History Of Substance Use Disorder Research Articles

The trajectory of substance use disorder among people formerly in foster care: A survival analysis.

Substance use disorder (SUD) represents a significant public health challenge, especially among individuals who have faced early life adversities. Foster care aims to provide a supportive environment for children; however, the relationship between a history of foster care and SUD development remains unclear. This study aims to examine the likelihood of developing SUD among individuals with a history of foster care, who have used substances during their lifetime, compared to those raised by biological parents. Using data from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III), we analyzed the prevalence of social demographics and clinical variables among individuals who have used alcohol, nicotine, or cannabis. We calculated the probabilities of developing SUD for each factor, including exposure to foster care. Various covariates that could impact SUD occurrence were also assessed. The duration from initial substance use to SUD onset was calculated for both groups. Survival analysis curves were generated for each substance to depict the probability of SUD development over time. Our analysis revealed that foster care may act as a protective factor against Cannabis Use Disorder (CUD), with a hazard ratio of 0.25 (95% CI [0.07, 0.88]). No significant associations were found with Alcohol Use Disorder (AUD) or Nicotine Use Disorder (NUD). Both foster and non-foster care groups exhibited higher probabilities of developing NUD compared to the general population. For cannabis users, the probability of developing CUD stabilizes after approximately 10 years. Family history of SUD and clinical predictors such as mood disorders consistently showed significant associations across all substance groups, highlighting their importance in SUD development. Our findings suggest that foster care may offer some protective benefits, particularly against CUD, emphasizing the need for further research into its protective factors and the development of targeted interventions to reduce SUD prevalence in this population.

Health information exchange and 42 CFR part two: Incorporating the voice of people with histories of substance use disorder

IntroductionWe set out to understand patient attitudes and concerns about sharing information about substance use disorder (SUD) history through a Health Information Exchange (HIE), in the context of 42 CFR Part 2. MethodsThe study conducted semi-structured qualitative interviews of people with SUD history, recruited through an association of recovery communities in Rhode Island. Interviews were recorded and transcribed. Two Research Assistants coded the interviews using Atlas.ti™ in consultation with the principal investigator. Each first coded a sample of interviews independently. The team then discussed the coding and agreed on broad coding categories. The team met regularly to discuss emerging constructs and agree on a detailed coding schema. We came to consensus on broad themes and selected illustrative quotations. Interpretation was pragmatic, focusing on the nature and consequences of participants' experiences, and their wishes and intentions with respect to information sharing. ResultsOf 27 respondents, all but three reported negative experiences with health care providers because of current or former SUD, ranging from judgmental to neglectful or inappropriate treatment, to disparagement and abuse. With few exceptions, they would not consider sharing their SUD history through an HIE without specific, revocable control over which individual providers could receive the information. ConclusionsRespondents' requirements are consistent with the legal requirements of 42 CFR Part 2. Implementing Part 2 compliant HIE will require overcoming substantial technical and procedural challenges.

Identifying Pregnant Patients With Suspected Intimate Partner Violence.

Intimate partner violence (IPV) is the leading cause of death in pregnant women. Although it can be difficult to identify patients experiencing IPV, injuries to the head, neck, or face due to an assault are known to correlate with intentional injury. The objective of this study is to assess the contemporary burden of IPV in pregnancy and describe the patient characteristics. The National Inpatient Sample was queried for all pregnant women between January 2016 and December 2019. Patients were divided into two groups: suspected IPV (SIPV) and no-SIPV groups. We defined SIPV as any pregnant patient with an identified head, neck, or face injuries categorized as intentional assault. Multivariable logistic regression analysis was performed to assess the association between SIPV and variables of interest. A total of 28,540 pregnant patients presented with traumatic injuries with 530 (.02%) identified as SIPV. Suspected IPV patients were younger (25 vs 27 years, P = .012), more likely to be of Black race (46% vs 28%, P = .002), more likely to be in the lowest income quartile (51% vs 38%, P = .031), less likely to have private insurance (12% vs 34%, P < .001), and have higher rates of substance use disorder (35% vs 18%, P < .001). Black race and history of substance use disorder were associated with increased odds of SIPV-related injuries (odds ratio [OR]: 2.01, interquartile range [IQR]: 1.27-3.16, P = .003 and OR: 2.30, IQR 1.54-3.43, P < .001, respectively). Our results suggest that there are significant racial and socioeconomic disparities in potential risk for IPV during pregnancy.

