Examining the impact of substance use on hospital length of stay in schizophrenia spectrum disorder: a retrospective analysis. BMC Med 2024; 22:233. [PMID: 38853281 PMCID: PMC11163832 DOI: 10.1186/s12916-024-03447-3] [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: 09/01/2023] [Accepted: 05/28/2024] [Indexed: 06/11/2024] Open
Abstract
BACKGROUND Among patients diagnosed with schizophrenia, the presence of substance use poses an aggravating comorbidity, exerting a negative impact on the course of the disease, adherence to therapeutic regimens, treatment outcomes, duration of hospital stays, and the frequency of hospitalizations. The primary objective of the present study is to investigate the relationship between comorbid substance use disorders, antipsychotic treatment, and the length of stay in individuals hospitalized for treatment of schizophrenia. METHODS We conducted a retrospective analysis of electronic health records spanning a 12-month period, specifically focusing on adult patients diagnosed with schizophrenia who were discharged from the University Hospital of Psychiatry Zurich between January and December 2019. We documented the number and types of diagnosed substance use disorder, the antipsychotic treatment, the length of stay, and the number of previous hospitalizations for each patient. RESULTS Over a third (n = 328; 37.1%) of patients with schizophrenia had comorbid substance use with cannabis being the most frequent consumed substance. Patients with substance use (either single or multiple) were more frequently hospitalized; those with multiple substance use more frequently than those with a single substance use (F(2, 882) = 69.06; p < 0.001). There were no differences regarding the rate of compulsory admission. Patients with no substance use had a lower HoNOS score at discharge (F(2, 882) = 4.06). Patients with multiple substance use had a shorter length of stay (F(2, 882) = 9.22; p < 0.001), even after adjusting for duration of illness, previous hospitalizations, diagnosis, and antipsychotic treatment. CONCLUSIONS In patients with schizophrenia, comorbid single or multiple substance use has a relevant negative impact on treatment and thus on the course of disease. Substance use in patients with schizophrenia should therefore receive special attention in order to reduce re-hospitalization rates and improve the clinical outcome.

Substance use and self-poisoning in schizophrenia: 11-year findings from a national clinical survey of suicide in mental health patients in the UK. Schizophr Res 2024; 267:254-260. [PMID: 38581828 DOI: 10.1016/j.schres.2024.03.048] [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: 06/13/2023] [Revised: 10/03/2023] [Accepted: 03/28/2024] [Indexed: 04/08/2024]
Abstract
Suicide is the leading cause of unnatural death among people with schizophrenia. Substance use is a highly prevalent comorbid feature of schizophrenia and a modifiable risk factor for suicide. However, no studies have examined changes in the frequency of substance use or self-poisoning in those who died by suicide over time. Knowing this could support more tailored approaches to reducing specific risk factors and access to means in those with schizophrenia who are at risk of suicide. We conducted an 11-year observational study on a clinical survey of people with schizophrenia in the UK who died by suicide within 12 months of contact with mental health services between 2010 and 2020 (n = 2718). Overall, alcohol, cannabis and stimulants were the most frequently reported substances. The odds of lifetime use significantly increased over time for cannabis, stimulants, heroin, and benzodiazepines. There were differences in socio-demographic, behavioural and clinical factors between those with recent and historical alcohol and drug use before death. Deaths by hanging, jumping and self-poisoning were the most common suicide methods. Though deaths by hanging significantly increased over time, deaths by self-poisoning significantly decreased, especially by means of psychotropic medication and opioids. To improve risk management, clinical efforts should focus on identifying and treating people with schizophrenia using specific substances. Nationwide initiatives for improving safety in prescribing could be contributing to reduced risks of suicide via self-poisoning in this group.

Prevalence and clinical correlates of substance use disorders in South African Xhosa patients with schizophrenia. Soc Psychiatry Psychiatr Epidemiol 2021; 56:695-706. [PMID: 32797244 PMCID: PMC9630460 DOI: 10.1007/s00127-020-01942-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Accepted: 08/07/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE To determine the prevalence of substance use disorders (SUDs) in patients with schizophrenia in a sample from South Africa and compare the clinical and demographic correlates in those with and without co-occurring SUDs. METHODS Patients with schizophrenia were interviewed using the Xhosa version SCID-I for DSM-IV. We used logistic regression to determine the predictors of SUDs. RESULTS In the total sample of 1420 participants, SUDs occurred in 47.8%, with the most prevalent SUD being cannabis use disorders (39.6%), followed by alcohol (20.5%), methaqualone (6.2%), methamphetamine (4.8%) and other SUDs (cocaine, ecstasy, opioids, 0.6%). Polydrug use occurred in 40%, abuse occurred in 13.5%, and 39.6% had at least one substance dependence diagnosis. Significant predictors of any SUD were younger age (41-55 vs. 21-30: OR = 0.7, 95% CI = 0.5-0.9), male sex (OR = 8.6, 95% CI = 5.1-14.6), inpatient status (OR = 1.7, 95% CI = 1.3-2.1), post-traumatic stress symptoms (OR = 4.6, 95% CI = 1.6-13.3), legal (OR = 3.4, 95% CI = 2.0-5.5) and economic problems (OR = 1.4, 95% CI = 1.0-2.0). Methamphetamine use disorders occurred significantly less often in the Eastern compared to the Western Cape provinces. Inpatient status and higher levels of prior admissions were significantly associated with cannabis and methamphetamine use disorders. Post-traumatic stress symptoms were significantly associated with alcohol use disorders. Anxiety disorders were associated with other SUDs. CONCLUSION SUDs occurred in almost half of the sample. It is important for clinicians to identify the presence of SUDs as their presence is associated with characteristics, such as male sex, younger age, inpatient status, more prior hospitalisations, legal and economic problems, PTSD symptoms and anxiety.

