Purpose: Migrant and ethnic minority populations exhibit a higher incidence of psychotic disorders. The Ultra-High Risk for psychosis (UHR) paradigm provides an opportunity to explore the stage at which such factors influence the development of psychosis. In this systematic review, we collate and appraise the literature on the association between ethnicity and migrant status and the rate of identification of individuals at UHR, as well as their rate of transition to psychosis. Methods: We conducted a systematic review in the Ovid Medline, PsychINFO, Pubmed, CINAHL and EMBASE databases according to PRISMA guidelines. We included studies written in English that included an UHR cohort, provided a measure of ethnicity or migrant status, and examined the incidence, rate, or risk of UHR identification or transition to psychosis. Results: Of 2182 unique articles identified, seven fulfilled the criteria. One study found overrepresentation of UHR individuals from black ethnic groups, while another found underrepresentation. Two studies found increased rates of transition among certain ethnic groups and a further two found no association. Regarding migrant status, one study found that first-generation migrants were underrepresented in an UHR sample. Lastly, a lower transition rate in migrant populations was identified in one study, while two found no association. Conclusion: Rates of UHR identification and transition according to ethnic and migrant status were inconsistent and insufficient to conclusively explain higher incidences of psychotic disorders among these groups. We discuss the clinical implications and avenues for future research, which is required to clarify the nature of the associations.

Certain migrant groups have been identified as being at increased risk of developing a psychotic disorder, but there is limited research on the outcomes for migrants who develop a first episode of psychosis (FEP). We investigated symptomatic outcomes (remission and relapse rates), functional outcomes (occupational status and relationships) and service utilization (hospital admission and engagement). Young people, aged between 15 and 24, who presented with FEP to the Early Psychosis Prevention and Intervention Centre (EPPIC) at Orygen between 01.01.11 and 31.12.16 were included. Place of birth was recorded at the time of presentation. To determine remission, symptoms were scored at three-month intervals using the short-form Scale for the Assessment of Positive Symptoms. A total of 1220 young people presented with FEP over the six-year period (mean age = 19.6 ± 2.8). Of these, 58.1% were male and 24.0% were first-generation migrants. While there was no difference in overall rates of admission after presentation, migrants were more likely to have an involuntary admission after presentation (31.4% vs. 24.6%, aHR = 1.54, 95% CI [1.19, 2.01]) and this risk was greatest for African migrants (HR = 1.98, 95% C.I. [1.37, 2.86]. The rates of remission and relapse were similar in migrants and those born in Australia and there was no difference in functional outcomes, such as employment rates at follow-up. The outcomes for migrants who experience FEP appear to be largely similar to those for the Australian-born population. Our finding that a greater rate of involuntary admission for migrants at presentation supports existing literature and needs further exploration to improve clinical care.

Individuals affected by psychotic disorders frequently disengage from mental health services, although reports of this rate in the literature have ranged from 6 to 60%. One of the potential explanations for the large variation is that studies have adopted different definitions. Without a universal definition it is challenging to compare rates and factors leading to disengagement across studies. This systematic review aims to identify and compare how disengagement from psychosis services has been defined, measured and operationalised in the literature to date. A systemic literature search of the PubMed, PsycINFO and CINAHL databases was completed following the PRISMA guidelines for systematic reviews. 1506 Studies were identified, of which 30 were eligible to be included. It was found that disengagement was operationalized as either a categorical or continuous variable across studies, with 18 studies classifying it as a categorical, binary variable. Only four studies applied a time period over which disengagement was said to occur, and only four studies used an instrument to measure or predict disengagement. Few studies considered similar factors in their definition, when this occurred it was because the papers came from the same research group. To truly understand the phenomenon of disengagement, studies need to have a comparable outcome variable. The need for consensus on a gold standard definition of disengagement that considers the full breadth of its complexity remains. A potential process for establishing a definition that includes set parameters, agreed upon terminology and time periods of assessment is discussed.

