RESUMEN

BACKGROUND: Early identification of treatment non-response in first-episode psychosis (FEP) is essential to outcome. Despite indications that exposure to childhood trauma (CT) can have adverse effects on illness severity, its impact on treatment non-response and the interplay with other pre-treatment characteristics is sparsely investigated. We use a lack of clinical recovery as an early indicator of treatment resistance to investigate the relationship between CT and treatment resistance status at one-year follow-up and the potential mediation of this effect by other pre-treatment characteristics. METHODS: This prospective one-year follow-up study involved 141 participants recruited in their first year of treatment for a schizophrenia-spectrum disorder. We investigated clinical status, childhood trauma (CT), premorbid adjustment (PA), and duration of untreated psychosis (DUP) at baseline and clinical status at one-year follow-up. Ordinal regression analyses were conducted to investigate how PA and DUP affected the relationship between CT and one-year outcome in FEP. RESULTS: 45 % of the FEP sample reported moderate to severe CT, with significantly higher levels of CT in the early treatment resistant group compared to participants with full or partial early recovery. Ordinal regression analysis showed that CT was a significant predictor of being in a more severe outcome group (OR = 4.59). There was a partial mediation effect of PA and a full mediation effect of DUP on the effect of CT on outcome group membership. DISCUSSION: Our findings indicate that reducing treatment delays may mitigate the adverse effects of CT on clinical outcomes and support the inclusion of broad trauma assessment in FEP services.

RESUMEN

Engagement with a first episode-psychosis service (FES) reduces the risk of psychiatric hospitalization. However, the role of the duration of untreated psychosis (DUP) in impacting this outcome is disputed. This study aimed to examine whether DUP was an effect modifier of the post-FES reduction of risk of hospitalization, and to explore associations between patients' characteristics and hospitalization post-FES. Individuals aged 16-35 with recent onset (< 3 years) of non-affective psychosis, admitted to the Program for Specialized Treatment Early in Psychosis (STEP), a FES serving the Greater New Haven area, Connecticut, between 2014 and 2019 were included (N = 189). Medical records were queried from 2013 through 2020 for number and duration of psychiatric hospitalizations. Poisson regression models were used to estimate incidence rate ratios for hospitalization rates across all explanatory variables. Negative binomial regression was used to compare the length of stay (LOS) before vs after STEP enrollment. STEP admission was associated with a significant 90 % reduction in the frequency and duration of hospitalizations. This effect was moderated by DUP: with 30-day prolongations in components of DUP (supply, demand, and total) there was less reduction in hospitalizations and LOS after FES enrollment (p < .0001). Only DUP supply (time from first antipsychotic use to STEP admission) differentiated those who were hospitalized during the first year after STEP enrollment from those who were not (median: 35 vs. 15 weeks, p = .003). To fully harness the positive impact of FES on hospitalization, a detailed effort should be pursued to reduce all DUP components.

RESUMEN

Objective: To explore the relationship between the Duration of Untreated Psychosis (DUP) and long-term clinical outcome, cognitive and social function in patients with chronic schizophrenia (SCZ). Methods: A total of 248 subjects with chronic SCZ were enrolled in this study, including 156 in the short DUP group and 92 in the long DUP group. The Positive and Negative Symptoms Scale (PANSS), the Brief Negative Symptoms Scale (BNSS), the Global Assessment of Functioning (GAF) scale and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were used to assess all of the subjects. Results: The negative symptom scores (the PANSS and BNSS) of subjects with long DUP were significantly higher than that in subjects with short DUP. The scores of visual span and speech function in the short DUP group were significantly higher, indicative of decreasing cognitive function with time. In terms of social function, the short DUP group scored higher, with a statistically significant difference. Meanwhile, we found that the length of DUP was positively correlated with the negative symptom score of the PANSS, negatively correlated with visual span scores, and GAF scores. Conclusion: This study demonstrated that the DUP remained a significant association with negative symptom and cognition in long period of chronic SCZ.

