identified care challenges.

RESUMO

Pregnancy can be a time of joy and hope but, for birthing parents struggling with a substance use disorder (SUD), it can be challenging. Social stigma, shame, and the potential legal ramifications present barriers to individuals seeking the care they need. Marginalized groups, in particular, face challenges that put them at even greater risk for substance misuse. Substance use during pregnancy can further impair the individual's level of functioning, and it has also been associated with problems in the social, emotional, and cognitive development of their children. Pregnancy and addiction each require guidance and good medical care. By integrating substance misuse treatment services under the umbrella of their medical care, clinics facilitate timely access to care, as well as help break the stigma associated with substance misuse. Our program offers a comprehensive and multidisciplinary approach to support pregnant individuals with SUDs. Interventions include support, education, case management, and mental health counseling. By providing optimal prenatal care early on, individuals can receive the treatment that they need so that they can achieve physical and emotional stability once the baby arrives, which ultimately has better outcomes for the parent and child's health and wellbeing.

RESUMO

Substance misuse is a pressing public health concern, especially among emerging adults, with implications for psychological health and overall well-being. This cross-sectional study investigates the mediating roles of self-compassion and subjective well-being in the relationship between psychological flexibility and substance misuse among Turkish college students. The study included 445 emerging adults enrolled at a state university in Türkiye. University participants were recruited via convenience sampling using snowball methods. Data were collected using self-report scales. The sample was 69% female (n = 307) and 31% male (n = 138) and ranged in age from 18 to 26 years (M = 20.85, SD = 1.35). In the study, Pearson product-moment correlation analysis was conducted to examine the relationships between the variables and then the serial mediation model was tested. The findings have revealed that psychological flexibility significantly predicts substance misuse, subjective well-being, and self-compassion. Additionally, the study identifies self-compassion as a mediator in the relationship between psychological flexibility and subjective well-being. While self-compassion contributes significantly to well-being, it does not explain the impact of psychological flexibility on substance misuse. Furthermore, subjective well-being also appears to be a mediator in the relationship between psychological flexibility and substance misuse, emphasizing its potential significance in reducing the likelihood of resorting substance misuse. Overall, the study contributes to understanding the pivotal role of self-compassion and psychological flexibility in fostering well-being and preventing substance misuse in the college setting.

RESUMO

Focusing on the understudied question of substance misuse among suicide bereaved adults we investigated patterns of binge drinking and non-prescribed drug use among a recently bereaved sample (n = 1,132). Comparing our respondents to the non-bereaved, those in the 2022 National Survey of Drug Use and Health (n = 71,369), we did not find heightened problematical substance misuses among our respondents. With t-tests and multiple regression analyses we examined whether binge drinkers and non-prescribed drug users had heightened levels of grief difficulties, PTSD, self-blaming and depression compared to others not bingeing or using non-prescribed drugs. Results showed binge drinkers had more of all these grieving problems when important confounding variables were also considered. Analysis of the demographic correlates of bingeing showed them dimly aware of their own additional grieving and substance misusing problems. Since 75% indicated being under the care of counseling professionals, this represents an important opportunity for psycho-educational helping.

RESUMO

BACKGROUND: Midlife adults are experiencing a crisis of deaths of despair (i.e. deaths from suicide, drug overdose, and alcohol-related liver disease). We tested the hypothesis that a syndrome of despair-related maladies at midlife is preceded by psychopathology during adolescence. METHODS: Participants are members of a representative cohort of 1037 individuals born in Dunedin, New Zealand in 1972-73 and followed to age 45 years, with 94% retention. Adolescent mental disorders were assessed in three diagnostic assessments at ages 11, 13, and 15 years. Indicators of despair-related maladies across four domains - suicidality, substance misuse, sleep problems, and pain - were assessed at age 45 using multi-modal measures including self-report, informant-report, and national register data. RESULTS: We identified and validated a syndrome of despair-related maladies at midlife involving suicidality, substance misuse, sleep problems, and pain. Adults who exhibited a more severe syndrome of despair-related maladies at midlife tended to have had early-onset emotional and behavioral disorders [ß = 0.23, 95% CI (0.16-0.30), p < 0.001], even after adjusting for sex, childhood SES, and childhood IQ. A more pronounced midlife despair syndrome was observed among adults who, as adolescents, were diagnosed with a greater number of mental disorders [ß = 0.26, 95% CI (0.19-0.33), p < 0.001]. Tests of diagnostic specificity revealed that associations generalized across different adolescent mental disorders. CONCLUSIONS: Midlife adults who exhibited a more severe syndrome of despair-related maladies tended to have had psychopathology as adolescents. Prevention and treatment of adolescent psychopathology may mitigate despair-related maladies at midlife and ultimately reduce deaths of despair.

