The management of elder mistreatment: the physician's role.

The physical abuse, psychological abuse, exploitation, and neglect of older adults constitute a serious and under-recognized public health problem throughout the world. Clinicians often misinterpret the health effects of elder mistreatment (EM) as caused by underlying disease or the aging process. Clues to mistreatment include the patient's appearance, recurrent urgent-care visits for the same diagnosis, missed appointments, suspicious physical findings, and implausible explanations for injuries. Avoiding confrontation and emphasizing treatment of abuse-related health conditions help the clinician maintain a therapeutic alliance with the victim and abuser. Victim safety should be the paramount concern. Victims with decisional capacity should be apprised of the chronic, progressive nature of EM. Clinical strategies to stop abuse include hospitalization and closer monitoring through office visits and home nursing. In most U.S. states, laws require that clinicians report at least physical abuse to the local adult protective services agency or to law enforcement. Mandated reporting, while offering potential social and legal remedies, raises ethical concerns regarding the physician-patient relationship.

Associations of subclinical cardiovascular disease with frailty.

BACKGROUND: Frail health in old age has been conceptualized as a loss of physiologic reserve associated with loss of lean mass, neuroendocrine dysregulation, and immune dysfunction. Little work has been done to define frailty and describe the underlying pathophysiology. METHODS: Frailty status was defined in participants of the Cardiovascular Health Study (CHS), a cohort of 5,201 community-dwelling older adults, based on the presence of three out of five clinical criteria. The five criteria included self-reported weight loss, low grip strength, low energy, slow gait speed, and low physical activity. We examined the spectrum of clinical and subclinical cardiovascular disease in those who were frail (3/5 criteria) or of intermediate frailty status (1 or 2/5 criteria), compared to those who were not frail (0/5). We hypothesized that the severity of frailty would be related to a higher prevalence of reported cardiovascular disease (CVD), as well as to a greater extent of CVD, measured by noninvasive testing. RESULTS: Of 4,735 eligible participants, 2,289 (48%) were not frail, 299 (6%) were frail, and 2.147 (45%) were of intermediate frailty status. Those who were frail were older (77.2 yrs) compared to those who were not frail (71.5 yrs) or intermediate (73.4 yrs) (p < .001). Frailty status was associated with clinical CVD and most strongly with congestive heart failure (odds ratio [OR] = 7.51 (95% confidence interval [CI] = 4.66-12.12). In those without a history of a CVD event (n = 1.259), frailty was associated with many noninvasive measures of CVD. Those with carotid stenosis >75% (adjusted OR = 3.41), ankle-arm index <0.8 (adjusted OR = 3.17) or 0.8-0.9 (adjusted OR = 2.01), major electrocardiography (ECG) abnormalities (adjusted OR = 1.58), greater left ventricular (LV) mass by echocardiography (adjusted OR = 1.16), and higher degree of infarct-like lesions in the brain (adjusted OR = 1.71), were more likely to be frail compared to those who were not frail. The overall associations of each of these noninvasive measures of CVD with frailty level were significant (all p < .05). CONCLUSIONS: Cardiovascular disease was associated with an increased likelihood of frail health. In those with no history of CVD, the extent of underlying cardiovascular disease measured by carotid ultrasound and ankle-arm index, LV hypertrophy by ECG and echocardiography, was related to frailty. Infarct-like lesions in the brain on magnet resonance imaging were related to frailty as well.

Correlates of performance-based measures of muscle function in the elderly: the Cardiovascular Health Study.

BACKGROUND: It is unknown how much age-related changes in muscle performance represent normal aging versus the effects of chronic disease and life style. We examined the correlates of four performance measures-gait speed, timed chair stands (TCS), grip strength, and maximal inspiratory pressure (MIP)-using baseline data from the Cardiovascular Health Study (CHS), a population-based study of risk factors for heart disease and stroke in persons > or = age 65. METHODS: We analyzed data from the 5,201 CHS participants. Variables were arranged into nine categories: Personal Characteristics, Anthropometry, Physical Condition, Reported Functional Status, Subjective Health, Psychological Factors, Symptoms, Cognitive Status, Habits and Lifestyle, and Prevalent Disease. Independent correlates were identified using stepwise linear regression. RESULTS: The regression models explained 17.7-25.4% of the observed variability. Although age significantly correlated with each measure, it explained little of the variability (< or = 5.7%). Anthropometric features plus physical condition explained 14.0-17.4% of the variability for grip strength and MIP, but 2.8-12.9% of the variability for gait speed and the log of TCS. Subjective health and psychological factors explained 1.8-9.4% of the variability in gait speed and the log of TCS, but < or = 1.2% of the variability in grip strength and MIP. Variables for prevalent disease explained < or = 1.3% of the variability in each measure. CONCLUSIONS: After age 64, age explained little of the variability in muscle performance in a large sample of mostly functionally intact, community-dwelling older persons. Complex measures such as gait speed were more associated with subjective factors than were direct measures of strength. Prevalent disease contributed surprisingly little to muscle performance.

