One-year functional outcomes of naturalistically treated patients with schizophrenia

Sex differences in functional outcome after hospitalisation: A systematic review and meta-analysis

The aims of this review were to determine: i) how many studies have examined global functioning outcomes from a psychiatric inpatient stay disaggregated by sex; and ii) if women have worse global functioning outcomes than men following an admission. A systematic review following PRISMA guidance and meta-analysis were conducted. Thirty-six studies met eligibility criteria for inclusion in the review. Of these, eleven papers provided sufficient data to conduct a meta-analysis of global functioning outcomes comparing men and women. Overall, differences between men and women were small. The meta-analysis revealed either no difference or a small significant difference in global functioning outcomes in favour of women, contrary to expectations. As many as 93% of otherwise eligible studies had to be excluded for not disaggregating data by sex. Women may have slightly superior functioning outcomes than men suggesting that inpatient services should be more heavily focused on applying principles of gender-informed care for men as well as women. The finding that so many potential studies had to be excluded for not reporting sex differences is consistent with other mental health literature and highlights a need for better reporting practices in relation to sex differences.

Feasibility of an Intervention Delivered via Mobile Phone and Internet to Improve the Continuity of Care in Schizophrenia: A Randomized Controlled Pilot Study

Schizophrenia is a severe mental illness associated with a heavy symptom burden and high relapse rates. Digital interventions are increasingly suggested as means to facilitate continuity of care, relapse prevention, and long-term disease management for schizophrenia spectrum disorders. In order to investigate the feasibility of a mobile and internet-based aftercare program, a 2-arm randomized controlled pilot study was conducted. The program could be used by patients for six months after inpatient treatment and included psychoeducation, an individual crisis plan, optional counseling via internet chat or phone and a supportive monitoring module. Due to the slow pace of enrollment, recruitment was stopped before the planned sample size was achieved. Reasons for the high exclusion rate during recruitment were analyzed as well as attitudes, satisfaction, and utilization of the program by study participants. The data of 25 randomized patients suggest overall positive attitudes towards the program, high user satisfaction and good adherence to the monitoring module. Overall, the results indicate that the digital program might be suitable to provide support following discharge from intensive care. In addition, the study provides insights into specific barriers to recruitment which may inform future research in the field of digital interventions for severe mental illness.

A Repeated Time-to-Positive Symptoms Improvement among Malaysian Patients with Schizophrenia Spectrum Disorders Treated with Clozapine

Clozapine remains the drug of choice for resistant schizophrenia. However, its dose-response relationship is still controversial. The current investigation aimed to develop a repeated time-to-positive symptoms improvement following the onset of clozapine treatment in Malaysian schizophrenia spectrum disorder patients. Data from patients’ medical records in the Psychiatric Clinic, Penang General Hospital, were retrospectively analyzed. Several parametric survival models were evaluated using nonlinear mixed-effect modeling software (NONMEM 7.3.0). Kaplan–Meier-visual predictive check (KM-VPC) and sampling-importance resampling (SIR) methods were used to validate the final model. A total of 116 patients were included in the study, with a mean follow-up of 306 weeks. Weibull hazard function best fitted the data. The hazard of positive symptoms improvement decreased 4% for every one-year increase in age over the median of 41 years (adjusted hazard ratio (aHR), 0.96; 95% confidence intervals (95% CI), (0.93–0.98)). However, patients receiving a second atypical antipsychotic agent had four-folds higher hazard (aHR, 4.01; 95% CI, (1.97–7.17)). The hazard increased 2% (aHR, 1.02; 95% CI, (1.01–1.03)) for every 1 g increase in the clozapine six months cumulative dose over the median of 34 g. The developed model provides essential information on the hazard of positive symptoms improvement after the first clozapine dose administration, including modifiable predictors of high clinical importance.

Schizophrenia outcomes in the 21st century: A systematic review

OBJECTIVE

We report a review of outcomes in schizophrenia in the twenty-first century, replicating and extending work undertaken by the late Richard Warner in his seminal book, "Recovery from Schizophrenia: Psychiatry and Political Economy" (1985;2004).

METHOD

Warner's methods were followed as closely as possible. Only observational/naturalistic studies were included. Six scientific databases were searched from 2000 to 2020. 6,640 records were retrieved. 47 met inclusion criteria.

RESULTS

Overall, complete recovery is higher in this study than in Warner's (37.75% cf 20.4%), especially for first episode psychosis (FEP) (57.1% cf 20.7%). Clinical recovery, annualized remission rate (ARR), and employment outcomes were significantly superior for first episode psychosis compared with multiple episode psychosis (MEP). ARR shows a trend toward reduction over time, from 2.2 before the financial crash of 2008 to 1.6 after (t = 1.85 df 40 p = .07). The decline is statistically significant for the MEP group (t = 2.32 df18 p = .03). There were no differences in outcome by region, sample characteristics, outcome measures used, or quality of studies. Heterogeneity of clinical outcome measures across the literature makes evidence synthesis difficult. Weak and inconsistent reporting of functional and employment outcomes mean that findings lack meaning with respect to lived experience.

