Cigarette smoking among those with mental disorders in the US population: 2012-2013 update.

BACKGROUND: Recent nationally representative estimates from the USA suggest the prevalence of cigarette smoking continues to be much higher among those with mental disorders compared with those without; however, prevalence estimates for current cigarette use by specific diagnoses are outdated. METHODS: We analysed data from the National Epidemiologic Survey on Alcohol and Related Conditions III (2012-2013). We estimated the prevalence of lifetime and past-year smoking, lifetime and past-year daily smoking, and lifetime smoking cessation among ever smokers (ie, the quit ratio) among those with common mood, anxiety and substance use disorders in comparison to those without these disorders. RESULTS: Across disorders, smoking prevalence was higher and the quit ratio was lower among those with common mental disorders compared with those without, with twofold to sixfold relativedifferences in the odds of the magnitude. CONCLUSIONS: Despite tobacco control advances since 2000 and resulting declines in smoking prevalence, smoking remains extraordinarily more common among those with mood, anxiety and substance use disorders, with highest rates among those with bipolar and substance use disorders.

Placement of chronically homeless into different types of permanent supportive housing before and after a coordinated entry system: The influence of severe mental illness, substance use disorder, and dual diagnosis on housing configuration and intensity of services.

AIMS: Permanent supportive housing (PSH) is designed to house people who experience chronic homelessness with one or more of the following: serious mental illness (SMI), substance use disorders (SUD) or human immunodeficiency virus. The Department of Housing and Urban Development has required major metropolitan areas to develop a coordinated entry system (CES) to prioritize access to PSH to those who need it the most. The aim of this paper is to determine whether PSH residents with SMI, SUD, or dual diagnosis were more likely to be housed after implementation of CES and were more likely to be housed in housing models with more intensive services provided. METHODS: A cross-sectional survey with 855 residents of different PSH models. RESULTS: Those with SMI, SUD, or dual diagnosis were not more likely to be housed using the CES but were more likely to be housed in higher intensity service programs. CONCLUSIONS: Those with SMI are more likely to be housed in PSH with high-intensity services.

Comparison of opioid use disorder among male veterans and non-veterans: Disorder rates, socio-demographics, co-morbidities, and quality of life.

BACKGROUND AND OBJECTIVES: Amidst a surging national crisis of opioid use, concern has been expressed about its impact on veterans, but no study has presented a population-based comparison of opioid use disorder (OUD) among veterans and non-veterans. We analyzed national epidemiologic data to compare rates, correlates and impacts of the opioid crisis on male veterans and non-veterans. METHODS: Restricted data from 2012 to 2013 National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III) were used to compare veteran and non-veteran men on rates of OUD, as well as correlates of OUD including socio-demographic characteristics, psychiatric and substance use co-morbidities, and reductions in health-related quality of life (HRQOL). RESULTS: About 2.0% of veterans and 2.7% of non-veterans, estimated at 418,000 and 2.5 million men, respectively, met criteria for life-time OUD. In both groups, OUD was associated with younger age, lower income levels, and fewer years of education. OUD was associated minority race among veterans, but with non-Hispanic white race among non-veterans. Both veteran and non-veteran adults with OUD were at least five times more likely than their peers to have both psychiatric and substance use co-morbidities (p < .001) and they experienced strongly reduced HRQOL scores (Cohen's d = -.50 to -.93). DISCUSSION AND CONCLUSION: Veterans and non-veterans experience similar risk of OUD, similar correlates and adverse HRQOL impacts suggesting that similar treatment approaches may be effective for both groups. SCIENTIFIC SIGNIFICANCE: Our findings highlight comparable vulnerability of veterans to non-veterans in both the risk of OUD and adverse effects on HRQOL. (Am J Addict 2018;XX:1-9).

Long-Term Retention in an Outpatient Behavioral Health Clinic With Buprenorphine.