Preventive health behaviors among spousal caregivers.

BACKGROUND: The physical and emotional burden of caring for a functionally impaired spouse may adversely affect the preventive health behavior of the caregiver. This study explores the relationship between caregiving and lifestyle health behaviors and use of preventive services. METHODS: The Caregiver Health Effects Study identified spousal caregivers among a sample of more than 3,000 married, community-dwelling older persons, from four counties in the United States, who were enrollees in the Cardiovascular Health Study. High-level caregivers were defined as having a spouse with an ADL impairment (n = 212) and moderate-level caregivers, a spouse with one or more IADL impairments (n = 222). For each caregiver, a control, matched for age and gender, was selected (n = 385). Structured interviews were conducted in the home, following enrollment. RESULTS: Being a high-level caregiver significantly increased the odds of not getting enough rest, not having enough time to exercise, not having time to rest to recuperate from illness, and forgetting to take prescription medications, compared with noncaregivers. These findings did not hold for moderate-level caregivers. The odds were not significantly different for either level of caregiver compared with noncaregivers for missing meals, missing doctor appointments, missing flu shots, and not refilling medications. Larger proportions of caregivers with a strong sense of control had good preventive health behaviors, compared with caregivers with a weak sense of control.

When your patient needs surgery: how planning can avoid complications.

Older patients are at high risk of perioperative morbidity due to cognitive, affective, or functional deficits. As the primary care physician, you can lower the risk of complications by taking the following steps: Eliminate medications known to cause cognitive dysfunction to help prevent postoperative confusion. Screen for postoperative delirium to identify contributing factors such as infection, whose recognition otherwise might be delayed. Assess preoperative nutritional status to identify patients with significant malnutrition, and consider nutritional repletion before elective surgery is performed. After surgery, institute timely physical therapy to prevent loss of independent ambulation or transfer in patients with borderline mobility, who are at great risk for functional decline during hospitalization. Anticipate discharge needs in collaboration with the hospital discharge planner or home health agencies.

When your patient needs surgery: weighing risks versus benefits.

The likelihood of being a candidate for elective or emergency surgery increases with age. The higher rates of perioperative morbidity and mortality seen in older patients result in part from co-existing medical illnesses. Age alone should not be a contraindication for surgery, however, and the long-term benefits of procedures such as coronary artery bypass grafting appear similar for young and old. Emergency operations account for 39 to 75% of all surgery after age 70 and carry a 20-fold increase in mortality compared with elective procedures. Appropriate surgical interventions, therefore, should not be deferred simply because the patient is elderly. Age-associated changes in body composition and organ physiology contribute to the risk of perioperative complications.

Predictors of perceived health status in elderly men and women. The Cardiovascular Health Study.

Baseline data on the perceived health status of participants (N = 5,201) in the Cardiovascular Health Study of the Elderly (CHS) are reported. The authors examined the predictive utility of health-related factors representing eight different domains, assessed gender differences in the prediction of perceived health, and tested a hypothesis regarding the role of known clinical conditions versus subclinical disease in predicting perceived health. Multivariate analyses showed that the majority of the explained variance in self-assessed health is accounted for by variables that fall into four general categories. Although gender differences were small, the analysis showed that the relative importance of several predictor variables did vary by gender.

Temporal patterns of antihypertensive medication use among elderly patients. The Cardiovascular Health Study.

