Failure to Thrive Gail Wiley D.O. Candidate July 2012
Definition • National Instutitute of Aging- described FTT as “syndrome of weight loss, decreased appetite and poor nutrition, and inactivity, often accompanied by dehydration, depressive symptoms, impaired immune function, and low cholesterol”.
diagnostic criteria • there is absence of a consensus on diagnositic criteria however FTT is a syndrome of global decline defined by: • physical frailty • functional disability • neurocognitive impairment
Causes of FTT- in one retrospective chart study • Cancer 30% (n = 39) • Infection, particularly pneumonia and urinary tract infection, was found in 18% (n = 24), • Dehydration in 13% (n = 17) • Depression in 12% (n = 16). • Gastrointestinal disease (n = 15), dementia (n = 14), and substance abuse (n = 14) 11% each. • No underlying diagnoses in 5% (n = 7)
Accelerated weight loss is associated with FTT • weight loss is normal in aging • decreased olfactory sensitivity • up to ~ ½ pound per year after age 70 accelerated rate of weight loss is a significant predictor of death in nursing home patients weight loss of more than 5% of body weight in a year suggests FTT optimal BMI in elderly is higher – BMI 24-29 had less functional decline “normal” (18.5-24.9)
ADL dependency • FTT defined by loss of at least one ADL Basic ADL’s: • Personal hygiene and grooming • Dressing and undressing • Self feeding • Functional transfers (getting into and out of bed or wheelchair, getting onto or off toilet, etc.) • Bowel and bladder management • Ambulation (walking with or without use of an assistive device (walker, cane, or crutches) or using a wheelchair)
Neurocognitive Impairment Depression and Dementia leading causes of FTT Depression is treatable incidence of depression in the elderly from anywhere from 5-25% (nursing homes) incidence of dementia shown to be as high as 42% in those over 85 years of age
Laboratory Abnormalities in FTT • low cholesterol • total cholesterol less <90 is a sensitive marker for malnutrition • hypoalbuminemia • anemia • lymphopenia
Vitamin deficiency • Vit D deficiency common in elderly and associated with falls, gait imbalance and nursing home admission
Management • in order to be successful requires a multi-disciplinary approach, including • clinician • social worker • PT/OT/ speech therapy • dietician
how to treat malnutrition • add supplements between meals (Ensure) • nutritional counseling • remove dietary restrictions and make favorite foods readily available • tube feeding did not affect survival at 24 months • appetite stimulants such as Megestrol and Dronabinol may be helpful but are not well-studied and have adverse side effects- use with caution
Physical Frailty • benefit has been shown for resistance exercise- almost a two-fold increase in muscle mass • exercise and movement is imperative
Dementia • when dementia is a leading factor in FTT, changing the living situation to a higher level of assistance and supervision may be helpful • in advanced dementia FTT is inevitable as patients lose the ability to chew and swallow
Depression • a common and reversible cause of FTT in elderly • antidepressants are a mainstay of treatment, ECT is also helpful • when accompanied by psychosis, anxiety or mania- pt should be referred to a psychiatrist • Mirtazapine in particular has the added benefit of increasing appetite • low doses of Methylphenidate useful in those who are severely depressed
Something to keep in mind- medication side effects • common in elderly (decreased Cr clearance/ metabolism, polypharmacy) • updated Beers criteria suggest many common medications should be avoided in the elderly, such as: • benzodiazepines • NSAIDS • estrogen • muscle relaxers
End of Life Care • FTT is a final common pathway towards death • patients status may not be amenable to interventions and at that point it is appropriate to consider palliative care
Palliative Care • following criteria used by hospice to determine when a pt has 6 months or less to live: • weight loss not due to reversible causes • recurrent/ intractable infections • progressing dementia • progressive pressure ulcers (stage 3 or 4) despite optimal care • progressive loss of ADL’s
Summary • FTT is a nebulous diagnosis without clear diagnostic criteria or guidelines for treatment • it is an umbrella term used to describe a human’s de-evolution and regression towards death • recognizing and treating FTT is not delaying the inevitable- sometimes causes are treatable