CONCLUSION

Future research strategies should aim to reduce heterogeneity in clinical outcome measures and to increase the emphasis on capture and reporting of more sophisticated measures of social and functional outcome. Outcome domains should be disaggregated rather than conflated into unitary recovery constructs.

Early Improvement of Psychiatric Symptoms with Long-Acting Injectable Antipsychotic Predicts Subsequent Social Functional Remission in Patients with Schizophrenia

PURPOSE

The aim of this study was to clarify whether early symptomatic improvement in response to a long-acting injectable antipsychotic (LAI) contributes to subsequent social functional remission in patients with schizophrenia using the previous clinical trial data (EudraCT registration number: 2011-004889-15). Associations between other factors and social functional remission were also explored.

PATIENTS AND METHODS

We analyzed 428 patients with schizophrenia in which the personal and social performance scale (PSP) and the involvement evaluation questionnaire (IEQ) at the time of the base line were recorded. Social functional remission was defined as participants who scored PSP >70 at the end of 65 weeks. Logistic regression analyses were done to examine associations between social functional remission and clinical and demographic characteristics including early symptomatic response evaluated by Positive and Negative Syndrome Scale (PANSS) at week one.

RESULTS

One hundred out of 428 patients showed social functional remission at the end of the observation period. Shorter duration of illness, higher baseline score of supervision evaluated by IEQ and higher baseline PSP were significantly associated with the social functional remission. Improvement of positive subscale of PANSS at one week was significantly associated with later social functional remission when baseline PSP scores were excluded from predictive variables.

CONCLUSION

Shorter duration of illness, residual type of schizophrenia, higher baseline score of supervision and higher baseline social functioning were predictors of subsequent social functional remission. Although its effect seems to be limited, early symptomatic improvement could be also was a predictor of social functional remission.

Hospital and patient factors influencing the health status among patients with schizophrenia, thirty days after hospital discharge: multi-level analysis

BACKGROUND

The time between discharge from hospital and transition to community and home is a critical period for health status among patients with a mental illness, including patients with schizophrenia. This study aimed to investigate crucial patient factors (patient-level) and hospital factors (hospital-level) affecting health status and see whether patient factor effects on health status vary with hospital factors, 30 days after hospital discharge.

METHODS

This is a prospective study of 1255 patients with schizophrenia and their primary caregivers from 13 public mental hospitals across Thailand. Logistic regression and multi-level logistic regression was used to investigate the effects of patient and hospital factors simultaneously on health status, 30 days after hospital discharge.

RESULTS

The intraclass correlation coefficient indicated that 14% of the change in health status was explained by the differences between hospital. Poor health status was identified in 14.26% of patients, 30 days after hospital discharge. The majority of participant patients were male (69.8%), single (71.87%), and the average age was 38.09 (SD = 9.74). The finding also showed that the patient factors; being female (ORadj .53, 95%CI .31,.92), perceived moderate and high levels of positive aspect of caregiving (ORadj .24, 95%CI .14,.42 and ORadj .05, 95%CI .02,.09), perceived readiness for hospital discharge (ORadj .21, 95%CI .13,.33), partial and full adherence to treatment (ORadj .24, 95%CI .14,.42 and ORadj .31, 95%CI .20,.47) showed a reduced likelihood of developing poor health status except substance use (ORadj 1.55, 95%CI .98, 2.44). Hospital factors; discharge planning process and nurse-patient ratio (ORadj 1.64, 95%CI 1.17, 2.30 and ORadj 1.16, 95%CI 1.09, 1.22) showed an increased likelihood of developing poor health status, 30 days after hospital discharge.

CONCLUSIONS

Findings provide relevant information on how both patient and hospital factors determine health status. These results might lead to better targeting of mental health service policy and enable more precise information gathering and allocation of resources. However, future research should be more focused and continue investigating the pathways through which hospital factors influence health status post-discharge.

Demographic and clinical features as predictors of clozapine response in patients with schizophrenia spectrum disorders: A systematic review and meta-analysis

OBJECTIVES

Clozapine (CLZ) is prescribed to (relatively) treatment-resistant patients with schizophrenia spectrum disorders. Currently, it is unknown what factors predict response to CLZ. Therefore, we performed meta-analyses to identify predictors of CLZ response, hence aiming to facilitate timely and efficient prescribing of CLZ.

METHODS

A systematic search was performed in 'Pubmed' and 'Embase' until 1 January 2019. Articles were eligible if they provided data on predictors of CLZ response measured demographic and clinical factors at baseline or biochemical factors at follow-up in schizophrenia spectrum disorder patients.

RESULTS

A total of 34 articles, total number of participants = 9386; N unique = 2094, were eligible. Factors significantly associated with better CLZ response were: lower age, lower PANSS negative score and paranoid schizophrenia subtype.

CONCLUSION

The results of our meta-analyses suggest that three baseline demographic and clinical features are associated with better clozapine response, i.e. relatively young age, few negative symptoms and paranoid schizophrenia subtype. These variables may be taken into account by clinicians who consider treating a specific patient with CLZ.

