[PMID: 38039919 DOI: 10.1016/j.comppsych.2023.152439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 11/01/2023] [Accepted: 11/16/2023] [Indexed: 12/03/2023] Open
Abstract
BACKGROUND It is a common aim to reduce psychiatric readmissions. Although risk factors for readmissions were described, specific data in the group of patients with potentially aversively experienced involuntary admissions are lacking. To better understand underlying mechanisms, it is important to identify factors that are linked to readmissions in this specific patient group, which is the purpose of the current paper. METHODS A four-year cohort of N = 3575 involuntary admissions (IA) was followed-up for subsequent re-hospitalization. Demographic, administrative and clinical factors associated with short- (within 30 days) or long-term (> 30 days) readmissions were examined using logistic regression modelling. RESULTS Almost half of all IA cases were readmitted within the observation period, whereof every fifth readmission was within the first month after discharge from the involuntary index hospitalization. Adjusted regression modelling revealed problematic substance use at admission and assisted living or homelessness as risk factors for readmission, while high functioning at discharge, anxiety disorders, no subsequent treatment after discharge or IA due to danger to others were negatively associated with readmission. Factors specifically linked to short-term readmission were substance use and personality disorders, abscondence or discharge by initiation of the clinic, as well as being discharged to any place except the patient's home. There were no specific risk-factors for long-term readmission. CONCLUSIONS To prevent readmissions after IA, especially for patients at risk, the aim of treatment strategies should be to focus on intensive discharge planning, enable continuous treatment in the outpatient setting, and provide social support.

Abstract
Sports medicine physicians and athletic trainers regularly encounter athletes who misuse substances that put them at risk for adverse health, social, interpersonal, academic, psychological, and performance effects. The three most encountered substances are alcohol (binge drinking), cannabis (marijuana), and tobacco/nicotine vaping. Early detection using self-report screening instruments, adverse consequences questionnaires, and urine testing are reviewed. Brief interventions that involve personalized feedback, goal setting, support system involvement, psychoeducation, contingency management, and/or motivational interviewing are highlighted. Lack of response to brief intervention or progression to a substance use disorder should prompt the consideration of referral to a substance specialty level of care.

Abstract
Little is known about the prevalence of Conduct Disorder (CD) and symptoms of CD in high risk psychosis persons at both clinical and community populations in LMICs and in particular Kenya. This study aimed to document (1) the prevalence of CD diagnosis and symptoms in youth who screened positive for psychosis and (2) the associated mental disorders and substance use in the same cohort in LMIC. The sample size was 536 students who had screened positive on the Washington Early Recognition Center Affectivity and Psychosis (WERCAP) from a population of 9,742 high school, college and university students, but had not converted to a psychotic disorder. We collected data on socio-demographic characteristics and used the following tools: Economic indicators tool; the Diagnostic Interview Schedule (DIS) tool for DSM-5 diagnosis; World Health Organization (WHO) Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST). Basic descriptive statistics, chi-square test, Fisher's exact test, Pearson correlation and Poisson regression were conducted. Five percent (5%) of the respondents met the criteria for DSM-5 CD. Indeterminate CD comprised 10.1%. Male gender, all substances except hallucinogens lifetime, obsessive compulsive disorder, psychosis, agoraphobia, social phobia, drug abuse/dependence, antisocial personality disorder, oppositional defiant disorder, suicidality, WERCAP screen for bipolar disorder and WERCAP screen for schizophrenia were significantly (p < 0.05) associated with CD. Deceitfulness or theft criteria symptoms showed that CD had no significant gender difference. Criteria symptoms in aggression to people and animals, destruction of property and serious violations of rules were more common among males. Our findings suggest the need to screen for and diagnose CD, mental disorders and substance use in high risk psychosis youths in Kenya. This will inform integrated management.

Abstract
OBJECTIVES Perinatal substance use is a growing concern across the United States. Universal screening, brief intervention, and referral to treatment (SBIRT) is one systems-level approach to addressing perinatal substance use. The objective of this study is to assess early efforts to implement SBIRT in an outpatient obstetric clinic. METHODS The research team implemented universal screening with the 5 P's screening tool. Providers then engaged patients in a brief intervention and referred to a care manager who then worked with patients via tele-health to connect patients with needed services. Feasibility was measured through the collection of aggregate data describing frequency of universal screening and referral to treatment. The implementation team met bi-weekly to reflect on implementation barriers and facilitators. RESULTS In the first year of implementation, 48.5% of patients receiving care in the clinic completed the 5 P's screener at least once during the perinatal period. Screening occurred in a little over a quarter (26.5%) of eligible visits. Of the 463 patients that completed the 5 P's at least once during the perinatal period, 195 (42%) unique patients screened positive (answered yes to at least one question). CONCLUSIONS FOR PRACTICE Early implementation efforts suggest this approach is feasible in this obstetric setting. Similar implementation studies should consider implementing universal screening for substance use and perinatal mood and anxiety disorders simultaneously; guide efforts using an implementation framework; invest resources in more intensive training and ongoing coaching for providers; and adopt strategies to track frequency and fidelity of brief intervention.

