BACKGROUND Elder abuse is recognised worldwide as a serious problem, yet quantitative syntheses of prevalence studies are rare. We aimed to quantify and understand prevalence variation at the global and regional levels. METHODS For this systematic review and meta-analysis, we searched 14 databases, including PubMed, PsycINFO, CINAHL, EMBASE, and MEDLINE, using a comprehensive search strategy to identify elder abuse prevalence studies in the community published from inception to June 26, 2015. Studies reporting estimates of past-year abuse prevalence in adults aged 60 years or older were included in the analyses. Subgroup analysis and meta-regression were used to explore heterogeneity, with study quality assessed with the risk of bias tool. The study protocol has been registered with PROSPERO, number CRD42015029197. FINDINGS Of the 38 544 studies initially identified, 52 were eligible for inclusion. These studies were geographically diverse (28 countries). The pooled prevalence rate for overall elder abuse was 15·7% (95% CI 12·8-19·3). The pooled prevalence estimate was 11·6% (8·1-16·3) for psychological abuse, 6·8% (5·0-9·2) for financial abuse, 4·2% (2·1-8·1) for neglect, 2·6% (1·6-4·4) for physical abuse, and 0·9% (0·6-1·4) for sexual abuse. Meta-analysis of studies that included overall abuse revealed heterogeneity. Significant associations were found between overall prevalence estimates and sample size, income classification, and method of data collection, but not with gender. INTERPRETATION Although robust prevalence studies are sparse in low-income and middle-income countries, elder abuse seems to affect one in six older adults worldwide, which is roughly 141 million people. Nonetheless, elder abuse is a neglected global public health priority, especially compared with other types of violence.

Low‐income Latino immigrants are understudied in elder abuse research. Limited English proficiency, economic insecurity, neighborhood seclusion, a tradition of resolving conflicts within the family, and mistrust of authorities may impede survey research and suppress abuse reporting. To overcome these barriers, promotores, local Spanish‐speaking Latinos, were recruited and trained to interview a sample of Latino adults aged 66 and older residing in low‐income communities. The promotores conducted door‐to‐door interviews in randomly selected census tracts in Los Angeles to assess the frequency of psychological, physical, and sexual abuse; financial exploitation; and caregiver neglect. Overall, 40.4% of elderly Latino adults had experienced some form of abuse or neglect within the previous year. Nearly 25% reported psychological abuse, 10.7% physical assault, 9% sexual abuse, and 16.7% financial exploitation, and 11.7% were neglected by their caregivers. Younger age, higher education, and experiencing sexual or physical abuse before age 65 were significant risk factors for psychological, physical, and sexual abuse. Years lived in the United States, younger age, and prior abuse were associated with greater risk of financial exploitation. Years spent living in the United States was a significant risk factor for caregiver neglect. Abuse prevalence was much higher in all mistreatment domains than findings from previous research on community‐dwelling elderly adults, suggesting that low‐income Latino immigrants are highly vulnerable to elder mistreatment or that respondents are more willing to disclose abuse to promotores who represent their culture and community.

PURPOSE Despite growing awareness of elder abuse, cases are rarely prosecuted. The aim of this study was to examine the effectiveness of an elder abuse forensic center compared with usual care to increase prosecution of elder financial abuse. DESIGN AND METHODS Using one-to-one propensity score matching, cases referred to the Los Angeles County Elder Abuse Forensic Center (the Forensic Center) between April 2007 and December 2009 for financial exploitation of adults aged 65 and older (n = 237) were matched to a population of 33,650 cases that received usual care from Adult Protective Services (APS). RESULTS 1 Significantly, more Forensic Center cases were submitted to the District Attorneys office (DA) for review (22%, n = 51 vs. 3%, n = 7 usual care, p < .001). Among the cases submitted, charges were filed by the DA at similar rates, as was the proportion of resultant pleas and convictions. Using logistic regression, the strongest predictor of case review and ultimate filing and conviction was whether the case was presented at the Forensic Center, with 10 times greater odds of submission to the DA (Odds ratio = 11.00, confidence interval = 4.66-25.98). IMPLICATIONS Previous studies have not demonstrated that elder abuse interventions impact outcomes; this study breaks new ground by showing that an elder abuse multidisciplinary team increases rates of prosecution for financial exploitation. The elder abuse forensic center model facilitates cooperation and group problem solving among key professionals, including APS, law enforcement, and the DA and provides additional resources such as neuropsychological testing, medical record review, and direct access to the Office of the Public Guardian.

