Australian case managers' views about the impact of antipsychotic medication on mental health consumers

Impact of adverse reactions to first-generation antipsychotics on treatment adherence in outpatients with schizophrenia: a cross-sectional study

BACKGROUND

Antipsychotics are well-known to cause potentially serious and life-threatening adverse drug reactions (ADRs) that have been reported to be also one of the major reasons for non-adherence. In Eritrea, shortage of psychiatrists and physicians, inadequacy of laboratory setups and unavailability of second-generation antipsychotics in the national list of medicines would seem to amplify the problem. This study's objective is to determine the impact of adverse effects of first-generation antipsychotics on treatment adherence in outpatients with schizophrenia at Saint Mary Neuro-Psychiatric National Referral Hospital.

METHODS

A cross-sectional study design was employed. All eligible adult patients with diagnosed schizophrenia (n = 242) who visited the hospital during the study period were enrolled. Data on ADRs, adherence and other variables were collected from patients using a self-administered questionnaire, interview and through medical cards review. The collected variables were analyzed using SPSS 22.0 with descriptive and multivariable logistic regression analysis. Statistical significance was tested at p value < 0.05.

RESULTS

Greater than one-third (35.5%) of the patients with schizophrenia were non-adherent to treatment. The odds of non-adherence increased 1.06 times for each unit increase in the total ADR score (AOR = 1.06, 95% CI 1.04, 1.09). Patients with extrapyramidal (AOR = 44.69, 95% CI 5.98, 334.30), psychic (AOR = 14.90, 95% CI 1.90, 116.86), hormonal (AOR = 2.60, 95% CI 1.41, 4.80), autonomic (AOR = 3.23, 95% CI 1.37, 7.57) and miscellaneous reactions (AOR = 2.16, 95% CI 1.13, 4.13) were more likely to be non-adherent compared to their counterparts.

CONCLUSION

Poor treatment adherence was found to be substantial which was attributed to total ADR score, extrapyramidal, hormonal, psychic, autonomic and miscellaneous categories of reactions of the LUNSERS. To improve treatment adherence, early detection and management of adverse effects and inclusion of second-generation antipsychotics are recommended.

Magnitude, Nature, and Risk Factors of Adverse Drug Reactions Associated with First Generation Antipsychotics in Outpatients with Schizophrenia: A Cross-Sectional Study

Background

ADRs to antipsychotics are amongst the major challenges in the treatment of patients with psychotic disorders. The extent of patient-reported ADRs assessed in many studies using standardized scales is found to be inconsistent. However, there is a paucity of such research in Eritrea. The aim of the study is therefore to determine the magnitude, nature, and the possible risk factors associated with ADRs of the first generation antipsychotics in outpatients with schizophrenia at Saint Mary Neuro-Psychiatric National Referral Hospital in Asmara, Eritrea, using the LUNSERS self-rating scale.

Methods

A cross-sectional, descriptive and analytical study design utilizing a quantitative approach was employed. Data were collected from patients' self-administered questionnaires, interviews, and medical records. The collected variables were analyzed using SPSS 22.0 with descriptive statistics, correlation, t-tests, ANOVA, and multiple regression. Statistical significance was tested at P-value<0.05.

Results

In this study, 93.8% of the research participants experienced at least one ADR. LUNSERS total mean score of the relevant items was 28.01 (SD=18.46) with 24.7% of the study participants scoring medium-to-high. The prevalence of the categories of ADRs was psychic (91.3%), autonomic (78.1%), extra-pyramidal (76.9%), miscellaneous (66.5%), hormonal (58.3%), anti-cholinergic (44.2%), and allergic reactions (44.2%). At multivariate level, factors significantly and positively associated with total ADR score were smoking (P=0.028) and being at secondary educational level (P=0.015).

