Intensive Case Management for Severe Mental Illness

The schizophrenia syndrome, circa 2024: What we know and how that informs its nature

With new data about different aspects of schizophrenia being continually generated, it becomes necessary to periodically revisit exactly what we know. Along with a need to review what we currently know about schizophrenia, there is an equal imperative to evaluate the construct itself. With these objectives, we undertook an iterative, multi-phase process involving fifty international experts in the field, with each step building on learnings from the prior one. This review assembles currently established findings about schizophrenia (construct, etiology, pathophysiology, clinical expression, treatment) and posits what they reveal about its nature. Schizophrenia is a heritable, complex, multi-dimensional syndrome with varying degrees of psychotic, negative, cognitive, mood, and motor manifestations. The illness exhibits a remitting and relapsing course, with varying degrees of recovery among affected individuals with most experiencing significant social and functional impairment. Genetic risk factors likely include thousands of common genetic variants that each have a small impact on an individual's risk and a plethora of rare gene variants that have a larger individual impact on risk. Their biological effects are concentrated in the brain and many of the same variants also increase the risk of other psychiatric disorders such as bipolar disorder, autism, and other neurodevelopmental conditions. Environmental risk factors include but are not limited to urban residence in childhood, migration, older paternal age at birth, cannabis use, childhood trauma, antenatal maternal infection, and perinatal hypoxia. Structural, functional, and neurochemical brain alterations implicate multiple regions and functional circuits. Dopamine D-2 receptor antagonists and partial agonists improve psychotic symptoms and reduce risk of relapse. Certain psychological and psychosocial interventions are beneficial. Early intervention can reduce treatment delay and improve outcomes. Schizophrenia is increasingly considered to be a heterogeneous syndrome and not a singular disease entity. There is no necessary or sufficient etiology, pathology, set of clinical features, or treatment that fully circumscribes this syndrome. A single, common pathophysiological pathway appears unlikely. The boundaries of schizophrenia remain fuzzy, suggesting the absence of a categorical fit and need to reconceptualize it as a broader, multi-dimensional and/or spectrum construct.

Integrated Health and Social Services for People With Chronic Mental Health Problems: People Are More Important Than Processes. Insights From a Multiple Case Study in Swedish Psychiatry

Three mental health organizations, one merged with, one formally cooperating with, and one without formal links to social services were analyzed through the experience of staff, patients and relatives in order to elucidate what approaches best promoted service coordination. Seventeen staff and eight patients or relatives, recruited from the three organizations, participated in semi-structured interviews, guided by pre-selected categories derived from previous research about coordination and care processes. Directed content analysis was used to identify and categorize meaning units. Both staff and patients raised the same concerns. Organized collaboration between psychiatric care and social services addressed only some of patients' challenges. More important was patient access to financial and social assistance. The organizational arrangements were not referred to, whereas case management was seen as crucial. In many instances relatives have to act as case managers. Service integration in mental health has to include, in addition to social services, other authorities like social insurance and employment agencies. A case manager knowledgeable about all welfare services is best positioned to promote that “extended integration”. Relatives often have to take this responsibility to support this fragile group of patients. This observed importance of case management is supported by previous research in mental health and primary care. The role of relatives should be acknowledged and supported by those services.

Specialist nursing case management support for carers of people with dementia: A qualitative study comparing experiences of carers with and without Admiral Nursing

Carers of people with dementia can experience reduced health and well-being, but little is known about how best to support them. There is some evidence to suggest that case management may improve outcomes for carers but less evidence about the features of case management services that can effectively support carers of people with dementia. Admiral Nursing operates a case management approach staffed by specialist nurses and is the only service of its kind in the United Kingdom dedicated to helping people with dementia and their carers. This paper reports qualitative findings from a mixed methods study of Admiral Nursing. For the qualitative strand of the project, data were collected in focus groups and in-depth interviews with carers of people with dementia (n = 35) and analysed thematically using the framework approach. The aim of this analysis was to understand differences between the experiences of the carers in our sample with and without Admiral Nursing, applying Freeman's model of continuity of care (Freeman et al., Continuity of care, 2000). Participants who had received Admiral Nursing were recruited from two geographical locations and carers without experience of this service were recruited from two different areas. We found that carers in our sample felt 'supported' in circumstances where they received an ongoing service from an Admiral Nurse or other professional with expertise in dementia who was able to develop a meaningful relationship with them over time. We conclude that ongoing support, expertise in dementia and a meaningful relationship are key features of relationship continuity common in carers' reports of feeling supported. Specialist nurses are well placed to provide this continuity.

