Patterns of illness and care over the 5 years following onset of psychosis in different ethnic groups; the GAP-5 study

Sociodemographic and clinical predictors of delay to and length of stay with early intervention for psychosis service: findings from the CRIS-FEP study

PURPOSE

We investigated the influence of sociodemographic and clinical characteristics on delay to early intervention service (EIS) and the length of stay (LOS) with EIS.

METHODS

We used incidence data linked to the Clinical Record Interactive Search-First Episode Psychosis (CRIS-FEP) study. We followed the patients from May 2010 to March 2016. We performed multivariable Cox regression to estimate hazard ratios of delay to EIS. Negative binomial regression was used to determine LOS with EIS by sociodemographic and clinical characteristics, controlling for confounders.

RESULTS

343 patients were eligible for an EIS, 34.1% of whom did not receive the service. Overall, the median delay to EIS was 120 days (IQR; 15-1668); and the median LOS was 130.5 days (IQR 0-663). We found that women (adj.HR 0.58; 95%C I 0.42-0.78), living alone (adj.HR: 0.63; 95% CI 0.43-0.92) and ethnicity ('Other': adj.HR 0.47; 95% CI 0.23-0.98) were associated with prolonged delay to EIS. However, family involvement in help-seeking for psychosis (adj.HR 1.37; 95% CI 1.01-1.85) was strongly associated with a shorter delay to EIS. Patients who have used mental health services previously also experienced long delays to EIS.

CONCLUSIONS

Our analyses highlight the link between sociodemographic status, help-seeking behaviours, and delay to EIS. Our findings also show the vulnerability faced by those with a previous mental health problem who later develop psychosis in receiving specialist treatment for psychosis. Initiatives that ameliorate indicators of social disadvantage are urgently needed to reduce health inequalities and improve clinical outcomes.

Advance Statements for Black African and Caribbean people (AdStAC): protocol for an implementation study

BACKGROUND

The UK government committed to legislating for Advance Choice Documents/Advance Statements (ACD/AS) following their recommendation by the Independent Review of the MHA (2018). ACDs/AS are yet to be implemented in routine practice despite evidence and high demand; they are associated with improved therapeutic relationships and a reduction (25%, RR 0.75, CI 0.61-0.93) in compulsory psychiatric admission. Barriers to their implementation are well documented, ranging from low knowledge levels to logistical challenges in accessing the content during episodes of acute care. In the UK this is an issue for Black people, who experience detention rates disproportionately (over three times) higher than those of White British people and have poorer care experiences and outcomes. ACDs/AS allow for Black people to have their concerns heard by mental health professionals in a care system where they often feel their views are ignored. AdStAC aims to improve Black service users' experiences in mental health services in South London by co-producing and testing an ACD/AS implementation resource with Black service users, mental health professionals and carers/supporters of Black service users.

METHODS/DESIGN

The study will take place in South London, England over three phases: 1) formative work through stakeholder workshops; 2) co-production of resources through a consensus development exercise and working groups; and 3) testing of the resources using quality improvement (QI) methods. A lived experience advisory group, staff advisory group and project steering committee will support the study throughout. The implementation resources will comprise: advance choice document/advance statement (ACD/AS) documentation, stakeholder trainings, a manual for mental health professionals to facilitate the processes of creating and revising advance statements, and informatics development.

DISCUSSION

The implementation resources will help increase the likelihood of the new mental health legislation in England being implemented effectively; through aligning evidence-based medicine, policy and law to effectively provide positive clinical, social and financial outcomes for Black people, the National Health Service (NHS) and wider society. This study will likely benefit a wider group of people with severe mental illness, as when marginalised groups who are least engaged, can be supported with these strategies, then the strategies are likely to work for others.

Five-year illness trajectories across racial groups in the UK following a first episode psychosis

PURPOSE

Psychosis disproportionally affects ethnic minority groups in high-income countries, yet evidence of disparities in outcomes following intensive early intervention service (EIS) for First Episode Psychosis (FEP) is less conclusive. We investigated 5-year clinical and social outcomes of young people with FEP from different racial groups following EIS care.

