Purpose: Patients with schizophrenia have a higher risk of cannabis use disorder and may be uniquely affected by the legalization of recreational cannabis. This study examined whether cannabis legalization led to changes in acute care utilization among patients with schizophrenia.

Method: Using linked health administrative data, we included adult patients with schizophrenia in Ontario from October 2015 to May 2021 (n = 121,061). We examined the differences in cannabis, psychosis, and mental health-related emergency department (ED) visits over three periods: pre-legalization, legalization of flowers and herbs (phase 1), and legalization of edibles, extracts, and topicals (phase 2) using interrupted time-series methods.

Results: Our study found that phase 1 was associated with decreases in cannabis-related, mental health-related, and cannabis + psychosis-related ED visits among the patients with schizophrenia. Notably, an immediate 25.8% (95% CI 13.8-37.6%) decrease in cannabis-related ED visits was observed in men, and an immediate 18.5% decrease in mental health-related ED visits (95% CI 6.0-31.2%) in women. These decreases were also shown in the comparative ITS models, demonstrating that the changes observed were distinct from trends in the general population. However, phase 2 was not associated with any significant changes.

Conclusions: Despite higher baseline rates of acute care utilization among patients with schizophrenia, cannabis legalization was associated with significant reductions, particularly during phase 1. Our findings suggest that regulatory measures accompanying legalization could enhance the quality and safety of cannabis products, potentially leading to fewer adverse health outcomes in vulnerable patient populations. Further research is needed to optimize healthcare responses for this vulnerable population.

Purpose: To identify, critically appraise, and synthesise the published and grey literature on person-centred crisis support services as an alternative to support in emergency departments (EDs) for people experiencing mental health crises. This scoping review explores the characteristics and outcomes of these services.

Methods: A systematic scoping review was undertaken to identify publications describing person-centred crisis support services and their outcomes. Search strings were applied to multiple databases, and publications were subjected to quality appraisal. The review process was informed by The Joanna Briggs Institute (JBI) Manual for Evidence Synthesis and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR).

Results: Thirteen publications were included in the narrative synthesis, and these considered eight separate crisis support services. The methodological quality of the publications included was limited. Key findings were positive visitors' experiences, high rates of ED deflection, and overlaps between repeat visits, crises prevention, and hospital avoidance. Key recommendations included increasing opening hours and capacity and improving service awareness and accessibility.

Conclusions: The available evidence suggests that person-centred crisis support services are perceived by stakeholders as safe and effective alternatives to EDs for people experiencing mental health crises, providing more timely and appropriate care while reducing ED mental health presentations. Due to the limited quality of the publications included, high-quality research is needed to better understand the model and confirm the findings reported in this review.

Background: People with a non-Western migration background living in Western countries are more likely to experience psychiatric problems and have more severe symptoms when they do. Patients of non-Western origin also have more unmet needs for care. This study focuses on differences between Western and non-Western patients in care needs being met during the course of mental health treatment.

Methods: The care needs of 1099 patients, 39% with and 61% without a non-Western migration background, recorded between 2017 and 2020 in Flexible Assertive Community Treatment, were compared.

Results: Non-Western migrants more often received psychotic disorder diagnoses, had more socio-economic problems, met, unmet and total needs for care and experienced less reduction in unmet needs during treatment. This was specifically the case for the rehabilitation areas: daily activities, treatment information, basic education, paid work and meaningful life and recovery. After controlling for socio-economic factors and diagnosis, group differences in change in number of unmet needs were no longer significant. However, the reduction in unmet needs in the areas of basic education, paid work and meaningful life and recovery remained significantly smaller for non-Western patients.

Conclusions and implications for practice: Except for the rehabilitation domains of basic education, paid work and meaningful life, the disadvantages in resolving the care needs of patients with a non-Western migration background do not remain significant after taking into account socioeconomic factors and diagnosis. Collaboration of mental health care and the social domain is warranted to improve socio-economic factors for patients with a non-Western migration background, to better address their unmet needs for care.

Background: Shared decision-making (SDM) is of increasing importance in mental health care, however, large studies on the effects of SDM in bipolar disorder (BD) are scarce.

Aim: To gain insight into the relationships between SDM, guideline concordance of treatments in everyday practice, satisfaction with care, and medication adherence in BD.

Method: In a nationwide observational study on the treatment of BD, patients were asked questions about their involvement in treatment. These questions were clustered according to the three-talk model (TTM) for SDM, which involves team talk, option talk, and decision talk. A composite concordance score for multimodal treatments was made, and satisfaction with care (score 1 to 10) and medication adherence (DAI-10) were measured.

