Prevalence of Elder Abuse and Neglect of Persons with Dementia in Community Settings: A Systematic Review and Meta-Analysis.

INTRODUCTION

Individuals with dementia are at an elevated risk for abuse and neglect. This study aimed to estimate pooled prevalence rates of elder abuse among community-dwelling individuals with dementia using a meta-analytic approach. Additionally, it explored the heterogeneity associated with prevalence estimates through subgroup analyses.

METHODS

In line with the Cochrane guidelines, searches were conducted across eight academic online databases, reference lists of eligible studies, and existing systematic reviews. Eligible studies are studies published between January 1990 and March 2023 that report elder abuse among people with dementia (PWD) in community settings. The final review included 30 eligible studies from eight countries, encompassing a sample of 6,789 dependent/carer dyads.

RESULTS

The pooled rate of overall abuse among older adults with dementia is 42.6% (95% CI: 0.34-0.51). Among the various forms of abuse, psychological abuse was most prevalent, occurring in 44.8% of cases (95% CI: 0.37, 0.52), followed by financial abuse (28.3%, 95% CI: 0.03, 0.53), neglect (19.8%, 95% CI: 0.09, 0.34), and physical abuse (10%, 95% CI: 0.07, 0.13).

CONCLUSION

The high prevalence of elder abuse highlights the significant vulnerability of individuals with dementia. The highest rate of psychological abuse indicates a particular need to address emotional trauma of PWD, as well as to adopt measures to reduce abusive or neglectful behaviors via caregiver education and support.