Conclusion

There was high prevalence of ADRs with moderate-to-high overall ADR scores in a significant number of patients. The most frequently reported ADRs were psychic, autonomic, extra-pyramidal, hormonal, and miscellaneous. Smoking and secondary level of education were found to be the main determinants of ADRs.

Antipsychotic drug use in pregnancy: A multinational study from ten countries

AIM

To compare the prevalence and trends of antipsychotic drug use during pregnancy between countries across four continents.

METHODS

Individually linked health data in Denmark (2000-2012), Finland (2005-2014), Iceland (2004-2017), Norway (2005-2015), Sweden (2006-2015), Germany (2006-2015), Australia (New South Wales, 2004-2012), Hong Kong (2001-2015), UK (2006-2016), and the US (Medicaid, 2000-2013, and IBM MarketScan, 2012-2015) were used. Using a uniformed approach, we estimated the prevalence of antipsychotic use as the proportion of pregnancies where a woman filled at least one antipsychotic prescription within three months before pregnancy until birth. For the Nordic countries, data were meta-analyzed to investigate maternal characteristics associated with the use of antipsychotics.

RESULTS

We included 8,394,343 pregnancies. Typical antipsychotic use was highest in the UK (4.4%) whereas atypical antipsychotic use was highest in the US Medicaid (1.5%). Atypical antipsychotic use increased over time in most populations, reaching 2% in Australia (2012) and US Medicaid (2013). In most countries, prochlorperazine was the most commonly used typical antipsychotic and quetiapine the most commonly used atypical antipsychotic. Use of antipsychotics decreased across the trimesters of pregnancy in all populations except Finland. Antipsychotic use was elevated among smokers and those with parity ≥4 in the Nordic countries.

CONCLUSION

Antipsychotic use during pregnancy varied considerably between populations, partly explained by varying use of the typical antipsychotic prochlorperazine, which is often used for nausea and vomiting in early pregnancy. Increasing usage of atypical antipsychotics among pregnant women reflects the pattern that was previously reported for the general population.

Prevalence and management practice of first generation antipsychotics induced side effects among schizophrenic patients at Amanuel Mental Specialized Hospital, central Ethiopia: cross-sectional study

BACKGROUND

First-generation antipsychotics (FGAs) are associated with a range of adverse events which can significantly reduce patients' quality of life and contribute to non-adherence. The aim of this study was to assess the prevalence and management practice of first generation antipsychotics induced side effects among schizophrenic patients.

METHODS

The study was conducted at Amanuel Mental Specialized Hospital from March to June, 2017. Data from patients were collected using a pretested structured questionnaire. Demographics and side effects of antipsychotics were collected by face to face interview. Clinical characteristics, medications and previous history of adverse drug events were extracted from medical records using data abstraction format. The data were analyzed using statistical software for social sciences (SPSS) version 20. Descriptive statistics and chi-square tests were done. Statistical significance was considered at p < 0.05.

RESULTS

Out of 356 participants, 300 of them had complete data and were included in the study. The mean age of participants was 33.71 ± 10.2 years. The majority, 195(65.0%), of participants were males. Most of the participants, 293(97.7%), developed FGA medication induced side effects. One hundred sixty three (54.3%) participants were treated with Trihexyphenidyl for FGAs induced side effects. Dose reduction of antipsychotics was done for 51(17.0%) participants. Most of the participants' side effects were not managed according to American Psychiatric Association guideline; 178 (82.4%). The most common types of FGAs induced side effects were cardiovascular side effects 169(56.3%); sedation and CNS side effects 149(49.6%); and extrapyramidal side effects 114(38.0%). There is a significant association between occurrence of side effects of FGAs and duration of illness (P = 0.04).

CONCLUSIONS

The prevalence of first generation antipsychotics induced side effects was high. However, management practice of the side effects was minimal.