Predictive factors of functional remission in patients with early to mid-stage schizophrenia treated by long acting antipsychotics and the specific role of clinical remission

BACKGROUND

Functional remission has become a major therapeutic objective in schizophrenia, but the probability of such positive outcome has a large variability, ranging from 15% to 51%. Additionally, how clinical remission constitutes a prerequisite for functional remission also remains unclear.

METHODS

A prospective observational study was conducted in French schizophrenic patients who initiated treatment with a long-acting injectable (LAI) after an acute episode. Functional and clinical remissions were assessed using the FROGS and the Andreasen criteria, and the role of clinical remission and predictive factors of functional remission was evaluated.

RESULTS

Three hundred three patients with schizophrenia (DSM-IV criteria) were followed for 12 months. At 12 months, 45.1% of the patients reached functional remission while 55.1% obtained clinical remission. Clinical remission facilitated functional remission (OR = 14.74), especially in patients with psychosis for less than 5 years (OR = 23.73). Other predictive factors concerned the family environment, education level, employment status, baseline functioning levels and level of insight.

CONCLUSIONS

About half of patients treated with LAI reached functional remission after one year of follow-up. Reduced clinical symptoms and reaching clinical remission largely favored functional remission. These results stress the importance of continuous and appropriate symptomatic treatment to reach functional remission and maximize recovery chances.

Association of Pre-onset Subthreshold Psychotic Symptoms With Longitudinal Outcomes During Treatment of a First Episode of Psychosis

IMPORTANCE

The clinical high-risk state in psychosis is most often characterized by subthreshold psychotic symptoms (STPS) and represents a target for psychosis prevention. However, evidence suggests that between 30% and 50% of patients with a first episode of psychosis (FEP) report no prior history of STPS, indicating that not all patients with FEP experience a previous clinical high-risk phase. As with other early characteristics of illness onset, this diversity in the early course of symptoms may offer prognostic value for subsequent clinical trajectories.

OBJECTIVE

To determine whether a history of pre-onset STPS is associated with differential 1-year treatment outcomes in an early intervention service for FEP.

DESIGN, SETTING, AND PARTICIPANTS

Data on 195 patients 15 to 35 years of age who were recruited between January 17, 2003, and October 17, 2013, were collected from a catchment-based specialized early intervention service for FEP. Patients who reported experiencing at least 1 STPS prior to the onset of FEP were identified as STPS present (STPSp; n = 135); those who reported no such history were identified as STPS absent (STPSa; n = 60). Statistical analysis was conducted from December 15, 2016, to February 15, 2018.

MAIN OUTCOMES AND MEASURES

Summary scores on the Scale for the Assessment of Positive Symptoms and the Scale for the Assessment of Negative Symptoms, Calgary Depression Scale for Schizophrenia, Hamilton Anxiety Rating Scale, Global Assessment of Functioning scores, and Social and Occupational Functioning Assessment Scale scores at baseline and after 1 year of treatment were analyzed to evaluate 1-year outcomes.

RESULTS

Individuals in the STPSp group (39 female and 96 male participants; mean [SD] age, 23.4 [4.2] years) and the STPSa group (20 female and 40 male participants; mean [SD] age, 23.9 [5.1] years) did not differ in symptom severity or functioning at baseline. Although both groups improved by 1 year of treatment, mixed analyses of covariance (controlling for duration of untreated psychosis) revealed group-by-time interactions for scores on the Scale for the Assessment of Negative Symptoms (F1,192 = 6.17; P = .01), the Global Assessment of Functioning (F1,188 = 7.54; P = .006), and the Social and Occupational Functioning Assessment Scale (F1,192 = 3.79; P = .05). Mixed analyses of covariance also revealed a group effect for scores on the Scale for the Assessment of Positive Symptoms (F1,192 = 5.31; P = .02). After controlling for multiple comparisons, all significant results indicate poorer 1-year outcomes for patients with STPSp compared with patients with STPSa.

CONCLUSIONS AND RELEVANCE

A history of pre-onset STPS consistent with a prior clinical high-risk state is associated with poorer outcomes in psychotic symptoms and global functioning for patients after 1 year of treatment for FEP. The presence or absence of pre-onset STPS therefore has prognostic value for treatment outcomes, even during a later stage of psychotic illness.

Predictors of 'all-cause discontinuation' of initial oral antipsychotic medication in first episode psychosis

INTRODUCTION

Discontinuation of the initial oral antipsychotic prescribed for a first episode of psychosis (FEP) can derail outcome. Our objective was to examine the rate of and time to all-cause discontinuation of the first antipsychotic prescribed and the factors influencing such discontinuation.

METHODS

In a sample of 390 FEP patients, we estimated the rate of and time to discontinuation of the initial antipsychotic over a one-year period. The effects of a number of putative predictors of discontinuation were estimated using regression analyses.

