Prevalence, predictors, and consequences of long-term refusal of antipsychotic treatment in first-episode psychosis

An open label pilot trial of low-dose lithium for young people at ultra-high risk for psychosis

AIM

Lithium, even at low doses, appears to offer neuroprotection against a wide variety of insults. In this controlled pilot, we examined the safety (i.e., side-effect profile) of lithium in a sample of young people identified at ultra-high risk (UHR) for psychosis. The secondary aim was to explore whether lithium provided a signal of clinical efficacy in reducing transition to psychosis compared with treatment as usual (TAU).

METHODS

Young people attending the PACE clinic at Orygen, Melbourne, were prescribed a fixed dose (450 mg) of lithium (n = 25) or received TAU (n = 78). The primary outcome examined side-effects, with transition to psychosis, functioning and measures of psychopathology assessed as secondary outcomes.

RESULTS

Participants in both groups were functionally compromised (lithium group GAF = 56.6; monitoring group GAF = 56.9). Side-effect assessment indicated that lithium was well-tolerated. 64% (n = 16) of participants in the lithium group were lithium-adherent to week 12. Few cases transitioned to psychosis across the study period; lithium group 4% (n = 1); monitoring group 7.7% (n = 6). There was no difference in time to transition to psychosis between the groups. No group differences were observed in other functioning and symptom domains, although all outcomes improved over time.

CONCLUSIONS

With a side-effect profile either comparable to, or better than UHR antipsychotic trials, lithium might be explored for further research with UHR young people. A definitive larger trial is needed to determine the efficacy of lithium in this cohort.

Rates and correlates of medication non-adherence behaviors and attitudes in adult patients with early psychosis

PURPOSE

Literature on antipsychotic medication adherence in early psychosis primarily assessed adherence behaviors and focused on young patients. There is a paucity of research investigating negative medication attitude and its determinants in the early illness course, particularly in older-aged sample. We aimed to examine prevalence and correlates of medication non-adherence behaviors and negative medication attitudes separately in adult patients with early psychosis.

METHODS

One hundred ninety-nine Chinese early psychosis patients aged 26-55 years who had received three-year treatment for first psychotic episode in Hong Kong were examined. Assessments encompassing socio-demographics, premorbid adjustment, clinical and treatment profiles, self-stigma and therapeutic alliance were conducted. Patients were evaluated with Medication Compliance Questionnaire, which is a modified Chinese-translated version of Medication Adherence Rating Scale and includes items measuring adherence behaviors and attitudes towards medications.

RESULTS

Rates of medication non-adherence and negative attitude towards medications were 38.7% and 50.8%, respectively. Multivariate regression analysis showed that more severe positive symptoms, greater self-stigma and negative medication attitude were independently associated with medication non-adherence. Negative attitude towards medications was significantly associated with younger age, higher educational attainment, diagnosis of other psychotic disorders, poorer insight, greater self-stigma and less satisfaction with communication with healthcare staff, which represented an index reflecting suboptimal therapeutic alliance.

CONCLUSION

Antipsychotic non-adherence and negative medication attitudes are frequently observed in adult early psychosis patients. Our findings indicate that poor insight, elevated self-stigma and suboptimal therapeutic alliance may constitute potential treatment targets for promoting medication adherence and rectifying negative medication attitudes in the early illness stage.

Treatment adherence rates across different psychiatric disorders and settings: findings from a large patient cohort

Approximately 50% of patients with psychiatric disorders do not fully adhere to the prescribed psychopharmacological therapy, significantly impacting the progression of the disorder and the patient's quality of life. The present study aimed to assess potential differences in terms of rates and clinical features of treatment adherence in a large cohort of psychiatric patients with different diagnoses attending various psychiatric services. The study included 307 psychiatric patients diagnosed with a primary major depressive disorder, bipolar disorder, anxiety disorder, schizophrenic spectrum disorder, or personality disorder. Patient's adherence to treatment was evaluated using the Clinician Rating Scale, with a cutoff of at least five defining adherence subgroups. One-third of the sample reported poor medication adherence. A lower rate of adherence emerged among patients with schizophrenic spectrum disorder and bipolar disorder. Subjects with poor adherence were more frequently inpatients and showed higher current substance use, a greater number of previous hospitalizations, and more severe scores at psychopathological assessment compared with patients with positive adherence. Poor adherence was associated with symptom severity and increased rates of relapses and rehospitalizations. In addition, substance use appears to be an unfavorable transdiagnostic factor for treatment adherence.

An SMS text messaging intervention to improve clinical engagement in early psychosis: A pilot randomized-controlled trial

Disengagement of youth with psychosis from Early Psychosis Intervention (EPI) services continues to be a significant barrier to recovery, with approximately one-third prematurely discontinuing treatment despite the ongoing need. The current pilot trial sought to evaluate the preliminary efficacy and feasibility of a weekly short message service (SMS) intervention to improve engagement in EPI services. This was a longitudinal single-blinded randomized control trial in which participants were assigned to receive either an active or sham SMS intervention over nine months. Sixty-one participants with early psychosis between the ages of 16 and 29 were enrolled, randomized, and received at least part of the intervention. Primary outcomes consisted of participant clinic attendance rates over the course of the intervention and clinician-rated engagement. Secondary measures included patient-rated therapeutic rapport, attitude toward medication, psychopathology, cognition, functioning, and intervention feedback from participants. Compared to the sham group, participants receiving the active intervention did not show improved appointment attendance rates; however, did exhibit some improvements in aspects of engagement, including improved clinician-rated availability, attitude toward medication, positive symptoms, avolition-apathy and social functioning. Thus, contrary to our hypotheses, digitally augmented care did not result in enhanced engagement in EPI services, as measured by clinic attendance, although with some indication that it may contribute to improved attitude toward medication and, potentially, medication adherence. Weekly SMS text messaging appeared to result in a pattern of engagement whereby individuals who were improving clinically attended appointments less often, possibly due to inadvertent use of the intervention to check in with clinicians.

Influencing factors of medication adherence in schizophrenic patients: a meta-analysis

Medication adherence of schizophrenic patients is a growing public health problem. We conducted a meta-analysis on the influencing factors of medication compliance in schizophrenic patients. We searched PubMed, Embase, Cochrane Library, and Web Of Science for relevant articles published up to December 22, 2022. Combined odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess influencing factors. Egger's test, funnel plot, the trim and fill method, and meta-regression analysis were used to assess publication bias. A total of 20 articles were included in the analysis. Twenty influencing factors were divided into seven categories: drug factors (OR = 1.96, 95% CI: 1.48-2.59), problem behavior (OR = 1.77, 95% CI: 1.43-2.19), income and quality of life (OR = 1.23, 95% CI: 1.08-1.39), personal characteristics (OR = 1.21, 95% CI: 1.14-1.30), disease factors (OR = 1.14, 95% CI: 1.98-1.21), support level (OR = 0.54, 95% CI: 0.42-0.70), and positive attitude and behavior (OR = 0.52, 95% CI: 0.45-0.62). This meta-analysis found that drug factors, disease factors, problem behavior, low income and quality of life, and factors related to personal characteristics appear to be risk factors for medication adherence in people with schizophrenia. And support level, positive attitude and behavior appear to be protective factors.

The Safety and Efficacy of Psychosocial Adherence Interventions in Young People with Early Psychosis: A Systematic Review

Background: The role of antipsychotic medication in supporting young people in their recovery from early psychosis is complex and controversial. It is common for young people, often given antipsychotic medication for the first time, to express a choice to stop treatment, potentially increasing the risk of relapse and admission to hospital. Our systematic review aimed to evaluate the safety and effectiveness of psychosocial interventions to enhance antipsychotic medication adherence in young people with early psychosis. Methods: We reviewed studies using any experimental design of psychosocial interventions specifically focused on enhancing adherence with antipsychotic medication in young people with early psychosis. Cochrane CENTRAL Register, Medline, Embase, PsychINFO and CINAHL were searched on 19 November 2021 without time restriction. Studies were assessed for quality using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Results: Our initial search identified 3469 documents. Following title, abstract and full-text screening, we included three published studies and one unpublished experimental study that met our inclusion criteria. Outcome data were available for three studies that tested adherence–coping–education, adherence therapy, and a health dialogue intervention, all having a positive effect on medication adherence. None of the trials reported data on the safety of the experimental interventions. Conclusion: There is a paucity of evidence from high-quality randomized controlled trials that establish the safety and effectiveness of any type of psychosocial intervention to enhance medication adherence in young people with early psychosis. Further high-quality trials are warranted. This review was registered on the Open Science Framework prior to undertaking out initial searches.

