Are depot antipsychotics more coercive than tablets? The patient's perspective

Developing STEP-SE: A Qualitative Usability Study of a Novel Patient-Reported Outcomes Tool for Managing Side Effects in Shared Decision-Making for Schizophrenia Spectrum Disorder Care

BACKGROUND

Schizophrenia treatment with antipsychotics often results in side effects that impact adherence and quality of life. Managing these effects remains challenging, as it requires balancing efficacy and tolerability. The Schizophrenia Technological Evaluation of Patient Side Effects (STEP-SE) app aims to aid side effects monitoring and management through shared decision-making (SDM).

AIM

This study aimed to evaluate the usability of the STEP-SE app for patients and clinicians in managing antipsychotic side effects.

METHODS

Sixteen stable outpatients and 14 psychiatrists participated in semi-structured interviews after using the STEP-SE app. Questions explored ease of use, information clarity, user needs fulfilment, patient-clinician collaboration, treatment adherence improvement, patient empowerment and clinical utility. Data were analysed thematically.

RESULTS

Overall satisfaction with STEP-SE was high. Both groups found that the tool improved patient involvement, provided reliable information to enhance therapeutic alliance, posed low risks of misunderstanding and had an intuitive interface. Patients felt more motivated and empowered. Clinicians appreciated guideline consistency. Preferences differed regarding data visualization formats.

DISCUSSION

STEP-SE shows potential for aiding SDM on antipsychotic side effects. Patients gained motivation, and clinicians felt reassured. Refinements around mobile access, graphics and features could augment utility. Generalizability is limited given the stable patient sample.

CONCLUSION

Preliminary findings suggest that STEP-SE effectively engages patients, empowers them and supports clinicians in collaborative side effect management. Further testing with diverse user groups is warranted.

PATIENT OR PUBLIC CONTRIBUTION

The current study was designed to gather patient and public feedback for the development of our decision aid tool, STEP-SE. Participants interacted with the tool's prototype in interactive sessions, providing insights and identifying technical issues. Their feedback was crucial for enhancing the tool, with each suggestion and bug report carefully considered for future iterations. The participants' contributions were key in optimizing STEP-SE's features and ensuring its relevance and reliability. We thank all who shared their time and perspectives, significantly shaping the tool's user-centred design.

Aripiprazole IM depot as an option for the treatment of bipolar disorder

Introduction: Long-acting injectable (LAI) antipsychotic drugs are developed to reduce daily intake need and to overcome treatment non-adherence. Aripiprazole IM depot refers to two long-acting aripiprazole formulations, once monthly monohydrate (AOM) and aripiprazole lauroxil. AOM has been approved for schizophrenia since 2012 and for bipolar disorder since 2017. Aripiprazole lauroxil is approved for schizophrenia, not for bipolar disorder.Areas covered: To assess the effect of AOM in bipolar disorder, the authors searched PubMed and ClinicalTrials.gov for randomized trials using AOM in patients with bipolar disorder. Included were four studies covering efficacy, functioning, quality of life, and safety/tolerability. Studies lasted 12 months.Expert opinion: AOM reduced symptoms of patients with bipolar disorder and a manic episode, increased functioning and quality of life, and protected from recurrence of manic episodes. It proved to be safe/tolerable, with only akathisia occurring in ≥10% of cases and more frequently than with placebo. However, there were only 143 patients receiving AOM in the considered studies. Included studies were backed in their conclusions by other literature, but they come from 2017-2018. No studies are expected or planned in the near future. Aripiprazole lauroxil has not applied for approval in bipolar disorder and there is no sign it will.

Patient subjective experience of treatment with long-acting injectable antipsychotics: a systematic review of qualitative studies

ABSTRACT Objective: To gain a better understanding of how long-acting injectable antipsychotic (LAI) therapy is perceived by patients. Methods: A search for qualitative studies has been carried out on PubMed, Google Scholar, PsycINFO and PsycArticles, yielding 11 studies suitable for a review of qualitative studies. The reporting approach chosen was meta-ethnography, following the ENTREQ statement recommendations. Key concepts common to the different studies were extrapolated and then analysed in a systematic and comparative way. Results: Some recurrent issues were associated with LAIs, such as fear of coercion, fear of needles and lack of knowledge about depot therapy. These topics are linked to each other and the patients most concerned about the disadvantages of LAIs are those who are less informed about them, or who have experienced coercion and trauma during hospitalisation. On the other hand, patients who had already received LAIs, and those who had a good therapeutic relationship with their healthcare providers expressed satisfaction with this form of treatment and its continuation. Conclusion: Long-acting injectable antipsychotics are a tool in the management of mental disorders, and a viable alternative to oral medication. Patients show curiosity towards this method of administration, but lack of knowledge is a common finding. Shared decision making about the use of LAIs antipsychotics requires that patients receive accurate information and support for their decision regarding medication.

Risk of withdrawal of consent for treatment with long-acting injectable versus oral antipsychotics: A meta-analysis of randomized controlled trials

BACKGROUND

Despite the clinical importance of antipsychotic long-acting injections (LAIs) in the treatment of schizophrenia, their use may be limited by patients' reluctance to accept the injections. No studies to date have investigated whether patients are more likely to withdraw their consent to treatment with LAIs than to treatment with oral antipsychotics (OAPs). Therefore, we performed a meta-analysis of randomized controlled trials (RCTs) to compare the risk of withdrawal of consent between the 2 routes of administration.

METHODS

PubMed, the Cochrane Library, PsycINFO, and CINAHL were systematically searched. RCTs with open-label or rater-masked design that compared LAIs with OAPs were selected. Data on study discontinuation due to withdrawal of consent and/or loss to follow-up were extracted.

RESULTS

A total of 16 studies (4815 patients) that met the study eligibility criteria were included in the meta-analysis. There was no significant difference between the LAI and OAP groups in the risk of cessation of treatment because of withdrawal of consent. Similarly, there was no significant difference in the risk of study discontinuation because of withdrawal of consent plus loss to follow-up.