OBJECTIVES: To estimate the incidence of newly treated hypertension and to describe the patterns of antihypertensive medication use among those aged 65 years and older. DESIGN: Medicare eligibility lists from four US communities (Forsyth County, North Carolina; Washington County, Maryland; Sacramento County, California; and Pittsburgh, Pa) were used to obtain a representative sample of 5201 community-dwelling elderly for the Cardiovascular Health Study, a prospective cohort study of risk factors for coronary heart disease and stroke. Participants were examined at baseline and again 1 year later. The two examinations included standardized questionnaires, blood pressure measurements, and the assessment of medication use by medication inventory. In this cohort analysis, we excluded 231 subjects (4.4%) who did not return for follow-up, 69 (1.3%) who had missing data for medications, and another 495 (9.5%) who were taking "antihypertensive" medications for an indication other than high blood pressure. INTERVENTIONS: None. RESULTS: Among the 4406 participants, 1613 used antihypertensive medications at both visits. Between the two visits, 144 started and 115 stopped antihypertensive therapy. Among nonusers at baseline, the annual incidence of newly treated hypertension was 5.2% in women and 5.6% in men. Due to the number of participants who stopped therapy, the overall prevalence of antihypertensive treatment increased only slightly, from 40.7% to 41.1% in women and from 37.1% to 38.2% in men, during 1 year of follow-up. After adjustment for age, systolic blood pressure, number of antihypertensive drugs, diabetes, and cardiovascular disease, the newly treated hypertensives were about half as likely as the previously treated hypertensives to receive diuretics (odds ratio [OR], 0.59; P = .008) or beta-blockers (OR, 0.52; P = .01); and they were about twice as likely to receive calcium channel blockers (OR, 1.88; P < .004) or angiotensin converting enzyme inhibitors (OR, 2.40; P < .001). A similar pattern of within-person changes over time was apparent among the continuous users. CONCLUSIONS: Between June 1990 and June 1991, physicians were increasingly prescribing angiotensin converting enzyme inhibitors and calcium channel blockers in place of diuretics and beta-blockers for the treatment of hypertension in elderly patients, especially for those just starting therapy.

Effects of a nursing-home respite admission on veterans with advanced dementia.

The short-term admission to a nursing home of patients with dementia represents an important respite option for their caregivers, yet little is known about how it affects the patients. Twenty-six of 39 men admitted to a Veterans Affairs dementia respite program experienced a small but statistically significant decline in self-care and behavior at 2 days after discharge, but by 14 days most had returned to their pre-respite status. Patients who deteriorated substantially had, on average, greater independence in self-care and less cognitive impairment at admission than those who improved or worsened minimally.

Clinic-based primary care of frail older patients in California.

We surveyed medical directors of primary care clinics in California to learn how those clinics cared for their frail older patients. Of 143 questionnaires sent, 127 (89%) were returned. A median of 30% of all patient encounters were with persons aged 65 or older, and a median of 20% of older patients were considered frail. A total of 20% of the clinics routinely provided house calls to homebound elderly patients. Of clinics involved in training medical students of physicians (teaching clinics), 70% had at least one physician with an interest in geriatrics, compared with 42% of nonteaching clinics (P less than .005). For frail patients, 40% of the clinics routinely performed functional assessment, while 20% routinely did an interdisciplinary evaluation. Continuing education in geriatrics emerged as a significant independent correlate of both functional assessment and interdisciplinary evaluation. Among the 94 clinics with a standard appointment length for the history and physical examination, only 11 (12%) allotted more than 60 minutes for frail patients. The data suggest that certain geriatric approaches are being incorporated into clinic-based primary care in California but do not provide insight into their content or clinical effects.

The natural history of functional morbidity in hospitalized older patients.

This study provides data on changes in the functional status of older patients that are associated with acute hospitalization. Seventy-one patients over the age of 74 admitted to the medical service of Stanford University Hospital between February and May 1987 received functional assessments covering seven domains: mobility, transfer, toileting, incontinence, feeding, grooming, and mental status. Assessments were obtained by report from the patient's caregiver (or the patient when he or she lived alone) for 2 weeks before admission; from the patient's nurse on day 2 of hospitalization and on the day before discharge; and again from the caregiver (or patient) 1 week after discharge. The sample had a mean age of 84, covered 37 Diagnostic Related Groups, and had a median length of stay of 8 days. Between baseline and day 2, statistically significant deteriorations occurred for the overall functional score and for the individual scores for mobility, transfer, toileting, feeding, and grooming. None of these scores improved significantly by discharge. In the case of mobility, 65% of the patients experienced a decline in score between baseline and day 2. Between day 2 and discharge, 67% showed no improvement, and another 10% deteriorated further. These data suggest that older patients may experience a burden of new and worsened functional impairment during hospitalization that improves at a much slower rate than the acute illness. An awareness of delayed functional recovery should influence discharge planning for older patients. Greater efforts to prevent functional decline in the hospitalized older patient may be warranted.
