Adesão ao tratamento medicamentoso em pacientes do espectro esquizofrênico: uma revisão sistemática da literatura

Homelessness and health-related outcomes: an umbrella review of observational studies and randomized controlled trials

BACKGROUND

Homelessness has been associated with multiple detrimental health outcomes across observational studies. However, relatively few randomized controlled trials (RCTs) have been conducted on people who experience homelessness (PEH). Thus, this umbrella review ranked the credibility of evidence derived from systematic reviews (SRs) and meta-analyses (MAs) of observational studies investigating the associations between homelessness and any health outcome as well as RCTs targeting health needs in this population.

METHODS

Several databases were systematically searched from inception through April 28, 2021. Any SR and/or MA reporting quantitative data and providing a control group were eligible for inclusion. The credibility of the evidence derived from observational studies was appraised by considering the significance level of the association and the largest study, the degree of heterogeneity, the presence of small-study effects as well as excess significance bias. The credibility of evidence was then ranked in five classes. For SRs and/or MAs of RCTs, we considered the level of significance and whether the prediction interval crossed the null. The AMSTAR-2 and AMSTAR-plus instruments were adopted to further assess the methodological quality of SRs and/or MAs. The Newcastle-Ottawa Scale (NOS) was employed to further appraise the methodological quality of prospective cohort studies only; a sensitivity analysis limited to higher quality studies was conducted.

RESULTS

Out of 1549 references, 8 MAs and 2 SRs were included. Among those considering observational studies, 23 unique associations were appraised. Twelve of them were statistically significant at the p≤0.005 level. Included cases had worst health-related outcomes than controls, but only two associations reached a priori-defined criteria for convincing (class I) evidence namely hospitalization due to any cause among PEH diagnosed with HIV infection, and the occurrence of falls within the past year among PEH. According to the AMSTAR-2 instrument, the methodological quality of all included SRs and/or MAs was "critically low." Interventional studies were scant.

CONCLUSION

While homelessness has been repeatedly associated with detrimental health outcomes, only two associations met the criteria for convincing evidence. Furthermore, few RCTs were appraised by SRs and/or MAs. Our umbrella review also highlights the need to standardize definitions of homelessness to be incorporated by forthcoming studies to improve the external validity of the findings in this vulnerable population.

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.

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.

An Integrative Review of Non-Pharmacological Therapeutic Interventions in Children with Mental Health Problems

We provide an integrative review of non-pharmacological interventions for children with mental health problems. A total of 262 studies were found in three databases, of which 12 met the inclusion criteria, indicating a shortage of research on the subject. The most frequently used type of intervention was cognitive-behavioural therapy-based interventions, and attention deficit hyperactivity disorder was the most frequent problem. Non-pharmacological interventions help to improve the symptoms of childhood mental health problems, so there is a need to carry out further research on this issue in Brazil and the rest of Latin America.

Adaptation and validation of the Measuring of Treatment Adherence for mental health

OBJECTIVE

to adapt culturally and validate the Measuring Instrument of Treatment Adherence for mental health.

METHOD

methodological study, carried out with 300 individuals with mental disorders, in two Psychosocial Care Centers in Curitiba, state of Paraná, Brazil, from April to June 2014. The cross-cultural adaptation was developed according to international recommendations, the construct validation was made by exploratory factor analysis, and internal consistency was verified by Cronbach's alpha.

RESULTS

through the evaluation of a committee of experts and completion of the pre-testing, face and content validation was achieved. From the factor analysis, we identified two factors of the instrument's construct: involuntary action and voluntary action, with a total explanation variance of 55.7%. The value of Bartlett's test of sphericity was p<0.001. Cronbach's alpha was 0.74.

CONCLUSION

the adapted and validated instrument proved to be trustworthy to be applied to the verification of adherence to drug therapy for individuals with mental disorders.

Adherence of mental therapy for mental disorder patients to drug health treatment [corrected]

OBJECTIVE

To assess the adherence of mental disorder patients to drug therapy for mental health treatment and the association between demographic, socioeconomic, clinical and pharmacotherapeutic variables to treatment adherence.

METHOD

A cross-sectional study conducted with mental disorder patients in two Psychosocial Care Centers in Curitiba/Paraná in 2014. Data from structured interviews and medical records were submitted to descriptive and bivariate analysis.

RESULTS

300 patients with mental disorders participated in the study. 51% of participants adhered to the drug therapy, the highest adherence was among males with no family history of mental disorder, diagnosed with schizophrenia, with disease duration of less than 1 year, who did not forget to take the medicine not even once in the previous month and who relied on family participation. Adherence was lower among the interviewees with individual income lower than one minimum wage, perception of regular and poor health, diagnosis of depression associated with another disorder, treatment time in the service over 2 years and with a history of attempted suicide.

CONCLUSION

Low adherence to the drug therapy was observed. The variables associated with adherence were gender, individual income, family history of mental disorder, perception about their health, diagnosis of mental disorder, duration of illness and treatment, suicide attempt, failing to take the medication at least once in the previous month and family participation.

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.