METHOD

Data were analysed from the UK-wide NIHR SUPEREDEN study. The sample at baseline (n = 978) included White (n = 750), Black (n = 71), and Asian (n = 157) individuals, assessed during the 3 years of EIS, and up to 2 years post-discharge (n = 296; Black [n = 23]; Asian [n = 52] and White [n = 221]). Outcome trajectories were modelled for psychosis symptoms (positive, negative, and general), functioning, and depression, using linear mixed effect models (with random intercept and slopes), whilst controlling for social deprivation. Discharge service was also explored across racial groups, 2 years following EIS.

RESULTS

Variation in linear growth over time was accounted for by racial group status for psychosis symptoms-positive (95% CI [0.679, 1.235]), negative (95% CI [0.315, 0.783]), and general (95% CI [1.961, 3.428])-as well as for functioning (95% CI [11.212, 17.677]) and depressive symptoms (95% CI [0.261, 0.648]). Social deprivation contributed to this variance. Black individuals experienced greater levels of deprivation (p < 0.001, 95% CI [0.187, 0.624]). Finally, there was a greater likelihood for Asian (OR = 3.04; 95% CI [2.050, 4.498]) and Black individuals (OR = 2.47; 95% CI [1.354, 4.520]) to remain in secondary care by follow-up.

CONCLUSION

Findings suggest variations in long-term clinical and social outcomes following EIS across racial groups; social deprivation contributed to this variance. Black and Asian individuals appear to make less improvement in long-term recovery and are less likely to be discharged from mental health services. Replication is needed in large, complete data, to fully understand disparities and blind spots to care.

‘It Just Feels Like an Invasion’: Black First-Episode Psychosis Patients’ Experiences With Coercive Intervention and Its Influence on Help-Seeking Behaviours

Studies from the United States and United Kingdom show that Black patients are disproportionately diagnosed with psychosis and receive excess coercive medical intervention. There has been little discussion of this topic in Canada, and of how coercive interventions may have influenced Black patient attitudes towards mental health services. To address these issues, semi-structured interviews were administered to five Black men with first-episode psychosis (FEP) to (a) explore their experiences with coercive interventions and (b) describe how these experiences may have influenced help-seeking behaviours. Interpretative phenomenological analysis (IPA) was used to analyze the data. Four core themes and four additional themes emerged from the interviews. Patients described loneliness, not being heard, police contact and forced medication as influencing their attitudes towards mental health care. Further research is needed to develop reparative strategies to encourage reflection about and awareness of coercive intervention among Black FEP patients.

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.

Suicide rates by ethnic group among patients in contact with mental health services: an observational cohort study in England and Wales

BACKGROUND

Recent evidence on suicide rates among psychiatric patients from minority ethnic backgrounds is scarce. We aimed to examine suicide rates among minority ethnic psychiatric patients and describe their social and clinical characteristics.

METHODS

We did a retrospective observational cohort study on a national case-series of patients in England and Wales who died by suicide within 12 months of contact with mental health services between 2007 and 2018. Data were collected as part of the National Confidential Inquiry into Suicide and Safety in Mental Health. Suicide rates and standardised mortality ratios (SMRs) were estimated for South Asian (Indian, Pakistani, and Bangladeshi), Black African, Black Caribbean, Chinese, and White patients.

FINDINGS

A total of 698 patients in the four minority ethnic groups of South Asian, Black Caribbean, Black African, and Chinese were included (482 [69%] men; 216 [31%] women; mean age 41 years [SD 14·9, range 12-91] and compared with 13 567 White patients (9030 [66·6%] men; 4537 [33·4%] women; mean age 48 years [SD 15·8, range 10-100]). Rates and SMRs for suicide among minority ethnic patients were lower than for White patients (2·73 deaths, 95% CI 2·68-2·78) per 100 000 population. Differences were found between ethnic groups with higher suicide rates in Black Caribbean patients (1·89 deaths [95% CI 1·55-2·23] per 100 000 population) and lower rates in South Asian patients (1·49 deaths [1·33-1·64] per 100 000 population). There was an increase in rates among White patients in 2007-12 followed by a fall but no change among other ethnic groups. Schizophrenia was more common among Black African patients (54%) and Black Caribbean patients (44%), while affective disorder was more common among South Asian patients (41%). Minority ethnic patients overall showed markers of social adversity and received higher intensity care yet were viewed by clinicians as at lower risk than White patients.