Abstract
Background Cannabis is the second most used recreational drug in the United States and one of the most used substances in patients with schizophrenia spectrum disorder (SSD). Unfortunately, the increased use is likely to continue as more states legalize recreational use of cannabis. Although the association between cannabis and schizophrenia has been studied extensively, the understanding of the relationship is still evolving. In this study, we sought to determine the prevalence and potential factors associated with cannabis use (CU) among inpatients with SSD at a community teaching hospital. Methods We performed a retrospective review of the electronic medical charts of patients discharged from the psychiatric unit of our hospital from July 1, 2017 through October 31, 2017. Patients were included in this study if: 1) They were ≥ 18 years old; 2) They had discharge diagnosis of SSD; and 3) They had urine drug testing performed. Pertinent sociodemographic and clinical variables, including substance use status and hospital length of stay (LOS), were abstracted. Univariate frequencies and summary statistics were performed. Odds ratios (ORs) were determined by logistic regression analysis of bivariate and multivariate analyses. Results Three hundred sixty-five (52.2%) patients had a discharge diagnosis of SSD, and only 322 had urine toxicology result for cannabinoids and were included in analysis. Of the 322 patients, 41.5% (n = 133) screened positive for cannabinoids. Of the 133 patients, 78% were African American, 15% were Hispanic and 5% were White; 77% were male and the median age was 36 years. Bivariate analyses showed tobacco use (OR: 2.8, 95% confidence interval (CI): 1.7 - 4.6), alcohol use (OR: 3.4, 95% CI: 2.9 - 7.0), younger age (OR: 2.8, 95% CI: 1.8 - 4.5), male gender (OR: 2.9, 95% CI: 2.2 - 3.2), unemployment (OR: 3.91, 95% CI: 3.49 - 7.35), homelessness (OR: 3.18, 95% CI: 2.76 - 3.84) and LOS (OR: 3.46, 95% CI: 2.93 - 4.31) were significantly associated with CU. Result of multivariate analysis was similar to that found in bivariate analysis. Conclusions CU appears to be prevalent among patients with SSD. Clinicians and public health professionals are encouraged to understand the health implications of its use in patients with mental illness especially against the backdrop of current marijuana laws.

HIV, schizophrenia, and all-cause mortality: A population-based cohort study of individuals accessing universal medical care from 1998 to 2012 in British Columbia, Canada. Schizophr Res 2019; 209:198-205. [PMID: 31255392 DOI: 10.1016/j.schres.2019.04.020] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2018] [Revised: 02/01/2019] [Accepted: 04/26/2019] [Indexed: 11/20/2022]
Abstract
Schizophrenia is a severe mental illness with important implications for morbidity and mortality. This population-based cohort study examined the impact of schizophrenia diagnoses on all-cause mortality among a sample of people living with HIV (PLHIV) and a 10% random sample of individuals living without HIV (HIV-) in British Columbia (BC), through a data linkage between the BC Centre for Excellence in HIV/AIDS and Population Data BC's data holdings. Schizophrenia diagnoses were identified via International Classification of Diseases version 9 and version 10 codes. Age- and sex-adjusted all-cause mortality rates from January 1st, 1998 to December 31st, 2012 were calculated. Multivariable logistic models assessed (1) HIV status and mortality among individuals diagnosed with schizophrenia, (2) schizophrenia diagnosis and mortality among PLHIV, and (3) correlates of mortality among PLHIV concurrently diagnosed with schizophrenia (HIV+/SZO+). From 1998 to 2012, 6.3% of those with HIV had a schizophrenia diagnosis, compared to 1.1% of those without HIV. While significant declines in mortality rates were observed throughout the study period, mortality rates were highest among HIV+/SZO+. After adjustment for substance use disorder and age at baseline, HIV+/SZO+ had a 2.64 times greater odds of mortality (95% confidence interval [CI] = 2.14-3.25) compared to HIV-/SZO+. For PLHIV, a schizophrenia diagnosis was not associated with mortality after controlling for potential confounders (adjusted odds ratio [aOR] = 0.90, 95%CI = 0.74-1.09). Among HIV+/SZO+, age, history of injection drug use, ever having an AIDS-defining illness, and never being on anti-psychotic medication or accessing psychiatric services were associated with mortality. Efforts should be made to identify and link to care individuals disproportionately affected by schizophrenia and excess mortality, including those living with HIV.

