METHODS: The methodology was based on the search process described in the paper, "Bibliography of clinical research in Malaysia: methods and brief results". The search databases included PubMed, Scopus and several Malaysian journals such as MyJurnal and UKM Journal Repository, by using the following keywords: (heart valve disease OR infective endocarditis OR rheumatic heart disease) and (Malaysia).
RESULTS: In all 94 papers were identified of which 39 papers were selected and reviewed on the basis of their relevance. The local studies contributed to the knowledge and understanding of the epidemiology, aetiology, pathophysiology, clinical presentations, investigations, treatment, and outcomes of heart valve disease in the country.
DISCUSSION: The clinical relevance of the studies performed in the country is discussed along with recommendations for future research.
STUDY DESIGN: Systematic review.
METHODS: A search for relevant articles was carried out using Cumulative Index to Nursing and Allied Health Literature (CINAHL) and MEDLINE (via EBSCOhost), Scopus, Science Direct, PubMed and Google Scholar with multiple search terms. Inclusion criteria comprised articles published in English language and assessing general health literacy. Risk of bias reduced with the involvement of two independent reviewers in the screening of the literature and the quality assessment process.
RESULTS: A total of 11 studies were included, which only consist of studies from five countries out of 11 making up the Southeast Asian region. The overall prevalence of limited health literacy varied considerably, 1.6%-99.5% with a mean of 55.3% (95% confidence interval [CI]: 35.1%-75.6%). A much higher prevalence was noted in studies conducted in healthcare settings, 67.5% (95% CI: 48.6%-86.3%). The most common factors associated with limited health literacy were education attainment, age, income and socio-economic background. Other factors identified were gender and health behaviours.
CONCLUSIONS: In summary, despite the little evidence available and existences of high heterogeneity among studies, limited health literacy is still prevalent in Southeast Asian countries. Urgent strategies to improve and promote health literacy in the region are highly warranted. Besides, more studies on health literacy with better quality on the methodology aspect are needed.