RESULTS

Rate of discontinuation of the first antipsychotic was 72%, with no difference between the 3 investigated antipsychotics (olanzapine (73%), risperidone (68%) and aripiprazole (75%)), (χ² (2) = 1.89, p = 0.388). Mean time to discontinuation was 7.2 (4.6) months and was not different among the three antipsychotics (Log-rank χ² (2) = 0.257, p = 0.879). Binary logistic regression showed that higher positive and negative symptoms remission and baseline functioning were associated with lower rates of discontinuation (Nagelkerke R² = 0.36, χ² (10) = 66.9, p < 0.001). Multiple linear regression showed the same predictors, in addition to male gender and less weight gain per month of exposure to the initial antipsychotic, to be associated with longer time to discontinuation (adjusted R² = 0.336, F (9, 219) = 13.8, p < 0.001).

CONCLUSION

Discontinuation of the initial antipsychotic is a major concern in the course of treating FEP. Symptom relief, better functioning and lower side effects appear to be the major factors associated with continuing an antipsychotic medication.

Psychosocial functioning in patients with psychotic and non-psychotic bipolar I disorder. A comparative study with individuals with schizophrenia

BACKGROUND

More than 50% of individuals with bipolar disorder (BD) do not reach full psychosocial functioning, even during periods of euthymia. It has been suggested that history of psychotic symptoms is one of the factors which are associated with a worse functional outcome. The objective was to compare psychosocial functioning between patients with BD, with (BD-P), and without (BD-NP) a history of psychotic symptoms, and to examine whether the history of psychotic symptoms, or other clinical or neurocognitive variables predict psychosocial functioning.

METHODS

Psychosocial functioning and neurocognition were examined in 100 euthymic patients with bipolar I disorder (50 BD-P, and 50 BD-NP), compared to 50 stabilised patients with schizophrenia (SZ), and 51 healthy controls (HC).

RESULTS

1) There were no differences between BD-P and BD-NP in the GAF-F score or in the FAST total score. 2) The two groups of patients with BD had better scores than SZ both in the GAF-F, and in all measures of the FAST, except for the subscale leisure time. 3) The neurocognitive composite index, verbal memory and subclinical depressive symptoms were the variables which explained a higher percentage of the variance of functional outcome.

LIMITATIONS

The cross-sectional design, and the relatively small sample size are the main limitations.

CONCLUSIONS

A history of psychotic symptoms has no relevant impact on the level of psychosocial functioning in BD. Neurocognitive dysfunction and subclinical depressive symptoms are the variables that best explain the functional impairment. These findings have important clinical implications.

Predicting real-world functional milestones in schizophrenia

Schizophrenia is a severe disorder that often causes impairments in major areas of functioning, and most patients do not achieve expected real-world functional milestones. The aim of this study was to identify which variables of demography, illness activity, and functional capacity predict patients' ability to attain real-world functional milestones. Participants were 235 outpatients, 149 men and 86 women, diagnosed with schizophrenia spectrum disorder. Our results showed that younger patients managed to achieve a higher level of functioning in educational level, marital status, and social contacts. Patients' functional capacity was primarily associated with educational level and housing situation. We also found that women needed less support regarding housing and obtained a higher level of marital status as compared with men. Our findings demonstrate the importance of considering current symptoms, especially negative symptoms, and remission stability over time, together with age, duration of illness, gender, educational level, and current functional capacity, when predicting patients' future real-world functioning. We also conclude that there is an advantage in exploring symptoms divided into positive, negative, and general domains considering their probable impact on functional achievements.

Outcomes of inpatients with severe mental illness: a naturalistic descriptive study

Objective:

To describe and evaluate the response and predictors of remission during inpatient treatment in a psychiatric unit in a general hospital based on symptomatology, functionality, and quality of life (QoL).

Methods:

Patients were admitted to a psychiatric unit in a tertiary general hospital in Brazil from June 2011 to December 2013 and included in the study if they met two of the severe mental illness (SMI) criteria: Global Assessment of Functioning (GAF) ≤ 50 and duration of service contact ≥ 2 years. Patients were assessed by the Brief Psychiatric Rating Scale (BPRS), the Clinical Global Impression (CGI) Severity Scale , GAF, the World Health Organization Quality of Life Instrument – Abbreviated version (WHOQOL-Bref), and specific diagnostic scales.

Results:

A total of 239 patients were included. BPRS mean scores were 25.54±11.37 at admission and 10.96±8.11 at discharge (p < 0.001). Patients with manic episodes (odds ratio: 4.03; 95% confidence interval: 1.14-14.30; p = 0.03) were more likely to achieve remission (CGI ≤ 2 at discharge) than those with depressive episodes. Mean length of stay was 28.95±19.86 days. All QoL domains improved significantly in the whole sample.

Conclusion:

SMI patients had marked improvements in symptomatic and functional measures during psychiatric hospitalization. Patients with manic episodes had higher chance of remission according to the CGI.

Predictors of vocational status in schizophrenia patients--Results from the Polish nationwide survey

BACKGROUND

Steady employment constitutes one of most important aspects of functional recovery in schizophrenia. Therefore, there is a need for understanding clinical and demographic factors predicting vocational status in schizophrenia.

