Revised by: Mary McDonald, MD (2007)
Developed by: Lynne Kallenbach, MD (2002)

 

Functional Assessment is a formalized, comprehensive review of the older person's daily activities, cognition, continence, special senses, mobility, and specific psychosocial issues.

 

Specific Learning Objectives:

A. Introduction

Before reviewing the learning objectives and content, please take the following Pre-Test.

Please review the Objectives, Content material, and Cases before our class session. We will apply the tasks in the Skills Objectives to these cases, and you should think about them ahead of time.

B. Attitudes - Third year medical students will be able to:

  1. Realize the impact functional losses can have on the life of the older patient, either individually or in combination with other functional losses or underlying medical illnesses.
  2. Realize the impact a health care provider can have on the quality of life of the older patient when appropriate attention is paid to functional matters.
  3. Realize the value of routine screening for functional losses in older patients as a preventive measure against future problems.
  4. Understand and value the need for contributions from other specialists such as physical therapists, social workers, nutritionists, etc. in the functional assessment process.

C. Knowledge - Third year medical students will be able to:

  1. Describe the components of functional assessment of the elderly patient, including comprehensive review of the older person’s daily activities, cognition, continence, special senses, mobility, and specific medical and psychosocial issues.
  2. Describe the difference between a screening tool and a diagnostic tool.
  3. Describe the screening tools most commonly used for functional assessment of the various components.

D. Skills - Third year medical students will be able to:

  1. List the components of functional assessment of the older person
    (AGING GAMES).
  2. Demonstrate the application of the screening tools used for functional assessment of the older patient (including-tests of sight, hearing, BMI, gait and range of motion, MMSE, and GDS).
  3. Integrate information gained from screening with the patient’s medical conditions into a comprehensive care plan.

E. Module Content

  1. Functional Assessment
  2. Review of Function

F. Aging Games

As you proceed through "AGING GAMES", become familiar with the methods of assessment for the various functional categories. Some of you will be asked during the discussion section to demonstrate your ability to perform a functional assessment.

H. Cases

 

I. FUNCTIONAL ASSESSMENT

When caring for older adults, physicians need to be aware of the common age and disease related disorders that can negatively affect "functional ability" (e.g., sensory, motor, and cognitive skills).

How and when a physician becomes familiar with the functional abilities of the older adult varies depending on the current health status and needs of an individual. In some situations, full interdisciplinary evaluation termed Comprehensive Geriatric Assessment is appropriate. In other situations, a brief screen of abilities by the physician, or "Review of Function" is adequate.

Comprehensive Geriatric Assessment
CGA is an interdisciplinary approach to the evaluation of an older person's physical, psychosocial and functional abilities.

Indications for CGA:

  • multiple medical problems
  • change in mental status
  • decrease in functional status
  • community-dwelling, frail elderly

Examples:

  • a 78 y/o woman with cataracts and 6 medications
  • an 82 y/o woman with history of arthritis, COPD, hypertension, CHF and recurrent urinary tract infections
  • a 72yo man who is brought in by his daughter after losing his way home several times
  • an 82yo woman who presents with functional decline and weight loss
  • Much research has gone into evaluation of CGA. Documented benefits of geriatric assessment include:
  • increased use of community services
  • more appropriate medication regimen
  • improved function
  • reduced mortality

II. REVIEW OF FUNCTION

In some patients or care settings a full assessment as described above may not be appropriate or feasible. It is still useful, however, for primary care physicians to have a method for screening older adults for common age and disease related disorders that can negatively impact function.

Outlined below are the categories that should be included in such a review of function, including what to ask and look for in your patient along with appropriate screening test to use as needed. To help you remember the categories, we have developed the mnemonic.

AGING GAMES

  • AUDIOvisual
    • Hearing loss is the fourth most common chronic disorder in the elderly.
    • 2/3 of those > 70 years of age, 3/4 of those > 80 years of age have hearing loss.
    • High frequency loss.
    • Inability to hear consonants there fore conversations are difficult to understand.
    • Can lead to withdrawal, suspiciousness, isolation, depression, and false perception by others of cognitive decline.
    • Time to treatment averages 10 years.

