Ten-Year Outcomes of First-Episode Psychoses in the MRC ÆSOP-10 Study

Spatial metabolomics in mental disorders and traditional Chinese medicine: a review

Spatial metabolomics is an emerging technology that integrates mass spectrometry imaging (MSI) with metabolomics, offering a novel visual perspective for traditional metabolomics analysis. This technology enables in-depth analysis in three dimensions: qualitative, quantitative, and localization of metabolites. Spatial metabolomics precisely reflects the characteristics of metabolic network changes in metabolites within entire tissues or specific micro-regions. It provides a detailed understanding of the pharmacodynamic material basis and mechanisms of action. These capabilities suggest that spatial metabolomics can offer significant technical support for studying the complex pathophysiology of mental disorders. Although the mechanisms underlying mental disorders have been reviewed multiple times, this paper provides a comprehensive comparison between traditional metabolomics and spatial metabolomics. It also summarizes the latest progress and challenges of applying spatial metabolomics to the study of mental disorders and traditional Chinese medicine.

Cannabidiol attenuates prepulse inhibition disruption by facilitating TRPV1 and 5-HT1A receptor-mediated neurotransmission

Individuals with schizophrenia (SCZ) often present sensorimotor gating impairments that can be investigated by the prepulse inhibition test (PPI). PPI disruption can be mimicked experimentally with psychostimulants such as amphetamine and attenuated/reversed by antipsychotics. Cannabidiol (CBD), the main non-psychotomimetic component of the Cannabis sativa plant, produces antipsychotic-like effects in clinical and preclinical studies. CBD can interact with many pharmacological targets, but the mechanisms involved in its antipsychotic activity are unclear. Using amphetamine-induced PPI disruption in mice, we investigated the involvement of four CBD potential pharmacological targets (CB1, CB2 TRPV1, and 5-HT1A receptors) in its antipsychotic properties. CBD effects were blocked by the TRPV1 antagonist capsazepine and, to a greater extent, by the 5-HT1A receptor antagonist WAY100635. No effect was observed with the CB1 (AM251) or CB2 (AM630) receptor antagonists. These results corroborate findings showing the antipsychotic effects of CBD in the PPI model and indicate that they involve the participation of TRPV1 and 5-HT1A receptors.

Effectiveness of psychological interventions for carers of patients with severe mental illness (SMI): a systematic review

OBJECTIVES

Interventions for carers of patients with severe mental illness (SMI) are effective in improving patient outcomes. This review examined the effectiveness of psychological interventions or support designed to help carers of patients with SMI.

DESIGN

A systematic review of randomised controlled trials (RCTs) was conducted. Study selection, data abstraction and risk of bias assessments were independently conducted and duplicated. The reporting of this review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

DATA SOURCES

CINAHL, CENTRAL, EMBASE, Medline and PsycINFO were searched from inception to 30 April 2024.

ELIGIBILITY CRITERIA

Only studies using an RCT were considered. All other research designs were excluded. The included population was carers over 18 caring for a patient with SMI. Any psychological, psychosocial or psychoeducational interventions were included. Patients under 18, diagnosed with dementia or learning disabilities comorbidity, were excluded.

DATA EXTRACTION AND SYNTHESIS

Study characteristics and outcome data (mean and SD) for each included study were collected. Review Manager (RevMan) was used to manage the data. Meta-analysis was not considered appropriate due to the heterogeneity of the included studies. The results were presented as a narrative synthesis.

RESULTS

This review included 3869 participants from 32 RCTs and demonstrated a beneficial effect of psychological interventions for carers. Psychoeducation was widely used and the most evaluated intervention for carers.

CONCLUSIONS

Psychological interventions for carers are beneficial in helping to reduce negative outcomes and enhance positive outcomes. Future research could focus on exploring the impact of interventions on less evaluated outcomes such as depressive and anxiety symptoms.

Development and initial evaluation of a clinical prediction model for risk of treatment resistance in first-episode psychosis: Schizophrenia Prediction of Resistance to Treatment (SPIRIT)

BACKGROUND

A clinical tool to estimate the risk of treatment-resistant schizophrenia (TRS) in people with first-episode psychosis (FEP) would inform early detection of TRS and overcome the delay of up to 5 years in starting TRS medication.

AIMS

To develop and evaluate a model that could predict the risk of TRS in routine clinical practice.

METHOD

We used data from two UK-based FEP cohorts (GAP and AESOP-10) to develop and internally validate a prognostic model that supports identification of patients at high-risk of TRS soon after FEP diagnosis. Using sociodemographic and clinical predictors, a model for predicting risk of TRS was developed based on penalised logistic regression, with missing data handled using multiple imputation. Internal validation was undertaken via bootstrapping, obtaining optimism-adjusted estimates of the model's performance. Interviews and focus groups with clinicians were conducted to establish clinically relevant risk thresholds and understand the acceptability and perceived utility of the model.

RESULTS

We included seven factors in the prediction model that are predominantly assessed in clinical practice in patients with FEP. The model predicted treatment resistance among the 1081 patients with reasonable accuracy; the model's C-statistic was 0.727 (95% CI 0.723-0.732) prior to shrinkage and 0.687 after adjustment for optimism. Calibration was good (expected/observed ratio: 0.999; calibration-in-the-large: 0.000584) after adjustment for optimism.

CONCLUSIONS

We developed and internally validated a prediction model with reasonably good predictive metrics. Clinicians, patients and carers were involved in the development process. External validation of the tool is needed followed by co-design methodology to support implementation in early intervention services.

Relationship Quality Among Persons with Serious Mental Illness and Their Relatives: Rates and Correlates

Supportive family relationships for persons with serious mental illness (SMI) are correlated with positive functional, health and mental health outcomes and are essential to the recovery process. However, there has been a dearth of research on positive family dynamics. Using multivariate logistic regression with a U.S. community-recruited sample of persons with SMI (N = 523), we examined the extent to which demographics, clinical characteristics, and supportive and problematic relationship interactions were associated with relationship quality with reference relatives (RR). Secondarily, we tested whether the relationship between routine limit-setting practices by RR toward participants and relationship quality was significantly mediated by perceived emotional overinvolvement using Baron and Kenny's four step method. High levels of relationship quality were reported by two-thirds of the sample. Relationship quality was positively associated with frequency of contact between participants and RR, participants helping RR with activities of daily living, and caregiving provided by RR to participants. High relationship quality was negatively associated with RR being parents or other family members (compared to romantic partners), perceived emotional overinvolvement of RR, and psychological abuse by RR toward participants. Clinical and demographic characteristics were not associated with relationship quality. Perceived emotional overinvolvement was found to be a mediator between routine limit-setting practices and relationship quality. These results can help direct clinicians in targeting factors that will likely enhance the process of recovery.

Family Empowerment Strategies for Relapse Prevention in Individuals With Schizophrenia: A Scoping Review

The current scoping review aimed to provide an overview of family empowerment strategies used in relapse prevention among individuals with schizophrenia. Three major topics were explored: (a) the family empowerment model used in relapse prevention among individuals with schizophrenia; (b) family intervention strategies; and (c) special considerations for integrating family empowerment in relapse prevention among individuals with schizophrenia. There is a need to identify and use family resources and strengths, such as acceptance of schizophrenia, development of spirituality, involvement in daily activities, and understanding of behaviors that exacerbate symptoms, to reduce relapse risk. The family empowerment paradigm incorporates new information and coping skills, family support, meaning-making, life objectives, self-reflection, and good family experiences. Families as agents of care at home should be provided with stress management and family psychoeducation to improve family resilience. Further research is needed to understand family empowerment and develop comprehensive guidelines regarding relapse prevention management among individuals with schizophrenia.

A Thematic Analysis Investigating the Inaugural Psychosis REACH Family Ambassador Peer Training Program

Purpose

Caregivers of loved ones with psychosis are tasked with navigating a barren care landscape for their loved ones and for themselves. The dearth of resources they face has a negative impact on outcomes for caregivers and their loved ones. The Psychosis REACH program, based on principles from Cognitive Behavioral Therapy for psychosis was developed as a community-based resource for families to address this care gap. A role for family peers called the Psychosis REACH Family Ambassadors (pRFAs) was developed to reinforce skill learning for caregivers by utilizing a task-sharing approach. This qualitative study sought to better understand pRFAs' experiences in the inaugural training cohort of this program.

Patients and Methods

Eleven pRFAs participated in semi-structured interviews with research coordinators via teleconference. Questions assessed the quality of the training, challenges and facilitators experienced in their role, and ways in which the program could be improved and expanded. Using thematic analysis, members of the research team coded interviews individually, discussed codes until consensus was reached, and iteratively developed themes based on codes that clustered based on meaning or content.

Results

This process identified 5 key themes: The development of hope and recovery, the development of solidarity networks, the challenges of navigating boundaries, preferred pedagogical strategies, and the need for more support.

Conclusion

Overall, the themes developed from this qualitative analysis demonstrate the value and feasibility of developing a caregiver peer network of pRFAs trained in recovery-oriented care and CBTp-informed skills to support other caregivers. Additionally, they highlight the challenges associated with being in the role of a pRFA and further efforts needed to align training content and learning management systems to the needs of pRFA trainees. These findings highlight the importance of expanding access to family peer training programs for the wellbeing of caregivers and loved ones with psychosis alike.