Abstract
Background: Societal capacity to address the service needs of persons with concurrent mental health and substance-use disorders has historically been challenging given a traditionally siloed approach to mental health and substance-use care. As different approaches to care for persons with concurrent disorders emerge, a limited understanding of current models prevails. The goal of this paper is to explore these challenges along with promising models of coordinated care across Canadian provinces. Materials and methods: A scoping review of policies, service coordination and access issues was undertaken involving a review of the formal and gray literature from 2000 to 2018. The scoping review was triangulated by an analysis of provincial auditor general reports. Results: Models of concurrent disorders service were found to have evolved unevenly. Challenges related to the implementation of models of collaborative care and local networks that foster service coordination and policy accountability were found to inhibit integrated care. Conclusion: Emergent models of coordinated care were found to include collaborative care, regional networks with centralized access to care, clinical information-sharing, cross-training, improved scope of care to include psychologists and alignment of physician incentives with patient needs to better support patient care.

Abstract
BACKGROUND Comorbidity is highly prevalent between substance use disorders (SUDs) and schizophrenia. This systematic review and meta-analysis estimated prevalence rates of SUDs in epidemiological and treatment-seeking patients diagnosed with schizophrenia or first episode psychosis. METHODS A literature search of Medline, EMBASE, PsycINFO and CINAHL databases was conducted from 1990 to 2017 inclusive. Prevalence of co-morbid SUDs and schizophrenia were extracted and odds ratios (ORs) were calculated using random effects meta-analysis. Combining like studies was dictated how authors reported substance use. RESULTS There were 123 included articles with a total sample size of 165,811 subjects that yielded six epidemiological studies, 11 national or state case-registry studies, 20 large cohort studies and 86 clinical studies using in- or out-patient samples. The prevalence of any SUD was 41.7%, followed by illicit drugs (27.5%), cannabis (26.2%), alcohol (24.3%) and stimulant use (7.3%). Meta-analysis showed the pooled variance of any SUD in males was 48% which was significantly higher than that for females with schizophrenia (22.1%, OR 3.43, 95% CI 3.01, 3.92). Patients with SUD had an earlier age of onset of schizophrenia. Meta-regression showed prevalence increased over time for illicit drugs but not for other substances, including alcohol. CONCLUSIONS The meta-analysis revealed that SUDs in schizophrenia is highly prevalent and rates have not changed over time. This indicates SUD are difficult to treat in this patient population and there is an urgent need for more informative studies to help develop better prevention, detection and treatment of SUDs in persons with schizophrenia and co-morbid disorders.

Abstract
Objective: The impact of substance abuse on violent behavior in patients suffering from schizophrenia is well-known. However, the association between the pattern of substance abuse and certain aspects of criminal behavior like the severity of offense, the previous history of violence and the age at onset of the criminal career is still unclear. Method: To assess the relationship between substance abuse, schizophrenia and violent behavior we examined healthy non-offenders; healthy offenders; non-offenders suffering from schizophrenia; and offenders suffering from schizophrenia, with respect to different patterns of substance abuse (none, alcohol only, illicit drugs only, and multiple substances). Results: Healthy offenders as well as offenders and non-offenders suffering from schizophrenia are characterized by increased rates of alcohol and illicit drug abuse. Especially multiple substance abuse appears to lower the threshold of aggression and illegal behavior. This effect is more pronounced in subjects suffering from schizophrenia. In both offender groups the abuse of psychoactive substances is associated with an earlier onset of the criminal career, but has no impact on the severity of the offenses. Conclusion: Our results point to the need for a differentiated view on the contribution of substance abuse to the criminality of subjects suffering from schizophrenia.

Abstract
OBJECTIVE To investigate differences in physician-diagnosed psychiatric disorders between women who gave birth to children with a fetal alcohol spectrum disorder (FASD) diagnosis (study group) compared to women who gave birth to children without FASD (comparison group). METHODS We linked population-level health and social services data to clinical data on FASD diagnoses to identify study group ( n = 702) and comparison group ( n = 2097) women matched 1:3 on date of birth of index child, region of residence, and socioeconomic status. Regression modeling produced relative rates (RRs) for outcomes. RESULTS Mothers who gave birth to children with FASD had higher adjusted rates of substance use disorder (RR, 12.65; 95% confidence interval [CI], 8.99-17.80), personality disorder (RR, 12.93; 95% CI, 4.88-34.22), and mood and anxiety disorders (RR, 1.75; 95% CI, 1.49-2.07) before the pregnancy of the child. These mothers also had higher adjusted rates of maternal psychological distress during pregnancy (RR, 5.35; 95% CI, 4.58-6.35) and higher rates of postpartum psychological distress (RR, 1.71; 95% CI, 1.53-1.90). These women also had higher adjusted rates for antidepressant prescriptions before, during, and after the pregnancy. CONCLUSIONS A significant psychiatric burden exists for women giving birth to children with FASD. Clinicians should recognise the high rates of psychiatric concerns facing mothers who give birth to children with FASD and should offer treatment and support to these women to improve their health and well-being and prevent further alcohol-exposed pregnancies.

