The young adult service: An evaluation of a youth mental health service in the independent sector in Ireland.

AIMS: Increasing concerns about the specific needs and rates of mental illness among young adults have spurred the development of youth mental health services. Yet few outcome studies exist. This study aims to evaluate a young adult service in an independent mental health sector in Ireland. METHODS: This is a service evaluation using a retrospective, descriptive and naturalistic study design. Routine demographic, diagnostic and service usage data were collected at entry into the service. Outcomes were recorded at discharge from the service using the Clinical Global Impression (CGI) improvement scores. Factors associated with better or worse outcomes were analyzed. RESULTS: Five hundred and sixty-seven young adults were assessed and managed during a 3-year period by the Young Adult Service. Their characteristics fell midway between adolescent and adult mental health service populations. They had high levels of Axis I & II co-morbidities reflecting the complex and fluid nature of emerging conditions in this age group. The majority (62.8%) had clinically improved by the end of follow-up. Outcomes were significantly better in those who were hospitalized, prescribed psychotropic medication, received 1:1 psychology sessions and attended a group-based psychology program or group program for specific disorders. One hundred and sixty-six patients (29.3%) dropped out of follow-up. Drop out was associated with longer time spent in the service, being treated solely in the community, without medication, not having a developmental disorder and not transferring from CAMHS. CONCLUSIONS: This study demonstrates that it is possible to establish an effective youth mental health service with favourable outcomes within a broader mental health system. It provides a benchmark for similar services, bridging the gap between adolescent and adult mental health services.

The relationship between ethnicity and service access, treatment uptake and the incidence of psychosis among people at ultra high risk for psychosis.

Black ethnicity is associated with increased risk for psychosis in South London. This study explored the distribution of ethnicity among services users at ultra high risk for psychosis (UHR) and examined the influence of ethnicity on service access, treatment uptake and incidence of psychosis. The ethnic distribution of 228 people at UHR for psychosis, seen in an early detection clinical service over 10 years, was compared with 146 people with first episode psychosis from the same geographic region and census figures for the local population. Black service users were significantly over-represented in the UHR group compared to the background population (34% vs 21%; p < 0.05); but less so than in the first episode sample (58% vs 19%; p < 0.05). Within the UHR sample, there was no strong evidence of differences between ethnic groups in the types of treatment provided, nor in the rate of transition to psychosis over 2 years. The absence of differences between ethnic groups in rates of transition to psychosis raises the possibility that access to mental health care at the high risk stage might have reduced the influence of ethnicity on the incidence of psychosis in this sample. This would need to be replicated in a larger sample.

Outcome and recovery in first-episode psychosis.

There is now a good body of evidence about factors that determine outcome and recovery in a first episode of psychosis. However, so far, this is of limited benefit when making predictions at an individual level. Treatment protocols are one size fits all and the recommended duration of medication remains unclear. What is needed is a more sophisticated approach to predicting outcomes and tailoring treatment options to the individual. Removing predisposing factors is an important aspect of this.

Impact of crime victimization on initial presentation to an early intervention for psychosis service and 18-month outcomes.

AIM: To investigate the clinical and social correlates of a lifetime history of crime victimization among first-episode psychosis patients at entry to an Early Intervention Service and following 18 months of specialist care. METHODS: Face-to-face interviews were conducted with 149 individuals who presented to an Early Intervention Service for the first time with psychosis in the London borough of Lambeth, UK. A range of demographic and clinical measures were completed including self-reported history of victimization along with the type of crime and its subjective effect on the patient. Clinical and functional outcomes at 18-month follow up were ascertained from clinical case notes by a psychiatrist. RESULTS: A large proportion of patients (n = 64, 43%) reported a history of crime victimization. This was associated with significantly higher levels of depression and substance misuse at initial presentation. Being a victim of a crime was not significantly associated with poorer clinical or functional outcomes after 18 months of specialist care. However, non-significant differences were found for those who reported crime victimization in terms of their increased use of illegal substances or having assaulted someone else during the follow-up period. CONCLUSION: Past experience of being a victim of crime appears to be common in patients presenting for the first time with psychosis and is associated with increased likelihood of comorbidity. Thus, Early Intervention Services should consider screening for past victimization and be prepared to deal with comorbid problems. The impact of crime victimization on clinical and functional outcomes requires investigation over a longer period of time.

Five-fold increased risk of relapse following breaks in antipsychotic treatment of first episode psychosis.