BACKGROUND AND OBJECTIVES: Despite high comorbidity between substance use disorders and other mental health diagnoses, there is a paucity of literature on buprenorphine treatment outcomes in outpatient mental health settings. This study aimed to identify rates and predictors of outpatient buprenorphine treatment retention in a Behavioral Health Clinic (BHC). METHODS: This retrospective cohort study of adults on buprenorphine used multiple logistic regression to identify clinical and demographic factors associated with 1- and 2-year treatment retention and buprenorphine adherence. RESULTS: Of 321 subjects, 169 (52.6%) were retained in treatment for at least 1 year; 114 (35.5%) were retained for 2 years or more. Buprenorphine adherence was 95.8% and 97.3% for 1- and 2-year retention groups, respectively. Predictors of 1-year retention included benzodiazepine co-prescription (adjusted odds ratio [AOR] = 2.4; 95% CI [1.30, 4.55]), having a diagnosis of other mood disorder (AOR = 3.4; [1.95, 5.98]), or nicotine use disorder (AOR = 2.4; [1.35, 4.27]). Predictors of 2-year retention included female gender (AOR = 2.1; [1.16, 3.73]), having a diagnosis of depressive disorder (AOR = 4.6; [1.49, 14.29]), other mood disorder (AOR = 3.6; [1.88, 6.88]), or nicotine use disorder (AOR = 2.0; [1.13, 3.52]). DISCUSSION AND CONCLUSION: During the study period, 52.7% and 35.5% of BHC patients treated with buprenorphine were retained for 1 and 2 years, respectively, comparable to the studies performed within primary care. Providing buprenorphine treatment within mental health clinics may serve patients who are already engaged with mental health providers but are reluctant to start new treatment within another treatment setting. SCIENTIFIC SIGNIFICANCE: Identifying common predictors of retention can help determine which patients require additional substance use treatment support. (Am J Addict 2019;28:339-346).

Prescription opioid misuse and comorbid substance use: Past 30-day prevalence, correlates and co-occurring behavioral indicators in the 2016 National Survey on Drug Use and Health.

BACKGROUND AND OBJECTIVES: Prescription opioid misuse has not been well examined in the context of comorbid substance use in representative samples of substance users. Past 30-day comorbid prescription opioid misuse and recreational substance use (eg, alcohol, marijuana, cocaine, etc.) was studied in a representative sample of substance users in the United States using the 2016 National Survey on Drug Use and Health (NSDUH). METHODS: Prevalence of prescription opioid misuse with and without comorbid substance use was estimated with the 2016 NSDUH. Generalized linear modeling was used to describe demographic correlates of opioid and comorbid substance use and explore the relation of opioid and comorbid substance use with social and behavioral health indicators. RESULTS: The majority of past month prescription opioid misusers reported use of other substances including cigarettes, alcohol, marijuana, or hard drugs (cocaine, methamphetamine, etc.). Males and younger respondents had a significantly higher risk of reporting past month prescription opioid misuse with illicit drug or polydrug use (p's < .01). Prescription opioid and polydrug users had the greatest odds of stealing property, selling drugs, having suicidal ideations, major depressive episode, and perceived treatment need in the past year compared to all other categories of prescription opioid misuse categories. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Prescription opioid misuse is likely a part of a larger set of psychological, behavioral, and mental health problems. More attention should be given to the profiles of recreational (non-medical) substance use involving prescription opioids to curtail the current opioid crisis and prevent other similar epidemics in the future.

A retrospective, population-based cohort study of driving under the influence, Alzheimer's disease diagnosis, and survival.

ABSTRACTIntroduction:The relationship between Alzheimer's Disease (AD) and alcohol addiction is poorly characterized. Arrests for driving under the influence (DUI) can serve as a proxy for alcohol addiction. Therefore, the potential association between DUI and AD could be helpful in understanding the relationship between alcohol abuse and AD. MATERIALS AND METHODS: A retrospective, population-based cohort study using state health and law enforcement data was performed. The study cross-referenced 141,281 South Carolina Alzheimer's Disease Registry cases with state law enforcement data. RESULTS: Of the 2,882 registry cases (1.4%) found to have a history of at least one DUI arrest, cases were predominantly White (58.7%) and male (77.4%). Results showed a correlation coefficient of 0.7 (p < 0.0001) between the age of first DUI arrest and the age of AD diagnosis. A dose-response relationship between the number of DUIs and age of AD onset was found to exist, where those with a history of DUI arrest were diagnosed an average of 9.1 years earlier, with a further 1.8 years earlier age at diagnosis in those with two or more arrests for DUI. A history of DUI arrest was also found to be negatively associated with survival after diagnosis, with a 10% decreased life expectancy in those with a DUI arrest history. CONCLUSIONS: Driving under the influence, a potential indicator of alcohol addiction, is associated with an earlier onset of AD registry diagnosis and shortened survival after diagnosis. This study contributes to the growing body of evidence suggesting that some cases of AD are alcohol related and, possibly, postponable or preventable.