INTERPRETATION

Effective approaches to prevention might differ between minority ethnic groups. Clinicians and the services in which they work should be aware of the common and distinct social and clinical needs of minority ethnic patients with mental illness.

Evidence for interventions to promote mental health and reduce stigma in Black faith communities: systematic review

PURPOSE

There are significant documented inequalities for the Black community in the UK in relation to mental health care. Research has also indicated that cultural difference exists in pathways into, and engagement with, mental health services. To reduce inequalities and improve engagement with mental health services, it is important that professionals utilise culturally appropriate community networks to increase mental health awareness and reduce stigma. This systematic review considers research in Black faith settings, with two linked aims to review the evidence for the effectiveness of (i) mental health interventions, and (ii) other health stigma interventions as the latter have been implemented in Black faith settings. The review identified 'active ingredients' of interventions for this population that can be applied in future work. The authors seek to draw from the mental health and wider health stigma literature to inform the design of the ON TRAC project, a collaborative partnership between King's College London, South London and Maudsley NHS Foundation Trust and Black faith community groups in Southwark and Lambeth, London, in this currently under-researched area.

METHODS

A systematic search of ten major medical and social sciences databases was conducted in 2019, for studies on mental health or other health stigma interventions in Black faith settings. PRISMA guidelines were followed and search terms and search strategy ensured all possible studies were identified for review.

RESULTS

The review identified sixteen studies for inclusion. Ten were quantitative studies, four qualitative studies and two systematic reviews. Active ingredients of interventions included utilisation of 'bottom up' development of approaches and mental health champions. Multiple factors were found to influence effective implementation. Co-production and partnership working are key to ensure that an acceptable and accessible intervention is agreed.

CONCLUSION

Evidence for the effectiveness of interventions focused on mental health awareness and stigma reduction in the Black faith community is limited due to the low quality of studies. This review sheds light on the lessons learnt and necessary key requirements for interventions that can guide future projects.

Duration of Untreated Psychosis in First-Episode Psychosis is not Associated With Common Genetic Variants for Major Psychiatric Conditions: Results From the Multi-Center EU-GEI Study

Duration of untreated psychosis (DUP) is associated with clinical outcomes in people with a diagnosis of first-episode psychosis (FEP), but factors associated with length of DUP are still poorly understood. Aiming to obtain insights into the possible biological impact on DUP, we report genetic analyses of a large multi-center phenotypically well-defined sample encompassing individuals with a diagnosis of FEP recruited from 6 countries spanning 17 research sites, as part of the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study. Genetic propensity was measured using polygenic scores for schizophrenia (SZ-PGS), bipolar disorder (BD-PGS), major depressive disorder (MDD-PGS), and intelligence (IQ-PGS), which were calculated based on the results from the most recent genome-wide association meta-analyses. Following imputation for missing data and log transformation of DUP to handle skewedness, the association between DUP and polygenic scores (PGS), adjusting for important confounders, was investigated with multivariable linear regression models. The sample comprised 619 individuals with a diagnosis of FEP disorders with a median age at first contact of 29.0 years (interquartile range [IQR] = 22.0-38.0). The median length of DUP in the sample was 10.1 weeks (IQR = 3.8-30.8). One SD increases in SZ-PGS, BD-PGS, MDD-PGS or IQ-PGS were not significantly associated with the length of DUP. Our results suggest that genetic variation does not contribute to the DUP in patients with a diagnosis of FEP disorders.

