Assistant Professor
Geriatric Medicine
77 yo man with few months of anorexia, weight loss
(10-15 #), nausea and diarrhea, malaise, fatigue, and
falls.
PMHx: paroxysmal Afib, HTN, glaucoma
Meds: Digoxin, lasix, lopressor, quinidine, ASA
VS stable except pulse 42, regular. Otherwise
unremarkable exam.
What could be cause of anorexia, wt loss, GI upset?
Adverse drug reactions are increased 2-3x in
elderly
strongly correlates with polypharmacy
increased comorbidity
drug-disease interaction
altered pharmacokinetics related to body composition
changes and hepatic/renal alterations
Adverse drug effects may be subtle
Falls
Anorexia
Cognitive Impairment
Fatigue
Urinary Incontinence
Constipation
Body composition changes
↑ body fat
↓ body water
↓ serum albumin
Changes in body composition can alter drug
distribution
Larger volume for distribution
Lipophilic
eg Diazepam, trazodone
Longer half life & duration action
Smaller volume for distribution
Hydrophilic
Eg PCN
Shorter half life & duration action
Physiological changes
Delayed gastric emptying
Slowed GI motility
Drug Absorption
Slowed rate of absorption
Lower peak concentrations
Variable transdermal absorption
CNS
Age related changes
↓ blood flow & O2
↑ BBB permeability
Increased sensitivity
Anti-cholinergics & sedating medications
Hyponatremia
thiazide diuretics
SSRI’s
high-dose narcotics
Hyperkalemia
Potassium- sparing diuretics
eg spironolactone
ACE inhibitors, ARBs
NSAIDs
86 yo female with Alzheimer disease, GERD, and arthritis is
admitted to hospital after a fall resulted in a hip fracture.
She is very lethargic on your exam and her family reports
this is a change from her normal mental status
Medications: donepezil, memantine, pantoprazole, tylenol
Plus inpatient meds – morphine, promethazine,
diphenhydramine, cyclobenzaprine
Which medications could be resulting in altered mental
status?
What is best option for her pain?
Potential Side effects
confusion, gait instability, dry mouth, constipation, urinary
retention
Medications with anti-cholinergic properties
Anti-depressants (amitriptyline)
Anti-spasmodics (oxybutynin, dicyclomine)
Anti-histamines (diphenhydramine, hydroxyzine)
Anti-emetics (phenergan)
Anticholinergic drugs
Narcotics
Benzodiazepines
L-dopa, bromocriptine
prednisone
NSAIDs
cimetidine
Warfarin
Antibiotics (FQs), herbals, and other meds may
increase bleeding risk and increase INR
SSRIs, SNRIs, tramadol, zyvox
Combination can increase risk for serotonin
syndrome
86 yo man with CHF, AFib, and Parkinson Disease is under your care in a
NH. The nursing staff asks you to write an order for a physical restraint
while he is in a wheelchair. They report that over the last 2 weeks he has
become more confused at night with restlessness and that his gait is more
unsteady. When he tries to walk, he needs the assistance of a nurse’s aide.
Medications: Furosemide, Digoxin, Levodopa-Carbidopa,
Bromocriptine, Nitrate Patch, Diazepam
What could be contributing to his gait instability?
PUD NSAIDs
BPH anticholinergics
CKD NSAIDs
Syncope or falls Benzos, antidepressants, neuroleptics,
BP meds, oral hypoglycemics
Prolonged QTc fluoroquinolones, azithromycin,
SSRIs, antipsychotics

A 65 y/o F with severe COPD is referred to palliative care clinic with
persistent complaints of dyspnea. She wears her oxygen at all times . On
exam – oxygen saturation 94%, clear lung fields bilaterally. An acceptable
quality of life for her would be to spend time with her dogs and husband
outside, without having constant dyspnea.
What should be done next in the management of this patient’s dyspnea?
a.
b.
c.
d.
Explain to her that oxygen saturation is in the mid 90’s and she does
not need to worry
Recommend addition of spironolactone
Recommend morphine immediate release elixir 2.5-5 mg every 4
hours as needed
Recommend she increase her oxygen from 2 to 4 liters
Palliative care
Goals
Relieve physical/emotional suffering, optimize function,
assist with MDM for pts with advanced dz
May be provided regardless of whether the patient is
receiving curative or disease-modifying treatment
Hospice
Comprehensive care for pts with life expectancy ≤6
months
Dyspnea
Opioids*
Oral & parenteral effective
Nebulized morphine not shown to be helpful

If no bowel movement for ≥4 days – check for
impaction/obstruction & consider enema
opioid-induced constipation
Methylnaltrexone
A 94 y/o F with moderate dementia, vision/hearing impairment was
hospitalized for CAP. She was started on Levaquin and 2 days into
her admission began “talking out of her head” according to her
family, which is a change from her baseline.