Assessment:

Questions to ask patient:

  1. Do you have difficulty hearing?
  2. Can you read the fine print of a newspaper?
  3. Do you have difficulty hearing in a crowd of people?

Performance tests to observe:

  1. Observation- Your own assessment of the patient's ability to hear and comprehend during your H & P is important.
  2. Otoscope- First check the external auditory canal. Very often cerumen is responsible for a conductive hearing loss.
  3. Finger rub- Rub two fingers together at each ear. Without hearing loss, this should be easily heard. A less sensitive test, but acceptable.
  4. Audiometry can be used if there is loss noted by your observation or on the finger rub test.
    • set audiometer at 40dB
    • test 500, 1,000, 2,000, 4,000 Hz F/U: Formal audiology should be recommended for patients with failure to hear 1,000 or 2,000 Hz
  • audio VISUAL
    • 90% of elderly need glasses
    • Presbyopia (decrease in near vision) is nearly universal
    • 45% of elderly have functional impairment due to vision loss

Top 4 diagnoses in elderly after presbyopia:

  • cataracts
  • macular degeneration
  • glaucoma
  • diabetic retinopathy

Assessment:

Questions to ask patient:

  1. Do you have trouble with your vision?
  2. When was your last eye exam?

Performance tests to observe:

  1. Eye chart at 20 feet with corrective lenses.
  2. Alternate- Ask the patient to read a sign on the wall and a magazine headline and sentence.

F/U: Ophthalmology for all patients unable to read all letters at 20/40 or unable to read either item.

  • GAIT

Assessment of gait involves two important areas: mobility and fall history. Keep in mind the important relationship between immobility and poor outcome.

Gait Assessment

Assessment:  

Questions to ask patient: Walking and walker

  1. Do you feel unsteady when you walk?
  2. Do you use anything to help you walk?
  3. Have you had any falls? Near falls?

Performance tests to observe:

  1. Range of motion
    • Upper extremity:
      • shoulder range of motion:
      Shoulder range of motion

Left: Subject is asked to put both hands together behind neck (External rotation)

Right: Subject is asked to place both hands together in back at waist level (Internal rotation)

Lower extremity: included in the Up and Go Test (see below)

  1. Gait and balance

    The "Get Up and Go" Test for Gait Assessment in Elderly Patients (To begin, have the patient sit in a straight-backed high-seat chair).

  • Insomnia

    • More than 50% of elderly have complaints about sleep.
    • Common diagnoses include:
    • primary sleep disorders (sleep apnea)
    • depression
    • iatrogenic and often related to medication(s)
    • related to chronic disease
    • Altered sleep cycles can negatively impact the life of the parent and caregiver, and can often lead to institutionalization.

      Assessment:

      Questions to ask patient:

      1. Do you have trouble with sleep?
      2. How many hours of sleep do you get each night?
      3. Do you nap during the day?

    F/U: Full MD evaluation and referral

  • Nutrition
    Consists of weight and dental history

    Weight

    • 15% of outpatients and 50% of inpatients are underweight
    • Weight and nutrition do not always go hand in hand!
    • You can be thin and well-nourished or heavy and malnourished.
    • Overweight can cause problems for specific health conditions, such as HTN, Diabetes and Arthritis.
    • Undernutrition - not weight alone - is linked to increased morbidity, frequent readmissions, and increased mortality.
    • Data do not support efficacy of nutritional supplementation, such as Ensure™, etc.
    • Serial weights are the most sensitive screening tool.

    Assessment:

    Questions to ask patient:

    1. "Without trying to, have you lost or gained 10 pounds in the last six months?"
    2. Do you experience any difficulty swallowing?

    Observations to make:

    1. Determine Body Mass Index (BMI)
    1. weight in kg
      height in meters2
      underweight < 22 - 24
      overweight > 28 - 30

      View Body Mass Index Calculator

    View Body Mass Index Nomogram

    1. Determine serial weights

    F/U: Significant BMIs or changes require full MD evaluation

    Dental

Patient questions:

  1. "Do you have trouble with your teeth or dentures?"
  2. "When was your last visit to the dentist?"