Predictive Associations Among the Repeated Measurements of Anxiety, Depression, and Craving in a Dual Diagnosis Program.

Objective: Anxiety and depression commonly co-occur with substance use disorders. Conceptual models would presume that changes in anxiety and depression should lead to changes in drug and alcohol craving during treatment for co-occurring disorders, but no longitudinal investigation has explored this assumption. This study examined the associations among craving, anxiety, and depression in a dual diagnosis program. Methods: In all, 93 adult patients at a community-based dual diagnosis program for substance use disorders and comorbid anxiety and mood disorders provided daily ratings of anxiety and depression. We examined whether these ratings predicted changes in craving and vice versa. Results: Using hierarchical linear modeling to examine day-to-day change over time, we observed that anxiety and depression ratings uniquely and independently predicted subsequent craving ratings, and craving ratings also predicted subsequent anxiety and depression ratings. Conclusions: These preliminary findings support mutual maintenance models of substance use and psychiatric comorbidity, thus providing preliminary support for integrated programs that simultaneously address both problems. Implications and future directions are discussed.

Psychiatric Hospitalizations of Chronic Psychotic Disorder Patients With and Without Dual Diagnosis, Israel, 1963-2016.

Objective: A significant proportion of patients with severe mental illness also experience substance use disorder. For these dual diagnosis (DD) patients, treatment is more complicated and prognosis is worse. Despite the introduction of the Community Rehabilitation of Persons With Mental Health Disability Law in 2000 and ongoing national mental health reforms, psychiatric services in Israel are not meeting the needs of an increasing number of DD patients. This study examines, for the first time in Israel, the prevalence of DD and patterns of psychiatric hospitalizations of chronic psychotic disorder patients with and without substance use disorder. Methods: The National Psychiatric Case Registry provided data on 18,684 persons with schizophrenia/schizoaffective disorders, aged 18-65, with a psychiatric hospitalization during the period 1963-2016 (with at least one hospitalization in 2010-15). Patients were considered as having DD if their substance use disorder was indicated in at least two, or 20%, of hospitalizations. Regression modeling predicted hospitalization measures (number of hospitalizations, total days hospitalized, length of stay). Results were also analyzed by legal status of admission (voluntary or involuntary; psychiatrist-ordered and court-ordered). Results: One-third of patients with chronic psychotic disorder met DD criteria, with a threefold higher rate among males (37.1%) than females (12.8%). Particularly high rates of DD (nearly 50%) were noted among male immigrants from Ethiopia. Compared with non-substance use disorder patients, DD patients had a significantly younger mean age at first hospitalization and shorter average length of stay per hospitalization but a greater number of hospitalizations and total hospital days (p < .0001 for all comparisons). The associations between DD status and hospitalization characteristics remained significant even after accounting for the effects of confounding factors. Hospitalization characteristics were also associated significantly with sex, population group, age, age at first hospitalization, and country of origin. The rate of court-ordered observation or hospitalization was threefold higher in the DD group. Conclusions: These findings, which broadly align with other countries, reflect a scarcity of outpatient services for DD patients with schizophrenia/schizoaffective disorder and substance use disorder. To achieve long-term mental health improvements, an expansion of community-based integrative treatment and rehabilitation services is needed in Israel.

Profiles of Clinical Need Among Homeless Individuals with Dual Diagnoses.

