Motivations for and Experiences With Antipsychotic Tapering Among Patients With Schizophrenia Seeking Guided Dose Reduction

OBJECTIVE

Over time, most patients with schizophrenia wish to reduce or discontinue their antipsychotic medication treatment. In Denmark, a specialized government-funded outpatient clinic was established to offer guided antipsychotic dose reduction. This study aimed to provide data on motivations for and previous experiences with antipsychotic tapering among patients attending the clinic.

METHODS

Patients completed an open-ended survey on their motivations for discontinuing or tapering antipsychotic medication and recorded their expectations about these outcomes. They also provided information on previous experiences with discontinuing medication and their level of symptoms, functioning, and side effects.

RESULTS

The survey was completed by 76 (86%) of 88 patients. The main motivations for discontinuing antipsychotics were adverse effects (71%) and uncertainty about the necessity of taking antipsychotics (29%). Other factors included concerns about long-term effects, disagreeing with the diagnosis, experiencing an insufficient effect, and feeling stigmatized by taking medication. Previous experience with discontinuation of antipsychotics was reported by 42 patients, of whom 23 reported relapse as the outcome. Most patients believed they could succeed in dose reduction (N=73 of 75, 97%) or discontinuation (N=62 of 75, 83%).

CONCLUSIONS

Motivational factors reported for professionally guided antipsychotic dose reduction align with previous studies examining patients choosing to discontinue these medications. Despite reports of relapse during prior discontinuation attempts, most patients still reported motivation for and belief in successful dose reduction or discontinuation. An understanding of patients' motivations and beliefs is paramount to an optimal treatment alliance. Offering guided dose reduction may reduce sudden and unsupported discontinuation of antipsychotics.

Deprescribing antipsychotics in patients with schizophrenia: findings from a specialized clinic

BACKGROUND

While antipsychotic medication reduces the risk of relapse for patients with schizophrenia, high prevalence of adverse effects results in low adherence. Lower doses of antipsychotics have been associated with increased level of function but also with increased risk of relapse. This study presents findings from a specialized deprescribing clinic. In addition, we aim to identify clinical predictors for relapse.

METHODS

Patients diagnosed with schizophrenia were referred to the clinic, which offers a six-month guided tapering program. Antipsychotic dose was reduced by 10% every four weeks. Patients were monitored closely for symptom progression or decrease in level of function, with defined cut-offs prompting a pause in or cessation of dose reduction.

RESULTS

After 12 months, the antipsychotic dose was reduced from 404 (±320 mg) to 255 (±236 mg) chlorpromazine equivalent. Of the 88 patients included, 22 (27%) experienced relapse during the six-month tapering period, while 29 (37%) experienced relapse at the 12-month follow-up visit and nine patients were antipsychotic free. Patients who remained stable experienced a slightly increased level of functioning and markedly fewer side effects (p < 0.001). Following relapse, patients were clinically stabilized and showed an improved attitude toward antipsychotic medication. The predictive models were weak.

CONCLUSIONS

We show that most patients undergoing guided antipsychotic tapering remained stable after one year and improved in level of function, while most patients who relapsed were quickly stabilized. Our inability to create strong predictive models could be due to limitations in the study design, warranting future studies exploring tapering of antipsychotics in patients with schizophrenia.

Association of Antipsychotic Polypharmacy and Two-Year All-Cause Mortality: A Population-Based Cohort Study of 33,221 Italian Continuous Users

Background: Differences in survival between patients treated with antipsychotic monotherapy vs. polytherapy are debated. This study aimed to examine the association of antipsychotic polytherapy with 2-year all-cause mortality in a population-based cohort. Methods: Data were retrieved from healthcare databases of four local health units of Lombardy, Italy. Subjects aged 18-79 years who received continuous antipsychotic prescriptions in 2018 were identified. Overall survival among patients with antipsychotic monotherapy vs. polytherapy was compared. A multivariate Cox PH model was used to estimate the association between antipsychotic therapy, or antipsychotic use (continuous vs. non-continuous), and all-cause mortality. Adjustments were made for the presence of metabolic disturbances, total antipsychotic dosage amount (olanzapine equivalent doses), age, and sex. Results: A total of 49,875 subjects receiving at least one prescription of antipsychotics during 2018 were identified. Among the 33,221 patients receiving continuative antipsychotic prescriptions, 1958 (5.9%) experienced death from any cause at two years. Patients with continuous antipsychotic use had a 1.13-point increased mortality risk compared with non-continuous users. Patients treated with antipsychotic polytherapy showed an adjusted mortality risk increased by 17% (95% CI: 2%, 33%) compared to monotherapy. Conclusions: The study highlights the potential risks associated with antipsychotic polypharmacy, emphasizing the importance of optimizing drug prescriptions to improve patient safety and reduce mortality rates in individuals receiving antipsychotic therapy.