Employment and relationship outcomes in first-episode psychosis: A systematic review and meta-analysis of longitudinal studies

As employment and relationship status are important long-term outcomes in individuals with a diagnosis of first episode psychosis (FEP) disorders, there is a need to elucidate more accurately the extent of these social deficits in people with FEP. This in turn can aid treatment planning and policy development ultimately ensuring more complete and sustainable recoveries. We carried out a systematic review and meta-analysis of longitudinal studies in FEP reporting on employment and relationship status during the illness course. Random effects meta-analyses and meta-regression analyses were employed. Seventy-four studies were included with a sample totalling 15,272 (range = 20-1724) FEP cases with an average follow-up duration of 8.3 years (SD = 7.2). 32.5% (95%CI = 28.5-36.9) of people with a diagnosis of FEP disorders were employed and 21.3% (95%CI = 16.5-27.1) were in a relationship at the end of follow-up. Studies from high-income countries and Europe had a higher proportion of people in employment at the end of follow-up compared to middle-income nations and non-European countries. The inverse was found for relationship status. The proportion of people with a diagnosis of FEP in employment decreased significantly with longer follow-up. Living with family, being in a relationship at first contact and Black and White ethnicities were identified as significant moderators of these outcomes. These findings highlight marked functional recovery deficits for people with FEP, although cultural factors need to be considered. They support the need for interventions to improve employment opportunities, and social functioning, both in early psychosis and during the longitudinal illness course.

The influence of risk factors on the onset and outcome of psychosis: What we learned from the GAP study

The GAP multidisciplinary study carried out in South London, recruited 410 first episode of psychosis patients and 370 controls; the aim was to elucidate the multiple genetic and environmental factors influencing the onset and outcome of psychosis. The study demonstrated the risk increasing effect of adversity in childhood (especially parental loss, abuse, and bullying) on onset of psychosis especially positive symptoms. Adverse life events more proximal to onset, being from an ethnic minority, and cannabis use also played important roles; indeed, one quarter of new cases of psychosis could be attributed to use of high potency cannabis. The "jumping to conclusions" bias appeared to mediate the effect of lower IQ on vulnerability to psychosis. We confirmed that environmental factors operate on the background of polygenic risk, and that genetic and environment act together to push individuals over the threshold for manifesting the clinical disorder. The study demonstrated how biological pathways involved in the stress response (HPA axis and immune system) provide important mechanisms linking social risk factors to the development of psychotic symptoms. Further evidence implicating an immune/inflammatory component to psychosis came from our finding of complement dysregulation in FEP. Patients also showed an upregulation of the antimicrobial alpha-defensins, as well as differences in expression patterns of genes involved in NF-κB signaling and Cytokine Production. Being of African origin not only increased risk of onset but also of a more difficult course of illness. The malign effect of childhood adversity predicted a poorer outcome as did continued use of high potency cannabis.

An ethnic-group comparison of caregiver beliefs about early psychotic illness in a UK sample: Implications for evidence-based caregiver interventions

This study aimed to investigate potential ethnic differences in cognitive responses to caregiving in psychosis that might be relevant to the delivery of caregiver interventions for difficulties related to psychosis. We compared cross-sectional outcomes across early-stage caregivers who self-identified as white British (n = 37) and those who self-identified as black African or Caribbean (n = 41) using United Kingdom (UK) census ethnicity criteria. Self-report questionnaires were used to examine caregiver beliefs about psychosis, including the perceived causes, consequences, timeline, the degree of control that patients have over their difficulties, as well as their appraisals of caregiving. Caregivers from black African or Caribbean backgrounds reported a significantly shorter expected duration of illness than white British caregivers. They were also more likely to cite psychosocial causes (e.g., relationship issues), and less likely to cite biological and genetic causes, as their principal explanations for problems. However, overall differences in perceived causes of illness between ethnicities were not significant, despite the power in this sample to detect medium-sized effects. Factors associated with ethnicity may contribute to individual differences in explanatory models of illness and in experiences of caregiving. A degree of sensitivity to the range of views that people might hold about psychosis may help to engage caregivers from diverse ethnic backgrounds.