This study explored patterns of clinical need among homeless individuals with dual diagnoses, and explored whether certain profiles are characteristic of different demographic groups. Data were drawn from two larger studies conducted with dually diagnosed, homeless individuals (n = 373). Hierarchical cluster analysis identified four subgroups: (1) Clinically least severe, characterized by less frequent psychological symptoms and no history of physical or sexual abuse; (2) Moderate clinical needs, including shorter history of substance use and less frequent psychological symptoms, but symptoms consistent with severe mental illness; (3) Clinically severe, with frequent anxiety, depression, past and recent physical or sexual abuse, and long history of substance use; (4) Least frequent psychological symptoms, but frequent history of physical or sexual abuse and long history of drug use. Women veterans were mostly likely to be classified in cluster 3, and male civilians in cluster 2. Subgroups of homeless individuals with dual diagnoses demonstrated different clusters of clinical needs, having implications for service delivery to the population.

Co-occurring mental illnesses and substance use disorders: Evidence from Cyprus.

Co-occurrence of substance misuse and mental health conditions is an important problem in the treatment of substance use disorders and mental illnesses. The focus of this paper is to investigate co-occurring disorders with feedback directly to patients on outpatient individual treatment adherence. The study is conducted using data from a randomly selected sample from an outpatient treatment centre of a private psychiatric clinic in Cyprus. Participants are individuals with substance (ab) use disorder and dependence, who had asked for admission and who had been advised to start individual treatment, after a standardized admission assessment with the European Addiction Severity Index (EuropASI). Despite the limitations of this study, the overall results do provide evidence of an association between mental illness and substance abuse. However, it is concluded that more research is needed in order to disentangle the dynamics of this dual relationship.

Gender differences in demographic and clinical characteristics of patients with opioid use disorder entering a comparative effectiveness medication trial.

BACKGROUND & OBJECTIVES: We investigated gender differences in individuals with opioid use disorder (OUD) receiving inpatient services and entering a randomized controlled trial comparing extended-release naltrexone to buprenorphine. METHODS: Participants (N = 570) provided demographic, substance use, and psychiatric information. RESULTS: Women were significantly younger, more likely to identify as bisexual, live with a sexual partner, be financially dependent, and less likely employed. Women reported significantly greater psychiatric comorbidity and risk behaviors, shorter duration but similar age of onset of opioid use. DISCUSSION/CONCLUSIONS: Findings underscore economic, psychiatric, and infection vulnerability among women with OUD. SCIENTIFIC SIGNIFICANCE: Interventions targeting these disparities should be explored, as women may face complicated treatment initiation, retention, and recovery. (Am J Addict 2018;27:465-470).

Differences in substance use, psychiatric disorders and social factors between Mexican adolescents and young adults.

BACKGROUND AND OBJECTIVES: Substance use disorders (SUDs) have high comorbidities with psychiatric disorders. Childhood and adolescence are particularly vulnerable developmental periods for the onset of SUDs. The objective of this study was to explore the differences, if any, between Mexican adolescents and young adults with respect to the prevalences of groups of psychiatric disorders, the types of substances used and the social factors involved. METHODS: This cross-sectional study included 781 patients evaluated at the Youth Integration Center in Mexico City. The diagnostic criteria for SUDs and psychiatric disorders were defined according to the DSM-IV and ICD-10. Associations between SUDs and psychiatric disorders were evaluated via multivariate analysis using logistic regression models. RESULTS: The adolescents were more frequently substance abusers, whereas the adults had legal problems more often than the adolescents. We showed that adolescents using inhalants or cocaine were 1.62 more likely to have attention deficit hyperactivity disorder (ADHD). Moreover, adults using inhalants were 3.33 times more likely to meet the criteria for a psychotic disorder. DISCUSSION AND CONCLUSIONS: We found that adolescents diagnosed with ADHD were more likely to have problems with use or abuse of or dependence on inhalants, and an elevated prevalence of parental SUDs was found in both the adolescent and adult groups. SCIENTIFIC SIGNIFICANCE: Our findings indicate that earlier diagnosis and intervention are necessary in adolescents with ADHD and/or parental SUDs to prevent more advanced psychiatric diseases and adverse social consequences during adulthood. (Am J Addict 2018;XX:1-7).