The United States is confronting two simultaneous demographic shifts with profound implications for public policy: population aging and increasing diversity. These changes are accelerating during a dramatic economic downturn, placing entitlement reform prominently on the national policy agenda. Using decennial census data from 2000, this paper examines the nexus of these trends by examining characteristics of Latino baby boomers. In the census data, Latinos constituted 10% of the 80 million boomers; roughly one-third of Latino boomers (37%) were born in the United States or abroad to a U.S. parent; 6% were born in a U.S. territory; 21% were naturalized citizens; and 36% were noncitizens. Compared to non-Latinos, Latino baby boomers had lower levels of education, home ownership, and investment income and higher rates of material hardship and poverty; however, there was considerable variation based on citizenship status. A better understanding of Latino baby boomers will help policy makers anticipate the retirement needs of baby boomers as the United States prepares for the aging of a racially and ethnically diverse population.

Objectives: The aim of this study was to examine the extent to which an Elder Abuse Forensic Center protects financial exploitation (FE) victims through referral to the Office of the Public Guardian (PG) for investigation and possible conservatorship (called ‘guardianship’ in many states). Method: Los Angeles County Elder Abuse Forensic Center cases involving adults aged 65 and older (April 2007–December 2009) were matched using one-to-one propensity-score matching to 33,650 usual care Adult Protective Services (APS) cases. The final analysis sample consisted of 472 FE cases. Results: Compared to usual care, Forensic Center cases were more likely to be referred to the PG for investigation (30.6%, n = 72 vs. 5.9%, n = 14, p < .001). The strongest predictors of PG referral were suspected cognitive impairment, as identified by APS (odds ratio [OR] = 11.69, confidence intervals [CI]: 3.50–39.03), and Forensic Center review (OR = 7.85, CI: 3.86–15.95). Among referred cases, the court approved conservatorship at higher rates – though not statistically significant – for Forensic Center cases than usual care (52.9%, n = 36/68 vs. 41.7%, n = 5/12). Conclusion: Conservatorship may be a necessary last resort to improve safety for some FE victims, and the Forensic Center appears to provide a pathway to this service. These findings suggest modification to the Elder Abuse Forensic Center conceptual model and contribute to an emerging body of evidence on the role of the Forensic Center in addressing elder abuse.

OBJECTIVES To determine the effect of a Social Health Maintenance Organization (S/HMO) on diverting older adults admitted into a nursing facility from converting to long-stay placement. DESIGN Members of the SCAN S/HMO and those in Medicare Fee-For-Service were compared on successful discharge to the community after being admitted to nursing facilities between January 1, 2001, and December 31, 2003. SETTING Skilled nursing facilities in 4 counties in Southern California (Los Angeles, Orange, San Bernardino, Riverside). PARTICIPANTS Data (N = 4635) were extracted from Minimum Data Set (MDS) 2.0 records for nursing facility residents in the S/HMO or the Medicare Fee-for-Service 5% sample who were aged 65 and older with an episode of care greater than 14 days. MEASUREMENTS Predisposing, enabling, and need measures were used to predict successful discharge to the community within 90 days. RESULTS After controlling for selected sociodemographics, comorbidities, behavioral issues, mental health conditions, and other risk factors, being enrolled in the S/HMO increased the likelihood of successful discharge by 26%. CONCLUSION With systemic increases in short-stay patients, research on diversion must look past the avoidance of unnecessary entry to nursing facilities, to the successful transition of short-stay residents to the community. As described in this study, the S/HMO model is an important but largely unaddressed method of avoiding the conversion to long-stay.