Effects of an eating club for people with a psychotic disorder on personal recovery: Results of a randomized controlled trial

BACKGROUND AND OBJECTIVES

Many people with a psychotic disorder are coping with severe psychosocial limitations related to their illness. The current randomized controlled trial (RCT) investigates the effects of an eating club intervention (HospitalitY (HY)) aimed to improve personal and societal recovery.

METHODS

In 15 biweekly sessions participants received individual home-based skill training and guided peer support sessions in groups of three participants from a trained nurse. A multi-center RCT was conducted (intended sample size: n = 84; n = 7 per block) in patients with a diagnosis of schizophrenia spectrum receiving community treatment. HospitalitY was compared to a Waiting List Control (WLC) condition at three time points (baseline, end-of-treatment (8 months) and follow-up (12 months)) using personal recovery as primary outcome and loneliness, social support, self-stigma, self-esteem, social skills, (social) functioning, independency competence, and psychopathology as secondary outcomes. Outcomes were evaluated with a mixed modeling statistical procedure.

RESULTS

The HY-intervention had no significant effects on personal recovery or secondary outcomes. More attendance was associated with higher scores on social functioning.

LIMITATIONS

With N = 43 participants included, power was insufficient. Seven HY-groups were started, from which three discontinued before the sixth meeting, one HY group stopped due the start of the COVID-19 pandemic.

CONCLUSIONS

Despite a promising pilot study on feasibility, the current RCT did not show any effects of the HY intervention. A mixed qualitative-quantitative research methods might be more appropriate for researching the HospitalitY-intervention to investigate what social and cognitive processes are at play in this peer guided social intervention.

User-Centered Development of Bolster, an mHealth Intervention for Early Psychosis Caregivers: Needs Assessment, Prototyping, and Field Trial

BACKGROUND

Caregivers play a critical role in the treatment and recovery of youth and young adults at risk for psychosis. Caregivers often report feeling isolated, overwhelmed, and lacking in resources. Mobile health (mHealth) has the potential to provide scalable, accessible, and in-the-moment support to caregivers. To date, few if any mHealth resources have been developed specifically for this population.

OBJECTIVE

The aim of this study was to conduct user-centered design and testing of an mHealth intervention to support early psychosis caregivers.

METHODS

We conducted a multiphase user-centered development process to develop the Bolster mobile app. In phase 1, a total of 21 caregivers were recruited to participate in a qualitative needs assessment and respond to an initial prototype of the Bolster platform. Content analysis was used to identify key needs and design objectives, which guided the development of the Bolster mobile app. In phase 2, a total of 11 caregivers were recruited to participate in a 1-week field trial wherein they provided qualitative and quantitative feedback regarding the usability and acceptability of Bolster; in addition, they provided baseline and posttest assessments of the measures of distress, illness appraisals, and family communication.

RESULTS

In phase 1, participants identified psychoeducation, communication coaching, a guide to seeking services, and support for coping as areas to address. Live prototype interaction sessions led to multiple design objectives, including ensuring that messages from the platform were actionable and tailored to the caregiver experience, delivering messages in multiple modalities (eg, video and text), and eliminating a messaging-style interface. These conclusions were used to develop the final version of Bolster tested in the field trial. In phase 2, of the 11 caregivers, 10 (91%) reported that they would use Bolster if they had access to it and would recommend it to another caregiver. They also reported marked changes in their appraisals of illness (Cohen d=0.55-0.68), distress (Cohen d=1.77), and expressed emotion (Cohen d=0.52).

CONCLUSIONS

To our knowledge, this study is the first to design an mHealth intervention specifically for early psychosis caregivers. Preliminary data suggest that Bolster is usable, acceptable, and promising to improve key targets and outcomes. A future fully powered clinical trial will help determine whether mHealth can reduce caregiver burdens and increase engagement in services among individuals affected by psychosis.

Long-acting antipsychotics in the treatment of schizophrenia: opportunities and challenges

INTRODUCTION

Maintenance antipsychotic treatment improves multiple outcomes in people with schizophrenia. These benefits are challenged by medication nonadherence, which is a common occurrence. Long-acting injectable antipsychotic (LAI) formulations were developed to reduce nonadherence and thereby improve outcomes. This narrative review is based on a PubMed search (January 2000 - August 2022) for studies on LAI antipsychotics.

AREAS COVERED

Opportunities and challenges associated with LAIs are reviewed. Advantages, compared to oral antipsychotics (OAs), include improved adherence, reduced relapse and hospitalization risk, delayed and lower relapse risk after stopping treatment, and the ability to differentiate true treatment resistance from 'pseudo'-resistance. Additionally, LAIs are associated with lower all-cause mortality than OAs. LAIs are under-used in many services, partly reflecting negative attitudes, misconceptions, and lack of knowledge among clinicians, patients, and carers. Practical barriers to LAI use include acquisition costs and inadequate service structures to administer/monitor LAI treatment.

EXPERT OPINION

The education and engagement of clinicians, patients and caregivers can assist more informed decision-making regarding LAIs. Future research regarding LAIs should encompass multiple complementary designs, focus on functionality and recovery outcomes, and include groups at high risk of relapse, including those with comorbid substance use disorders and early in the course of schizophrenia.

A qualitative process evaluation of social recovery therapy for enhancement of social recovery in first-episode psychosis (SUPEREDEN3)

BACKGROUND

Many individuals with first-episode psychosis experience severe and persistent social disability despite receiving specialist early intervention. The SUPEREDEN3 trial assessed whether augmenting early intervention in psychosis services with Social Recovery Therapy (SRT) would lead to better social recovery.

AIMS

A qualitative process evaluation was conducted to explore implementation and mechanisms of SRT impact from the perspective of SUPEREDEN3 participants.

METHOD

A subsample of SUPEREDEN3 trial participants (n = 19) took part in semi-structured interviews, which were transcribed verbatim and analysed thematically. Trial participants were early intervention service users aged 16-35 years with severe and persistent social disability. Both SRT plus early intervention and early intervention alone arm participants were interviewed to facilitate better understanding of the context in which SRT was delivered and to aid identification of mechanisms specific to SRT.

RESULTS

The six themes identified were used to generate an explanatory model of SRT's enhancement of social recovery. Participant experiences highlight the importance of the therapist cultivating increased self-understanding and assertively encouraging clients to face feared situations in a way that is perceived as supportive, while managing ongoing symptoms. The sense of achievement generated by reaching targets linked to personally meaningful goals promotes increased self-agency, and generates hope and optimism.

CONCLUSIONS

The findings suggest potentially important processes through which social recovery was enhanced in this trial, which will be valuable in ensuring the benefits observed can be replicated. Participant accounts provide hope that, with the right support, even clients who have persistent symptoms and the most severe disability can make a good social recovery.

The Lived Experiences of Family Members and Carers of People with Psychosis: A Bottom-Up Review Co-Written by Experts by Experience and Academics

Informal caregivers of individuals affected by psychotic disorder can play a key role in the recovery process. However, little research has been conducted on the lived experiences of carers and family members. We conducted a bottom-up (from lived experience to theory) review of first-person accounts, co-written between academics and experts by experience, to identify key experiential themes. First-person accounts of carers, relatives, and individuals with psychosis were screened and discussed in collaborative workshops involving individuals with lived experiences of psychosis, family members, and carers, representing various organizations. The lived experiences of family members and carers were characterized by experiential themes related to dealing with the unexpected news, the search for a reason behind the disorder, living with difficult and negative emotions, dealing with loss, feeling lost in fragmented healthcare systems, feeling invisible and wanting to be active partners in care, struggling to communicate with the affected person, fighting stigma and isolation, dealing with an uncertain future, and learning from one's mistakes and building resilience and hope. Our findings bring forth the voices of relatives and informal carers of people with psychosis, by highlighting some of the common themes of their lived experiences from the time of the initial diagnosis and throughout the different clinical stages of the disorder. Informal carers are key stakeholders who can play a strategic role, and their contributions in the recovery process merit recognition and active support by mental health professionals.

Neuroimaging in schizophrenia: an overview of findings and their implications for synaptic changes

Over the last five decades, a large body of evidence has accrued for structural and metabolic brain alterations in schizophrenia. Here we provide an overview of these findings, focusing on measures that have traditionally been thought to reflect synaptic spine density or synaptic activity and that are relevant for understanding if there is lower synaptic density in the disorder. We conducted literature searches to identify meta-analyses or other relevant studies in patients with chronic or first-episode schizophrenia, or in people at high genetic or clinical risk for psychosis. We identified 18 meta-analyses including over 50,000 subjects in total, covering: structural MRI measures of gyrification index, grey matter volume, grey matter density and cortical thickness, neurite orientation dispersion and density imaging, PET imaging of regional glucose metabolism and magnetic resonance spectroscopy measures of N-acetylaspartate. We also review preclinical evidence on the relationship between ex vivo synaptic measures and structural MRI imaging, and PET imaging of synaptic protein 2A (SV2A). These studies show that schizophrenia is associated with lower grey matter volumes and cortical thickness, accelerated grey matter loss over time, abnormal gyrification patterns, and lower regional SV2A levels and metabolic markers in comparison to controls (effect sizes from ~ -0.11 to -1.0). Key regions affected include frontal, anterior cingulate and temporal cortices and the hippocampi. We identify several limitations for the interpretation of these findings in terms of understanding synaptic alterations. Nevertheless, taken with post-mortem findings, they suggest that schizophrenia is associated with lower synaptic density in some brain regions. However, there are several gaps in evidence, in particular whether SV2A findings generalise to other cohorts.