CONCLUSIONS

These findings were unexpected and suggest that patients may not be more hesitant to continue LAIs than OAPs after consenting to or receiving treatment. Nevertheless, patients should be provided detailed explanations about the use of LAIs and a support system that encourages them to continue treatment.

Persistent Barriers to the Use of Long-Acting Injectable Antipsychotics for the Treatment of Schizophrenia

PURPOSE/BACKGROUND

One of the major challenges in the treatment of schizophrenia is nonadherence, defined as the failure to take medications as prescribed. Nonadherence is a strong predictor of symptom relapse, hospital readmission, and poorer long-term outcome. Although long-acting injectable antipsychotics (LAIs) have been found to be superior to their oral analogs at reducing relapse in large-scale meta-analyses, their prevalence seldom exceeds 30% even in populations with a history of nonadherence. We review multiple barriers to the use of LAI utilization and suggest strategies to address them.

METHODS/PROCEDURES

We searched for the following terms: long-acting injectable/depot antipsychotics, schizophrenia, barriers, and attitude/perception in both the PubMed search index and Google scholar from 1995 to 2018. A total of 329 studies were selected, of which data from 13 were reviewed for this article. Only peer-reviewed studies, randomized controlled trials, systematic reviews, and meta-analyses that describe barriers to using LAIs were included.

FINDINGS/RESULTS

Several barriers to using LAIs were identified. These are organized into 3 overarching categories: those related to the clinician; those related to the patient; and systems barriers. Clinician factors include the perception of LAIs as coercive, fears of not being able to control the dose, as well as current practice patterns and guidelines. Patient factors include perception of the injection as painful or intrusive, general lack of knowledge, and a sense of coerciveness. For each identified barrier, we propose potential solutions.

IMPLICATIONS/CONCLUSIONS

We identified multiple barriers to using LAIs in patients with schizophrenia. Specific strategies are suggested for overcoming each of these barriers.

Patterns of long acting injectable antipsychotic use and associated clinical factors in schizophrenia among 15 Asian countries and region

INTRODUCTION

Patterns of clinical use of long-acting injectable (LAI) antipsychotic drugs in many countries, especially in Asia, for treatment of patients diagnosed with chronic psychotic disorders including schizophrenia are not well established.

METHODS

Within an extensive research consortium, we evaluated prescription rates for first- (FGA) and second-generation antipsychotic (SGA) LAI drugs and their clinical correlates among 3557 subjects diagnosed with schizophrenia across 15 Asian countries and region.

RESULTS

Overall, an average of 17.9% (638/3557; range: 0.0%-44.9%) of treated subjects were prescribed LAI antipsychotics. Those given LAI vs orally administered agents were significantly older, had multiple hospitalizations, received multiple antipsychotics more often, at 32.4% higher doses, were more likely to manifest disorganized behavior or aggression, had somewhat superior psychosocial functioning and less negative symptoms, but were more likely to be hospitalized, with higher BMI, and more tremor. Being prescribed an FGA vs SGA LAI agent was associated with male sex, aggression, disorganization, hospitalization, multiple antipsychotics, higher doses, with similar risks of adverse neurological or metabolic effects. Rates of use of LAI antipsychotic drugs to treat patients diagnosed with schizophrenia varied by more than 40-fold among Asian countries and given to an average of 17.9% of treated schizophrenia patients. We identified the differences in the clinical profiles and treatment characteristics of patients who were receiving FGA-LAI and SGA-LAI medications.

DISCUSSION

These findings behoove clinicians to be mindful when evaluating patients' need to be on LAI antipsychotics amidst multifaceted considerations, especially downstream adverse events such as metabolic and extrapyramidal side effects.

Perceptions of Psychiatrists Toward the Use of Long-Acting Injectable Antipsychotics: An Online Survey Study From India

PURPOSE/BACKGROUND

Despite proven benefits of long-acting injectables (LAIs), these are frequently underused by the psychiatrists. Accordingly, this study aimed to explore the perceptions of psychiatrists toward the use of LAI antipsychotics in their routine clinical practice.

METHODS/PROCEDURE

An online e-mail survey was conducted by using Survey Monkey platform.

RESULTS

A total of 622 psychiatrists with a mean age of 41 years who were in psychiatric practice for approximately 14 years participated in the survey. Participants reported using LAI, mainly for patients with schizophrenia, with LAI prescribed to approximately one-tenth (9.30%) of their patients in acute phase of illness and in one-fifth (18.42%) of patients in stabilization/stable phase. Fluphenazine decanoate (32.7%) was the most commonly used LAI followed by flupenthixol decanoate (19.5%), haloperidol decanoate (17.8%), and olanzapine pamoate (11.1%). The most common reasons for starting LAI were history of medication (100%) and treatment (80.5%) nonadherence, followed by having frequent relapses/exacerbations of symptoms (54.8%). Overall, more than half of the participants felt the level of acceptance of LAI among patients offered to be quite reasonable (54.3%), and mostly, LAIs were used as combination therapy with oral antipsychotics (73.6%). Despite all these, approximately three-fifths (59%) of the participants reported that they underuse LAI to a certain extent, with most common reasons that deter them from using LAI being the cost (55.45%), lack of interest of patients in receiving LAI (42.9%), lack of regular availability (41.3%), and patients being scared of receiving injectables (41.2%).

CONCLUSIONS/IMPLICATIONS

The LAI antipsychotics despite having several benefits are still underused by a substantial proportion of practicing psychiatrists.

"I live, I don't work, but I live a very normal life"-A qualitative interview study of Scandinavian user experiences of schizophrenia, antipsychotic medication, and personal recovery processes

PURPOSE

To illuminate user experiences of schizophrenia, reasons for receiving antipsychotic medication, and encounters with mental health services.

DESIGN AND METHODS

24 semistructured qualitative research interviews with schizophrenia patients treated with 3-monthly paliperidone palmitate across Scandinavia were synthesized in qualitative content analysis.

FINDINGS

Participants describe considerable challenges in everyday functioning. Simultaneously, they rate their current mental and physical well-being high and seem satisfied with their lives. These pathways indicate personal recovery.

