European status and perspectives on early detection and intervention in at-risk mental state and first episode psychosis: Viewpoint from the EPA section for prevention of mental disorders

Clinical high risk for psychosis in children and adolescents: A meta-analysis of transition prevalences

The strategic value of early, preventive intervention in psychosis has been a catalytic stepping stone to promoting early intervention in Mental Health. Central to such momentum is the construct of clinical high risk states for psychosis (CHR). While CHR emerge in developmental years, the meta-analytical risk of psychosis among children and adolescents (age 9-18 years) at CHR is still unknown. We conducted a meta-analysis according to PRISMA guidelines including all studies that assessed CHR in children and adolescents (age ≤ 18 years) with validated instruments and provided follow-data on transition to psychosis up to December 31, 2018. We identified 11 eligible studies. Mean age was 15.8 ± 0.8 years, range: 13.8 to 16.8. Transition to psychosis occurred in 93 CHR subjects out of 533 that were enrolled at inception, over a follow-up period ranging from 6 to 72 months. Conversion prevalence was 17.5% (95% CI: 9.9% to 26.5%) in the random-effects model (Q = 30.9; p < .001; I² = 68%), and slightly lower (16.0; 12.9% to 19.5%) in the fixed-effect model. Gender ratio, the criteria used to diagnose the CHR status, and quality of studies had an impact on the estimates of conversion prevalence in the intention-to-treat model without the outlier. Studies of fair quality produced lower estimates of conversion prevalence (11%; 95% CI: 2% to 24%) than those produced by studies of good quality (19%; 95% CI: 11% to 28%). These findings suggest that CHR in adolescence presents commensurable transition prevalences to those found in adult samples, confirming the relevance of CHR criteria for timely risk inception in developmental years. Outcomes other than transition to psychosis (e.g. remission, persistent CHR, socio-functional status or treatment responses) were not systematically reported thereby preventing further, more sophisticated, prognostic stratifications.

Help-Seekers in an Early Detection of Psychosis Service: The Non-cases

Purpose: Enhancing early help-seeking is important for early intervention in psychosis. However, knowledge is limited about those help-seekers who are not initially found to have psychotic symptoms when assessed in services aiming at psychosis detection and, thus, deemed ineligible for early intervention of psychosis programs. We aimed to examine clinical diagnostic and socioeconomic pathways of help-seekers accessing an early detection of psychosis service with referral-free access. Specific focus was on the help-seekers initially assessed not to have psychotic symptoms, considered the non-cases, and to examine potential differences and similarities between non-cases and cases (i.e., those initially assessed to have psychotic symptoms). Methods: We followed 450 help-seekers assessed by a free-of-referral early detection of psychosis team in national registers for up to 4 years. We examined clinical diagnoses and status of not in education, employment, or training (NEET) before and after contact with the team. Results: Of the non-cases, 46% were referred to mental health services by the early detection of psychosis team for evaluation of other mental disorders, and 15% of these were subsequently diagnosed with a non-affective psychotic disorder during follow-up of 12-52 months. Prior to current help-seeking, 39% (n = 174) of the help-seekers had had contact with other mental health services. Nearly a quarter of help-seekers were NEETs at the time of assessment; the number increased during follow-up, both for cases and non-cases. Of the cases, 58% were subsequently clinically diagnosed by mental health services. Those seeking help who had no previous contact with mental health services were more frequently diagnosed with a non-affective psychotic disorder during follow-up (p = 0.05). Conclusion: Referral-free services to promote early detection of psychosis seem a valuable add-on to established pathways, allowing early intervention in psychosis. Our results point to an unmet mental health service need among non-cases; overall, in our sample, independent of case status, social functioning was markedly affected. Our results have implications for future focus in early detection of psychosis. Offering intervention to non-cases within the service has the potential to be cost effective, e.g., if a timely and targeted intervention reduces repeated contacts in other mental health services and social services.

Survey of the European Psychiatric Association on the European status and perspectives in early detection and intervention in at-risk mental state and first-episode psychosis

AIM

Early detection/early intervention (ED/EI) programmes have been inconsistently implemented throughout Europe. We evaluated the ED/EI service distribution in European Psychiatric Association (EPA) member countries, considering indicators of socio-economic development, human and financial resources allocated in mental health (MH) as well as presence of a national branch of the Early Intervention in MH (IEPA). Contextually, we evaluated the duration of untreated psychosis (DUP) in relation to ED/EI service implementation.

