Failure to thrive is defined by the Institute of Medicine as "weight loss of more than 5%, decreased appetite, poor nutrition, and physical inactivity, often associated with dehydration, depression, immune dysfunction, and low cholesterol" [6]. It is not a single disease or medical condition. Rather, it is a multidimensional problem that requires a multidisciplinary approach for its treatment. The four chief characteristics of geriatric failure to thrive are impaired physical function, malnutrition, depression, and cognitive impairment [7]. Failure to thrive is commonly used as a nonspecific diagnosis when a patient loses weight due to an unknown cause. After the diagnosis is made, it stimulates further assessment and interventions. Each of the domains of geriatric failure to thrive should be evaluated to determine areas in which the elder is having difficulty.

D) | sarcopenia. |
Cachexia is a physical wasting with weight and muscle mass loss, usually secondary to chronic progressive diseases such as cancer, acquired immune deficiency syndrome (AIDS), and chronic obstructive pulmonary disease (COPD). An estimated 10% of nursing home residents in the United States have cachexia [16]. Cachexia is a hypermetabolic state in which loss of body mass cannot be reversed nutritionally. The mechanisms that cause cachexia are poorly understood, but inflammatory cytokines and metabolic imbalances probably play a role [17,18]. Cachectic patients often have a poor prognosis due to multiple medical comorbidities. Cachexia is seen in the late stages of almost every major chronic illness, affecting an estimated 16% to 42% of people with heart failure, 30% of those with COPD, and up to 60% of people with kidney disease [18].

When caring for any patient with failure to thrive, it should first be determined if advance directives exist, and copies of any documents should be obtained. If no advance directives exist, it should be determined if the patient is capable of making his or her own healthcare decisions. This is called a determination of capacity and usually requires the signatures of two physicians. If the patient is deemed incapable of making medical decisions, the healthcare proxy will assume the role of medical decision maker. A healthcare proxy is a person that is chosen by the patient/family to make healthcare decisions for the patient. If there is not a surrogate designated, a close family member or personal friend may be appointed the proxy.
A) | signs a DNR. | ||
B) | requires antibiotics. | ||
C) | goes to the hospital. | ||
D) | is diagnosed with a terminal illness and is unable to communicate her wishes. |
The concept of living wills grew from the limitations of DNR orders. These legal documents predetermine the medical care that will be accepted and refused. It may also designate a healthcare proxy or organ donation. If lifesaving or life-prolonging treatment is warranted and the patient is unable to communicate his or her preferences, the living will is activated. The living will should be as detailed as possible, and a physician should review the contents with the patient, if possible, to ensure understanding. A nutrition/hydration directive may be created in order to ensure that a patient's/proxy's wishes regarding nutrition and hydration care are followed. This clarifies whether a feeding tube may be inserted or IV fluids administered. In some cases, patients may refuse a gastric feeding tube but allow IV hydration or blood transfusion [22].
A) | Stroke | ||
B) | Parkinson disease | ||
C) | Advanced dementia | ||
D) | Radiation therapy of the head or neck |
Gastric feeding tubes are commonly seen in nursing facilities, and they can be used for years to provide medications, hydration, and nutrition. Feeding tubes are routinely used for progressive neurologic diseases (e.g., Parkinson disease), stroke, and radiation therapy of the head or neck. However, gastric feeding tubes are not recommended for patients with advanced dementia, and there is no evidence that placement of a feeding tube improves the quality of life or survival in these patients [23,24]. Complications that can occur with a feeding tube include aspiration, infection, and tube dysfunction. In some cases, gastric feeding tubes prolong pain and suffering at the end of life. The impact of these potential complications should be considered before a gastric feeding tube is prescribed. Evidence-based information about feeding tube placement should be given to patients and family members to assist them to make informed decisions.
A) | a low-fat diet. | ||
B) | a diabetic diet. | ||
C) | fluid restriction. | ||
D) | nutritional supplements. |
Dieticians perform nutritional assessments, recommend liquid supplements, discontinue restrictive diets, obtain calorie counts, determine food preferences, recommend protein supplements, and add nutritious snacks. Dieticians or dietary technicians should evaluate a patient's nutritional status regularly: upon admission to a nursing facility, quarterly, and in case of significant change in weight.
A) | Wet voice | ||
B) | Xerostomia | ||
C) | Recurrent pneumonia | ||
D) | Coughing or choking associated with eating |
Patients often are at risk for aspiration secondary to dysphagia, and this complication is considered life-threatening. Therefore, patients with a diagnosis of dysphagia should be carefully monitored for signs of choking and/or pneumonia. Signs of dysphagia or aspiration include [31]:
Coughing or choking associated with eating
Excessive swallowing
Throat clearing
Gargling sound while eating
Wet voice
Sensation that something is stuck in throat
Food or liquid spilling from the mouth
Sneezing
Food pocketing in mouth
Recurrent pneumonia
Chest or lung congestion
Desaturation while eating