RESUMO

Clinical and preclinical studies have identified immunosuppressive effects of nicotine, with potential implications for treating nicotine addiction. Here we review how nicotine can regulate microglia, the resident macrophages in the brain, and corresponding effects of nicotine on neuroimmune signaling. There is significant evidence that activation of α7 nicotinic acetylcholine receptors (nAChRs) on microglia can trigger an anti-inflammatory cascade that alters microglial polarization and activity, cytokine release, and intracellular calcium concentrations, leading to neuroprotection. These anti-inflammatory effects of nicotine-dependent α7 nAChR signaling are lost during withdrawal, suggesting that neuroimmune signaling is potentiated during abstinence, and thus, heightened microglial activity may drive circuit disruption that contributes to withdrawal symptoms and hyperkatifeia. In sum, the clinical literature has highlighted immunomodulatory effects of nicotine and the potential for anti-inflammatory compounds to treat addiction. The preclinical literature investigating the underlying mechanisms points to a role of microglial engagement in the circuit dysregulation and behavioral changes that occur during nicotine addiction and withdrawal, driven, at least in part, by activation of α7 nAChRs on microglia. Specifically targeting microglial signaling may help alleviate withdrawal symptoms in people with nicotine dependence and help to promote abstinence.

RESUMO

This Special Issue (SI) of Preventive Medicine is the 10th in a series on behavior change, health, and health disparities. This issue focuses on Contingency Management (CM), a highly efficacious behavior-change intervention for substance use disorders (SUDs) and other behavioral health conditions wherein patients receive material incentives (e.g., vouchers exchangeable for retail items) contingent on objectively verified behavior change. Despite substantial support for its efficacy, CM remains largely unavailable in U.S. community SUD treatment facilities and other healthcare settings. This is especially concerning regarding stimulant use disorder for which CM is the only reliably efficacious intervention in controlled studies and yet is unavailable to the vast majority of those in need. This SI details recent promising developments in efforts to surmount longstanding implementation obstacles while also detailing other promising advances from meta-analyses and controlled trials examining CM's efficacy in treating other difficult-to-treat problems including smoking among pregnant women and mothers of young children as well among those as those experiencing homelessness and alcohol use disorder, the promise of digital CM, and a potential new application in promoting adherence with SUD medications.

RESUMO

Objective: Adults with asthma have a higher prevalence of substance use. However, knowledge is scarce regarding the associations between adults with asthma and tobacco use, substance use, and substance misuse. This study aimed to use national samples of United States adults to assess the comprehensive use and misuse of substances in adults with asthma.Method: This cross-sectional study comprised data drawn from the 2015 to 2019 National Survey on Drug Use and Health. Weighted logistic regressions were used to measure the associations of asthma status (lifetime and current) with last month's tobacco use; substance use (alcohol, marijuana, cocaine, crack, heroin, hallucinogens, inhalants); and substance misuse (pain relievers, tranquilizers, stimulants, sedatives). All regression models were controlled for sociodemographic characteristics, comorbidity, last-month serious psychological distress, and co-substance use and misuse. Results: Adults with lifetime asthma (Nweighted = 115,600,887) were less likely to use cigarettes, cigars, smokeless tobacco, inhalants, and polyuse of any substance. In contrast, adults with current asthma (Nweighted = 765,096,31) were more likely to use pipe tobacco, cocaine, non-prescribed tranquilizers, and less likely to use polytobacco products. Adults with lifetime asthma were associated with fewer last-month tobacco and inhalant use than those without lifetime asthma. However, adults with current asthma were associated with greater last month's pipe tobacco, cocaine, and non-prescribed tranquilizers. Conclusion: Thus, further longitudinal studies are recommended among adults with asthma to effectively design tailored treatment and prevention interventions.