RESUMEN

This invited commentary provides a conceptual history of modern early intervention services, briefly reviews the accomplishments of an international clinical and research community, and offers proposals for how such services might participate in the next generation of progress. In keeping with the theme of this column, we make the argument that such services should orient around bi-directional knowledge translation across basic, clinical and policy domains.

RESUMEN

Primary psychosis, which includes schizophrenia and other psychoses not caused by other psychic or physical conditions, has a strong impact worldwide in terms of disability, suffering and costs. Consequently, improvement of strategies to reduce the incidence and to improve the prognosis of this disorder is a current need. The purpose of this work is to review the current scientific literature on the main risk and protective factors of primary psychosis and to examine the main models of prevention, especially those related to the early detection of the onset. The conditions more strongly associated with primary psychosis are socio-demographic and economic factors such as male gender, birth in winter, ethnic minority, immigrant status, and difficult socio-economic conditions while the best-established preventive factors are elevated socio-economic status and an economic well-being. Risk and protective factors may be the targets for primordial, primary, and secondary preventive strategies. Acting on modifiable factors may reduce the incidence of the disorder or postpone its onset, while an early detection of the new cases enables a prompt treatment and a consequential better prognosis. According to this evidence, the study of the determinants of primary psychosis has a pivotal role in designing and promoting preventive policies aimed at reducing the burden of disability and suffering of the disorder.

RESUMEN

PURPOSE: To describe pathways to care, duration of untreated psychosis (DUP), and types of interventions provided to first-episode psychosis (FEP) patients by routine Italian mental health services over 5 years since the first service contact. METHODS: Naturalistic study conducted in Veneto, within the context of the Psychosis Incident Cohort Outcome Study (PICOS). A comprehensive set of measures was used, including schedules designed to collect information on referrals to psychiatric services and on psychological and pharmacological treatments at 1, 2, and 5 years since first service contact. RESULTS: Overall, 397 patients were assessed. Most engaged with services with the help of family members (47.4%) and through emergency routes (60.3%). Those referred by clinicians were more likely to access care in a non-emergency way. Mean DUP was 5.62 months (SD 11.8) and longer DUP was associated with poorer functioning at 2 and 5 years. Interventions provided over 5 years were mainly constituted by antipsychotic medications (95.4% at 1 year; 85.8% at 2 years; 80.6% at 5 years), whereas a lower percentage (69.1% at 1 year; 61.5% at 2 years; 44.9% at 5 years) also received some forms of psychological interventions, mainly consisting of unspecific support sessions. Other structured interventions, such as CBT or family interventions, were seldom provided at each time-point. CONCLUSIONS: Mental health services in Veneto seem effective in engaging FEP patients within a short time since illness onset. However, type of care provided does not meet quality standards recommended by treatment guidelines, especially regarding psychological interventions.

RESUMEN

INTRODUCTION: In recent years, the early detection and treatment of the first episode of schizophrenia (FES) has attracted worldwide attention. In Japan, psychiatric care has changed to an open and accessible framework over the past decade. Therefore, the duration of untreated psychosis (DUP) is thought to have been shortened. The purposes of this study were to investigate whether recent DUP periods are shorter than they were 10 years ago and whether the DUP at present differs among psychiatric facilities. We investigated the recent DUP at a psychiatric hospital and its satellite clinic. MATERIAL AND METHODS: We examined the differences in DUP, age, sex, referral pathway, living companions, social participation, and schooling history among 3 groups of FES patients: (i) a psychiatric hospital during 1999-2001 and (ii) during 2009-2011, and (iii) a psychiatric clinic during 2009-2011. RESULTS: The average DUP was 14.3 (SD = 17.5) months for the psychiatric hospital during 1999-2001, 16.0 (SD = 18.7) months for the psychiatric hospital during 2009-2011, and 24.4 (SD = 30.0) months for the psychiatric clinic during 2009-2011. No significant differences were found in the DUP for each facility and during this decade. Also, the differences in the DUP could not be attributed to factors such as living companions or social participation. DISCUSSION: Increases in the numbers of patients and psychiatric clinics have not led to the early detection of FES. To shorten the DUP in the future, closer cooperation among the medical field, the educational field, and the health and welfare will be needed.