A thorough baseline evaluation is necessary for all patients with unexplained weight loss. History taking and a complete and accurate physical assessment lay the foundation for further treatment, monitoring, and follow-up. A patient's baseline physical function and health should be determined before assessing for abnormalities. Changes associated with normal aging may include loss of subcutaneous fat from face and periphery (re-deposited to the abdomen and hips), shorter stature, shrinkage of muscle mass, kyphosis, and senile ptosis or ectropion. Many geriatric patients have chronic medical conditions, and seemingly abnormal exam findings may actually reflect these long-term illnesses (Table 1) [7]. Common findings in the geriatric patient may include heart murmurs and cardiac arrhythmias, chronic skin lesions such as seborrheic keratoses, orthostatic hypotension, sensory deficit (e.g. visual, hearing), and arthritic deformities. Good history taking with input from family members and staff will help differentiate problems that require intervention from normal findings for that patient. In addition to standard physical assessment, special attention should be paid to cancer detection, as discussed, and gastrointestinal tract disorders.
A) | Kyphosis | ||
B) | Hypertension | ||
C) | Atrophic gastritis | ||
D) | Ectopic heartbeats |
Examination of the abdomen may reveal hepatomegaly, masses, constipation, distention, hernias, ascites, and tenderness. Bowel and bladder patterns and function should be assessed, using the patient's normal patterns as a baseline. Conditions such as atrophic gastritis, gastric or peptic ulcer, constipation, lactose intolerance, diverticulosis, colitis, and diabetic gastroparesis may be the cause of significant weight loss. Diagnostic approaches for abnormal exam findings may include abdominal or pelvic ultrasounds, fecal occult blood test, and kidneys, ureters, and bladder x-ray. Referral to a gastroenterologist can be crucial for patients' treatment and outcome.

Impaired physical function is one of the four domains of geriatric failure to thrive, and evaluation of physical functioning is an integral part of the geriatric evaluation [7]. It is important to determine any changes in mobility and evaluate for signs of a functional decline. This decline may be rapid, in cases of hospitalization and severe illness, or gradual, with the patient experiencing decreased mobility and independence over a period of time. Occupational therapists can provide a complete assessment of a patient's mobility and ability to perform activities of daily living (ADLs) and instrumental activities of daily living (IADL). The Katz ADL scale assesses six activities: bathing, dressing, toileting, transferring, continence, and eating [38,39]. The Lawton IADL scale assesses a patient's ability to use the telephone, shop, take transportation, manage a budget, adhere to medication regimens, cook, and perform housekeeping and laundry chores [40]. Approximately 34% of adults 65 years of age or older reported having some type of disability (i.e., difficulty in hearing, vision, cognition, ambulation, self-care, or independent living), and 49% of adults 75 years of age and older reported having difficulty in physical functioning. This ranged from 5% reporting it was very difficult (or impossible) to sit for two hours, to 33% reporting it was very difficult (or impossible) to stand for two hours [3]. For patients with failure to thrive, assessment of eating and ability to feed oneself is particularly important. Recommendations regarding contracture management and prevention, need for splints, positioning in wheelchairs or specialty chairs, and the need for assistive devices to help with eating may be made. A rehabilitation plan to assist the patient to regain independence in daily activities can be helpful.

B) | use of more than one medication. | ||
C) | use of more than five medications. | ||
D) | refusal to take multiple medications. |
Polypharmacy has been described as the use of more than 5 medications, and excessive polypharmacy is defined as the use of more than 10 medications [43]. Known hazards of polypharmacy include lack of adherence, overtreatment, adverse drug reactions (including unexplained weight loss), and incorrect dose and administration regimen. In addition to these factors, physiologic changes of aging cause differences in the absorption, distribution, metabolism, and excretion of medications [44].