METHODS

Clinical and demographic data of 1,010 schizophrenia patients were gathered from public outpatient clinics. We compared patients who maintained employment between the diagnosis time point and the day of assessment, with the patients who were employed in the diagnosis time point but were unemployed on the day of assessment with respect to clinical and demographic variables.

RESULTS

Lower educational attainment, lower-income region of residence, medical comorbidities (obesity, diabetes and hypertension), first hospitalization at inpatient unit in comparison with the day hospital, higher total number of hospitalizations and the number of inpatient hospitalizations were found to serve as predictors of unemployment throughout the course of schizophrenia. After application of Bonferroni correction and logistic binary regression analysis, lower educational attainment, higher number of inpatient hospitalizations and obesity predicted unemployment.

CONCLUSION

Education, obesity and the number of inpatient hospitalizations seem to predict vocational outcome in schizophrenia. This study warrants further investigation of medical comorbidities in schizophrenia in terms of social consequences in order to indicate the direction of this relationship.

Functional deterioration from the premorbid period to 2 years after the first episode of psychosis in early-onset psychosis

The aim of the study was to analyze changes in functional adjustment from childhood to 2 years after the first episode of psychosis (FEP) in patients with early-onset schizophrenia spectrum disorders (SSD) and affective psychoses (AFP) and a good or intermediate level of premorbid adjustment. We followed 106 adolescents (aged 12-17 years) with FEP for 2 years after recruitment. Premorbid adjustment in childhood was assessed in 98 patients with the childhood subscale of the Cannon-Spoor Premorbid Adjustment Scale (c-PAS). Global functioning was assessed 2 years after the FEP with the Children's Global Assessment Scale (c-GAS) or the Global Assessment of Functioning scale (GAF), as appropriate. Functional deterioration was defined as a downward shift in the level of functional adjustment from childhood to 2 years after the FEP. In patients with good or intermediate premorbid adjustment, functional deterioration was observed in 28.2 % (26.5 % of the AFP group, 29.4 % of the SSD group). Longer duration of untreated psychosis (Beta = 0.01; P = 0.01) and higher symptom severity at the FEP, as measured with the Clinical Global Impression Scale (Beta = 1.12; P = 0.02), significantly predicted the presence of functional deterioration, accounting for 21.4 % of the variance. Irrespective of diagnosis (SSD or AFP), almost one-third of adolescents with FEP and good or intermediate premorbid adjustment showed functional deterioration from the premorbid period to 2 years after the FEP.

Clinical predictors of therapeutic response to antipsychotics in schizophrenia

The search for clinical outcome predictors for schizophrenia is as old as the field of psychiatry. However, despite a wealth of large, longitudinal studies into prognostic factors, only very few clinically useful outcome predictors have been identified. The goal of future treatment is to either affect modifiable risk factors, or use nonmodifiable factors to parse patients into therapeutically meaningful subgroups. Most clinical outcome predictors are nonspecific and/or nonmodifiable. Nonmodifiable predictors for poor odds of remission include male sex, younger age at disease onset, poor premorbid adjustment, and severe baseline psychopathology. Modifiable risk factors for poor therapeutic outcomes that clinicians can act upon include longer duration of untreated illness, nonadherence to antipsychotics, comorbidities (especially substance-use disorders), lack of early antipsychotic response, and lack of improvement with non-clozapine antipsychotics, predicting clozapine response. It is hoped that this limited capacity for prediction will improve as pathophysiological understanding increases and/or new treatments for specific aspects of schizophrenia become available.

Functional outcome in major psychiatric disorders and associated clinical and psychosocial variables: A potential cross-diagnostic phenotype for further genetic investigations?

OBJECTIVES

Functional outcome has recently become of interest for cross-diagnostic subphenotype approaches in psychiatric genetics. Therefore, it is crucial to know about clinical, demographic and psychosocial variables that correlate with long-term functioning. Unfortunately, there is a lack of studies that directly compare the importance of correlates for functional outcome between different disorders.

METHODS

Applying regression models to samples of patients with schizophrenia (SZ, n = 238), bipolar disorder (BD, n = 533) and major depressive disorder (MDD, n = 398), we compared the magnitude of association of potential correlates with functional outcome, measured by the Global Assessment of Functioning (GAF) score.

RESULTS

Shared correlates for worse functional outcome were poor premorbid functioning, insidious illness onset and poor premorbid work or social adjustment in all three disorders, and negative symptomatology in SZ and BD. Disorder-specific correlates for SZ were longer duration of illness, lower functioning during episodes and being life-time single, for BD substance abuse and suicidality, and for MDD premorbid unemployment and having a premorbid personality disorder.

CONCLUSIONS

We found different patterns of correlates for long-term functioning in SZ, BD and MDD. Knowledge of these patterns may improve the quality of genetic investigations focussing on functional outcome.

From hospital admission to independent living: is prediction possible?