Sexual orientation disparities in the co-occurrence of substance use and psychological distress: a national population-based study (2008-2015).

PURPOSE: Although strong evidence documents the elevated prevalence of both substance use and mental health problems among sexual minorities (i.e., gay, lesbian, and bisexuals), relatively less research has examined whether risk of the co-occurrence of these factors is elevated among sexual minorities compared to heterosexuals. The object of this study was to (1) explore sexual orientation-based differences in substance use, psychological distress, and their co-occurrence in a representative sample in Sweden, and (2) examine if greater exposure to stressors, such as discrimination, victimization/threats, and social isolation, could explain these potential disparities and their co-occurrence. METHODS: Data come from the cross-sectional Swedish National Public Health Survey, which collected random samples of individuals (16-84 years of age) annually from 2008 to 2015, with an overall response rate of 49.7% (n = 79,568 individuals; 1673 self-identified as lesbian, gay, or bisexual). Population-level sexual orientation differences in substance use (i.e., alcohol, tobacco, and cannabis) and psychological distress were examined. RESULTS: Our findings showed significantly elevated prevalence of high-risk alcohol use, cannabis use, and daily tobacco smoking, among sexual minorities compared to heterosexuals. These substantial disparities in substance use more often co-occurred with psychological distress among sexual minorities than among heterosexuals. The elevated risk of co-occurring psychological distress and substance use was most notable among gay men relative to heterosexual men (adjusted odds ratio [AOR] = 2.65, CI 1.98, 3.55), and bisexual women relative to heterosexual women (AOR = 3.01, CI 2.43, 3.72). Multiple mediation analyses showed that experiences of discrimination, victimization, and social isolation partially explained the sexual orientation disparity in these co-occurring problems. CONCLUSIONS: This study adds to a growing body of research showing that sexual minorities experience multiple threats to optimal health and points toward future interventions that address the shared sources of these overlapping health threats in stigma-related stress.

Psychiatric and Substance Use Comorbidity in Treatment-Seeking Injection Opioid Users Referred From Syringe Exchange.

OBJECTIVE: The present study evaluated rates of co-occurring current psychiatric and substance use disorders in a sample of opioid-dependent treatment-seeking injection drug users referred from syringe exchange. METHODS: Participants (N = 208) completed the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (DSM) IV-R to assess current (within the past year) psychiatric and substance use disorders and the two most commonly diagnosed personality disorders (antisocial and borderline personality disorders). RESULTS: Forty-eight percent of the sample had a current Axis I psychiatric disorder, and 67% had a co-occurring current substance use disorder. Posttraumatic stress disorder (21%), major depression (17%), and bipolar I (12%) were the most prevalent Axis I psychiatric disorders, and cocaine use disorder (53%) was the most commonly co-occurring substance use disorder. Women were more likely to have diagnoses of most anxiety disorders and less likely to have diagnoses of alcohol use disorder or antisocial personality disorder. The presence of a personality disorder was associated with higher rates of cocaine and sedative use disorder. CONCLUSIONS: Findings suggest the importance of evaluating and treating co-occurring psychiatric and substance use disorders in the treatment of injection drug users with opioid dependence.

The Relationship Between Residential Mobility and Behavioral Health Service Use in a National Sample of Adults With Mental Health and/or Substance Abuse Problems.

OBJECTIVE: Individuals with mental health and/or substance abuse problems experience disparities in health care utilization. While previous studies have focused on individual and social determinants of health care use in these populations, few have investigated the role of residential stability, especially in relation to different types of service use (i.e., inpatient vs. outpatient treatment). The present study examined the relationship between residential mobility, defined as the number of residential relocations in the past year, and past-year use of four types of behavioral services (i.e., inpatient and outpatient mental health services, inpatient and outpatient substance abuse services) among a national sample of adults with mental health and/or substance abuse problems. METHODS: Data were drawn from the 2011-2014 National Survey of Drug Use and Health (unweighted N = 43,411). Based on prior literature and theory, we hypothesized that individuals who frequently relocate are more likely to use inpatient services and are less likely to use outpatient services. Logistic regression analyses were conducted and all models controlled for predisposing, need, and enabling factors. RESULTS: Compared to individuals who did not move in the past year, those who moved three or more times were more likely to report using inpatient mental health and substance abuse services. The relationship between residential mobility and outpatient mental health and substance use service use is not significant. CONCLUSIONS: The findings highlight the importance of understanding housing stability as a predictor factor of service use and access. Future research is needed to shed light on the pathway through which residential mobility affects behavioral health service utilization.