"Before medically advised" departure from hospital and subsequent drug overdose: a population-based cohort study.

A substantial number of hospital admissions end in patient-initiated departure before medical treatment is complete. Whether "before medically advised" (BMA) discharge increases the risk of subsequent drug overdose remains uncertain. We performed a retrospective cohort study using administrative health data from a 20% random sample of residents of British Columbia, Canada. We focused on nonelective, nonobstetric hospital stays occurring between 2015 and 2019. We used survival analysis to compare the rate of fatal or nonfatal illicit drug overdose in the first 30 days after BMA discharge versus the rate after physician-advised discharge. Overall, 6440 of 189 808 (3.4%) hospital stays ended in BMA discharge. Among 820 overdoses occurring in the first 30 days after any hospital discharge, 755 (92%) involved patients with a history of substance use disorder. Unadjusted overdose rates were 10-fold higher after BMA discharge than after physician-advised discharge, and BMA discharge was associated with subsequent overdose even after adjustment for potential confounders (crude incidence, 2.8% v. 0.3%; adjusted hazard ratio [HR] 1.58; 95% confidence interval [CI] 1.31-1.89). Before medically advised discharge was associated with increases in subsequent emergency department visits (adjusted HR 1.92; 95% CI 1.83-2.02) and unplanned hospital readmissions (adjusted HR 2.07; 95% CI 1.96-2.19), but there was no significant association with the uncommon outcomes of fatal overdose and all-cause mortality. Before medically advised departure is associated with an increased risk of drug overdose in the first 30 days after discharge. Improved treatment of substance use disorder, expanded access to overdose prevention services, and new means of postdeparture outreach should be explored to reduce this risk.

B - 80 The Long-Term Memory Sign in Adults Referred for Neuropsychological Evaluation

Abstract Objective We investigated the clinical utility of the newly described long-term memory (LTM) sign in adults referred for neuropsychological evaluation. Individuals with dementia often report short-term episodic memory decline or no memory decline, but rarely report long-term episodic memory decline. The LTM sign refers to patient self-report of long-term episodic memory decline, that is equivalent to/or greater than, subjective short-term episodic memory decline. Method The LTM sign was endorsed on a pre-visit intake form and established during clinical interview in 568 patients (M age = 63, SD = 14.3) referred for neuropsychological evaluation at a large medical center in the Northwest United States. Results In our sample of 568 patients, 79 (14%) reported the LTM sign. In 79 patients with the LTM sign, 45 were diagnosed with a primary psychiatric disorder (57%), 23 were diagnosed with mild neurocognitive disorder (29%), seven had no cognitive or psychiatric diagnosis (9%), and four had dementia (5%). The LTM sign was most common in those with a history of trauma in childhood or adolescence (52/79, 66%) and substance use disorders (50/79, 63%). Conclusions The LTM sign was rare in dementia, but common in those with a current psychiatric diagnosis. These findings support the literature on episodic memory decline in dementia populations and suggests that encoding of early memories and/or retrieval of old memories is negatively impacted by a current psychiatric disorder, traumatic events in childhood and adolescence, and lifetime history of substance use disorder. The LTM sign is a valuable addition to the clinical interview of neuropsychological patients.

Nicotine dependence and incident psychiatric disorders: prospective evidence from US national study.