RESUMO

BACKGROUND: Prenatal alcohol exposure (PAE) can result in a range of adverse neonatal outcomes, including Fetal Alcohol Spectrum Disorder (FASD). This systematic review and meta-analysis sought to investigate the effectiveness of brief interventions (BIs) in eliminating or reducing 1) alcohol consumption during pregnancy; and 2) PAE-related adverse neonatal outcomes; and 3) cost-effectiveness of BIs. METHOD: We conducted a systematic literature search for original controlled studies (randomized control trials (RCTs); quasi-experimental) in any setting, published from 1987 to 2021. The comparison group was no/minimal intervention, where a measure of alcohol consumption was reported. Studies were critically appraised using the Centre for Evidence-based Medicine Oxford critical appraisal tool for RCTs (1). The certainty in the evidence for each outcome was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) (2). Meta-analysis of continuous and binary estimates of effect-size for similar outcome measures for BIs versus control groups were pooled and reported as mean difference (MD) Hedges' g and odds ratios (ORs), respectively. RESULTS: In total, 26 studies, all from high income countries, met inclusion criteria. Alcohol abstinence outcome available in 12 studies (n = 2620) found modest effects in favor of BIs conditions by increasing the odds of abstinence by 56% (OR = 1.56, 95% confidence interval (CI) = 1.15-2.13, I2 = 46.75%; p = 0.04). BIs effects for reduction in mean drinks/week (Cohen's d = - 0.21, 95%CI = - 0.78 to 0.36; p = 0.08) and AUDIT scores (g = 0.10, 95%CI = - 0.06 to 0.26; p = 0.17) were not statistically significant. Among seven studies (n = 740) reporting neonatal outcomes, BI receipt was associated with a modest and significant reduction in preterm birth (OR = 0.67, 95% CI = 0.46-0.98, I2 = 0.00%; p = 0.58). No statistically significant differences were observed for mean birthweight or lower likelihood of low birth weight (LBW). Certainty in the evidence was rated as 'low'. No eligible studies were found on cost-effectiveness of BIs. CONCLUSION: BIs are moderately effective in increasing abstinence during pregnancy and preventing preterm birth. More studies on the effectiveness of BIs are needed from low- and middle-income countries, as well as with younger mothers and with a broader range of ethnic groups.

RESUMO

PURPOSE: We aimed to describe the current literature concerning propofol misuse in medical professionals, specifically relating to the individual demographics of those misusing propofol and the outcomes of propofol misuse. METHODS: We conducted a retrospective scoping review of the literature using a modified PRISMA approach. We used MEDLINE, EMBASE, and PsycINFO databases to identify relevant studies based on search terms. Studies describing individual medical professionals misusing propofol were included. RESULTS: Twenty-four articles describing 88 individual cases of propofol misuse were included for data charting and analysis. Anesthesiologists and certified registered nurse anesthetists were most commonly identified. Death was a common method of identification of misuse, while rehabilitation and death were common final outcomes associated with propofol misuse. CONCLUSIONS: Despite knowledge of the pharmacokinetic and pharmacodynamic properties of propofol by those misusing this medication, death was a common outcome reported in the literature. Data related to long-term outcomes including re-entry to clinical practice or success of rehabilitation were limited.