Hospitalisation and length of hospital stay following first-episode psychosis: systematic review and meta-analysis of longitudinal studies

BACKGROUND

Reducing hospitalisation and length of stay (LOS) in hospital following first episode psychosis (FEP) is important, yet reliable measures of these outcomes and their moderators are lacking. We conducted a systematic review and meta-analysis to investigate the proportion of FEP cases who were hospitalised after their first contact with services and the LOS in a hospital during follow-up.

METHODS

Studies were identified from a systematic search across major electronic databases from inception to October 2017. Random effects meta-analyses and meta-regression analyses were conducted.

RESULTS

81 longitudinal studies encompassing data for 23 280 FEP patients with an average follow-up length of 7 years were included. 55% (95% CI 50.3-60.5%) of FEP cases were hospitalised at least once during follow-up with the pooled average LOS of 116.7 days (95% CI 95.1-138.3). Older age of illness onset and being in a stable relationship were associated with a lower proportion of people who were hospitalised. While the proportion of hospitalised patients has not decreased over time, LOS has, with the sharpest reduction in the latest time period. The proportion of patients hospitalised during follow-up was highest in Australia and New Zealand (78.4%) compared to Europe (58.1%) and North America (48.0%); and lowest in Asia (32.5%). Black ethnicity and longer duration of untreated psychosis were associated with longer LOS; while less severe psychotic symptoms at baseline were associated with shorter LOS.

CONCLUSION

One in two FEP cases required hospitalisation at least once during a 7-year follow-up with an average length of hospitalisation of 4 months during this period. LOS has declined over time, particularly in those countries in which it was previously longest.

Morphological Profiling of Schizophrenia: Cluster Analysis of MRI-Based Cortical Thickness Data

The diagnosis of schizophrenia is thought to embrace several distinct subgroups. The manifold entities in a single clinical patient group increase the variance of biological measures, deflate the group-level estimates of causal factors, and mask the presence of treatment effects. However, reliable neurobiological boundaries to differentiate these subgroups remain elusive. Since cortical thinning is a well-established feature in schizophrenia, we investigated if individuals (patients and healthy controls) with similar patterns of regional cortical thickness form naturally occurring morphological subtypes. K-means algorithm clustering was applied to regional cortical thickness values obtained from 256 structural MRI scans (179 patients with schizophrenia and 77 healthy controls [HCs]). GAP statistics revealed three clusters with distinct regional thickness patterns. The specific patterns of cortical thinning, clinical characteristics, and cognitive function of each clustered subgroup were assessed. The three clusters based on thickness patterns comprised of a morphologically impoverished subgroup (25% patients, 1% HCs), an intermediate subgroup (47% patients, 46% HCs), and an intact subgroup (28% patients, 53% HCs). The differences of clinical features among three clusters pertained to age-of-onset, N-back performance, duration exposure to treatment, total burden of positive symptoms, and severity of delusions. Particularly, the morphologically impoverished group had deficits in N-back performance and less severe positive symptom burden. The data-driven neuroimaging approach illustrates the occurrence of morphologically separable subgroups in schizophrenia, with distinct clinical characteristics. We infer that the anatomical heterogeneity of schizophrenia arises from both pathological deviance and physiological variance. We advocate using MRI-guided stratification for clinical trials as well as case-control investigations in schizophrenia.

Risk of involuntary admission among first-generation ethnic minority groups with early psychosis: a retrospective cohort study using health administrative data

AIMS

Ethnic minority groups often have more complex and aversive pathways to mental health care. However, large population-based studies are lacking, particularly regarding involuntary hospitalisation. We sought to examine the risk of involuntary admission among first-generation ethnic minority groups with early psychosis in Ontario, Canada.

