RESUMO
BACKGROUND: Determining the mental capacity of psychiatric patients for making healthcare related decisions is crucial in clinical practice. This meta-review of review articles comprehensively examines the current evidence on the capacity of patients with a mental illness to make medical care decisions. METHODS: Systematic review of review articles following PRISMA recommendations. PubMed, Scopus, CINAHL and PsycInfo were electronically searched up to 31 January 2020. Free text searches and medical subject headings were combined to identify literature reviews and meta-analyses published in English, and summarising studies on the capacity of patients with serious mental illnesses to make healthcare and treatment related decisions, conducted in any clinical setting and with a quantitative synthesis of results. Publications were selected as per inclusion and exclusion criteria. The AMSTAR II tool was used to assess the quality of reviews. RESULTS: Eleven publications were reviewed. Variability on methods across studies makes it difficult to precisely estimate the prevalence of decision-making capacity in patients with mental disorders. Nonetheless, up to three-quarters of psychiatric patients, including individuals with serious illnesses such as schizophrenia or bipolar disorder may have capacity to make medical decisions in the context of their illness. Most evidence comes from studies conducted in the hospital setting; much less information exists on the healthcare decision making capacity of mental disorder patients while in the community. Stable psychiatric and non-psychiatric patients may have a similar capacity to make healthcare related decisions. Patients with a mental illness have capacity to judge risk-reward situations and to adequately decide about the important treatment outcomes. Different symptoms may impair different domains of the decisional capacity of psychotic patients. Decisional capacity impairments in psychotic patients are temporal, identifiable, and responsive to interventions directed towards simplifying information, encouraging training and shared decision making. The publications complied satisfactorily with the AMSTAR II critical domains. CONCLUSIONS: Whilst impairments in decision-making capacity may exist, most patients with a severe mental disorder, such as schizophrenia or bipolar disorder are able to make rational decisions about their healthcare. Best practice strategies should incorporate interventions to help mentally ill patients grow into the voluntary and safe use of medications.

Twenty seven obsessive-compulsive disorder (OCD) patients were studied at the Instituto Mexicano de Psiquiatría in Mexico City. This is the first sample of OCD patients studied in Latin America. There was a significant sex ratio difference and a significant difference in the type of obsessions and compulsions displayed by males and females. Co-morbidity data demonstrated a high frequency of obsessive-compulsive personality disorders, depression, sexual abuse, suicidal attempts and neurological damage. Approximately one third of OCD cases demonstrated a positive family history. There was a higher than expected frequency of first degree relatives affected with OCD. In addition, this study may support the hypothesis that OCD and tics are genetically related.

OBJECTIVE: The aim of this study was to investigate the impact of self-rated stigma and functioning in patients with bipolar disorder in Latin-America. METHODS: Two-hundred and forty-one participants with bipolar disorder were recruited from three Latin American countries (Argentina, Brazil, and Colombia). Functional impairment was assessed with the Functioning Assessment Short Test (FAST) and experiences with and impact of perceived stigma was evaluated using the Inventory of Stigmatizing Experiences (ISE). RESULTS: Higher scores of self-perceived stigma were correlated with lower scores of functioning. After multiple regression analysis, being on disability benefit, current mood symptoms and functioning were associated with self-perceived stigma. CONCLUSIONS: This is the first study to demonstrate an association between stigma and poor functioning in bipolar disorder. Possible implications of such findings for practitioners are discussed. LIMITATIONS: The main limitation of this study is that the Inventory of Stigmatizing Experiences has not yet been validated in a population of bipolar patients in our countries. The sample size and heterogeneous clinical subjects from different countries and cultures limit the generalization of the present findings.
