Short-term exposure to antipsychotics has proven to be beneficial. However, naturalistic studies are lacking regarding the long-term use of antipsychotics. This study aimed to investigate changes in use of antipsychotics over 20 years after a first-episode schizophrenia.

This study is part of the Danish OPUS trial (1998–2000), including 496 participants with first-episode schizophrenia. Participants were reassessed four times over 20 years. The main outcomes were days on medication, redeemed prescriptions of clozapine, psychiatric hospitalizations, and employment.

At the 20-year follow-up, an attrition of 71% was detected. In total, 143 out of 496 participated, with 36% (n = 51) in remission-of-psychotic-symptoms-off-medication. The lowest number of days on medication (mean [s.d.], 339 [538] days) was observed in this group over 20 years. Register data on redeemed antipsychotics were available for all trial participants (n = 416). Individuals in treatment with antipsychotics (n = 120) at the 20-year follow-up had spent significantly more days in treatment (5405 [1857] v. 1434 [1819] mean days, p = 0.00) and more had ever redeemed a prescription of clozapine (25% v. 7.8%, p = 0.00) than individuals who had discontinued antipsychotics (n = 296). Further, discontinuers had significantly higher employment at the 20-year follow-up (28.4% v. 12.5%, p = 0.00).

In a cohort of individuals with first-episode schizophrenia, 36% were in remission-of-psychotic-symptoms-off-medication. However, high attrition was detected, potentially affecting study results by inflating results from individuals with favorable outcomes. From register data, free from attrition, approximately 30% were in treatment with antipsychotics, and 70% had discontinued antipsychotics. Individuals in treatment had the least favorable outcomes, implying greater illness severity.

The duration of untreated psychosis (DUP) continues to be a global priority. Early intervention services were established to reduce treatment delays but have had limited impact. This systematic review examines barriers and facilitators to seeking access to these services, to identify targets for service level change.

We conducted a systematic review of relevant databases (PsychINFO, MEDLINE, CINAHL, and PsychARTICLES) using pre-defined search terms for psychosis, early intervention, and barriers and facilitators. Given the majority of qualitative studies, a thematic synthesis rather than meta-analysis was indicated.

The search yielded 10 studies. Mental health stigma and discrimination predict DUP, compounded by structural barriers which limit the impact of early intervention services on timely access to recommended treatments. Synthesis of the qualitative studies generated three themes: knowledge, relationships, and stigma. Lack of knowledge, absence of supportive relationships (social and professional), and self-stigma constitute significant barriers to seeking access to early intervention services.

This is the first review of the barriers and facilitators to seeking access to early intervention services. The findings highlight public health and secondary care service targets to expedite access to recommended treatments and thereby reduce the DUP.

Studies have consistently found that many individuals with psychosis experience significant delays before receiving treatment. DUP refers to the period between the emergence of psychotic symptoms and the initiation of appropriate clinical treatment.

To review current knowledge on the best approach for patients with schizophrenia (SCZ) and prolonged DUP.

Non-systematic review of literature through search on PubMed database, following the terms “DUP and treatment” and “impact of longer DUP”. Two clinical cases are described.

The clinical cases describe patients with SCZ with DUPs older than 10 years, in whom we could not achieve complete clinical remission after several therapeutic trials and whose prognosis was admitted as reserved. Longer DUP is an independent predictor of poorer outcome in SCZ, including the poor response to treatment and difficulty in achieving remission, predicting treatment resistance. Identifying treatment-resistant patients is crucial due to the importance of initiating clozapine as early as possible since the chances of responding are higher.

DUP is a key prognostic variable in psychosis, revealing the significance of early treatment. Patients with long DUP should be regarded as at high risk of poor recovery. The detection of these patients enables clinicians to avoid unnecessary exposure to ineffective treatments while effective interventions are delayed. However, in view of adverse side effects of clozapine, future studies need to examine relevant predictors to detect accurately non-responders. We also suggest further studies to understand if there is correspondence between DUP and different stages of the disease that justify these results.