Abstract
Substance abuse is a serious problem in our society. In particular, household or parental substance abuse could lead to adverse childhood experiences for the affected children. However, little is known about the prevalence of substance abuse among parents, especially in Asian societies. Moreover, although the trauma model of addiction has significant implications for the prevention and treatment of substance abuse, most evidence comes from Western samples. To address these knowledge gaps, we examined the prevalence of substance abuse in a sample of mothers in Taiwan and tested the trauma model of substance abuse. A total of 867 Taiwanese mothers completed standardized self-report assessments in 2023. The screening results indicated that the 12-month prevalence of drug abuse and alcohol abuse was 12.3% and 7.3%, respectively; 15.5% had either or both drug and alcohol abuse. Most types of trauma exposure were associated with drug abuse severity, while interpersonal stress and dissociative symptoms were associated with alcohol abuse severity, even after controlling for a variety of demographic and health variables as well as general psychopathology (i.e., depressive symptoms). The relatively high prevalence of substance abuse among Taiwanese mothers in our sample is concerning, particularly when compared to the rates reported in other Asian samples. We also provide preliminary cross-cultural evidence supporting the self-medication theory and the trauma model of substance abuse in the Asian context. We discuss the potential importance of addressing trauma and stress to prevent substance abuse and call for follow-up studies.

Abstract
AIMS Hepatitis C virus (HCV) infection among drug users presents an important public health problem; however, little recognition and few approaches to address this issue in Japan. This study was conducted to investigate the current disease status by assessing anti-HCV antibody (Ab) seroprevalence among people who inject drugs (PWIDs) and people who use drugs (PWUDs) in Hiroshima, Japan. METHODS This study was a psychiatric single-site chart review in patients with drug abuse problems in the Hiroshima region. The primary outcome was anti-HCV Ab prevalence among PWIDs who underwent anti-HCV Ab testing. The secondary outcomes included the prevalence of anti-HCV Ab among PWUDs who underwent anti-HCV Ab testing and the proportion of patients who underwent anti-HCV Ab examination. RESULTS A total of 222 PWUD patients were enrolled. Among these, 16 patients (7.2%) had records of injection drug use (PWIDs). Eleven (68.8%) of the 16 PWIDs received anti-HCV Ab tests, and 4 (36.4%, 4/11) were anti-HCV Ab-positive. Among 222 PWUDs, 126 (56.8%) patients received anti-HCV Ab tests, and 57 of these patients (45.2%, 57/126) were anti-HCV Ab-positive. CONCLUSION The prevalence of anti-HCV Ab among PWIDs and PWUDs who visited the study site was higher than the general population, which was 2.2% among hospitalized patients between May 2018 and November 2019. Considering the World Health Organization's (WHO) elimination goal and recent advances in HCV treatment, patients with drug abuse experience should be encouraged to take HCV tests and consult hepatologists for further investigations and treatment if they are positive for anti-HCV Ab.

Abstract
BACKGROUND Screening, brief intervention, and referral to treatment (SBIRT) is an evidence-based intervention for substance use. Health care professionals may not receive SBIRT training or know of substance use's intersection with sexual activity. This pilot survey inquired about SBIRT training history, attitudes, and comfort among outpatient health care professionals, including assessing sexual activity-related use. METHODS We conducted a snowball cross-sectional survey of outpatient health care professionals at a large southeastern academic medical center in June 2021 with 4-point Likert questions covering demographics, substance use attitudes, SBIRT training history, and comfort implementing SBIRT. Analysis used descriptive statistics and stratification by demographic and practice characteristics. RESULTS Seventy-three professionals responded, of whom 82% were White and 66% were female. Forty-seven percent were 30 to 39 years old, 33% were internal medicine professionals, and 59% reported previous SBIRT training. All participants reported believing substance use is a significant health issue. Most reported that they were comfortable or somewhat comfortable assessing patients for substance use (85%), dropping to 60% discussing sexual activity. Advanced practice providers and physicians identified more comfort with rapport building around substance use than other health care respondents. Professionals in infectious diseases and psychiatry reported the greatest comfort assessing substance use with concurrent sexual activity. CONCLUSIONS There are gaps in SBIRT training and beliefs among health care professionals. Although health care workers report that assessing substance use is important, some professionals endorsed more comfort discussing substance use with patients than others, especially when inquiring about sexual activity. Future work could replicate the pilot to inform increasing comfort through training in the intersection of substance use and sexuality.