PRACTICE IMPLICATIONS

The participants emphasize the importance of trustful relations with healthcare professionals, therapeutic conversations, antipsychotic medication in a 3-monthly formulation, and support from relatives.

Hospitalization Rates and Therapy Costs of German Schizophrenia Patients Who are Initiated on Long-Acting Injectable Medication: A Mirror-Image Study

BACKGROUND

Long-acting injectable (LAI) antipsychotics can reduce relapse, hospitalization, and costs in patients with schizophrenia. However, real-world evidence assessing the impact of treatment with LAIs in Germany is limited.

OBJECTIVE

To provide updated evidence on the impact of LAI initiation on hospitalization rates and therapy costs.

METHODS

Using a mirror-image design, claims data of 850 German patients with schizophrenia who initiated treatment with LAIs during 2013-2015 was retrospectively analyzed. For the included patients, costs and resource utilization were compared for the 12 months before the index date (first initiation of LAI) and the 12 months after the index date. Annual treatment costs, hospitalization rates, ambulatory visits, sick leaves and medical aids were assessed. Two models were used to evaluate hospitalization and its costs. In model 1, hospitalization during the index date (first LAI prescription in 2013-2015) was allocated to the "pre-" time interval, while in model 2 it was neither attributed to the pre- nor to the post-index date. Regression analysis was performed to identify patients who benefited the most in terms of cost reduction from LAI initiation.

RESULTS

Medication costs were significantly higher post-switching to LAI compared with pre-switching period (€3832 vs €799; p < 0.001). In model 1, number of hospitalizations, days hospitalized, and associated costs were significantly lower post-switching compared with pre-switching (2.3 vs 2.6; 59.2 vs 73.4; and €5355 vs €11,908, respectively; all p < 0.001). Similar results were obtained for costs in model 2 (€5355 vs €10,276; p < 0.001). Mean total costs reduced significantly from pre-switching to post-switching period in model 1 (€13,776 vs €10,418; p < 0.001). Patients with characteristics such as higher number of non-psychiatric and psychiatric inpatient stays during the pre-index period (all p < 0.05) benefited the most from cost reduction after LAI initiation.

CONCLUSION

In this cohort of German patients with schizophrenia, treatment initiation with LAI resulted in reduced hospitalization rates and total costs.

Pill or needle? Determinants of the preference for long-acting injection over oral treatment in people facing chronic illness

Although long-acting injection (LAI) is presented as first line treatment option for patients with psychosis, negative attitudes toward this galenic negatively impact the selection of this treatment option. However, these negative attitudes may not be confined to patients but also observed in the general population. A web-based study on 1807 participants was conducted during which participants imagined that they had a particular chronic illness based on clinical vignettes (mental illnesses: schizophrenia, depression; somatic illnesses: multiple sclerosis, rheumatoid arthritis). The frequency of relapse and the intensity of symptoms were experimentally manipulated in the vignettes. Participants rated their subjective distress associated with each vignette, their belief in the effectiveness of treatment, and their treatment preference regarding medication. We examined under which conditions LAI was preferred over pills. Statistical analyses were performed using Bayesian methods. Results showed that participants preferred LAI over pills in 40.5% to 50.8% of cases. LAI was more preferred for illnesses with low frequency of relapse, low subjective distress, and for somatic than for mental illnesses. The perceived advantage for LAI over pills and the belief about the better efficiency of LAI were the main factors that drove the preference for LAI. Keeping in mind some advantages of LAI, the public negative representations of injections might partially influence patients' prejudices against LAI. These attitudes should be named and discussed with the patients when LAI seems to represent a relevant therapeutic option.

Long-acting injectable antipsychotics: Six-month follow-up of new outpatient treatments in Bologna Community Mental Health Centres

Purpose

This study aims to describe factors associated to treatment continuity and psychiatric relapses in patients treated with Long Acting Injectable antipsychotics (LAIs) in Bologna Community Mental Health Centers (CMHCs).

Methods

New LAI treatments administered between July 1, 2010 and June 30, 2015 in CMHCs were selected. The cohort was followed-up for 6 months; predictors of continuity and psychiatric admissions were investigated by using logistic regression- and Cox- analysis respectively.

Results

Among the cohort of 1 070 patients, only 222 (21%) continued LAI treatment during the follow-up. LAI continuity was higher with first generation agents (OR: 1.71, 95%CI 1.18–2.49) and in case of previous psychiatric hospitalizations (OR 2.00, 95%CI 1.47–2.74). Incidence of psychiatric hospital admissions showed a sharp reduction in the follow-up compared with 6-month period before initiation (from 458 to 212), and was associated with previous psychiatric hospitalizations (HR 3.20, 95%CI 2.22–4.59), immigration (HR 3.13, 95%CI 1.28–7.69) and LAI discontinuation (HR 1.14, 95%Cl 1.01–1.97).

Conclusions

Psychiatric hospital admission before LAI initiation was the main predictor both of LAI continuity and hospitalization during the follow-up.

Attitudes toward long-acting injectable antipsychotics among patients with schizophrenia in Japan

BACKGROUND

Long-acting injectable antipsychotics (LAIs) are regarded as an important alternative to oral medication for patients with schizophrenia. However, LAIs remain under-utilized in clinical practice.

AIMS

The aims of this investigation were to 1) obtain information on patients' attitudes toward LAIs and 2) assess factors associated with patients' acceptance of LAIs, and 3) identify predictors of the discrepancy between patients and referring psychiatrists' opinions regarding the appropriateness for LAIs.

METHODS

Anonymized data were collected from a questionnaire distributed to 159 patients with schizophrenia and their referring psychiatrists at three psychiatric hospitals between February 2014 and July 2014. The patients completed an original questionnaire developed to evaluate their attitudes regarding LAIs. Regarding the appropriateness of LAI prescription, patients and their referring psychiatrists were asked to rate, on a 5-point scale, how appropriate they felt the depot prescription was for the patients. The participants also answered instruments to assess symptom severity, antipsychotic-induced extrapyramidal symptoms, functions, quality of life, and self-esteem levels.