Results: 839 patients with BD from various outpatient treatment centers were included. Patients were highly involved in decision-making. In multiple regression, team talk was significantly positively associated with guideline concordance (b = 5.10, p = .045), and decision talk was positively associated with satisfaction with care (b = 0.82, p < .001) and medication adherence (b = 1.18, p = .003).

Conclusion: Positive associations were found between SDM, guideline concordance, satisfaction with care, and medication adherence, suggesting that investing in these steps of the decision-making process together with patients and their significant others, will help to improve quality of care.

Purpose: Brain health is a dynamic state involving cognitive, emotional, and motor domains. Measuring brain health is a challenge owing to the uncertainty as to whether it is one or many constructs. This study aimed to contribute evidence for brain health as a unified construct by estimating the strength of relationships between and among patient-reported items related to the brain health construct in a population with brain vulnerability owing to HIV.

Methods: Data for this cross-sectional analysis came from a Canadian cohort of people aging with HIV. The sample included 710 men recruited between 2014 and 2016 from five Canadian cities. A network analysis was conducted with 30 items selected from the brain-related domains of fatigue, cognition, depression, sleep, anxiety, and motivation. Node centrality measures were used to determine the most critical items in the network.

Results: The network showed small-world properties, that is, most nodes can be reached from other nodes with few hops," indicating strong connectivity. The most central symptoms were "How much do you enjoy life?" and "How often do you have negative feelings?".

Conclusion: The small-world properties of the network structure indicate that brain health items are interconnected and may be influenced by shared underlying factors. The centrality indices suggest that items related to enjoyment of life and negative feelings may be particularly important for understanding brain health in this population. Future research should aim to replicate these findings in larger and more diverse samples to confirm their robustness and generalizability.

Purpose: To identify trajectory groups of work disability (WD), including sick leave and disability pension, and unemployment three years before and six years (from Y-3 to Y + 6) after a common mental disorder (CMD) diagnosis and to investigate associations of socio-demographic, work-related and clinical factors with trajectory membership.

Methods: A longitudinal nationwide register-based study was conducted including individuals aged 22-29 years, gainfully employed in the private sector, with a CMD diagnosis in specialised healthcare or prescribed antidepressant (N = 12,121) in 2014 (Year 0/Y0), with follow-up from Y-3 to Y + 6. Group-based trajectory analyses identified groups of individuals who followed similar trajectories of months of WD and unemployment, respectively. Multinomial logistic regression determined associations between socio-demographic, work-related and clinical factors and trajectory membership.

Results: In the CMD group, we identified three trajectory groups, each for WD and unemployment. Only 7% individuals belonged to a 'Fluctuant high' trajectory group with four months of WD in Y0, which peaked at 7 months in Y + 3 and reduced to 5 months in Y + 6. For unemployment, 15% belonged to an 'Increasing medium' trajectory group that steadily increased from 1.3 months in Y0 to 2.6 months in Y + 6. Sex, educational level and musculoskeletal disorders for WD, and educational level, living area and occupational class for unemployment, influentially determined the variance across the CMD trajectory groups.

Conclusions: Specific vulnerable groups regarding unfavourable WD (women, low education and musculoskeletal disorders) and unemployment (manual work, low education and rural residence) trajectories require special attention regarding their return-to-work process following a CMD diagnosis.

Purpose: To describe temporal trends in inpatient care use for adult mental disorders in Czechia from 1994 until 2015.

Methods: Data from the nationwide register of inpatient care use and yearly census data were used to calculate (a) yearly admissions rates, (b) median length of stay, and (c) standardized inpatient-years for adult mental disorders (ICD-10 codes F0-F6] or G30). Segmented regressions were used to analyze age- and sex-specific temporal trends.

Results: Admission rates were increasing in adults (average annual percent change = 0.51; 95% confidence interval = 0.16 to 0.86 for females and 1.01; 0.63 to 1.40 for males) and adolescents and emerging adults (3.27; 2.57 to 3.97 for females and 2.98; 2.08 to 3.88 for males), whereas in seniors, the trend was stable (1.22; -0.31 to 2.73 for females and 1.35; -0.30 to 2.98 for males). The median length of stay for studied mental disorders decreased across all age and sex strata except for a stable trend in male adolescents and emerging adults (-0.96; -2.02 to 0.10). Standardized inpatient-years were decreasing in adults of both sexes (-0.85; -1.42 to -0.28 for females and -0.87; -1.19 to -0.56 for males), increasing in female adolescents and emerging adults (0.95; 0.42 to 1.47), and stable in the remaining strata.

