Interventions for preventing abuse in the elderly

BACKGROUND

Maltreatment of older people (elder abuse) includes psychological, physical, sexual abuse, neglect and financial exploitation. Evidence suggests that 10% of older adults experience some form of abuse, and only a fraction of cases are actually reported or referred to social services agencies. Elder abuse is associated with significant morbidity and premature mortality. Numerous interventions have been implemented to address the issue of elder maltreatment. It is, however, unclear which interventions best serve to prevent or reduce elder abuse.

OBJECTIVES

The objective of this review was to assess the effectiveness of primary, secondary and tertiary intervention programmes used to reduce or prevent abuse of the elderly in their own home, in organisational or institutional and community settings. The secondary objective was to investigate whether intervention effects are modified by types of abuse, types of participants, setting of intervention, or the cognitive status of older people.

SEARCH METHODS

We searched 19 databases (AgeLine, CINAHL, Psycinfo, MEDLINE, Embase, Proquest Central, Social Services Abstracts‎, ASSIA, Sociological Abstracts, ProQuest Dissertations & Theses Global, Web of Science, LILACS, EPPI, InfoBase, CENTRAL, HMIC, Opengrey and Zetoc) on 12 platforms, including multidisciplinary disciplines covering medical, health, social sciences, social services, legal, finance and education. We also browsed related organisational websites, contacted authors of relevant articles and checked reference lists. Searches of databases were conducted between 30 August 2015 and 16 March 2016 and were not restricted by language.

SELECTION CRITERIA

We included randomised controlled trials (RCTs), cluster-randomised trials, and quasi-RCTs, before-and-after studies, and interrupted time series. Only studies with at least 12 weeks of follow-up investigating the effect of interventions in preventing or reducing abuse of elderly people and those who interact with the elderly were included.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the studies' risk of bias. Studies were categorised as: 1) education on elder abuse, 2) programmes to reduce factors influencing elder abuse, 3) specific policies for elder abuse, 4) legislation on elder abuse, 5) programmes to increase detection rate on elder abuse, 6) programmes targeted to victims of elder abuse, and 7) rehabilitation programmes for perpetrators of elder abuse. All studies were assessed for study methodology, intervention type, setting, targeted audience, intervention components and intervention intensity.

MAIN RESULTS

The search and selection process produced seven eligible studies which included a total of 1924 elderly participants and 740 other people. Four of the above seven categories of interventions were evaluated by included studies that varied in study design. Eligible studies of rehabilitation programmes, specific policies for elder abuse and legislation on elder abuse were not found. All included studies contained a control group, with five of the seven studies describing the method of allocation as randomised. We used the Cochrane 'Risk of bias' tool and EPOC assessment criteria to assess risk of bias. The results suggest that risk of bias across the included body of research was high, with at least 40% of the included studies judged as being at high risk of bias. Only one study was judged as having no domains at high risk of bias, with two studies having two of 11 domains at high risk. One study was judged as being at high risk of bias across eight of 11 domains.All included studies were set in high-income countries, as determined by the World Bank economic classification (USA four, Taiwan one, UK two). None of the studies provided specific information or analysis on equity considerations, including by socio-economic disadvantage, although one study was described as being set in a housing project. One study performed some form of cost-effectiveness analysis on the implementation of their intervention programmes, although there were few details on the components and analysis of the costing.We are uncertain whether these interventions reduce the occurrence or recurrence of elder abuse due to variation in settings, measures and effects reported in the included studies, some of which were very small and at a high risk of bias (low- and very low-quality evidence).Two studies measured the occurrence of elder abuse. A high risk of bias study found a difference in the post-test scores (P value 0.048 and 0.18). In a low risk of bias study there was no difference found (adjusted odds ratio (OR) =0.48, 95% 0.18 to 1.27) (n = 214). For interventions measuring abuse recurrence, one small study (n = 16) reported no difference in post-test means, whilst another found higher levels of abuse reported for the intervention arms (Cox regression, combined intervention hazard ratio (HR) = 1.78, alpha level = 0.01).It is uncertain whether targeted educational interventions improve the relevant knowledge of health professionals and caregivers (very low-quality evidence), although they may improve detection of resident-to-resident abuse. The concept of measuring improvement in detection or reporting as opposed to measuring the occurrence or recurrence of abuse is complicated. An intervention of public education and support services aimed at victims may also improve rates of reporting, however it is unclear whether this was due to an increase in abuse recurrence or better reporting of abuse.The effectiveness of service planning interventions at improving the assessment and documentation of related domains is uncertain. Unintended outcomes were not reported in the studies.

AUTHORS' CONCLUSIONS

There is inadequate trustworthy evidence to assess the effects of elder abuse interventions on occurrence or recurrence of abuse, although there is some evidence to suggest it may change the combined measure of anxiety and depression of caregivers. There is a need for high-quality trials, including from low- or middle-income countries, with adequate statistical power and appropriate study characteristics to determine whether specific intervention programmes, and which components of these programmes, are effective in preventing or reducing abuse episodes among the elderly. It is uncertain whether the use of educational interventions improves knowledge and attitude of caregivers, and whether such programmes also reduce occurrence of abuse, thus future research is warranted. In addition, all future research should include a component of cost-effectiveness analysis, implementation assessment and equity considerations of the specific interventions under review.

