    Aim There is an ongoing debate regarding the optimal timing of discontinuation of antipsychotic drugs for patients with first episode psychosis. Although most guidelines recommend maintenance therapy for at least 1 or 2 years after reaching remission, study results indicate that early discontinuation may be beneficial for at least a subsample of patients. To date, little is known about which medication strategies are applied in patients recovering from a first psychotic episode. In this study, we examined the beliefs and practices of clinicians on medication discontinuation. Methods We performed a survey among 50 experienced Dutch psychiatrists to assess how often specific treatment strategies have been applied in the past 12 months, as well as their knowledge and expectations with respect to medication discontinuation. Results Psychiatrists estimated that, after remission, they continued medication at the same dose for at least 12 months in 51.2% of cases, continued in a reduced dose in 33.8% of cases and discontinued medication in 9.1% of cases after 4.4 months of remission on average. Although the medication is discontinued in only a relatively small proportion of patients, almost half of all clinicians (45.9%) used this strategy at least once in the past 12 months. Conclusions There is substantial practice variation in antipsychotic medication strategies after remission from a first psychotic episode. Future research on long-term effects of early medication discontinuation can guide clinicians in making evidence-based decisions when treating first-episode patients

    Schizophrenia and related disorders have heterogeneous outcomes. Individualized prediction of long-term outcomes may be helpful in improving treatment decisions. Utilizing extensive baseline data of 523 patients with a psychotic disorder and variable illness duration, we predicted symptomatic and global outcomes at 3-year and 6-year follow-ups. We classified outcomes as (1) symptomatic: in remission or not in remission, and (2) global outcome, using the Global Assessment of Functioning (GAF) scale, divided into good (GAF &gt;= 65) and poor (GAF &lt; 65). Aiming for a robust and interpretable prediction model, we employed a linear support vector machine and recursive feature elimination within a nested cross-validation design to obtain a lean set of predictors. Generalization to out-of-study samples was estimated using leave-one-site-out cross-validation. Prediction accuracies were above chance and ranged from 62.2% to 64.7% (symptomatic outcome), and 63.5-67.6% (global outcome). Leave-one-site-out cross-validation demonstrated the robustness of our models, with a minor drop in predictive accuracies of 2.3% on average. Important predictors included GAF scores, psychotic symptoms, quality of life, antipsychotics use, psychosocial needs, and depressive symptoms. These robust, albeit modestly accurate, long-term prognostic predictions based on lean predictor sets indicate the potential of machine learning models complementing clinical judgment and decision-making. Future model development may benefit from studies scoping patient's and clinicians' needs in prognostication.</p

    Comprehensive dissection of prevalence rates, sex differences, and blood level-dependencies of clozapine-associated adverse drug reactions

    Clozapine is often underused due to concerns about adverse drug reactions (ADRs) but studies into their prevalences are inconclusive. We therefore comprehensively examined prevalences of clozapineassociated ADRs in individuals with schizophrenia and demographic and clinical factors associated with their occurrence. Data from a multi-center study (n=698 participants) were collected. The mean number of ADRs during clozapine treatment was 4.8, with 2.4% of participants reporting no ADRs. The most common ADRs were hypersalivation (74.6%), weight gain (69.3%), and increased sleep necessity (65.9%), all of which were more common in younger participants. Participants with lower BMI prior to treatment were more likely to experience significant weight gain (>10%). Constipation occurred more frequently with higher clozapine blood levels and doses. There were no differences in ADR prevalence rates between participants receiving clozapine monotherapy and polytherapy. These findings emphasize the high prevalence of clozapine-associated ADRs and highlight several demographic and clinical factors contributing to their occurrence. By understanding these factors, clinicians can better anticipate and manage clozapine-associated ADRs, leading to improved treatment outcomes and patient well-being