Abstract
This study sought to develop a typology of individuals with substance dependence (ISD) based on a longitudinal survey (n = 2,434) and 121 ISD. The latter were divided into three groups: newly abstinent individuals, chronic dependents and acute dependents. Individuals' typology was developed by cluster analysis. Newly abstinent individuals had fewer emotional problems and mental disorders in the previous 12 months. Four classes of ISD were identified, labelled respectively "chronic multi-substance consumption and mental disorders comorbidities," "multi-substance consumption," "alcohol and marijuana consumption" and "alcohol consumption only." Strategies adapted to each of these profiles could be promoted for more effective treatment.

Abstract
Social behavior is a complex integrative function that entails many aspects of the brain’s sensory, cognitive, emotional and movement capacities. Its neural processes are seldom simultaneous but occur according to precise spatiotemporal choreographies, manifested by the coordination of their oscillations within and between brains. Methods with good temporal resolution can help to identify so-called “neuromarkers” of social function and aid in disentangling the dynamical architecture of social brains. In our ongoing research, we have used dual-electroencephalography (EEG) to study neuromarker dynamics during synchronic interactions in which pairs of subjects coordinate behavior spontaneously and intentionally (social coordination) and during diachronic transactions that require subjects to perceive or behave in turn (action observation, delayed imitation). In this paper, after outlining our dynamical approach to the neurophysiological basis of social behavior, we examine commonalities and differences in the neuromarkers that are recruited for both kinds of tasks. We find the neuromarker landscape to be task-specific: synchronic paradigms of social coordination reveal medial mu, alpha and the phi complex as contributing neuromarkers. Diachronic tasks recruit alpha as well, in addition to lateral mu rhythms and the newly discovered nu and kappa rhythms whose functional significance is still unclear. Social coordination, observation, and delayed imitation share commonality of context: in each of our experiments, subjects exchanged information through visual perception and moved in similar ways. Nonetheless, there was little overlap between their neuromarkers, a result that hints strongly of task-specific neural mechanisms for social behavior. The only neuromarker that transcended both synchronic and diachronic social behaviors was the ubiquitous alpha rhythm, which appears to be a key signature of visually-mediated social behaviors. The present paper is both an entry point and a challenge: much work remains to determine the nature and scope of recruitment of other neuromarkers, and to create theoretical models of their within- and between-brain dynamics during social interaction.

Abstract
This study sought to identify profiles associated with substance dependence only, mental disorders only and co-occurring disorder respectively, using a broad range of socio-demographic, socio-economic, health beliefs, clinical and health services utilization variables concurrently. Based on a broad analytic framework, 423 participants diagnosed with substance dependence only, mental disorders only or co-occurring disorders within a 12-months period were studied. The study used comparison analysis, and a multinomial logistic regression model. Participants with dependence only and mental disorders only were in contrast in terms of gender, age, marital status, self-perception of physical health, perception of the physical conditions of their neighbourhood, impulsiveness, psychological distress and visit with a family physician in previous 12-months, while those with co-occurring disorders were in an intermediary position between the other two groups. Public authorities should especially promote strategies that could increase the capacity of family physicians to take care of individuals with substance dependence only.

Abstract
The dopamine D3 receptor (D3R) is a target for developing medications to treat substance use disorders. D3R-selective compounds with high affinity and varying efficacies have been discovered, providing critical research tools for cell-based studies that have been translated to in vivo models of drug abuse. D3R antagonists and partial agonists have shown especially promising results in rodent models of relapse-like behavior, including stress-, drug-, and cue-induced reinstatement of drug seeking. However, to date, translation to human studies has been limited. Herein, we present an overview and illustrate some of the pitfalls and challenges of developing novel D3R-selective compounds toward clinical utility, especially for treatment of cocaine abuse. Future research and development of D3R-selective antagonists and partial agonists for substance abuse remains critically important but will also require further evaluation and development of translational animal models to determine the best time in the addiction cycle to target D3Rs for optimal therapeutic efficacy.