Digital smartphone intervention to recognise and manage early warning signs in schizophrenia to prevent relapse: the EMPOWER feasibility cluster RCT

BACKGROUND

Relapse is a major determinant of outcome for people with a diagnosis of schizophrenia. Early warning signs frequently precede relapse. A recent Cochrane Review found low-quality evidence to suggest a positive effect of early warning signs interventions on hospitalisation and relapse.

OBJECTIVE

How feasible is a study to investigate the clinical effectiveness and cost-effectiveness of a digital intervention to recognise and promptly manage early warning signs of relapse in schizophrenia with the aim of preventing relapse?

DESIGN

A multicentre, two-arm, parallel-group cluster randomised controlled trial involving eight community mental health services, with 12-month follow-up.

SETTINGS

Glasgow, UK, and Melbourne, Australia.

PARTICIPANTS

Service users were aged > 16 years and had a schizophrenia spectrum disorder with evidence of a relapse within the previous 2 years. Carers were eligible for inclusion if they were nominated by an eligible service user.

INTERVENTIONS

The Early signs Monitoring to Prevent relapse in psychosis and prOmote Wellbeing, Engagement, and Recovery (EMPOWER) intervention was designed to enable participants to monitor changes in their well-being daily using a mobile phone, blended with peer support. Clinical triage of changes in well-being that were suggestive of early signs of relapse was enabled through an algorithm that triggered a check-in prompt that informed a relapse prevention pathway, if warranted.

MAIN OUTCOME MEASURES

The main outcomes were feasibility of the trial and feasibility, acceptability and usability of the intervention, as well as safety and performance. Candidate co-primary outcomes were relapse and fear of relapse.

RESULTS

We recruited 86 service users, of whom 73 were randomised (42 to EMPOWER and 31 to treatment as usual). Primary outcome data were collected for 84% of participants at 12 months. Feasibility data for people using the smartphone application (app) suggested that the app was easy to use and had a positive impact on motivations and intentions in relation to mental health. Actual app usage was high, with 91% of users who completed the baseline period meeting our a priori criterion of acceptable engagement (> 33%). The median time to discontinuation of > 33% app usage was 32 weeks (95% confidence interval 14 weeks to ∞). There were 8 out of 33 (24%) relapses in the EMPOWER arm and 13 out of 28 (46%) in the treatment-as-usual arm. Fewer participants in the EMPOWER arm had a relapse (relative risk 0.50, 95% confidence interval 0.26 to 0.98), and time to first relapse (hazard ratio 0.32, 95% confidence interval 0.14 to 0.74) was longer in the EMPOWER arm than in the treatment-as-usual group. At 12 months, EMPOWER participants were less fearful of having a relapse than those in the treatment-as-usual arm (mean difference -4.29, 95% confidence interval -7.29 to -1.28). EMPOWER was more costly and more effective, resulting in an incremental cost-effectiveness ratio of £3041. This incremental cost-effectiveness ratio would be considered cost-effective when using the National Institute for Health and Care Excellence threshold of £20,000 per quality-adjusted life-year gained.

LIMITATIONS

This was a feasibility study and the outcomes detected cannot be taken as evidence of efficacy or effectiveness.

CONCLUSIONS

A trial of digital technology to monitor early warning signs that blended with peer support and clinical triage to detect and prevent relapse is feasible.

FUTURE WORK

A main trial with a sample size of 500 (assuming 90% power and 20% dropout) would detect a clinically meaningful reduction in relapse (relative risk 0.7) and improvement in other variables (effect sizes 0.3-0.4).

TRIAL REGISTRATION

This trial is registered as ISRCTN99559262.

Dynamics between insight and medication adherence in first-episode psychosis: Study of 3-year trajectories

Background

While specialized early intervention programs represent the gold standard in terms of optimal management of first-episode psychosis (FEP), poor medication adherence remains a predominant unmet need in the treatment of psychosis. In this regard, an interaction between insight and adherence in FEP patients has been hypothesized but has been challenged by multiple pitfalls.

Methods

Latent profile analysis and trajectory modeling techniques were used to evaluate insight and adherence of 331 FEP patients engaged at the beginning, middle, and end of a 3-year specialized early psychosis program. A Bayesian model comparison approach was used to compare scores of clinical, functional, and socioeconomic outcomes at the end point of the study.

Results

Nearly one-third of the patients maintain a high level of insight and adherence during the entire program. At the end of the 3-year follow-up, more than three-quarters of patients are considered adherent to their medication. Patients with low levels of insight and adherence at the beginning of the program improve first in terms of adherence and then of insight. Furthermore, patients with high levels of insight and adherence are most likely to reach functional recovery and to experience an increase in environmental quality of life.

Conclusions

Latent FEP subpopulations can be identified based on insight and adherence. Medication adherence was the first variable to improve, but a gain in insight possibly plays a role in the reinforcement of adherence.

Detecting signs of deterioration in young patients with serious mental illness: a systematic review

BACKGROUND

Serious mental illnesses (SMI) such as schizophrenia and bipolar disorder first develop between ages 14 and 25. Once diagnosed, young peoples' health can deteriorate, and it is therefore vital to detect this early to prevent severe outcomes including hospitalisations and deaths by suicide. The main study aim is to describe and discuss observational studies that examine signs of deterioration in young patients with SMI.

METHODS

A systematic review guided by the published protocol was conducted. Cumulative Index to Nursing and allied Health Literature (CINAHL), MEDLINE, Embase, PsycINFO, Health Management Information Consortium (HMIC) and Web of Science were searched against pre-defined criteria until 1 March 2021. Observational studies were extracted according to design, country, participant, indicator, outcome and main finding categories. Quality was assessed independently using the Newcastle Ottawa Scale (NOS).

RESULTS

Of the 15,788 publications identified, 5 studies were included and subjected to narrative synthesis. Two indicators of mental health deterioration were identified: cognitive functioning (decline, worsening and poor school/academic performance) and expressed emotion status. Indicators revealed mixed views on predicting deterioration. Worsening cognitive functioning and expressed emotion status significantly predicted medication non-adherence and relapse respectively. However, a decline in cognitive functioning (poor academic performance) was not found to significantly correlate to deaths by suicide. Study quality was mostly poor and associations between indicators and varied outcomes were weak. The heterogeneous nature of the data made comparisons difficult and did not allow for further statistical analysis.

CONCLUSION

To our knowledge, this is the first review of observational studies to identify indicators of deterioration in young patients with SMI. Worsening cognitive functioning and expressed emotion status could indicate non-adherence and relapse in young patients with SMI but larger sample sizes in good quality studies are needed. The dearth of observational studies means further research is required to ascertain other indicators of deterioration before serious outcomes occur.

Structural Disadvantage and Culture, Race, and Ethnicity in Early Psychosis Services: International Provider Survey

OBJECTIVE

Little is known about provider perspectives on programmatic responses to structural disadvantage and cultural differences within early intervention in psychosis (EIP) services, programs, and models. The primary objective of this study was to investigate providers' perspectives on the impacts of disadvantage and minority race, ethnicity, and culture and to describe current practices and perceived gaps and concerns.

METHODS

An online survey of specialized EIP providers was disseminated in the United Kingdom, United States, Canada, Australia, and Chile. A total of 164 providers, representing 110 unique sites, completed the survey. Closed-ended questions gathered demographic and program data, including information on formal assessment of trauma or adversity, integration of trauma-informed care, integration of formal cultural assessment tools, training focused on culture, programmatic changes to address culture-related issues, and consultation with cultural insiders. Open-ended questions addressed the demographic mix of the program's client population; the perceived role and influence of trauma, structural disadvantage, and cultural differences; and concerns and needs related to these topics. Frequencies were examined for closed-ended items; open-ended responses were systematically coded.

RESULTS

Overall, survey findings suggested low levels of implementation of a variety of assessment and support practices related to cultural diversity in EIP programs. Coding of open-ended responses revealed numerous concerns regarding the impacts of disadvantage and cultural difference on clients and perceived gaps in policy and implementation.

CONCLUSIONS

An expansion of research and service development aimed at better meeting the disadvantage- and culture-related needs of young people with early psychosis and their families should be a priority for the field.