We examined the prospective associations between nicotine dependence and the likelihood of psychiatric and substance use disorders in the general adult population. Participants came from a nationally representative sample of US adults aged 18 years or older, who were interviewed 3 years apart in the National Epidemiologic Survey on Alcohol and Related Conditions (Wave 1, 2001-2002; Wave 2, 2004-2005). The primary analyses were limited to 32,671 respondents (13,751 male (47.9% weighted); mean age of 45 years (SD = 0.18)) who were interviewed in both waves. We used multiple regression and propensity score matching (PSM) to estimate the strength of independent associations between nicotine dependence related to the use of tobacco products at Wave 1 and incident psychiatric disorders at Wave 2. Psychiatric disorders were measured with a structured interview (Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV). All analyses adjusted for multiple potential confounders, including childhood (family history of substance use disorders, parental loss, vulnerable family environment), early-adolescence (self-esteem, social deviance, conduct disorder), late-adolescence (education, personality and psychiatric disorders), adulthood (divorce, stressful life events, social deviance, quality of life, history of alcohol or other substance use disorder), and sociodemographic factors. Multiple regression analysis and PSM converged in indicating that nicotine dependence was associated with significantly increased incidence of any psychiatric disorder (OR = 1.39(95%CI:1.20;1.60)), including substance use disorders (OR = 1.91(95%CI:1.47;2.47)), and anxiety disorders (OR = 1.31(95%CI:1.06;1.62)). Population Attributable Risk Proportions were substantial, ranging from 12.5%(95%CI:8.10;17.0) for any psychiatric disorder to 33.3%(95%CI:18.7;48.0) for any other drug use disorder. Supplementary analyses also indicated significant associations between nicotine dependence and persistence of psychiatric and substance use disorders among patients having a disorder at Wave 1. In the general adult population, nicotine dependence is associated with an increased likelihood for several psychiatric and substance use disorders. Given its high prevalence, these findings have important public health implications.

Sex-specific differences in brain activity dynamics of youth with a family history of substance use disorder.

An individual's risk of substance use disorder (SUD) is shaped by a complex interplay of potent biosocial factors. Current neurodevelopmental models posit vulnerability to SUD in youth is due to an overreactive reward system and reduced inhibitory control. Having a family history of SUD is a particularly strong risk factor, yet few studies have explored its impact on brain function and structure prior to substance exposure. Herein, we utilized a network control theory approach to quantify sex-specific differences in brain activity dynamics in youth with and without a family history of SUD, drawn from a large cohort of substance-naïve youth from the Adolescent Brain Cognitive Development Study. We summarize brain dynamics by calculating transition energy, which probes the ease with which a whole brain, region or network drives the brain towards a specific spatial pattern of activation (i.e., brain state). Our findings reveal that a family history of SUD is associated with alterations in the brain's dynamics wherein: i) independent of sex, certain regions' transition energies are higher in those with a family history of SUD and ii) there exist sex-specific differences in SUD family history groups at multiple levels of transition energy (global, network, and regional). Family history-by-sex effects reveal that energetic demand is increased in females with a family history of SUD and decreased in males with a family history of SUD, compared to their same-sex counterparts with no SUD family history. Specifically, we localize these effects to higher energetic demands of the default mode network in females with a family history of SUD and lower energetic demands of attention networks in males with a family history of SUD. These results suggest a family history of SUD may increase reward saliency in males and decrease efficiency of top-down inhibitory control in females. This work could be used to inform personalized intervention strategies that may target differing cognitive mechanisms that predispose individuals to the development of SUD.

State Mandates On Naloxone Coprescribing Associated With Short-Term Increase In Naloxone Codispensing.

In the midst of the opioid crisis in the US, efforts to mitigate overdose risks have become paramount, leading some states to introduce mandates for coprescribing the life-saving overdose reversal drug naloxone. These mandates were designed to specifically address people receiving opioid analgesics who had an elevated risk for overdose. This included people receiving high opioid dosages, those concurrently using benzodiazepines, or those with a history of substance use disorder or overdose. Using a nationally representative, multipayer cohort of patients receiving prescription opioids, we investigated how naloxone codispensing rates changed at the state level from 2016 to 2021 among patients with an elevated risk for overdose. Then we used controlled interrupted time series analyses to assess mandates' longitudinal impact on naloxone codispensing in ten states that implemented mandates. We observed an immediate and significant increase in the naloxone codispensing rates in eight states after the implementation of mandates. Nevertheless, in five of these states, the codispensing rates exhibited a subsequent downward trend after the initial increase. State mandates show potential for improving naloxone codispensing; however, mandates alone might not be adequate for sustained change. Further research is needed to identify strategies complementing and enhancing the impact of mandates in combating the overdose crisis.

W121 - Earlier Substance Use and Differential Rates by Substance Class for Youth With Combined Externalizing Disorders and Family History of Substance Use Disorders

W121 - Earlier Substance Use and Differential Rates by Substance Class for Youth With Combined Externalizing Disorders and Family History of Substance Use Disorders

The Epidemic of Congenital Syphilis in the Indigenous and Rural Populations of South Dakota.

