The role of treatment delay in predicting 5-year outcomes in an early intervention program

Factors associated with recovery during schizophrenia and related disorders: A review of meta-analysis

BACKGROUND

The spectrum of schizophrenia disorders (SSD) is a severe mental disorder. It is one of the main medical causes of disability that generates high health and social costs.

OBJECTIVE

To analyze the factors associated with clinical recovery (CR) (symptomatic remission-SR and functional recovery-FR) and personal recovery (PR) in people diagnosed with SSD.

METHODS

14 meta-analyses focused on recovery were reviewed following the PRISMA model statements. 95 % of CI was established.

RESULTS

Shorter Duration of Untreated Psychosis (Zr = 0.24, [0.17, 0.30]) and total Duration of Untreated Illness (Zr = 0.34, [0.20, 0.48]) were related to greater SR and general functioning, respectively. Resilience was the variable with the greatest effect on FR (Zr = 0.67, [0.63, 0.71]). Premorbid adjustment (Zr = 0.34, [0.18, 0.49]) and physical intervention (Zr = 0.71, [0.55, 0.86]) had the greatest effect on occupational and social functioning, respectively. Less severe affective symptoms were related to greater PR (Zr = 0.46, [0.42, 0.50]). There are differences between affective SR and the other types of SR (Zr(SR-A - SR-) = 0.13, Qb = 6.51, p = 0.011), (Zr(SR-A - SR+) = 0.20, Qb = 8.52, p = 0.004), (Zr(SR-A - SR) = 0.18, Qb = 19.29, p = 0.0001). In all, resilience was associated with greater recovery (Zr = 0.67, [0.53, 0.80]), with the global effect being greater on PR than on CR (Zr(PR-CR) = 0.07, Qb = 3.45, p = 0.05).

CONCLUSIONS

Resilience was the variable most strongly associated with recovery. Symptomatic or functional improvement obtained less statistical weight.

The iHOPE-20 study: Relationships between and prospective predictors of remission, clinical recovery, personal recovery and resilience 20 years on from a first episode psychosis

OBJECTIVE

Knowledge of outcome in psychotic illness is limited by the paucity of very long-term epidemiologically representative studies of incidence first episode psychosis (FEP) cohorts that measure and compare outcomes reflecting modern clinical practice, mental health policy and research agendas. Our study aimed to address this gap.

METHOD

iHOPE-20 is a prospective 20-year follow-up study of a FEP incidence cohort (N = 171) conducted between 2014 and 2017 in Ireland. Data from previous studies and medical records were used to recruit cohort members. We assessed remission, clinical recovery, personal recovery and resilience at 20 years; explored the relationships between these outcomes and examined the predictive value of baseline characteristics in determining them.

RESULTS

At follow-up, 20 out of 171 cohort members (11.70%) were deceased. We assessed 80 out of 151 alive cohort members (53% recruitment rate); 65% were in remission; 35.2% were in Full Functional Recovery and 53.7% confirmed they were fully recovered according to their personal definition of recovery. A complex array of relationships between outcomes was found. Outcomes were better for people who had a short duration of untreated psychosis, displayed higher premorbid social adjustment (between the ages of 5-11) and at baseline, were older, not living alone, in full-time employment, given a non-affective diagnosis, and had lower Global Assessment of Functioning scores.

CONCLUSION

Among participants, full remission of psychotic symptoms and personally defined recovery was not just possible but likely in the very long term. However, attaining positive functional outcomes and building resilience in FEP remain key challenges for mental health services.

Stability of outcomes after 5 years of treatment in an early intervention programme

AIM

It has been hypothesized that the first 5 years are critical in determining long-term recovery from psychotic disorders. We examine stability in recovery indices after 5 years for 56 patients treated in an early intervention programme for psychosis.

METHODS

Assessments of symptom remission and functional recovery were carried out 5 and 10 years after initiation of treatment.

RESULTS

Although overall rates of recovery were comparable at both times, there were significant changes for individuals reflecting both improvement and deterioration.

CONCLUSIONS

Evidence concerning the critical period hypothesis should examine stability in individuals rather than relying on cumulative indices.

Untreated illness and recovery in clients of an early psychosis intervention program: a 10-year prospective cohort study

PURPOSE

To investigate whether duration of untreated psychosis (DUP) and duration of untreated illness (DUI) are associated with measures of both subjective and objective recovery 10 years after a first episode of psychosis.

METHODS

A cohort of 65 clients from an early psychosis intervention program completed a battery of outcome measures 10 years following initial treatment for first-episode psychosis (FEP). The outcomes of interest were self-perceived recovery scores (Maryland Assessment of Recovery in People with Serious Mental Illness Scale) and occupational activity, defined as engagement in work and/or school on a full/part-time basis. Multiple linear and logistic regression analyses were used to estimate the associations between DUP and DUI with each measure of recovery, adjusting for potential confounding factors.

