Symptom Management in the Frail Elderly Population 

Dr. Katie Marchington, MD, CCFPPalliative Care PhysicianToronto Western HospitalKensington Hospice

Objectives 

• To reflect on why we should identify this population

• To develop an approach to symptom management: 

– Pain

– Delirium

• To learn through asking questions

Disclosures

• No conflicts of interest to disclose

• I will discuss the off‐label use of some medications

• Discussions relate to symptom management from a palliative care perspective

Symptom Management in the Frail Elderly Population

• Do we have to think of frail elderly patients differently than other patient populations?

– Pink‐Yes!

– Yellow‐No!

Do we have to think of frail elderly patients differently than other patient 

populations?

• Not necessarily, as long as we think of anindividualized treatment plan

• Some symptoms are more common

• Special consideration for the risk of side effects from treatments

Symptom Management: Pain

Pain Assessment: Cognitive Impairment

• Pain Assessment In Advanced Dementia Scale– PAINAD Scale

• Observational

• 5 items:1. Breathing

2. Facial expression

3. Body language

4. Negative vocalizations

5. Consolability

• Each item scored 0‐2• Total 0 (no pain) to 10 (severe pain):- 1‐2 indicates some 

pain

Available online at http://www.mhpcn.ca/uploads/PAINAD.1276125778.pdf

• Using occasional acetaminophen/Percocet with little relief, makes him drowsy

• Worried that the pain is caused by recurrence of his cancer, worried about effect on independence

Pain Assessment: Mr. B., continued

• Examination:

– Alert, attentive, answers questions appropriately

– Grimace when moving from sitting to standing, antalgic gait

– Tender on palpation over Rt iliac crest, ROM of Rthip limited in all directions by pain

‘those pills’…

Fears about opioids…

• Think, pair, share…

Fears about opioids…

• “It means the end is near”

• “Opioids cause addiction” 

• “Opioids will lose their effectiveness over time, leaving nothing to treat severe pain ‘at the end’” 

• “Opioids will make me a zombie or take away my mental capacity”

• “They will stop my breathing”

• “They will my shorten life”

Treating Pain: Principles 

• By the mouth...

• By the clock…

• With breakthroughs…

• For the individual…

• Addressing all aspects of suffering…

• Monitor treatment efficacy regularly…

• Identify and treat the underlying cause…

Treating Pain: WHO Ladder for Pain Control

Treating Pain: WHO Ladder for Pain Control

• Step 1: 1‐3/10 

– Non‐opioids: NSAIDs, acetaminophen, other adjuvants

• Step 2: 4‐6/10

– Opioids: codeine, tramadol

– Non‐opioids

• Step 3: ≥7/10

– Opioids: morphine, hydromorphone, oxycodone, fentanyl, methadone

– Non‐opioids

Treating Pain: Mr. B.

• How would you treat Mr. B.’s pain?

– Regular acetaminophen

– Dexamethasone (+ gastric mucosa protection)

– Regular and p.r.n. hydromorphone

How do we know what dose to start with?

Treating Pain: Mr. B.

• Is Mr. B. opioid‐naïve? 

– Pink‐Yes!

– Yellow‐No!

Treating Pain: Mr. B.

• Should we pick a short‐acting formulation or long‐acting formulation of hydromorphone? 

– Pink‐Short‐acting!

– Yellow‐Long‐acting!

Opioids in the Frail Elderly

• Decreased clearance and longer duration of action 

– Applies to both short‐ and long‐acting formulations

• Increased risk of neurotoxicity

• Polypharmacyrisk of drug interactions

Opioids in the Frail Elderly

• Start at a lower dose

• Consider increasing the dosing interval 

– e.g. for short‐acting opioids, q6h instead of q4h

• Titrate cautiously

Treating Pain: Mr. B.