Types, prevalence and gender differences of childhood trauma in first-episode psychosis. What is the evidence that childhood trauma is related to symptoms and functional outcomes in first episode psychosis? A systematic review

This paper reviews and discusses the literature on childhood trauma (CT) in people with first-episode psychosis (FEP). The aim is to update the knowledge on the prevalence and the types of CT suffered by FEP people, to compare them with other samples, to study the impact of gender, and to examine the relationship between CT and symptoms and functional outcomes. We conducted a literature search (1995-2019), to identify reported data on any topic related to CT in FEP samples. The following terms were used in the search: CT or sexual abuse or physical abuse or neglect, and first-episode psychosis. We found 493 studies, of which 68 were included in the review. FEP presented a higher prevalence of CT than controls. Women suffer more sexual abuse. The effect of CT on the severity, the prognosis and the evolution of FEP is unclear. FEP have a high prevalence of CT. Its relationship with symptoms and functional outcomes indicates its importance within treatment. This suggests the importance of creating and implementing specific interventions and personalized therapies addressed to work through their past traumatic experiences to improve their quality of live and their prognosis.

Rate and predictors of interrupted patient follow-up after first-episode psychosis - a retrospective cohort study in France

BACKGROUND

Patient adherence to follow-up after a first episode of psychosis (FEP) is currently a major challenge. Patient's early adherence reduces the risk of relapse and improves their prognosis in the short and long term. The primary goal of our study was to determine the incidence of treatment disengagement at 1-year follow-up in patients with first-episode schizophrenia, schizophreniform or schizoaffective disorder. The secondary goal was to assess the factors associated with treatment disengagement in this patient population.

METHODS

We conducted a monocentric retrospective study of 136 patients in France. Relevant information was collected on sociodemographic, pre-morbidities and co-morbidities data, as well as the management and treatment characteristics at 1.3 and 12 months. Survival analysis was used to assess the association between clinical variables, management and treatment disengagement.

RESULTS

Eighty-four patients (62%) have interrupted their medical follow-up at 1 year, 16% at 1 month and 34% at 3 months. A higher number of out-patient appointments after a FEP was associated with better adherence (HR:0.85 p < .0001 95% IC = [0.0-0.9]). Initial management seems to play an important role. Involuntary admissions (HR:7.14 p = .015 95% IC = [1.48-34.52]) and total number of admissions (HR:6.86 p < .0001 95% IC = [2.47-19.05]) predict disengagement at 1 month while an increased number of out-patient appointments at 3 months predicts adherence (HR:0.60 p < .0001 95% IC = [0.00-0.74]). Being a single parent is associated with disengagement at 3 months (HR:15.51 p = .022 95% IC = [1.49-161.65]).

CONCLUSIONS

Incidence of disengagement is high. It might be necessary to change our management in order to develop out-patient or day-admission care and intensify care for patients at risk.

Better care for less money: cost-effectiveness of integrated care in multi-episode patients with severe psychosis

OBJECTIVE

To compare cost-effectiveness of integrated care with therapeutic assertive community treatment (IC-TACT) versus standard care (SC) in multiple-episode psychosis.

METHOD

Twelve-month IC-TACT in patients with schizophrenia-spectrum and bipolar I disorders were compared with a historical control group. Primary outcomes were entropy-balanced cost-effectiveness based on mental healthcare costs from a payers' perspective and quality-adjusted life years (QALYs) as a measure of health effects during 12-month follow-up.

RESULTS

At baseline, patients in IC-TACT (n = 214) had significantly higher illness severity and lower functioning than SC (n = 56). Over 12 months, IC-TACT had significantly lower days in inpatient (10.3 ± 20.5 vs. 28.2 ± 44.9; P = 0.005) and day-clinic care (2.6 ± 16.7 vs. 16.4 ± 33.7; P = 0.004) and correspondingly lower costs (€-55 084). Within outpatient care, IC-TACT displayed a higher number of treatment contacts (116.3 ± 45.3 vs. 15.6 ± 6.3) and higher related costs (€+1417). Both resulted in lower total costs in IC-TACT (mean difference = €-13 248 ± 2975, P < 0.001). Adjusted incremental QALYs were significantly higher for IC-TACT versus SC (+0.10 ± 0.37, P = 0.05). The probability of cost-effectiveness of IC-TACT was constantly higher than 99%.

CONCLUSION

IC-TACT was cost-effective compared with SC. The use of prima facies 'costly' TACT teams is highly recommended to improve outcomes and save total cost for patients with severe psychotic disorders.

Early Signs Monitoring to Prevent Relapse in Psychosis and Promote Well-Being, Engagement, and Recovery: Protocol for a Feasibility Cluster Randomized Controlled Trial Harnessing Mobile Phone Technology Blended With Peer Support

Background

Relapse in schizophrenia is a major cause of distress and disability and is predicted by changes in symptoms such as anxiety, depression, and suspiciousness (early warning signs [EWSs]). These can be used as the basis for timely interventions to prevent relapse. However, there is considerable uncertainty regarding the implementation of EWS interventions.

Objective

This study was designed to establish the feasibility of conducting a definitive cluster randomized controlled trial comparing Early signs Monitoring to Prevent relapse in psychosis and prOmote Well-being, Engagement, and Recovery (EMPOWER) against treatment as usual (TAU). Our primary outcomes are establishing parameters of feasibility, acceptability, usability, safety, and outcome signals of a digital health intervention as an adjunct to usual care that is deliverable in the UK National Health Service and Australian community mental health service (CMHS) settings. We will assess the feasibility of candidate primary outcomes, candidate secondary outcomes, and candidate mechanisms for a definitive trial.

Methods

We will randomize CMHSs to EMPOWER or TAU. We aim to recruit up to 120 service user participants from 8 CMHSs and follow them for 12 months. Eligible service users will (1) be aged 16 years and above, (2) be in contact with local CMHSs, (3) have either been admitted to a psychiatric inpatient service or received crisis intervention at least once in the previous 2 years for a relapse, and (4) have an International Classification of Diseases-10 diagnosis of a schizophrenia-related disorder. Service users will also be invited to nominate a carer to participate. We will identify the feasibility of the main trial in terms of recruitment and retention to the study and the acceptability, usability, safety, and outcome signals of the EMPOWER intervention. EMPOWER is a mobile phone app that enables the monitoring of well-being and possible EWSs of relapse on a daily basis. An algorithm calculates changes in well-being based on participants’ own baseline to enable tailoring of well-being messaging and clinical triage of possible EWSs. Use of the app is blended with ongoing peer support.

Results

Recruitment to the trial began September 2018, and follow-up of participants was completed in July 2019. Data collection is continuing. The database was locked in July 2019, followed by analysis and disclosing of group allocation.

Conclusions

The knowledge gained from the study will inform the design of a definitive trial including finalizing the delivery of our digital health intervention, sample size estimation, methods to ensure successful identification, consent, randomization, and follow-up of participants, and the primary and secondary outcomes. The trial will also inform the final health economic model to be applied in the main trial.

Unmedicated patients with schizophrenia in economically underdeveloped areas of China

OBJECTIVES

Untreated schizophrenia commonly leads to poor prognosis. The medication treatment rate of schizophrenia patients in economically underdeveloped areas of China has not been well-studied. This study aimed to examine the pattern of unmedicated schizophrenia patients in economically underdeveloped rural and urban areas of China.

METHOD

A total of 4240 schizophrenia patients in Lanzhou (1720 rural and 2520 urban patients) registered in the community mental-health service system in Lanzhou, Gansu province were included. Their socio-demographic and clinical characteristics including medication treatment status were collected and analyzed.

RESULTS

The proportion of unmedicated schizophrenia patients was 22.5% (n = 953) in the whole sample, with 32.3% (556/1720) in rural and 15.8% (397/2520) in urban patients (X²=161.1, P < 0.001). Multiple logistic regression analyses revealed that unmedicated schizophrenia patients in rural area were more likely to be older (OR=1.02, 95%CI: 1.01-1.03), male (OR=1.35, 95%CI: 1.07-1.71), unmarried (OR=0.71, 95%CI: 0.55-0.91), and have lower educational level (OR=0.39, 95%CI: 0.24-0.65), longer illness duration (OR=1.01, 95%CI: 1.00-1.02) and less frequent admissions (OR=0.46, 95%CI: 0.38-0.54). In contrast, unmedicated patients in urban area were more likely to be older (OR=1.01, 95%CI: 1.00-1.02), unmarried (OR=0.77, 95%CI: 0.61-0.98), employed (OR=2.38, 95%CI: 1.87-3.04), and have lower educational level (OR=0.49, 95%CI: 0.37-0.65), better financial status (OR=0.60, 95%CI: 0.48-0.76) and less frequent admissions (OR=0.81, 95%CI: 0.75-0.87).