RESULTS

Patients currently on LAIs have favorable attitudes toward LAIs with respect to side effects, relapse prevention, efficacy, pain, and cost. Expectation of relapse prevention was significantly associated with patients' acceptance of LAIs (answering that those drugs are appropriate for their own treatment). In addition, the discrepancy between the patients' and referring psychiatrists' opinions regarding the appropriateness of LAI treatment was significantly associated with symptom severity, expectation of relapse prevention, belief that LAIs are painful, and belief that LAIs offer a reduced range of antipsychotic choices.

CONCLUSION

Attitudes toward LAIs need to be considered when deciding whether to prescribe this formulation. Access to information on LAIs, including their benefit in relapse prevention, might enhance the acceptance and use of this formulation among patients with schizophrenia.

Positive views on antipsychotic long-acting injections: results of a survey of community patients prescribed antipsychotics

BACKGROUND

We aimed to assess patients' views about antipsychotic long-acting injections (LAIs).

METHODS

We interviewed patients prescribed an antipsychotic (oral or LAI) in our community teams. In a subanalysis, responses were analysed for differences between patients currently receiving an LAI and those prescribed only oral medication.

RESULTS

In total, 226 patients (57%) completed the study questionnaire. The majority agreed that LAIs ensured delivery of the right amount of medication and protection against hospital admissions (57% and 60%, respectively). A minority of participants were more concerned than not about the use of a needle (46%), pain from injection (48%) and the need to travel to receive the injection (34%). A majority expressed a preference for injection site (deltoid or gluteal) (65%) and clinic location (69%). A higher proportion of patients currently receiving an LAI compared with those prescribed oral medication thought an LAI was beneficial because this formulation obviated the need to: swallow tablets (63% versus 41%; p = 0.0013), remember to take tablets daily (75% versus 51%; p = 0.0004), remember tablets when away from home (72% versus 49%; p = 0008). Current LAI users were more likely than those on oral treatment to agree that LAIs keep patients out of hospital (76% versus 44%; p = 0.0001) and that the injection ensured delivery of the right amount of medication (71% versus 44%; p = 0.0002). Women were more likely than men to prefer administration by a clinician of the same gender (34% versus 12%; p = 0.0001).

CONCLUSIONS

In our study, a greater proportion of patients prescribed an LAI regarded LAIs as beneficial compared with those on oral medication.

Patients' experiences of long-acting injectable antipsychotics: a qualitative study

BACKGROUND

In this study, we applied a qualitative approach to explore patients' subjective experiences of long-acting injectable antipsychotics (LAIs).

METHODS

Patients undergoing psychiatric treatment from the chronic ward or outpatient department of a medical center in northern Taiwan who had experience with LAI treatment were enrolled. Information was obtained through semi-structured in-depth interviews. The interviews were audio-recorded and then translated verbatim, and the data were collected and analyzed concurrently to develop major themes and categories.

RESULT

In total, 14 participants (8 female) were interviewed. In a bio-psycho-social model, the participants used LAIs as a method to become "normal," in order to achieve a balance between the "effects" and "side effects" that may influence their daily lives. Their past experiences constructed their concepts about and expectations regarding LAIs, and their relationships with their family members and co-workers also modeled their experiences.

CONCLUSION

In our study, we sought to understand the experience of LAI in the daily life context of the patients. We attempted to use a bio-psycho-social model to evaluate the subjective experience of the patients; an improved understanding can help mental health specialists gain a closer insight into patient experience.

Conference proceedings of the 4th Masterclass Psychiatry: Transcultural Psychiatry - Diagnostics and Treatment, Luleå, Sweden, 22-23 February 2018 (Region Norrbotten in collaboration with the Maudsley Hospital and Tavistock Clinic London)

BACKGROUND

According to estimates from the European Commission, Europe has experienced the greatest mass movement of people since the Second World War. More than one million refugees and migrants have arrived in the European Union in the past few years. Mental health and primary care professionals are more likely than ever to meet patients from different cultures and backgrounds.

AIMS

To equip mental health and primary care professionals with transcultural skills to deal with patients from unfamiliar backgrounds.

METHOD

Lectures and case discussions to explore the latest advances in the diagnosis and treatment of serious mental health problems in a transcultural context.

RESULTS

Lectures covered transcultural aspects of mental health problems, treatment in different cultural and ethnic contexts, and assessment of risk factors for self-harm and harm in migrant populations.

CONCLUSIONS

Clinicians require a sound grounding in transcultural skills to confidently and empathically deal with patients from unfamiliar backgrounds.

Reducing the stigma of long acting injectable antipsychotics - current concepts and future developments

BACKGROUND

Long acting injectable antipsychotics (LAI-APs) are considered a major advance in psychiatric treatment concerning treatment adherence and outcomes. Yet, both, doctors and patients remain sceptical.

AIM

To explain the rationale for using LAI-APs, review their effectiveness and explore barriers to use.

METHOD

Clinical overview of LAI-APs from the patient and doctor's perspective.

RESULTS

LAI-APs were developed to increase adherence to treatment, thereby improving treatment outcomes. LAI-APs may reduce the risk of relapse and hospitalisation. Yet, the evidence from the few meta-analyses available remains weak. Both patients and doctors may associate LAI-APs with stigma and coercion. Current means of improving adherence include more focus on the therapeutic relationship, better information, adverse effects minimisation and half-life extension of LAI-APs. Future means of improving adherence include novel administration techniques that abolish the need for injection.

CONCLUSIONS

For both, clinicians and drug developers, drug adherence remains a major target for improving treatment outcomes.

Future development of a depot antiepileptic drug: What are the ethical implications?

