ESSENTIALS OF DIAGNOSIS

  • Elder mistreatment may be broadly defined as any action or lack of action that leads to harm or threatened harm to the health or welfare of the elderly person.
  • Elder mistreatment includes physical or psychological abuse, caregiver or self-neglect, and financial exploitation.
  • Elder mistreatment can be committed by another person, such as a caregiver, or by self and can be intentional or unintentional.
  • The common denominator in any form of elder mistreatment is that the needs of the elderly person are unmet or have been violated.
  • The definition of elder mistreatment varies from state to state.

General Considerations

Elder mistreatment is a complex phenomenon and a major public health issue. It comprises neglect, abuse, and financial exploitation. Epidemiological studies reveal prevalence rates of 1.3-5.4%. However, many of these studies were based on self-reporting and, therefore, may underrepresent the actual prevalence rate. The National Elder Abuse Incidence Study estimated that at least one-half million community-dwelling elders were abused or neglected or experienced self-neglect during 1996. This study revealed that almost 80% of cases of elder abuse, neglect, and self-neglect were unreported. Lack of awareness (especially among health care professionals), social isolation, and the elderly person's fear of threatening the relationship with the caregiver and feeling that there is nowhere else to go, that nothing can be done to help, or of shame in admitting abuse by one's own family are some barriers to reporting elder mistreatment. Two or more types of mistreatment often coexist, and evidence of mistreatment is not always clear-cut. Regardless of the type of mistreatment, family members comprise a large portion of the mistreaters.

Nursing home residents have all the same risk factors for mistreatment as community-dwelling elders and are often so cognitively impaired that they cannot report abuse. They are also frequently physically impaired and cannot defend themselves. Multiple reports describe nursing home abuse. The 1998 compilation of complaints received by the State Long-Term Care Ombudsman program (whose aim is to “identify, investigate, and resolve individual and systems level complaints” that affect residents in nursing homes and residential care facilities) and its parent agency, the Administration on Aging, found that, nationwide, physical abuse was 1 of the 5 most frequent complaints in nursing homes. Ten percent, or ~20,000, of the complaints received by ombudsmen during fiscal year 1998 were about abuse, gross neglect, or exploitation, whereas another 5% related to financial abuse and misappropriation of property. Ombudsmen reported >1700 cases of sexual abuse of nursing home residents during a 2-year period. Because the number of people in nursing homes is increasing, the number of abuse cases in nursing homes will undoubtedly increase as well.

  • NEGLECT

Neglect is the failure of a caregiver to provide adequately for the needs of the elder. Neglect is the most common form of elder mistreatment, representing almost 70% of all cases of mistreatment in the United States. Neglect can be committed by a caregiver and can be unintentional, if the caregiver is unaware of the needs of the elder, or intentional, if the caregiver willfully fails to provide care. Self-neglect occurs when the

P.415


older person is unable to perform basic daily tasks of self-care as a result of mental or physical impairment. Diogenes syndrome is a term used to describe situations in which an elderly person lives in squalor and isolation, refusing help from the outside world.

  • ABUSE

Abuse can be physical, psychological, or sexual. Physical abuse includes hitting, pinching, kicking, and inappropriate use of restraints. Psychological abuse includes verbal aggression or making threats, which lead to emotional distress. Physical, sexual, and psychological abuse can be a part of intimate partner violence or spousal abuse.

  • FINANCIAL EXPLOITATION

Exploitation occurs when resources of an elderly person are used illegally or improperly for monetary or personal gain. The clinician must determine whether there is an explicit agreement between the patient and caregiver when money or property is being exchanged. Many elders who are lonely or who have functional but not mental limitations may knowingly enter into agreements in which personal care or friendship is traded for money, goods, or property. In other circumstances, perpetrators use undue influence by gaining a victim's confidence and then systematically isolating the victim from family and friends. These perpetrators then have the elder transfer assets into their possession. Financial exploitation when the patient has the capacity to understand the consequences of his or her actions is theft.

Clinical Findings

  1. SYMPTOMS & SIGNS

If the presence of elder mistreatment seems likely based on screening, the clinician should look for specific clinical findings. Although seemingly obvious, these findings can be missed if the clinician is not mindful of the possible diagnosis. Red flags for possible elder mistreatment are presented in Table 40-1.