As Ireland confronts the many challenges of broadening the introduction of early intervention services (EIS) for first episode psychosis (FEP) as national policy, this article describes Carepath for Overcoming Psychosis Early (COPE), the EIS of Cavan–Monaghan Mental Health Service, and presents prospective research findings during its first 5 years of operation.

COPE was launched as a rural EIS with an embedded research protocol in early 2012, following an education programme for general practitioners (GPs). Here, operational activities are documented and research findings presented through to late 2016.

During this period, 115 instances of FEP were incepted into COPE, 70.4% via their GP and 29.6% via the Emergency Department. The annual rate of inception was 24.8/100,000 of population aged > 15 years and was 2.1-fold more common among men than women. Mean duration of untreated psychosis was 5.7 months and median time from first psychotic presentation to initiation of antipsychotic treatment was zero days. Assessments of psychopathology, neuropsychology, neurology, premorbid functioning, quality of life, insight, and functionality compared across 10 DSM-IV psychotic diagnoses made at six months following presentation indicated minimal differences between them, other than more prominent negative symptoms in schizophrenia and more prominent mania in bipolar disorder.

COPE illustrates the actuality of introducing and the challenges of operating a rural EIS for FEP. Prospective follow-up studies of the 5-year COPE cohort should inform on the effectiveness of this EIS model in relation to long-term outcome in psychotic illness across what appear to be arbitrary diagnostic boundaries at FEP.

To create an image of therapeutic options available for the first episode psychsis and the way these options influence the evolution of patients.

The present study is part of a larger follow-up study on a number of 121 patients with a diagnostic of first episode psychosis admitted in the Timisoara Psychiatric Clinic and The Day Clinic in the Timisoara Mental Health Center between 2003-2006 and prospectively monitored from the moment of their first contact with psychiatric services.

The average calculated duration of prodrome period and average Duration of Untreated Psychosis (DUP) are similar to the results indicated by most other studies. The results of statistical tests show that: the longest the prodrome, the worse the improvement of illness during course; a longer prodrome is correlated with a higher number of relapses during the patient's illness course and a longer Duration of Untreated Psychosis is likely to lead to an increased severity of illness. Patients’ adherence to treatment is influenced both by the traits of the first psychotic episode and the way the patients perceive the side effects and the general utility of the administered medication.

Psychiatrists have to dedicate more time and interest to establishing a therapeutic alliance with their patients with first episode psychosis; an individualized strategy is required to establish the adequate means and ways of intervention before initiating any type of therapy.

The duration of untreated psychosis (DUP) has been widely studied. However, for individuals with attenuated psychosis syndrome (APS), it is unclear whether the duration of untreated prodromal symptoms (DUPrS) also has a negative effect on the progression of psychosis. Our aim was to identify demographic and clinical factors contributing to the DUPrS in a large sample of individuals with APS, and to evaluate the association between DUPrS and the conversion to psychosis.

A sample of 391 individuals with APS, who were identified through a structured interview for prodromal syndromes, were included in this study, of whom a total of 334 patients had completed at least a 1-year clinical follow-up. A total of 57 individuals had converted to psychosis.

The average DUPrS was 4.8 months for the whole sample. Individuals with a longer DUPrS were likely to be men, non-local residents, with abnormal thought symptoms, a higher severity level of negative symptoms, the lower severity level of general symptoms, and lower level of general function before the onset of attenuated positive symptoms. A DUPrS of less than 2 months, or more than 6 months, lowered the risk for conversion to psychosis.

Our data suggested that the association between the DUPrS and outcome in individuals with APS were likely to be different, which is either long or short DUPrS was not related to future psychosis onset. Individuals with APS were more likely to have a group of features associated with a longer DUPrS.

Duration of untreated psychosis (DUP) is an important measure of access to care as it predicts prognosis and treatment outcomes. Little is known about potential socioeconomic inequalities in DUP. The aim of this study was to investigate inequalities in DUP associated with socioeconomic deprivation in a national cohort in England.