METHODS

Using health administrative data, we constructed a retrospective cohort (2009-2013) of people with first-onset non-affective psychotic disorder aged 16-35 years. This cohort was linked to immigration data to ascertain migrant status and country of birth. We identified the first involuntary admission within 2 years and compared the risk of involuntary admission for first-generation migrant groups to the general population. To control for the role of migrant status, we restricted the sample to first-generation migrants and examined differences by country of birth, comparing risk of involuntary admission among ethnic minority groups to a European reference. We further explored the role of migrant class by adjusting for immigrant vs refugee status within the migrant cohort. We also explored effect modification of migrant class by ethnic minority group.

RESULTS

We identified 15 844 incident cases of psychotic disorder, of whom 19% (n = 3049) were first-generation migrants. Risk of involuntary admission was higher than the general population in five of seven ethnic minority groups. African and Caribbean migrants had the highest risk of involuntary admission (African: risk ratio (RR) = 1.52, 95% CI = 1.34-1.73; Caribbean: RR = 1.58, 95% CI = 1.37-1.82), and were the only groups where the elevated risk persisted when compared to the European reference group within the migrant cohort (African: RR = 1.24, 95% CI = 1.04-1.48; Caribbean: RR = 1.29, 95% CI = 1.07-1.56). Refugee status was independently associated with involuntary admission (RR = 1.16, 95% CI = 1.02-1.32); however, this risk varied by ethnic minority group, with Caribbean refugees having an elevated risk of involuntary admission compared with Caribbean immigrants (RR = 1.72, 95% CI = 1.15-2.58).

CONCLUSIONS

Our findings are consistent with the international literature showing increased rates of involuntary admission among some ethnic minority groups with early psychosis. Interventions aimed at improving pathways to care could be targeted at these groups to reduce disparities.

Reported immigration and medical coercion among immigrants referred to a cultural consultation service

Members of visible minorities are commonly targets of social coercion related to immigration and medical measures. Social coercion is associated with poor mental health outcomes and mistrust of medical services. This study will determine if Afro-Canadian immigrants referred to a Cultural Consultation Service (CCS) in Montreal report more or less medical and immigration coercion compared with other ethnic minorities. We reviewed the charts of 729 referrals to the CCS and gathered data on the 401 patients included in the study. Chi-square statistics examined the relation between minority group and self-reported coercion. Binary logistic regression models controlled for standard sociodemographic variables in addition to ethnicity, language barrier, length of stay in Canada since immigration, refugee claimant status, referral source, presence of psychosis in the main diagnosis, and presence of legal history. Patients were diverse and included 105 Afro-Canadians, 40 Latin Americans, 73 Arab and West Asians, 149 South Asians, and 34 East and Southeast Asians. Being Afro-Canadian was significantly and positively associated with medical coercion (p = .02, 95% CI = 1.15-4.57), while being South Asian was negatively and significantly associated with immigration coercion (p = .03, 95% CI = .29-.93). Members of visible minority communities are not equal in their reported experience of social coercion after arriving to Canada. Future research clarifying pathways to mental health care for immigrants and the experience of new Canadians in immigration and health care settings would give needed context to the findings of this study.

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.

Ethnic variations in compulsory detention under the Mental Health Act: a systematic review and meta-analysis of international data

BACKGROUND

Evidence suggests that black, Asian and minority ethnic (BAME) groups have an increased risk of involuntary psychiatric care. However, to our knowledge, there is no published meta-analysis that brings together both international and UK literature and allows for comparison of the two. This study examined compulsory detention in BAME and migrant groups in the UK and internationally, and aimed to expand upon existing systematic reviews and meta-analyses of the rates of detention for BAME populations.

METHODS

For this systematic review and meta-analysis, we searched five databases (PsychINFO, MEDLINE, Cochrane Controlled Register of Trials, Embase, and CINAHL) for quantitative studies comparing involuntary admission, readmission, and inpatient bed days between BAME or migrant groups and majority or native groups, published between inception and Dec 3, 2018. We extracted data on study characteristics, patient-level data on diagnosis, age, sex, ethnicity, marital status, and occupational status, and our outcomes of interest (involuntary admission to hospital, readmission to hospital, and inpatient bed days) for meta-analysis. We used a random-effects model to compare disparate outcome measures. We assessed explanations offered for the differences between minority and majority groups for the strength of the evidence supporting them. This study is prospectively registered with PROSPERO, number CRD42017078137.