The clinician should observe the patient-caregiver interaction. A mistreated elder may display behavioral problems. The caregiver may be outwardly hostile toward the patient or the health care provider.

Table 40-1. Red flags for possible elder mistreatment.

Delay in presentation for medical care after an onset of illness or injury
Frequent emergency room visits
Conflicting stories between the caregiver and the elder
Repeated injuries (“accident prone”)
Missed appointments or “doctor shopping”
Medication noncompliance

A unifying feature of abuse, neglect, and exploitation is a state of vulnerability. This vulnerability appears to be largely due to neuropsychiatric disease, which is seen in a significant percentage of mistreated elders. The most common neuropsychiatric diagnoses include dementia, depression, psychosis, and alcohol abuse. These disorders limit the patient's ability to care for self and can lead to a failure to fulfill major role or societal obligations. Abuse of substances such as prescription medication or illegal drugs may produce similar consequences. The associated behavior patterns and loss of decision-making capacity resulting in self-neglect place older persons at risk of becoming victims of crime.

  1. Physical abuse—Patients who are physically abused may have lacerations or bruises in multiple sites, fractures in unusual locations such as distal fractures of the femur, burns from cigarettes or hot liquids, or evidence of restraints on the wrist, waist, neck, or legs. Physically abused patients may display behavioral problems, such as agitation or fear of strangers.
  2. Sexual abuse—Victims of sexual abuse may present with oral venereal lesions. Bruising of the uvula, the palate, and the junction of the hard palate may indicate forced oral copulation. In addition, the clinician may note bleeding and bruising of the anogenital area as well as bruising on other areas of the body, especially the abdomen. New diagnoses of sexually transmitted disease in nursing home residents or other elders may indicate abuse. Urinary tract infections in unusual clusters have been described in nursing home residents who have been victims of sexual abuse. Difficulty sitting and walking may indicate sexual abuse in elderly women. Behavioral signs indicating potential sexual abuse may include withdrawal, fear, depression, anger, insomnia, increased interest in sexual matters, or increased sexual or aggressive behavior.
  3. Neglect—The diagnosis of neglect can be much less obvious than physical or sexual abuse. Therefore, potential

P.416


signs and symptoms of neglect must be considered in conjunction with the patient's overall health, comorbid conditions, and functional and nutritional status. Pressure ulcers, malnutrition, and dehydration are often signs of caregiver neglect. They can also occur in the absence of neglect as a result of immobility and illness. However, multiple deep pressure ulcers or malnutrition and dehydration, arising in situations in which care should be provided, can be considered clinical findings of neglect.

Patients who neglect themselves often fail to seek medical care. When they do consult a physician, findings include poor hygiene and advanced medical disease. Self-neglecting patients often dress in dirty clothes, bathe infrequently, and have ungroomed, matted hair. Skin infestations from lice, fleas, and scabies are common, as are multiple skin excoriations from scratching.

  1. Financial exploitation—Clinicians may detect clues to exploitation during the interview. Exploited elders may report being evicted from multiple dwellings. Poor nutritional status or medical noncompliance may occur because of lack of funds despite adequate income. The patients may fail to pay bills or maintain their health insurance. A new caregiver can appear on the scene to handle financial matters.
  2. PHYSICAL EXAM

Comprehensive physical examination should include a thorough skin, oral, and musculoskeletal evaluation. Nutrition and volume status should be assessed through physical examination and laboratory tests.

  1. ASSESSMENT OF HOME ENVIRONMENT

Evaluation of the home environment is important to assess fully the patient's functional capabilities. Visiting nurses, adult protective services (APS) specialists, and medical teams that make house calls can perform in-home assessments. These professionals can make observations about patient-caregiver interaction, food supplies, and the upkeep and cleanliness of the home. In-home assessments reveal information about the ability of the patient to perform activities of daily living beyond what can be learned during an office visit.

  1. ASSESSMENT OF RISK FACTORS

Potential risk factors that pertain to the elderly victim include advanced age, female gender, poverty, cognitive or functional impairment (especially recent decline), minority ethnic or racial group, and depression. Risk factors pertaining to caregivers include depression, external stress such as sudden change in economic status, alcohol and other substance abuse, history of violence, and dependency on the elder for finances or housing. Although some elders are at higher risk for mistreatment, it is important to note that elder mistreatment can happen to any elder regardless of age, gender, and race or socioeconomic status.