An integral component of recovery from mental illness is being able to engage in everyday activities. This ability is often restricted among people with schizophrenia. Although functional deficits are addressed during hospitalization, the ability to predict daily functioning based on information gathered during hospitalization has not been well established. This study examines whether measurements completed during hospitalization can be useful for predicting independent living within the community. Inpatients with schizophrenia (N=104) were enrolled in the study and assessed for cognitive functioning, functional capacity and symptoms. They were approached again 6 months after discharge to evaluate their functioning with respect to everyday life Instrumental Activities of Daily Living (IADL) and Activities of Daily Living (ADL). Functional capacity during hospitalization predicted 26.8% of ADL functioning and 38.8% of IADL functioning. ADL was best predicted by the severity of negative symptoms, cognitive functioning, and the number of hospitalizations (51.2%), while IADL was best predicted by functional capacity, cognition, and number of hospitalizations (60.1%). This study provides evidence that evaluations during hospitalization can be effective, and demonstrates the advantage of a holistic approach in predicting daily functioning. When a holistic approach is not practical, a functional capacity measurement may serve as an effective predictor.

The social functional outcome of being naturalistically treated with paliperidone extended-release in patients with schizophrenia

BACKGROUND

Social functioning is an important outcome for patients with schizophrenia. To evaluate the effects of paliperidone extended-release (PAL-ER) on social function, symptomatology, and safety in the routine clinical practice, we conducted a 1-year post-marketing surveillance study of PAL-ER. We also explored relationships between symptomatic improvement and socially functional outcome in patients with schizophrenia.

PATIENTS AND METHODS

Patients with an established diagnosis of schizophrenia were allowed flexible 3-12 mg/day dosing during the surveillance. Patients were assessed on social functioning using the Social and Occupational Functioning Assessment Scale (SOFAS) and on symptomatology using the Clinical Global Impression-Schizophrenia scale. All adverse events (AEs) were also collected.

RESULTS

A total of 1,429 patients were enrolled in the surveillance study, of whom 1,405 were evaluable for safety and 1,142 were evaluable for efficacy. The treatment discontinuation rate for any reason during the observation period was 34.66%. Significant improvements were observed on both Social and Occupational Functioning Assessment Scale and Clinical Global Impression-Schizophrenia scale during the observation period. The percentage of patients with socially functional remission (SOFAS ≥61) also increased significantly. A significant association between early improvements in positive symptoms, sex, severity of negative symptoms at baseline, and socially functional remission was observed. A total of 33.52% of patients had AEs and 8.75% of patients had serious AEs. Despite the recommendation of monotherapy with PAL-ER, 65.84% of patients were given additional antipsychotics (polypharmacy). Post hoc comparisons of monotherapy versus polypharmacy revealed that the monotherapy group had better outcomes and fewer AEs than the polypharmacy treated group. The improvement in social functioning and the rate of socially functional remission did not differ between groups.

CONCLUSION

PAL-ER treatment showed effective symptom control and improvement in social functioning. The data suggest that early response to antipsychotic treatment should be important for functional outcomes.

Which aspects of long-term outcome are predicted by positive and negative symptoms in early-onset psychosis? An exploratory eight-year follow-up study

BACKGROUND

Early-onset psychoses show substantial variability of diagnostic and functional outcome. Finding reliable prognostic factors may allow to allocate resources to those with the worst prognosis. The aim of the study was to gain new insights regarding the potential value of baseline negative and positive symptoms as predictors of outcome in psychoses of early onset.

METHOD

Sixty-three patients with early-onset schizophrenia spectrum psychosis hospitalized in an adolescent psychiatry unit were assessed with the Positive and Negative Syndrome Scale during the index admission. Associations with diagnosis, illness course and functional outcome were analysed in mean 8 years of follow-up (range 3.4-13.5 years).

RESULTS

The mean age at the index admission and the follow-up was 16.6 ± 1.2 and 24.5 ± 3.0 years, respectively. A significant majority of subjects continued psychiatric treatment (95%) and had been readmitted (71%). The mortality rate was 3% (suicide and accident). Negative symptoms were related to mental health service utilization during the follow-up. General severity of symptoms, specifically positive and cognitive factors were associated with the diagnosis of schizophrenia and inversely with diagnostic shift outside the schizophrenia spectrum at the catamnesis. Poor impulse control at baseline was associated with worse functional outcome. The drug-free subgroup with no occupational/educational activity compared with the drug-treated subjects showed lower levels of baseline negative symptomatology.

CONCLUSION

The study findings suggest that in patients with early-onset psychosis negative and positive symptoms show a differential prognostic value. Pharmacotherapy may attenuate the effect of symptoms on functional outcome. These hypotheses need to be tested in future studies using confirmatory approaches.