Gambling involvement among Native Americans, Blacks, and Whites in the United States.

BACKGROUND AND OBJECTIVES: This paper examines risk factors of gambling and problem gambling among racial subgroups in the U.S. population, namely Native Americans and blacks, for whom research data are lacking. METHODS: Findings are based on a large representative general population survey (n = 3,474) of gambling in the U.S. with an oversample of Native Americans (n = 549). Multiple domains were assessed including sociodemographic factors; ecological factors (census-defined neighborhood disadvantage, geocoded density of casinos within 30 miles of respondents' homes, and perceived gambling convenience); impulsivity; and alcohol abuse. RESULTS: After controlling for all variables in the study, neighborhood disadvantage has a significantly greater effect on overall gambling, frequent gambling, and problem gambling for Native Americans than for the rest of the U.S. POPULATION: In addition, the relationship between frequent gambling and heavier drinking is much stronger for blacks than for the rest of the U.S. DISCUSSION AND CONCLUSIONS: There is a lack of research on gambling involvement among minority groups in the U.S. Blacks and Native Americans are at a higher risk for problem gambling as compared with the rest of the population. Furthermore, social factors and alcohol abuse may show a stronger co-occurrence with gambling involvement among minority groups than among whites. SCIENTIFIC SIGNIFICANCE: This study is a large representative U.S. sample with sizeable numbers of Native Americans and blacks. Thus, prevalence rates and risk factors can be assessed for these important population subgroups. This will allow for targeted intervention programs for Native Americans and blacks with problem gambling and alcohol abuse. (Am J Addict 2017;26:713-721).

Nonmedical versus medical marijuana use among three age groups of adults: Associations with mental and physical health status.

BACKGROUND AND OBJECTIVE: Given that 29 U.S. states now have laws allowing medical marijuana use, this study examined mental and physical health correlates of medical versus nonmedical marijuana use among three age groups of adults (18-29, 30-49, and 50+). METHODS: Data came from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (N = 36,309 respondents aged 18+). Logistic regression models were used to examine age group differences in associations of substance use and mental disorders and health conditions with medical versus nonmedical marijuana use. RESULTS: Of all respondents, 9.74% (N = 3,784) reported past-year marijuana use. Of all past-year marijuana users, 11.03% (n = 445) reported medical use. Medical marijuana use rates were higher among the 50-64 age group (17.95%) than younger adults, and 32.88% of medical users, compared to 25.25% of nonmedical users, had past-year marijuana use disorder. The odds of medical marijuana use were higher among those with marijuana use disorder (OR = 1.87, 95% CI = 1.40-2.50) and personality disorder (OR = 1.42, 95% CI = 1.03-1.94), with no age group differences. However, older adults with alcohol use disorder and sleep problems and middle-age adults with arthritis had diminished odds of having used medical marijuana relative to young adults. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Given the high rates of marijuana use disorder among medical users, physicians should exercise caution in recommending marijuana for medical purposes, especially for younger adults. More research is needed on medical marijuana's safety and efficacy for patients at risk of marijuana use disorder. (Am J Addict 2017;26:697-706).

Posttraumatic Stress Symptoms and Alcohol-Related Outcomes Among Municipal Firefighters.

