Geriatrics Flashcards
what causes involuntary weight loss in elderly?
social causes (difficulty shopping, meal prep), malignancy, depression, GI (malabsorption, swallowing difficulties, poor dentition), endocrine (hyperthyroid, DM2, adrenal insufficiency), advanced heart and lung dx, nutritional deficits, chronic infection (HIV), medication side effects and unknown.
How to establish involuntary weight loss?
clothing size changes or objective weight measurement
what are common causes for falls in elderly?
impaired vision and decreased proprioception.
what are the reversible causes of falls in elderly
vision, postural blood pressure, medication use, balance and gait, targeted cardiovascular and neurological examination, home hazard evaluation
How to treat vision impairment in elderly?
correction if visual acuity is <20/60
cataract removal
ample lighting without glare
How to treat postural blood pressure changes in elderly?
remove offending medication
modification of salt and fluid intake
behavioral changes (slow change in position)
compression stockings
How to treat the risk of falls from medication use?
removal of offending medications (benzos, neuroleptics, sleep aides)
reduce polypharmacy
How to treat balance and gait?
Do a get up and go test environmental modifications PT/OT for gait and balance training Assessment of assistive device exercise program
Targeted cardiovascular musculoskeletal or neurological examination
diagnose and treat underlying cause if identified
home hazard evaluation
environmental modifications (adjust poor lighting and remove loose rugs, place non slip bathmats and rails.
what is an independent predictor of functional decline and death in elderly when adjusting for depression and medical illness?
loneliness. If not addressed social isolation can lead to increased rates of anxiety, depression and suicide.
how to combat loneliness in elderly?
for pts who admit they are feeling lonely, drs need to help quality of life with interventions that decrease social isolation like social services agencies, senior center activities, volunteer work.
advanced dementia is defined by
profound memory deficits, total functional dependence, no knowledge of recent or past events, little to no verbal communication and limited ability to ambulate.
how does hospice care help pts who have advanced dementia?
they help improve quality of life experiences for patients with dementia, lower rates of hospitalization, increase likelihood of appropriate pain management and provide bereavement services to care givers.
does megestrol help with lack of appetite in dementia pts?
no
side effects of donepezil?
bradycardia, diarrhea, and nausea and vivid dreams
does artificial nutrition help with advanced dementia pts?
no it doesn’t help prevent malnutrition,
same risk for aspiration pneumonia and doesn’t improve wound healing for sacral decubitis ulcers.
Side effects of commonly used drugs in elderly:
digoxin
nausea, vomiting, cognitive impairment heart block
Side effects of commonly used drugs in elderly:
benzos
falls
Side effects of commonly used drugs in elderly:
anticholinergic medications
(including first generation antihistamines)
cognitive decline, confusion, hallucinations
dizziness, falls
urinary retention and constipation
Side effects of commonly used drugs in elderly:
opioid analgesics
constipation, sedation and confusion
Side effects of commonly used drugs in elderly:
antipsychotics:
increased mortality in pts who have dementia
community acquired pneumonia
Side effects of commonly used drugs in elderly: insulin and sulfonylureas
episodes of hypoglycemia
Side effects of commonly used drugs in elderly: fluoroquinolones
tendon inflammation and rupture
hypoglycemia
polypharmacy is defined as
> 5-10 medications and OTC supplements.
seen in older indivuals and can cause adverse drug reactions, drug drug interactions, prescribing cascades, non adherence
anti cholingergic drugs are:
amitriptyline diphenydramine meclizine oxybutynin zofran
anticholinergic side effects:
memory impairment, hallucinations, confusion, blurred vision, dry mouth, constipation, and urinary retention.
quality of life screening
screen for depression, falls, elder abuse, advanced directive driving safety, financial security cognitive impairment malnutrition hearing and vision loss bowel and bladder incontinence functional decline
screening exams for someone who’s life expectancy is >5-10 years (80 yrs)
balancing harms and benefits is a risk
Risk factors for increased driving risk in medical history:
- history of falls in the past 1-2 years
- recent accidents
- sedating medications (TCAs, anticholinergics)
- history of TIA, syncope, seizures, unstable ischemic heart dx, sleep disorders
- ETOH use
- inability to perform activities of daily living
- anxiety with driving
physical exam findings that put someone at increased risk for driving:
visual impairment >20/40 acuity in at least one eye, 120 of peripheral horizontal vision
- cognitive impairment MMSE<24/30
- decreased mobility of the head and neck
- hearing deficits
- get up and go test >15 seconds.
