The geriatric assessment is a multidimensional, multidisciplinary assessment designed to evaluate an older person's functional ability, physical health, cognition and mental health, and socioenvironmental circumstances. It is usually initiated when the physician identifies a potential problem. Specific elements of physical health that are evaluated include nutrition, vision, hearing, fecal and urinary continence, and balance. The geriatric assessment aids in the diagnosis of medical conditions; development of treatment and follow-up plans; coordination of management of care; and evaluation of long-term care needs and optimal placement. The geriatric assessment differs from a standard medical evaluation by including nonmedical domains; by emphasizing functional capacity and quality of life; and, often, by incorporating a multidisciplinary team. It usually yields a more complete and relevant list of medical problems, functional problems, and psychosocial issues. Well-validated tools and survey instruments for evaluating activities of daily living, hearing, fecal and urinary continence, balance, and cognition are an important part of the geriatric assessment. Because of the demands of a busy clinical practice, most geriatric assessments tend to be less comprehensive and more problem-directed. When multiple concerns are presented, the use of a “rolling” assessment over several visits should be considered.

Approximately one-half of the ambulatory primary care for adults older than 65 years is provided by family physicians, 1 and approximately 22 percent of visits to family physicians are from older adults. 2 , 3 It is estimated that older adults will comprise at least 30 percent of patients in typical family medicine outpatient practices, 60 percent in hospital practices, and 95 percent in nursing home and home care practices. 4

A complete assessment is usually initiated when the physician detects a potential problem such as confusion, falls, immobility, or incontinence. However, older persons often do not present in a typical manner, and atypical responses to illness are common. A patient presenting with confusion may not have a neurologic problem, but rather an infection. Social and psychological factors may also mask classic disease presentations. For example, although 30 percent of adults older than 85 years have dementia, many physicians miss the diagnosis. 5 , 6 Thus, a more structured approach to assessment can be helpful.

The geriatric assessment is a multidimensional, multidisciplinary assessment designed to evaluate an older person's functional ability, physical health, cognition and mental health, and socioenvironmental circumstances. It includes an extensive review of prescription and over-the-counter drugs, vitamins, and herbal products, as well as a review of immunization status. This assessment aids in the diagnosis of medical conditions; development of treatment and follow-up plans; coordination of management of care; and evaluation of long-term care needs and optimal placement.

The geriatric assessment differs from a typical medical evaluation by including nonmedical domains; by emphasizing functional capacity and quality of life; and, often, by incorporating a multidisciplinary team including a physician, nutritionist, social worker, and physical and occupational therapists. This type of assessment often yields a more complete and relevant list of medical problems, functional problems, and psychosocial issues. 7

Because of the demands of a busy clinical practice, most geriatric assessments tend to be less comprehensive and more problem-directed. For older patients with many concerns, the use of a “rolling” assessment over several visits should be considered. The rolling assessment targets at least one domain for screening during each office visit. Patient-driven assessment instruments are also popular. Having patients complete questionnaires and perform specific tasks not only saves time, but also provides useful insight into their motivation and cognitive ability.

Functional Ability

Functional status refers to a person's ability to perform tasks that are required for living. The geriatric assessment begins with a review of the two key divisions of functional ability: activities of daily living (ADL) and instrumental activities of daily living (IADL). ADL are self-care activities that a person performs daily (e.g., eating, dressing, bathing, transferring between the bed and a chair, using the toilet, controlling bladder and bowel functions). IADL are activities that are needed to live independently (e.g., doing housework, preparing meals, taking medications properly, managing finances, using a telephone). Physicians can acquire useful functional information by simply observing older patients as they complete simple tasks, such as unbuttoning and buttoning a shirt, picking up a pen and writing a sentence, taking off and putting on shoes, and climbing up and down from an examination table. Two instruments for assessing ADL and IADL include the Katz ADL scale (Table 1) 8 and the Lawton IADL scale (Table 2). 9 Deficits in ADL and IADL can signal the need for more in-depth evaluation of the patient's socioenvironmental circumstances and the need for additional assistance.

Physical Health

The geriatric assessment incorporates all facets of a conventional medical history, including main problem, current illness, past and current medical problems, family and social history, demographic data, and a review of systems. The approach to the history and physical examination, however, should be specific to older persons. In particular, topics such as nutrition, vision, hearing, fecal and urinary continence, balance and fall prevention, osteoporosis, and polypharmacy should be included in the evaluation. Table 3 is an example of a focused geriatric physical examination.

SCREENING FOR DISEASE

In the normal aging process, there is often a decline in physiologic function that is usually not disease-related. However, treatment of diabetes mellitus, hypertension, and glaucoma can prevent significant future morbidity. Screening for malignancies may allow for early detection, and some are curable if treated early. It is important that physicians weigh the potential harms of screening before screening older patients. It is essential to consider family preferences regarding treatment if a disease is detected, and the patient's functional status, comorbid conditions, and predicted life expectancy. If an asymptomatic patient has an expected survival of more than five years, screening is generally medically warranted, assuming that the patient is at risk of the disease and would accept treatment if early disease was detected. 10 , 11

The Agency for Healthcare Research and Quality has developed an online tool called the Electronic Preventive Services Selector (http://epss.ahrq.gov/ePSS/search.jsp) that can be downloaded to smartphones. It can assist physicians in identifying age-appropriate screening measures.