The Beers list is a collection of medications potentially inappropriate for the elderly patient for a variety of reasons [45,46]. This list identifies medications not recommended for patients 65 years of age or older and identifies potentially harmful prescribing practices. Certain medications may be detrimental to elderly patients due to extended half-lives, interactions, or side effects. For example, benzodiazepines are associated with risk of cognitive impairment, delirium, falls, fractures, and motor vehicle accidents in the elderly, and before prescribing these medications, it should be clear that the potential benefits outweigh the risks [46]. Common medications on the Beers list include alprazolam, digoxin, cimetidine, diphenhydramine, lorazepam, and naproxen [45,46].
A) | Fluoxetine | ||
B) | Mirtazapine | ||
C) | Naproxen sodium | ||
D) | Diphenhydramine |
Many patients take over-the-counter allergy, cold, or cough medications as sleeping aids, some of which contain acetaminophen/diphenhydramine. Elderly patients should be advised to avoid such use, as diphenhydramine is associated with falls in this population; another sleep aid can be prescribed [46,47]. Medications that patients have taken for years may require re-evaluation if changes in health status occur.
A) | normal status. | ||
B) | mild cognitive impairment. | ||
C) | moderate cognitive impairment. | ||
D) | severe cognitive impairment. |
Cognitive impairment is another domain of geriatric failure to thrive. To fully evaluate geriatric failure to thrive, it is necessary to also assess psychologic and sociologic functioning. The Mini-Mental State Examination (MMSE) or Folstein test may be used as an objective assessment of cognition, either to establish a baseline measurement of mental status or to track progress or decline [48]. It is a 30-item exam that takes approximately 10 to 15 minutes to complete. A correct answer for each item is awarded 1 point, and a score of 25 or more is considered normal. Lesser scores can indicate severe (≤9 points), moderate (10–20 points), or mild (21–24 points) cognitive impairment. It is helpful to document serial scores in the medical record.
A) | severe depression. | ||
B) | cognitive impairment. | ||
C) | positive for depression. | ||
D) | negative for depression. |
The Geriatric Depression Scale (GDS) is a self-report measure of depression that may be utilized to screen for depression in elderly patients (Figure 3) [7,54,55]. The shortened version (GDS-S) consists of 15 questions (taken from the long form) that assess mood and hopelessness. The GDS-S can be completed in five to seven minutes, which makes it ideal for patients who are easily fatigued or limited in their ability to concentrate for longer periods of time [55]. A score of 5 or greater on this test is considered positive. If a test is positive, referral to a psychiatrist specializing in geriatric patients should be made, as these patients do respond to depression treatment (e.g., psychotherapy, pharmacotherapy).

D) | stop the offending medication. |
There are multiple long-term complications associated with typical and atypical antipsychotic medications, including pharmacokinetic and pharmacodynamic changes, limitations, and cardiovascular and other adverse effects (e.g., gastrointestinal, liver) [76]. A patient may develop a Parkinsonian syndrome secondary to long-term antipsychotic use, resulting in dysphagia, tremors, difficulty performing activities of daily living, and difficulty feeding, all of which can result in unintentional weight loss [76]. Prior to changing longstanding medication regimens, a geriatric psychiatrist should be consulted in order to help prevent exacerbation of the underlying psychiatric illness.
A) | Fluoxetine | ||
B) | Mirtazapine | ||
C) | Megestrol acetate | ||
D) | Diphenhydramine |
While megestrol has had some positive results for weight gain in the past, the potential drawbacks limit its use in practice. Patients with a history of thromboembolism should not receive megestrol. The Beers list includes megestrol acetate as a potentially harmful drug in the elderly, and its use should generally be avoided [81].
A) | COPD. | ||
B) | dementia. | ||
C) | thromboembolism. | ||

Despite adequate evaluation and treatment, certain patients with failure to thrive will not respond to interventions. These patients will continue to lose weight and decline. If the BMI is less than 22 and significant physical impairment is causing disability, the patient qualifies for hospice care [91]. When the patient has declined parenteral feeding or has not responded to nutritional support despite adequate caloric intake, a referral to hospice should be considered. As noted, geriatric failure to thrive is no longer an acceptable diagnosis for hospice according to CMS [4]. Instead, the underlying condition most contributory to the patient's terminal prognosis should be noted (e.g., malnutrition).