METHODS

EPA section "Prevention of Mental Disorders" conducted the cross-sectional survey administering the 16-item questionnaire to the representatives of its National Psychiatric Associations (NPAs). The survey addressed the Service status and profile, national guidelines, education and policy, DUP and IEPA national branch status. The data were analysed in relation to the indices of economic parameters and MH resources.

RESULTS

Neither the national economic parameters, nor indices of MH financial resources were significantly associated with variables related to ED/EI implementation. However, more MH human resources per country were associated with shorter DUP. In comparison to countries without a national branch of IEPA, all of these with the branch had more MH human resources, ED/EI chapters in the national guidelines and services involving both adolescents and adults.

CONCLUSIONS

An unequal development of ED/EI services and related academic activities appears throughout Europe. The current results, besides providing a useful starting point to set the agenda for harmonizing ED/EI services, reveal that their implementation was more likely to be influenced by the IEPA membership status, rather than by country-specific financial and human resources allocated to MH.

Screening for psychosis risk among help-seeking adolescents: Application of the Italian version of the 16-item prodromal questionnaire (iPQ-16) in child and adolescent neuropsychiatry services

AIM

The 16-item Prodromal Questionnaire (PQ-16) is a versatile screen tool for routine screening of at-risk individuals. We wished to evaluate the psychometric properties of the Italian version of the PQ-16 (iPQ-16) in a sample of 72 help-seeking adolescents (age range 13-17 years) referred to child and adolescent neuropsychiatry services for diagnostic assessment.

METHODS

Participants who completed iPQ-16 were subsequently interviewed with the Comprehensive Assessment of At-Risk Mental States (CAARMS) to confirm the psychosis high risk state. We then examined the diagnostic accuracy (sensitivity, specificity, positive and negative predictive values [PPV e NPV]) and concurrent validity between iPQ-16 and CAARMS using Cronbach's alpha and Cohen's kappa. We also tested the validity of the adopted iPQ-16 cut-offs through Receiver Operating Characteristic (ROC) curves plotted against CAARMS diagnoses and the 1-year predictive validity of the iPQ-16.

RESULTS

Overall, the psychometric properties of the iPQ-16 were satisfactory. The iPQ-16 showed high internal consistency (Cronbach's alpha = .827) and acceptable diagnostic accuracy (77% sensitivity, 72% PPV) and concurrent validity (Cohen's k = 0.309). ROC analyses pointed to iPQ-16 total distress score of ≥10 as best cut-off.

CONCLUSION

The iPQ-16 is a reliable and valid instrument for routine screening of at-risk individuals in Italian neuropsychiatry services.

Clinical high risk for psychosis in childhood and adolescence: findings from the 2-year follow-up of the ReARMS project

The clinical significance and the prognostic value of clinical high risk (CHR) for psychosis, while substantially corroborated in adults, remains less firmly established in children and early adolescents. This follow-up study, developed within the Reggio Emilia At Risk Mental States project, is meant to contribute to the reduction of such lacuna, and has two main aims: (1) to characterize the clinical profile of help seekers [stratified in non-CHR, CHR and first episode psychosis (FEP)] referred to child-adolescent mental health services; and (2) to monitor the cumulative transition rate from CHR to FEP in adolescents at the follow-up of 12 and 24 months. 112 adolescents (aged 13-18 years) were assessed with the Comprehensive Assessment of At-Risk Mental States and the Schizophrenia Proneness Instrument, Child and Youth version. 51 subjects met CHR criteria (45.5% of the sample) and 33 subjects met FEP criteria (29.5%) at baseline. The criterial transition rate from CHR to FEP was 7% over 12 months and 13% over 24 months; higher rates of cumulative transition were detected when also functional transition (indexed by the consensual introduction of antipsychotic medication by the treating clinical staff) was considered. The identification of CHR for psychosis in help-seeking adolescents is feasible and clinically relevant. Studies conducted in real world, publicly funded components of the national health system, should take into consideration not only criterial, psychometric transition, but also functional equivalents of transition.