This study examined levels of posttraumatic stress symptoms (PTSS) and relationships between PTSS and alcohol-related outcomes in a near census of municipal firefighters. The study also assessed substance-use coping and drinking to cope as potential mediators of such outcomes. Firefighters (N = 740) completed measures that assessed PTSS, alcohol risk behaviors, alcohol problems, drinking motives, and coping with stress. Results showed that 32.4% of firefighters reported significant levels of PTSS using National Center for PTSD (2014) screening cutoff scores. Correlational analysis showed that PTSS was related to at-risk drinking (r = .18) and alcohol-related problems (r = .33), as well as use of maladaptive coping strategies (r = .58) and substance use coping (r = .40). Structural analyses comparing multiple alternative models suggested that a model that included substance use coping and drinking to cope as mediators of the association between PTSS and problem drinking provided the best fit to the data. Tests of multigroup invariance confirmed this model. Overall, PTSS were common in this population and they predicted maladaptive coping patterns and alcohol-related consequences. One implication of these findings is that fire departments might consider adding or enhancing screening and treatment options for PTS, alcohol misuse, or both.

Mental disorders and the use of primary health care services among homeless shelter users in the Helsinki metropolitan area, Finland.

BACKGROUND: Homelessness is associated with increased morbidity, mortality and health care use. The aim of this study was to examine the role of mental disorders in relation to the use of 1) daytime primary health care services and 2) after hours primary health care emergency room (PHER) services among homeless shelter users in the Helsinki Metropolitan Area, Finland. METHODS: The study cohort consists of all 158 homeless persons using the four shelters operating in the study area during two selected nights. The health records were analyzed over a period of 3 years prior to the sample nights and data on morbidity and primary health care visits were gathered. We used negative binomial regression to estimate the association between mental disorders and daytime visits to primary health care and after hours visits to PHERs. RESULTS: During the 3 years the 158 homeless persons in the cohort made 1410 visits to a physician in primary health care. The cohort exhibited high rates of mental disorders, including substance use disorders (SUDs); i.e. 141 persons (89%) had a mental disorder. We found dual diagnosis, defined as SUD concurring with other mental disorder, to be strongly associated with daytime primary health care utilization (IRR 11.0, 95% CI 5.9-20.6) when compared with those without any mental disorder diagnosis. The association was somewhat weaker for those with only SUDs (IRR 4.9, 95% CI 2.5-9.9) or with only other mental disorders (IRR 5.0, 95% CI 2.4-10.8). When focusing upon the after hours visits to PHERs we observed that both dual diagnosis (IRR 14.1, 95% CI 6.3-31.2) and SUDs (11.5, 95% CI 5.7-23.3) were strongly associated with utilization of PHERs compared to those without any mental disorder. In spite of a high numbers of visits, we found undertreatment of chronic conditions such as hypertension and diabetes. CONCLUSIONS: Dual diagnosis is particularly strongly associated with primary health care daytime visits among homeless persons staying in shelters, while after hours visits to primary health care level emergency rooms are strongly associated with both dual diagnosis and SUDs. Active treatment for SUDs could reduce the amount of emergency visits made by homeless shelter users.

Predicting Change in an Integrated Dual Diagnosis Substance Abuse Intensive Outpatient Program.

Research on routine outcome monitoring in psychotherapy settings is plentiful but not without implementation obstacles. In fact, there is a relative dearth of real-time outcome monitoring in substance use treatment settings. Numerous barriers to the development and implementation of clinical decision support tools and outcome monitoring of substance use patients, including the need to establish expected trajectories of change and use of reliable change indices have been identified (Goodman, McKay, & DePhilippis, 2013 ). The current study was undertaken to develop expected trajectories of change and to demonstrate the treatment effectiveness of a dual diagnosis intensive outpatient program. The expected trajectories of change for days of substance use and depression scores were developed using predictive equation models from derivation samples and then applied to cross-validation samples. Predictive equations to monitor substance use were developed and validated for all patients and for only patients who were actively using substance at the time of admission, as well as to monitor severity of their depression symptom on a weekly basis. Validation of the equations was assessed through the use of Cohen's kappa (κ), receiver operating characteristic curves, reliable change index, and percentage improvement. Large effect sizes for reductions in substance use (Cohen's d = .76) and depressive symptoms (d = 1.10) are reported. The best predictive models we developed had absolute accuracy rates ranging from 95 to 100%. The findings from this study indicate that predictive equations for depressive symptoms and days of substance use can be derived and validated on dual diagnosis samples.