Mental Health Consumers' Motives for Seeking Advocacy Support: A Qualitative Exploration

Advocacy plays a vital role in ensuring that mental health consumers' rights are maintained. However, the primary issues for which consumers seek advocacy support remain unknown. Understanding these issues provides a sound basis from which advocacy organisations may develop a clear service delivery focus. This study addresses the literature gap through presenting a qualitative analysis of 60 records from an advocacy service. Four major themes emerged, across which two key issues were dominant: the sense of fearfulness and disempowerment. These issues accentuate the importance of advocates in enhancing the agency of mental health consumers.

Participation in mental healthcare: a qualitative meta-synthesis

Background

Facilitation of service user participation in the co-production of mental healthcare planning and service delivery is an integral component of contemporary mental health policy and clinical guidelines. However, many service users continue to experience exclusion from the planning of their care. This review synthesizes qualitative research about participation in mental healthcare and articulates essential processes that enable service user participation in mental health care.

Methods

Electronic databases were systematically searched. Studies were included if they were peer reviewed qualitative studies, published between 2000 and 2015, examining participation in mental health care. The Critical Appraisal Skills Program checklist was used to assess the quality of each included study. Constant comparison was used to identify similar constructs across several studies, which were then abstracted into thematic constructs.

Results

The synthesis resulted in the identification of six principal themes, which articulate key processes that facilitate service user participation in mental healthcare. These themes included: exercising influence; tokenism; sharing knowledge; lacking capacity; respect; and empathy.

Conclusions

This meta-synthesis demonstrates that service user participation in mental healthcare remains a policy aspiration, which generally has not been translated into clinical practice. The continued lack of impact on policy on the delivery of mental healthcare suggests that change may have to be community driven. Systemic service user advocacy groups could contribute critically to promoting authentic service user participation in the co-production of mental health services.

Carers' involvement in decision making about antipsychotic medication: A qualitative study

Background

Current Australian mental health policy recommends that carers should be involved in the provision of mental health services. Carers often provide intensive support to mental health consumers and gain detailed insight into their lives. As such, carers could make valuable contributions to well‐informed decisions about mental health consumers' use of antipsychotic medication.

Objectives

The aim of this study was to explore carers' participation in antipsychotic medication decision making.

Methods

Snowball sampling was used to enrol 29 carers in this study. Of these carers, 19 participated in semi‐structured interviews, and ten participated in a focus group. Data were analysed thematically.

Results

Four main themes emerged from the analysis. The findings highlighted that carers typically received little or no information about antipsychotic medication. Carers commonly addressed the shortfall in information by obtaining additional information through online sources or distributing among carer networks material that they had developed themselves. Almost all carers emphasized that they should be involved in decisions about antipsychotic medication, but noted that they were typically excluded. The lack of involvement in medication decisions was a source of frustration, as carers could contribute saliently through sharing detailed knowledge about mental health consumers' lives, address communication gaps that resulted from disjointed care and improve communication between health professionals and mental health consumers.

Conclusion

Health professionals could consider improving the extent to which they collaborate with carers in medication decisions.

Antipsychotic medication side effect assessment tools: A systematic review

OBJECTIVE

The aim of this systematic review was to critically appraise the psychometric properties of antipsychotic medication side effect assessment tools.

METHODS

Systematic searches were undertaken in PubMed, CINAHL and CENTRAL from inception to October 2014. Studies were included if they detailed the evaluation of psychometric properties of antipsychotic medication side effect assessment tools in mental health populations. Studies were excluded if they examined the use of antipsychotic medication side effect assessment tools in non-mental health populations, including people suffering from dementia, Parkinsonism and Alzheimer's. Narrative reviews and studies published in any language other than English were also excluded.

RESULTS

Content validity was appropriately established for only one of the tools, reliability was inappropriately evaluated for all but one tool, and the assessment of responsiveness was not acceptable for any tool.

CONCLUSION

Further psychometric studies are warranted to consolidate the psychometric properties of the included antipsychotic medication side effect assessment tools before any of these tools can be confidently recommended for either research or clinical purposes.