Effectiveness of Clozapine on Employment Outcomes in Treatment-Resistant Schizophrenia: A Retrospective Bidirectional Mirror-Image Study

Purpose

Clozapine is more effective than other antipsychotics and is the only antipsychotic approved for treatment-resistant schizophrenia. The objective of this study is to reveal the effect of clozapine on employment using a bidirectional mirror-image model.

Patients and Methods

This design was a retrospective observational study that investigated the employment status of patients with treatment-resistant schizophrenia based on medical records. The bidirectional mirror-image model consisted of 1) switching from other antipsychotics to clozapine and 2) switching from clozapine to other antipsychotics. The observation period was 1 year for each pre- and post-clozapine initiation and discontinuation.

Results

We included 36 patients in the bidirectional mirror-image model. The regular employment plus employment support rate was significantly higher in the clozapine phase than in the other antipsychotic phase in the bidirectional mirror-image model (30.6% vs 11.1%, P = 0.039). The days of regular employment plus employment support were also significantly longer in the clozapine phase (61.3 ± 106.2 vs 24.7 ± 82.7 days, P = 0.032). As per the unidirectional mirror-image model, switching to clozapine resulted in significantly higher regular employment plus employment support rates in the clozapine phase than those in the other antipsychotic phase (33.3% vs 10.0%, P = 0.039). Switching from clozapine to other antipsychotics did not exhibit significant differences in any outcomes.

Conclusion

The results suggest that clozapine is superior to other antipsychotics with respect to achieving employment in patients with treatment-resistant schizophrenia. However, biases specific to the mirror-image model need to be considered.

Neuropsychological functioning and suicidal behaviours in patients with first-episode psychosis: A systematic review

INTRODUCTION

Suicidal behaviour is particularly frequent in patients with psychosis. Therefore, prevention is a key objective of mental health policies. The aim of the current work is to systematically review the association between neurocognitive functioning and suicidal behaviour in patients with first-episode psychosis (FEP).

MATERIAL AND METHODS

Of the 3051 studies reviewed, only 7 met the inclusion criteria. Documents in English from their earliest date of coverage until January 2022 were searched for in the following databases: PubMed, Science Direct, Web of Science, Cochrane Library, PsycINFO (ProQuest), and Springerlink. We used the PICO strategy to collect and categorize the data from each selected manuscript.

RESULTS

Overall, the results showed that the risk of suicidal behaviour is higher for FEP patients in the presence of a number of factors: poorer general neuropsychological functioning (except for working memory), poorer social cognition, more depressive symptoms, longer duration of untreated psychosis, higher awareness of the illness, poorer premorbid adjustment, and more frequent cannabis use.

DISCUSSION

Comprehensive general neuropsychology and assessment of social cognition, together with routine clinical record keeping, may help to identify FEP patients at a greater risk of attempting suicide.

Descriptive outcomes for a cohort of high-frequency psychiatric service users in the Western Cape, South Africa after 10 years

Background: Assertive community treatment (ACT) is an intervention implemented to manage the effects of deinstitutionalisation. South African studies have reported decreased admissions at 12 and 36 months when a modified ACT intervention is compared with standard care. However, costs associated with the intervention have raised the question of its feasibility in developing countries.Aim: This study aimed to describe the long-term demographic and clinical outcomes of a group of psychiatric high-frequency users (HFUs) included in the first South African ACT study.Setting: Stikland Psychiatric Hospital, Cape Town, South Africa.Methods: Data from 55 HFUs participating in the first South African ACT trial, including both the intervention and control groups, were retrospectively reviewed 10 years after the patients’ inclusion.Results: Of the 55 HFUs initially included, nine remained in the formal ACT programme whilst 16 received standard care over the full 10 years. Five patients died and two were admitted to long-term wards. The mean number of admissions was 3.73 and the mean number of admission days was 261.11 over the 10 years. Twelve patients were never re-admitted; of these, nine came from the original study intervention group.Conclusions: This was the first study looking at the long-term outcomes of a group of psychiatric HFUs in an under-resourced setting receiving either a modified ACT intervention or standard outpatient care. Reflecting broadly on the group, there were a larger number of patients in the original ACT group who had no re-admissions and a comparatively higher utilisation of available services during the 10-year follow-up period.

Study protocol for the development and internal validation of Schizophrenia Prediction of Resistance to Treatment (SPIRIT): a clinical tool for predicting risk of treatment resistance to antipsychotics in first-episode schizophrenia

INTRODUCTION

Treatment-resistant schizophrenia (TRS) is associated with significant impairment of functioning and high treatment costs. Identification of patients at high risk of TRS at the time of their initial diagnosis may significantly improve clinical outcomes and minimise social and functional disability. We aim to develop a prognostic model for predicting the risk of developing TRS in patients with first-episode schizophrenia and to examine its potential utility and acceptability as a clinical decision tool.

METHODS AND ANALYSIS

We will use two well-characterised longitudinal UK-based first-episode psychosis cohorts: Aetiology and Ethnicity in Schizophrenia and Other Psychoses and Genetics and Psychosis for which data have been collected on sociodemographic and clinical characteristics. We will identify candidate predictors for the model based on current literature and stakeholder consultation. Model development will use all data, with the number of candidate predictors restricted according to available sample size and event rate. A model for predicting risk of TRS will be developed based on penalised regression, with missing data handled using multiple imputation. Internal validation will be undertaken via bootstrapping, obtaining optimism-adjusted estimates of the model's performance. The clinical utility of the model in terms of clinically relevant risk thresholds will be evaluated using net benefit and decision curves (comparative to competing strategies). Consultation with patients and clinical stakeholders will determine potential thresholds of risk for treatment decision-making. The acceptability of embedding the model as a clinical tool will be explored using qualitative focus groups with up to 20 clinicians in total from early intervention services. Clinicians will be recruited from services in Stafford and London with the focus groups being held via an online platform.

ETHICS AND DISSEMINATION

The development of the prognostic model will be based on anonymised data from existing cohorts, for which ethical approval is in place. Ethical approval has been obtained from Keele University for the qualitative focus groups within early intervention in psychosis services (ref: MH-210174). Suitable processes are in place to obtain informed consent for National Health Service staff taking part in interviews or focus groups. A study information sheet with cover letter and consent form have been prepared and approved by the local Research Ethics Committee. Findings will be shared through peer-reviewed publications, conference presentations and social media. A lay summary will be published on collaborator websites.

Peer supported Open Dialogue in the National Health Service: implementing and evaluating a new approach to Mental Health Care

BACKGROUND

Open Dialogue is an internationally developing approach to mental health care based on collaboration between an individual and their family and social network. Our quest for better approaches to Mental Health Care with improved carer and service user experience led us to develop and test a model of Peer Supported Open Dialogue (POD). There is no research currently looking at the implementation and effectiveness of a standalone POD team in the NHS so we evaluate its implementation, clinical outcomes and value to service users and their families.

METHOD

A before-after design was used. 50 service users treated by the POD Team were recruited and participants from their family and wider social network. Service user self report questionnaires covering wellbeing, functioning, satisfaction were collected and one carer self report measure; at baseline, three and six months. A clinician reported measure was collected at baseline and six months. Clinicians perceptions of practice were collected following network meetings.

RESULTS

50 service users treated were recruited with a mean age of 35 years with slightly more males than females. Service users reported signficant improvements in wellbeing and functioning. There was a marked increase in perceived support by carers. Over half the meetings were attended by carers. The Community Mental Health Survey showed high satisfaction rates for service users including carer involvement.

CONCLUSIONS

The study indicated it was possible to transform to deliver a clinically effective POD service in the NHS. This innovative approach provided continuity of care within the social network, with improved carer support and significant improvements in clinical outcomes and their experiences.

Psychosis REACH: Effects of a Brief CBT-Informed Training for Family and Caregivers of Individuals With Psychosis

OBJECTIVE

Psychosis Recovery by Enabling Adult Carers at Home (Psychosis REACH) is a training for families of individuals with psychosis that consists of recovery-oriented psychosis psychoeducation, caregiver self-care, and skills training informed by cognitive-behavioral therapy for psychosis (CBTp). The authors assessed the effects of a 1-day and a 4-day training on the natural supports (i.e., family and other caregivers) of individuals with psychotic disorders.

METHODS

Attendees of a 1-day (N=168) and a 4-day (N=29) Psychosis REACH training were surveyed at three timepoints: pretraining, posttraining, and 4-month follow-up. Longitudinal changes across the full sample were evaluated by paired-sample t tests or a one-way repeated-measures analysis of variance (ANOVA). Two-way mixed ANOVAs were conducted with training condition, time, and the training condition × time interactions entered into the model.