Abstract
OBJECTIVE Stimulant abuse and dependence often complicate the care of people with psychotic disorders. This study systematically reviews the prevalence estimates reported for stimulant abuse and dependence in people with psychotic disorders, and examines personal, clinical, regional and methodological factors which explain variation in these rates. METHODS PsychINFO, EMBASE and MEDLINE (1946-2013) were searched systematically for studies reporting on stimulant drug use disorders in representative samples of people with psychotic disorders. Random effects models estimated the pooled rate of a stimulant use disorder, defined to include stimulant abuse and stimulant dependence. Study characteristics associated with heterogeneity in rates of stimulant use disorder were examined by subgroup analyses for categorical variables, by meta-regression for continuous independent variables and by multiple meta-regression. RESULTS Sixty-four studies provided 68 estimates of lifetime or recent stimulant use disorders in 22,500 people with psychosis. The pooled rate of stimulant use disorder was 8.9% (95% CI 7.4%, 10.5%). Higher rates of stimulant use disorders were reported in studies of affective psychosis, studies from inpatient settings, studies from the USA and Australia, and studies with higher rates of cannabis disorder; in multiple meta-regression analysis these factors explained 68% of between-study variance. Rates of stimulant use disorder were stable over time, and unrelated to age, sex, stage of psychosis, type of stimulant drug or study methodology factors. CONCLUSIONS Reported rates of stimulant use disorder in people with psychosis are much higher than in the general population but vary widely and are associated with regional, service setting and clinical differences between studies. It is likely that stimulants contribute to the overall burden of psychosis, and that social and environmental factors combine with drug and illness-related factors to influence stimulant use in psychosis.

Abstract
BACKGROUND Schizophrenia is among the major causes of disability worldwide and the mortality from cardiovascular disease (CVD) is significantly elevated. There is a growing concern that this health challenge is not fully understood and efficiently addressed. METHODS Non-systematic review using searches in PubMed on relevant topics as well as selection of references based on the authors' experience from clinical work and research in the field. RESULTS In most countries, the standardized mortality rate in schizophrenia is about 2.5, leading to a reduction in life expectancy between 15 and 20 years. A major contributor of the increased mortality is due to CVD, with CVD mortality ranging from 40 to 50% in most studies. Important causal factors are related to lifestyle, including poor diet, lack of physical activity, smoking, and substance abuse. Recent findings suggest that there are overlapping pathophysiology and genetics between schizophrenia and CVD-risk factors, further increasing the liability to CVD in schizophrenia. Many pharmacological agents used for treating psychotic disorders have side effects augmenting CVD risk. Although several CVD-risk factors can be effectively prevented and treated, the provision of somatic health services to people with schizophrenia seems inadequate. Further, there is a sparseness of studies investigating the effects of lifestyle interventions in schizophrenia, and there is little knowledge about effective programs targeting physical health in this population. DISCUSSION The risk for CVD and CVD-related deaths in people with schizophrenia is increased, but the underlying mechanisms are not fully known. Coordinated interventions in different health care settings could probably reduce the risk. There is an urgent need to develop and implement effective programs to increase life expectancy in schizophrenia, and we argue that mental health workers should be more involved in this important task.

Abstract
This paper examines the barriers to employment faced by job seekers (JS) with mental illness and additional substance-use issues. Semi-structured interviews concerning barriers to employment for JS with mental illness and substance-use problems and strategies to improve employment outcomes were conducted with stakeholders associated with an employment service provider specialising in mental illness (n = 17). Stakeholders were JS, family members who provide significant support to JS [support persons (SP)] and staff [employment staff (ES)]. Data were collected between May and August 2009 at the premises of the employment service provider in metropolitan Sydney. Thematic analysis of transcribed interview data was conducted to develop a meaningful data framework. The expectations of JS and SP regarding employment outcomes were higher than those of ES. Length of time unemployed was perceived as the most important barrier to future employment associated with mental illness, and substance-use problems were associated with lower, more variable motivation, restrictions on the environments where JS could work and more negative community and employer perceptions. The findings are consistent with studies from non-vocational settings and provide direction for meeting the needs of clients with mental illness and additional substance-use problems. Ensuring alignment between JS and ES concerning service goals and expected timeframes may improve JS motivation, satisfaction with service delivery and ultimately, employment outcomes.

Abstract
The aim of this study was to further explore the properties of axis IV in the Diagnostic and statistical manual of mental disorders, 4th edition (DSM-IV). In a naturalistic cross-sectional design, a group (n = 163) of young (18-25 years old) Swedish psychiatric outpatients was assessed according to DSM-IV. Psychosocial and environmental problems/axis IV were evaluated through structured interviewing by a social worker and by self-assessment on a questionnaire. Reliability between professional assessment and self-assessment of axis IV was examined. Concurrent validity of axis IV was also examined. Reliability between professional and self-assessed axis IV was fair to almost perfect, 0.31-0.83, according to prevalence and bias-adjusted kappa. Categories of psychosocial stress and environmental problems were related to the presence of axis I disorders, co-morbidity, personality disorders and decreasing Global Assessment of Functioning (GAF) values. The revised axis IV according to DSM-IV seems to have concurrent validity, but is still hampered by limited reliability.