Depot medications have been used for long-term treatment of many different medical conditions (schizophrenia, opioid addiction) and for prevention of pregnancy (birth control). In addition, proposals for depot medication for antidepressants have been made as a possible treatment for chronic depression. For the treatment of chronic epilepsy, there are currently no depot antiepileptic drugs (AEDs). However, there may be a role for them. Depot AEDs could improve medication adherence rates, thereby reducing the morbidity and mortality that are associated with ongoing seizures. This could help to reduce hospital costs for people with epilepsy. Potential patient populations that could benefit from a depot AED include patients with forgetfulness, socioeconomic barriers to access of daily oral medications, impaired gastric absorption or dysphagia, comorbid epilepsy and psychiatric disease, and personal preference to avoid the inconvenience of taking a medication daily or even multiple times per day. In this article, we review reasons to create a depot AED and the outcomes of doing so in the context of the pillars of bioethics: beneficence (to act in a patient's best interest), autonomy (to respect a patient as an individual and honor their preferences), nonmaleficence (to do no harm), and justice (to treat all persons fairly and equally).

Ethnic minority inequalities in access to treatments for schizophrenia and schizoaffective disorders: findings from a nationally representative cross-sectional study

BACKGROUND

Ethnic minority service users with schizophrenia and schizoaffective disorders may experience inequalities in care. There have been no recent studies assessing access to evidence-based treatments for psychosis amongst the main ethnic minority groups in the UK.

METHODS

Data from nationally representative surveys from England and Wales, for 10,512 people with a clinical diagnosis of schizophrenia or schizoaffective disorders, were used for analyses. Multi-level multivariable logistic regression analyses were used to assess ethnic minority inequalities in access to pharmacological treatments, psychological interventions, shared decision making and care planning, taking into account a range of potential confounders.

RESULTS

Compared with white service users, black service users were more likely prescribed depot/injectable antipsychotics (odds ratio 1.56 (95% confidence interval 1.33-1.84)). Black service users with treatment resistance were less likely to be prescribed clozapine (odds ratio 0.56 (95% confidence interval 0.39-0.79)). All ethnic minority service users, except those of mixed ethnicity, were less likely to be offered cognitive behavioural therapy, compared to white service users. Black service users were less likely to have been offered family therapy, and Asian service users were less likely to have received copies of care plans (odds ratio 0.50 (95% confidence interval 0.33-0.76)), compared to white service users. There were no clinician-reported differences in shared decision making across each of the ethnic minority groups.

CONCLUSION

Relative to white service users, ethnic minority service users with psychosis were generally less likely to be offered a range of evidence-based treatments for psychosis, which included pharmacological and psychological interventions as well as involvement in care planning.

Antipsychotic treatment of psychotic disorders in forensic psychiatry: Patients' perception of coercion and its predictors

BACKGROUND

Despite the major encroachment of coercive measures on the fundamental rights of affected forensic psychiatric patients, there is relatively few research done in this field. Considering the relevance of this subject for psychiatric care and the recent changes of the legal basis of coercive treatment in Germany, more studies are needed. The present study examines forensic psychiatric inpatients' perception of coercion regarding the prescribed antipsychotic medication and factors associated with the perception of coercion.

MATERIAL AND METHODS

Patients with schizophrenia, schizotypal and delusional disorders in two forensic psychiatric institutions in Southern Germany were interviewed about their experience of coercion related to antipsychotic medication. Due to a lack of appropriate psychometric scales, the perception of coercion regarding antipsychotic medication was assessed using an adapted version of the MacArthur Admission Experience Survey (aAES). The influence of sociodemographic and illness-related factors, of the attitude towards medication, insight into illness and symptom severity on the extent to which patients felt coerced to take the prescribed medication was analyzed. Two Visual Analog Scales, the Drug Attitude Inventory DAI-10, the Positive and Negative Syndrome Scale PANSS, the Fragebogen zur Krankheitseinsicht (Questionnaire about insight into illness) FKE-10 and the Coercion Experience Scale CES were used as psychometric scales.

RESULTS

50% of all patients eligible for the study gave their written consent. 70% of all participants had experienced coercive measures between admission and time of data assessment. The DAI-10 and the aAES correlated moderately, a high level of insight into illness being correlated to less perceived coercion. The FKE-10 and the aAES correlated moderately as well, a high level of insight into illness being correlated to less perceived coercion. The severity of symptoms (PANSS score) and the level of perceived coercion (aAES score) correlated weakly, participants with more severe symptoms perceived more coercion than those with less marked symptoms. A linear regression model showed that to what extent patients felt coerced to take the prescribed antipsychotic medication was mainly influenced by their attitude towards medication and the degree of insight into illness, to a lesser extent by symptom severity (R² = 0.565, p < 0.001). Sociodemographic factors were not related to the extent to which patients felt coerced to take the antipsychotic medication.

CONCLUSIONS

Predictors of the experience of coercion related to the prescribed antipsychotic medication of forensic psychiatric inpatients with schizophrenia and related disorders are not so much sociodemographic or illness-related factors as education or past medical history, but rather potentially influenceable variables such as insight into illness or attitude towards medication.

Oral Medication for Agitation of Psychiatric Origin: A Scoping Review of Randomized Controlled Trials

BACKGROUND

Understanding more about the efficacy and safety of oral second-generation antipsychotic medications in reducing the symptoms of acute agitation could improve the treatment of psychiatric emergencies.

OBJECTIVE

The objective of this scoping review was to examine the evidence base underlying expert consensus panel recommendations for the use of oral second-generation antipsychotics to treat acute agitation in mentally ill patients.

METHODS

The Cochrane Schizophrenia Group's Study-Based Register was searched for randomized controlled trials comparing oral second-generation antipsychotics, benzodiazepines, or first-generation antipsychotics with or without adjunctive benzodiazepines, irrespective of route of administration of the drug being compared. Six articles were included in the final review.

RESULTS

Two oral second-generation antipsychotic medications were studied across the six included trials. While the studies had relatively small sample sizes, oral second-generation antipsychotics were similarly effective to intramuscular first-generation antipsychotics in treating symptoms of acute agitation and had similar side-effect profiles.

CONCLUSIONS

This scoping review identified six randomized trials investigating the use of oral second-generation antipsychotic medications in the reduction of acute agitation among patients experiencing psychiatric emergencies. Further research will be necessary to make clinical recommendations due to the overall dearth of randomized trials, as well as the small sample sizes of the included studies.

[Aripiprazole long-acting for the maintenance treatment of schizophrenia.]