From 2020 to 2023, South Dakota witnessed a substantial increase in cases of congenital syphilis (CS), with the highest rates identified in rural and Native American (NA) communities. Here, we discuss 3 severe cases of CS in premature infants born to NA individuals and communities in South Dakota with poor access to prenatal care. The infants in these 3 cases presented with varying clinical conditions, including respiratory failure, persistent pulmonary hypertension of the newborn, severe direct hyperbilirubinemia, feeding intolerance, and necrotizing enterocolitis. Lack of prenatal care and other systemic health disparities likely contributed to the increased disease burden. For NA communities, rurality, limited resources, systemic racism, historical trauma, and lack of trust in medical institutions likely contribute to inadequate prenatal care. All 3 of these cases also occurred in pregnant people with a present or history of substance use disorders, which may have led to further hesitancy to seek care because of fear of prosecution. To combat the rising number of syphilis and CS cases, we advocate for new and continued outreach that provides education about and testing for sexually transmitted diseases to NA and rural populations, increased care coordination, the integration of point-of-care testing and treatment strategies in lower resource centers, and legislative allocation of additional resources to engage pregnant people with or at risk for substance use disorders.

Young adults with a history of substance use disorder experienced more negative mental health, social and economic outcomes during the COVID-19 pandemic period.

For young adults, the disruptions brought by the COVID-19 pandemic to work, social relationships and health-care probably impacted normative life stage transitions. Disaster research shows that negative effects of these events can persist for years after the acute crisis ends. Pandemic-related disruptions may have been especially consequential for young adults with a history of substance use disorder (SUD). The current work aimed to measure the broad impact of the COVID-19 pandemic on young adults with and without a history of SUD. Data were from a longitudinal panel of n = 4407 young adults across the United States surveyed repeatedly from 2014 to 2019 (aged 19-26 years, pre-pandemic) and again in 2021 (aged 28 years, mid-pandemic). We fitted multi-level models to understand the association between SUD history and pandemic outcomes, controlling for potential confounders (socio-demographic and health measures). Outcomes included overall life disruption; mental health, social and economic impacts; substance use; and physical health. Young adults with a history of SUD reported greater life disruption (standardized β = 0.13-0.15, Ps < 0.015) and negative mental health impacts (standardized β = 0.12-0.14, Ps < 0.012), experienced approximately 20% more work-related stressors (relative risks = 1.18-1.22, Ps < 0.002) and 50% more home-related stressors (relative risks = 1.40-1.51, Ps < 0.001), and had two to three times the odds of increased substance use during the pandemic (odds ratios = 2.07-3.23, Ps < 0.001). Findings generally did not differ between those with a recent SUD diagnosis and those in recovery from SUD before the pandemic began. United States young adults with a history of substance use disorder (SUD) reported more life disruption and greater negative physical and mental health, social and economic impacts during the COVID mid-pandemic period than young adults with no history of SUD.

Characteristics of Adolescents with and without a Family History of Substance Use Disorder from a Minority Cohort.

Family history (FH+) of substance use disorder (SUD) is an established risk factor for offspring SUD. The extent to which offspring psychological traits or the family environment, each of which may be relevant to familial transmission of SUD risk, vary by FH+ in socioeconomically disadvantaged populations is less clear. We compared the family/social environmental and psychological characteristics of 73 FH+ and 69 FH- youth ages 12-16, from a study of parental criminal justice system involvement in a primarily low-income, minority urban population. A latent profile analysis (LPA) empirically identified groups of subjects with similar psychological characteristics, which were then compared by FH+. FH+ youths were found to have greater mean household size, greater parental psychological aggression, and a higher mean number of adverse childhood experiences, even without considering parental SUD. FH+ individuals had lower report card grades according to parental report and were more likely to have a history of externalizing disorders than FH- individuals. However, FH+ was not significantly associated with many psychological characteristics or with the class membership from the LPA. In conclusion, among a population of low-income, minority urban youth, FH+ was associated with differences in the family environment and only subtle differences in individual psychological characteristics.