Employment and the associated impact on quality of life in people diagnosed with schizophrenia

A systematic review was conducted to assess the employment rate of people with schizophrenia. Additionally, information from the selected studies concerning factors associated with employment and health-related quality of life (HRQoL) was examined. Employment rates ranged from 4% to 50.4%. The studies differed considerably in design, patient settings, and methods of recruitment. The most frequently reported factors associated with employment were negative and cognitive symptoms, age of onset, and duration and course of the disease. Individual characteristics associated with unemployment were older age, lower education, and sex (female). Additionally, environmental factors, eg, the availability of welfare benefits and vocational support programs, seemed to play a role. Generally, being employed was positively associated with HRQoL. However, the causal direction of this association remained unclear, as studies on the bidirectional relationship between employment and HRQoL were lacking.

Are we really mapping psychosis risk? Neuroanatomical signature of affective disorders in subjects at ultra high risk

BACKGROUND

The majority of people at ultra high risk (UHR) of psychosis also present with co-morbid affective disorders such as depression or anxiety. The neuroanatomical and clinical impact of UHR co-morbidity is unknown.

METHOD

We investigated group differences in grey matter volume using baseline magnetic resonance images from 121 participants in four groups: UHR with depressive or anxiety co-morbidity; UHR alone; major depressive disorder; and healthy controls. The impact of grey matter volume on baseline and longitudinal clinical/functional data was assessed with regression analyses.

RESULTS

The UHR-co-morbidity group had lower grey matter volume in the anterior cingulate cortex than the UHR-alone group, with an intermediate effect between controls and patients with major depressive disorder. In the UHR-co-morbidity group, baseline anterior cingulate volume was negatively correlated with baseline suicidality/self-harm and obsessive-compulsive disorder symptoms.

CONCLUSIONS

Co-morbid depression and anxiety disorders contributed distinctive grey matter volume reductions of the anterior cingulate cortex in people at UHR of psychosis. These volumetric deficits were correlated with baseline measures of depression and anxiety, suggesting that co-morbid depressive and anxiety diagnoses should be carefully considered in future clinical and imaging studies of the psychosis high-risk state.

Does employment alter the course and outcome of schizophrenia and other severe mental illnesses? A systematic review of longitudinal research

INTRODUCTION

This review synthesized prospective evidence to assess whether achieving employment alters the course of schizophrenia-spectrum disorder.

METHOD

Researchers identified relevant analyses for review via PubMed, expert referral, and reference review and systematically applied two levels of screening to 1484 citations using seven a priori criteria.

RESULTS

A total of 12 analyses representing eight cohorts, or 6844 participants, compared illness course over time by employment status in majority schizophrenia-spectrum samples. Employment was consistently associated with reductions in outpatient psychiatric treatment (2 of 2 studies) as well as improved self-esteem (2 of 2 studies). Employment was inconsistently associated with positive outcomes in several other areas, including symptom severity, psychiatric hospitalization, life satisfaction, and global wellbeing. Employment was consistently unrelated to worsening outcomes.

DISCUSSION

Achieving employment does not cause harm among people with schizophrenia-spectrum disorder and other severe mental illnesses. Further detailed mechanistic analyses of adequately powered long-term follow-up studies using granular descriptions of employment are needed to clarify the nature of associations between employment and hypothesized benefit.

Prospective memory predicts the level of community living skills in schizophrenia

Schizophrenia patients are known to have prospective memory (PM) deficits. There is no robust evidence showing that PM deficits have a major impact on community living skills in schizophrenia. The aim of this study was to examine the association between PM and community living skills in schizophrenia. Forty-four individuals with schizophrenia formed the study sample. Participants׳ psychopathology, prospective and retrospective memory, level of intelligence, and community living skills were measured with standardized instruments. In bivariate analyses, community living skills overall but not self-care correlated with PM total and subscales scores. In multivariate analyses, event-based PM was more predictive than time-based PM of the level of community living skills. In conclusion, PM has a significant impact on community living skills in schizophrenia and attention should be paid to this type of memory disturbance in rehabilitation of schizophrenia.

Identification of psychopathological course trajectories in schizophrenia

Course trajectory analyses have been performed primarily for treatment response in acute episodes of schizophrenic disorders. As yet, corresponding data for the long-term course are lacking. Within a multicenter prospective observational study, 268 patients with schizophrenia were assessed at discharge from hospital and followed up after 6, 12, 18, and 24 months. A latent class growth analysis was performed on the scores from the Positive and Negative Syndrome Scale (PANSS). A two-class conditional latent class model showed the best data fit (Entropy: 0.924). The model divided the sample into a group with amelioration in all PANSS subscales (60%) and a group with stable positive/negative and deteriorating general psychopathology symptoms (40%). Global functioning (GAF score), gender, age, living situation and involuntary admission predicted course trajectory class membership. The model was predictive of significant differences between the two groups in health care service costs and quality of life. The results underline the heterogeneous course of the illness, which ranged from amelioration to deterioration over a 2-year period. Statistical models such as trajectory analysis could help to identify more homogenous subtypes in schizophrenia.

Improvement of functional independence of patients with acute schizophrenia through early occupational therapy: a pilot quasi-experimental controlled study

Objective:

To clarify whether early occupational therapy for patients with acute schizophrenia improves their functional independence.

Design:

Quasi-experimental controlled study.