    This case report examines the possible correlation between the clozapine/norclozapine ratio and the occurrence of constipation and paralytic ileus. We present the case of a 42-year-old patient diagnosed with schizoaffective disorder undergoing clozapine therapy. Despite intensive treatment with clozapine, haloperidol, valproic acid and biweekly electroconvulsive therapy sessions for over a year, florid psychotic symptoms and fluctuating mood swings persisted. Therefore, valproic acid was replaced by carbamazepine, a potent inducer of several CYP450-enzymes. To maintain clozapine plasma levels, fluvoxamine, a CYP1A2-inhibitor, was introduced at a dose of 25 mg before this switch. After addition of carbamazepine, there was a significant decline in clozapine levels, necessitating an increase in fluvoxamine dosage to 50 mg. Five weeks later the patient was admitted to a general hospital with a diagnosis of paralytic ileus. Treatment with enemas proved effective. Drug concentration analysis revealed a 2.5-fold increase in norclozapine levels in the weeks preceding hospital admission, resulting in an inverted clozapine/norclozapine ratio. Treatment with clozapine, carbamazepine and fluvoxamine was continued as the patient demonstrated clinical improvement on carbamazepine. Concurrently, an intensive laxative regimen was initiated. Two weeks later, the patient was readmitted to the general hospital due to suspected paralytic ileus and faecal vomiting, once again displaying an inverted clozapine/norclozapine ratio. We discuss potential mechanisms contributing to the occurrence of the paralytic ileus in this patient, including the antagonism of muscarinic M3 receptors by both clozapine and norclozapine, as well as the agonism of delta-opioid receptors by norclozapine. This case highlights the potential significance of both the clozapine/norclozapine ratio and absolute norclozapine levels as risk factors for constipation and paralytic ileus in patients on clozapine therapy.</p

    Objective: The aim of this study was to examine satisfaction with pharmacologic treatment in patients who received antipsychotic polypharmacy compared to antipsychotic monotherapy. Methods: This longitudinal cohort study was conducted in two mental health care institutes in Amsterdam, the Netherlands, among a randomly selected sample of in- and outpatients with a severe mental illness. Analyses were performed on data collected in 2011 for 185 patients who were diagnosed with schizophrenia or unspecified psychosis according to DSM-IV criteria. The outcome measure was the Treatment Satisfaction Questionnaire for Medication, version II. One-way analyses of covariance were performed to examine differences in treatment satisfaction between patients who received antipsychotic polypharmacy compared to antipsychotic monotherapy while controlling for the effects of clozapine, antipsychotic dose, and use of long-acting injectable antipsychotics. Results: Twenty percent of patients in this sample received 2 antipsychotic agents; in half of those patients, this involved a combination with clozapine. Polypharmacy resulted in less satisfaction with side effects compared to monotherapy (P= .002). No difference was found in perceived effectiveness (P= .168) or overall medication satisfaction (P= .379). Conclusions: These results confirm that antipsychotic polypharmacy is common in a random in- and outpatient sample. Patients who receive 2 antipsychotic agents are just as positive about the effectiveness and ease of use of and overall satisfaction with their medication compared to those who receive antipsychotic monotherapy. They are, however, less satisfied with perceived side effects of their medication, which may indicate that side effect profiles of antipsychotic combinations are less favorable

    “As a psychiatry resident I am invited to explore my identity. But when I accept that invitation, I still encounter a wall.” A qualitative study on inclusion experienced by psychiatry residents with a migration background, sexual minority identity and/or working-class background