FINDINGS

Our search identified 9511 studies for title and abstract screening, from which we identified 296 potentially relevant full-text articles. Of these, 67 met the inclusion criteria and were reviewed in depth. We added four studies after reference and citation searches, meaning 71 studies in total were included. 1 953 135 participants were included in the studies. Black Caribbean patients were significantly more likely to be compulsorily admitted to hospital compared with those in white ethnic groups (odds ratio 2·53, 95% CI 2·03-3·16, p<0·0001). Black African patients also had significantly increased odds of being compulsorily admitted to hospital compared with white ethnic groups (2·27, 1·62-3·19, p<0·0001), as did, to a lesser extent, south Asian patients (1·33, 1·07-1·65, p=0·0091). Black Caribbean patients were also significantly more likely to be readmitted to hospital compared with white ethnic groups (2·30, 1·22-4·34, p=0·0102). Migrant groups were significantly more likely to be compulsorily admitted to hospital compared with native groups (1·50, 1·21-1·87, p=0·0003). The most common explanations for the increased risk of detainment in BAME populations included increased prevalence of psychosis, increased perceived risk of violence, increased police contact, absence of or mistrust of general practitioners, and ethnic disadvantages.

INTERPRETATION

BAME and migrant groups are at a greater risk of psychiatric detention than are majority groups, although there is variation across ethnic groups. Attempts to explain increased detention in ethnic groups should avoid amalgamation and instead carry out culturally-specific, hypothesis-driven studies to examine the numerous contributors to varying rates of detention.

Ethnic inequalities and pathways to care in psychosis in England: a systematic review and meta-analysis

BACKGROUND

As part of a national programme to tackle ethnic inequalities, we conducted a systematic review and meta-analysis of research on ethnic inequalities in pathways to care for adults with psychosis living in England and/or Wales.

METHODS

Nine databases were searched from inception to 03.07.17 for previous systematic reviews, including forward and backward citation tracking and a PROSPERO search to identify ongoing reviews. We then carried forward relevant primary studies from included reviews (with the latest meta-analyses reporting on research up to 2012), supplemented by a search on 18.10.17 in MEDLINE, Embase, PsycINFO and CINAHL for primary studies between 2012 and 2017 that had not been covered by previous meta-analyses.

RESULTS

Forty studies, all conducted in England, were included for our updated meta-analyses on pathways to care. Relative to the White reference group, elevated rates of civil detentions were found for Black Caribbean (OR = 3.43, 95% CI = 2.68 to 4.40, n = 18), Black African (OR = 3.11, 95% CI = 2.40 to 4.02, n = 6), and South Asian patients (OR = 1.50, 95% CI 1.07 to 2.12, n = 10). Analyses of each Mental Health Act section revealed significantly higher rates for Black people under (civil) Section 2 (OR = 1.53, 95% CI = 1.11 to 2.11, n = 3). Rates in repeat admissions were significantly higher than in first admission for South Asian patients (between-group difference p < 0.01). Some ethnic groups had more police contact (Black African OR = 3.60, 95% CI = 2.15 to 6.05, n = 2; Black Caribbean OR = 2.64, 95% CI = 1.88 to 3.72, n = 8) and criminal justice system involvement (Black Caribbean OR = 2.76, 95% CI = 2.02 to 3.78, n = 5; Black African OR = 1.92, 95% CI = 1.32 to 2.78, n = 3). The White Other patients also showed greater police and criminal justice system involvement than White British patients (OR = 1.49, 95% CI = 1.03 to 2.15, n = 4). General practitioner involvement was less likely for Black than the White reference group. No significant variations over time were found across all the main outcomes.

CONCLUSIONS

Our updated meta-analyses reveal persisting but not significantly worsening patterns of ethnic inequalities in pathways to psychiatric care, particularly affecting Black groups. This provides a comprehensive evidence base from which to inform policy and practice amidst a prospective Mental Health Act reform.