Psychosocial interventions for community-dwelling individuals with schizophrenia: study protocol for a systematic review and meta-analysis

INTRODUCTION

Despite the recent global mental health movement of the transition from hospital-centred to integrated community-based services, comprehensive evidence of psychosocial interventions focusing on community-dwelling individuals with schizophrenia is still lacking. To overcome this gap in the current knowledge, we will conduct a systematic review and meta-analysis to assess the efficacy of all types of psychosocial interventions for community-dwelling (non-hospitalised) individuals with schizophrenia when compared with non-active control conditions (eg, treatment as usual).

METHODS AND ANALYSIS

This study protocol has been developed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. By March 2022, the following sources will have been searched, without restrictions for language or publication period: Embase, PubMed, PsycINFO, CINAHL, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. We will also try to identify other potentially eligible studies by searching the reference lists of included studies, other relevant systematic reviews and grey literature. All relevant randomised controlled trials from both high-income and low-income to middle-income countries will be allowed. Two independent reviewers will conduct the selection/screening of studies, data extraction and methodological quality assessment of included studies. The primary outcomes are quality of life and psychiatric hospital admission. Standard pairwise meta-analyses with a random-effects model will be conducted. Subgroup and sensitivity analyses will be performed to assess the robustness of the findings. Risk of bias will be assessed with the Revised Cochrane Risk-of-Bias Tool for Randomised Trials. The Grades of Recommendation Assessment, Development and Evaluation approach will be used to assess the quality of evidence.

ETHICS AND DISSEMINATION

Ethics approval is not required for this study. The study findings will be disseminated through conference presentations as well as peer-reviewed publications.

Rates and Correlates of Suicidality in VA Intensive Case Management Programs

There has been extensive concern about suicide among veterans, but no study has examined rates and correlates of suicidality in the highly vulnerable group of veterans receiving Veterans Health Administration (VHA) intensive case management services. Veterans participating in a national program evaluation were surveyed at the time of program entry and 6 months later. Sociodemographic and clinical characteristics were documented along with elements of program service delivery. Chi square tests were used to compare rates of suicidality (defined as either having made or threatened an attempt) at baseline and at the 6-month follow-up. Analysis of variance was also used to compare suicidal and non-suicidal veterans at follow-up. Logistic regression analysis was then used to identify independent correlates of suicidality 6 months after program entry. Among the 9921 veterans who later completed follow-up assessments 989 (10.0%) had reported suicidal behavior at program entry as compared to only 250 (2.51%) at 6 months (p < 0.0001). Multivariable logistic regression analysis showed suicidality at 6 months to be associated with suicidality at admission, increased subjective distress on the Brief Symptom Inventory (especially on depression items), violent behavior and decreased quality of life since admission, along with a greater likelihood of receiving crisis intervention, but not other services. Among veterans receiving intensive case management services from VHA, suicidal behavior declined by 75% from admission to 6 months (10-2.5%) and was associated with suicidality prior to program entry, worsening subjective symptoms and greater receipt of crisis intervention services.

High utilisers of emergency departments: the profile and journey of patients with mental health issues

OBJECTIVE

Frequent presenters to the Emergency Department (ED) are known to have complex physical, behavioural and social needs. The study aimed to analyse the system's behaviour to generate new insights into ED high utilisers with complex mental health issues.

METHODS

A retrospective cohort study of the ED presentations of 200 high utilisers during a 12-month period was conducted. Analyses included psychiatric diagnoses, re-presentation rates, cost-benefit analysis of services and patient journey maps to illustrate the patient experience.

RESULTS

The profiled high utilisers represented nearly a quarter of total ED mental health presentations and were more likely to be single and unemployed. Diagnostically, Borderline Personality Disorder and Schizophrenia predominated. The re-presentation rate was high (70% within 28 days) and mental health attributable costs represented nearly three quarters of total health costs.

CONCLUSION

The study revealed a disintegrated service system for ED high utilisers with mental health issues, resulting in suboptimal clinical outcomes and substantial costs. To deliver value-based mental healthcare our lessons were; (1) stabilise the system's interaction with the patient by ensuring service responses are consistent with their enhanced management plan (2) all the system's parts channel the patient into various support services including psychological treatment with one therapist.KEY POINTSThe top 200 high utilisers presented to emergency 1928 times within 12 monthsThe re-presentation rate amongst the study's cohort was high (70% within 28 days)A high prevalence of BPD and schizophrenia was noted for this cohortThe study reveals a disintegrated service system for ED high utilisers, resulting in suboptimal clinical outcomes and substantial costs for the serviceA need for early identification, consistency in service responses and various support services to be provided by the hospital including psychological treatment.