Antipsychotics are the cornerstone for the maintenance treatment of schizophrenia patients. Their long-acting formulations are helpful for preventing relapses through improvement of adherence to medication and a better pharmacokinetic coverage. However, their use is often reserved for refractory or non-observant clinical forms because of limitations among both clinicians and patients. The development of a new formulation of long-acting injectable aripiprazole administered every 4 weeks is a new option. Two randomized controlled trials vs. placebo and vs. oral aripiprazole respectively show a superiority and non-inferiority in terms of relapse prevention. Meanwhile, a mirror-image study demonstrates fewer hospitalizations. The safety profile is comparable to the oral formulation, particularly in terms of metabolic and neurological side-effects. As mentioned in various professional recommendations, long-acting injectable antipsychotics, so long-acting injectable aripiprazole, are one of the major strategies of the maintenance treatment for patients with schizophrenia.

A qualitative study of the attitudes of patients in an early intervention service towards antipsychotic long-acting injections

OBJECTIVES

The objective of this study was to investigate attitudinal themes to antipsychotic long-acting injections (LAIs) in patients in an early intervention team (EIT).

METHODS

Interviews were carried out with outpatients purposively sampled from an EIT to represent patients currently prescribed antipsychotic LAIs, oral antipsychotics and those not prescribed antipsychotic medication. Interviews were conducted and analysed according to grounded theory. Recruitment stopped when saturation of themes was reached.

RESULTS

Interviews from 11 patients were analysed (median age 24 years). Attitudes to LAIs were condensed into three key categories: therapeutic alliance and the psychiatrists' recommendation of antipsychotic medication; patients' knowledge and beliefs about LAIs; and patients' views regarding the appropriateness of LAIs. Participants valued their psychiatrist's recommendation as to the most appropriate antipsychotic. Attitudes to LAIs varied but were most positive among those currently receiving a LAI. Among those not prescribed LAIs, some were open to considering a LAI if their clinician recommended it but others were opposed to such treatment and preferred tables. There was a lack of awareness of LAIs as a treatment option among those not prescribed a LAI. Delay in being offered a LAI was reported in the group currently prescribed a LAI. Several participants associated oral antipsychotics, LAIs and mental illness with stigma. Some not prescribed a LAI had misperceptions about the nature of this treatment. Participants regarded the advantages of LAIs as convenience and avoiding forgetting to take tablets, while disadvantages included injection pain, fear of needles and coercion.

CONCLUSION

Lack of knowledge, misperceptions and stigma related to LAIs and other treatment options should be addressed by providing patients with accurate information. This will facilitate patients being involved in choices about treatment, and should they decide to accept medication, which drug and formulation is most appropriate for their needs. Clinicians should avoid making assumptions about patients' attitudes to LAIs; attitudes vary but some early intervention patients not prescribed LAIs are open to considering this treatment. Antipsychotic prescribing should result from a shared decision-making process in which clinicians and patients openly discuss the pros and cons of different formulations and drugs. The themes identified in this qualitative study require further exploration using quantitative methodology.

Cost effectiveness of paliperidone palmitate for the treatment of schizophrenia in Germany

BACKGROUND

Treatment with antipsychotic medication is an important element of relapse prevention in the management of schizophrenia, and can reduce inpatient stays. Recently, the long-acting atypical antipsychotic paliperidone long-acting injectable (PLAI), a once-monthly LAI antipsychotic, was approved for treatment of schizophrenia in Germany.

OBJECTIVE

To estimate, based on a previously published model, the cost effectiveness of PLAI compared with other common antipsychotic treatment strategies in patients diagnosed with schizophrenia in Germany.

METHODS

A Markov decision analytic model was adapted to the German healthcare system. The model considers the cost effectiveness for PLAI as a maintenance treatment for patients with schizophrenia from the payer perspective. The patients transition between eight health states on a monthly basis over a 5-year time horizon. As therapeutic strategies, PLAI, quetiapine, risperidone long-acting injections (RLAI), oral olanzapine, oral risperidone, zuclopenthixol decanoate, olanzapine long-acting injections (OLAI), oral typical and oral atypical were compared. Probability of relapse, level of adherence, side effects and treatment discontinuation were derived from the Swedish original model. Input factors regarding resource use and costs were estimated and adjusted for the German healthcare system. A probabilistic sensitivity analyses (PSA) using cost-effectiveness scatter plots was performed to visualize the robustness of the results.

RESULTS

In base-case scenario, PLAI is superior to RLAI in gained quality-adjusted life-years (QALYs) and avoided relapses. Relative to all other treatment strategies, PLAI is more effective with regard to gained QALYs and avoided relapses but results in higher treatment costs over a 5-year horizon in base-case scenario. The results were tested in PSA. If a cost-effectiveness threshold of <euro>30,000 is assumed, for example, PLAI can be considered to be cost effective compared with RLAI in about 92.5 % of cases regarding gained QALYs, and in 78.6 % of cases regarding avoided relapse. Compared with OLAI, in about 94.4 % of cases regarding gained QALYs and in 99.9 % of cases regarding avoided relapse, cost effectiveness can be considered. Comparing PLAI and zuclopenthixol decanoate, cost effectiveness can be assumed in about 90.4 % of cases regarding gained QALYs, and in all cases regarding avoided relapse.

CONCLUSIONS

PLAI dominates RLAI and compared with the other treatment strategies PLAI has shown to be more effective but results in higher costs in base-case scenario.

Patients' and clinicians' attitude towards long-acting depot antipsychotics in subjects with a first episode of psychosis

OBJECTIVES

The acceptance and use of long-acting depot antipsychotics has been shown to be influenced by the attitudes of patients and clinicians. Depot treatment rates are low across countries and especially patients with first-episode psychosis are rarely treated with depot medication. The aim of this article was to review the literature on patients' and clinicians' attitudes towards long-acting depot antipsychotics in subjects with first-episode psychosis.

METHODS

A systematic search of Medline, Embase, PsycINF and Google Scholar was conducted. Studies were included if they reported original data describing patients' and clinicians' attitudes towards long-acting depot antipsychotic in subjects with first-episode psychosis.