Different types of childhood adversity and 5-year outcomes in a longitudinal cohort of first-episode psychosis patients

Little is known about the impact of different forms of childhood adversity on outcomes in first-episode psychosis (FEP) patients beyond the first year of treatment. We investigated associations between different types of childhood adversity and outcomes of FEP patients over the 5 years following their first contact with mental health services for psychosis. 237 FEP cases aged 18-65 years were followed on average for 5 years after first presentation to psychiatric services in South London, UK. Childhood adversity prior to 17 years of age was assessed at baseline using the Childhood Experience of Care and Abuse Questionnaire (CECA.Q). The results showed that exposure to at least one type of childhood adversity was significantly associated with a lower likelihood of achieving symptomatic remission, longer inpatient stays, and compulsory admission over the 5-year follow-up. There was no evidence though of a dose-response effect. Some specificity was evident. Childhood parental separation was associated with significantly greater likelihood of non-compliance with antipsychotic medications, compulsory admission, and substance dependence. Institutional care was significantly associated with longer total length of inpatient stays; and parental death was significantly associated with compulsory admissions. Clinicians should screen FEP patients for childhood adversity and tailor interventions accordingly to improve outcomes.

Migrant and ethnic minority status as risk indicators for schizophrenia: new findings

PURPOSE OF REVIEW

Arguably, the strongest evidence of an environmental contribution to the cause of psychosis is the increased risk for certain groups of migrants and ethnic minorities. This article summarizes findings published since 2016.

RECENT FINDINGS

Two studies suggested that migration or minority status are proxies for exposure to an inferior social status. A study from Bologna, Italy, showed that the psychosis risk for internal migrants from Southern Italy was as much increased as that for international migrants. A report from New Zealand reported a higher risk for Maoris than for the remainder of the population.Furthermore, a Danish investigation showed that own-group ethnic density of the neighbourhood at age 15 strongly modified the psychosis risk at adult age. This rules out differential mobility during the prodromal phase as an explanation for the ethnic density effect. Preliminary evidence suggests that the psychotogenic effect of migration may be mediated by elevated dopamine in the striatum.

SUMMARY

An increasing body of evidence suggests that the higher psychosis risk for certain migrant or ethnic minority groups is due to an inferior social status. Neuroimaging of the dopamine system appears to be a promising avenue for research into pathogenesis.

Utilising symptom dimensions with diagnostic categories improves prediction of time to first remission in first-episode psychosis

There has been much recent debate concerning the relative clinical utility of symptom dimensions versus conventional diagnostic categories in patients with psychosis. We investigated whether symptom dimensions rated at presentation for first-episode psychosis (FEP) better predicted time to first remission than categorical diagnosis over a four-year follow-up. The sample comprised 193 FEP patients aged 18-65years who presented to psychiatric services in South London, UK, between 2006 and 2010. Psychopathology was assessed at baseline with the Positive and Negative Syndrome Scale and five symptom dimensions were derived using Wallwork/Fortgang's model; baseline diagnoses were grouped using DSM-IV codes. Time to start of first remission was ascertained from clinical records. The Bayesian Information Criterion (BIC) was used to find the best fitting accelerated failure time model of dimensions, diagnoses and time to first remission. Sixty percent of patients remitted over the four years following first presentation to psychiatric services, and the average time to start of first remission was 18.3weeks (SD=26.0, median=8). The positive (BIC=166.26), excited (BIC=167.30) and disorganised/concrete (BIC=168.77) symptom dimensions, and a diagnosis of schizophrenia (BIC=166.91) predicted time to first remission. However, a combination of the DSM-IV diagnosis of schizophrenia with all five symptom dimensions led to the best fitting model (BIC=164.35). Combining categorical diagnosis with symptom dimension scores in FEP patients improved the accuracy of predicting time to first remission. Thus our data suggest that the decision to consign symptom dimensions to an annexe in DSM-5 should be reconsidered at the earliest opportunity.