The Cal-DSH diversion guidelines

The Cal-DSH Diversion Guidelines provide 10 general guidelines that jurisdictions should consider when developing diversion programs for individuals with a serious mental illness (SMI) who become involved in the criminal justice system. Screening for SMI in a jail setting is reviewed. In addition, important treatment interventions for SMI and substance use disorders are highlighted with the need to address criminogenic risk factors highlighted.

Improved Rehabilitation Outcomes for Persons With and Without Problematic Substance Use After 2 Years With Assertive Community Treatment-A Prospective Study of Patients With Severe Mental Illness in 12 Norwegian ACT Teams

Background: Persons with severe mental illness often face difficulties in accessing and receiving adequate services enabling them to live independently. Many have co-occurring substance use problems that increase the risk of adverse outcomes. Community-based service models have been implemented around the world, including assertive community treatment (ACT), but the knowledge of rehabilitation outcomes in different subgroups is limited. We aimed to explore rehabilitation outcomes among patients suffering severe mental illness with and without substance use problems who had received ACT services for at least 2 years. Additionally, we compared differences in changes between the two groups. Methods: A total of 142 patients who received services for 2 years from the first 12 Norwegian ACT teams were included. Eighty-four (59%) had problematic substance use, while 58 (41%) did not. Data regarding housing, activity, symptoms, functioning, and subjective quality of life were collected upon enrollment into ACT and at 2 years of follow-up. Clinician-rated scales and self-report questionnaires were used. Changes within the two groups and differences in change between the groups were assessed using generalized linear mixed models. Results: Both groups were more likely to have good housing, higher level of functioning, and less anxiety and depressive symptoms after 2 years. The odds of good housing among participants with problematic substance use increased only after adjusting for age and gender. Participants with problematic substance use had less severe symptoms, particularly negative and manic symptoms, while participants without problematic substance use reported improved satisfaction with life in general. Neither group experienced a change in having a meaningful daily activity, positive symptoms, practical and social functioning, or subjective quality of life. The reduction of manic symptoms in the substance use group was the only difference between the groups. Conclusion: After 2 years, patients with and without problematic substance use experienced improvements in several important domains. Furthermore, the improvements were similar in both groups for most outcomes. This may suggest that ACT has a place in the continued effort toward integrated and comprehensive community services empowering patients with severe mental illness to achieve and sustain an independent life, including marginalized groups with severe substance use.

Optimization of Antipsychotic and Benzodiazepine Drugs in Patients with Severe Mental Disorders in an Intensive Case Management Program

The Intensive Case Management (ICM) model is a community-based program for people with severe mental illness that may reduce hospitalization and increase retention in care. The aims of this study were to analyze changes in the antipsychotic and benzodiazepine dosage in 106 patients who participated in an Individualized Service Program based on the ICM model for at least 6 months and to assess the change in the number of patients taking a high or very high dose of an antipsychotic drug and the number receiving antipsychotic polytherapy. Both the average daily dose of antipsychotic and benzodiazepine drugs and the number of patients with high doses of antipsychotic and more than one antipsychotic drug decreased significantly. Implementing the ICM program in patients with severe mental illness could help to decrease adverse drug effects and health care expenditures.

Exploring the Experiences of Persons Who Frequently Visit the Emergency Department for Mental Health-Related Reasons

In this qualitative study, the experiences of persons who frequently visit the emergency department (ED) for mental health-related reasons were explored. Interpretive Description guided the design, and data were collected through interviews with 10 adults who made 12+ ED visits within a 1-year time frame (2015). Thematic analysis was used to analyze data inductively. The participants' experiences were described with the help of three themes emerging from the data: The Experience, The Providers, and Protective Factors. The participants felt compelled to come to hospital. For them, every visit was necessary, and dismissal of their needs by staff was interpreted as disrespect and prejudice. We noted differences in ED utilization patterns according to psychiatric diagnosis, and more research is needed to explore the phenomenon of frequent use by particular patient populations. Furthermore, health care providers implementing interventions designed to improve emergency care should consider tailored approaches rather than a one-size-fits-all strategy.