BACKGROUND: A key problem in the management of first episode psychosis is that patients are often reluctant to take antipsychotic medication, especially once their presenting symptoms have resolved. Clinicians may be tempted to trial a 'break in treatment' in such patients. AIM: To assess the impact of interruptions in the antipsychotic treatment of first episode psychosis. METHOD: Treatment adherence and clinical course were assessed during the 18months following presentation in 136 consecutive patients with a first episode of psychosis in 2003-2005 by a systematic retrospective casenote review. Regression analyses were used to examine the time to remission and the risk of relapse in patients who had stopped antipsychotics for one month or more. RESULTS: There were breaks in antipsychotic treatment of ≥1month in more than half of the patients (n=73; 58%). When these occurred before they had recovered (n=22; 17%), the time to remission was almost twice as long as in patients in whom treatment was continuous (t=2.9, P=0.01). Patients in whom treatment was interrupted were 5 times more likely to have relapsed than those in whom it was continuous (p=0.0001, 95%CI 2.1-11). The mean time to relapse following an interruption in treatment was 3months. CONCLUSION: If the treatment of first episode psychosis with antipsychotic medication is stopped for a month or more, remission may be delayed and the risk of relapse following remission may be substantially increased.

Duration of untreated psychosis and need for admission in patients who engage with mental health services in the prodromal phase.

BACKGROUND: It is unknown whether prodromal services improve outcomes in those who go on to develop psychosis, and whether these patients are demographically different from the overall first-episode population. AIMS: To compare sociodemographic features, duration of untreated psychosis, hospital admission and frequency of compulsory treatment in the first year after the onset of psychosis in patients who present to prodromal services with patients who did not present to services until the first episode of psychosis. METHOD: We compared two groups of patients with first-episode psychosis: one who made transition after presenting in the prodromal phase and the other who had presented with a first episode. RESULTS: The patients who had presented before the first episode were more likely to be employed and less likely to belong to an ethnic minority group. They had a shorter duration of untreated psychosis, and were less likely to have been admitted to hospital and to have required compulsory treatment. CONCLUSIONS: Patients who develop psychosis after being engaged in the prodromal phase have a better short-term clinical outcome than patients who do not present until the first episode. Patients who present during first episodes may be more likely to have sociodemographic features associated with relatively poor outcomes.

Identifying aspects of neighbourhood deprivation associated with increased incidence of schizophrenia.

BACKGROUND: Several studies have found an association between area deprivation and incidence of schizophrenia. However, not all studies have concurred and definitions of deprivation have varied between studies. Relative deprivation and inequality seem to be particularly important, but which aspects of deprivation or how this effect might operate is not known. METHODS: The Lambeth Early Onset case register is a database of all cases of first episode psychosis aged 16 to 35years from the London Borough of Lambeth, a highly urban area. We identified 405 people with first onset schizophrenia who presented between 2000 and 2007. We calculated the overall incidence of first onset schizophrenia and tested for an association with area-level deprivation, using a multi-domain index of deprivation (IMD 2004). Specific analyses into associations with individual sub-domains of deprivation were then undertaken. RESULTS: Incidence rates, directly standardized for age and gender, were calculated for Lambeth at two geographical levels (small and large neighbourhood level). The Poisson regression model predicting incidence rate ratios for schizophrenia using overall deprivation score was statistically significant at both levels after adjusting for ethnicity, ethnic density, population density and population turnover. The incidence rate ratio for electoral ward deprivation was 1.03 (95% CI=1.004-1.04) and for the super output area deprivation was 1.04 (95% CI=1.02-1.06). The individual domains of crime, employment deprivation and educational deprivation were statistically significant predictors of incidence but, after adjusting for the other domains as well as age, gender, ethnicity and population density, only crime and educational deprivation, remained statistically significant. Low income, poor housing and deprived living environment did not predict incidence. CONCLUSIONS: In a highly urban area, an association was found between area-level deprivation and incidence of schizophrenia, after controlling for age, gender, ethnicity and population density; high crime and low levels of education accounted for this. As both of these are potentially modifiable, this suggests a possible means to reduce the incidence of schizophrenia.

Ethnic variations in pathways into early intervention services for psychosis.