Abstract
We analyzed the results of a nationwide questionnaire administered to 699 stimulant offenders and examined sex differences in the association between various psychosocial problems and treatment history for substance use disorder. Based on their attributes, we predominantly evaluated the treatment and support provided to women with substance use disorder. The rates of childhood (before the age of 18) traumatic experiences (physical, psychological, and sexual abuse and neglect) and lifetime intimate partner violence were significantly higher in women than in men. The history of treatment for substance use disorder was also significantly higher in women than in men, at 15.8% for men and 42.4% for women [χ2 (1) = 41.223, p < 0.001]. Logistic regression analysis was performed using the treatment history of substance use disorder as the dependent variable. The results showed that treatment history was significantly associated with the total drug abuse screening test-20 score and suicidal ideation in men and with survivors of child abuse and eating disorders in women. A comprehensive assessment is required for several issues, such as child abuse, domestic violence, trauma symptoms, eating disorders, and drug problems. Moreover, an integrated treatment for substance use disorder, trauma, and eating disorders is required for female stimulant offenders.

Abstract
Adolescent cannabis use is a modifiable health behavior with potential adverse developmental, cognitive, psychological, and health effects. Over the last 2 decades, work to promote implementation of screening, brief intervention, and referral to treatment has improved screening, use of validated screening tools, and preventive messaging. Current intervention strategies for cannabis use are associated with modest, short-term effects, and referral to treatment is limited by availability of resources for adolescent substance use. This article provides an update on the evidence base for screening, brief intervention, referral to treatment, and the current state of implementation focused on management of cannabis use disorder.

Abstract
INTRODUCTION The aim of the present study was to examine for the first time the factorial, construct, and predictive validity of the motivation for treatment (MfT) scale in a cohort of patients undergoing inpatient-qualified alcohol withdrawal treatment with the goal of referring patients to further treatment. The MfT scale has previously been evaluated in different settings of substance abuse treatment, revealing factorial ambiguity. To the best of our knowledge, the present study is the first study that conducted comprehensive factor analyses versus separate analyses of the factors conducted in prior studies in order to clarify the aforementioned factorial ambiguity. METHODS A total of 249 patients (mean age 45.2 years (SD = 10.3); 34.4% females) with alcohol dependence were assessed. Data were obtained from four inpatient clinics specialized in qualified alcohol withdrawal treatment in Germany. First, confirmatory factor analyses were carried out to examine the fit of the four models discussed in the literature. Second, an exploratory factor analysis was conducted. Correlations of the new factors with other motivational constructs and referral to a subsequent treatment were investigated as measures of construct and predictive validity. RESULTS None of the four models showed an acceptable fit to the data in confirmatory analyses. The exploratory analysis suggested to eliminate seven items because of inappropriate factor loadings and resulted in a shortened MfT scale, which consists of three factors based on 17 items. For the latent variables "problem recognition," "desire for help," and "treatment readiness," satisfactory composite reliability was found with 0.82, 0.80, and 0.78, respectively. Evidence for predictive validity was found in the correlation between "treatment readiness" and referral to a subsequent treatment. DISCUSSION/CONCLUSION The new shortened MfT scale exhibited remarkable parsimony, which is desirable in settings such as withdrawal treatment, where patients frequently are cognitively or physically impaired. Despite its briefness, construct and predictive validity were better than in the original version of the MfT scale. The factorial validity of the suggested scale needs to be corroborated in further research.

Abstract
BACKGROUND The TAPS Tool ("Tobacco, Alcohol, Prescription drug, and illicit Substance use") is a screening and brief assessment for detecting unhealthy substance use in healthcare settings that was developed by the National Institute on Drug Abuse Clinical Trials Network and validated in a multisite study. Our team developed a Spanish language version of the TAPS Tool that supports provider- and self-administration screening using a mobile/web-based platform, the TAPS Electronic Spanish Platform (TAPS-ESP). METHODS This article describes the protocol and rationale for a study to validate the TAPS-ESP in a sample of Spanish-speaking primary care patients recruited from a network of community-based clinics in Texas (target N = 1,000). The TAPS-ESP will be validated against established substance use disorder diagnostic measures, alternative screening tools, and substance use biomarkers. The study will subsequently examine barriers and facilitators to screening with the TAPS-ESP from a provider workflow perspective using qualitative interviews with providers. DISCUSSION Validating a Spanish language version of the TAPS Tool could expand access to evidence-based, linguistically accurate, and culturally relevant substance use screening and brief assessment for an underserved health disparity population. TRIAL REGISTRATION The study was registered with www. CLINICALTRIALS gov : NCT05476588, 07/22/2022.