Multiple marginalized identities: A qualitative exploration of intersectional perinatal experiences of birthing people of color with substance use disorder in Massachusetts

IntroductionRacial and ethnic inequities persist in receipt of prenatal care, mental health services, and addiction treatment for pregnant and postpartum individuals with substance use disorder (SUD). Further qualitative work is needed to understand the intersectionality of racial and ethnic discrimination, stigma related to substance use, and gender bias on perinatal SUD care from the perspectives of affected individuals. MethodsPeer interviewers conducted semi-structured qualitative interviews with recently pregnant people of color with SUD in Massachusetts to explore the impact of internalized, interpersonal, and structural racism on prenatal, birthing, and postpartum experiences. The study used a thematic analysis to generate the codebook and double coded transcripts, with an overall kappa coefficient of 0.89. Preliminary themes were triangulated with five participants to inform final theme development. ResultsThe study includes 23 participants of diverse racial/ethnic backgrounds: 39% mixed race/ethnicity (including 9% with Native American ancestry), 30% Hispanic or Latinx, 26% Black/African American, 4% Asian. While participants frequently names racial and ethnic discrimination, both interpersonal and structural, as barriers to care, some participants attributed poor experiences to other marginalized identities and experiences, such as having a SUD. Three unique themes emerged from the participants' experiences: 1) Participants of color faced increased scrutiny and mistrust from clinicians and treatment programs; 2) Greater self-advocacy was required from individuals of color to counteract stereotypes and stigma; 3) Experiences related to SUD history and pregnancy status intersected with racism and gender bias to create distinct forms of discrimination. ConclusionPregnant and postpartum people of color affected by perinatal SUD faced pervasive mistrust and unequal standards of care from mostly white healthcare staff and treatment spaces, which negatively impacted their treatment access, addiction medication receipt, postpartum pain management, and ability to retain custody of their children. Key clinical interventions and policy changes identified by participants for antiracist action include personalizing anesthetic plans for adequate peripartum pain control, minimizing reproductive injustices in contraceptive counseling, and addressing misuse of toxicology testing to mitigate inequitable Child Protective Services (CPS) involvement and custody loss.

Changes in Emergency Department Utilization in Vulnerable Populations After COVID-19 Shelter-in-Place Orders.

This study aims to compare emergency department (ED) utilization and admission rates for patients with a history of mental health (MH) disorders, substance use disorders (SUDs), and social determinants of health (SDOH) before and after implementing COVID-19shelter-in-place (SIP) orders. This was a retrospective, multicenter study leveraging electronic medical record (EMR) data from 20 EDs across a large Midwest integrated healthcare system from 5/2/2019 to 12/31/2019 (pre-SIP) and from 5/2/2020 to 12/31/2020 (post-SIP). Diagnoses were documented in the patient's medical records. Poisson and logistic regression models were used to evaluate ED utilization and admission rate changes. A total of 871,020 ED encounters from 487,028 unique patients were captured. Overall, 2,572 (0.53%) patients had a documented Z code for SDOH. Patients with previously diagnosed MH disorders or SUDs were more likely to seek ED care after the SIP orders were implemented (risk ratio (RR): 1.20, 95% confidence interval (CI): 1.18-1.22, p<0.001), as were patients with SDOH (RR: 2.37, 95% CI: 2.19-2.55, p<0.001). Patients with both previously diagnosed MHdisorders or SUDs and a documented SDOH had even higher ED utilization (RR: 3.31, 95% CI: 2.83-3.88, p<0.001) than those with either condition alone. Patients with MHdisorders and SUDs (OR: 0.89, 95% CI: 0.86-0.92, p<0.001) or SDOH (OR: 0.67, 95% CI: 0.54-0.83, p<0.001) were less likely to be admitted post-SIP orders, while patients with a history of diseases of physiologic systems were more likely to be admitted. Vulnerable populations with a history of MH disorders,SUDs, and SDOH experienced increased ED utilization but a lower rate of hospital admissions after the implementation of SIP orders. The findings highlight the importance of addressing these needs to mitigate the impact of public health crises on these populations.

Long-COVID impacts taste and olfactory in individuals with substance use disorder: A retrospective cohort study from the TriNetX US Collaborative Networks

Substance use disorder (SUD) exacerbates the impact of Long-COVID, particularly increasing the risk of taste and olfactory disorders. Analyzing retrospective cohort data from TriNetX and over 33 million records (Jan 2020-Dec 2022), this study focused on 1,512,358 participants, revealing that SUD significantly heightens the likelihood of experiencing taste disturbances and anosmia in Long-COVID sufferers. Results indicated that individuals with SUD face a higher incidence of sensory impairments compared to controls, with older adults and women being particularly vulnerable. Smokers with SUD were found to have an increased risk of olfactory and taste dysfunctions. The findings underscore the importance of early screening, diagnosis, and interventions for Long-COVID patients with a history of SUD, suggesting a need for clinicians to monitor for depression and anxiety linked to sensory dysfunction for comprehensive care.