RESULTS

Reductions were noted in self-perceived depression, anxiety, negative aspects of the caregiving experience, and expressed emotion. Trainees also showed more prosocial attitudes toward psychosis immediately and at 4 months after the training.

CONCLUSIONS

This evaluation of the launch of Psychosis REACH in the United States suggests that the training can improve the mental health, attitudinal, and relational outcomes of family and caregivers of individuals with psychosis. Given the dearth of CBTp and family interventions for psychosis in mental health services in the United States, short-term, intensive training that supplements clinical services has intuitive appeal as a means of surmounting the barriers that have plagued family interventions.

Overlap and Mutual Distinctions Between Clinical Recovery and Personal Recovery in People With Schizophrenia in a One-Year Study

Recovery is a multidimensional construct that can be defined either from a clinical perspective or from a consumer-focused one, as a self-broadening process aimed at living a meaningful life beyond mental illness. We aimed to longitudinally examine the overlap and mutual distinctions between clinical and personal recovery. Of 1239 people with schizophrenia consecutively recruited from the FondaMental Advanced Centers of Expertise for SZ network, the 507 present at one-year did not differ from those lost to follow-up. Clinical recovery was defined as the combination of clinical remission and functional remission. Personal recovery was defined as being in the rebuilding or in the growth stage of the Stages of Recovery Instrument (STORI). Full recovery was defined as the combination of clinical recovery and personal recovery. First, we examined the factors at baseline associated with each aspect of recovery. Then, we conducted multivariable models on the correlates of stable clinical recovery, stable personal recovery, and stable full recovery after one year. At baseline, clinical recovery and personal recovery were characterized by distinct patterns of outcome (i.e. better objective outcomes but no difference in subjective outcomes for clinical recovery, the opposite pattern for personal recovery, and better overall outcomes for full recovery). We found that clinical recovery and personal recovery predicted each other over time (baseline personal recovery for stable clinical recovery at one year; P = .026, OR = 4.94 [1.30-23.0]; baseline clinical recovery for stable personal recovery at one year; P = .016, OR = 3.64 [1.31-11.2]). In short, given the interaction but also the degree of difference between clinical recovery and personal recovery, psychosocial treatment should target, beyond clinical recovery, subjective aspects such as personal recovery and depression to reach full recovery.

Incidence and method of suicide mortality in patients with schizophrenia: a Nationwide Cohort Study

PURPOSE

Suicide is a leading cause of death in patients with schizophrenia. This nationwide cohort study investigated the incidence of each suicide method in patients with schizophrenia compared with the general population.

METHODS

In total, records of 174,039 patients with schizophrenia were obtained from the National Health Insurance Research Database in Taiwan from 2001 to 2016. This schizophrenia cohort was linked with the national mortality database, and 26,926 patients died during this follow-up period. Of the deceased, 3033 had died by suicide. Univariate Cox regression was used to estimate the demographic variables associated with suicide. We estimated the difference in the proportion of each suicide method used in patients with schizophrenia compared with the general population. The incidence and standardized mortality ratio (SMR) of each suicide method were calculated and stratified based on sex.

RESULTS

Patients aged 25-34 years exhibited the highest suicide risk. Compared with the general population, patients with schizophrenia were more likely to commit suicide by jumping and drowning and less likely to use charcoal-burning and hanging. Women showed a higher incidence of suicide by drowning and jumping than did men. Comorbidity with substance use disorders (SUDs) was associated with a high suicide SMR (26.9, 95% confidence interval [CI] = 23.4-28.9), particularly for suicide by jumping (61.2, 95% CI = 48.3-76.3).

CONCLUSIONS

Patients with schizophrenia had higher suicide rates for all methods than did the general population. Suicide method differed based on sex. Patients with SUDs exhibit a high SMR for each suicide method and warrant intensive clinical attention.

Developing a Sound Body: Open Trial Results of a Group Healthy Lifestyle Intervention for Young Adults with Psychosis

The mortality disparity for persons with schizophrenia spectrum disorders (SSDs) due to cardiovascular disease is a devastating problem. Many risk factors are present in young adults with psychosis that may be ameliorated with lifestyle interventions. Sixteen participants with SSDs enrolled in an 11-week open trial of a novel lifestyle intervention comprised of group high intensity interval training exercise and health and wellness education. The aims were to evaluate (1) feasibility and (2) impact on sedentary behavior, physical activity, nutritional knowledge, physiological outcomes, and psychological well-being at end of intervention and 11-week follow-up. Attendance rates were 70% or higher for both intervention components and participants reported increased learning about healthy eating and exercise habits. Moderate to large effect sizes were observed for physical activity and sedentary behavior with sustained improvements in sedentary behavior at follow-up. Meaningful changes were not observed in other domains.

Overview and Use of Tools for Selecting Modelling Techniques in Health Economic Studies

The availability and use of tools to guide the choice of modelling technique are not well understood. Our study aims to review existing tools and explore the use of those tools in health economic models. Two reviews and one case study were conducted. Review 1 aimed to identify tools based on expert opinion and citation searching and explore the value of the tools for health economic models. Review 2, based on citation searching, aimed to describe how those tools have been used in health economic models. Both reviews were conducted using Web of Science and Scopus. Two independent reviewers selected studies for inclusion. A case study, focused on economic evaluations of antipsychotic medication in schizophrenia, was conducted to compare the modelling techniques used by existing models with modelling techniques recommended by identified tools. Seven tools were identified, of which the revised Brennan's toolkit, was assessed to be the most appropriate for health economic models. The seven tools were cited 126 times in publications reporting health economic models. Only 17 of these (13.5%) reported that they used the tool(s) to guide the choice of modelling technique. Application of these tools suggested discrete event simulation is most appropriate for modelling antipsychotic medication in schizophrenia, but discrete event simulation was only used by 17% of existing models. There is considerable inconsistency between the modelling techniques used by existing models and modelling techniques recommended by tools. It is recommended that for future modelling studies the choice of modelling technique should be justified, this can be achieved by the application of model selection tools, such as the revised Brennan's toolkit. Future research is required to explore the barriers to using model selection tools in health economic models and to update existing tools and make them easier to use.

First episode psychosis: A comparison of caregiving appraisals in parents caring for the same child

BACKGROUND

The first onset of psychosis can be a traumatic event for diagnosed individuals but can also impact negatively on their families. Little is known about how parents of the same child make sense of the illness. In mothers and fathers caring for the same child with early psychosis, the current study assessed their similarities and differences in key areas of their caregiving role.

METHODS

Using a cross-sectional design, parental pairs caring for the same child treated within an early intervention in psychosis service, completed self-report measures on their caregiving experiences, illness beliefs, coping styles and affect.

RESULTS

Data from 44 mothers and fathers were analysed. Analyses confirmed that parents reported similar levels of emotional dysfunction and conceptualized the illness in broadly similar ways with regard to what they understood the illness to be, their emotional reactions to the illness, perceived illness consequences and beliefs about treatment. Significant differences were identified in their beliefs about the timeline of the illness and reported approaches to coping.

CONCLUSIONS

With exception of beliefs about illness timeline and an expressed preference for use of emotion-based coping, parent caregivers of the same child in early psychosis services are likely to report similar illness beliefs and caregiving reactions. Efforts to ensure staff awareness of the potential areas of divergence in parental caregiving appraisals and exploring the implications of the divergence for the caregiving relationship and patient outcomes are indicated.

Schizophrenia outcomes in the 21st century: A systematic review

OBJECTIVE

We report a review of outcomes in schizophrenia in the twenty-first century, replicating and extending work undertaken by the late Richard Warner in his seminal book, "Recovery from Schizophrenia: Psychiatry and Political Economy" (1985;2004).

METHOD

Warner's methods were followed as closely as possible. Only observational/naturalistic studies were included. Six scientific databases were searched from 2000 to 2020. 6,640 records were retrieved. 47 met inclusion criteria.

RESULTS

Overall, complete recovery is higher in this study than in Warner's (37.75% cf 20.4%), especially for first episode psychosis (FEP) (57.1% cf 20.7%). Clinical recovery, annualized remission rate (ARR), and employment outcomes were significantly superior for first episode psychosis compared with multiple episode psychosis (MEP). ARR shows a trend toward reduction over time, from 2.2 before the financial crash of 2008 to 1.6 after (t = 1.85 df 40 p = .07). The decline is statistically significant for the MEP group (t = 2.32 df18 p = .03). There were no differences in outcome by region, sample characteristics, outcome measures used, or quality of studies. Heterogeneity of clinical outcome measures across the literature makes evidence synthesis difficult. Weak and inconsistent reporting of functional and employment outcomes mean that findings lack meaning with respect to lived experience.

CONCLUSION

Future research strategies should aim to reduce heterogeneity in clinical outcome measures and to increase the emphasis on capture and reporting of more sophisticated measures of social and functional outcome. Outcome domains should be disaggregated rather than conflated into unitary recovery constructs.