BACKGROUND: Ethnic variations have previously been identified in the duration of untreated psychosis (DUP) and pathways into psychiatric services. These have not been examined in the context of early intervention services, which may alter these trajectories. AIMS: To explore ethnic differences in the nature and duration of pathways into early intervention services. METHOD: In a naturalistic cohort study, data were collected for 1024 individuals with psychotic disorders accepted for case management by eight London early intervention services. RESULTS: Duration of untreated psychosis was prolonged in the White British group compared with most other ethnic groups. White British individuals were more likely to make contact with their general practitioner and less likely to be seen within emergency medical services. All Black patient groups were more likely than their White British counterparts to experience involvement of criminal justice agencies. CONCLUSIONS: Variations continue to exist in how and when individuals from different ethnic groups access early intervention services. These may account for disparities in DUP.

Initial diagnosis and treatment in first-episode psychosis: can an operationalized diagnostic classification system enhance treating clinicians' diagnosis and the treatment chosen?

AIM: Diagnosis during the initial stages of first-episode psychosis is particularly challenging but crucial in deciding on treatment. This is compounded by important differences in the two major classification systems, International Classification of Diseases, 10th revision (ICD-10) and Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). We aimed to compare the concordance between an operationalized diagnosis using Operational Criteria Checklist (OPCRIT) and treating clinician-generated diagnosis in first episode psychosis diagnosis and its correlation with treatment prescribed. METHODS: Operationalized polydiagnostic assessments were conducted on 150 first-episode psychosis patients using OPCRIT. OPCRIT generated ICD-10, DSM-IV and treating clinician diagnoses were compared. The association between these diagnoses and choice of treatment was evaluated. RESULTS: General agreement between the three classification systems was moderate to good, with kappa values between 0.460 and 0.674. There was a higher frequency of schizophrenia diagnosis in ICD-10 (n = 85) comparing to DSM-IV (n = 45) and similar in clinical diagnosis (n = 76), with moderate to good agreement between classifications (kappa between 0.602 and 0.731). No significant differences were found for ratings of psychotic depressive and manic/bipolar disorders with psychosis, with affective disorders having the higher agreement. Heterogeneous group of 'other disorders' achieved a kappa value from 0.250 (DSM-IV/ICD-10) to 0.566 (DSM-IV/clinical diagnosis). CONCLUSION: Despite the challenges in first-episode psychosis diagnosis, it is possible to have a good agreement between OPCRIT-generated (DSM-IV and ICD-10) diagnoses and clinician based diagnoses, although some differences exist. The choice of psychopharmacological treatment prescribed matches well with these operationalized diagnoses.

A diagnostic dilemma between psychosis and post-traumatic stress disorder: a case report and review of the literature.

INTRODUCTION: Post-traumatic stress disorder is defined as a mental disorder that arises from the experience of traumatic life events. Research has shown a high incidence of co-morbidity between post-traumatic stress disorder and psychosis. CASE PRESENTATION: We report the case of a 32-year-old black African woman with a history of both post-traumatic stress disorder and psychosis. Two years ago she presented to mental health services with auditory and visual hallucinations, persecutory delusions, suicidal ideation, recurring nightmares, hyper-arousal, and initial and middle insomnia. She was prescribed trifluoperazine (5 mg/day) and began cognitive-behavioral therapy for psychosis. Her psychotic symptoms gradually resolved over a period of three weeks; however, she continues to experience ongoing symptoms of post-traumatic stress disorder. In our case report, we review both the diagnostic and treatment issues regarding post-traumatic stress disorder with psychotic symptoms. CONCLUSIONS: There are many factors responsible for the symptoms that occur in response to a traumatic event, including cognitive, affective and environmental factors. These factors may predispose both to the development of post-traumatic stress disorder and/or psychotic disorders. The independent diagnosis of post-traumatic stress disorder with psychotic features remains an open issue. A psychological formulation is essential regarding the appropriate treatment in a clinical setting.

Very low-dose risperidone in first-episode psychosis: a safe and effective way to initiate treatment.

Patients experiencing a first psychotic episode have high rates of extrapyramidal symptoms (EPSs) when treated with the doses of neuroleptics used in multiepisode or chronic schizophrenia. There is some evidence that lower doses may be equally, if not more, effective but less toxic in this population. Here, we report the results of a biphasic open label trial designed to assess the efficacy, safety, and tolerability of low-dose (2-4 mg/day) risperidone treatment in a group of 96 first-episode nonaffective psychosis patients. At the end of the trial, 62% of patients met the response criteria although approximately 80% had achieved a response at some time during the study. Reports of EPS remained low, and there were no dystonic reactions. We conclude that even at a dose of 2 mg/day, risperidone was highly effective in reducing acute symptomatology in a real world sample of young first-episode psychosis patients.