RESULTS

We did not find a statistically significant association between DUP and either occupational activity (OR = 1.26, 95% CI 0.81-1.95) or self-perceived recovery score (β = - 0.73, 95% CI - 2.42 to 0.97). However, we found a significant negative association between DUI and self-perceived recovery score (β = - 0.52, 95% CI - 0.87 to - 0.16).

CONCLUSIONS

Our findings suggest that DUI may have a stronger influence than DUP on recovery from FEP at 10-year follow-up. This suggests the potential value in targeted interventions for people with a long DUI to increase the likelihood of achieving recovery after the first episode of psychosis.

Men and women with psychosis and the impact of illness-duration on sex-differences: The second Australian national survey of psychosis

We aimed to examine and compare sex-differences in people receiving treatment for psychotic illnesses in community settings, based on long or short duration of illness; expecting association between longer illness-duration and worse outcomes in women and men. Clinical, demographic and service-use data from the Survey of High Impact Psychosis were analysed by sex and duration of illness (≤5 years; ≥6 years), using independent t-tests, chi-square tests, one-way ANOVA, and Cramer's V. Of the 1825 participants, 47% had schizophrenia, 17.5% bipolar and 16.1% schizo-affective disorders. More women than men had undertaken post-school education, maintained relationships, and been living in their own homes. Women with a shorter-illness-duration showed social functioning equivalent to non-ill women in the general population. Men tended to have an early illness onset, show premorbid dysfunction, be single, show severe disability, and to use illicit substances. Men with a longer-illness-duration were very socially disadvantaged and isolated, often experiencing homelessness and substance use. Men with a short-illness-duration were most likely to be in paid employment, but two-thirds earned less than $AUD500 per fortnight. Men with longer-illness-duration showed most disability, socially and globally. Interventions should be guided by diagnosis, but also by a person's sex and duration of illness.

Patterns of illness and care over the 5 years following onset of psychosis in different ethnic groups; the GAP-5 study

PURPOSE

Previous research has not provided us with a comprehensive picture of the longitudinal course of psychotic disorders in Black people living in Europe. We sought to investigate clinical outcomes and pattern of care in Black African and Black Caribbean groups compared with White British patients during the first 5 years after first contact with mental health services for psychosis.

METHODS

245 FEP cases aged 18-65 who presented to psychiatric services in 2005-2010 in South London (UK). Using the electronic psychiatric clinical notes in the South London and Maudsley NHS Foundation Trust (SLaM), extensive information was collected on three domains-clinical, social, and service use.

RESULTS

During the 5-year follow-up (mean = 5.1 years, s.d. = 2.4; 1251 person years) after first contact with mental health services, a higher proportion of Black African and Black Caribbean ethnicity had compulsory re-admissions (χ 2 = 17.34, p = 0.002) and instances of police involvement during an admission to a psychiatric unit (χ 2 = 22.82, p < 0.001) compared with White British ethnic group. Patients of Black African and Black Caribbean ethnicity did not differ from the ethnic group in overall functional disability and illness severity, or frequency of remission or recovery during the follow-up period. However, patients of Black ethnicity become increasing socially excluded as their illness progress.

CONCLUSIONS

The longitudinal trajectory of psychosis in patients of Black ethnicity did not show greater clinical or functional deterioration than white patients. However, their course remains characterised by more compulsion, and longer periods of admission.

The course of negative symptoms over the first five years of treatment: Data from an early intervention program for psychosis

BACKGROUND

Cross-sectional studies suggest that negative symptoms are constituted by separable domains of reduced expressiveness and reduced motivation, but there is little data on the longitudinal course of these symptoms. We examined evidence for differences in the course and correlates of these two domains in a prospective study of patients presenting with a first episode of psychosis.

METHODS

Of 132 patients who were followed up for five years, it was possible to monitor reduced expressiveness and motivation on a weekly basis for 127. Information on treatment delay, premorbid adjustment, intellectual functioning, anxiety, depression and psychosocial functioning were also collected.

RESULTS

Over the five year follow-up, symptoms of reduced motivation occurred in 95.3% of patients and reduced expressiveness in 68.5%; and deficits in motivation were more likely to be unremitting (15.7%) than expressive deficits (5.5%). There were differences in the correlates of the proportion of time each patient experienced symptoms of each domain. Depression, weeks of full time occupation and weeks on a disability pension were associated with both domains. Anxiety was associated only with diminished motivation. Lower performance IQ; extrapyramidal symptoms (EPS) and dysrhythmic EEG were associated only with proportion of time showing reduced expressiveness.