Abstract
BACKGROUND Youth in sub-Saharan Africa are at high risk of substance use yet lack access to substance use interventions. The goal of this project was to evaluate the feasibility and acceptability of a peer-delivered, single-session substance use screening and brief intervention program for youth in Kenya. METHODS This was a convergent parallel mixed methods study utilizing both quantitative and qualitative approaches. Two trained peer providers administered the screening and brief intervention program to 100 youth aged 15-24 years. To evaluate the implementation of the intervention, we collected quantitative and qualitative data. Feasibility and acceptability were quantitatively assessed using the Dissemination and Implementation Measures. Fidelity was assessed by rating all 100 audio-recorded sessions using a checklist. To obtain qualitative feedback on the intervention, we conducted five focus group discussions with 25 youths and six semi-structured interviews with two peer providers and four clinic leaders. The semi-structured interviews were guided by the Consolidated Framework for Implementation Research. Quantitative data was analyzed via descriptive statistics using STATA. Qualitative data was analyzed using thematic analysis with NVIVO. RESULTS The lifetime prevalence of any substance use was 50%. The mean level of acceptability of the intervention from the perspective of the youth was 3.53 (SD 0.15), meaning that the youth found the intervention to be acceptable "a lot" of the time. Mean levels of implementation outcomes (acceptability, adoption, Acceptability, Appropriateness, Feasibility, Reach/access, Organizational climate, General leadership skills, and Sustainability) as rated by peer providers and clinic staff ranged between 2.61 ("a moderate amount") and 4.0 ("a lot"). In qualitative data, youth reported that the intervention was helpful and useful in enabling them to stop or reduce substance use. The peer providers felt that the intervention was easy to implement, while the clinic leaders felt that available resources were adequate, and that the intervention aligned well with the goals of the clinic. CONCLUSION Our findings suggest that the peer-delivered screening and brief intervention program was perceived as acceptable to the youth and feasible to implement.

Abstract
BACKGROUND Substance use disorders (SUD) pose a significant public health problem in Uganda. Studies indicate that integrating mental health services into Primary Health Care can play a crucial role in alleviating the impact of SUD. However, despite ongoing efforts to integrate these services in Uganda, there is a lack of evidence regarding the preparedness of health facilities to effectively screen and manage SUD. Therefore, this study aimed to assess the readiness of health facilities at all levels of the health system in Mbale, Uganda, to carry out screening, diagnosis, and management of SUD. METHODS A health facility-based cross-sectional study was carried out among all the 54 facilities in Mbale district. A composite variable adapted from the WHO Service Availability and Readiness Assessment manual (2015) with 14 tracer indicators were used to measure readiness. A cut-off threshold of having at least half the criteria fulfilled (higher than the cutoff of 7) was classified as having met the readiness criteria. Descriptive analyses were performed to describe readiness scores across various facility characteristics and a linear regression model was used to identify the predictors of readiness. RESULTS Among all health facilities assessed, only 35% met the readiness criteria for managing Substance Use Disorders (SUD). Out of the 54 facilities, 42 (77.8%) had guidelines in place for managing SUD, but less than half, 26 (48%), reported following these guidelines. Only 8 out of 54 (14.5%) facilities had staff who had received training in the diagnosis and management of SUD within the past two years. Diagnostic tests for SUD, specifically the Uri stick, were available in the majority of facilities, (46/54, 83.6%). A higher number of clinical officers working at the health centres was associated with higher readiness scores (score coefficient 4.0,95% CI 1.5-6.5). CONCLUSIONS In this setting, a low level of health facility readiness to provide screening, diagnosis, and management for substance use disorders was found. To improve health facility readiness for delivery of care for substance use disorders, a frequent inventory of human resources in terms of numbers, skills, and other resources are required in this resource-limited setting.