RESULTS

Six studies out of a total of 503 articles met the inclusion criteria. Four studies conveyed a negative and two a positive opinion of clinicians toward depot medication. No systematic study directly addressed the attitude of patients with first-episode psychosis. Psychiatrists frequently presume that patients with first-episode psychosis would not accept depot medication and that depots are mostly eligible for chronic patients.

CONCLUSIONS

Full information of all patients especially those with first episode psychosis in a therapeutic relationship that includes shared decision-making processes could reduce the negative image and stigmatization attached to depots.

Reducing seclusion through involuntary medication: a randomized clinical trial

The study evaluated whether seclusion and coercive incidents would be reduced in extent and number if involuntary medication was the first choice of intervention. Patients admitted to an acute psychiatric ward were randomly allocated to two groups. In Group 1, involuntary medication was the intervention of first choice for dealing with agitation and risk of violence. In Group 2, seclusion was the intervention of first choice. Patients' characteristics between the groups were compared by Pearson χ(2) and two-sample t-tests; the incidence rates and risk ratios (RRs) were calculated to examine differences in number and duration of coercive incidents. In Group 1, the relative risk of being secluded was lower than in Group 2, whereas the risk of receiving involuntary medication was higher. However, the mean duration of the seclusion incidents did not differ significantly between the two groups; neither did the total number of coercive incidents. Although the use of involuntary medication could successfully replace and reduce the number of seclusions, alternative interventions are needed to reduce the overall number and duration of coercive incidents. A new policy for managing acute aggression - such as involuntary medication - can be implemented effectively only if certain conditions are met.

Working alliance and its relationship to outcomes in a randomized controlled trial (RCT) of antipsychotic medication

BACKGROUND

Long acting injections (LAI) have been associated with perceptions of coercion in cross sectional studies but there have been no longitudinal studies of the effects on clinical relationships with newer depot medications.

METHOD

Randomized controlled trial with (50) participants with a diagnosis of schizophrenia randomized to risperidone LAI or oral atypical antipsychotic medication. The main outcome was the Working Alliance Inventory (WAI) with background variables (symptoms, side effect, social functioning, quality of life) measured before randomization and at two years.

RESULTS

At follow-up (14 risperidone LAI and 16 oral medication) analyses including predictors of missing data and baseline score showed a trend for those on risperidone LAI to reduce WAI score and those on oral medication showing no change. Sensitivity analyses showed (i) a significant detrimental effect of LAI on WAI and (ii) the pattern of results was not affected by change in symptoms over the study.

CONCLUSION

This is the first study to show that the prescription of depot atypical depot medication is associated with detrimental effects on clinical relationships after 2 years of continual treatment.

The knowledge and attitudes of psychiatrists towards antipsychotic long-acting injections in Nigeria

BACKGROUND

Antipsychotic long-acting injections (LAIs) reduce covert nonadherence with medication in the clinical management of psychotic disorders. However, they are variably utilised by clinicians, especially in the long term. Factors including poor knowledge, stigma and perceived coercion can all adversely influence LAI utilisation. Previous research has emanated almost exclusively from developed countries. This study explores the knowledge and attitudes of psychiatrists and trainees in Nigeria towards LAIs.

METHODS

A cross-sectional study was undertaken among mental health professionals in Nigeria using a pre-existing questionnaire.

RESULTS

Participant psychiatrists (n = 128) expressed positive attitudes towards LAIs. Their knowledge concerning LAIs and its side effects was fair. The participants reported that nearly half (41.7%) of their patients with a psychotic illness were on LAIs. Those who reported a high prescribing rate for LAIs (>40%) were more likely to endorse more positive 'patient-centred attitudes' (p < 0.04). In contrast to previous reports, psychiatrists reported that patients were less likely to feel ashamed when on LAIs, though most endorsed the statement that force was required during LAI administration.

CONCLUSION

The desirability of treatment by injections differs in Africa in comparison to Western cultures, possibly due to the increased potency that injections are perceived to have. This is perhaps evidenced by high rates reported for use of LAIs. Nigerian psychiatrists had positive attitudes to LAIs but their knowledge, particularly regarding side effects, was fair and needs to be improved. Providing information to patients prior to antipsychotic treatment may enhance informed consent in a country where medical paternalism is still relatively strong.

Prevalence of concomitant oral antipsychotic drug use among patients treated with long-acting, intramuscular, antipsychotic medications

OBJECTIVE

Long-acting injectable (LAI) antipsychotic drugs are viewed as monotherapeutic alternatives to oral medications to promote medication adherence, but there have been no descriptive studies of concomitant use of oral and LAI medications.

METHODS

A list of all patients receiving services from the Connecticut Mental Health Center from July 1, 2009, to June 30, 2010, was obtained from center administrative records, and those carrying an initial intake diagnosis of schizophrenia or schizoaffective disorder were identified. All team leaders were approached, and all clinicians were asked to identify patients on their case load prescribed LAIs during the time interval above. Also, all internal and external pharmacy orders were reviewed. Concomitancy was defined as simultaneous oral and LAI antipsychotic use at any time from July 1, 2009, to June 30, 2010. Data were culled from the medical records using a form (available on request) that recorded current LAI antipsychotic, reasons for LAI use, length of time on LAI, monthly dosage, and all concomitant oral antipsychotics, antidepressants, and anxiolytic agents.

RESULTS

Among 124 patients on LAI medications, 57 (46%) received concomitant oral and LAI antipsychotics: 27 (47%) were prescribed LAI haloperidol, 19 (33%) LAI fluphenazine, and 11 (19%) risperidone microspheres. Logistic regression showed greater use of oral antipsychotic for both Hispanic ethnicity (odds ratio, 3.8; 95% confidence interval, 1.3-10.8) and alcohol abuse/dependence (odds ratio, 6.5; 95% confidence interval, 1.3-31.9), with no significant differences on other variables. There were no significant differences between LAI agents in rates of use of concomitant oral antipsychotic, anticholinergic, sedative/hypnotic, or mood stabilizer. Patients were more likely to be prescribed concomitant oral preparations of their LAI agent than another oral antipsychotic. Higher dosing of LAI treatments was associated with a significantly greater likelihood of use of oral psychotropics and anticholinergics.