CONCLUSIONS

The prospective data support previous cross-sectional findings that, while these domains of negative symptoms are correlated, they do show differences in prevalence over time and in their correlates.

Duration of unspecific prodromal and clinical high risk states, and early help-seeking in first-admission psychosis patients

PURPOSE

Prevention of psychosis requires both presence of clinical high risk (CHR) criteria and early help-seeking. Previous retrospective studies of the duration of untreated illness (i.e. prodrome plus psychosis) did not distinguish between prodromal states with and without CHR symptoms. Therefore, we examined the occurrence of CHR symptoms and first help-seeking, thereby considering effects of age at illness-onset.

METHODS

Adult patients first admitted for psychosis (n = 126) were retrospectively assessed for early course of illness and characteristics of first help-seeking.

RESULTS

One-hundred and nine patients reported a prodrome, 58 with CHR symptoms. In patients with an early illness-onset before age 18 (n = 45), duration of both illness and psychosis were elongated, and CHR symptoms more frequent (68.9 vs. 33.3 %) compared to those with adult illness-onset. Only 29 patients reported help-seeking in the prodrome; this was mainly self-initiated, especially in patients with an early illness-onset. After the onset of first psychotic symptoms, help-seeking was mainly initiated by others. State- and age-independently, mental health professionals were the main first point-of-call (54.0 %).

CONCLUSIONS

Adult first-admission psychosis patients with an early, insidious onset of symptoms before age 18 were more likely to recall CHR symptoms as part of their prodrome. According to current psychosis-risk criteria, these CHR symptoms, in principle, would have allowed the early detection of psychosis. Furthermore, compared to patients with an adult illness-onset, patients with an early illness-onset were also more likely to seek help on their own account. Thus, future awareness strategies to improve CHR detection might be primarily related to young persons and self-perceived subtle symptoms.

Glutamatergic metabolite correlations with neuropsychological tests in first episode schizophrenia

Increased glutamatergic metabolites have been found in first episode schizophrenia. Although abnormal neuropsychological functioning has been demonstrated to be a core feature of schizophrenia, no studies have examined glutamatergic metabolites and neuropsychological function in drug-naïve patients. The present study addressed whether higher levels of glutamatergic metabolites would be associated with poorer neuropsychological performance and social functioning in first episode patients. Glutamatergic concentration estimates were obtained from the left anterior cingulate cortex (ACC) and thalamus at baseline and 10 months after treatment in 16 patients with psychosis using 4.0 T (1)H magnetic resonance spectroscopy. A neuropsychological test battery was administered at baseline and 1 year. In the ACC, baseline glutamine was associated with performance on the Paced Auditory Serial Addition Task (PASAT). Glutamate at 10 months was associated with Wisconsin Card Sorting Test (WCST) errors and Trail-Making Test-B duration. Glutamine at 10 months was positively associated with WCST errors and negatively associated with WCST categories completed. In the thalamus, baseline glutamine was negatively associated with performance on the PASAT. Thalamic glutamate at baseline showed a trend towards a negative association with social functioning at 5 years. Glutamatergic metabolites were associated with neuropsychological test deficits and impaired social functioning at 5-year follow-up in patients with first episode psychosis, findings suggestive of an association between glutamatergic alterations on neurotoxicity early in the course of schizophrenia.

A controlled evaluation of a targeted early case detection intervention for reducing delay in treatment of first episode psychosis

PURPOSE

Interventions aimed at influencing specific pathways to care may reduce the duration of untreated psychosis (DUP). The purpose of this study was to reduce delay in referral to an early intervention service following first contact for help seeking for psychosis in a defined urban catchment area.

METHODS

Using a historical control design, we conducted a targeted intervention comprised of intensive training and education regarding first onset of psychosis and benefits of early intervention with all potential points of contact in pathways to care in a defined catchment area of a specialized early intervention (EI) service. Data collected on different components of DUP [help seeking (H-DUP) and referral (R-DUP)] and demographic and clinical characteristics on patients seeking treatment of first episode of a psychotic (FEP) disorder accepted in the EI service for 3 years before and 3 years after the intervention were contrasted. No other systemic changes occurred in this catchment area during this period.

RESULTS

There was a significant increase in the number of cases of FEP referred to the EI service post-intervention from hospitals other than the parent institute, in the proportion with a diagnosis of affective psychosis and proportion of patients from a lower socioeconomic status (SES). Although largest proportion of patients continued to make their first contact with community services, the latter failed to refer cases of psychosis to the EI service despite making a large number of mostly non-cases (for psychosis). The intervention had no direct effect on total DUP, R-DUP or H-DUP. After controlling for diagnosis and SES, post-intervention, R-DUP remained significantly lower for patients making first contact with the emergency service of the parent institute.