We analysed a cohort of 887 patients with a first-episode in psychosis using the administrative Mental Health Services Dataset in England for 2012/13-2014/15. We used a Generalised Linear Model to account for non-linearity in DUP and looked at inequalities across the whole distribution of DUP using quantile regression.

The median DUP was 22 days (mean = 74 days) with considerable variations between and within the 31 hospital providers. We found evidence of significant inequalities regarding the level of socioeconomic deprivation. Patients living in the second, third and fourth deprived neighbourhood quintiles faced a 36, 24 and 31 day longer DUP than patients from the least deprived neighbourhoods. Inequalities were more prevalent in higher quantiles of the DUP distribution. Unemployment prolonged DUP by 40 days. Having been in contact with mental health care services prior to the psychosis start significantly reduced the DUP by up to 53 days.

Socioeconomic deprivation is an important factor in explaining inequalities in DUP. Policies to improve equitable access to care should particularly focus on preventing very long delays in treatment and target unemployed patients as well as people that have not been in contact with any mental health professional in the past.

The incidence of psychotic disorders varies between geographical areas and it has been hypothesized that neighbourhood-level factors may influence this variation. It is also plausible that the duration of untreated psychosis (DUP) is associated with neighbourhood characteristics. The aims of this study were to determine whether the incidence of first-episode psychosis (FEP) and the DUP are associated with the level of social deprivation, fragmentation, social capital and population density.

All individuals with a FEP from a geographical defined catchment area over a 5-year period were included. Age-standardized incidence rates were calculated for each neighbourhood factor.

A total of 292 cases of FEP were included in the study and 45% had a diagnosis of a schizophrenia-spectrum disorder. The age standardized incidence rate of FEP in the most deprived area was 72.4 [95% confidence interval (CI) 26.4–162.7] per 100 000 person-years compared with 21.5 (95% CI 17.6–26.0) per 100 000 person-years in the most affluent areas. This represents a 3.4-fold increase in FEP incidence in the most deprived areas. The incidence of FEP was also increased in neighbourhoods that were more socially fragmented [incidence rate ratio (IRR) = 2.40, 95% CI 1.05–5.51, p = 0.04] and there was a trend for the incidence to be increased in neighbourhoods with lower social capital (IRR = 1.43, 95% CI 0.99–2.06, p = 0.05). The median DUP was 4 months and was higher in more socially fragmented neighbourhoods.

The incidence of psychotic disorders is related to neighbourhood factors and it may be useful to consider neighbourhood factors when allocating resources for early intervention services.

The association between the duration of untreated psychosis (DUP) and outcome of schizophrenia may be confounded by other factors such as poor pre-morbid adjustment. The aim of the present study was to examine the independent contributions of DUP and of pre-morbid adjustment to the clinical and social outcomes of schizophrenia.

A longitudinal, prospective, 2-year follow-up study of 423 patients with first-episode schizophrenia-spectrum psychosis was conducted. Patients were comprehensively assessed at entry, 1-year and 2-year follow-up. At entry, DUP was measured by IRAOS (an instrument for the assessment of onset and early course of schizophrenia) and pre-morbid adjustment was measured by the Pre-morbid Adjustment Scale (PAS) as ‘pre-morbid social adaptation’ and ‘pre-morbid school adaptation’. Outcome measures included the Scale for the Assessment of Positive Symptoms (SAPS), the Scale for the Assessment of Negative Symptoms (SANS), the Social Network Schedule and social information. Multiple linear regression models were used for data analysis.

The median DUP was 48 weeks, which is long compared to other studies. Longer DUP was independently associated with more psychotic symptoms at entry, 1-year and 2-year follow-up. Poorer pre-morbid social adaptation was independently associated with more negative symptoms and smaller social network at entry and 1-year follow-up. Poorer pre-morbid school adaptation was independently associated with poor vocational outcome at 1-year and 2-year follow-up.

Longer DUP is associated with poorer 2-year outcome of psychosis in schizophrenia-spectrum disorders, when pre-morbid functioning and other prognostic factors are controlled for. Impaired pre-morbid development is independently associated with more negative symptoms and poorer social outcome.
