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.

Evaluation of nonadherence to treatment among patients with schizophrenia attending psychosocial care centers in the south region of Brazil

Introduction

The treatment of schizophrenia aims to reduce symptoms, improve quality of life and promote recovery from debilitating effects. Nonadherence to treatment is related to several factors and may lead to persistence of symptoms and relapse. Worldwide, the rate of nonadherence to treatment in individuals with schizophrenia is around 50%.

Objectives

To compare the clinical profile of nonadherent and adherent patients among individuals diagnosed with schizophrenia receiving treatment at psychosocial care centers in a city in southern Brazil.

Method

The clinical-epidemiological profile of patients with schizophrenia was retrospectively analyzed based on medical records entered into the system between January and December 2016, evaluating data at one-year follow-up.

Results

112 patients were included. The disease was more prevalent in men; mean age was 40.5 years, being lower among men. Most of the sample had a low level of education, was unemployed/retired, did not have children and resided with relatives. The highest rate of diagnosis was among young adults. Psychotic symptoms were most frequently described, and the most commonly prescribed antipsychotic was haloperidol. The nonadherence rate was 15.2%; only one patient required admission to a psychiatric hospital. Among nonadherent patients, the mean time of attendance was 6 months; there were more nonadherent women than men. The most prevalent age range of nonadherence was 41-64 years. Psychosocial and clinical data were similar across the whole sample.

Conclusion

A nonadherence rate of 15.2% was found among individuals receiving treatment for schizophrenia, suggesting that psychosocial care centers were effective in treating and monitoring these patients.

Psychological factors involved in psychopharmacological medication adherence in mental health patients: A systematic review

BACKGROUND

Psychopharmacological medication adherence is essential for psychiatric patients' treatment and well-being.

OBJECTIVE

This review aimed to identify psychological factors related to health control that have been linked to psychopharmacological medication adherence in psychiatric patients.

METHODS

A literature search was performed through the databases Medline, PubMed, PsycINFO, and Google Scholar to identify relevant studies published before October 15th, 2019. Articles published in peer-reviewed journals that analyzed the psychological factors of health belief and health control involved in psychopharmacological medication adherence in a psychiatric population were included.

RESULTS

The search identified 124 potentially relevant papers, 29 of which met the eligibility criteria. The final sample was 222 adolescents, most with a diagnosis of attention deficit/hyperactivity disorder (ADHD), and 6139 adults diagnosed especially with schizophrenia spectrum disorder, bipolar disorder, or depressive disorder. Results suggested that medication adherence is associated with health beliefs and psychological variables, such as self-efficacy and locus of control. Family support was also positively related to medication adherence.

CONCLUSION

Psychopharmacological medication adherence requires a consideration of multicausality, which depends on sociodemographic, clinical, and psychological factors.

PRACTICE IMPLICATIONS

These findings should be considered in the development and implementation of psychological interventions focused on self-control and family support.

Antipsychotic medication non-adherence among schizophrenia patients in Central Ethiopia

Background

Despite the fact that adherence to antipsychotic medications is the cornerstone in the treatment and prevention of relapse of the disease, non-adherence is a major problem among schizophrenia patients. The purpose of this study was to assess the magnitude and factors associated with antipsychotic medication non-adherence among schizophrenia patients in Amanuel Mental Specialized Hospital.

Method

An institution-based cross-sectional study was conducted among 412 people with schizophrenia at Amanuel Mental Specialized Hospital from April to May 2014. Non-adherence was assessed using the questionnaire of Morisky medication adherence rating scale and semi-structured questions for assessment of associated factors. Logistic regression analysis was used to assess predictors of non-adherence.

Results

Prevalence of non-adherence was 41.0% among schizophrenia patients. Living in rural areas (adjusted odds ratio [AOR] = 2.07; 95% confidence interval [CI]: 1.31, 3.28), current substance use (AOR = 1.67; 95% CI: 1.09, 2.56), long duration of treatment (AOR = 2.07; 95% CI: 1.22, 3.50) and polypharmacy (AOR = 2.13; 95% CI: 1.34, 3.40) were found to be significantly associated with non-adherence.

Conclusion

The results indicate that non-adherence to antipsychotic medication was a major problem among patients with schizophrenia. Reducing the number of antipsychotic medications and availing drugs in rural areas may decrease the level of non-adherence.

The meaning of pharmacological treatment for schizophrenic patients

OBJECTIVE:

to understand the meaning of medication therapy for schizophrenic patients and formulate a theoretical model about the study phenomenon.

METHOD:

a qualitative approach was employed, using Symbolic Interactionism as the theoretical and Grounded Theory as the methodological framework. The research was developed between 2008 and 2010 at three community mental health services in the interior of the State of São Paulo - Brazil. Thirty-six patients and thirty-six family members were selected through theoretical sampling. The data were mainly collected through open interviews and observation and simultaneously analyzed through open, axial and selective coding.

RESULTS:

the meaning of the pharmacotherapy is centered on the phenomenon "Living with a help that bothers", which expresses the patients' ambivalence towards the medication and determines their decision making. The insight, access, limitations for self-administration of the drugs and interactions with family members and the health team influenced the patient's medication-related behavior.

CONCLUSION:

the theory presented in this study provides a comprehensive, contextualized, motivational and dynamic understanding of the relation the patient experiences and indicates potentials and barriers to follow the medication treatment.

[Antidepressants: use, adherence and awareness among medical students]

This study assessed the degree of adherence and drug-related awareness and opinions regarding the importance of guidance with respect to treatment among medical students who use antidepressants. It is a cross-sectional descriptive study, carried out in a public Medical School in the state of Sao Paulo, Brazil. Of the 289 students interviewed, 33 (11.4%) use or had already used antidepressants, with fluoxetine being the most prescribed. The nurse was not cited as being responsible for guidance on the antidepressant. Although most students had received guidance on antidepressants, they did not heed guidance and still had doubts regarding their use. There was a statistically significant association regarding the consumption of other drugs in addition to antidepressants and the existence of side effects, as well as regarding an increase of the dosage without medical consultation and the existence of such side effects. Actions are necessary to acknowledge the importance of the teaching of psychopharmacology in the training of the medical professional and for greater harmony between theory and practice.

Qualidade do cuidado em dois centros de atenção psicossocial sob o olhar de usuários

Esta investigação objetivou compreender experiências de usuários em dois Centros de Atenção Psicossocial (CAPS), localizados em Fortaleza, Ceará, no que concerne à qualidade do cuidado conferido pelos profissionais. O estudo foi conduzido mediante uma abordagem qualitativa, alinhada à vertente hermenêutico-crítica, tendo empregado como técnicas para a obtenção do material empírico a entrevista não estruturada e a observação sistemática. O processamento e interpretação do material discursivo evidenciaram três dimensões analíticas relativas ao tema Qualidade do Cuidado, categorizadas conforme segue: a) aspectos formais da assistência; b) humanização e acolhimento; e c) integralidade e clínica ampliada. Os usuários percebem o acolhimento, a ambiência, a boa interação entre profissionais e usuários, o monitoramento medicamentoso e a humanização como os principais elementos que conferem o estatuto de atendimento de qualidade em saúde mental. Conclui-se que, não obstante a presença de entraves, os aspectos da assistência apontados pelos usuários dos dispositivos analisados corroboram os ideais da Reforma Psiquiátrica e sinalizam que a reorientação do modelo de atenção em saúde mental já se capilariza no cotidiano das práticas de cuidado.
