Co-Occurring Psychiatric and Substance Use Disorders: Clinical Survey Among a Rural Cohort of Italian Patients

Perceived Higher Unmet Care Needs among Adults in Permanent Supportive Housing

This study is original in that it assesses various types of care needs, barriers to care, and factors associated with higher unmet needs among 308 permanent supportive housing (PSH) residents in Quebec (Canada). Data from structured interviews that featured the Perceived Need for Care Questionnaire were collected from 2020 to 2022, controlling for the COVID-19 pandemic period. Eight types of care (e.g., information, counseling) were accounted for. Based on the Behavioral Model for Vulnerable Populations, predisposing, need, and enabling factors associated with higher unmet care needs were assessed using a negative binomial regression model. The study found that 56% of adult PSH residents, even those who had lived in PSH for 5 + years, had unmet care needs. Twice as many unmet needs were due to structural (e.g., care access) rather than motivational barriers. Living in single-site PSH, in healthier neighborhoods, having better quality of life and self-esteem, and being more satisfied with housing and outpatient care were associated with fewer unmet care needs. PSH residents with co-occurring mental disorders (MD) and substance use disorders (SUD), and with moderate or severe psychological distress were likely to have more unmet needs. Better access to care, counseling and integrated treatment for co-occurring MD-SUD might be improved, as well as access to information on user rights, health and available support. Welfare benefits could be increased, with more peer support and meaningful activities, especially in single-site PSH. The quality of the neighborhoods where PSH are located might also be better monitored.

Investigating the Effectiveness of Brexpiprazole in Subjects with Schizophrenia Spectrum Illness and Co-Occurring Substance Use Disorder: A Prospective, Multicentric, Real-World Study

BACKGROUND

Dual disorders (DDs) involve the coexistence of a substance use disorder (SUD) with another mental illness, often from the psychotic and affective categories. They are quite common in clinical practice and present significant challenges for both diagnosis and treatment. This study explores the effectiveness of brexpiprazole, a third-generation antipsychotic, in an Italian sample of individuals diagnosed with schizophrenia spectrum disorder and a comorbid SUD.

METHODS

Twenty-four patients, diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and enrolled in several Italian hospitals, underwent a psychometric assessment at baseline (T0) and one month (T1) after starting brexpiprazole treatment administered at a mean dosage of 2 mg/day.

RESULTS

Brexpiprazole demonstrated significant reductions in psychopathological burden (Positive and Negative Syndrome Scale/PANSS total score: p < 0.001). Positive (p = 0.003) and negative (p = 0.028) symptoms, substance cravings (VAS craving: p = 0.039), and aggression (MOAS scale: p = 0.003) were notably reduced. Quality of life improved according to the 36-item Short Form Health Survey (SF-36) subscales (p < 0.005).

CONCLUSIONS

This study provides initial evidence supporting brexpiprazole's efficacy and safety in this complex patient population, with positive effects not only on psychopathology and quality of life, but also on cravings. Further studies involving larger cohorts of subjects and extended follow-up periods are needed.

Presenting Pattern and Psychiatric Comorbidities in Rural versus Urban Substance Dependent Patients: A Hospital-Based Cross-Sectional Study

Background

"Locality" is a significant factor in substance initiation, maintenance, and relapse. The pattern of substance dependence among rural and urban populations varies across studies and is scarcely studied, warranting further research. To compare presenting patterns (sociodemographic and drug-related variables), reasons for substance use, and psychiatric comorbidities (prevalence, type, and severity) between rural and urban substance-dependent groups.

Materials and Methods

This study was a cross-sectional analytical study in a government de-addiction center, including rural and urban patient groups aged 18-65. International Classification of Diseases, Tenth Revision (ICD-10) criteria, and severity of dependence scale were used for diagnosing substance dependence. After detoxification, psychiatric comorbidity was assessed using brief psychiatric rating scale, Young's mania rating scale, and patient health questionnaire - somatic, anxiety, and depression symptoms scale. Post-analysis was performed to assess socioeconomic variables and access to de-addiction services.

Results

The final sample was 500 (250 rural and 250 urban). The post-analysis sample size was 386 (211 rural and 175 urban). The mean age was 38.2 ± 12.4 years, mostly males (n = 495, 99%). Substance frequency was opioids (92%)> benzodiazepines (24.8%) > alcohol (22%) > cannabis (1.6%) for rural and opioids (91.2%) > alcohol (29.6%) > benzodiazepines (14.8%) > cannabis (2%) for urban patients. More than half of patients had comorbid nicotine dependence. Rural patients were more benzodiazepine dependent (P = 0.007), and urban were more opioid + alcohol dependent (P = 0.001). Rural patients had higher age (P = 0.012), less education (P < 0.001), positive family history of substance (P = 0.028), daily wagers, and farmers (P < 0.001) than urban patients who were younger, students (P = 0.002), businessmen and government employed (P < 0.001). Urban patients expended more on drugs (P < 0.001), had higher treatment attempts (P = 0.008), and had better availability and accessibility of de-addiction services (P < 0.001). More rural users initiated substances to "enhance performance," whereas urban ones initiated for "stress relief/novelty" (P < 0.001). For treatment seeking, "External pressure" was a more common reason in urban patients (P < 0.001), who also had more psychiatric comorbidities (P = 0.026).