Carer subjective burden after first-episode psychosis: Types and predictors. A multilevel statistical approach

BACKGROUND

Carer burden at first-episode psychosis is common and adds to the multiple other psychiatric and psychological problems that beset new carers; yet, knowledge of the factors that predict carer burden is limited.

AIM

This study sought to investigate the types and predictors of carer burden at first-episode psychosis in the largest, most ethnically diverse and comprehensively characterised sample to date.

METHOD

This study involved a cross-sectional survey of carers of people with first-episode psychosis presenting to Harrow and Hillingdon Early Intervention in Psychosis service between 2011 and 2017. Carers completed self-report measures assessing their illness beliefs, coping styles and caregiving experiences (i.e. burden). Thirty carer and patient sociodemographic and clinical factors were also collected. Mixed effects linear regression modelling was conducted to account for clustering of carers by patient, with carer burden (and its 8 subtypes) investigated as dependent variables.

RESULTS

The sample included data on 254 carers (aged 18-74 years) and 198 patients (aged 14-36 years). Regression modelling identified 35 significant predictors of carer burden and its subtypes at first-episode psychosis. Higher total burden was independently predicted by perceiving greater negative consequences of the illness for the patient (B = .014, p < .001, 95% CI: [.010-.018]) and the carer (B = .008, p = .002, 95% CI: [.003-.013]), and engaging in avoidant-focussed coping (B = .010, p = .006, 95% CI: [.003-.016]). Lower burden was independently predicted by patients being in a relationship (B = -.075, p = .047, 95% CI: [-.149 to -.001]). Predictors of the eight burden subtypes (difficult behaviours, negative symptoms, stigma, problems with services, effects on family, dependency, loss and need to backup) are also included in the article.

CONCLUSION

Findings can be used to inform the identification of carers 'at-risk' of experiencing burden and highlight potential targets for theraputic intervention to lower carer buden.

Violence by Persons with Serious Mental Illness Toward Family Caregivers and Other Relatives: A Review

Persons living with serious mental illness (SMI) are at a modestly increased risk of committing violence and are disproportionately likely to target family members when they do commit violence. In this article, we review available evidence regarding violence by persons with SMI toward family members, many of whom are caregivers. Evidence suggests that a sizable minority of family members with high levels of contact with persons with SMI have experienced violence, with most studies finding rates of past year victimization to be 20% or higher. Notable risk factors for family violence pertaining specifically to persons with SMI include substance use, nonadherence to medications and mental health treatment, history of violent behavior, and recent victimization. Notable risk factors pertaining specifically to the relationships between persons with SMI and family members include persons with SMI relying on family members for tangible and instrumental support, family members setting limits, and the presence of criticism, hostility, and verbal aggression. As described in qualitative studies, family members often perceive violence to be connected to psychiatric symptoms and inadequate treatment experiences. We argue that promising strategies for preventing violence by persons with SMI toward family members include (1) better engaging persons with SMI in treatment, through offering more recovery-oriented care, (2) strengthening support services for persons with SMI that could reduce reliance on family members, and (3) supporting the capabilities of family members to prevent and manage family conflict. The available interventions that may be effective in this context include McFarlane's Multifamily Group intervention and the Family-to-Family educational program.

Specialised early intervention teams (extended time) for recent-onset psychosis

BACKGROUND

Psychosis is an illness characterised by the presence of hallucinations and delusions that can cause distress or a marked change in an individual's behaviour (e.g. social withdrawal, flat or blunted effect). A first episode of psychosis (FEP) is the first time someone experiences these symptoms that can occur at any age, but the condition is most common in late adolescence and early adulthood. This review is concerned with FEP and the early stages of a psychosis, referred to throughout this review as 'recent-onset psychosis.' Specialised early intervention (SEI) teams are community mental health teams that specifically treat people who are experiencing, or have experienced, a recent-onset psychosis. SEI teams provide a range of treatments including medication, psychotherapy, psychoeducation, educational and employment support, augmented by assertive contact with the service user and small caseloads. Treatment is time limited, usually offered for two to three years, after which service users are either discharged to primary care or transferred to a standard adult community mental health team. Evidence suggests that once SEI treatment ends, improvements may not be sustained, bringing uncertainty about the optimal duration of SEI to ensure the best long-term outcomes. Extending SEI has been proposed as a way of providing continued intensive treatment and continuity of care, of usually up to five years, in order to a) sustain the positive initial outcomes of SEI; and b) improve the long-term trajectory of the illness.

OBJECTIVES

To compare extended SEI teams with treatment as usual (TAU) for people with recent-onset psychosis. To compare extended SEI teams with standard SEI teams followed by TAU (standard SEI + TAU) for people with recent-onset psychosis.

SEARCH METHODS

On 3 October 2018 and 22 October 2019, we searched Cochrane Schizophrenia's study-based register of trials, including registries of clinical trials.

SELECTION CRITERIA

We selected all randomised controlled trials (RCTs) comparing extended SEI with TAU for people with recent-onset psychosis and all RCTs comparing extended SEI with standard SEI + TAU for people with recent-onset psychosis. We entered trials meeting these criteria and reporting usable data as included studies.

DATA COLLECTION AND ANALYSIS

We independently inspected citations, selected studies, extracted data and appraised study quality. For binary outcomes we calculated the risk ratios (RRs) and their 95% confidence intervals (CIs). For continuous outcomes we calculated the mean difference (MD) and their 95% CIs, or if assessment measures differed for the same construct, we calculated the standardised mean difference (SMD) with 95% CIs. We assessed risk of bias for included studies and created a 'Summary of findings' table using the GRADE approach.

MAIN RESULTS

We included three RCTs, with a total 780 participants, aged 16 to 35 years. All participants met the criteria for schizophrenia spectrum disorders or affective psychoses. No trials compared extended SEI with TAU. All three trials randomly allocated people approximately two years into standard SEI to either extended SEI or standard SEI + TAU. The certainty of evidence for outcomes varied from low to very low. Our primary outcomes were recovery and disengagement from mental health services. No trials reported on recovery, and we used remission as a proxy. Three trials reported on remission, with the point estimate suggesting a 13% increase in remission in favour of extended SEI, but this included wide confidence intervals (CIs) and a very uncertain estimate of no benefit (RR 1.13, 95% CI 0.97 to 1.31; 3 trials, 780 participants; very low-certainty evidence). Two trials provided data on disengagement from services with evidence that extended SEI care may result in fewer disengagements from mental health treatment (15%) in comparison to standard SEI + TAU (34%) (RR 0.45, 95% CI 0.27 to 0.75; 2 trials, 380 participants; low-certainty evidence). There may be no evidence of a difference in rates of psychiatric hospital admission (RR 1.55, 95% CI 0.68 to 3.52; 1 trial, 160 participants; low-certainty evidence), or the number of days spent in a psychiatric hospital (MD -2.70, 95% CI -8.30 to 2.90; 1 trial, 400 participants; low-certainty evidence). One trial found uncertain evidence regarding lower global psychotic symptoms in extended SEI in comparison to standard SEI + TAU (MD -1.90, 95% CI -3.28 to -0.52; 1 trial, 156 participants; very low-certainty evidence). It was uncertain whether the use of extended SEI over standard SEI + TAU resulted in fewer deaths due to all-cause mortality, as so few deaths were recorded in trials (RR 0.38, 95% CI 0.09 to 1.64; 3 trials, 780 participants; low-certainty evidence). Very uncertain evidence suggests that using extended SEI instead of standard SEI + TAU may not improve global functioning (SMD 0.23, 95% CI -0.29 to 0.76; 2 trials, 560 participants; very low-certainty evidence). There was low risk of bias in all three trials for random sequence generation, allocation concealment and other biases. All three trials had high risk of bias for blinding of participants and personnel due to the nature of the intervention. For the risk of bias for blinding of outcome assessments and incomplete outcome data there was at least one trial with high or unclear risk of bias.

AUTHORS' CONCLUSIONS

There may be preliminary evidence of benefit from extending SEI team care for treating people experiencing psychosis, with fewer people disengaging from mental health services. Evidence regarding other outcomes was uncertain. The certainty of evidence for the measured outcomes was low or very low. Further, suitably powered studies that use a consistent approach to outcome selection are needed, but with only one further ongoing trial, there is unlikely to be any definitive conclusion for the effectiveness of extended SEI for at least the next few years.

Specialised early intervention teams for recent-onset psychosis

BACKGROUND

Psychosis is an illness characterised by the presence of hallucinations and delusions that can cause distress or a marked change in an individual's behaviour (e.g. social withdrawal, flat or blunted effect). A first episode of psychosis (FEP) is the first time someone experiences these symptoms that can occur at any age, but the condition is most common in late adolescence and early adulthood. This review is concerned with first episode psychosis (FEP) and the early stages of a psychosis, referred to throughout this review as 'recent-onset psychosis.' Specialised early intervention (SEI) teams are community mental health teams that specifically treat people who are experiencing, or have experienced a recent-onset psychosis. The purpose of SEI teams is to intensively treat people with psychosis early in the course of the illness with the goal of increasing the likelihood of recovery and reducing the need for longer-term mental health treatment. SEI teams provide a range of treatments including medication, psychotherapy, psychoeducation, and occupational, educational and employment support, augmented by assertive contact with the service user and small caseloads. Treatment is time limited, usually offered for two to three years, after which service users are either discharged to primary care or transferred to a standard adult community mental health team. A previous Cochrane Review of SEI found preliminary evidence that SEI may be superior to standard community mental health care (described as 'treatment as usual (TAU)' in this review) but these recommendations were based on data from only one trial. This review updates the evidence for the use of SEI services.