OBJECTIVE Using a socio-ecological model, this study examines the influence of facility characteristics on the transition of nursing home residents to the community after a short stay (within 90 days of admission) or long stay (365 days of admission) across states with different long-term services and supports systems. DATA SOURCE Data were drawn from the Minimum Data Set, the federal Online Survey, Certification, and Reporting (OSCAR) database, the Area Health Resource File, and the LTCFocUs.org database for all free-standing, certified nursing homes in California (n = 1,127) and Florida (n = 657) from July 2007 to June 2008. STUDY DESIGN Hierarchical generalized linear models were used to examine the impact of facility characteristics on the probability of transitioning to the community. PRINCIPAL FINDINGS Facility characteristics, including size, occupancy, ownership, average length of stay, proportion of Medicare and Medicaid residents, and the proportion of residents admitted from acute care facilities are associated with discharge but differed by state and whether the discharge occurred after a short or long stay. CONCLUSION Short- and long-stay nursing home discharge to the community is affected by resident, facility, and sometimes market characteristics, with Medicaid consistently influencing discharge in both states.

The abuse of older women appears to be a significant problem. Developing a better understanding of the extent of the problem is an important step toward preventing it. We conducted a global systematic review and meta-analysis of existing prevalence studies, in multiple languages, that occurred in the community settings from inception to June 26, 2015, in order to determine the extent of abuse against women aged 60 years and over. To disentangle the wide variations in prevalence estimates, we also investigated the associations between prevalence estimates and studies’ demographic and methodological characteristics. A total of 50 studies were included in the meta-analysis. The combined prevalence for overall elder abuse in the past year was 14.1% (95% confidence interval (CI) [11.0, 18.0]). Pooled prevalence for psychological abuse was 11.8% (95% CI [9.2%, 14.9%]), neglect was 4.1% (95% CI [2.7%, 6.3%]), financial abuse was 3.8% (95% CI [2.5%, 5.5%]), sexual abuse was 2.2% (95% CI [1.6%, 3.0%]), and physical abuse was 1.9% (95% CI [1.2%, 3.1%]). The studies included in the meta-analysis for overall abuse were heterogeneous indicating that significant differences among the prevalence estimates exist. Significant associations were found between prevalence estimates and the following covariates: World Health Organization–defined regions, countries’ income classification, and sample size. Together, these covariates explained 37% of the variance. Although robust prevalence studies are sparse in low- and middle-income countries, about 1 in 6, or 68 million older women experience abuse worldwide. More work is needed to understand the variation in prevalence rates and implications for prevention.

Elder mistreatment (EM) is a public health problem that harms millions of older Americans each year. Despite growing recognition of its occurrence, there are no evidence-based primary prevention programs. Although EM is distinct from other areas of family violence, including child maltreatment and intimate partner violence, common risk factors and theoretical underpinnings point to opportunities for prevention strategies. Drawing on evidence-based best practices found in other fields of family violence, we identify approaches that could be tested to prevent EM at the hands of family caregivers, who are among the most likely to commit mistreatment. Specifically, we examine home visiting approaches primarily used in the child maltreatment field and identify components that have potential to inform EM interventions, including prevention. We conclude that there is enough information to begin testing a prevention intervention for EM that targets caregivers.

Healthcare spending in the U.S. is at an all-time high and projected to continue rising, partly due to baby boomer aging. As most public spending for healthcare comes from general taxation revenues, the ability of the U.S. government to fund future healthcare liabilities will be determined by the economic productivity of the workforce. U.S. population growth continues to be driven by a growing Latino population, meaning taxation revenue will be dependent on incomes of an increasingly Latino workforce. Minimizing persistent economic disparities between Latinos and non-Latinos will be crucial to ensuring the economic prosperity of the Latino community and supporting U.S. economic health. After adjusting for sociodemographics, structural disparities in income for Latino baby boomers were considerably reduced but were no lower than those of the Silent Generation. These results suggest continuing investment in the Latino population, both for the advancement of Latino economic security and the bolstering of national economic growth.