NUTRITION

A nutritional assessment is important because inadequate micronutrient intake is common in older persons. Several age-related medical conditions may predispose patients to vitamin and mineral deficiencies. Studies have shown that vitamins A, C, D, and B₁₂; calcium; iron; zinc; and other trace minerals are often deficient in the older population, even in the absence of conditions such as pernicious anemia or malabsorption. 12 There are four components specific to the geriatric nutritional assessment: (1) nutritional history performed with a nutritional health checklist; (2) a record of a patient's usual food intake based on 24-hour dietary recall; (3) physical examination with particular attention to signs associated with inadequate nutrition or overconsumption; and (4) select laboratory tests, if applicable. One simple screening tool for nutrition in older persons is the Nutritional Health Checklist (Table 4). 13 Table 4 Nutritional Health Checklist

note: The Nutritional Health Checklist was developed for the Nutrition Screening Initiative. Read the statements above, and circle the number in the “yes” column for each statement that applies to you. Add up the circled numbers to get your nutritional score.

0 to 2 = You have good nutrition. Recheck your nutritional score in six months.

3 to 5 = You are at moderate nutritional risk, and you should see what you can do to improve your eating habits and lifestyle. Recheck your nutritional score in three months.

6 or more = You are at high nutritional risk, and you should bring this checklist with you the next time you see your physician, dietitian, or other qualified health care professional. Talk with any of these professionals about the problems you may have. Ask for help to improve your nutritional status.

VISION

The most common causes of vision impairment in older persons include presbyopia, glaucoma, diabetic retinopathy, cataracts, and age-related macular degeneration. 14 The U.S. Preventive Services Task Force (USPSTF) found insufficient evidence to recommend for or against screening with ophthalmoscopy in asymptomatic older patients. 15 In 1995, the Canadian Task Force on the Periodic Health Examination advised primary care physicians to use a Snellen chart to screen for visual acuity, and recommended that older patients who have had diabetes for at least five years have an assessment by an ophthalmologist. Additionally, the task force advised that patients at high risk of glaucoma, including black persons and those with a positive family history, diabetes, or severe myopia, undergo periodic assessment by an ophthalmologist. 16

HEARING

Presbycusis is the third most common chronic condition in older Americans, after hypertension and arthritis. 17 The USPSTF is updating its 1996 recommendations, but currently recommends screening older patients for hearing impairment by periodically questioning them about their hearing. 18 Audioscope examination, otoscopic examination, and the whispered voice test are also recommended. The whispered voice test is performed by standing approximately 3 ft behind the patient and whispering a series of letters and numbers after exhaling to assure a quiet whisper. Failure to repeat most of the letters and numbers indicates hearing impairment. 19 As part of the Medicare-funded initial preventive physical examination, physicians are encouraged to use hearing screening questionnaires to evaluate an older patient's functional ability and level of safety. 20 Questionnaires such as the screening version of the Hearing Handicap Inventory for the Elderly accurately identify persons with hearing impairment 21 (Table 5 22 ). Additionally, patients' medications should be examined for potentially ototoxic drugs. Patients with chronic otitis media or sudden hearing loss, or who fail any screening tests should be referred to an otolaryngologist. 21 , 23 Hearing aids are the treatment of choice for older persons with hearing impairment, because they minimize hearing loss and improve daily functioning. 23

URINARY CONTINENCE

Urinary incontinence, the unintentional leakage of urine, affects approximately 15 million persons in the United States, most of whom are older. 24 Urinary incontinence has important medical repercussions and is associated with decubitus ulcers, sepsis, renal failure, urinary tract infections, and increased mortality. Psychosocial implications of incontinence include loss of self-esteem, restriction of social and sexual activities, and depression. Additionally, incontinence is often a key deciding factor for nursing home placement. 25 An assessment for urinary incontinence should include the evaluation of fluid intake, medications, cognitive function, mobility, and previous urologic surgeries. 14 The single best question to ask when diagnosing urge incontinence is, “Do you have a strong and sudden urge to void that makes you leak before reaching the toilet?” (positive likelihood ratio = 4.2; negative likelihood ratio = 0.48). A good question to ask when diagnosing stress incontinence is, “Is your incontinence caused by coughing, sneezing, lifting, walking, or running?” (positive likelihood ratio = 2.2; negative likelihood ratio = 0.39). 26

BALANCE AND FALL PREVENTION

Impaired balance in older persons often manifests as falls and fall-related injuries. Approximately one-third of community-living older persons fall at least once per year, with many falling multiple times. 27 , 28 Falls are the leading cause of hospitalization and injury-related death in persons 75 years and older. 29

The Tinetti Balance and Gait Evaluation is a useful tool to assess a patient's fall risk. 28 , 30 This test involves observing as a patient gets up from a chair without using his or her arms, walks 10 ft, turns around, walks back, and returns to a seated position. This entire process should take less than 16 seconds. Those patients who have difficulty performing this test have an increased risk of falling and need further evaluation. 31

Older persons can decrease their fall risk with exercise, physical therapy, a home hazard assessment, and withdrawal of psychotropic medications. Guidelines addressing fall prevention in older persons living in nursing homes have been published by the American Medical Directors Association and the American Geriatrics Society. 32 , 33

OSTEOPOROSIS

Osteoporosis may result in low-impact or spontaneous fragility fractures, which can lead to a fall. 14 Osteoporosis can be diagnosed clinically or radiographically. 34 It is most commonly diagnosed by dual-energy x-ray absorptiometry of the total hip, femoral neck, or lumbar spine, with a T-score of –2.5 or below. 35 , 36 The USPSTF has advised routinely screening women 65 years and older for osteoporosis with dual-energy x-ray absorptiometry of the femoral neck. 37