Conclusion: Psychiatric hospital admissions were increasing or stable coupled with considerable reductions in median length of stay, suggesting that inpatient episodes for adult mental disorders have become more frequent and shorter over time. The overall psychiatric inpatient care use was decreasing or stable in adults and seniors, potentially implying a gradual shift away from hospital-based care.

Objectives: To examine the association between perception of one's social environment (in terms of residential attachment and neighborhood trust) and loneliness among the oldest old and whether these associations differ by living arrangement.

Methods: We used data from the nationally representative "Old Age in Germany (D80+)" study that included individuals residing in private households and institutionalized settings. The analytic sample was 9,621 individuals (average age: 85.5 years, SD: 4.1 years; 62% female). Data collection took place from November 2020 to April 2021. Multiple linear regressions were conducted with adjustment for relevant covariates.

Results: Higher residential attachment (β=-0.02, p < .05) and higher neighborhood trust (β=-0.12, p < .001) were associated with less loneliness. The latter association was moderated by living arrangement (β=-0.09, p = .04) such that the association between neighborhood trust and loneliness was stronger among individuals living in institutionalized settings compared to individuals in private households.

Conclusion: Greater residential attachment and neighborhood trust, particularly among individuals living in institutionalized settings, are associated with less loneliness among the oldest old. Finding ways to improve perceived attachment and trust may assist in avoiding loneliness among older individuals.

Purpose: In China, individuals with substance use disorders (SUD) face severe stigma, but reliable stigma assessment tool is lacking. Therefore, this study aimed to validate the Chinese version of the Substance Use Stigma Mechanism Scale (SU-SMS-C) and set its cut-off point.

Methods: We recruited 1005 individuals with SUDs from Chinese rehabilitation centers. These participants completed a battery of questionnaires that included the SU-SMS-C, The Multidimensional Scale of Perceived Social Support (MSPSS), Center for Epidemiologic Studies Depression Scale (CES-D), General Self-Efficacy Scale (GSES), and Perceived Devaluation and Discrimination (PDD). Confirmatory factor analysis was used to assess the construct validity of the scale. Additionally, the Naive Bayes classifier was used to establish the cut-off point for the SU-SMS-C. We additionally explored the correlation between patient demographic characteristics and stigma.

Results: A confirmatory factor analysis was utilized, revealing a second-order five-factor model. Based on the Naive Bayes classifier, the area under the receiver operating characteristic (AUCROC) of 0.746, the cut-off point for the SU-SMS-C was established at 44.5. The prevalence of stigma observed in the study population was 49.05%. Significant disparities were observed in the distribution of stigma across genders, with males experiencing more pronounced stigma than females. Moreover, patients consuming different primary substances reported diverse levels of stigma. Notably, those primarily using heroin endured a higher degree of stigma than users of other substances.

Conclusion: The study is the first to identify a cut-off point for the SU-SMS-C by Naive Bayes classifier, bridging a major gap in stigma measurement research. SU-SMS-C may help treat and manage SUDs by reducing stigma.

Purpose: Perinatal depression significantly impacts maternal and child health, with further complexities arising during the COVID-19 pandemic. This review is the first to comprehensively synthesize evidence on the prevalence of perinatal depression and its associated risk factors in Low- and Middle-Income Countries (LMICs) during the pandemic period.

Methods: The study protocol was registered in PROSPERO (CRD42022326991). This review followed the Joanna Briggs Institute (JBI) guideline for prevalence studies. A comprehensive literature search was conducted in six databases: PubMed, Scopus, Web of Science, PsycInfo, CINAHL, and ProQuest. Pooled prevalence estimates were computed for both prenatal and postnatal depression. Identified risk factors were summarized narratively.

Results: A total of 5169 studies were screened, out of which 58 were included in the narrative review and 48 [prenatal (n = 36) and postnatal (n = 17)] were included in the meta-analysis. The pooled depression prevalence for prenatal women was 23% (95% CI: 19-27%), and for the postnatal women was 23% (95% CI: 18-30%). Maternal age, education, perceived fear of COVID-19 infection, week of pregnancy, pregnancy complications, and social and family support were identified as associated risk factors for depression.

Conclusions: Our review demonstrates an increased prevalence of perinatal depression during the COVID-19 pandemic in LMICs. It sheds light on the significant burden faced by pregnant and postnatal women and emphasizes the necessity for targeted interventions during the ongoing and potential future crisis.