Abstract
INTRODUCTION Veteran populations are frequently diagnosed with mental health conditions such as substance use disorder and PTSD. These conditions are associated with adverse outcomes including a higher risk of suicide. The Veterans Health Administration (VHA) has designed a robust mental health system to address these concerns. Veterans can access mental health treatment in acute inpatient, residential, and outpatient settings. Residential programs play an important role in meeting the needs of veterans who need more structure and support. Residential specialty types in the VHA include general mental health, substance use disorder, PTSD, and homeless/work programs. These programs are affiliated with a DVA facility (i.e., medical center). Although residential care can improve outcomes, there is evidence that some patients are discharged from these settings before achieving the program endpoint. These unplanned discharges are referred to using language such as against medical advice, self-discharge, or irregular discharge. Concerningly, unplanned discharges are associated with patient harm including death by suicide. Although there is some initial evidence to locate factors that predict irregular discharge in VHA residential programs, no work has been done to examine features associated with irregular discharge in each residential specialty. METHODS We conducted a retrospective cohort study of patients who were discharged from VHA residential treatment programs between January 2018 and September 2022. We included the following covariates: Principal diagnosis, gender, age, race/ethnicity, number of physical health conditions, number of mental health diagnostic categories, marital status, risk of homelessness, urbanicity, and service connection. We considered two discharge types: Regular and irregular. We used logistic regression to determine the odds of irregular discharge using models stratified by bed specialty as well as combined odds ratios and 95% CIs across program specialties. The primary purposes are to identify factors that predict irregular discharge and to determine if the factors are consistent across bed specialties. In a secondary analysis, we calculated facility-level adjusted rates of irregular discharge, limiting to facilities with at least 50 discharges. We identified the amount of residual variation that exists between facilities after adjusting for patient factors. RESULTS A total of 279 residential programs (78,588 patients representing 124,632 discharges) were included in the analysis. Substance use disorder and homeless/work programs were the most common specialty types. Both in the overall and stratified analyses, the number of mental health diagnostic categories and younger age were predictors of irregular discharge. In the facility analysis, there was substantial variation in irregular discharge rates across residential specialties even after adjusting for all patient factors. For example, PTSD programs had a mean adjusted irregular discharge rate of 15.3% (SD: 7.4; range: 2.1-31.2; coefficient of variation: 48.4%). CONCLUSIONS Irregular discharge is a key concern in VHA residential care. Patient characteristics do not account for all of the observed variation in rates across residential specialty types. There is a need to develop specialty-specific measures of irregular discharge to learn about system-level factors that contribute to irregular discharge. These data can inform strategies to avoid harms associated with irregular discharge.

Obstet Gynecol 2023; 142:1169-1178. [PMID: 37769307 DOI: 10.1097/aog.0000000000005385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 07/06/2023] [Indexed: 09/30/2023]
Abstract
OBJECTIVE To measure racial inequities in drug testing among pregnant people during the first prenatal visit based on their drug use disclosure pattern. METHODS We used data from a cohort study of patient-clinician communication patterns regarding substance use in first prenatal visits from February 2011 to August 2014. We assessed racial differences (Black-White) in the receipt of urine toxicology testing, stratifying on patients' drug use disclosure to the clinician. RESULTS Among 341 study participants (205 Black [60.1%] and 136 White [39.9%] participants), 70 participants (33 Black [47.1%] and 37 White [52.9%] participants) disclosed drug use, and 271 participants (172 Black [63.5%] and 99 White [36.5%] participants) did not disclose drug use during their first obstetric visit. Of 70 participants who disclosed drug use, 50 (28 Black [56.0%] and 22 White [44.0%] White) had urine drug testing conducted. Black pregnant patients who disclosed drug use were more likely to be tested for drugs than their White counterparts in the adjusted regression analysis (adjusted odds ratio [aOR] 8.9, 95% CI 1.3-58.6). Among the 271 participants who did not disclose drug use, 38 (18 Black [47.4%] and 20 White [52.6%] participants) had urine drug testing conducted. For those who did not disclose drug use, the adjusted model showed no statistically significant differences in urine drug testing by patients' race (aOR 0.7, 95% CI 0.3-1.6). CONCLUSION When pregnant people disclosed drug use, clinicians were more likely to order urine drug testing for Black pregnant people compared with their White counterparts, suggesting clinician racial bias. Current practice patterns and protocols such as urine drug testing in pregnancy care deserve review to identify and mitigate areas of potential clinician discrimination.