  1. SCREENING

Screening for elder mistreatment is essential, particularly in older persons who are cognitively impaired or unwilling to file a report. Elders are often reluctant to reveal abusive situations because they may feel humiliated or responsible. They may be afraid of threatening their relationship with the caregiver. They may be averse to pressing charges against their own family members. One study noted that 72% of elder abuse victims did not complain of the abuse at the time of presentation to an emergency center. The American Medical Association (AMA) recommends screening of geriatric patients if physical signs are present regardless of whether they complain of abuse. Screening for elder mistreatment should be a part of the routine health assessment for all older persons and part of comprehensive geriatric assessment.

Ideally, the health care provider has developed good rapport and is trusted by the elderly patient before addressing the issue of mistreatment. Patients and caregivers must be interviewed separately. One may start with general statements regarding safety in the house and with caregiving concerns. Direct questions must then be asked regarding abuse, neglect, and exploitation, using plain language in an unintimidating, nonconfrontational, and nonjudgmental manner (Table 40-2). If injury or harm has occurred, one must determine the frequency, severity, and location. A detailed social history must be obtained, including living arrangement, family composition, nonfamily member support, and socioeconomic status. This information will be helpful in formulating the management options.

Table 40-2. Direct questions about mistreatment

Do you have frequent disagreements with your son or daughter?
When you disagree, what happens? Are you yelled at?

Are you ever slapped, punched, or kicked?
Has anyone ever threatened you or made you feel afraid?
Has anyone ever made you sign a document that you did not understand

Numerous types of screening tools relevant to elder abuse and neglect exist, but most professionals collect information on the observations of others and assess risk factors. If the screening test suggests abuse, tools for performing a more comprehensive assessment for victims of elder mistreatment are available.

In some settings, such as the emergency room, comprehensive screening procedures cannot be performed because of time limitations. Instead, a single question or a 3-question screen can be used:

  1. Single-question screen. When time is limited, simply asking the patient whether he or she is being abused or neglected can be helpful.
  2. Three-question screen. Three important questions to ask when screening for elder mistreatment are as follows:
  • Do you feel safe where you live
  • Who prepares your meals
  • Who takes care of your checkbook

Differential Diagnosis

Many of the clinical features of elder mistreatment can be confused with the physical examination changes seen with normal aging.

  1. SKIN TEARS

Skin tears are lacerations seen commonly in nonabused elderly persons and occur most frequently on the forearms and occasionally on the legs. Persons usually have no more than 1-2 skin tears at a time, and skin tears often heal completely without scarring.

  1. BRUISES

Ecchymoses often occur more frequently and resolve much more slowly in older persons than in younger persons and can last for months instead of the usual 1-2 weeks.

  1. SPONTANEOUS FRACTURES

The bones of older persons are thinner and less dense, making them more susceptible to fractures as the result of bone disease or injury. Metabolic bone disease, osteoporosis and all its causes, such as chronic steroid use, osteomalacia, and Paget's disease, and cancer that invades bone make the bones more brittle. The 2 types of bone fractures known to occur spontaneously are vertebral fractures in osteoporotic older women and hip fractures.

  1. MALNUTRITION

Both smell and taste decline with age, resulting in decreased appetite. Many patients with cancer will lose weight regardless of efforts to maintain nutritional status. Poor health, including poor dentition, depression, dementia, and malabsorption syndromes, also may contribute to weight loss and undernutrition. Numerous other disorders can lead to malnutrition, including stroke, Parkinson's disease, amyotrophic lateral sclerosis, and disorders of the esophagus.

  1. DEHYDRATION

The elderly are much more prone to dehydration with minimal provocation than younger people. Dehydration is a common reason for emergency department visits by older persons. The elderly have decreased body water reserves and thirst drive; their thirst drive may remain depressed even after 12-24 h of water deprivation. The central nervous system regulation of water is altered; although antidiuretic hormone (ADH) is secreted properly in response to volume depletion, the older kidney responds less well to changes in ADH and continues to excrete water in the face of dehydration. Hydration is particularly difficult to monitor in older persons, who can experience very rapid changes in their fluid status without much in the way of symptomatology.

