Medication Exposure and Mortality in Patients With Schizophrenia.

Importance: The use of antipsychotics, antidepressants, and benzodiazepines may influence the risk of mortality in people with schizophrenia. However, many observational studies have not accounted for immortal time bias (ITB), which occurs when there is a period during which patients in the exposed group are necessarily alive and misclassified as exposed (the period between start of follow-up and initiation of drug). Ignoring ITB may lead to misinterpretation of the association between these drugs and mortality.

Reasons Explaining High Emergency Department Use in Patients With Mental Illnesses: Different Staff Perspectives.

For patients with mental illnesses (MIs), emergency departments (EDs) are often the entry point into the healthcare system, or their only resort for quickly accessing mental health treatment. A better understanding of the various barriers justifying high ED use among patients with MIs may help recommend targeted interventions that better meet their needs. This explorative qualitative study aimed to identify such barriers and the solutions brought forth to reduce ED use based on the perspectives of clinicians and managers working in EDs, other hospital departments or the community sector.

The association between task interdependence and participation in decision-making: a moderated mediation model in mental healthcare.

Participation in decision-making is crucial to healthcare workers collaborating across professions. Important correlates of participation in decision-making include task interdependence, informational role self-efficacy, and beliefs in the benefits of interprofessional collaboration. We hypothesised that although task interdependence is directly related to participation in decision-making, the relationship is mediated by informational role self-efficacy.

Emergency Department Use among Patients with Mental Health Problems: Profiles, Correlates, and Outcomes.

Patients with mental health (MH) problems are known to use emergency departments (EDs) frequently. This study identified profiles of ED users and associated these profiles with patient characteristics and outpatient service use, and with subsequent adverse outcomes. A 5-year cohort of 11,682 ED users was investigated (2012-2017), using Quebec (Canada) administrative databases.

Profiles of quality of outpatient care among individuals with mental disorders based on survey and administrative data.

Rationale: Though it is crucial to contribute to patient recovery through access, diversity, continuity and regularity of outpatient care, still today most of these are deemed nonoptimal. Identifying patient profiles based on outpatient service use and quality of care indicators might help formulate more personalized interventions and reduce adverse outcomes.

Aims And Objectives: This study aimed to identify profiles of individuals with mental disorders (MDs) patterned after their outpatient care use and quality of care received, and to link those profiles to individual characteristics and subsequent outcomes.

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.

Characteristics for Low, High and Very High Emergency Department Use for Mental Health Diagnoses from Health Records and Structured Interviews.

Introduction: Patients with mental health diagnoses (MHD) are among the most frequent emergency department (ED) users, suggesting the importance of identifying additional factors associated with their ED use frequency. In this study we assessed various patient sociodemographic and clinical characteristics, and service use associated with low ED users (1-3 visits/year), compared to high (4-7) and very high (8+) ED users with MHD.

Methods: Our study was conducted in four large Quebec (Canada) ED networks.

Profiles of Permanent Supportive Housing Residents Related to Their Housing Conditions, Service Use, and Associated Sociodemographic and Clinical Characteristics.

As permanent supportive housing (PSH) is the main strategy promoted to reduce homelessness, understanding how PSH resident profiles may be differentiated is crucial to the optimization of PSH implementation - and a subject that hasn't been studied yet. This study identified PSH resident profiles based on their housing conditions and service use, associated with their sociodemographic and clinical characteristics. In 2020-2021, 308 PSH residents from Quebec (Canada) were interviewed, with K-means cluster analysis produced to identify profiles and subsequent analyses to compare profiles and PSH resident characteristics.

[Factors encouraging or limiting the use of emergency departments for mental health reasons by frequent users of these services].

Objectives Hospital emergency departments (ED) are often overcrowded, and patients using ED for mental health (MH) reasons contribute in great part to this situation. In Quebec, in 2014-15, 17% of ED users with mental disorders had visited ED at least 4 times for various reasons. These patients' frequent ED use usually reflects the inadequacy of the services provided to them.

Profiles of Emergency Department Users with Psychiatric Disorders Related to Barriers to Outpatient Care.

Emergency department (ED) overcrowding is a growing problem worldwide. High ED users have been historically targeted to reduce ED overcrowding and associated high costs. Patients with psychiatric disorders, including substance-related disorders (SRDs), are among the largest contributors to high ED use.

Treatment with psychostimulants and atomoxetine in people with psychotic disorders: reassessing the risk of clinical deterioration in a real-world setting.

Background: Although attention-deficit hyperactivity disorder (ADHD) is often comorbid with schizophrenia spectrum and other psychotic disorders (SZSPD), concerns about an increased risk of psychotic events have limited its treatment with either psychostimulants or atomoxetine.

Aims: To examine whether the risk of hospital admission for psychosis in people with SZSPD was increased during the year following the introduction of such medications compared with the year before.