[PMID: 37997088 DOI: 10.1016/s0140-6736(23)02146-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 08/25/2023] [Accepted: 09/22/2023] [Indexed: 11/25/2023]
Abstract
BACKGROUND Since 2015, the risks of dying due to drug-related causes are higher in prison than in the general population, with opiates and psychoactive substances being the most common substances recorded on death certificates in prison. Many individuals use drugs before entering the prison environment, it is not clear which individuals continue to use drugs while in prison. This study is a first step towards identifying characteristics of those who use drugs in prison, while exploring substances commonly used. METHODS This retrospective cross-sectional analysis was performed on 299 men (mean age 38 years [SD 11]) in a long-stay UK prison in South Wales who participated in a research study exploring cardiometabolic risk in prison, in which substance misuse was included as a risk variable. All men aged 25 years or older with no previous diagnosis of cardiometabolic illness were eligible to participate. Data were collected between Oct 7 and Oct 23, 2019. Participants were asked details about their substance use before and since entering the prison. Mental wellbeing was assessed using the short Warwick Edinburgh Mental Wellbeing Score and low mental wellbeing calculated as 1 SD below the population mean score. To examine associations between characteristics (age groups, mental wellbeing, exposure to prison environment) and drug use, we used binary logistic regression (adjusted for characteristics such as age group, mental wellbeing, and exposure to prison environment ). FINDINGS Overall, 195 (65%) of 299 participants reported a history of drug use before entering prison. Since entering prison 49 (16%) participants reported using drugs including methadone, and 24 (8%) reported using drugs excluding methadone. The next leading substances used in prison were spice (11 [4%] participants) and cannabis (six [2%] participants). All those who used drugs in prison had a history of drug use. Individuals more likely to continue using drugs in prison were aged 39 years and younger (adjusted odds ratio [aOR] 4·72, 95% CI 1·88-11·89; p=0·0009), with reported low mental wellbeing (3·38, 1·54-7·41; p=0·002), and had spent collectively more than 2·5 years in the prison environment (4·77, 2·09-10·91; p=0·0002). INTERPRETATION This study, from a limited sample, describes the characteristics of those who use drugs in prison. Harm reduction interventions targeted to these individuals could reduce the risk of prison drug-related deaths. These findings should be interpreted with some caution, as this is a single site and may not reflect the wider UK prison environment. FUNDING Public Health Wales.

A latent class analysis of mental disorders, substance use, and aggressive antisocial behavior among Swedish forensic psychiatric patients. Compr Psychiatry 2023; 127:152428. [PMID: 37778180 DOI: 10.1016/j.comppsych.2023.152428] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 09/23/2023] [Accepted: 09/25/2023] [Indexed: 10/03/2023] Open
Abstract
BACKGROUND Patients in the forensic mental health services (FMHS) with a mental disorder, a co-occurring substance use disorder (SUD), and high risk of aggressive antisocial behavior (AAB) are sometimes referred to as the 'triply troubled'. They suffer poor treatment outcomes, high rates of criminal recidivism, and increased risk of drug related mortality. To improve treatment for this heterogeneous patient group, more insight is needed concerning their co-occurring mental disorders, types of substances used, and the consequent risk of AAB. METHODS A three-step latent class analysis (LCA) was used to identify clinically relevant subgroups in a sample of patients (n = 98) from a high-security FMHS clinic in Sweden based on patterns in their history of mental disorders, SUD, types of substances used, and AAB. RESULTS A four-class model best fit our data: class 1 (42%) had a high probability of SUD, psychosis, and having used all substances; class 2 (26%) had a high probability of psychosis and cannabis use; class 3 (22%) had a high probability of autism and no substance use; and class 4 (10%) had a high probability of personality disorders and having used all substances. Both polysubstance classes (1 and 4) had a significantly more extensive history of AAB compared to classes 2 and 3. Class 3 and class 4 had extensive histories of self-directed aggression. CONCLUSIONS The present study helps disentangle the heterogeneity of the 'triply troubled' patient group in FMHS. The results provide an illustration of a more person-oriented perspective on patient comorbidity and types of substances used which could benefit clinical assessment, treatment planning, and risk-management among patients in forensic psychiatric care.

Abstract
INTRODUCTION Presentations related to illicit drugs are a feature of emergency department practice. Clinicians may form a belief that a patient is intoxicated with illicit drugs based on patient self-report, clinical features on presentation and the local prevalence of illicit drug use. But evidence of the accuracy of this assessment is lacking. The Western Australian Illicit Substance Evaluation (WISE) study enrolled patients believed by their treating clinician to be intoxicated with illicit drugs, and this analysis aims to evaluate the validity of this belief. METHODS A blood sample was taken on patient arrival and details of patient history, examination and interventions were collected by clinical and research staff. Toxicological examination of biological samples used liquid chromatography-mass spectrometry techniques including Quadrupole Time of Flight screening and Triple Quadrupole targeted analyses. RESULTS Of 632 study presentations, 518 had illicit drugs detected representing a positive predictive value of 0.82 (95% confidence interval 78.7, 84.9). Those with illicit drugs detected were significantly less likely to arrive by police transport (p = 0.010) or to have used alcohol (p < 0.001). They were significantly more likely to report illicit drug use (p < 0.001) and a much smaller proportion were admitted to a psychiatric ward (3.5% vs. 19.3%, p < 0.0001). Heart rate and systolic blood pressure were significantly higher in the illicit drug group (p = 0.004 and p = 0.003). DISCUSSION AND CONCLUSIONS In this study, the positive predictive value of clinicians determining if their patient had taken illicit drugs was 0.82. Contemporaneous biochemical analysis in the clinical setting would increase this accuracy and inform patient care.