CONCLUSIONS

The rate of unmedicated schizophrenia patients is high in economically underdeveloped areas of China, particularly in rural areas. Effective policies and measures should be implemented urgently to improve the treatment rate in this population.

Service Use Following First-Episode Schizophrenia Among Commercially Insured Youth

OBJECTIVE

To investigate patterns of mental health service and antipsychotic use following a first-episode schizophrenia (FES) and to examine the role of the treatment setting in which individuals are first diagnosed.

METHOD

Analysis of de-identified administrative claims data from the OptumLabs Data Warehouse was used to identify 1450 privately insured youth and young adults aged 14 through 30 with FES from January 1, 2011 through December 31, 2015. Regression analysis was used to estimate the use of mental health services during the year following FES, by type of service and by site of index diagnosis.

RESULTS

In the year following FES, 79.7% of youth received outpatient mental health services and 35.8% filled a prescription for antipsychotic medication. Among service users, mean outpatient visits were 15.9 and mean antipsychotic fills were 8.3. Youth who received an index diagnosis of FES in an inpatient setting were more likely to fill an antipsychotic medication than youth with FES in other settings. Youth who received an index diagnosis of FES during a specialty mental health outpatient visit had greater use of outpatient mental health than youth who received their diagnosis during a primary care visit.

CONCLUSIONS

Despite evidence-based guidelines supporting outpatient psychosocial care and antipsychotic treatment for FES, one-fifth of this cohort did not use outpatient services and the majority did not fill any prescriptions for antipsychotic medications during the year following FES. Our findings provide renewed urgency to ongoing efforts to accelerate early identification and care coordination for youth with FES.

ENACT: a protocol for a randomised placebo-controlled trial investigating the efficacy and mechanisms of action of adjunctive N-acetylcysteine for first-episode psychosis

BACKGROUND

First-episode psychosis (FEP) may lead to a progressive, potentially disabling and lifelong chronic illness; however, evidence suggests that the illness course can be improved if appropriate treatments are given at the early stages. Nonetheless, the efficacy of antipsychotic medications is suboptimal, particularly for negative and cognitive symptoms, and more efficacious and benign treatments are needed. Previous studies have shown that the antioxidant amino acid N-acetylcysteine (NAC) reduces negative symptoms and improves functioning in chronic schizophrenia and bipolar disorder. Research is scarce as to whether NAC is beneficial earlier in the course of illness. The primary aim of this study is to determine the efficacy of treatment with adjunctive NAC (2 g/day for 26 weeks) compared with placebo to improve psychiatric symptoms in young people experiencing FEP. Secondary aims are to explore the neurobiological mechanisms underpinning NAC and how they relate to various clinical and functional outcomes at 26- and 52-week follow-ups.

METHODS/DESIGN

ENACT is a 26-week, randomised controlled trial of adjunctive NAC versus placebo, with a 26-week non-treatment follow-up period, for FEP. We will be recruiting 162 young people aged 15-25 years who have recently presented to, and are being treated at, the Early Psychosis Prevention and Intervention Centre, Melbourne, Australia. The primary outcome is the Total Score on the Positive and Negative Syndrome Scale which will be administered at baseline, and weeks 4, 8, 12, 26 (primary endpoint), and 52 (end of study). Secondary outcomes include: symptomatology, functioning, quality of life, neurocognition, blood-derived measures of: inflammation, oxidative and nitrosative stress, and magnetic resonance spectroscopy measures of glutathione concentration.

DISCUSSION

Targeted drug development for FEP to date has generally not involved the exploration of neuroprotective agents. This study has the potential to offer a new, safe, and efficacious treatment for people with FEP, leading to better treatment outcomes. Additionally, the neuroprotective dimension of this study may lead to a better long-term prognosis for people with FEP. It has the potential to uncover a novel treatment that targets the neurobiological mechanisms of FEP and, if successful, will be a major advance for psychiatry.

Medication adherence in first episode psychosis: the role of pre-onset subthreshold symptoms

OBJECTIVE

The experience of pre-onset subthreshold psychotic symptoms (STPS, signifying a clinical high-risk state) in first episode psychosis (FEP) predicts poorer outcomes during treatment, possibly through differential adherence to medication. We explored whether adherence differs between FEP patients with and without pre-onset STPS.

METHODS

Antipsychotic medication adherence was compared in 263 STPS+ and 158 STPS- subjects in a specialized early intervention program for FEP. Data were gathered from a larger observational study conducted between 2003 and 2016. STPS status, sociodemographic, and baseline clinical variables were tested as predictors of non-adherence using univariate and multivariate logistic regressions. Time to onset of non-adherence was analyzed using Kaplan-Meier curves. The same predictors were tested as predictors of time to onset of non-adherence using Cox regression models.

RESULTS

Medication non-adherence was higher in STPS+ participants (78.9% vs. 68.9%). STPS status (OR 1.709), substance use disorder (OR 1.767), and milder positive symptoms (OR 0.972) were significant baseline predictors of non-adherence. Substance use disorder (HR 1.410), milder positive symptoms (HR 0.990), and lack of contact between the clinical team and relatives (HR 1.356) were significant baseline predictors of time to non-adherence.

CONCLUSION

FEP patients who experience pre-onset STPS are more likely to be non-adherent to antipsychotic medication over 2 years of intervention. FEP programs should routinely evaluate pre-onset symptomatology to deliver more personalized treatments, with emphasis on engaging both patients and family members from the beginning of care.

Impact of tobacco, alcohol and cannabis use on treatment outcomes among patients experiencing first episode psychosis: Data from the national RAISE-ETP study

AIM

The primary aim of this study was to examine the effect of recent tobacco, alcohol and cannabis use on treatment outcomes among participants experiencing first episode psychosis (FEP).

METHODS

Secondary data analyses were conducted on 404 participants enrolled in the Recovery After an Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP) study. RAISE-ETP investigated the effectiveness of a coordinated specialty care (CSC) intervention for FEP in community mental health agencies in the United States. Generalized estimating equations were used to examine whether recent tobacco smoking, alcohol, and cannabis use at baseline were associated with illness severity, number of antipsychotic pills missed, psychiatric symptoms and quality of life during the 24-month treatment period, after controlling for duration of untreated psychosis and treatment group.

RESULTS

At baseline, roughly 50% (n = 209) of participants reported recent tobacco, 28% (n = 113) alcohol and 24% (n = 95) cannabis use. Tobacco smokers had higher levels of illness severity (β = .24; P < .005), a higher number of missed pills (β = 2.89; P < .05), higher psychiatric symptoms and lower quality of life during treatment relative to non-smokers. Alcohol users had a higher number of missed pills (β = 3.16; P < .05) during treatment and cannabis users had higher levels of illness severity (β = .18; P < .05) and positive symptoms (β = 1.56; P < .05) relative to non-users.

CONCLUSIONS

Tobacco, alcohol and cannabis use are common in youth seeking treatment for FEP. Tobacco smoking was associated with more negative clinical outcomes. These findings have implications for including interventions targeting these areas of substance use within current CSC models.