Method: This was a retrospective cohort study using Quebec (Canada) administrative health registries, including all Quebec residents with a public prescription drug insurance plan and a diagnosis of psychotic disorder, defined by relevant ICD-9 or ICD-10 codes, who initiated either methylphenidate, amphetamines or atomoxetine, between January 2010 and December 2016, in combination with antipsychotic medication.

Profiles of quality of life among patients using emergency departments for mental health reasons.

Background: This study identified profiles associated with quality of life (QoL) and sociodemographic and clinical characteristics of patients using emergency departments (ED) for mental health reasons and associated these profiles with patient service use.

Methods: Recruited in four Quebec (Canada) ED networks, 299 patients with mental disorders (MD) were surveyed from March 1st, 2021, to May 13th, 2022. Data from medical records were collected and merged with survey data.

Profiles of patients with substance-related disorders who dropped out or not from addiction treatment.

This longitudinal study identified profiles of patients with substance-related disorders (SRD) who did or did not drop out of specialized addiction treatment, integrating various patterns of outpatient service use. Medical administrative databases of Quebec (Canada) were used to investigate a cohort of 16,179 patients with SRD who received specialized addiction treatment. Latent class analysis identified patient profiles, based on multi-year outpatient service use.

Effectiveness of emergency department based interventions for frequent users with mental health issues: A systematic review.

Frequent emergency department (ED) users with mental health issues are particularly vulnerable patients, who often receive insufficient or inadequate outpatient care. This systematic review identified and evaluated studies on ED-based interventions to reduce acute care use by this population, while improving outpatient service use and patient outcomes. Searches were conducted in five databases for studies published between January 1, 2000, and April 30, 2022.

Factors associated with mental health service use during the pandemic: Initiation and barriers.

Background: Scarce are the studies focusing on initiation of new mental health service use (MHSU) and distinguishing individuals who have sought services but have been unsuccessful in accessing these.

Aims: Assessing the factors associated with initiating new MHSU as compared to no MHSU due to self-reported no need, no MHSU due to health system and personal barriers and MHSU using resources already in place.

Methods: The sample included participants ( = 16,435) in the five established regional cohorts of the Canadian Partnership for Tomorrow's Health (CanPath) who responded to the CanPath COVID-19 health surveys (May-December 2020 and January-June 2021).

Variables Associated with Quality of Life Among Individuals Living in Permanent Supportive Housing.

This study identified individual sociodemographic and clinical characteristics and service use patterns associated with quality of life (QoL) among 308 individuals living in permanent supportive housing (PSH) in Québec (Canada). Data were collected between 2020 and 2022, and linear multivariate analyses produced. Results demonstrated that better individual psychosocial conditions were positively associated with higher QoL.

Psychological interventions for loneliness and social isolation among older adults during medical pandemics: a systematic review and meta-analysis.

Objectives: There is little research conducted to systematically synthesize the evidence on psychological interventions for social isolation and loneliness among older adults during medical pandemics. This systematic review aims to address this information gap and provides guidance for planning and implementing interventions to prevent and reduce loneliness and social isolation for older adults, especially during medical pandemics.

Methods: Four electronic databases (EMBASE, PsychoInfo, Medline and Web of Science) and grey literature from 1 January 2000 to 13 September 2022 were searched for eligible studies on loneliness and social isolation.

Acute care utilization and its associated determinants among patients with substance-related disorders: A worldwide systematic review and meta-analysis.

Introduction: Identifying determinants of emergency department (ED) use and hospitalization among patients with substance-related disorders (SRDs) can improve health services to address unmet health needs.

Aim: The present study aimed to identify the prevalence rates of ED use and hospitalization, and their associated determinants among patients with SRDs.

Methods: Studies in English published from January 1, 1995, to December 1, 2022, were searched on PubMed, Scopus, Cochrane Library, and Web of Science to identify primary studies.

Predictors of dropout from treatment among patients using specialized addiction treatment centers.

Objectives: This study investigated the use of outpatient care, and sociodemographic and clinical characteristics of patients with substance-related disorders (SRD) to predict treatment dropout from specialized addiction treatment centers. The study also explored risks of adverse outcomes, frequent emergency department (ED) use (3+ visits/year), and death, associated with treatment dropout within the subsequent 12 months.

Methods: The study examined a cohort of 16,179 patients who completed their last treatment episode for SRD between 2012-13 and 2014-15 (financial years: April 1 to March 31) in 14 specialized addiction treatment centers using Quebec (Canada) health administrative databases.

Mental health service use and associated predisposing, enabling and need factors in community living adults and older adults across Canada.

Objectives: Using Andersen's model of health care seeking behavior, we examined the predisposing, enabling, and need factors associated with mental health service use (MHSU) during the first wave of the COVID-19 pandemic across Canada.

Methods: The sample included n = 45,542 participants in the 5 established regional cohorts of the Canadian Partnership for Tomorrow's Health (CanPath) and who responded to the CanPath COVID-19 health survey (May-December 2020), with complete data on MHSU. Multivariable logistic regression analyses were carried out to study MHSU as a function of predisposing, enabling, and need factors.