Abstract
OBJECTIVE To develop an accessible index which quantifies MHSUD burden among patients of Veterans Affairs hospitals. METHOD We used 21 disorder categories provided by the diagnostic and statistical manual (DSM) to characterize diagnoses among primary care (PC) patients. For each patient, we generated counts of unique disorder categories present during the PC encounter or in the year prior. We used these counts to generate multiple indexes, which we compared in a 60% training sample of our population. Using model fit statistics generated from ordered multinomial logistic regressions, we identified the subset of DSM categories which, structured as index, were most predictive of MHSUD hospitalization and death. We validated and fine-tuned the form of the selected index in the full population using measures of calibration and discrimination. RESULTS In model development, the index (I-6) which best fit the data (R2 = 0.191) included the following six disorder categories: substance use, depressive, psychotic, bipolar, trauma, and personality. When applied in the full population and weighted by disorder severity, this index demonstrated good predictive discrimination for MHSUD death (C = 0.66) and hospitalization (C = 0.88) and was well calibrated in comparisons of observed versus predicted outcomes. CONCLUSIONS We recommend the I-6 as a parsimonious and effective tool for MHSUD burden risk adjustment.

Abstract
In recent years, mitragynine has been consistently detected in driving under the influence of drug (DUID) cases. In this paper, we evaluate 3 years (2017-2019) worth of DUID data from arrested drivers in Orange County, CA, USA. From the 25,398 DUID cases received in those 3 years, there were 60 (0.24%) cases with detectable concentrations, >10 ng/mL, of mitragynine. The majority of drivers were male (90%) and were stopped during the week (81%), considered Monday 0000 to Friday 1159. The concentration range for all mitragynine cases was 10.5-960 ng/mL, with a mean of 109 ng/mL and a median of 58 ng/mL. Forty four of the 60 cases were also screened for 7-hydroxymitragynine, and 27 (63%) were positive. The police reports and drug recognition expert evaluations were collected and evaluated. No case contained solely mitragynine, and the most common drugs detected in combination were central nervous system depressants (ethanol, followed by benzodiazepines), stimulants (methamphetamine and cocaine) and opioids (fentanyl and indication of heroin). Two cases containing only one other psychoactive substance are discussed more thoroughly to attempt to identify the contributions of mitragynine to driving impairment. Collected demographic, toxicological and field observations are presented for all cases.

Abstract
PURPOSE OF REVIEW Despite significant negative outcomes, the co-occurrence of personality disorders (PDs) and substance use disorders (SUDs) continues to be underrecognized, and the mechanisms contributing to this co-occurrence remain unclear. This review summarizes recent work on PD-SUD co-occurrence, with a focus on borderline and antisocial PDs, general substance use patterns among those with PDs, and the association of personality traits with SUDs. RECENT FINDINGS The prevalence of co-occurring PD-SUD is generally high, with estimates ranging depending on the type of PD and SUD, the population assessed, and the sampling methods and measures used. Current theoretical explanations for co-occurrence include shared etiology and predisposition models, with research highlighting the importance of transactional processes. Potential underlying mechanisms include personality traits and transdiagnostic characteristics. Recent research has increased focus on substances besides alcohol, dimensional models of personality pathology, and transactional explanations of co-occurrence, but more research is needed to disentangle the nuanced PD-SUD relationship.