  1. PRESSURE ULCERS

Pressure ulcers most often occur in medically ill or cognitively impaired individuals. Intrinsic causes such as acute illness, neurological disease, peripheral vascular disease, incontinence, and poor nutritional status place individuals at higher risk. Although poor nutrition is a risk factor, improving nutritional status does not always reverse or prevent the process despite good care. Pressure ulcers may take weeks to months to heal depending on the underlying comorbidities and the extent of the lesions.

Complications

In situations of physical abuse, any of the sequelae of blunt trauma can be seen, such as broken bones, peritoneal bleeding, and organ injury as well as subdural hematomas or intracranial bleeding with head injury. Acute illnesses such as delirium, diabetic ketoacidosis, and sepsis are commonly seen in neglected elders. Because of a lack of usual medical care, neglected patients often suffer from untreated chronic illness, such as uncontrolled diabetes or hypertension, which can lead to

P.418


stroke and extensive functional limitations. Neglected patients who have i nsect infestations may have superinfected areas of skin excoriation. Pressure ulcers, malnutrition, and burns are other clinical findings that can be complications of neglect.

Treatment

Elder mistreatment is a complex medical problem that involves the domains of health, function, and social support and thus requires intervention on multiple levels.

There are no data regarding interventions in nursing home abuse. Clinicians need to understand the principles of good geriatric medical care, recognize mistreatment when it occurs, report it in accordance with the laws of each jurisdiction, and work with the facility staff to help correct problems.

  1. MEDICAL INTERVENTION
  2. History & physical—The medical approach first involves recognition of the mistreatment through the use of screening tools and comprehensive history and physical examination to look for the clinical findings. Delirium should be excluded. If the clinician suspects elder mistreatment, radiological examinations and blood tests should be ordered. Radiographs may show unsuspected fractures, often in various stages of healing. Laboratory data such as serum chemistries may reflect dehydration or electrolyte imbalance. Anemia may be present, suggesting malnutrition. Serum levels of prescribed medications may be low or undetectable, indicating that a caregiver may not be administering them. There may be high levels of sedating drugs noted on a toxicology screen.
  3. Documentation—Documentation of the abuse or neglect should be complete regardless of the health care setting. The AMA recommends specific documentation. The physician should record the chief complaint in the patient's own words if possible. Proper documentation should include a complete medical and social history. If appointments are repeatedly canceled, the name of the caller should be noted. If injuries are present, the type, number, size, location, and color as well as the patient's overall state of health, the resolution of the problems, and possible causes should be included. The physician should render an opinion on whether injuries are adequately explained by the history. All laboratory or radiological and imaging studies should be recorded. If it is possible, obtaining color photographs can be very helpful. If the police are called, the name of the officer, actions taken, and police incident number should be documented as well as the date and time the report was made to the APS and the name of the person taking the report. The diagnosis of elder mistreatment should be included in the medical problem list.
  4. Reporting—Cases of elder mistreatment are reported to the APS or a similar agency depending on the jurisdiction. Reporting requirements for physicians vary from state to state; presently all but 6 states have mandatory reporting laws. Failure to report in many instances is a misdemeanor and is punishable by law. The reporting statutes specifically state that persons whose professional communications are generally considered confidential, such as physicians, attorneys, and mental health professionals, have a duty to report and that persons filing reports of mistreatment or otherwise participating in judicial proceedings resulting from the report are immune from criminal or civil liability unless they acted in bad faith or with a malicious purpose. Even in states without mandatory reporting, a report should be filed because it can trigger social service support or legal help for the patient.

When reporting, physicians need only to provide basic demographic data, information about the nature of the mistreatment, and the demographics and names of other parties, including the alleged perpetrator, if applicable. Mistreatment that occurs in facilities such as nursing homes is handled separately in some states, and physicians should know the laws and responsible agencies in their states. The National Center on Elder Abuse web site has a complete listing of reporting laws and the telephone numbers to call for each state.

  1. Discharge or care planning—The clinician must be sure that the elder's medical and safety needs have been met. If the patient does not meet the criteria for admission to the hospital after the clinician has documented the findings and filed a report, the clinician must be sure that the home environment is safe and that there is assistance at home for functionally impaired patients. A social work consultation or consultation with an APS specialist may be necessary before discharge in order to develop a safety plan.