RéSUMé: OBJECTIF: Nous avons cherché à décrire la littérature actuelle concernant l'abus de propofol chez les professionnels de la santé, en particulier en ce qui concerne les données démographiques individuelles de ceux qui abusent du propofol et les issues d'un tel abus. MéTHODE: Nous avons réalisé une étude de portée rétrospective de la littérature à l'aide d'une approche PRISMA modifiée. Nous avons utilisé les bases de données MEDLINE, EMBASE et PsycINFO pour identifier les études pertinentes en fonction des termes de recherche. Les études décrivant des professionnels de la santé abusant du propofol ont été incluses. RéSULTATS: Vingt-quatre articles décrivant 88 cas individuels d'abus de propofol ont été inclus pour la cartographie et l'analyse des données. Les anesthésiologistes et les infirmières anesthésistes autorisées certifiées ont été le plus souvent identifiés. La mort était une méthode courante d'identification de l'abus, tandis que la réhabilitation et la mort étaient des issues finales fréquemment associées à l'abus de propofol. CONCLUSION: Malgré la connaissance des propriétés pharmacocinétiques et pharmacodynamiques du propofol par ceux qui abusent de ce médicament, le décès était une issue fréquente rapportée dans la littérature. Les données relatives aux issues à long terme, y compris le retour à la pratique clinique ou le succès de la réhabilitation, étaient limitées.

RESUMO

Background: The last decade has witnessed a surge of findings implicating neuroinflammatory processes as pivotal players in substance use disorders. The directionality of effects began with the expectation that the neuroinflammation associated with prolonged substance misuse contributes to long-term neuropathological consequences. As the literature grew, however, it became evident that the interactions between neuroinflammatory processes and alcohol and drug intake were reciprocal and part of a pernicious cycle in which disease-relevant signaling pathways contributed to an escalation of drug intake, provoking further inflammation-signaling and thereby exacerbating the neuropathological effects of drug misuse.Objectives: The goal of this review and its associated special issue is to provide an overview of the emergent findings relevant to understanding these reciprocal interactions. The review highlights the importance of preclinical and clinical studies in testing and validation of immunotherapeutics as viable targets for curtailing substance use and misuse, with a focus on alcohol misuse.Methods: A narrative review of the literature on drug and neuroinflammation was conducted, as well as articles published in this Special Issue on Alcohol- and Drug-induced Neuroinflammation: Insights from Pre-clinical Models and Clinical Research.Results: We argue that (a) demographic variables and genetic background contribute unique sensitivity to drug-related neuroinflammation; (b) co-morbidities between substance use disorders and affect dysfunction may share common inflammation-related signatures that predict the efficacy of immunotherapeutic drugs; and (c) examination of polydrug interactions with neuroinflammation is a critical area where greater research emphasis is needed.Conclusions: This review provides an accessible and example-driven review of the relationship between drug misuse, neuroinflammatory processes, and their resultant neuropathological outcomes.

RESUMO

BACKGROUND: Significant heterogeneity exists among people who use drugs (PWUD). We identify distinct profiles of syringe service program (SSP) clients to (a) evaluate differential risk factors across subgroups and (b) inform harm reduction programming. METHODS: Latent class analysis (LCA) was applied to identify subgroups of participants (N = 3418) in a SSP in Columbus, Ohio, from 2019 to 2021. Demographics (age, sex, race/ethnicity, sexual orientation, housing status) and drug use characteristics (substance[s] used, syringe gauge, needle length, using alone, mixing drugs, sharing supplies, reducing use, self-reported perceptions on the impact of use, and treatment/support resources) were used as indicators to define latent classes. A five-class LCA model was developed, and logistic regression was then employed to compare risk factors at program initiation and at follow-up visits between latent classes. RESULTS: Five latent classes were identified: (1) heterosexual males using opioids/stimulants with housing instability and limited resources for treatment/support (16.1%), (2) heterosexual individuals using opioids with stable housing and resources for treatment/support (33.1%), (3) individuals using methamphetamine (12.4%), (4) young white individuals using opioids/methamphetamine (20.5%), and (5) females using opioids/cocaine (17.9%). Class 2 served as the reference group for logistic regression models, and at the time of entry, class 1 was more likely to report history of substance use treatment, overdose, HCV, sharing supplies, and mixing drugs, with persistently higher odds of sharing supplies and mixing drugs at follow-up. Class 3 was more likely to report history of overdose, sharing supplies, and mixing drugs, but outcomes at follow-up were comparable. Class 4 was the least likely to report history of overdose, HCV, and mixing drugs, but the most likely to report HIV. Class 5 was more likely to report history of substance use treatment, overdose, HCV, sharing supplies, and mixing drugs at entry, and higher reports of accessing substance use treatment and testing positive for HCV persisted at follow-up. CONCLUSIONS: Considerable heterogeneity exists among PWUD, leading to differential risk factors that may persist throughout engagement in harm reduction services. LCA can identify distinct profiles of PWUD accessing services to tailor interventions that address risks, improve outcomes, and mitigate disparities.