Reduction of Involuntary Admissions in Patients With Severe Psychotic Disorders Treated in the ACCESS Integrated Care Model Including Therapeutic Assertive Community Treatment

Objective: The ACCESS treatment model offers assertive community treatment (ACT) embedded in an integrated care program to patients with severe psychotic disorders. Compared to standard care, it proved to be more effective in terms of service disengagement and other outcomes in patients with psychotic disorders over 12, 24, and 48 months. Many patients with severe mental disorders experience involuntary admissions which can be potentially traumatic. In this study, we assessed the effect of ACT on reducing involuntary admissions over an observation period of 4 years. Method: One hundred seventy-one patients treated in ACCESS were included in this study. The primary outcome was rate of involuntary admissions during 48 months. Secondary outcomes were differences between those with and without involuntary admissions in the 2 years prior to ACCESS regarding change of psychopathology, severity of illness, psychosocial functioning, quality of life, satisfaction with care, medication non-adherence, and service-disengagement. Results: Of 171 patients, 58 patients (33.9%) were involuntarily admitted to hospital in the past 2 years before entry. During the 4 years of treatment, 16 patients (9.4%) were involuntarily admitted to hospital which was a significantly lower rate compared to the 2 years before inclusion in ACCESS (p < .001). Comparing the two groups, larger improvements in severity of illness (p = .004) and functional status (p = .043) were detected in the group with no history of involuntary admissions. At 4-year follow-up, of the remaining patients, 69.2% (n = 81) were full adherent (p < .001), compared to 18.9% (n = 31) at baseline with no differences between the two groups over the study period (p = .25). Over 4 years, only 13 patients (13.2%) were service-disengaged due to non-practical reasons. Conclusions: In this long-term study, we were able to demonstrate a reduction in involuntary admissions in four treatment years compared to the 2 years prior to admission to the ACCESS model in patients with severe and mostly multiphase schizophrenia spectrum disorders and affective disorders with psychotic features. This may help prevent patients from suffering from a potentially traumatic experience during treatment in the psychiatric system.

Medication adherence in first-episode psychosis and its association with psychopathology

BACKGROUND

The purpose of the study was to follow-up the individuals with first-episode psychosis (FEP) for a period of 1 year to assess their medication adherence rates and to identify the association between medication adherence and psychopathology.

MATERIALS AND METHODS

In a 1 year longitudinal study, 59 individuals with FEP were assessed for their sociodemographic profile and medication adherence at 1 month and 12-month follow-up period using a semi-structured per forma. Positive and negative symptoms were assessed by positive and negative syndrome scale (PANSS) while the functioning by global assessment of functioning (GAF) scale.

RESULTS

Nearly 85% of the individuals were adherent with medications during the 1-month follow-up period, 32.2% were poorly adherent at the end of 12 months. Among various factors examined for association with medication adherence, positive and negative symptoms, and global functioning of the individuals at the end of 12 months were found to significant associated with poor medication adherence.

CONCLUSION

There is a high rate of medication nonadherence in individuals with FEP at 12-month follow-up, and factors affecting nonadherence should be addressed specifically to improve medication adherence in these individuals.

Impact of comprehensive treatment for first episode psychosis on substance use outcomes: A randomized controlled trial

Lifetime co-occurring substance use disorders are common at the time of presentation for treatment of a first episode of primary psychosis and persistent substance use disorder (SUD) leads to poorer outcomes. We assessed whether the NAVIGATE program, a coordinated specialty care service that includes optional substance abuse content reduced substance use compared to usual care in 404 individuals in the Recovery After Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP) study. Participants were randomized to two years of NAVIGATE (n = 223) or usual care (n = 181) and assessed monthly for substance use. At baseline, over one-half (51.7%) of the participants met criteria for a lifetime SUD, including over one-third with alcohol use disorder (36.4%) and with cannabis use disorder (34.7%). Contrary to our hypothesis, there was no treatment group by time interaction effect on days of self-reported substance use over the two-year follow-up. Participant exposure to the substance abuse component of the NAVIGATE program was low, suggesting that modifications to the program and training method for clinicians may be needed. Further research is needed to determine the most effective strategies for addressing substance use disorders in persons recovering from a first episode of psychosis.

First-episode psychosis: Ongoing mental health service utilization during the stable period for adolescents

AIM

The timely identification and treatment of psychosis are increasingly the focus of early interventions, with research targeting the initial high-risk period in the months following first-episode hospitalization. Ongoing treatment after stabilization is also essential in the years following a first-episode psychosis (FEP), but has received less research attention. In this study, variables that could impact continued psychiatric service utilization by adolescents following their FEP and temporal patterns in service utilization are examined.

METHODS

Families of 52 adolescents (aged 14.4 ± 2.5 years) discharged following a hospitalization for FEP were contacted two or more years following the adolescents' discharge. A chart review (Time 1) of hospital records provided clinical data on each adolescent's psychiatric diagnosis, symptoms, illness course, medications and family history. Follow-up (Time 2) data were collected from parents/caregivers using a questionnaire enquiring about post-discharge treatment history and service utilization.

RESULTS

Bivariate analyses were conducted to identify Time 1 variables associated with psychiatric service utilization at Time 2. Significant variables were included in a logistic regression model and three variables were independently associated with continued service utilization: having a primary diagnosis of schizophrenia (odds ratio (OR) = 24.0; P = 0.02), not having a first-degree relative with depression (OR = 0.12; P = 0.05) and fewer months since the last inpatient discharge (OR = 0.92; P = 0.02).

CONCLUSIONS

Findings suggest: (1) the importance of early diagnosis, (2) that a relative with depression may negatively influence the adolescent's ongoing service utilization, and (3) that 18 months post-discharge may be a critical time to review treatment strategies and collaborate with youth and families to ensure appropriateness of services.

Effectiveness of integrated care including therapeutic assertive community treatment in severe schizophrenia-spectrum and bipolar I disorders: Four-year follow-up of the ACCESS II study

The ACCESS-model offers integrated care including assertive community treatment to patients with psychotic disorders. ACCESS proved more effective compared to standard care (ACCESS-I study) and was successfully implemented into clinical routine (ACCESS-II study). In this article, we report the 4-year outcomes of the ACCESS-II study. Between May 2007 and December 2013, 115 patients received continuous ACCESS-care. We hypothesized that the low 2-year disengagement and hospitalization rates and significant improvements in psychopathology, functioning, and quality of life could be sustained over 4 years. Over 4 years, only 10 patients disengaged from ACCESS. Another 23 left for practical reasons and were successfully transferred to other services. Hospitalization rates remained low (13.0% in year 3; 9.1% in year 4). Involuntary admissions decreased from 35% in the 2 years prior to ACCESS to 8% over 4 years in ACCESS. Outpatient contacts remained stably high at 2.0–2.4 per week. We detected significant improvements in psychopathology (effect size d = 0.79), illness severity (d = 1.29), level of functioning (d = 0.77), quality of life (d = 0.47) and stably high client satisfaction (d = 0.02) over 4 years. Most positive effects were observed within the first 2 years with the exception of illness severity, which further improved from year 2 to 4. Within continuous intensive 4-year ACCESS-care, sustained improvements in psychopathology, functioning, quality of life, low service disengagement and re-hospitalization rates, as well as low rates of involuntary treatment, were observed in contrast to other studies, which reported a decline in these parameters once a specific treatment model was stopped. Yet, stronger evidence to prove these results is required.

Early intervention in psychosis: clinical aspects of treatment

Engaging patients in first-episode psychosis services is critical in maximising the effect of early intervention and establishing a framework for longer-term treatment. Biopsychosocial assessments determine a working diagnosis and inform evidence-based treatment. Atypical antipsychotics should be used at doses that maximise therapeutic benefit and adherence while minimising side-effects. Patients are helped to construct a narrative of their illness, including a shared understanding of the contribution of biological and environmental risks, and early warning signs. Common comorbid conditions, including depression, suicidal ideation, substance misuse and anxiety, should be addressed. Management of comorbid borderline and antisocial personality disorders is difficult; their nexus with psychosis is discussed. Cognitive–behavioural therapy is a mainstay of treatment, with specific interventions developed for problems typical in first-episode presentations. Core psychosocial interventions include psychoeducation, vocational and educational support, family interventions and multimodal group programmes.

Effect of continued cannabis use on medication adherence in the first two years following onset of psychosis

Uncertainty exists whether the use of non-prescription psychoactive substances following onset of a first episode of psychosis (FEP), in particular cannabis use, affects medication adherence. Data from FEP patients (N=233) obtained through prospective assessments measured medication adherence and pattern of cannabis and other substance use in the first two years following onset of psychosis. Multiple logistic regression analyses were employed to compare the different substance use groups with regard to risk of medication non-adherence, while controlling for confounders. The proportion of non-adherent patients was higher in those who continued using high-potency forms of cannabis (skunk-like) following the onset (83%) when compared to never regular users (51%), corresponding to an Odds Ratio (OR) of 5.26[95% Confidence Interval (CI) 1.91-15.68]. No significant increases in risk were present in those who used cannabis more sporadically or used milder forms of cannabis (hash-like). Other substances did not make an independent contribution in this model, including cigarette use ([OR 0.88, 95% CI 0.41-1.89]), alcohol use ([OR 0.66, 95% CI 0.27-1.64]) or regular use of other illicit drugs ([OR 1.03, 95% CI 0.34-3.15]) following the onset. These results suggest that continued use of high-potency cannabis following the onset of psychosis may adversely affect medication adherence.