Elder mistreatment is often a chronic problem, and the patient should be referred to a physician or medical team with whom he or she can have an ongoing relationship. Elder mistreatment presents special difficulties for the patient in terms of function, decision-making capacity, and health and social support. These interrelated problems are best handled by a team of professionals from medicine, law, and social services. Geriatricians are skilled in the recognition of geriatric syndromes and are often very familiar with local agencies that could provide service to the mistreated elderly patient. Comprehensive geriatric assessment and intervention may be the ideal intervention for vulnerable abused or neglected elders.

P.419

 

If geriatric consultation is not available, developing a relationship with other health professionals and local agencies will be necessary to make the appropriate referrals for elder mistreatment patients. It is often helpful to discharge the patient to home with as many services as possible. Home health agencies can provide in-home assessments by social workers or nurses. Other referral sources include drug and alcohol rehabilitation services, homemaker services, and legal assistance or advocacy groups.

  1. Assessment of decision-making capacity—In many instances, the mistreated elder is vulnerable because he or she lacks the capacity to participate fully in decision making. Additionally, acute illness can reduce an older person's ability to make rational and informed decisions. Diminished decision-making capacity can have serious medical consequences when a patient with diminished capacity decides against necessary surgery or hospital transport, resulting in inadequate medical care, worsening suffering, exacerbation of an illness or injury, or even death. A competent individual has the right to be a fully informed participant in all aspects of decision making and, of course, has the right to refuse. However, those patients who lack decision-making capacity and whose expressed choices may lead to harm or even death need protection and assistance.

The determination of neglect versus poor choices hinges on an elder's capacity to participate in his or her own care. There are no easily administered standard tools that assess capacity. The gold standard is psychiatric interview, which is a process that takes time and requires a specialist, rendering it impractical in more urgent circumstances. If geriatric or psychiatric consultation is not available, the clinician should be sure that the patient understands the risks and benefits of any decisions that impact his or her health or living situation.

  1. SOCIAL SERVICE INTERVENTION

APS or some similar entity provides social intervention in almost every jurisdiction in the United States. APS specialists usually receive reports, conduct investigations, and coordinate social interventions. They elicit input from collateral sources such as friends and family members of the patient and consult with other social workers, physicians, and nurses. After the APS specialists complete the investigation and comprehensive in-home assessment of the patient's situation, they develop service plans to resolve mistreatment issues and other problems they have identified. They work closely with victims, families, and other involved parties. Their goal is to ensure that service is the least restrictive alternative, reflects the patient's preferences, and maximizes independence. When a patient has the capacity to make informed decisions, the APS specialists advocate for the right to refuse services if the individual does not want intervention. As advocates of a legal jurisdiction, APS specialists are bound by statutory limitation and may not impose services such as medical care if the patient is capable of making decisions.

  1. LEGAL INTERVENTIONS

Laws differ from state to state, but in general law enforcement is involved in cases in which crimes are committed against the elderly, such as physical abuse, neglect with malicious intent, and financial exploitation. Police officers investigate cases, looking for evidence to help prosecutors pursue perpetrators. Officers of the court and judges participate in guardianship hearings when appropriate. Members of law enforcement and the legal profession help link older persons with agencies and other resources available to victims of crime. Forensic pathologists work closely with law enforcement officers to determine the cause of death in cases of suspected homicide resulting from abuse or neglect.

Prognosis

Little is known about the natural history of mistreated elders. However, studies have shown that there is an increased mortality associated with physical abuse, caregiver neglect, and self-neglect; each is an independent risk factor. Elderly victims of mistreatment and self-neglect have significantly higher mortality than nonmistreated elders.

Lachs MS et al: The mortality of elder mistreatment. JAMA 1998;280:428. [PMID: 9701077]

EVIDENCE-BASED POINTS

  • The risk factors for elder mistreatment include age, dependency, poverty, minority race or ethnicity, and cognitive impairment.
  • The prevalence of elder abuse ranges from 1.3-5.4%.
  • Dementia and depression are more prevalent in persons reported as abused, especially those reported for self-neglect.

P.420

 

  • Persons with elder mistreatment reported to the APS have nearly triple the mortality rate of older persons never reported as mistreated.