Setting:

A university hospital in Japan.

Subjects:

Forty-six out of 85 eligible patients with schizophrenia.

Intervention:

Participants were allocated into an intervention group or a control group according to the month of admission. Activities in one-on-one and mainly non-verbal occupational therapy were provided for the intervention group immediately after admission, and not for the control group.

Main measures:

Functional independence was measured using the Functional Independence Measure (FIM), at admission, at one month and at three months after admission. Psychiatric symptoms were also measured by the Brief Psychiatric Rating Scale.

Results:

Patients in both groups showed improved FIM total scores at one month and three months after admission. In the intervention group, the medians (interquartile ranges) were 89.0 (44.5) at admission, 113.0 (18.5) at one month, and 121.0 (6.5) at three months. In the control group, they were 88.0 (32.0), 107.0 (39.5), and 111.0 (17.0). At three months, the total FIM scores were significantly higher in the intervention group than in the control group ( p = 0.016). In the FIM cognitive domain, the scores were significantly higher in the intervention group than in the control group at one month ( p = 0.038) and, three months ( p = 0.012). Both groups showed improvement in Brief Psychiatric Rating Scale total scores, while no significant differences were observed between the groups at any points.

Conclusion:

The results suggest that early occupational therapy may improve functional independence in patients with acute schizophrenia.

Predictors of response to second generation antipsychotics in drug naïve patients with schizophrenia: a 1 year follow-up study in Shanghai

Response and remission are of great importance to patients with first-episode schizophrenia. Although previous researches have revealed characteristics related to medication response, there is rarely data over remission-related factors. We presume that factors correlated to response may also influence remission in 1 year treatment for first-episode schizophrenia. 398 drug-naïve patients met the criteria of schizophrenia using ICD-10 criteria were recruited from Shanghai Mental Health Center and treated with one of three second generation antipsychotics (risperidone, olanzapine or quetiapine). Patients were followed up for 1 year and assessed at 2 weeks, and then 2, 3, 6, 8 and 12 months. Severity of symptom was evaluated using the Chinese version of the Positive and Negative Syndrome Scale (PANSS). Response was defined as a reduction of 50% or more PANSS scores. The 8-item criteria of remission (proposed by the Remission of Schizophrenia Working Group) were used. Logistic regression analysis revealed that shorter duration of untreated psychosis (DUP), longer treatment time, higher baseline PANSS positive score and higher PANSS general pathological scores predicted response, and acute prodromal phase was the independent factor for remission. These results indicate baseline characters that related to response and those related to remission may be different for patients with schizophrenia.

Is it true remission? A study of remitted patients affected by schizophrenia and schizoaffective disorders

To date, few studies have reported analytical data relating to clinical remission, functional remission and subjective experience. The present study aimed to investigate these aspects in a sample of chronic outpatients.

METHODS

112 schizophrenic or schizoaffective outpatients (Males=60; Females=52; mean age 43.5 ± 9.42 yr) were evaluated with regard to symptomatology (SCID-I; PANSS, CGI-SCH scales), functioning (PSP scale), subjective wellbeing (SWN-K scale) and Quality of Life (WHO-QoL-Bref scale).

RESULTS

50% of patients were found to be in remission. Significantly higher scores at PANNS, CGI-SCH, PSP, but not at SWN and WHO-QoL, were found among remitted patients; a relevant proportion of remitted subjects continued to manifest a moderate level of symptoms (score >3) both at PANSS (35% of cases) and CGI-SCH (29% of cases), significant functional impairment (total score <70) at PSP (68% of cases ), and a lesser degree of wellbeing (total score <80) at SWN-K (34% of cases).

CONCLUSION

patients in whom clinical remission was confirmed may display persisting symptoms, relevant areas of functional impairment and a decreased sense of wellbeing.

Working memory as a predictor of negative symptoms and functional outcome in first episode psychosis

The relationship of neurocognitive course with clinical and functional outcomes in psychosis is not well known, especially in the long term. The aim of the study was to examine the clinical and neuropsychological course of first-episode psychosis patients at 5-year follow-up and analyze the relationship of cognitive performance with clinical and functional outcome. The 5-year follow-up was conducted with 26 first-episode psychosis patients. Psychotic symptoms were measured by the Positive and Negative Syndrome Scale, manic and depressive symptoms by the Young Mania Rating Scale and Hamilton Depression Rating Scale respectively, and psychosocial functioning by the Functioning Assessment Short Test. The cognitive domains were assessed by the Wechsler Adult Intelligence Scale, the Wisconsin Card Sorting Test, the Trail Making Test, the Verbal Fluency Test, the Stroop Colour-Word Test and the Wechsler Memory Scale. Patients showed symptomatic improvement in the follow-up except in negative psychotic symptoms. There was also improvement in most cognitive domains except in working memory and processing speed in the follow-up. Working memory impairment was associated to negative psychotic symptoms and poor functional outcomes. Negative symptoms mediated the relationship between working memory and outcome. Therefore, negative symptoms should be a primary target of treatment to improve functional outcomes.