Esquire trial: efficacy and adverse effects of quetiapine versus risperidone in first-episode schizophrenia.

OBJECTIVE: To compare the efficacy and adverse effect profiles of 2 widely used atypical antipsychotics in the short-term phase of first-episode schizophrenia in patients who were treatment-naive. A secondary objective was to establish the effective dose of these drugs in this context. METHODS: A total of 72 patients with a first episode of schizophreniform psychosis (schizophrenia spectrum disorder) with less than 2 weeks of exposure to antipsychotic medication were randomized to quetiapine or risperidone in a single-blind 12-week controlled trial. Psychopathologic diagnoses and adverse effects were assessed by blinded raters at 4 weekly intervals. Medication was administered by a specialized clinical team following dosing guidelines. Data were analyzed using an intention-to-treat paradigm. RESULTS: Both quetiapine and risperidone were associated with a reduction in immediate symptoms and relatively few adverse effects other than weight gain. There was no statistically significant difference between the 2 compounds in adverse effects, relative efficacies, or adherence to treatment. The median (SD) time to cessation for patients randomized to quetiapine was 65.3 (41.85) days and that for risperidone was 82.5 (44.88) days. There was no statistically significant difference between time to discontinuation for the 2 compounds. The mean daily doses prescribed were 375 mg of quetiapine and 2.72 mg of risperidone. CONCLUSIONS: Quetiapine and risperidone are both effective treatments in first-episode schizophrenia at doses lower than those used in patients with long-term schizophrenia and are similar in efficacy and the incidence of adverse effects.

Efficacy of atypical v. typical antipsychotics in the treatment of early psychosis: meta-analysis.

BACKGROUND: There is an ongoing debate about the use of atypical antipsychotics as a first-line treatment for first-episode psychosis. AIMS: To examine the evidence base for this recommendation. METHOD: Meta-analyses of randomised controlled trials in the early phase of psychosis, looking at long-term discontinuation rates, short-term symptom changes, weight gain and extrapyramidal side-effects. Trials were identified using a combination of electronic (Cochrane Central, EMBASE, MEDLINE and PsycINFO) and manual searches. RESULTS: Fifteen randomised controlled trials with a total of 2522 participants were included. No significant differences between atypical and typical drugs were found for discontinuation rates (odds ratio (OR) = 0.7, 95% CI 0.4 to 1.2) or effect on symptoms (standardised mean difference (SMD) = -0.1, 95% CI -0.2 to 0.02). Participants on atypical antipsychotics gained 2.1 kg (95% CI 0.1 to 4.1) more weight than those on typicals, whereas those on typicals experienced more extrapyramidal side-effects (SMD = -0.4, 95% CI -0.5 to -0.2). CONCLUSIONS: There was no evidence for differences in efficacy between atypical and typical antipsychotics, but there was a clear difference in the side-effect profile.

Effect of early intervention on 5-year outcome in non-affective psychosis.

BACKGROUND: Early specialised care may improve short-term outcome in first-episode non-affective psychosis, but it is unclear if these benefits endure. AIMS: To assess the long-term effect of early intervention in psychosis. METHOD: Individuals with first-episode psychosis were randomised to specialised care or care as usual (trial number: ISRCTN73679874). Outcome after 5 years was assessed by case-note review. RESULTS: There were no significant differences in the admission rate (coefficient 0.096, 95% CI -0.550 to 0.742, P = 0.770) or the mean number of bed days (coefficient 6.344, 95% CI -46 to 58.7, P = 0.810). CONCLUSIONS: These findings that specialist intervention did not markedly improved outcome at 5 years accord with those from a larger OPUS study. The sample size of this study was small and these results should be generalised with caution. More research is needed.

Cost-effectiveness of an early intervention service for people with psychosis.

BACKGROUND: There is concern that delaying treatment for psychosis may have a negative impact on its long-term course. A number of countries have developed early intervention teams but there is limited evidence regarding their cost-effectiveness. AIMS: To compare the costs and cost-effectiveness of an early intervention service in London with standard care. METHOD: Individuals in their first episode of psychosis (or those who had previously discontinued treatment) were recruited to the study. Clinical variables and costs were measured at baseline and then at 6- and 18-month follow-up. Information on quality of life and vocational outcomes were combined with costs to assess cost-effectiveness. RESULTS: A total of 144 people were randomised. Total mean costs were 11,685 pounds sterling in the early intervention group and 14,062 pounds sterling in the standard care group, with the difference not being significant (95% CI -8128 pounds sterling to 3326 pounds sterling). When costs were combined with improved vocational and quality of life outcomes it was shown that early intervention would have a very high likelihood of being cost-effective. CONCLUSIONS: Early intervention did not increase costs and was highly likely to be cost-effective when compared with standard care.