Abstract
The aim of this study was to compare three groups of Brazilian psychoactive substance (PAS) abuse patients (crack cocaine users, cocaine snorters, and non-cocaine PAS users) in terms of psychiatric comorbidities and severity of psychosocial problems. A cross-sectional, multi-center study was conducted at five Brazilian research centers. A total of 738 current PAS abusers seeking specialized treatment (outpatient and inpatient clinics) were assessed using the sixth version of the Addiction Severity Index (ASI-6): 293 patients using crack cocaine were compared with 126 using powder cocaine and 319 using non-cocaine PAS (mostly alcohol and marijuana). Psychiatric comorbidities were assessed in a smaller sample (290 cases), originating from three of the centers, using the Mini International Neuropsychiatric Interview Plus (MINI-Plus). Crack and powder cocaine users were significantly younger than non-cocaine PAS users (31.1 ± 8.1 and 32.9 ± 8.8 vs. 42.4 ± 12, respectively; p < .001). Crack users presented a higher rate of antisocial personality disorder (25%) than powder cocaine (9%) and non-cocaine PAS users (9%), even when adjusted for confounding factors (Pr = 2.6; 95% CI 1.10-6.40). According to ASI-6 summary scores, crack users presented a significantly higher rate of occupational, family, and legal problems and reported more illegal and violent activities such as burglary and theft (23%) and threatening or assaulting (32%) than non-cocaine PAS users. Our findings, combined with the recent increase observed in the prevalence of crack use in Brazil, highlight the severity of psychiatric symptoms and psychosocial problems related to this powerful drug and corroborate the already suggested association between crack/cocaine, violence, and legal problems. Treatment programs for crack users should routinely consider the possibility of associated psychiatric comorbidities, such as antisocial personality disorder, which may affect treatment outcomes.

Abstract
Among 1,610 patients with psychotic or mood disorders in routine psychiatric practice, odds ratios (crude and adjusted for age, education, gender, and race) quantified associations between the presence of comorbid cannabis abuse/dependence and seven psychosocial problems. Results revealed a higher prevalence of five of seven Axis IV psychosocial problems among patients who had a psychotic or mood disorder and a comorbid cannabis use disorder. The results underscore the need for careful screening and treatment of comorbid cannabis abuse/dependence among patients with psychotic or mood disorders given the prominent associated psychosocial impairments in this population.

Abstract
During recent decades, interest in the prevention of mental illnesses has increased. Improved diagnostic tools, the advent of atypical antipsychotic medications and the development of phase-specific psychosocial treatments have made intervention research in people at ultra-high risk for developing schizophrenia or a related psychotic disorder possible. Preliminary data suggest that low doses of atypical antipsychotic medications augmented by psychosocial treatments may delay the onset of psychosis in some individuals. Findings support further research for the establishment of best-practice standards.

Abstract
OBJECTIVE Our aim was to review recent studies and estimate the rate of cannabis use disorders (CUDs) in schizophrenia, as well as to examine the factors affecting this rate. METHODS We conducted an electronic search of 3 literature databases and a manual search of articles from 1996 to 2008. The key words used were "schizophreni*," "psychos*s," "psychotic," "cannabis abuse," "cannabis dependence," "cannabis use disorder," "substance use disorder," "substance abuse," "substance dependence," and "dual diagnosis." Articles that reported diagnoses according to the Diagnostic and Statistical Manual of Mental Disorders or International Classification of Diseases were included. Regression analysis was used to examine how estimated rates of CUDs are affected by various study characteristics such as the classification system, inpatient vs outpatient status, study location, proportion of males, age of the sample, or duration of illness. RESULTS Thirty-five studies met our search criteria. The median current rate of CUDs was 16.0% (interquartile range [IQR] = 8.6-28.6, 10 studies), and the median lifetime rate was 27.1% (IQR = 12.2-38.5, 28 studies). The median rate of CUDs was markedly higher in first-episode vs long-term patients (current 28.6%/22.0%, lifetime 44.4%/12.2%, respectively) and in studies where more than two-thirds of the participants were males than in the other studies (33.8%/13.2%). CUDs were also more common in younger samples than in the others (current 38.5%/16.0%, lifetime 45.0%/17.9%). CONCLUSIONS Approximately every fourth schizophrenia patient in our sample of studies had a diagnosis of CUDs. CUDs were especially common in younger and first-episode patient samples as well as in samples with a high proportion of males.