OBJECTIVES

To compare specialised early intervention (SEI) teams to treatment as usual (TAU) for people with recent-onset psychosis.

SEARCH METHODS

On 3 October 2018 and 22 October 2019, we searched Cochrane Schizophrenia's study-based register of trials, including registries of clinical trials.

SELECTION CRITERIA

We selected all randomised controlled trials (RCTs) comparing SEI with TAU for people with recent-onset psychosis. We entered trials meeting these criteria and reporting useable data as included studies.

DATA COLLECTION AND ANALYSIS

We independently inspected citations, selected studies, extracted data and appraised study quality. For binary outcomes we calculated the risk ratios (RRs) and their 95% confidence intervals (CIs). For continuous outcomes we calculated the mean difference (MD) and their 95% CIs, or if assessment measures differed for the same construct, we calculated the standardised mean difference (SMD) with 95% CIs. We assessed risk of bias for included studies and created a 'Summary of findings' table using the GRADE approach.

MAIN RESULTS

We included three RCTs and one cluster-RCT with a total of 1145 participants. The mean age in the trials was between 23.1 years (RAISE) and 26.6 years (OPUS). The included participants were 405 females (35.4%) and 740 males (64.6%). All trials took place in community mental healthcare settings. Two trials reported on recovery from psychosis at the end of treatment, with evidence that SEI team care may result in more participants in recovery than TAU at the end of treatment (73% versus 52%; RR 1.41, 95% CI 1.01 to 1.97; 2 studies, 194 participants; low-certainty evidence). Three trials provided data on disengagement from services at the end of treatment, with fewer participants probably being disengaged from mental health services in SEI (8%) in comparison to TAU (15%) (RR 0.50, 95% CI 0.31 to 0.79; 3 studies, 630 participants; moderate-certainty evidence). There was low-certainty evidence that SEI may result in fewer admissions to psychiatric hospital than TAU at the end of treatment (52% versus 57%; RR 0.91, 95% CI 0.82 to 1.00; 4 studies, 1145 participants) and low-certainty evidence that SEI may result in fewer psychiatric hospital days (MD -27.00 days, 95% CI -53.68 to -0.32; 1 study, 547 participants). Two trials reported on general psychotic symptoms at the end of treatment, with no evidence of a difference between SEI and TAU, although this evidence is very uncertain (SMD -0.41, 95% CI -4.58 to 3.75; 2 studies, 304 participants; very low-certainty evidence). A different pattern was observed in assessment of general functioning with an end of trial difference that may favour SEI (SMD 0.37, 95% CI 0.07 to 0.66; 2 studies, 467 participants; low-certainty evidence). It was uncertain whether the use of SEI resulted in fewer deaths due to all-cause mortality at end of treatment (RR 0.21, 95% CI 0.04 to 1.20; 3 studies, 741 participants; low-certainty evidence). There was low risk of bias for random sequence generation and allocation concealment in three of the four included trials; the remaining trial had unclear risk of bias. Due to the nature of the intervention, we considered all trials at high risk of bias for blinding of participants and personnel. Two trials had low risk of bias and two trials had high risk of bias for blinding of outcomes assessments. Three trials had low risk of bias for incomplete outcome data, while one trial had high risk of bias. Two trials had low risk of bias, one trial had high risk of bias, and one had unclear risk of bias for selective reporting.

AUTHORS' CONCLUSIONS

There is evidence that SEI may provide benefits to service users during treatment compared to TAU. These benefits probably include fewer disengagements from mental health services (moderate-certainty evidence), and may include small reductions in psychiatric hospitalisation (low-certainty evidence), and a small increase in global functioning (low-certainty evidence) and increased service satisfaction (moderate-certainty evidence). The evidence regarding the effect of SEI over TAU after treatment has ended is uncertain. Further evidence investigating the longer-term outcomes of SEI is needed. Furthermore, all the eligible trials included in this review were conducted in high-income countries, and it is unclear whether these findings would translate to low- and middle-income countries, where both the intervention and the comparison conditions may be different.

Prevalence of treatment resistance and clozapine use in early intervention services

BACKGROUND

Treatment resistance causes significant burden in psychosis. Clozapine is the only evidence-based pharmacologic intervention available for people with treatment-resistant schizophrenia; current guidelines recommend commencement after two unsuccessful trials of standard antipsychotics.

AIMS

This paper aims to explore the prevalence of treatment resistance and pathways to commencement of clozapine in UK early intervention in psychosis (EIP) services.

METHOD

Data were taken from the National Evaluation of the Development and Impact of Early Intervention Services study (N = 1027) and included demographics, medication history and psychosis symptoms measured by the Positive and Negative Syndrome Scale (PANSS) at baseline, 6 months and 12 months. Prescribing patterns and pathways to clozapine were examined. We adopted a strict criterion for treatment resistance, defined as persistent elevated positive symptoms (a PANSS positive score ≥16, equating to at least two items of at least moderate severity), across three time points.

RESULTS

A total of 143 (18.1%) participants met the definition of treatment resistance of having continuous positive symptoms over 12 months, despite treatment in EIP services. Sixty-one (7.7%) participants were treatment resistant and eligible for clozapine, having had two trials of standard antipsychotics; however, only 25 (2.4%) were prescribed clozapine over the 12-month study period. Treatment-resistant participants were more likely to be prescribed additional antipsychotic medication and polypharmacy, instead of clozapine.

CONCLUSIONS

Prevalent treatment resistance was observed in UK EIP services, but prescription of polypharmacy was much more common than clozapine. Significant delays in the commencement of clozapine may reflect a missed opportunity to promote recovery in this critical period.

Improving access to services for psychotic patients: does implementing a waiting time target make a difference

OBJECTIVE

In April 2015, the English National Health Service started implementing the first waiting time targets in mental health care. This study aims to investigate the effect of the 14-day waiting time target for early intervention in psychosis (EIP) services after the first six months of its implementation.

STUDY DESIGN

We analyse a cohort of first-episode psychosis patients from the English administrative Mental Health and Learning Disabilities Dataset 2011 to 2015. We compare patients being treated by EIP services (treatment) with those receiving care from standard community mental health services (control). We combine non-parametric matching with a difference-in-difference approach to account for observed and unobserved group differences. We analyse the probability of waiting below target and look at different percentiles of the waiting time distribution.

RESULTS

EIP patients had an 11.6-18.4 percentage point higher chance of waiting below target post-policy compared to standard care patients. However, post-policy trends at different percentiles of the waiting time distribution were not different between groups.

CONCLUSIONS

Mental health providers seem to respond to waiting time targets in a similar way as physical health providers. The increased proportion waiting below target did not, however, result in an overall improvement across the waiting time distribution.

The report of the joint WPA/CINP workgroup on the use and usefulness of antipsychotic medication in the treatment of schizophrenia

This is a report of a joint World Psychiatric Association/International College of Neuropsychopharmacology (WPA/CINP) workgroup concerning the risk/benefit ratio of antipsychotics in the treatment of schizophrenia. It utilized a selective but, within topic, comprehensive review of the literature, taking into consideration all the recently discussed arguments on the matter and avoiding taking sides when the results in the literature were equivocal. The workgroup's conclusions suggested that antipsychotics are efficacious both during the acute and the maintenance phase, and that the current data do not support the existence of a supersensitivity rebound psychosis. Long-term treated patients have better overall outcome and lower mortality than those not taking antipsychotics. Longer duration of untreated psychosis and relapses are modestly related to worse outcome. Loss of brain volume is evident already at first episode and concerns loss of neuropil volume rather than cell loss. Progression of volume loss probably happens in a subgroup of patients with worse prognosis. In humans, antipsychotic treatment neither causes nor worsens volume loss, while there are some data in favor for a protective effect. Schizophrenia manifests 2 to 3 times higher mortality vs the general population, and treatment with antipsychotics includes a number of dangers, including tardive dyskinesia and metabolic syndrome; however, antipsychotic treatment is related to lower mortality, including cardiovascular mortality. In conclusion, the literature strongly supports the use of antipsychotics both during the acute and the maintenance phase without suggesting that it is wise to discontinue antipsychotics after a certain period of time. Antipsychotic treatment improves long-term outcomes and lowers overall and specific-cause mortality.

Service users' and carers' experiences of engaging with early intervention services: A meta-synthesis review

AIM

The provision and implementation of early intervention for psychosis services (early intervention services [EIS]) has received increasing attention over recent years. Maximizing engagement with EIS is of clinical and economic importance, and exploring the experiences of those who access EIS is vital. Although research has been conducted exploring the experiences of engaging with EIS from both a service user and carer/family member point of view, these data have not been systematically collated to generate new understanding. The primary aim of this study is to review, critically appraise and synthesize qualitative findings relating to the experiences of service users and/or carers and family members engaging with EIS.