On exam - T 37.3C, BP 108/56 mmHg, HR 95/min, RR 16/min, O2 sat
94% on ambient air, thin, inattentive, lungs with rhonchi over
posterior right base (unchanged from admit), no focal deficits. All
home meds were continued on admission including: omeprazole,
rivastigmine, lorazepam PRN.
LABS normal serum electrolytes/glucose
Cr 1.4 (up from 1.2 on admission)
CBC with WBC 10 (down from 14 on admission)
UA negative
Which of the following would be the
best next step?
A
B
C
D
E
Haloperidol, restrain for safety
Change antibiotics, bedside observer
Olanzapine, head CT
Risperidone, EEG
Short acting benzodiazepine, head CT
~1/3 hospitalized elders have delirium
50% present on admission
Prevalence increased in ICU & hospice settings
May persist for weeks to months in subset
Older, dementia, functional impairment, multiple comorbidities; restraint use & delirium severity
Independently associated with poor patient
outcomes
Increased risk of death, institutionalization, & dementia
Confusion Assessment Method (CAM)
Most useful bedside assessment tool
Requires presence of 1 + 2 + (3 or 4)
1.
2.
3.
4.
Acute change in mental status & fluctuating course
Inattention
Disorganized thinking
Altered level of consciousness
CAM - ICU
Designed for non verbal/vent dependent pts
Sensitivity lower than traditional CAM
Under-recognition is HUGE
Standardized screening of ICU, post-op, very elderly pts
Daily; aids in recognition of hypoactive delirium
Baseline risk
Advanced age
Dementia
Impairment with ADLs
High medical comorbidity
Lab abnormalities
Dehydration, sodium, thyroid
Some evidence
Males, sensory impairment (hearing, vision), depression,
alcohol abuse
Acute risk
Medications
sedating, anticholinergic
withdrawl
Indwelling devices &
Surgery
Uncontrolled pain
Anemia
Bed rest
restraints
Infection
Stroke
MI
Urinary retention
Fecal impaction
FIRST STEP
Take a history – patient, support staff, family
Includes chart review
Full physical exam
THEN Targeted labs, imaging, other diagnostics
REMEMBER
Typically multiple contributing factors
Medications
BEERS Criteria
Effect OR withdrawl
Infections
Fluid balance
Dehydration, heart failure
Electrolyte Disturbances
Sensory deprivation
Eyeglasses, hearing aids/amplifiers
Elimination issues
Fecal impaction, urinary retention
Impaired CNS oxygenation
Anemia, hypoxia, hypotension
Severe pain
ALL
CBC, chem8
Consider
UA, UDS, LFTs, ABG
CXR, EKG, cultures, troponin
EEG if seizure activity
LP if meningitis suspected
Head CT/Brain MRI
if head trauma suspected or focal findings on neuro exam
Behavioral Interventions
Family visitation
Daily reorientation
Sleep-wake schedule
Avoid unnecessary interventions at night
Limit tethers & ties
Pharmacologic Intervention
Low dose, short term antipsychotics
Haldol, risperidone, olanzapine, seroquel
Remember to check EKG to evaluate QT interval
What do I do if they have prolonged QT interval??
Remember to taper off as soon as possible
Avoid 1st generation antipsychotics in LBD & PD
Opt for seroquel
Ativan – IF benzo or ETOH withdrawl
Urinary incontinence
Scheduled toileting program
Immobility/Falls
Physical therapy – MOBILIZE THAT PATIENT
Avoid restraints – they are NOT your friend
Opt for 1:1 sitter
Pressure ulcers
Mobilization – can I hear it again?!
Repositioning if immobile
Monitor pressure points
Sleep disturbance
Sleep hygiene is your best option
Feeding disorders
Assist with meals
Aspiration precautions
Nutritional supplements at snacks
Environment

Hospital Elder Life Program (HELP)
Interventions/Risk factors
Cognitive impairment
Sleep deprivation
Immobility
Visual/Hearing impairment
Dehydration
A 75-yo M is admitted to rehab after having a stroke 2 wk ago. He has residual right-sided
paralysis, aphasia & urinary incontinence. He spends most of the day in bed or in a chair and
needs assistance with all ADLs. The patient has a poor appetite, cannot use his right arm to
feed himself, and is eating only half his meals. He also has intermittent urinary incontinence.
Which of the following is the most appropriate intervention for preventing pressure ulcers in this
patient?