Conclusion

Significant pattern differences exist between rural and urban substance dependents, warranting emphasis on locality-specific factors for appropriate intervention.

Efficacy of Psychosocial and Psychological Interventions in Addition to Drug Therapy to Improve Global Functioning of Inpatients with Schizophrenia Spectrum and Mood Disorders: A Real-World Observational Study

Introduction and Aim

Psychotic and mood disorders are associated with significant functional impairment, premature mortality, physical morbidity, and great social and economic burden. The aim of this study is to evaluate the effectiveness of psychosocial, psychological, and rehabilitative interventions implemented in an Italian psychiatric inpatient facility, with a focus on patients with schizophrenia spectrum versus those with mood disorders.

Methods

A retrospective observational study was conducted in the psychiatric hospital Villa Maria Pia in Rome, Italy, during 2022. Patients with an established diagnosis of schizophrenia spectrum and mood disorder (ICD-9-CM) were assessed on admission (T0) and at the end of treatment (T1), using the Brief Psychiatric Rating Scale (BPRS) and the Global Assessment of Functioning (GAF). Interventions involved a multidisciplinary team and included individual and group activities. The t-test for independent samples was used to compare continuous variables between groups and Spearman correlation coefficient to calculate correlations between variables.

Results

The study sample consisted of 141 patients, the majority of them being adults (51.3 years ± 12.4) men (F/M= 68/73). Among them, 85 patients (60.3%) actively engaged in psychosocial and rehabilitative interventions and, compared to non-participating individuals, they showed lower functioning and symptoms at discharge (delta GAF was significantly higher among patients who had taken part in the psychosocial activities, t = -2.095; p = 0.038). Considering the index computed (n of interventions/days of hospitalization), the number of psychosocial activities was positively correlated with the improvement in patients' functioning in the sample taking part in activities (r = 0.272, p = 0.012), especially with psychotherapy and support groups (r = 0.202, p = 0.017 and r = 0.188, p = 0.025, respectively). Splitting the total sample into schizophrenia-spectrum disorder (N = 37) and mood disorder (N = 48) groups, the positive correlations between GAF improvement and participation in psychosocial activities were confirmed only in the schizophrenia-spectrum group. These correlations were not significant for symptomatology (BPRS) either in the total or the individual group.

Conclusion

Evidence from our study suggests that inpatient rehabilitation can be effective and useful for people with severe mental disorders. Further investigations are needed to better understand its effectiveness on improving quality of life and social functioning in the long term.

Developmental trajectories in psychiatric disorders: does substance/alcohol use moderate the effects of affective temperaments as moderators of age at onset? A study in post-acute, hospitalized patients with psychotic or DSM-5 bipolar or major depressive disorders

BACKGROUND

Age-at-onset (AAO) affects psychiatric disorder outcome; substance (SUDs) or alcohol use disorders (AUDs) may influence their onset. Affective temperaments may affect early AAO and drug-use proneness. Objectives: To investigate whether SUD/AUD moderated temperamental effects in determining AAO of mental disorders. Methods: We included 300 post-acute inpatients with schizophrenia-spectrum and other psychotic (SSOPDs), major depressive (MDD) or bipolar (BD) disorders (168 men; mean age, 40.63 years ± 11.82 men, 43.21 years ± 12.69 women) with (N = 110) or without (N = 190) SUD/AUD. Patients completed cross-sectionally TEMPS-A. We carried moderation analysis with each regression-significant TEMPS temperament as independent variable, SUD/AUD presence/absence as dichotomous moderator, and AAO as dependent variable. Significance was set at p < 0.05. Results: AAO was lower in patients with SUD/AUD diagnosis than in patients without (23.74 ± 10.09 vs. 27.73 ± 10.35, respectively, p = 0.001, η2 = 0.034). SUD/AUD patients scored higher on the hyperthymic (10.22 ± 4.08, p < 0.001, η2 = 0.069) and irritable (8.26 ± 4.69, p < 0.01, η2 = 0.026) temperaments than nonSUD/AUD patients. Moderation analysis showed only direct effects of irritable (β = -0.55, p < 0.005) and hyperthymic (β = -0.95, p < 0.001) temperaments on AAO and no significant SUD/AUD and interaction effects. Limitations. Cross-sectional design. Conclusions: When irritable and hyperthymic traits prevail over other temperaments, AAO is earlier in SSOPDs, MDD, and BD. SUD/AUD presence/absence does not moderate the relationship between temperament and AAO.