Implementing the Latvian Early Intervention Program (LAT-EIP) for Patients With Schizophrenia Spectrum First-Episode Psychosis: Study Protocol

Background: Patients with first-episode psychosis are mainly young people in the active phase of their social and professional lives, and psychosis is a serious disruption of normal life with high risk of disability. Integrated biopsychosocial early intervention treatment is crucial for patients with first-time psychosis episode. The purpose of this trial is to adapt the first early intervention program for patients with first-time non-affective psychosis in Latvia, and to investigate whether it is possible to integrate this kind of treatment approach in the frame of existing services and whether it provides better outcomes for patients than existing services. Design/Methods: The study has a nonrandomized controlled design in a real-life environment. Participants are all consecutive patients presenting in the psychiatric emergency room with first-time non-affective schizophrenia spectrum psychosis episode (ICD criteria F23, F20) from a catchment area of 262,541 inhabitants, with urban and rural regions. The Latvian Early Intervention Program is a 6-month program developed from existing treatment guidelines and recommendations and adapted to a low-resource environment, integrated in an existing outpatient unit. This study aimed to test the hypothesis that the patients who received intervention have milder symptoms, higher functioning, and better adherence to outpatient treatment. The study primary aims are: 1) to establish and examine in practice the adapted early intervention for patients with first schizophrenia spectrum psychosis; 2) compare clinical and functional outcomes (including occupation, housing, and social relationships) between intervention treatment and standard treatment; and 3) compare the number of rehospitalizations, adherence to outpatient treatment, and assigned disability. Secondary aims are: 1) to compare full recovery status in both treatment groups at 12 months follow-up and 2) to develop recommendations for establishing early intervention programs in limited resource settings. Discussion/Conclusions: Across the world, there is wide inequality in the availably and accessibility to early intervention treatment. This study will increase our knowledge in early intervention treatment approach and outcomes for patients with schizophrenia spectrum first psychosis episode in real-life working clinical practices. We hope to provide theoretical and practical aspects to develop strategies for early intervention service implementation in limited resource mental healthcare settings.

Sex and gender differences in schizophrenic psychoses-a critical review

Many sex and gender differences in schizophrenic psychoses have been reported, but few have been soundly replicated. A stable finding is the later age of onset in women compared to men. Gender differences in symptomatology, comorbidity, and neurocognition seem to reflect findings in the general population. There is increasing evidence for estrogens being psychoprotective in women and for hypothalamic-pituitary-gonadal dysfunction in both sexes.More methodologically sound, longitudinal, multi-domain, interdisciplinary research investigating both sex (biological) and gender (psychosocial) factors is required to better understand the different pathogenesis and etiologies of schizophrenic psychoses in women and men, thereby leading to better tailored treatments and improved outcomes.

Value of schizophrenia treatment II: Decision modelling for developing early detection and early intervention services in the Czech Republic

Background:

Positive findings on early detection and early intervention services have been consistently reported from many different countries. The aim of this study, conducted within the European Brain Council project “The Value of Treatment”, was to estimate costs and the potential cost- savings associated with adopting these services within the context of the Czech mental health care reform.

Methods:

Czech epidemiological data, probabilities derived from meta-analyses, and data on costs of mental health services in the Czech Republic were used to populate a decision analytical model. From the health care and societal perspectives, costs associated with health care services and productivity lost were taken into account. One-way sensitivity analyses were conducted to explore the uncertainty around the key parameters.

Results:

It was estimated that annual costs associated with care as usual for people with the first episode of psychosis were as high as 46 million Euro in the Czech Republic 2016. These annual costs could be reduced by 25% if ED services were adopted, 33% if EI services were adopted, and 40% if both, ED and EI services, were adopted in the country. Cost-savings would be generated due to decreased hospitalisations and better employment outcomes in people with psychoses.

Conclusions:

Adopting early detection and early intervention services in mental health systems based on psychiatric hospitals and with limited access to acute and community care could generate considerable cost- savings. Although the results of this modelling study needs to be taken with caution, early detection and early intervention services are recommended for multi-centre pilot testing accompanied by full economic evaluation in the region of Central and Eastern Europe.