Predictors of favourable outcome in young people with a first episode psychosis without antipsychotic medication

INTRODUCTION

Data from the literature suggests that some first episode psychosis (FEP) patients may recover without antipsychotic medication. There is however no reliable way to identify them. In a previous paper we found, in a cohort of 584 FEP patients, that those consistently refusing medication had poorer pre-morbid functioning, less insight, higher rate of substance use and poorer outcome. However, some medication refusers, had a favourable outcome. The study aim was to identify predictors of good short term outcome despite non-exposure to medication.

METHODS

The Early Psychosis Prevention and Intervention Centre (EPPIC) admitted 786 FEP patients between 1998 and 2000. Data were collected from patients' files using a standardized questionnaire. Data on medication adherence was available in 584 patients. Among the 17.9% of patients who consistently refused medication over the entire treatment phase we compared patients who had a favourable symptomatic and functional outcome with those who did not.

RESULTS

Among patients who consistently refused medication, 41% achieved symptomatic remission and 33% reached functional recovery. Predictors of symptomatic remission were a better premorbid functioning level, higher education and employment status at baseline. Predictors of functional recovery were a shorter duration of the prodrome phase, less severe psychopathology at baseline and lower cannabis use.

CONCLUSIONS

Despite limitations mainly linked to the fact that non-exposure to antipsychotic medication was based on patient's treatment refusal, this study identified some characteristics which may contribute to the identification of a sub-group of FEP patients who may have good short term outcome without antipsychotic treatment.

The Positive and Negative Experiences of Caregiving for Siblings of Young People with First Episode Psychosis

Background: The impact of first episode psychosis (FEP) upon parents’ experience of caregiving has been well-documented. However, the determinants and nature of this remain poorly understood in siblings. It is hypothesized that siblings of young people with FEP are also impacted by caregiving and burden. This study aimed to characterize the experience of caregiving for siblings of young people with FEP.

Method: Survey methodology was used to explore the experience of 157 siblings in the first 18 months of their brother or sister’s treatment for FEP. Participants reported on their appraisal of the negative and positive aspects of caregiving as measured by the Experience of Caregiving Inventory (ECI). Descriptive statistics were used to establish the results for the total sample as well as for gender and birth order differences. A series of multivariate regression analyses were conducted to determine the relationships between illness characteristics and siblings’ experience of caregiving.

Results: Older brothers reported the lowest scores for negative experiences in caregiving and younger sisters reported the highest. Negative experiences in caregiving resulted in less warmth within the sibling relationship and impacted negatively upon quality of life. When the young person with FEP had attempted suicide and/or been physically violent, siblings experienced more caregiver burden. Multivariate analysis showed that female gender was a significant factor in explaining the impact of illness related variables on the experience of caregiving.

Conclusion: Suicide attempts and a history of violence resulted in higher caregiving burden for siblings regardless of whether they lived with the young person experiencing FEP or not. Female siblings are at higher risk of negative experiences from caregiving resulting in a reduced quality of life and a changed sibling relationship. Suicide attempts and violence are indicators for intensive case management to improve outcomes for the individual with FEP which may in turn reduce the burden experienced by the sibling. Clinicians can use these findings to identify siblings, assertively intervene and provide increased psychological support, psychoeducation and practical problem solving to reduce the burden. The caregiving role that they already play for their ill brother or sister should be recognized.

Five-fold increased risk of relapse following breaks in antipsychotic treatment of first episode psychosis

BACKGROUND

A key problem in the management of first episode psychosis is that patients are often reluctant to take antipsychotic medication, especially once their presenting symptoms have resolved. Clinicians may be tempted to trial a 'break in treatment' in such patients.

AIM

To assess the impact of interruptions in the antipsychotic treatment of first episode psychosis.

METHOD

Treatment adherence and clinical course were assessed during the 18months following presentation in 136 consecutive patients with a first episode of psychosis in 2003-2005 by a systematic retrospective casenote review. Regression analyses were used to examine the time to remission and the risk of relapse in patients who had stopped antipsychotics for one month or more.

RESULTS

There were breaks in antipsychotic treatment of ≥1month in more than half of the patients (n=73; 58%). When these occurred before they had recovered (n=22; 17%), the time to remission was almost twice as long as in patients in whom treatment was continuous (t=2.9, P=0.01). Patients in whom treatment was interrupted were 5 times more likely to have relapsed than those in whom it was continuous (p=0.0001, 95%CI 2.1-11). The mean time to relapse following an interruption in treatment was 3months.

CONCLUSION

If the treatment of first episode psychosis with antipsychotic medication is stopped for a month or more, remission may be delayed and the risk of relapse following remission may be substantially increased.

Acceptance and Efficacy of Metacognitive Training (MCT) on Positive Symptoms and Delusions in Patients With Schizophrenia: A Meta-analysis Taking Into Account Important Moderators

Metacognitive training (MCT) is a new, widely used intervention for psychosis. The present meta-analysis examines the efficacy of MCT in schizophrenia. Fifteen studies comparing effects of MCT on positive symptoms, delusions or acceptance of MCT with a control group were included in this meta-analysis. These studies comprised a total of 408 patients in the MCT condition and 399 in the control condition. The moderating effects of masking of outcome assessment, randomization, incomplete outcome data, use of an active control intervention, and individual vs group MCT were investigated. Possible effects of sensitivity analyses and publication bias were also examined. The results show a significant overall effect of MCT for positive symptoms (g = -0.34, 95% CI [-0.53, -0.15]), delusions (g = -0.41, 95% CI [-0.74, -0.07]) and acceptance of the intervention (g = -0.84, 95% CI [-1.37, -0.31]). Using only studies being at low risk for bias regarding randomization, masking and incomplete outcome data reduced effect sizes for positive symptoms and delusions (g = -0.28, 95% CI [-0.50, -0.06] and g = -0.18, 95% CI [-0.43, 0.06]), respectively. This meta-analysis demonstrates that MCT exerts a small to moderate effect on delusions and positive symptoms and a large effect on acceptance of the intervention. The effect on delusions is reduced, but remains significant when potential biases are considered.

Duration of untreated psychosis: Impact of the definition of treatment onset on its predictive value over three years of treatment

BACKGROUND

While reduction of DUP (Duration of Untreated Psychosis) is a key goal in early intervention strategies, the predictive value of DUP on outcome has been questioned. We planned this study in order to explore the impact of three different definition of "treatment initiation" on the predictive value of DUP on outcome in an early psychosis sample.

METHODS

221 early psychosis patients aged 18-35 were followed-up prospectively over 36 months. DUP was measured using three definitions for treatment onset: Initiation of antipsychotic medication (DUP1); engagement in a specialized programme (DUP2) and combination of engagement in a specialized programme and adherence to medication (DUP3).

RESULTS

10% of patients never reached criteria for DUP3 and therefore were never adequately treated over the 36-month period of care. While DUP1 and DUP2 had a limited predictive value on outcome, DUP3, based on a more restrictive definition for treatment onset, was a better predictor of positive and negative symptoms, as well as functional outcome at 12, 24 and 36 months. Globally, DUP3 explained 2 to 5 times more of the variance than DUP1 and DUP2, with effect sizes falling in the medium range according to Cohen.

CONCLUSIONS

The limited predictive value of DUP on outcome in previous studies may be linked to problems of definitions that do not take adherence to treatment into account. While they need replication, our results suggest effort to reduce DUP should continue and aim both at early detection and development of engagement strategies.

Recommendations for the optimal care of patients with recent-onset psychosis in the Asia-Pacific region

Providing optimal care to patients with recent-onset psychosis can improve outcomes and reduce relapse. However, there is a lack of consistency of the implementation of guidelines for such patients across the Asia-Pacific region. We determined a pragmatic set of recommendations for use on a day-to-day basis to help provide optimal care at this crucial stage of illness. The recommendations were developed over a series of meetings by an international faculty of 15 experts from the Asia-Pacific region, Europe, and South Africa. A structured search of the PubMed database was conducted. This was further developed based on the faculty's clinical experience and knowledge of the literature into 10 key aspects of optimal care for patients during the first five years of a diagnosis of a psychotic disorder, with particular relevance to the Asia-Pacific region. Several common principles emerged: adherence to antipsychotic medications is crucial; substance abuse, psychiatric and medical comorbidities should be addressed; psychosocial interventions play a pivotal role; and family members can play a vital role in overall patient care. By following these recommendations, clinicians may improve outcomes for patients with recent-onset psychosis.