RESUMEN

AIM: The duration of untreated psychosis (DUP) has been established as an independent and significant predictor of negative outcomes in first-episode psychosis samples. Whereas literature has supported the association between DUP and severity of positive and negative symptoms, surprisingly little research to date has explored specifically what types of positive and negative symptoms are most associated with DUP. METHODS: DUP, Scale for the Assessment of Positive Symptoms (SAPS) and Scale for the Assessment of Negative Symptoms (SANS) data were collected in 247 first-episode psychosis participants (mean age: 23.9 ± 4.8) between August 2008 and June 2013. RESULTS: DUP was significantly but modestly associated with the severity of hallucinations (ρ = 0.222; P = 0.001), delusions (r = 0.202; P = 0.003) and formal thought disorder (ρ = 0.138; P = 0.043) but was not associated with bizarre behaviour. DUP was significantly but modestly associated with SANS avolition-apathy (ρ = 0.164; P = 0.016) and anhedonia-asociality (r = 0.321; P < 0.001) subscales but was not associated with affective flattening or blunting, alogia or attention. CONCLUSIONS: DUP is a complex and multifaceted phenomenon that is associated with early-course illness development. In efforts to improve early intervention services, prognoses and outcomes, it is vital to understand both the factors that contribute to lengthy untreated psychosis as well as the illness characteristics that are impacted by untreated psychosis.

RESUMEN

Cognitive impairment is common in first-episode psychosis (FEP); however, the relationship between duration of untreated psychosis (DUP) and neurocognition remains controversial, and no studies have examined the relationship between DUP and social cognition. This study involved secondary data analysis of baseline data from a randomised controlled trial of supported employment; 122 out 146 young people with FEP met inclusion criteria for this study. Results showed that DUP was not associated with neurocognitive or social cognitive performance. Results do not provide support for the neurotoxicity hypothesis of psychosis.

RESUMEN

BACKGROUND: The neurotoxic hypothesis suggests that psychosis is toxic to the brain leading to clinical consequences. In this study, we hypothesized that a longer duration of untreated psychosis (DUP) in first episode schizophrenia (FES) patients is associated with poorer cognitive functioning, and that higher premorbid intelligence buffers against DUP-related cognitive impairment. METHOD: Eighty-one FES patients completed a neuropsychological battery, the Brief Assessment of Cognition in Schizophrenia (BACS). Composite scores of the BACS, which were normalized to a matched healthy control of seventy-three subjects, were used as an index of general cognition. A median split using the Wide Range Achievement Test-Reading Test scores was used to divide the patients into low versus high premorbid IQ groups. Hierarchical linear regression was performed to examine predictors of general cognition, including DUP. RESULTS: Longer DUP was found to be a significant predictor of poorer general cognition. In addition, DUP predicted general cognition in the low premorbid IQ group but not in the high premorbid IQ group. CONCLUSIONS: Our findings demonstrate that longer DUP in FES patients is associated with worse cognitive scores, and that this association is more pronounced in a subgroup of patients who have lower premorbid intelligence. Our results suggest the importance of earlier identification and management of patients with low premorbid IQ, given that their cognition may be more vulnerable to the toxicity of psychosis.

RESUMEN

AIM: The objective of the study was to explore the content of existing online resources available to information-seeking youth as psychotic symptoms first emerge and determine how these resources may influence initiation of care. METHODS: Using 18 hypothetical search terms, developed by the Early Treatment Programme (ETP) staff, we searched three of the most popular websites used by the youth (Google, Facebook and Twitter) and extracted the first five hits from each. Sites were categorized into those that encouraged help seeking, those that potentially contribute to treatment delay, those with an undetermined impact and those that were unrelated to treatment. RESULTS: An alarmingly few of the first five hits from the top three online resources encourage potentially psychotic youth to seek professional evaluation. The majority of our search results yielded unmonitored chat forums that lacked a unified message. The remainder promoted stigma, normalized potentially psychotic experiences or were completely unrelated to mental health. CONCLUSION: We must develop innovative, easy-to-access and youth-focused online and social media experiences that encourage symptomatic youth to seek care.