CONCLUSIONS

Almost one half of patients prescribed LAI antipsychotics receive oral antipsychotics and other oral psychotropics. This challenges the notion that LAIs are used as monotherapy in real-world settings. Concomitant oral and LAI antipsychotic prescriptions may represent a common practice of polypharmacy that merits further investigation.

Evaluation of behavioral changes and subjective distress after exposure to coercive inpatient interventions

BACKGROUND

There is a lack of evidence to underpin decisions on what constitutes the most effective and least restrictive form of coercive intervention when responding to violent behavior. Therefore we compared ratings of effectiveness and subjective distress by 125 inpatients across four types of coercive interventions.

METHODS

Effectiveness was assessed through ratings of patient behavior immediately after exposure to a coercive measure and 24 h later. Subjective distress was examined using the Coercion Experience Scale at debriefing. Regression analyses were performed to compare these outcome variables across the four types of coercive interventions.

RESULTS

Using univariate statistics, no significant differences in effectiveness and subjective distress were found between the groups, except that patients who were involuntarily medicated experienced significant less isolation during the measure than patients who underwent combined measures. However, when controlling for the effect of demographic and clinical characteristics, significant differences on subjective distress between the groups emerged: involuntary medication was experienced as the least distressing overall and least humiliating, caused less physical adverse effects and less sense of isolation. Combined coercive interventions, regardless of the type, caused significantly more physical adverse effects and feelings of isolation than individual interventions.

CONCLUSIONS

In the absence of information on individual patient preferences, involuntary medication may be more justified than seclusion and mechanical restraint as a coercive intervention. Use of multiple interventions requires significant justification given their association with significant distress.

Addressing non-adherence to antipsychotic medication: a harm-reduction approach

This paper discusses the evidence base for interventions addressing non-adherence to prescribed antipsychotics. A case study approach is used, and the extent to which adherence improvement interventions might be used in collaboration with a specific patient is considered. The principles and application of harm-reduction philosophy in mental health are presented in a planned non-adherence harm-reduction intervention. This intervention aims to acknowledge the patient's ability to choose and learn from experience and to reduce the potential harm of antipsychotic withdrawal. The intervention evaluation method is outlined.

Paliperidone palmitate injection for the acute and maintenance treatment of schizophrenia in adults

PURPOSE

To review the use of paliperidone palmitate in treatment of patients with schizophrenia.

METHODS

Published clinical trial data for the development and utilization of paliperidone palmitate for the treatment of schizophrenia were assessed in this review. Four short-term, randomized, double-blind, placebo-controlled trials investigated the efficacy of paliperidone palmitate in acute exacerbation of schizophrenia. Paliperidone palmitate was also studied as a maintenance treatment to prevent or delay relapse in stable schizophrenia. In addition, paliperidone palmitate was compared to risperidone long-acting injection for noninferiority in three studies.

RESULTS

Paliperidone palmitate has been shown to be effective in reducing symptoms as measured by the Positive and Negative Syndrome Scale total scores in the four acute treatment studies. In the maintenance treatment studies, paliperidone palmitate was found to be more effective than placebo in preventing or delaying the time to first relapse in stable schizophrenia patients. In addition, paliperidone palmitate was shown to be noninferior to risperidone long-acting injection in two studies. It was shown to be reasonably well tolerated in all clinical trials. Acute treatment phase should be initiated with a dose of 234 mg on day one and 156 mg on day eight, followed by a recommended monthly maintenance dose of 39-234 mg based on efficacy and tolerability results from the clinical studies.

CONCLUSION

Providing an optimal long-term treatment can be challenging. Paliperidone palmitate can be used as an acute treatment even in outpatient setting, and it has shown to be well tolerated by patients. Also, it does not require overlapping oral antipsychotic supplementation while being initiated, and is dosed once per month.

Patient and Health Care Provider Perspectives on Long Acting Injectable Antipsychotics in Schizophrenia and the Introduction of Olanzapine Long-Acting Injection

Olanzapine long acting injection has joined risperidone and paliperidone as the second generation long acting antipsychotic injection options for treatment of patients with schizophrenia. Long acting injections are important alternatives to oral medications for patients who have difficulty adhering to daily or multiple daily medication administrations, yet may be underutilized or not well understood. Patient perceptions, adherence, and preferences are important issues for health care providers to address when discussing treatment options with their patients. Reviewed here are overall patient and health care provider attitudes and perceptions regarding long acting injections and the details of olanzapine long acting injectable, the newest agent, and how it will fit in the marketplace. In addition, efficacy, safety, dosing and use data regarding this newest long acting agent are reviewed and compared to other available long acting agents.

Patient perspectives in the development and use of long-acting antipsychotics in schizophrenia: focus on olanzapine long-acting injection

Schizophrenia is a chronic mental disorder generally treated with antipsychotic medication. However, non-adherence and partial adherence to antipsychotic medication treatment is common and long-acting injectable "depot" preparations of antipsychotic medications have been used as an alternative to oral medication therapy for patients for whom adherence is a clinically significant problem, as well as for the sake of convenience and in response to patient preference. Olanzapine long-acting injection (OLAI) is a new treatment option and has been approved by several regulatory agencies for the treatment of schizophrenia. OLAI is a crystalline salt formulation of olanzapine and pamoic acid. Efficacy was established in 2 double-blind randomized clinical trials of OLAI for the treatment of acute schizophrenia and for the maintenance of response. The therapeutic OLAI dosages are 150 mg q2 weeks, 210 mg q2 weeks, 300 mg q2 weeks or q4 weeks, and 405 mg q4 weeks, administered by deep intramuscular gluteal injection with a 19-gauge needle. Injection volume ranges from 1 to 2.7 mL. OLAI has essentially the same general tolerability as that of oral olanzapine; however with the depot there is the additional risk of a post-injection delirium sedation syndrome occurring at a rate of 0.07% of injections, requiring a risk management plan that includes observing the patient for 3 hours post injection.
