Evaluation of older adults usually differs from a standard medical evaluation. For older patients, especially those who are very old or frail, history-taking and physical examination may have to be done at different times, and physical examination may require 2 sessions because patients become fatigued. (For screening recommendations in older people, see Prevention of Disease in Older Adults Prevention of Disease in Older Adults Disease prevention is treatment intended to prevent a disease from occurring or worsening. Independent, older people with minimal or no chronic disease, as well as older people with several... read more .)

Older adults also have different, often more complicated health care problems, such as multiple disorders, which may require use of many drugs (sometimes called polypharmacy) and thus greater likelihood of a high-risk drug being prescribed (see table ).

Multiple disorders

On average, older patients have 6 diagnosable disorders. A disorder in one organ system can weaken another system, exacerbating the deterioration of both and leading to disability, dependence, and, without intervention, death. Multiple disorders complicate diagnosis and treatment, and effects of the disorders are magnified by social disadvantage (eg, isolation) and poverty (as patients outlive their resources and supportive peers) and by functional and financial problems.

Clinicians should also pay particular attention to certain common geriatric symptoms (eg, delirium Delirium Delirium is an acute, transient, usually reversible, fluctuating disturbance in attention, cognition, and consciousness level. Causes include almost any disorder or drug.

If patients have multiple disorders, treatments (eg, bed rest, surgery, drugs) must be well-integrated; treating one disorder without treating associated disorders may accelerate decline. Also, careful monitoring is needed to avoid iatrogenic consequences. For example, with complete bed rest, older patients can lose 1 to 3% of muscle mass and strength each day (causing sarcopenia and sharply reduced mobility), and effects of bed rest alone can ultimately result in death.

Missed or delayed diagnosis

Disorders that are common among older adults are frequently missed, or the diagnosis is delayed. Clinicians should use the history, physical examination, and simple laboratory tests to actively screen for disorders that occur only or more commonly in older patients (see table Disorders More Common Among Older Adults Disorders More Common Among Older Adults ); when diagnosed early, these disorders can often be more easily treated. Early diagnosis frequently depends on the clinician’s familiarity with the patient’s behavior and history, including mental status How to Assess Mental Status The patient’s attention span is assessed first; an inattentive patient cannot cooperate fully and hinders testing. Any hint of cognitive decline requires examination of mental status ( see Examination... read more . Commonly, the first signs of a physical disorder are behavioral, mental, or emotional. If clinicians are unaware of this possibility and attribute these signs to dementia, diagnosis and treatment can be delayed.

Polypharmacy

Patients' prescription, over-the-counter, and recreational drugs (including marijuana) should be reviewed frequently, particularly to look for drug interactions and use of drugs considered inappropriate for older patients Drug Categories of Concern in Older Adults Some drug categories (eg, analgesics, anticoagulants, antihypertensives, antiparkinsonian drugs, diuretics, hypoglycemic drugs, psychoactive drugs) pose special risks for older adults. Some... read more . This review is especially important during care transitions when reconciliation of drugs is required to eliminate duplication, missed drugs, and errors in dosage and to identify drugs that may be no longer be needed.

Caregiver problems

Occasionally, problems of older patients are related to neglect or abuse by their caregiver Elder Abuse Elder abuse is physical or psychologic mistreatment, neglect, or financial exploitation of older adults. Common types of elder abuse include physical abuse, psychologic abuse, neglect, and financial... read more . Clinicians should consider the possibility of patient abuse and drug abuse by the caregiver if circumstances and findings suggest it. Certain injury patterns or patient behaviors are particularly suggestive, including

  • Frequent bruising, especially in difficult-to-reach areas (eg, middle of the back)

  • Grip bruises of the upper arms

  • Bruises of the genitals

  • Peculiar burns

  • Unexplained fearfulness of a caregiver in the patient