RESUMEN

BACKGROUND: The mode of onset and the course of schizophrenia illness exhibit substantial individual variations. Previous studies have pointed out that the mode of onset affects the duration of untreated psychosis (DUP) and clinical outcomes, such as cognitive and social functioning. This study attempted to clarify the association between the DUP and clinical features, taking the different modes of onset into consideration, in a prospective longitudinal study examining patients with first-episode schizophrenia. METHODS: This study was conducted in six areas of Japan. Patients with first-episode schizophrenia were followed for over 18 months. Cognitive function, psychopathology, and social functioning were assessed at baseline and at 6, 12, and 18-month follow-up points. RESULTS: We identified 168 patients and sufficient information was available to determine the DUP and the mode of onset for 156 patients (92.9%): 79 had an acute onset, and 77 had an insidious onset. The DUP was significantly associated with quality of life (QOL), social functioning, and cognitive function at most of the follow-up points in the insidious-onset group. The DUP and negative symptoms at baseline were significant predictors of cognitive function at the 18-month follow-up in the insidious-onset group. CONCLUSIONS: The present results further support the hypothesis that the DUP affects QOL, social functioning, and cognitive function over the course of illness, especially in patients with an insidious onset. Effective strategies for detecting and caring for individuals with insidious onset early during the course of schizophrenia will be essential for achieving a full patient recovery.

RESUMEN

Although the family has an important role in the early detection and intervention of first-episode psychosis (FEP), there are few findings reporting associations between family strengths and early treatment-seeking experiences. This study aimed to investigate, within the framework of the resiliency model of family stress, adjustment, and adaptation, the association between family coping strategies, resource management factors and duration of untreated psychosis (DUP) in Iranian families with one adult child with FEP. Hundred and seven individuals referred to three medical centers in Tehran and diagnosed with FEP participated in this study. Caregiver-perceived DUP was measured via semi-structured interviews administered to primary caregivers. They also completed two questionnaires regarding family resources of stress management and family coping strategies. Data analysis indicated that the Family Inventory of Resources of Management (FIRM) total scale score did not significantly explain the variance of caregiver-perceived DUP, but one of the FIRM subscales, the Extended Family Social Support, and the Family Crisis-Oriented Personal Evaluation scale (F-COPES) total score and one its subscales, the Acquiring Social Support, explained a significant amount of the variance of caregiver-perceived DUP. The results suggest that higher family resiliency, especially social support, facilitates the family's appropriate adaptive reaction (i.e., treatment-seeking), with the consequent decrease of DUP.

RESUMEN

Longer duration of untreated psychosis (DUP) in adult patients with first-episode psychosis (FEP) has been associated with poor clinical and social outcomes. We aimed to estimate the influence of DUP on outcome at 2-year follow-up in subjects with an early-onset (less than 18 years of age) FEP of less than 6 months' duration. A total of 80 subjects (31.3% females, mean age 16.0±1.8 years) were enrolled in the study. The influence of DUP on outcome was estimated using multiple regression models (two linear models for influence of DUP on the C-GAF at 2 years and C-GAF change through the follow-up period, and a logistic model for influence of DUP on 41 PANSS remission at 2 years in schizophrenia patients (n=47)). Mean DUP was 65.3±54.7 days. Median DUP was 49.5 days. For the whole sample (n=80), DUP was the only variable significantly related to C-GAF score at 2-year follow-up (Beta=-0.13, p<0.01), while DUP and premorbid adjustment (Beta=-0.01, p<0.01; and Beta=-0.09, p=0.04, respectively) were the only variables significantly related to C-GAF change. In schizophrenia patients, DUP predicted both C-GAF score at 2 years and C-GAF change, while in patients with affective psychosis (n=22), DUP was unrelated to outcome. Lower baseline C-GAF score (OR=0.91, p<0.01) and shorter DUP (OR=0.98, p=<0.01) were the only variables that significantly predicted clinical remission in schizophrenia patients. In conclusion, longer DUP was associated with lower C-GAF at 2 years, less increase in C-GAF, and lower rates of clinical remission in early-onset FEP. Our findings support the importance of early detection programs, which help shorten DUP.

