The tragedy of dementia: clinically assessing pain in the confused nonverbal elderly

Pain and cognitive status in the institutionalized elderly: perceptions & interventions

The purposes of this study were to examine the relationship between: (1) nurses' ratings of pain and corresponding administration of pain medication to elderly long-term care residents, and (2) cognitive status of the elderly and pain medication orders/administration. Participants were 83 residents, 60 years of age and older, in two groups: cognitively impaired (n = 64), and cognitively intact (n = 19). For comparison purposes, 19 of the cognitively impaired subjects were matched on age and diagnosis to provide control for potentially painful conditions. A retrospective medication review of the resident's charts was conducted to compare medication orders and administration on analgesics that were scheduled and p.r.n. (given as needed). The pain ratings of 25 RNs using a visual analogue scale were correlated with pain medications given to the resident on the day of the rating. Results indicated that RNs' ratings of resident pain and the administration of pain medications were not significantly correlated. In addition, cognitively impaired residents were prescribed significantly less scheduled medication and received significantly less pain medication (either p.r.n. or scheduled) than the cognitively intact elderly. Implications for practice and research are discussed.

Analgesic drug prescription and use in cognitively impaired nursing home residents

BACKGROUND

Prior research has documented the high prevalence of pain in elderly adults and the difficulties associated with properly assessing and treating pain in elders with cognitive impairment.

OBJECTIVES

To investigate the prescription and administration of analgesic medications to treat pain in cognitively impaired nursing home residents.

METHOD

The current sample consisted of 339 nursing home residents (295 women and 44 men) with a mean age of 87 years (range 66-104). Forty-six percent of the sample had diagnosed cognitive impairment, and 55% had at least one diagnosed painful condition. Data for this correlational study were drawn from four nursing homes in Western Pennsylvania. The Multidimensional Observation Scale for Elderly Subjects was used to assess behavioral indicators of cognitive impairment, and chart review was used to obtain demographic, medication, and diagnostic data.

RESULTS

The results indicated that cognitively impaired nursing home residents are prescribed and administered significantly less analgesic medication, both in number and in dosage of pain drugs than their more cognitively intact peers. In multiple regression analyses holding the presence of painful conditions constant, more disoriented and withdrawn residents were prescribed significantly less analgesia by physicians; more disoriented, withdrawn, and functionally impaired residents were administered significantly less analgesia by nursing staff.

CONCLUSIONS

The findings highlight the difficulties of assessing pain in cognitively impaired elders and the lack of knowledge among health care providers about effective pain management.

The impact of dementia on the pain experience

Advancing age is associated with an increased risk of illness. Investigating the influence of ageing on the experience of pain must take account of this association, as well as the impact of past experience of life. Dementia, which is almost exclusively restricted to older people, is an illness where the effects of past experience and future life anticipation are severely curtailed. The influence of dementia on the experience of pain has received little attention and many questions remain unanswered. This review draws upon this literature to describe current knowledge of the area. Suggestions for further research are made.

Assessment of acute and chronic pain in older adults

Accurate pain detection and assessment preserves functional status and independence in older adults. Pain should not be an expected outcome of the "normal" aging process. Chronic pain behaviors are less recognizable and less easily detected by health care providers and family members resulting in minimal correlation between caregiver evaluation of pain and the intensities reported by patients.

Contractures and loss of function in patients with Alzheimer's disease

OBJECTIVE

To investigate the prevalence of contractures in patients with Alzheimer's disease and to assess possible associations between contractures and cognitive and functional decline in Alzheimer's disease.

DESIGN

Case series.

SETTING

Subjects from an outpatient, university-based, dementia research center, followed, when necessary, into residential home and nursing home settings.

PATIENTS

A consecutive sample of 161 patients (48 men, 113 women; mean age 75.3 +/- 8.6 years) with a clinical diagnosis of probable Alzheimer's disease and with deficits in basic activities of daily living or more severe functional impairment.

MAIN OUTCOME MEASURES

For cognition, the Mini-Mental State Examination (MMSE); for functioning, the Functional Assessment Staging Scale (FAST); contracture is defined as a decrease of 50% or more of the normal passive range of motion of the joint.

RESULTS

Prevalence of contractures was correlated highly with degree of functional impairment (r = .70, P < .001). More than three quarters of patients who had lost the ability to walk manifested contractures; however, contractures were found in fewer than 11% of all ambulatory patients examined. When present, contractures involved more than one extremity in 97% of cases and involved all four extremities in more than two-thirds of patients.

CONCLUSION

Joint contractures are very common in the severe stages of Alzheimer's disease. More than a quarter of a million institutionalized residents in US nursing homes are likely to be afflicted by this potentially painful and disfiguring condition. Possible pathophysiology and contributing factors and possible means of intervention for this major source of disability are discussed.

Delirium in the older person with cancer

Delirium occurs in 25-40% of patients with cancer and in as many as 85% of patients with advanced cancer. Delirium, or acute confusion, can be short term and reversible and differs from dementia, which is chronic and irreversible. Accurate assessment is critical for effective treatment and to reduce the increased mortality associated with delirium. Assessment for differentiating depression as well as dementia is needed, because mistaken diagnoses often prolong and exacerbate the symptoms of delirium. Different treatment strategies are appropriate depending on the cause(s) of confusion. In this article, risk factors and assessment tools are reviewed, and interventions for delirium in older persons with cancer are presented. Future areas for research are identified, because there is a paucity of research on delirium in older patients with cancer.

The problems of pain and its detection among geriatric nursing home residents

OBJECTIVE

To assess physicians' detection of pain among geriatric nursing home residents and to determine if there are factors that may interfere with their ability to do this.

DESIGN

Chart review and patient interview.

SETTING

Geriatric nursing home.

PARTICIPANTS

One hundred nursing home residents age 65 or older. Seventy-six were communicative.

MEASUREMENTS

Demographic information, diagnoses, and medication use were compared for several groups of residents to determine their effects on the detection of pain.

RESULTS

Sixty-six percent of the communicative residents were identified as having chronic pain. Treating physicians did not detect this problem in 34% of these residents. Those whose pain was not so identified were more likely to have a neurologic disorder other than dementia. When non-communicative residents were compared with those who were communicative, the physicians were found to have identified pain less frequently in the former cohort.

CONCLUSIONS

Chronic pain is a common problem among geriatric nursing home residents and is frequently undetected. Identification of this problem among communicative residents may be markedly improved by direct questioning about this problem at frequent intervals. New methods of assessing pain need to be created to assist in its detection among the non-communicative population.