A
B
C
D
E
An air-fluidized bed
A doughnut cushion when seated
A foam mattress overlay
Bladder catheterization
Massage of skin over pressure points
Any process rendering immobility for extended time
period
Intrinsic risk factors
Age, poor nutritional status, decreased arteriolar blood
pressure
Extrinsic risk factors
Friction, shear, moisture, urinary or fecal incontinence
Skin care (Limited evidence)
Daily skin inspection
Skin cleaning with mild agent; Moisturizer
Do NOT massage over bony prominences
Avoid skin exposure to wound drainage, urine, feces,
perspiration
Nutrition (inconsistent studies)
Do NOT OVER-supplement pts with protein, vitamin,
mineral supplements
evidence is lacking if no deficiency
Optimal nutrition is part of national pressure ulcer
prevention guidelines
Mechanical off-loading
Minimize friction/shear
Reposition q2H
Use of bed positioning devices
Do NOT use seating cushions (ie doughnuts)
Support surfaces (pressure redistribution device)
Use with any pt at risk
No one surface superior but all superior to standard mattress
Two types of devices
Static: foam, static air, gel/water
Dynamic: alternating air, low air loss, air fluidized
Which to use?
Static is less expensive so used in most
Use dynamic IF:
“bottoming out” (surface compressed to <1 inch)
Reactive hyperemia despite static support use
Dynamic airflow potential adverse effects
Dehydration, sensory deprivation, difficulty with mobilization
Suspected Deep Tissue Injury
Purple with intact skin/blister
Stage I
Non blanching erythema
Stage II
Partial thickness loss of dermis
Stage III
Full thickness tissue loss
Stage IV
Exposed bone, tendon, or muscle
Suspected Deep Tissue Injury
Purple with intact skin/blister
Stage I
Non blanching erythema
Stage II
Partial thickness loss of dermis
Stage III
Full thickness tissue loss
Stage IV
Exposed bone, tendon, or muscle
A 77-year-old F is transferred to SNF after a 2-wk hospital stay for hip fracture repair. Her
hospital course was complicated initially by a lower gastrointestinal hemorrhage and
subsequent bacteremia from an intravenous line.
Her vital signs are within normal limits. She is alert and oriented to person and date. She appears
thin. She has a 4 x 5 cm pressure ulcer over her presacral area that extends through the skin,
but no muscle or bone is exposed. The ulcer is debrided with little exudates. There is minimal
surrounding erythema.
Which of the following is indicated for the pressure ulcer?
A
B
C
D
E
Calcium Alginate dressing
Hydrocolloid dressing
Short course of systemic antibiotics
Silver sulfadiazine cream
Vacuum-assisted closure device
Location
Drainage
Stage
Necrosis
Area
Granulation
Depth
Cellulitis
Transparent film
i.e. tegaderm
Stage I & II
c/i if draining or suspected infection
Foam island
i.e. allevyn, lyofoam
Stage II & III; with lo-mod exudate
c/i if excessive exudate or dry/crusted
Hydrocolloids
i.e. duo-derm, tegasorb
Stage II & III; with lo-mod drainage
Good for autolytic debridement
remains in place 3-5 days
c/i poor skin integrity, infection, packing
Alginate
i.e. AlgiDERM, Sorbsan, Algosteril
Stage III, IV; excessive drainage
c/i dry/min drainage, superficial with maceration
Hydrogel
Gel or sheet – Intrasite, vigilon, restore
Stage II, III, IV
c/i macerated, excess exudate
Gauze packing (moistened with saline)
Stage III/IV
c/i deep wounds, tunneling
Silver dressings
ie aquacel Ag, silvadene
Malodorous wounds; hi exudate; suspected local infection; slow healing
c/i systemic infection, cellulitis, fungus, skin necrosis, leukopenia,
interstitial nephritis
Recommendations
Wet-to-dry discouraged
Hydrocolloid preferred
Require fewer dressing changes; block bacteria; maintain
moist environment
Pick a dressing based on stage, amount of wound
exudate, suspected infection
Performed if necrotic, devitalized tissue present – as it prevents healing
Four types
Mechanical: wet-to-dry, hydrotherapy
Can remove vitalized tissue; painful
Enzymatic: topical agent
Use if no infection present; damage surrounding skin
Autolytic: synthetic dressings allow self digestion
Use if no infection present & no other method tolerated; takes longer for effect
Sharp: scalpel, scissors, forceps, laser
Quick, effective; use if infection present
Biosurgery: Maggot or larva therapy
Good for those who cannot tolerate surgery
Surgical Repair
Viable option for stage III & IV ulcers
Types
Direct closure, skin grafting, skin flaps, musculocutaneous flaps, free
flaps
Diet/Nutritional Supplements
Controversial; limited evidence
Dietary recommendations –
30-35 calories/kg/d
1.25-1.5g of protein/kg/d
Amino acids may assist
Argine, glutamine, cysteine
New problem – blame a drug
Falling elders – give vitamin D, order PT, home
safety evaluation (OT)
Preferred drugs
Anti-depressants
Citalopram, escitalopram, remeron, sertraline
Pain medication
Tylenol, tramadol
Insomnia
Zolpidem, trazodone, remeron