The Association of Antipsychotic Postponement With 5-Year Outcomes of Adolescent First-Episode Psychosis

Background and Hypothesis

Based on the need-adapted approach, delaying antipsychotics could help identify first-episode psychosis (FEP) adolescents who might not require them. However, some individuals might need antipsychotics, and postponing could harm their prognosis. This nationwide register-based follow-up aimed to test these two hypotheses.

Study Design

All adolescents aged 13-20 with a psychotic disorder (ICD-10 codes: F20-F29) in Finland between 2003 and 2013 were identified (n = 6354) from national registers. For each case, a fixed 1825-day follow-up period was established from the onset of psychosis or until death. The outcome was considered "good" if adolescents did not die and had not received psychiatric treatment and/or disability allowances during the final year of follow-up. Testing the first hypothesis involved all antipsychotic treatment-naïve adolescents with FEP (n = 3714). The second hypothesis was tested with a sub-sample of only those who had received antipsychotics during follow-up (n = 3258). To account for baseline confounders, hypotheses were tested via a stabilized inverse probability of treatment weighted generalized linear models with logit link function.

Study Results

Immediate antipsychotic treatment after the onset of psychosis was associated with poor 5-year outcome (adjusted odds ratio [aOR]: 1.8, 95% CI: 1.6-2.1). There was no statistically significant association between antipsychotic postponement and treatment outcome in those who eventually received antipsychotic treatment (aOR: 1.02, 95% CI: 0.7-1.2, P: .8), thus not providing support for second hypothesis.

Conclusions

There is a significant subgroup of adolescent with psychosis who do not require immediate antipsychotic treatment. A more robust design is needed to evaluate the causality of the observed association.

Comparative risks of all-cause mortality for Veterans with schizophrenia with ongoing receipt of clozapine and other antipsychotic medications

To guide care for patients with schizophrenia, the Veterans Health Administration (VHA) evaluated the associations between current or recent use of clozapine and all-cause mortality and explored associations for other antipsychotic medications. Using a case-control design, patients with schizophrenia who died in fiscal years 2014-2018 were matched on age, sex, race, and VHA facility to up to 10 controls who were alive on the case's date of death (index date). Medication coverage during the 91 days before the index date was classified as none, partial (1-44 days), and consistent (45-91 days). Medication coverage patterns during the index period were compared to coverage patterns during the period of 92-182 days prior to index date with each medication coverage classified as no change, no coverage, increased, or decreased. Conditional logistic regression analyses controlling for patient characteristics identified no associations of consistent or increasing clozapine coverage with mortality; partial and decreasing coverage were associated with greater mortality and these effects did not differ from those of other the medications considered. Exploratory analyses considering non-clozapine antipsychotic agents suggest that consistent coverage by olanzapine may be associated with increased mortality, that mortality associated with olanzapine may be greater than aripiprazole, and that this effect can be attributed primarily to patients with diabetes. Further study of this topic is needed.

What should be the future focus of mental health nursing? Exploring the perspectives of mental health nurses, consumers, and allied health staff

The landscape of mental health care and service delivery is changing, as is our understanding of the underlying causes for mental distress. It is now apparent that biogenic explanations have been overstated and instead experiences of trauma and adversity constitute the main contributor to people's experiences of mental health challenges. The shortcomings of treatments traditionally used in mental health care are also evident, and with a contemporary focus on person-centred care, the utility of diagnostic labels has been called into question. Taking all this into consideration, this study sought to explore, what should be the future focus of mental health nursing? Three separate focus groups were conducted. One with a sample of senior clinical mental health nurses, one with a sample of consumer representatives and another with allied health professionals. The common theme across all three focus groups was the centrality of the therapeutic role of mental health nurses (MHNs). Consumers and allied health participants, in particular, advocated for a de-emphasis on medications, psychiatric diagnoses, and custodial practices. The MHNs role in health promotion, working collaboratively with consumers, being hopeful, understanding the individual perspective, and appreciating the social determinants of mental health were all highlighted in framing the future focus of MHN practice.