RESUMO

Background: Although exposure to potentially traumatic events (PTEs) for Black and Latinx may be comparable or lower than their White counterparts, type of trauma experiences differ such as more interpersonal trauma and violence reported by Black people, who also experience higher rates of PTSD. In this retrospective study, we examined the association between use of particular substances and various PTEs and the race/ethnicity-group differences for this association. Methods: One-hundred seventy-nine participants recruited from an outpatient substance use disorder program from February 2018 to October 2020 completed measures on lifetime trauma history and current/past cocaine, cannabis, and alcohol misuse. Bayesian generalized linear modeling with horseshoe prior was used to predict substance misuse using 17 PTEs, then PTEs were ranked and examined by racial/ethnic group. Results: No PTEs were associated with substance misuse across all four r/e groups. Transportation accident, natural disaster, war exposure, and other stressful events were associated with substance misuse across two or three r/e groups. Notably, the three PTEs involving interpersonal violence in our study (weapon assault, physical assault, and sexual assault) were only associated with substance misuse (posterior probability ≥70%) for Latinx participants. Conclusion: The relational nature of interpersonal/violent traumas may make them particularly salient for Latinx people where interpersonal relationships are prioritized. These types of traumas may also be viewed as an extension of discrimination and exclusion, two longstanding, intractable issues for people of color in the US, making them even more damaging. Furthermore, lack of resources may limit options for coping, resulting in substance use problems.

RESUMO

Background: Opioid misuse is a crisis in the United States, and synthetic opioids such as fentanyl pose risks for overdose and mortality. Individuals who misuse substances commonly seek information and support online due to stigma and legal concerns, and this online networking may provide insight for substance misuse prevention and treatment. We aimed to characterize topics in substance-misuse related discourse among members of an online fentanyl community. Method: We investigated posts on a fentanyl-specific forum on the platform Reddit to identify emergent substance misuse-related themes potentially indicative of heightened risk for overdose and other adverse health outcomes. We analyzed 27 posts and 338 comments with a qualitative codebook established using a subset of user posts via inductive and deductive methods. Posts and comments were independently reviewed by two coders with a third coder resolving discrepancies. The top 200 subreddits with the most activity by r/fentanyl members were also inductively analyzed to understand interests of r/fentanyl users. Results: Functional/quality of life impairments due to substance misuse (29%) was the most commonly occurring theme, followed by polysubstance use (27%) and tolerance/dependence/withdrawal (20%). Additional themes included drug identification with photos, substances cut with other drugs, injection drugs, and past overdoses. Media-focused subreddits and other drug focused communities were among the communities most often followed by r/fentanyl users. Conclusion: Themes closely align with DSM-V substance use disorder symptoms for fentanyl and other substances. High involvement in media-focused subreddits and other substance-misuse-related communities suggests digital platforms as acceptable for overdose prevention and recovery support interventions.