METHODS

Four databases were systematically searched. Studies were analysed using an inductive thematic analysis approach, within a critical realist epistemological framework. Studies were critically appraised using the critical appraisal skills programme tool.

RESULTS

Fourteen papers were identified for inclusion. Three main themes were identified: the importance of a personal relationship with an EIS staff member, the impact of this relationship and consideration of life after EIS. The importance of a strong relationship with EIS staff was the most prominent theme throughout the papers reviewed.

CONCLUSIONS

The quality of the therapeutic relationship with at least one EIS staff member was the single most important factor in determining whether the experience of accessing EIS was a positive or negative one. The majority of the studies reviewed were conducted in the United Kingdom or Australia. Therefore, more research across countries is needed to understand transferability of findings.

[Evidence-based treatment of acute psychotic episode and schizophrenia in children and adolescents]

Children and adolescents are a special group in the context of psychopharmacotherapy. Given the limited choice of registered antipsychotics permitted in childhood, caution should be exercised in the choice of medication. This literature review reviews the current evidence base for pharmacotherapy of acute psychotic episode and schizophrenia in children and adolescents. The results of major systematic reviews and meta-analyses are compared. Meta-analyses of pharmacotherapy studies of the first psychotic episode are considered separately. Antipsychotics of the first and second generation are comparable in effectiveness for children and adolescents with acute psychotic episode. Olanzapine demonstrates higher efficacy in reducing negative symptoms. Ziprasidone and asenapine are less effective in treating schizophrenia in children and adolescents than other antipsychotics. Compared to adults, children and adolescents are at higher risk of metabolic impairments when taking antipsychotics.

Trajectory and early predictors of apathy development in first-episode psychosis and healthy controls: a 10-year follow-up study

Apathy is prevalent in first-episode psychosis (FEP) and associated with reduced global functioning. Investigations of the trajectory of apathy and its early predictors are needed to develop new treatment interventions. We here measured the levels of apathy over the first 10 years of treatment in FEP and in healthy controls (HC). We recruited 198 HC and 198 FEP participants. We measured apathy with the Apathy Evaluation Scale, self-report version, psychotic symptoms with the Positive and Negative Syndrome Scale, depression with the Calgary Depression Scale for Schizophrenia, functioning with the Global Assessment of Functioning Scale, and also estimated the duration of untreated psychosis (DUP). The longitudinal development of apathy and its predictors were explored using linear mixed models analyses. Associations to functioning at 10 years were investigated using multiple hierarchical linear regression analyses. In HC, mean apathy levels were low and stable. In FEP, apathy levels decreased significantly during the first year of treatment, followed by long-term stability. High individual levels of apathy at baseline were associated with higher apathy levels during the follow-up. Long DUP and high baseline levels of depression predicted higher apathy levels at follow-ups. The effect of DUP was persistent, while the effect of baseline depression decreased over time. At 10 years, apathy was statistically significantly associated with reduced functioning. The early phase of the disorder may be critical to the development of apathy in FEP.

Jumping to conclusions at first onset of psychosis predicts longer admissions, more compulsory admissions and police involvement over the next 4 years: the GAP study

BACKGROUND

Jumping to conclusions (JTC), which is the proneness to require less information before forming beliefs or making a decision, has been related to formation and maintenance of delusions. Using data from the National Institute of Health Research Biomedical Research Centre Genetics and Psychosis (GAP) case-control study of first-episode psychosis (FEP), we set out to test whether the presence of JTC would predict poor clinical outcome at 4 years.

METHODS

One-hundred and twenty-three FEP patients were assessed with the Positive and Negative Syndrome Scale (PANSS), Global Assessment of Functioning (GAF) and the probabilistic reasoning 'Beads' Task at the time of recruitment. The sample was split into two groups based on the presence of JTC bias. Follow-up data over an average of 4 years were obtained concerning clinical course and outcomes (remission, intervention of police, use of involuntary treatment - the Mental Health Act (MHA) - and inpatient days).

RESULTS

FEP who presented JTC at baseline were more likely during the follow-up period to be detained under the MHA [adjusted OR 15.62, 95% confidence interval (CI) 2.92-83.54, p = 0.001], require intervention by the police (adjusted OR 14.95, 95% CI 2.68-83.34, p = 0.002) and have longer admissions (adjusted IRR = 5.03, 95% CI 1.91-13.24, p = 0.001). These associations were not accounted for by socio-demographic variables, IQ and symptom dimensions.

CONCLUSIONS

JTC in FEP is associated with poorer outcome as indicated and defined by more compulsion police intervention and longer periods of admission. Our findings raise the question of whether the implementation of specific interventions to reduce JTC, such as Metacognition Training, may be a useful addition in early psychosis intervention programmes.

The association between family dysfunction and admission to an acute mental health inpatient unit: a prospective study

OBJECTIVES

With the shift from deinstitutionalization to community care in mental health services, relatives of persons with severe and enduring mental illnesses have had to take over the role as primary caregivers. Disturbed family dynamics have been observed within families with an 'ill' member. Although schizophrenia and related mental illnesses are biologically based disorders, environmental stress (including stress within family relationships) plays a major role in the onset and maintenance of symptoms. With this study, we assume that family dynamics play a central role in the course of severe psychiatric illness and hypothesized that dysfunction within family systems is a prognostic indicator of hospitalization in the course of schizophrenia/bipolar and schizoaffective disorders.

METHODS

Prospective, observational cohort study evaluating family functioning of 121 patients (schizophrenia/bipolar and schizoaffective disorder) from community at baseline and followed-up over 12-month period after recruitment. Measurements included demographics, diagnosis, Family Assessment Device - General Functioning, Perceived Criticism Scale, Brief Psychiatric Rating Scale, Global Assessment of Functioning and Social Support Questionnaire-6.

RESULTS

Significant differences found between patients admitted and not admitted during the 12-month time period for age (p = 0.003), Brief Psychiatric Rating Scale (BPRS; p = 0.026), Family Assessment Device - General Functioning (FAD-GF; p = 0.007) and Social Support Questionnaire total satisfaction level (p = 0.042) at baseline. Bivariate analysis showed that those admitted into hospital were younger with a higher BPRS score, less social satisfaction and disturbed family dynamics. FAD-GF (p = 0.006) and age (p = 0.022) were significant independent predictors for admission.

CONCLUSION

This provides further evidence supporting importance of promoting better family functioning through modified family dynamics, integrating and involving family into the care of such patients.

Peer support and skills training through an eating club for people with psychotic disorders: A feasibility study

OBJECTIVE

The HospitalitY (HY) intervention is a novel recovery oriented intervention for people with psychotic disorders in which peer support and home-based skill training are combined in an eating club. A feasibility study was conducted to inform a subsequent randomised trial.

METHODS

This study evaluated three eating clubs consisting of nine participants and three nurses. Semi-structured interviews and pre- and post-intervention measures (18 weeks) of personal recovery, quality of life and functioning were used to evaluate the intervention. Participants received individual skills training, guided by self-identified goals, while organising a dinner at their home. During each dinner, participants engaged in peer support, led by a nurse.

RESULTS

In personal interviews participants reported positive effects on social support, loneliness, and self-esteem. Nurses reported that participants became more independent during the intervention. Participants were satisfied with the HY-intervention (attendance rate = 93%). All were able to organise a dinner for their peers with practical support from a nurse. Pre- and post -intervention measures did not show important improvements.

LIMITATIONS

Outcome measures were not sensitive to change, likely due to a short intervention period (5 months) and a limited number of participants (N = 9). Using Goal Attainment Scaling to evaluate personal goals turned out to be unfeasible.

CONCLUSIONS

The HY-intervention is feasible for participants with psychotic disorders. This study refined intervention and research design for the upcoming multicentre randomised controlled trial. We expect that the Experience Sampling Method will be more sensitive to changes in recovery outcomes than regular pre-post intervention measures.

Common Data Elements for National Institute of Mental Health-Funded Translational Early Psychosis Research

The National Institutes of Health has established the PhenX Toolkit as a web-based resource containing consensus measures freely available to the research community. The National Institute of Mental Health (NIMH) has introduced the Mental Health Research Core Collection as part of the PhenX Toolkit and recently convened the PhenX Early Psychosis Working Group to generate the PhenX Early Psychosis Specialty Collection. The Working Group consisted of two complementary panels for clinical and translational research. We review the process, deliberations, and products of the translational research panel. The Early Psychosis Specialty Collection rationale for measure selection as well as additional information and protocols for obtaining each measure are available on the PhenX website (https://www.phenxtoolkit.org). The NIMH strongly encourages investigators to use instruments from the PhenX Mental Health Research Collections in NIMH-funded studies and discourages use of alternative measures to collect similar data without justification. We also discuss some of the potential advances that can be achieved by collecting common data elements across large-scale longitudinal studies of early psychosis.