Abstract
OBJECTIVE To describe the attitudes of patients and their mental health providers regarding participation in a controlled trial of directly monitored naltrexone (NTX) treatment for alcohol dependence in schizophrenia. METHOD Ninety participants with schizophrenia and their providers were asked to report opinions of treatment with oral NTX or placebo 3 times per week for 12 weeks, motivational counseling (MI), and voucher-based incentives (VBI) for attendance. RESULTS Seventy-nine percent of participants "liked the study a lot," and 94% reported that it was helpful. Study components rated as helpful by participants were: VBI (95% of participants), meeting with staff 3 times per week (84%), reporting alcohol use (82%), MI (82%), reporting psychiatric symptoms (73%), breath alcohol testing (72%), and study medication (57%). Benefits reported by patients were: feeling better mentally (67%), drinking less (52%), feeling better physically (49%), and stopping drinking (27%). Seventy percent of providers reported that the study was helpful. Benefits noted by providers included: reduced drinking (33%), better treatment adherence (32%), stopping drinking (23%), and reduced psychiatric symptoms (22%). Patient/provider responses agreed on helpfulness with stopping or reducing drinking. CONCLUSIONS Most participants with schizophrenia liked participating in a clinical trial of directly observed naltrexone treatment for alcohol dependence, and found incentives for attendance, frequent staff contact and monitoring of drinking, and motivational counseling to be the most helpful. Most participants reported improvement in mental health and reduced drinking. Mental health providers also reported that the study was helpful, but they did not describe the same degree of benefit as did patients.

Abstract
The study's purpose was to determine treatment outcomes for patients who present with drug use vs. those presenting with no drug use at admission to a psychiatric day treatment program. Consecutively admitted patients completed confidential interviews which included psychological distress and quality of life measures and provided urine specimens for toxicology at admission and six month follow-up. Subjects positive by past 30 day self-report or urinalysis were categorized as drug users. Major psychiatric diagnoses were: major depression 25%; bipolar, 13%; other mood 13%; schizoaffective 13%; schizophrenia 13%. Drug use at admission was: cocaine 35%; marijuana 33%; opiates 18%, (meth)amphetamines, 6% For each of these drugs, the percentage of patients positive at admission who remitted from using the drug significantly exceeded the percentage negative at baseline who initiated using the drug. Overall, there were significant decreases in psychological distress and significant improvement on quality of life, but no change on positive affect. There were no significant differences between drug users and non-drug users on symptom reduction and improvement in quality of life. Psychiatric day treatment appears to benefit comorbid patients by reducing the net number of patients who actively use certain common drugs and by improving psychological status and quality of life to the same degree as for non-drug using patients.

Abstract
Mental illness (MI) and illicit drug use (DU) frequently co-occur. We sought to determine the individual and combined effects of MI and DU on highly active antiretroviral therapy (HAART) receipt and HIV-RNA suppression among individuals engaged in HIV care. Using 2004 data from the HIV Research Network (HIVRN), we performed a cross-sectional study of HIV-infected patients followed at seven primary care sites. Outcomes of interest were HAART receipt and virological suppression, defined as an HIV-RNA <400 copies/ml. Independent variables of interest were: (1) MI/DU; (2) DU only; (3) MI only; and (4) Neither. We used chi-squared analysis for comparison of categorical variables, and logistic regression to adjust for age, race, sex, frequency of outpatient visits, years in clinical care, CD4 nadir, and study site. During 2004, 10,284 individuals in the HIVRN were either on HAART or HAART eligible defined as a CD4 cell count < or =350. Nearly half had neither MI nor DU (41%), 22% MI only, 15% DU only, and 22% both MI and DU. In multivariate analysis, co-occurring MI/DU was associated with the lowest odds of HAART receipt (Adjusted Odds Ratio: 0.63 (95% CI: (0.55-0.72]), followed by those with DU only (0.75(0.63-0.87)), compared to those with neither. Among those on HAART, concurrent MI/DU (0.66 (0.58-0.75)), DU only (0.77 (0.67-0.88)), were also associated with a decreased odds of HIV-RNA suppression compared to those with neither. MI only was not associated with a statistically significant decrease in HAART receipt (0.93(0.81-1.07)) or viral suppression (0.93 (0.82-1.05)) compared to those with neither. Post-estimation testing revealed a significant difference between those with MI/DU and DU only, and MI/DU and MI only. Co-occurring MI and DU is associated with lower HAART receipt and viral suppression compared to individuals with either MI or DU or neither. Integrating HIV, substance abuse, and mental healthcare may improve outcomes in this population.

Factors associated with substance use problem among Maryland Medicaid enrollees affected by serious mental illness. Addict Behav 2009; 34:757-63. [PMID: 19487082 DOI: 10.1016/j.addbeh.2009.05.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2008] [Revised: 05/04/2009] [Accepted: 05/11/2009] [Indexed: 11/21/2022]
Abstract
The objective of this study was to identify long-term factors associated with substance use problem among individuals affected by severe mental illness. Prospective data come from the 1994, 1998, and 2000 waves of the Maryland Mental Health Outcomes Survey conducted among a sub-cohort of adult Medicaid recipients affected by serious mental illness. We estimated factors associated with alcohol and drug problem, as well as a hierarchy of substance use problem severity constructed from the alcohol and drug problem outcomes. Drug problem was the strongest factor associated with alcohol problem, and vice versa. Conceptualizing alcohol and drug problem separately, and as a hierarchy of severity, revealed distinct profiles of significant factors. Further research is warranted to explore the utility of modeling substance use problem in terms of a hierarchy of severity.