Slicing through silos: Development and evaluation of a hospital-based telehealth hepatitis C virus treatment program

BackgroundThere exist many barriers to hepatitis C virus (HCV) treatment for those with substance use disorder (SUD) or who lack access to routine medical care. A hospital-based telehealth program was developed to provide treatment opportunities for hospitalized patients living with HCV. MethodsThis single site prospective cohort study conducted from July 2022 to March 2023 aimed to measure linkage to care with an HCV clinician and initiation of HCV treatment in hospitalized patients. Patients were assessed in-person by a social worker then seen via telehealth by a clinician who prescribed either glecaprevir/pibrentasvir or sofosbuvir/velpatasvir. Treatment was initiated with pharmacist assistance. The team conducted in-person and/or telephonic outreach during and after hospitalization. Cure was confirmed by sustained virologic response at 12 weeks (SVR12) post-treatment. ResultsA total of 25 patients were enrolled and completed telehealth visits. All patients had a history of SUD and 18 (72 %) were unstably housed. Nineteen patients (76 %) initiated treatment, and 14 (56 %) successfully completed treatment. Twelve patients (48 %) completed post-treatment labs, including two who prematurely discontinued treatment. Eleven patients (44 %) achieved confirmed cure with SVR12. Conclusion: A hospital-based, multidisciplinary telehealth program can be an innovative care model to successfully treat HCV in a difficult-to-treat patient populations.

A Moderated Mediation Model of Age-Related Decline in Selective Executive Functions and Quality of Life in Men with Substance Use Disorder.

It is known from earlier literature that substance use is associated with diminished executive functioning and decreased quality of life (QoL). The study extended this knowledge by assessing whether selective executive function components would mediate the association between age and QoL domains in young men with substance use disorder and whether family history of substance use would moderate these mediated associations. A sample of 212 young inpatient men with substance use disorder (105 positive family history and 107 negative family history of substance use disorder) was selected from drug units/wards of government sector hospitals. The participants with positive family history compared to those with negative family history scored significantly lower on all QoL domains except physical QoL. Mediation analyses revealed that only inhibition but not flexibility mediated the negative association of age with psychological, social, and environmental QoL. Furthermore, family history of substance use moderated all the significant mediated associations with stronger indirect negative associations in participants having a family history of substance use disorder compared to those with no such history. It is concluded that inhibitory control, which is vulnerable to aging, substance use, and family history of substance use, is an important factor related to QoL in young substance abuser men.

Clinical prediction of opioid use disorder in chronic pain patients: a cohort-retrospective study with a pharmacogenetic approach.

Opioids are widely used in chronic non-cancer pain (CNCP) management. However, they remain controversial due to serious risk of causing opioid use disorder (OUD). Our main aim was to develop a predictive model for future clinical translation that include pharmacogenetic markers. An observational study was conducted in 806 pre-screened Spanish CNCP patients, under long-term use of opioids, to compare cases (with OUD, N.=137) with controls (without OUD, N.=669). Mu-opioid receptor 1 (OPRM1, A118G, rs1799971) and catechol-O-methyltransferase (COMT, G472A, rs4680) genetic variants plus cytochrome P450 2D6 (CYP2D6) liver enzyme phenotypes were analyzed. Socio-demographic, clinical and pharmacological outcomes were also registered. A logistic regression model was performed. The model performance and diagnostic accuracy were calculated. OPRM1-AA genotype and CYP2D6 poor and ultrarapid metabolizers together with three other potential predictors: 1) age; 2) work disability; 3) oral morphine equivalent daily dose (MEDD), were selected with a satisfactory diagnostic accuracy (sensitivity: 0.82 and specificity: 0.85), goodness of fit (P=0.87) and discrimination (0.89). Cases were ten-year younger with lower incomes, more sleep disturbances, benzodiazepines use, and history of substance use disorder in front of controls. Functional polymorphisms related to OPRM1 variant and CYP2D6 phenotypes may predict a higher OUD risk. Established risk factors such as young age, elevated MEDD and lower incomes were identified. A predictive model is expected to be implemented in clinical setting among CNCP patients under long-term opioids use.