    Diversity in terms of class, sexual identity and migration background among medical students in high income countries has increased greatly in recent decades. Some research into the experiences of these new groups of doctors has been performed. However, no previous research into the experiences of psychiatry residents specifically, is known. This qualitative study investigates how psychiatry residents, from these minoritized groups, experience their training regarding inclusion. Inclusion is defined as the degree to which one’s needs for connection and for being valued in one’s uniqueness, is satisfied. In-depth interviews with 16 psychiatry residents were conducted. These interviews were transcribed and coded using MaxQDA software. Initial themes that were constructed, were explored further in subsequent interviews and linked to literature. Finally, the developed themes were ordered in a model conceptualizing inclusion. Participants reported high belongingness within psychiatry training. Their experienced value in uniqueness, however, was generally quite low. Participants reported to experience little interest in and sensitivity for their perspectives and lived experiences from their co-workers. When faced with stigmatization and discrimination, participants reported lack of support from their colleagues. Assimilation was found to be the most frequently used coping strategy in dealing with diversity. Participants seemed to conform to the ‘neutral’ norm and experienced barriers in expressing themselves. Through this mechanism of assimilation, the added value that participants might bring with their unique knowledge and lived experiences was not used, both in patient care and in creating an inclusive climate within the organization. Moreover, assimilation is associated with psychological strain

    The impact of affective symptoms on personal recovery of patients with severe mental illness

    Background: Clinical recovery is often defined as remission of symptoms. Personal recovery is described as growing beyond the catastrophic effects of mental illness, sometimes despite ongoing symptoms. Aims: To examine the relationship between the severity of clinical symptom domains and personal recovery in patients with severe mental illness (SMI). Methods: Symptom severity and personal recovery of 105 outpatients with SMI at Mentrum, part of Arkin Institute for Mental Health in Amsterdam, the Netherlands, were assessed using the Brief Psychiatric Rating Scale–Expanded Version (BPRS-E) and the Mental Health Recovery Measure (MHRM). Correlation and regression analyses were used to investigate the associations. Results: The multiple regression analysis showed that only affective symptoms significantly predicted personal recovery, whereas neither positive nor negative symptom severity added to the explained variance in the model. Conclusion: The association between affective symptoms and personal recovery in patients with SMI implies that treatment of affective symptoms may advance personal recovery, and/or support of personal recovery may improve mood, whereas focussing on treatment of psychotic symptoms might not be the key to personal recovery. More research is needed to elucidate causal interrelations

    Patients’ and volunteer coaches’ experiences with an informal social network intervention in forensic psychiatric care: a qualitative analysis

    Abstract Background: Improving supportive social networks in forensic psychiatric patients is deemed important due to the protective effects of such networks on both mental health problems and criminal recidivism. Informal interventions targeted at social network enhancement by community volunteers showed positive effects in various patient and offender populations. However, these interventions have not specifically been studied in forensic psychiatric populations. Therefore, forensic psychiatric outpatients’ and volunteer coaches’ experiences with an informal social network intervention were explored in this study. Methods: This qualitative study was based on semi-structured interviews conducted alongside an RCT. Forensic outpatients allocated to the additive informal social network intervention, and volunteer coaches, were interviewed 12 months after baseline assessment. Interviews were audio-recorded and transcribed verbatim. Reflexive thematic analysis was used to identify and report patterns in the data. Results: We included 22 patients and 14 coaches in the study. The analysis of interviews revealed five main themes reflecting patients’ and coaches’ experiences: (1) dealing with patient receptivity, (2) developing social bonds, (3) receiving social support, (4) achieving meaningful change, and (5) using a personalized approach. Patient receptivity, including willingness, attitudes, and timing, was a common reported barrier affecting patients’ engagement in the intervention. Both patients’ and coaches’ experiences confirmed that the intervention can be meaningful in developing new social bonds between them, in which patients received social support. Despite, experiences of meaningful and sustainable changes in patients’ social situations were not clearly demonstrated. Coaches’ experiences revealed broadened worldviews and an enhanced sense of fulfillment and purpose. Finally, a personalized, relationship-oriented rather than goal-oriented approach was feasible and preferable. Conclusion: This qualitative study showed positive experiences of both forensic psychiatric outpatients and volunteer coaches with an informal social network intervention in addition to forensic psychiatric care. Notwithstanding the limitations, the study suggests that these additive interventions provide an opportunity for forensic outpatients to experience new positive social interactions with individuals in the community, which can initiate personal development. Barriers and facilitators to engagement are discussed to improve further development and implementation of the intervention.