RESUMO

Background: Substance use disorder (SUD) is a significant issue in the United States, characterized by chronic relapse following periods of abstinence. One of the primary precursors to relapse is craving. Findings from several studies have shown a negative association between trait mindfulness and craving in clinical samples; however, further research is needed to understand mechanisms underlying this relationship. Purpose/Objectives: The current study assessed thought suppression as a partial mediator of the relationship between trait mindfulness and craving. Methods: The current study used data from a previous randomized controlled trial of adults (N = 244) enrolled in community-based treatment for substance use disorder (SUD). Results: Analyses showed a significant moderate positive association between thought suppression and craving, a significant moderate negative association between thought suppression and trait mindfulness, and a significant moderate negative association between trait mindfulness and craving. Subsequent analyses confirmed a partial mediating role of thought suppression in the relationship between trait mindfulness and craving, indicating the inverse relationship between trait mindfulness and craving was partially explained by thought suppression. Conclusions/importance: These findings may inform treatment for SUD. Specifically, targeting thought suppression through mindfulness-based treatment approaches may be a mechanism through which craving can be reduced.

RESUMO

Background: Efforts to increase the availability of Medication Assisted Treatment for alcohol use disorder (AUD) and opioid use disorder (OUD) may be futile if patients lack motivation for recovery and are unwilling to seek treatment. Objectives: In this cross-sectional, online survey, we used the Extended Parallel Process Model (EPPM) to assess how participants at risk of AUD or OUD react to their perceived threat and assess their response to pharmacotherapy as a potential treatment. EPPM constructs were assessed using the Risk Based Diagnosis Scale. Descriptive statistics measure the proportion of treated vs untreated participants. Untreated participants were sorted into one of three groups categorizing perceived threat - low threat appraisal, and danger or fear control. Results: Of 411 total responses, most (n = 293[71.29%]) sorted into the AUD cohort and 118(28.71%) into the OUD cohort. Overall, 104(25.30%) had received treatment and 307(74.70%) didn't. Within the OUD cohort, there were 67 untreated participants - 16(23.88%) exhibited low threat appraisal, 13(19.40%) were likely to undergo fear control, and 38(56.72%) were likely to undergo danger control. Within the AUD cohort, there were 240 untreated participants - 75(31.25%) exhibited low threat appraisal, 100(41.67%) were likely to experience fear control, and 65(27.08%) were likely to experience danger control. Participants in the OUD cohort were more likely to undergo danger control than those in the AUD cohort (χ2 = 19.26, p < 0.05). Conclusions: This study identified perceived threat and efficacy when an individual was at risk of a SUD, but more insight into potential early interventions is needed - particularly in those individuals with polysubstance use disorder.

RESUMO

BACKGROUND: Substance misuse teaching within the undergraduate medical curriculum has been underrepresented compared to more traditional medical topics. In response several national curriculum reviews such as the most recent UK department of health initiative (DOH) have identified deficiencies in substance misuse education and have suggested curriculum interventions for local faculties to implement. The student perspective however has largely been muted during this process and this study aims to explore this using a constructivist grounded theory approach. METHODS: Eleven final year and intercalating medical students across three separate focus groups participated in this study over a three-month period commencing from March 2018. Time between the audio recorded focus groups allowed for a parallel process of data collection and analysis into more focussed codes and categories to occur, consistent with the grounded theory approach. The qualitative study took place in a single medical school in the UK. RESULTS: Medical students had a common consensus that substance misuse education was an underperforming subject in their curriculum, from limited teaching hours to curriculum design and organisational problems. Students identified an alternative curriculum is required to not only prepare students for their future clinical duties but also their own personal lives. Students highlighted this proximity to a 'dangerous world' where exposure to substance misuse risks were faced daily. This exposure also provided a source of informal learning experiences which students deemed as being potentially unbalanced and even dangerous. Students also identified unique barriers to curriculum change with reference to a lack of openness due to the impacts of disclosure in substance misuse. CONCLUSION: Large scale curriculum initiatives appear to correspond to the student voice obtained in this study, providing backing for the implementation of a co-ordinated substance misuse curriculum within medical schools. The student voice however provides an alternative lens by outlining how substance misuse pervades into students' lives and how informal learning is a largely underestimated hidden source of learning with more dangers than benefits. This together with the identification of further barriers to curriculum change, provide space for medical faculties to incorporate and work with students to facilitate local level curriculum changes relating to substance misuse education.