Triage mistakes in the Psychiatry Emergency Room: do we really know how to rule out organicity?

IntroductionIn Spain and other European countries, patients coming to the emergency room (ER) are usually classified as “organic” or “psychiatric” on arrival, but this may be complicated when psychiatric history is present as the focus can be misplaced (Leeman. IJPM 1975;6(4):544-40; Alam et al. Psychiatr. Clin. North Am. 2017;40(3):425–33).Objectives To describe three cases seen in the psychiatric emergency room (PER) in which triage errors occurred and to review whether it is widespread for psychiatric patients with organic pathology or in need of medical care to be wrongly triaged.Methods We retrospectively reviewed three cases seen in the PER of Hospital Clínic in July 2023 in which triage errors happened. Triage error was considered when patients triaged directly to the PER presented symptoms that either needed medical treatment or required medical clearance before being considered purely psychiatric.ResultsCase 1: A 27-year-old woman with history of depressive syndrome was triaged for a speech disturbance that had occurred fifteen minutes after intercourse. After being evaluated, she was referred to neurology where she was diagnosed with an acute ischaemic stroke in left middle cerebral artery territory, requiring thrombectomy and posterior admission to neurology.Case 2: A 50-year-old man with history of alcohol use disorder was brought to the PER after saying that “he was seeing people doing magic” at home. When evaluated, significant distal tremor, tachycardia and hypertension were observed, being compatible with withdrawal symptoms, so he was transferred to the ER. There he was monitored and treated, finally requiring admission to internal medicine due to persistent symptoms.Case 3: A 26-year-old man with history of substance use disorder was triaged for loss of consciousness and “spasms”. After evaluation, he was transferred to the ER, where organic screening was carried out, being oriented as a probable tonic-clonic seizure and discharged with outpatient follow-up.ConclusionsThe cases presented are instances in which somatic diseases in patients pre-labelled with psychiatric histories were wrongly assumed to be recurrences of their psychiatric disorders. In all cases, they needed to be re-examined by the corresponding medical specialty and required diagnostic tests, in two cases hospital admission was needed. Emergency physicians and emergency psychiatrists often disagree on how to medically clear patients (Alam et al. Psychiatr. Clin. North Am. 2017;40(3):425–33; Janiak et al. JEM. 2012;43(5):866–70), some authors have even proposed protocols for doing this in a more systematic way (Shah et al. JEM. 2012;43(5):871–5). To avoid a delay in diagnosis and treatment and the consequences that may result from it, establishing guidelines for proper triage of patients with psychiatric history should be considered.Disclosure of InterestNone Declared

Unraveling the challenges of diagnosing dementia with Lewy bodies in a patient with alcohol and benzodiazepine misuse: A case study-based review

Dementia with Lewy bodies (DLBs) is the second most common cause of neurodegenerative dementia in the United States, after Alzheimer&amp;rsquo;s disease, and is often misdiagnosed. A history of substance use disorder (SUD) complicates the diagnosis process, and side effects of substance misuse can mirror or mask signs of degenerative dementia. The fluctuating cognition and mobility which would normally point toward DLB are erroneously seen as signs of SUD or polypharmacy. However, a history of SUD should not preclude the diagnosis of DLB or other forms of proteinopathy, as substance misuse can contribute to the development of neurodegenerative dementias. Both alcohol and benzodiazepines have a sedative effect as ligands to gamma-aminobutyric acid (GABA) receptors. Long-term use, misuse, and withdrawals can upset the delicate GABAergic/glutamatergic balance, resulting in adverse neuroimmune and neuroinflammatory responses which contribute to the pathologies seen in degenerative dementias, such as DLB. In this paper, we review the challenges, including limitations of standardized instruments for dementia and the harms of delayed diagnosis, in DLB diagnosis, in combination with our experiences drawn from studying a polypharmacy-practicing 68-year-old man with a 40-year history of benzodiazepine and alcohol use. Understanding the underlying mechanisms of SUD serves to destigmatize the condition to expedite treatment and further our knowledge of the relationship between neuroinflammation and dementia.