• What dose and dosing frequency of hydromorphone?

a) 2 mg p.o. q4h

b) 0.5 mg p.o. q6h

c) 0.5 mg p.o. q6h, and 0.5 mg p.o. q2h p.r.n.

d) 0.5 mg p.o. q4h, and 0.5 mg p.o. q1h p.r.n.

What about opioid side effects?

• Constipation: Almost everyone!– Regular laxative to ensure BM at least q2‐3d

• Nausea: 2/3 patients…but it gets better!– Anti‐emetic prn e.g. metoclopramide 10 mg poq4h prn

• Sedation: Some patients…but it gets better!– Monitor

• Respiratory depression (RR < 8)– Rare if start at a low dose and titrate appropriately

Mr. B’s Individualized Pain Treatment Plan

• Non‐Pharmacological:– Education 

– Referral to spiritual care

– Radiation therapy 

• Pharmacological: – Regular acetaminophen

– Dexamethasone (+ gastric mucosa protection)

– Regular and prn hydromorphone

– Regular laxative, antiemetic prn

Dyspnea Management

• Same principles of opioid use in pain management apply to dyspnea management

• D/c home x 1 week but returned to E.D. with worsening pain, decreased mobility

…and confusion!

Delirium

• Common complication of incurable illnesses…

– Up to 85% of patients in the last weeks of life1

• …but often reversible! – Up to 50% of cases of delirium are reversible 

even in the setting of advanced illness2

Delirium

• Is distressing to patients, loved ones and caregivers 

• Alters symptom assessment and control

• Is under‐diagnosed and under‐treated

Constitutes a “medical emergency” in palliative care

Delirium

• DSM‐V Criteria:

– A disturbance in attention and awareness

– Develops over a short period of time, represents a change of baseline, and tends to fluctuate during the day

– An additional disturbance in cognition

Delirium: Common Causes

• ‘DIMS’

Treating Delirium: Non‐pharmacological

• Communication:– E.g. identify self by name at each contact

• Environment:– E.g. use calendars and clocks 

– E.g. avoid physical restraints whenever possible (use sitter or family member)

• Sound and Light:– E.g. use music which has individual significance to the patient

RNAO’s Clinical Best Practice Guidelines: Caregiving Strategies for Older Adults with Delirium, Dementia and Depression (2010)

Treating Delirium: Non‐pharmacological

• Social interaction:

– E.g. encourage family and friends to visit

• Other:

– E.g. limit choices, and offer decision‐making only when patients are capable of making these judgments

RNAO’s Clinical Best Practice Guidelines: Caregiving Strategies for Older Adults with Delirium, Dementia and Depression (2010)

Treating Delirium: Pharmacological

• Typical antipsychotic neuroleptic drug

• Regular antipsychotic is often beneficial in addition to as needed dose

– E.g. haloperidol 0.5 mg‐2mg po/subcut q8h‐q12h 

– E.g. haloperidol 0.5 mg po/subcut q2h prn

• Monitor for extrapyramidal side effects

– E.g. akathisia or ‘feeling of restlessness’

Treating Delirium: Pharmacological

• While you’re looking at medications…

– Could one the patient’s medications be exacerbating delirium?

– Is pain contributing to delirium?

– Avoid the use of opioids or benzodiazepines aloneto treat symptoms of delirium

Treating Delirium: Communication

• We know delirium is a distressing experience for caregivers…

….and this distress is reduced by educating caregivers about delirium

Treating Delirium: Communication

Treating Delirium: CommunicationMr. J’s Individualized Pain Treatment 

Plan• Treat the underlying cause (within goals of care):

– Opioid rotation from hydromorphone to fentanyl– Treatment of hypercalcemia

• Non‐pharmacological:– Calendar, identify self by name– Encourage family to visit

• Pharmacological:– Haloperidol 0.5 mg po q12h and 0.5 mg po q2h prn

• Multiple discussions with pt’s niece to explain delirium: cause, what to expect, what she can do to help patient feel calmer