Best-Practice Guideline on the Prevention of Abuse and Neglect of Older Adults

A systematic review of the literature was conducted to identify effective approaches to preventing and addressing abuse and neglect of older adults within health care settings in Canada. The review was conducted using databases searched from January 2000-April-May 2013. Additionally, expert panel members submitted article citations from personal archives. Two research associates (NRA) screened each title and abstract for inclusion. After inter-rater reliability was determined between the NRAs (Kappa score of 0.76), the records were divided, appraised, and data extracted independently. The review resulted in 62 studies that focused on identifying, assessing, and responding to abuse and neglect of older adults; education, prevention, and health promotion strategies; and organizational and system-level supports to prevent and respond to abuse and neglect. Abuse and neglect of older adults remains under-explored in terms of evidence-based studies; consequently, further research in all of the areas described in the results is needed.

Governmental efforts to improve quality of care for nursing home residents and to protect them from mistreatment: a survey of federal and state laws

There are many federal and state laws addressing, directly and indirectly, the quality of care provided to nursing home residents and the protection of residents from mistreatment. They include: (a) state laws that govern the licensing of nursing homes, (b) federal laws that govern the certification of nursing homes for participation in the Medicare and Medicaid programs, (c) elder abuse laws prohibiting mistreatment of older adults in nursing homes and other settings, (d) health care fraud abuse laws that are increasingly being used to combat the provision of substandard care to Medicare and Medicaid beneficiaries in nursing homes, and (e) laws that have established long-term care ombudsman programs to promote the health, safety, well-being, and rights of nursing home residents. While these laws are generally viewed as having improved the care and treatment of nursing home residents, much remains to be done, particularly with respect to the implementation of these laws.

Definitions and indicators of elder abuse: a delphi survey of APS caseworkers

Instruments designed to measure specific types of elder mistreatment are not available, but they may be warranted after an initial screen indicates abuse or risk for abuse. The purpose of this study was to evaluate definitions for different types of elder mistreatment and validate the indicators as perceived by adult protective services (APS) caseworkers' opinions. Through 351 APS research network participants, a Delphi survey was completed. A 45% return rate was achieved for round one and 40% for round two with 70 same respondents from both rounds. These types of abuse, emotional abuse, exploitation of finances and/or property, neglect, physical abuse, and sexual abuse, have some similar and some extremely different indicators that singly and together expand their definition. Instruments to measure five different types of abuse are offered for caseworker or prevalence study use.

Elder abuse and neglect

In the past 10 years, reports of the abuse of older adults have risen by 30%. Supported by a growing body of work, research, practitioner and policy communities are poised to confront the problem. This article represents a review of the elder abuse and neglect literature published since 2001. Literature on elder abuse and neglect tends to be grouped in the following categories: definitional issues; screening and assessment instruments; the scope of elder abuse and neglect; sexual abuse; risk factors; outcomes; studies of Adult Protective Services; multidisciplinary teams; interventions by medical, criminal justice and policy communities; long-term care facilities; and theoretical perspectives. The authors suggest that studies of elder abuse and neglect move beyond descriptive studies and include more nuanced statistical methods and mixed methods approaches, further explore the promising research design of crosslinking a variety of databases, include a theoretical underpinning and work toward more theorizing, explore incidence and prevalence approaches to eventually capture elder abuse and neglect on a national level, and focus on outcomes of interventions (e.g., education, agency/entity).

Association of knowledge of adult protective services legislation with rates of reporting of abuse in Iowa nursing homes

OBJECTIVE

To determine if there is an association between abuse reporting to state authorities by nursing home administrators and directors of nursing and their characteristics and knowledge of the law.

DESIGN

Survey.

SETTING

Iowa's 409 Medicare certified nursing homes.

PARTICIPANTS

Four hundred nine administrators and 409 directors of nursing.

MEASUREMENTS

Nursing home abuse incidents, reports, and substantiations, Medicare's Nursing Home Compare Reports, Urban Influence Codes, and county census demographics.

RESULTS

A single or double response was received from 369 (90%) of the 409 nursing homes. Being a male administrator and having a higher level of education is associated with higher substantiation rates. A greater knowledge of the dependent adult protective services law is associated with higher incident and report rates for directors of nursing.

CONCLUSIONS

Nursing home administrators' and directors of nursing's knowledge of the law and their characteristics are associated with nursing home incident, report, and substantiation of abuse allegations.

APS workers job requirements associated with elder abuse rates

The purpose of this paper is to evaluate the relationship of required educational background of APS workers to the 1999 rates of domestic elder abuse. Data were obtained from APS related statutes and regulations and questions to the National Center for Elder Abuse list serve. Descriptive statistics and independent sample t-tests were used for analyses. Those states whose legislations required a social work degree for APS caseworkers did have higher elder abuse investigation rates. A lower substantiation ratio was found for those states requiring a social work degree or license. These findings suggest that social work education may lead to an emphasis on investigation and interventions and de-emphasis on the criminal aspects of elder abuse evaluation substantiations.