Antipsychotics: Mechanisms underlying clinical response and side-effects and novel treatment approaches based on pathophysiology

Antipsychotic drugs are central to the treatment of schizophrenia and other psychotic disorders but are ineffective for some patients and associated with side-effects and nonadherence in others. We review the in vitro, pre-clinical, clinical and molecular imaging evidence on the mode of action of antipsychotics and their side-effects. This identifies the key role of striatal dopamine D2 receptor blockade for clinical response, but also for endocrine and motor side-effects, indicating a therapeutic window for D2 blockade. We consider how partial D2/3 receptor agonists fit within this framework, and the role of off-target effects of antipsychotics, particularly at serotonergic, histaminergic, cholinergic, and adrenergic receptors for efficacy and side-effects such as weight gain, sedation and dysphoria. We review the neurobiology of schizophrenia relevant to the mode of action of antipsychotics, and for the identification of new treatment targets. This shows elevated striatal dopamine synthesis and release capacity in dorsal regions of the striatum underlies the positive symptoms of psychosis and suggests reduced dopamine release in cortical regions contributes to cognitive and negative symptoms. Current drugs act downstream of the major dopamine abnormalities in schizophrenia, and potentially worsen cortical dopamine function. We consider new approaches including targeting dopamine synthesis and storage, autoreceptors, and trace amine receptors, and the cannabinoid, muscarinic, GABAergic and glutamatergic regulation of dopamine neurons, as well as post-synaptic modulation through phosphodiesterase inhibitors. Finally, we consider treatments for cognitive and negative symptoms such dopamine agonists, nicotinic agents and AMPA modulators before discussing immunological approaches which may be disease modifying.

Rehabilitation and recovery for ethnic minority patients with severe mental illness

There is growing evidence to support recovery and rehabilitation services and interventions for people with severe mental illness (SMI). However, those from ethnic minority communities face inequitable outcomes and access to mental health services and poorer functional outcomes. This article reviews the evidence and discusses facilitators and barriers in the recovery journey of people with SMI from ethnic minority groups. Although there is limited evidence for specific interventions for ethnic minority patients, areas for future study and action are discussed.

Social inclusion and its interrelationships with social cognition and social functioning in first-episode psychosis

AIM

People with psychosis are at risk of social exclusion. Research is needed in this area due to the lack of direct measurement of social inclusion, which becomes salient in adolescence and is relevant to first-episode psychosis (FEP; the onset of which typically occurs during or shortly after adolescence). Social inclusion may be impacted by impaired social cognition and social functioning, which are related features observed in psychosis. The aim of this study was to explore interrelationship(s) between social cognition, social functioning and social inclusion in FEP while controlling for symptomatology (positive, negative and depressive symptoms) and demographic characteristics.

METHODS

A series of cross-sectional hierarchical multiple regressions were conducted to examine whether: social cognition (theory of mind, emotion recognition) predicted social functioning; social functioning predicted social inclusion, and whether social functioning mediated the relationship between social cognition and social inclusion in people aged 15 to 25 (M = 20.49, SD = 2.41) with FEP (N = 146). Age, sex, premorbid IQ, positive and negative psychotic symptoms and depression were control variables.

RESULTS

Poor facial emotion recognition (β = -.22, P < .05) and negative symptoms (β = -.45, P < .001) predicted lower social functioning. Role-specific social functioning (ie, current employment) predicted greater social inclusion (β = .17, P < .05). Higher depression symptomatology predicted lower social inclusion (β = -.43, P < .001). Social functioning did not mediate the relationship between social cognition and inclusion. Psychotic symptoms were unrelated to social inclusion.

CONCLUSIONS

Employment and depression may influence social inclusion somewhat independently of psychotic symptomatology in FEP. Inferences should be viewed with caution given this study did not involve longitudinal data.

Predictors and moderators of burden of care and emotional distress in first-episode psychosis caregivers: results from the GET UP pragmatic cluster randomised controlled trial

AIMS

First-episode psychosis (FEP) is a major life event and can have an adverse impact on the diagnosed individual and their families. The importance of intervening early and providing optimal treatments is widely acknowledged. In comparison to patient groups, literature is scarce on identifying treatment predictors and moderators of caregiver outcomes. This study aimed to identify pre-treatment characteristics predicting and/or moderating carer outcomes, based on data from a multi-element psychosocial intervention to FEP patients and carers (GET-UP PIANO trial).

METHODS

Carer demography, type of family relationship, patient contact hours, pre-treatment carer burden, patient perceptions of parental caregiving and expressed emotion (EE) were selected, a priori, as potential predictors/moderators of carer burden and emotional distress at 9 months post treatment. Outcomes were analysed separately in mixed-effects random regression models.

RESULTS

Analyses were performed on 260 carers. Only patient perceptions of early maternal criticism predicted reports of lower carer burden at follow-up. However, multiple imputation analysis failed to confirm this result. For treatment moderators: higher levels of carer burden at baseline yielded greater reductions in carer emotional distress at follow-up in the experimental group compared with treatment as usual (TAU). Higher levels of perceived EE moderated greater reductions in carer reports of tension in experimental group, compared with TAU, at follow-up. In younger caregivers (<51 years old), there were greater reductions in levels of worry during the baseline to follow-up period, within the experimental group compared with TAU.

CONCLUSION

The study failed to identify significant treatment predictors of FEP carer outcomes. However, our preliminary findings suggest that optimal treatment outcomes for carers at first episode might be moderated by younger carer age, and carers reporting higher baseline levels of burden, and where patients perceive higher levels of negative effect from caregivers.

Impact of the carer on length of hospital stay for mental health: Results from two Australian surveys

Informal carers play a vital role in supporting Australians living with a mental illness, including during the acute phases of illness; however, little is known about their impact on length of hospital stay. We aimed to investigate the impact of having a carer and of carer burden on length of hospital stay for mental health. Two Australian datasets were used. Data from the 2010 National Survey of High Impact Psychosis (n = 1825) were used to investigate the impact of having versus not having a carer on length of hospital stay for mental health. Data from the UQ Carer Survey 2016 (n = 105), a convenience sample of mental health carers, were used to investigate the impact of weekly hours of care (a measure of objective carer burden) on length of stay. Multiple logistic regression and correlation analyses were performed to investigate the association between carer status/burden and length of stay. Having a carer was associated with a significantly longer length of hospital stay; however, this relationship was no longer significant after adjusting for diagnosis, global functioning, depressive symptoms, deliberate self-harm, mental health outpatient contacts and type of admission. Weekly hours of care did not significantly impact on length of stay. Patients with carers had poorer functioning which may be related to longer stays. Our analysis was not able to look at subgroups of carers with different needs. Future work is required to determine other components of the admission and discharge process where having a carer is influential.

Specialised early intervention teams (extended time) for first episode psychosis

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

The primary objective is to compare extended early intervention (EEIP) specialised team care to usual community mental health care for the treatment of people with first episode psychosis (FEP). The secondary objective is to compare the effectiveness of EEIP specialised team care to standard early intervention (SEIP) specialised team care (i.e. to test whether there is a dose‐response effect).

The last taboo: The experience of violence in first-episode psychosis caregiving relationships

OBJECTIVES

Informal caregiving relationships play an important role in facilitating recovery outcomes in psychosis. The relationship can serve as a source of positive experiences that co-exist alongside common challenges typically associated with mental health problems. People with psychosis, when compared to the general population, are more likely to perpetrate acts of violence, a relationship that is particularly evident during the first psychosis episode. Although victims of service user violence are typically people already known to them, such as informal carers, there remains a lack of understanding about their caring experiences and needs. This study sought to address gaps in the literature by exploring the subjective accounts of informal carers supporting a relative experiencing their first episode of psychosis who has also behaved violently towards them.

DESIGN

A cross-sectional design was employed.

METHODS

Individual semi-structured interviews, which were audio recorded and later transcribed for analyses, were undertaken with a convenience sample of eight carers drawn from a specialist early psychosis service. Interview questions focused on their experiences of patient violence, the subjective impact, and coping strategies. An interpretative phenomenological approach was used to analyse the data.

RESULTS

Participants were mostly living with their relative with psychosis and were typically female, parents, and from a black and minority ethnic background. Data analyses identified seven key themes from participant interviews including the lack of predictability over when the violence occurred, being scared and fearful, keeping quiet about what happens at home and in the caregiving relationship, and staying safe.

CONCLUSIONS

Reports by informal carers about experiencing violence and victimization from their relatives with psychosis are an important issue in some caregiving relationships during the first episode. Developing a more informed understanding of the specific needs of these carers and the caregiving relationship is indicated. The implications for service providers are discussed.

PRACTITIONER POINTS

Carers were exposed to a broad range of patient violence, which included being kicked and having weapons used against them. The violence typically occurred within carers' homes, when no other people were around. Patient violence impacted negatively on carer emotional and physical functioning, which included leaving carers living in fear of their own safety and what might become of their relative. The results highlight the importance of routinely asking first-episode carers about their experience of patient violence. The development of interventions (e.g., identification of early triggers, de-escalation) that are able to take account of the ongoing nature and complexity of the caregiving relationship but are purposefully aimed at supporting carers to remain safe in their relationship should be explored for their impact.