F/U: MD eval with dental evaluation as needed

  • GI

    • Constipation is the third most common digestive complaint in the US.
    • Highest prevalence is in those 65 years and older.
    • Complications, including bowel incontinence and electrolyte disturbances, are more common in elderly due to longstanding disease and laxative use.
    • 30-50% of those > 65 years regularly use laxatives.

    Assessment:

    Questions to ask patient:

    1. Do you have problems with your bowels?
    2. Do you ever lose control of your bowels?

    F/U: MD evaluation and referral as indicated

Top of page

 

  • GU

    • Urinary incontinence is underdiagnosed:
      • 20% of community dwelling older adults are incontinent.
      • 50% of nursing home residents are incontinent.
      • 50% can be helped with physician intervention, and without extensive testing
        • Kegel exercises, timed voids, reduced fluid intake at bedtime.

    Assessment:

    Questions to ask patient:

    1. In the last year, have you ever lost your urine and gotten wet?
    2. For men - Do you have any difficulty starting your urine stream?

    F/U: MD evaluation for positive response or symptoms of significant bother to patient.

  • Assistance, ADL/IADL's & Advance Directives

    Assistance

    • Finding out what kind of help an older person has in the home can help you understand their limitations and resources.
    • Many patients are unaware of the services they may be eligible for such as home health aides, transportation, or meals on wheels, etc.

    Assessment:

    Questions to ask patient:

    1. What help do you have at home?
    2. Who would you call on to help if you became ill?

    F/U: MD, RN, MSW refer for community based services.

    BADL/IADL's

    • Impairments = risk factors for falls and institutionalization.
    • Number or severity of medical diagnoses does not always predict functional impairment.
    • Identification of problems allows for modification before a negative outcome occurs.
    • Less than 10% of community-dwelling older adults have BADL deficits.

    Assessment:

    Basic Activities of Daily Living and Instrumental Activities of Daily Living:

  • Mood

Depression

  • Depression is one of the most common psychiatric diagnoses in the elderly.
  • It can be difficult to separate depression from dementia. Patients may present with similar cognitive deficits such as memory loss or an inability to concentrate.
  • Highest suicide risk? -- older white men
  • Clinician must maintain a high index of suspicion for depression when encountering a patient with cognitive or functional decline with unclear etiology.

Assessment

Questions to ask patient:

  • Have you been feeling sad and blue recently?
  • Do you struggle with your nerves or feel anxious?
  • IF YES, complete the Geriatric Depression Scale

F/U: Combine GDS with full MD evaluation

Top of page

 

  • Memory

Cognitive Decline

  • The prevalence of dementia increases with age, affecting up to 20 - 50% of those > 85 years of age
  • Dementia can be associated with:
    • increased use of health care services and mortality
    • high caregiver burden

Assessment:

The clinician can often uncover cognitive decline by careful observation of patients' responses curing history taking.

Questions to ask patient:

  1. Have you had trouble with your memory lately?
Performance tests to observe:
  1. Cognitive Screening tests
    • Look beyond "Alert & Oriented x 3"!
    • Initial screening test
      • Three item recall at one minute: e.g... dog, table, apple

    • Folstein Mini Mental State Exam (MMSE) if patient does not get 3/3 correct at one minute

Assessment:

Questions to ask patient:

  1. What keeps you busy during the day?

F/U: MD, RN, MSW may use to refer for community based or home resources as needed.

  • Sexuality

Sexual Function

  • Sexual activity does not have to stop as we age!
  • Change/decrease in libido is common, but overall sexual functioning is highly dependent on an individual patient's medical history.

Assessment:

  • Vision screening
    • Presbyopia and early cataracts, no intervention needed.

  • Dental screening
    • Several teeth in need of removal, poor gum health.

  • Laboratory screening
    • For weight loss of uncertain origin: CBC, Chem panel, TSH, B12, ESR, UA.  Further labs to evaluate the possibility of dementia will be further discussed in the dementia module.