Forensic Sci Int 2023; 352:111835. [PMID: 37748427 DOI: 10.1016/j.forsciint.2023.111835] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 09/11/2023] [Accepted: 09/18/2023] [Indexed: 09/27/2023]
Abstract
BACKGROUND Driving under the influence of drugs (DUID) is a risk factor for traffic accidents. The testing of oral fluid by roadside immunochromatography and laboratory-confirmed chromatography coupled to mass spectrometry (LC-MS/MS) analysis to detect drug abuse has increased in France. The aim of this study was to describe the trends observed in drivers testing positive for illicit drugs in oral fluid and to investigate the concordance between the two analytical methods used. METHODS We received for confirmation 3051 oral fluid samples from drivers who had tested positive at the roadside with a Drugwipe-5S® device between 2018 and 2021 around Grenoble, France. Samples were collected with FLOQSwab® and analyzed by LC-MS/MS (THC, amphetamine, methamphetamine, MDMA and MDA, MDEA, cocaine and benzoylecgonine, morphine and 6-monoacetylmorphine) at Grenoble Alpes University Hospital, France. Binomial logistic regression was performed to evaluate consumption trends. RESULTS Most of the drivers were men (93.2%), with a median age of 26 years (range: 14-66 years). Cannabis (94.6%) cocaine (17.5%) and MDMA (2.5%) were the drugs most frequently detected. Poly-drug use was observed in 17.3% of drivers and involved cannabis and cocaine in 85.3% of these drivers. Poly-drug use was more frequent among drivers over the age of 32 years (OR, 3.48; 95% CI, 2.59-4.68; p ≤ .001), as was cocaine use (OR, 5.15; 95% CI, 3.75-7.08; p ≤ .001). The frequency of positive tests for amphetamines was higher in women than in men (OR, 2.53; 95% CI, 1.50-4.27; p ≤ .001). The positive predictive value of Drugwipe-5S was 98.2% for cannabis, 22.6% for amphetamines, 75.4% for cocaine and 17.3% for opiates. At least one discrepancy between Drugwipe-5S® and LC-MS/MS results was observed for 22.3% of the samples tested. CONCLUSION We report recent trends for drivers testing positive for illicit drugs in oral fluid in France. Cannabis was the most prevalent drug of abuse identified, suggesting that a general prevention program might be useful. Our results also highlight the need for LC-MS/MS confirmation when screening oral fluid for drugs of abuse.

Abstract
OBJECTIVE The current model of obstetric care does not integrate multiple subspecialty services for high-risk pregnancies with substance use disorder (SUD), resulting in fragmented care. We describe the framework of our multidisciplinary and integrated perinatal substance use clinic and provide recent clinical outcomes. METHODS We detail the Partnering for the Future (PFF) clinic, which integrates numerous subspecialty and support services for patients with SUDs and complex mental health needs. Additionally, a retrospective chart review of patients receiving care in the PFF clinic from 2017 to 2021 was completed. RESULTS Seven integrated services are detailed with a focus on reducing stigma, providing trauma-informed care and mitigating harm. During the study period, 182 patients received care in PFF clinic, with opioid use disorder the most common indication for care. Co-occurring mental illness was common (81%). NICU admissions and severe NOWS diagnosis declined after the implementation of Eat-Sleep-Console. Social services identified care coordination, transportation assistance and adjustment counseling as the most common needs. A novel virtual behavioral health consultation service was successfully launched. CONCLUSIONS Our integrated care model supports the holistic care of pregnant people with SUD and mental health disease. Patient-centered care and co-located services have improved perinatal outcomes, particularly for opioid-exposed pregnancies.

Abstract
BACKGROUND The Health of the Nation Outcome Scale (HoNOS) is a widely used 12-item tool to assess mental health and social functioning. The French version has an added 13th item measuring adherence to psychotropic medication. The aim of the current study is to uncover the unknown pattern of the new item 13 and to compare the unidimensional and multidimensional fit of the new HoNOS-13 using Item Response Theory (IRT). This research question was studied among inpatients with substance use disorder (SUD). METHODS Six hundred and nine valid questionnaires of HoNOS-13 were analyzed using unidimensional (one-factor) and multidimensional (two-factor) IRT modeling. RESULTS The multidimensional model suggesting a first factor capturing psychiatric/impairment-related issues and a second factor reflecting social-related issues yielded better goodness-of-fit values compared to the unidimensional solution. This resulted in an improvement of all slope parameters which in turn translates to better discriminative power. Significant improvement in item location parameters were observed as well. The new item 13 had a good discriminative power (1.17) and covered a wide range of the latent trait (- 0.14 to 2.64). CONCLUSIONS We were able to validate the 13-item questionnaire including medication compliance and suggest that the HoNOS-13 can be recommended as a clinical evaluation tool to assess the problems and treatment needs for inpatients with SUD. Interestingly, the majority of item response categories are endorsed by respondents who are below and above the average levels of HoNOS. This indicates that the scale is able to discriminate between participants both at the low and at the high ends of the latent trait continuum. More importantly, the new item 13 has a good discriminative power and covers a broad range of the latent trait below and above the mean. It therefore has the desired profile of a good item and is a useful measure for the assessment of mental health and social functioning. Trial registration ClinicalTrials.gov, Identifier: NCT03551301.