Substance use, medication adherence and outcome one year following a first episode of psychosis

Both substance use and poor medication adherence are associated with poor outcome in psychosis. To clarify the contributions of substance use and poor medication adherence to poor outcome in the year following a first episode of psychosis, 205 patients were evaluated for use of tobacco, alcohol, cannabis and stimulants at their psychosis onset, and in a 1-year follow-up. Data on medication adherence and symptom remission were also collected. Patients had high rates of overall substance use before (37-65%) and after psychosis onset (45-66%). 44% showed poor medication adherence and 55% did not reach remission from psychosis. Nicotine dependence and cannabis use after psychosis onset significantly predicted both poor medication adherence and non-remission, and poor medication adherence mediated the effects of these substances on non-remission. In conclusion, medication adherence lies on the causal pathway between nicotine dependence and cannabis on the one hand and non-remission on the other.

Nonadherence to antipsychotics: the role of positive attitudes towards positive symptoms

Approximately 50-75% of all patients do not take their antipsychotic medication as prescribed. The current study examined reasons why patients continue versus discontinue antipsychotic medication. We were particularly interested to which extent positive attitudes towards psychotic symptoms foster medication nonadherence. An anonymous online questionnaire was set up to decrease response biases. After a strict selection process, 91 participants with schizophrenia spectrum disorders were retained for the final analyses. On average, 6.2 different reasons for nonadherence were reported. Side-effects (71.4%), sudden subjective symptom improvement (52.4%) and forgetfulness (33.3%) emerged as the most frequent reasons for drug discontinuation. Approximately one fourth of all participants (27.3%) reported at least one positive aspect of psychosis as a reason for nonadherence. In contrast, patients reported on average 3.5 different reasons for adherence (e.g., want to live a normal life (74.6%) and fear of psychotic symptoms (49.3%)). The belief that paranoia represents a survival strategy (subscale derived from the Beliefs about Paranoia Scale) was significantly associated with nonadherence. Patients' attitudes toward medication and the individual illness model need to be carefully considered when prescribing medication. In particular for patients who are likely to discontinue psychopharmacological treatment complementary or alternative psychological treatment should be sought because of a largely increased risk of relapse in the case of sudden drug discontinuation.

Forgotten family members: the importance of siblings in early psychosis

OBJECTIVE

This paper reviews the evidence on the significance of sibling inclusion in family interventions and support during early psychosis.

METHOD

This narrative review presents the current research related to the importance of family work during early psychosis, the needs and developmental significance of siblings during adolescence and early adulthood, the protective effects of sibling relationships, and the characteristics of early psychosis relevant to the sibling experience. It will also review the evidence of the sibling experience in chronic physical illness and disability, as well as long-term psychotic illness.

CONCLUSIONS

Despite the evidence that working with families is important during early psychosis, siblings have been largely ignored. Siblings are an important reciprocal relationship of long duration. They play an important role in development during adolescence and early adulthood. These relationships may be an underutilized protective factor due to their inherent benefits and social support. Developmental theories imply that early psychosis could negatively impact the sibling relationship and their quality of life, effecting personality development and health outcomes. The evidence shows that adolescent physical illness or disability has a significantly negative impact on the sibling's quality of life and increases the risk for the onset of mental health issues. Long-term psychotic illness also results in negative experiences for siblings. Current evidence shows that siblings in early psychosis experience psychological distress and changes in functional performance. Further research using standard measures is required to understand the impact early psychosis has on the sibling relationship and their quality of life.

Long-acting atypical antipsychotics: characterization of the local tissue response

Purpose

Long-acting injectables (LAIs) are increasingly recognized as an effective therapeutic approach for treating chronic conditions. Many LAIs are formulated to create a poorly soluble depot from which the active agent is delivered over time. This long residing depot can cause localized chronic-active inflammation in the tissue, which has not been well defined in the literature. The purpose of this work is to establish an experimental baseline for describing these responses.

Methods

Non-human primates and rodents were used to examine the response to LAI formulations of two clinically relevant atypical antipsychotics, aripiprazole monohydrate and olanzapine pamoate monohydrate.

Results

A foreign body response develops with elevations of key cytokines such as IL-1α, IL-1β, TNFα, and IL6 at the site of injection. However, the tissue response for the two atypical antipsychotics compounds diverge as evidenced by quantitative differences observed in cytokine levels at various time points after dosing.

Conclusions

Our studies show that, while the drugs are in the same therapeutic class, the response to each of these compounds can be distinguished qualitatively and quantitatively, supporting the idea that the injection site reaction involves a multiplicity of factors including the properties of the compound and cellular dynamics at the site of injection.

Drug attitude in adolescents: a key factor for a comprehensive assessment

OBJECTIVE

Very few studies have evaluated the subjective experience (SE) in children and adolescents treated with antipsychotics. The present study aimed to evaluate the SE of antipsychotics in adolescents diagnosed with different psychiatric conditions and to identify explanatory variables of adolescents' SE and compliance with treatment.

METHODS

The Drug Attitude Inventory (DAI) was used to evaluate SE in 67 adolescents in 2 different countries (Italy and United Kingdom). Compliance was measured using a Likert scale completed by both patients and parents. To evaluate other parameters correlated to the SE, the following scales were administered: Clinical Global Impression Scale, Children's Global Assessment Scale, Extrapyramidal Symptoms Rating Scale, Barnes Akathisia Rating Scale, and EuroQoL (for quality of life). Multiple and logistic regression analyses were applied.

RESULTS

No significant difference in drug attitude was found between psychotic and nonpsychotic patients. Our results showed a highly significant association between DAI and compliance (Spearman index, 0.33; P = 0.005); for all other variables, DAI associated significantly only with quality of life (r = 0.25; P = 0.03). The multivariable analysis confirmed the presence of a strong association between compliance and DAI (P = <0.001). In our sample, drug attitude was the only variable found to be correlated with the compliance, whereas extrapyramidal adverse effects showed an only marginally significant association.

CONCLUSIONS

Our observations provide confirmation, also in adolescents, that drug attitude is strongly correlated with treatment compliance and underline the need in clinical assessments to always consider the patient's viewpoint.

Cannabis use and involuntary admission may mediate long-term adherence in first-episode psychosis patients: a prospective longitudinal study

BACKGROUND

This study aimed to examine factors associated with treatment adherence in first-episode psychosis (FEP) patients followed up over 8 years, especially involuntary first admission and stopping cannabis use.

METHODS

This prospective, longitudinal study of FEP patients collected data on symptoms, adherence, functioning, and substance use. Adherence to treatment was the main outcome variable and was categorized as 'good' or 'bad'. Cannabis use during follow-up was stratified as continued use, stopped use, and never used. Bivariate and logistic regression models identified factors significantly associated with adherence and changes in adherence over the 8-year follow-up period.

RESULTS

Of the 98 FEP patients analyzed at baseline, 57.1% had involuntary first admission, 74.4% bad adherence, and 52% cannabis use. Good adherence at baseline was associated with Global Assessment of Functioning score (p = 0.019), Hamilton Depression Rating Scale score (p = 0.017) and voluntary admission (p < 0.001). Adherence patterns over 8 years included: 43.4% patients always bad, 26.1% always good, 25% improved from bad to good. Among the improved adherence group, 95.7% had involuntary first admission and 38.9% stopped cannabis use. In the subgroup of patients with bad adherence at baseline, involuntary first admission and quitting cannabis use during follow up were associated with improved adherence.

CONCLUSIONS

The long-term association between treatment adherence and type of first admission and cannabis use in FEP patients suggest targets for intervention to improve clinical outcomes.

Gender differences in first episode psychotic mania

BACKGROUND

The aim of this paper was to delineate the impact of gender on premorbid history, onset, and 18 month outcomes of first episode psychotic mania (FEPM) patients.

METHODS

Medical file audit assessment of 118 (male = 71; female = 47) patients with FEPM aged 15 to 29 years was undertaken on clinical and functional measures.