A core component of treatment provided by early intervention for psychosis (EI) services is ensuring individuals remain successfully engaged with the service. This ensures they can receive the care they may need at this critical early stage of illness. Unfortunately, rates of disengagement are high in individuals with a first episode of psychosis (FEP), representing a major barrier to effective treatment. This study aimed to ascertain the rates and determinants of disengagement and subsequent re-engagement of young people with FEP in a well-established EI service in Melbourne, Australia. This cohort study involved all young people, aged 15–24, who presented to the Early Psychosis Prevention and Intervention Centre (EPPIC) service with FEP between 1st January 2011 and 1st September 2014. Data were collected retrospectively from clinical files and electronic records. Cox regression analysis was used to identify determinants of disengagement and re-engagement. A total of 707 young people presented with FEP during the study period, of which complete data were available for 700. Over half of the cohort (56.3%, N = 394) disengaged at least once during their treatment period, however, the majority of these individuals (85.5%, N = 337) subsequently re-engaged following the initial episode of disengagement. Of those who disengaged from the service, 54 never re-engaged, representing 7.6% of the total cohort. Not being in employment, education or training, not having a family history of psychosis in second degree relatives and using cannabis were found to be significant predictors of disengagement. No significant predictors of re-engagement were identified. In this study, the rate of disengagement in young people with first-episode psychosis was higher than found previously. Encouragingly, rates of re-engagement were also high. The concept of disengagement from services might be more complex than previously thought with individuals disengaging and re-engaging a number of times during their episode of care. What prompts individuals to re-engage with services needs to be better understood.

Involuntary admission legislation and rates differ greatly throughout the European Union Member States. In Ireland, the Mental Health Act 2001 has introduced significant changes in the care for patients admitted involuntarily, including mental health tribunals that review the involuntary admission orders. To investigate (1) people's perception of the involuntary admission, (2) awareness of legal rights and perception of tribunal, (3) the impact of being admitted involuntarily on the relationship with their family, consultant psychiatrist and prospects for future employment. Over a 15-month period patients admitted involuntarily to a Dublin Hospital were interviewed using a semi structured interview. Eighty-one people participated in the study. Seventy-two percent of patients believed that their involuntary admission was necessary at the time and this was associated with greater insight into illness. A total of 77.8% of patients felt that the treatment they received had been beneficial. A total of 86.4% of patients were aware that they had been admitted involuntarily and 45.5% of patients found it easier to accept that they had been admitted involuntarily as their case was reviewed by a tribunal. A total of 27.5% experienced a negative impact upon the relationship with their family as a result of the involuntary admission, while for 15% there was a positive impact. For 26.6% of patients the doctor-patient relationship was negatively impacted upon and a third felt their prospects for employment could be affected. The majority of patients reflect positively on their involuntary admission and this opportunity should be used to engage patients in follow-up treatment.

PURPOSE: The incidence of psychotic disorders varies according to the geographical area, and it has been investigated whether neighbourhood level factors may be associated with this variation. The aim of this systematic review is to collate and appraise the literature on the association between social deprivation and the incidence or risk for psychotic disorders. METHOD: A systematic review was conducted, and studies were included if they were in English, provided a measure of social deprivation for more than one geographically defined area and examined either the correlation, rate ratio or risk of psychotic disorder. A defined search strategy was undertaken with Medline, CINAHL Plus and PsychInfo databases. RESULTS: A total of 409 studies were identified in the search, of which 28 fulfilled the inclusion criteria. Of these, four examined the association between social deprivation at the time of birth, three examined the putative prodrome of psychosis or those at ultra-high risk (UHR) for psychosis, and 23 examined the time at presentation with a first episode of psychosis (FEP) (one study examined two time points and one study included both UHR and FEP). Three of the studies that examined the level of social deprivation at birth found an association with a higher risk for psychotic disorders and increased social deprivation. Seventeen of the 23 studies found that there was a higher risk or rate of psychotic disorders in more deprived neighbourhoods at the time of presentation; however, adjusting for individual factors tended to weaken this association. Limited research has been conducted in the putative prodromal stage and has resulted in conflicting findings. CONCLUSIONS: Research conducted to date has not definitively identified whether the association is a result of social causation or social drift; however, the findings do have significant implications for service provision, such as the location and access of services.