Routine evaluation in first episode psychosis services: feasibility and results from the MiData project.

BACKGROUND: Early intervention services (EIS) for psychosis are becoming widespread. Structured methods of assessment are advocated in these services, but a consensus is still needed on a package of measures with good psychometric properties that is feasible and reliable for routine use in this setting. METHODS: A computerised assessment package (MiData) was designed to provide clinicians with easy-to-understand feedback about clients' progress and to allow evaluation of the whole service for both audit and research purposes. Core areas include symptoms, duration of untreated psychosis (DUP), pathways into care, social functioning, and substance misuse at initial intake and annually thereafter. RESULTS: MiData has been adopted by EIS throughout London and in some other centres. Baseline data are now available regarding 533 first-episode psychosis patients who presented to 8 London teams. The completeness of the data varied across teams and measures, with fullest completion for sociodemographic data (99% on some measures) and poorest for DUP. The average London EIS client is male, single, unemployed and comes from Black or Minority Ethnic group. Most (70%) demonstrated poor social functioning at intake, over a third (38%) reported substance abuse problems and 23% had harmed themselves or others in the previous 6 months. CONCLUSIONS: MiData provides a clinician-friendly system of evaluating first-episode psychosis services but requires further refinement and dedicated resources to improve completion rates. This method of collecting routine data is of use to clinicians, managers, health service researchers and commissioners and potentially it may enable naturalistic comparisons between different models of care.

The Lambeth Early Onset Crisis Assessment Team Study: general practitioner education and access to an early detection team in first-episode psychosis.

BACKGROUND: There are few evaluations of strategies to improve rates of early detection and treatment of patients with first-episode psychosis. AIMS: To evaluate the effectiveness of a general practitioner (GP) education programme and an early detection assessment team (the Lambeth Early Onset Crisis Assessment Team; LEO CAT) in reducing delays in accessing treatment for first-episode psychosis patients. METHOD: 46 clusters of GP practices randomised to GP education in early detection with direct access to LEO CAT v. care as usual. Primary outcome measures were GP referral rates, duration of untreated psychosis (DUP) and delays in receiving treatment. RESULTS: 150 patients with first-episode psychosis were recruited; 113 were registered with the study GPs, who referred 54 (47.7%) directly to mental health services. Significantly more intervention group GPs (86.1% v. 65.7%) referred their patients directly to mental health services and fewer patients experienced long delays in receiving treatment. However, their overall DUP was unaffected. CONCLUSIONS: Educating GPs improves detection and referral rates of first-episode psychosis patients. An early detection team reduces the long delays in initial assessment and treatment. However, these only impact on the later phases of the DUP. Broader measures, such as public health education, are needed to reduce the earlier delays in DUP.

Lambeth Early Onset (LEO) and Outreach & Support in South London (OASIS) service.

AIM: To establish a comprehensive phase-oriented early intervention service for young people with early psychosis in south London and to evaluate its effectiveness in delivering user friendly interventions and better outcomes. METHODS: The Lambeth Early Onset (LEO) and Outreach & Support in South London (OASIS) service has been developed incrementally over the last 6 years into 4 teams each addressing one of the phases of early psychosis: (i) prodrome/ultra-high risk (ii) untreated psychosis (c) acute inpatient treatment and (d) recovery/ relapse prevention phases. Research and evaluation have been integral to each team's development with three of the teams configured as Randomised Controlled Trials. RESULTS: During the first 6 years, 1255 young people in Lambeth were referred for assessment (963 to LEO and 292 to OASIS). Of them 578 were diagnosed as suffering from first episode psychosis (some before or after they presented to OASIS), 450 have been followed up in Lambeth by the LEO Community Team and 40% discharged back to GPs in remission at the end of their two years of follow-up. Compared to standard service, patients' delays in accessing treatment are less, and outcomes at 18 months are better. CONCLUSIONS: The LEO and OASIS service now provide most of the mental health service requirements for young people with early psychosis in Lambeth. It represents good value for money and improved outcomes for clients. Further interventions are planned and ultimately it will be possible to evaluate the impact of each incremental step in the service's development.