RESULTS

Males with FEPM had increased likelihood of substance use (OR = 13.41, p <.001) and forensic issues (OR = 4.71, p = .008), whereas females were more likely to have history of sexual abuse trauma (OR = 7.12, p = .001). At service entry, males were more likely to be using substances, especially cannabis (OR = 2.15, p = .047), had more severe illness (OR = 1.72, p = .037), and poorer functioning (OR = 0.96, p = .045). During treatment males were more likely to decrease substance use (OR = 5.34, p = .008) and were more likely to be living with family (OR = 4.30, p = .009). There were no gender differences in age of onset, psychopathology or functioning at discharge.

CONCLUSIONS

Clinically meaningful gender differences in FEPM were driven by risk factors possibly associated with poor outcome. For males, substance use might be associated with poorer clinical presentation and functioning. In females with FEPM, the impact of sexual trauma on illness course warrants further consideration.

Differentiating schizoaffective and bipolar I disorder in first-episode psychotic mania

OBJECTIVE

This study aims to differentiate schizoaffective disorder (SAD) and bipolar-I-disorder (BD) in first-episode psychotic mania (FEPM).

METHODS

All 134 patients from an epidemiological first-episode psychosis cohort (N=786) with FEPM and an 18-month follow-up final diagnosis of SAD (n=36) or BD (n=98) were assessed with respect to pre-treatment, baseline and outcome differences. Second, patients with baseline BD who shifted (shifted BD) or did not shift to SAD (stable BD) over the follow-up period were compared regarding pre-treatment and baseline differences.

RESULTS

SAD patients displayed a significantly longer duration of untreated psychosis (DUP; effect size r=0.35), a higher illness-severity at baseline (r=0.20) and more traumatic events (Cramer-V=0.19). SAD patients displayed a significantly higher non-adherence rate (Cramer-V=0.19); controlling for time in treatment and respective baseline scores, SAD patients had significantly worse illness severity (CGI-S; partial η²=0.12) and psychosocial functioning (GAF; partial η(2)=0.07) at 18-months, while BD patients were more likely to achieve remission of positive symptoms (OR=4.9, 95% CI=1.8-13.3; p=0.002) and to be employed/occupied (OR=7.7, 95% CI=2.4-24.4, p=0.001). The main discriminator of stable and shifted BD was a longer DUP in patients shifting from BD to SAD.

CONCLUSIONS

It is difficult to distinguish BD with psychotic symptoms and SAD in patients presenting with FEPM. Longer DUP is related to SAD and to a shift from BD to SAD. Compared to BD, SAD had worse outcomes and higher rates of non-adherence with medication. Despite these differences, both diagnostic groups need careful dimensional assessment and monitoring of symptoms and functioning in order to choose the right treatment.

Impact of symptom resolution on medication adherence in first episode psychosis

Adequate adherence to medication confers benefits on patients with psychotic illness, but is difficult to achieve. Efficacy of medication influences adherence in patients in advanced phases of illness and may have a similar influence on patients with a first episode of psychosis (FEP). We assessed medication adherence and efficacy in 216 FEP patients at program entry and at 3 and 6 months later. "Efficacy" was evaluated as the ability of medication to reduce positive or negative symptoms to below established thresholds for clinical remission at each evaluation. Adherence was defined as adequate (>75%) or not. Resolution of negative symptoms by month 3 of treatment was associated with inadequate adherence at months 3 and 6. In contrast, rapid resolution of positive symptoms showed no relationship to adherence. In a multivariate analysis taking into account other determinants of adherence in FEP, the role of early negative symptom remission was confirmed, and we found that a 3-month sustained remission of positive symptoms was associated with adequate adherence. Medication efficacy may promote adherence if it produces sustained remission of positive symptoms. However, many patients who benefit from medication, particularly those with rapid improvement of negative symptoms, fail to adhere to the treatment.

Depressive symptoms in first episode schizophrenia spectrum disorder

BACKGROUND

Depressive symptoms in 'non-affective' first episode schizophrenia spectrum disorders (FES) are common, but poorly understood, resulting in a range of conceptual and clinical management issues. This study had three aims: (i) to determine the prevalence of moderate to severe depressive symptoms (defined as a Clinical Global Impressions Scale-Bipolar Disorder (CGI-BP depression) score >3) in a large representative sample of FES patients; (ii) to compare the clinical and functional characteristics of FES patients with and without these depressive symptoms at service entry; and (iii) to compare the characteristics of FES patients with and without persistent depressive symptoms.

METHODS

Medical file audit methodology was employed to collect information on 405 patients with FES treated at the Early Psychosis Prevention and Intervention Centre (EPPIC), Melbourne, Australia.

RESULTS

26.2% (n=106) of the patients had moderate to severe depression at service entry. At service entry and at discharge, those with depressive symptoms had greater insight into their illness but did not differ from those without depressive symptoms in terms of severity of overall psychopathology. Substance use was significantly less common in those with depressive symptoms at service entry and at discharge. Of those who were depressed at baseline, 14.2% (n=15) continued to have moderate to severe depressive symptoms at discharge.

DISCUSSION

Depressive symptoms are common in patients with FES. Understanding the nature and characteristics of depression in FES has important clinical implications for both early intervention and treatment.

Duration of untreated psychosis: a proposition regarding treatment definition

AIM

Duration of untreated psychosis (DUP) refers to the time elapsing between psychosis onset and treatment initiation. Despite a certain degree of consensus regarding the definition of psychosis onset, the definition of treatment commencement varies greatly between studies and DUP may be underestimated due to lack of agreement. In the present study, three sets of criteria to define the end of the untreated period were applied in a first-episode psychosis cohort to assess the impact of the choice of definition on DUP estimation.

METHODS

The DUP of 117 patients admitted in the Treatment and Early Intervention in Psychosis Program Psychosis in Lausanne was measured using the following sets of criteria to define treatment onset: (i) initiation of antipsychotic medication; (ii) entry into a specialized programme; and (iii) entry into a specialized programme and adequate medication with a good compliance.

RESULTS

DUP varied greatly according to definitions, the most restrictive criteria leading to the longest DUP (median DUP1=2.2 months, DUP2=7.4 months and DUP3=13.6 months). A percentage of 19.7 of the patients who did not meet these restrictive criteria had poorer premorbid functioning and were more likely to use cannabis. Longer DUP3 was associated with poorer premorbid functioning and with younger age at onset of psychosis.

CONCLUSION

These results underline the need for a unique and standardized definition of the end of DUP. We suggest that the most restrictive definition of treatment should be used when using the DUP concept in future research.

Mental capacity and consent to treatment in psychiatric patients: the state of the research

PURPOSE OF REVIEW

The past three decades have seen the emergence of the field of decision-making capacity research. The growth has been such that there are several reviews covering a variety of subtopics within the field. The goal is to briefly summarize the state of research.

RECENT FINDINGS

Most studies in this field use the MacArthur Competence Assessment Tools for the decisional capacity assessment. Studies in psychiatric patients indicate incapacity is common (20-30%), but the majority are capable of making treatment decisions. Positive symptoms (hallucinations, delusions); negative symptoms (unusual thought content, conceptual disorganization); severity of symptoms; involuntary admission; lack of insight and treatment refusal were the stronger predictors for incapacity in acute and cognitive dysfunction in chronic patients.

SUMMARY

Mental capacity has complex relationships with psychopathological variables, and these relationships are different according to diagnostic group. More research is needed to determine the clinical parameters related to the lack of capacity to make treatment decisions in psychiatric patients.

Reconceptualizing medication adherence: six phases of dynamic adherence

Nonadherence is the Achilles' heel of effective psychiatric treatment. It affects the resolution of mental health symptoms and interferes with the assessment of treatment response. The meaning of the term adherence has evolved over time and is now associated with a variety of definitions and measurement methods. The result has been a poorly operationalized and nonstandardized term that is often interpreted differently by providers and patients. Drawing extensively from the literature, this article aims to (1) describe changes in the concept of adherence, drawing from the mental health treatment literature, (2) present a more comprehensive definition of adherence that recognizes the role of patient-provider transactions, (3) introduce dynamic adherence, a six-phase model, which incorporates the role of transactional processes and other factors that influence patients' adherence decisions, and (4) provide recommendations for providers to improve adherence as well as their relationships with patients.