RESUMEN

BACKGROUND: Duration of untreated psychosis (DUP) has been shown to be associated with both poor short-term and long-term outcomes in schizophrenia. Even so, few studies have used functional neuroimaging to investigate DUP in schizophrenia. In the present study, we used near-infrared spectroscopy (NIRS) to investigate the influence of DUP on brain functions during a verbal fluency test (VFT) in patients with schizophrenia. METHODS: A total of 62 patients with schizophrenia were included. They were categorized into either short treatment (≤6months, n=33) or long treatment (>6months, n=29) groups based on their duration of treatment. Hemodynamic changes over the frontotemporal regions during a VFT were measured using multi-channel NIRS. We examined the associations between DUP and hemodynamic changes in each group to explore if there were different effects of DUP on brain cortical activity at different treatment durations. RESULTS: In the long treatment group, we found significant associations between a longer DUP and decreased cortical activity approximately at the left inferior frontal gyrus, left middle frontal gyrus, left postcentral gyrus, right precentral gyrus, bilateral superior temporal gyrus, and bilateral middle temporal gyrus, whereas no associations between DUP and brain cortical activity were observed in the short treatment group. CONCLUSIONS: Our results indicated that longer DUP may be associated with decreased level of cortical activities over the frontotemporal regions in the long-term. Early detection and intervention of psychosis that shortens DUP might help to improve the long-term outcomes in patients with schizophrenia.

RESUMEN

One of the main goals in treatment planning of psychiatric disorders is early diagnosis of patients in the early psychosis period so that duration of untreated psychosis (DUP) is decreased and the treatment response and outcome is improved. The aim of this study was to investigate the DUP of psychosis and factors affecting it. In this cross-sectional study, 80 patients from the psychiatric clinic of Fatemi hospital in Ardabil and Razi hospital in Tabriz who were in the first episode of psychosis completed a questionnaire. The data were analysed by SPSS statistical software. In this study, the mean DUP measured from the appearance of the first symptoms of psychosis were 261.3 ± 110.8 and 212.5 ± 143.5 days for patients referring to Razi and Fatemi hospital, respectively. About 65% of the patients in Fatemi hospital and 32.5% of them in Razi hospital considered visiting a psychiatrist as hard and very hard. The DUP mean here was found to be higher as compared with that of the developed countries. The following factors were found to be playing a role in making DUP longer: lower education, implausible beliefs and culturally rooted social stigma status of visiting a psychiatrist.

RESUMEN

Objective: Mental health services in Malaysia often face competition from traditional healers especially among patients with psychosis. The objective of the study is to determine whether patients who sought help earlier from traditional healers had longer duration of untreated psychosis (DUP), and more adverse experiences in pathways to psychiatric care. Methods: This is a hospital-based cross-sectional study of 50 inpatients with first-episode psychosis in Hospital Kuala Lumpur. Structured Clinical Interview for DSM-IV (Diagnostic and statistical manual, 4th edition) Clinical Version for Axis I Disorders (SCID-CV) was used for establishing diagnosis. Onset of psychosis was defined as any one positive symptom with a score of >3 on the Positive and Negative Syndrome Scale (PANSS). Socio-demographic data, information on pathways and treatment delaying factors were determined through face-to-face interview and semi-structured questionnaire. Results: Fifty-four percent of the patients had at least one contact with traditional healers prior to consulting psychiatric service, and it was the most popular first point of non-psychiatric help-seeking contact (48%). Contact with traditional healers was not associated with age, gender, ethnic, education level, longer DUP or treatment delay, and admissions with violent behaviour or police assistance. Of those who had sought help from traditional healers, one third were recommended by at least one of their traditional healers to seek medical help. Conclusion: Consultation involving traditional healers was a popular choice, and not associated with treatment delay. Traditional healers in an urban setting may be potential collaborators in managing patients with first-episode psychosis. Future research should explore the frontiers of such collaborative work.