CONCLUSIONS

The intervention failed to reduce R-DUP for patients making contact with or referred from community services and most patients still used hospital resources to enter treatment at the EI service.

Reappraising the long-term course and outcome of psychotic disorders: the AESOP-10 study

BACKGROUND

Studies of the long-term course and outcome of psychoses tend to focus on cohorts of prevalent cases. Such studies bias samples towards those with poor outcomes, which may distort our understanding of prognosis. Long-term follow-up studies of epidemiologically robust first-episode samples are rare.

METHOD

AESOP-10 is a 10-year follow-up study of 557 individuals with a first episode of psychosis initially identified in two areas in the UK (South East London and Nottingham). Detailed information was collated on course and outcome in three domains (clinical, social and service use) from case records, informants and follow-up interviews.

RESULTS

At follow-up, of 532 incident cases identified, at baseline 37 (7%) had died, 29 (6%) had emigrated and eight (2%) were excluded. Of the remaining 458, 412 (90%) were traced and some information on follow-up was collated for 387 (85%). Most cases (265, 77%) experienced at least one period of sustained remission; at follow-up, 141 (46%) had been symptom free for at least 2 years. A majority (208, 72%) of cases had been employed for less than 25% of the follow-up period. The median number of hospital admissions, including at first presentation, was 2 [interquartile range (IQR) 1-4]; a majority (299, 88%) were admitted a least once and a minority (21, 6%) had 10 or more admissions. Overall, outcomes were worse for those with a non-affective diagnosis, for men and for those from South East London.

CONCLUSIONS

Sustained periods of symptom remission are usual following first presentation to mental health services for psychosis, including for those with a non-affective disorder; almost half recover.

Duration of untreated psychosis as predictor of long-term outcome in schizophrenia: systematic review and meta-analysis

BACKGROUND

Duration of untreated psychosis (DUP) is one of the few potentially modifiable predictors of outcomes of schizophrenia. Long DUP as a predictor of poor short-term outcome has been addressed in previous meta-analyses, but the long-term effects of DUP remain unclear.

AIMS

To analyse the associations between DUP and long-term outcomes of schizophrenia.

METHOD

A systematic literature search was performed using seven electronic databases and manual searches. Random effects weighted meta-analysis with correlation coefficients was used to pool the results.

RESULTS

We identified 3493 unique publications, from which 33 samples met our predefined selection criteria. Long DUP correlated statistically significantly with poor general symptomatic outcome, more severe positive and negative symptoms, lesser likelihood of remission and poor social functioning and global outcome (correlations 0.13-0.18). Long DUP was not associated with employment, quality of life or hospital treatment.

CONCLUSIONS

The small but mostly consistent correlation between long DUP and poor outcome indicates that early intervention in psychosis may have at least subtle positive effects on the long-term course of illness.

Predictors of help-seeking duration in adult-onset psychosis in Hong Kong

PURPOSE

Delay in receiving treatment in psychosis may lead to adverse consequences. We examined the predictors for help-seeking duration in adult-onset psychosis Chinese patients in Hong Kong. We hypothesized that factors which are more related to the illness manifestation would be predictive of waiting time before any help-seeking initiation, and factors which are more related to one's knowledge about mental health services would be predictive of help-seeking duration.

METHODS

First-episode patients with psychosis were recruited from the Jockey Club Early Psychosis project. They were asked to report retrospectively all help-seeking behaviors involved since their first occurrence of psychotic symptoms until receipt of effective psychiatric treatment. Baseline characteristics, pre-morbid functioning and traits, and mode of illness onset were assessed.

RESULTS

Help-seeking pattern was analyzed in 360 patients who had subsequently reached the psychiatric services. They had an average of 2.5 help-seeking contacts. Nearly half of the first help-seeking process was initiated by family members. Only 1 % approached priests or traditional healers as the first step in help-seeking. Whereas a gradual mode of onset was significantly associated with longer waiting time to first help-seeking initiation, more premorbid schizoid and schizotypal traits and a migrant status were related to longer help-seeking duration.

CONCLUSIONS

Current findings suggested that family members were the key decision makers in initiating help-seeking. Longer help-seeking duration in migrants has significant implications to both local and global mental health policy.

Evaluation and treatment of children and adolescents with psychotic symptoms

In recent years, there have been increasing efforts to develop early detection and prevention strategies for patients at risk of the development of psychotic disorders. These efforts have led to improved recognition and characterization of psychotic symptoms in youth. This review focuses on the evaluation of children and adolescents with psychotic symptoms who are experiencing functional impairment but who do not meet current criteria for schizophrenia. For this article, emphasis is placed on the evaluation of symptoms, differential diagnosis, and consideration of potential interventions.
