Abstract
ABSTRACT Objective: This study comprises a systematic review and meta-analysis that aimed to estimate the prevalence of dementia in long-term care institutions (LTCIs). Methods: We used the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). Original transversal and longitudinal articles published until July 2020 were eligible in this review. Databases PubMed/MedLine, Web of Science, Scopus and ScienceDirect were searched. Overall prevalence and confidence intervals were estimated. Heterogeneity was calculated according to the index of heterogeneity (I2). Results: One hundred seventy-five studies were found in all databases and 19 studies were meta-analyses, resulting in an overall prevalence of 53% (CI 46-59%; p < 0.01) of demented older adults living in LTCIs. Conclusion: Prevalence of dementia is higher in older adults living in LTCIs than those living in general communities. This data shows a worrying reality that needs to be changed. There is a need for a better understanding of the elements that cause this increase in dementia in LTCFs to direct actions to improve the quality of life and health of institutionalized elderly.
Highlights
Dementia is a syndrome characterized by poor cognition and functional decline[1]
This review encompassed original articles published in peer-reviewed and indexed journals until July 2020, in any language, which analysed the prevalence of dementia in long-term care institutions (LTCIs) or those with quantitative data that allowed for the calculation of the proportion of people with dementia
The articles must present the instruments and criteria used for the diagnosis of dementia or the strategies used to calculate the prevalence of dementia in LTCIs, such as MEEM, Clinical Dementia Rating (CDR), Montreal Cognitive Assessment (MoCA), DSM criteria, and the analysis of medical records
Summary
Dementia is a syndrome characterized by poor cognition (e.g., impaired memory, language, executive function, attention and visuospatial perception) and functional decline[1]. Due to demographic and health transitions, the number of people with dementia in Latin America will increase from 7.8 million in 2013 to over 27 million by 2050. Possible causes of this increase in dementia in developing countries are limited access to primary care, low education and a high incidence of curable diseases such as systemic arterial hypertension and syphilis. In Brazil, the prevalence of dementia is 7.1% in people aged 65 and over[3] This condition affects about 50 million people worldwide[4] and is a major cause of death and disability among older adults[5]