Abstract
OBJECTIVE Our aim was to present recent studies of alcohol use disorders (AUDs) in patients with schizophrenia, estimate overall prevalence and characteristics affecting the prevalence of AUDs. METHOD We conducted a search using three literature databases and a manual search on articles published in 1996-2008. Meta-regression was used to study how prevalence is affected by different study characteristics. Articles that reported diagnoses according to DSM or ICD diagnostic systems were included. RESULTS Altogether 60 studies met our criteria. The median of current AUD prevalence was 9.4% (inter-quartile range, IQR 4.6-19.0, 18 studies) and median of lifetime AUD prevalence 20.6% (IQR 12.0-34.5, 47 studies). In studies using DSM-III-R median prevalence was higher than that in studies using DSM-IV, ICD-9 or ICD-10 (32/17/11/6%). CONCLUSION Approximately every fifth patient with schizophrenia had lifetime AUD diagnosis. When contrasted with the most recent review, there might be a descending trend in AUD prevalence in patients with schizophrenia.

Abstract
Nearly half of the people suffering from schizophrenia also present with a lifetime history of substance use disorders (SUD), a rate that is much higher than the one seen among unaffected individuals. This phenomenon suggests that the factors influencing SUD risk in schizophrenia may be more numerous and/or complex than those modulating SUD risk in the general population. It is critically important to address this comorbidity because SUD in schizophrenic patients is associated with poorer clinical outcomes and contributes significantly to their morbidity and mortality.

Abstract
This study examined whether concurrent medical status contributes to employment outcomes among those with psychiatric disabilities. Thirty-five percent (n = 70) of the 200 participants reported being currently employed. Sixty-three percent (n = 127) reported one or more co-occurring medical conditions; thirty-six percent (n = 71) reported two or more, and twenty-one percent (n = 41) reported three or more co-occurring medical conditions. Individuals with higher self-ratings of physical health functioning were more likely to be employed. Neither the number of co-occurring medical conditions nor any specific medical condition was related to employment status. Recommendations to enhance existing models of supported employment programs with physical health and wellness promotion components are offered.

Abstract
The combination of new medications and effective psychosocial rehabilitation interventions has the potential to improve outcomes for individuals with schizophrenia significantly. Patients who have persistent positive symptoms can benefit from cognitive behavior therapy. Impairments in social competence can be addressed with social skills training. Supported employment programs may increase the ability of patients who have schizophrenia to obtain competitive employment. Family psychoeducational approaches, treatments for comorbid substance abuse, and cognitive rehabilitation approaches that enhance or bypass impairments in cognitive functioning are discussed. This article describes current efforts to incorporate these evidence-based principles of rehabilitative medicine into the management of schizophrenia.

Abstract
Most studies of unemployment among chronic drug users (CDUs) are drug-user treatment-based and there is little information on employment/unemployment among CDUs not in treatment. Between June 2003 and September 2004, 492 CDUs in Miami-Dade, Florida, were administered a quantitative survey at baseline and 6 months later; employment status was measured. Descriptive statistics showed that only 15% were employed at both periods, an equal percentage becoming employed and unemployed at 6 months. The majority of CDUs were unemployed at both time periods. Men were more likely than women to exhibit consistent employment over the two time periods. The study's limitations are noted and future research is suggested.

Abstract
BACKGROUND A reduction in suicide among individuals with mental illness is an international public-health priority. Approximately 10% of patients with schizophrenia will die by suicide. OBJECTIVE The goal of this study was to describe social and clinical characteristics of people with schizophrenia who completed suicide, including aspects of the clinical care they received. METHOD A national clinical survey was conducted based on a 4-year (1996-2000) sample of people in England and Wales who had died by suicide and had been in contact with mental health services in the previous 12 months. RESULTS Of 20,927 individuals who committed suicide, 5,099 (24%) were known to have been in contact with mental health services in the year prior to death. Completed questionnaires were returned on 4,859 cases of suicide. Of these, 960 (20%) were diagnosed with schizophrenia. These suicides were characterized by more violent modes of death, with over a quarter (27%) jumping from a height or in front of a moving vehicle compared to 10% of the remaining sample. They were more likely than the other individuals in the sample to be young, male, unmarried, and from an ethnic minority with high rates of unemployment. Rates of previous violence and drug abuse were high and they were proportionally more likely to be inpatients at the time of death and to have been noncompliant with medication. Patients with schizophrenia and comorbid substance abuse showed particularly complex social and clinical morbidity. CONCLUSIONS Measures that may prevent suicide among patients with schizophrenia include improved ward safety, closer supervision in both inpatient and community settings, particularly for those with poor medication compliance, and effective treatment of substance abuse.
