Q

Reasons for prevalence of DRP (elderly > youths)

A
  1. Cognitive impairment
    a. Short term memory loss
    b. Cognitive impairment
    = Poor safety awareness, poor historian, confused state
    = Require hx from gamily
  2. Presentation of medical symptoms differs in elderly
    a. Infections (not febrile –> change in behaviour, confused, slower to respond, drowsy, FALL)
    b. MI, stroke (not chest pain –> stomach pain, nausea, drowsy)
  3. Prevalence of SE
    a. More likely to be affected by SE, more receptor sensitive
    b. Changes in PK, PD
    = antiHTN: Postural hypotension
    = Antidep: SIADH

Q

Pharmaceutical care checklist:
help pt achieve what matters to them most by address DRP

A

1) Present medications are appropriate - CURRENT MEDS

2) Appropriate medications present - CORRECT MEDS

3) Appropriate medications reach the patients - ADHERENCE
- Failure to receive drugs
□ Appropriate drug
□ Non-adherence/ poor technique
□ Storage (bisphosphonate, INHaler)
□ Inappropriate use (INH)
□ Intrinsic: Health beliefs, ignorance, cognitive impairment.

Q
  1. what maters most/ impt to pt
A
  • Needs and wants – to patient and caregiver
  • Consider inpatient vs ambulatory

(inpatient) : stabilise pt, vital signs, maintain disease state, maximal function

(ambulatory): needs and wants, QOL, prevent complications/ flares/ freq/ SE/ improve condition/ ADLs

Q
  1. Explicit criteria/ HIGH alert medications
A

Explicit criteria: drugs that are more likely to cause harm than benefit
* guidelines (BEERS, FRIDs, STOPP, STOPPFrail, STOPPFall)

HAM: commonly associated with adverse events in patients, deemed as greater risk
* Insulin, opioids, anticoagulants, concentrated electrolytes, cytotoxic/ chemotherapeutic agents

Q
  1. Implicit criteria – clinical judgement
A

Q

Any new symptom in older patient should be considered a possible DRUG SIDE EFFECT!!!!!!

why is this important?

A

Prevent prescribing cascade

  • Using a another drug to treat the SE of another drug as belif is from new medical problem
    ○ Contribute to poly-pharmacy
    ○ Look for pseudo-indication (Opposing pharmacology, MOA)

  • Spironolactone and hydrocortisone
  • Anticholinergic and acetylcholine inhibitors
  • NSAID and hypertensives

Q

comprehensive geriatric assessment is for

A

Beneficial for older adults cfs4 - cfs7(based on frail scale + ADL & iADL)

  • Not helpful for older patients who are very fit (CFS1-3)
  • or severely frail – irreversible and life-limiting pathology (CFS8-9)

Q

CGA comprise of 5 aspects

A
  1. functional status
  2. medical review
  3. mental cognition/ mood
  4. medication/ nutrition
  5. socioeconomic resources
17
Q

similar to 4M

A

what matters (share with care team)

medication (HAM)

mentation (delirium, depression. hydrate. orientate TIME, PLACE, SITUATION, sleep)

mobility (any limitations, ensure early, freq, safe mobility)

18
Q

what is CGA for?

A

Comprehensive geriatric assessment (CGA) is defined as a multidisciplinary diagnostic and treatment process that identifies medical, psychosocial, and functional limitations of a frail older person in order to develop a coordinated plan to maximize overall health with aging.

diagnostic, evaluation and management

19
Q
  1. functional status (CGA)
A
  • Pt QOL, preferences, values
    ○ Maximise pt function by ensuring other factors (below) are met.
    ○ Because pt function deficit may not be reversible, only maintained
  • ADLs, iADL
  • Develop interventions to maintain or improve functional independence and enhance QOL
20
Q

CFS

A

1-3: very fit to managing medical problems well

4-6: living with very mild/ mild/ moderate frailty

7-9: living with severe frailty. terminally ill

21
Q

CFS 4-6

A

4: previously vulnerable. not dependent for daily help, but sx limit activities

5: need help with IADL (SHAFTTT)

6: need help with IADL, some help with ADLs

22
Q

ADL (DEATH)

A

Dressing, Eating, Ambulating, Toileting, Hygiene

23
Q

iADL (SHAFTTT)

A

Shopping, Housekeeping, Accounting, Food prep, Taking meds, Telephone, Take transport

  • Require higher mental function to perform
  • Compare from baseline to see if they have the functions to begin with (eg not everyone knows how to cook)
24
Q
  1. medical review
A
  • Conduct: conduct detailed ROS to identify any medical prob
  • Assess and address: chronic conditions that impact pt overall health
  • Identify potential geriatric syndromes (falls, incontinence, polypharmacy)
  • Tailor (medical interventions to optimise overall well being and QOL)
25
Q

common geriatric syndromes

A

impaired mobility, instability (falls)
UI
cognitive impairment (dementia, delirium)
frailty
sarcopenia

polypharm and iatrogenic disease
pressure areas
malnutrition

26
Q

consideration for medication management in older persons

A
  • altered PK, PD
  • older persons atypical presentation
  • higher prevalence of multimorbidity and polypharm
  • incr susceptibility to ADR, DDI, DDI
  • diff goals of care
  • modified tx targets
  • impaired functional capacity and cognitive decline
27
Q
  1. Mental (cognition/ mood)
A
  • If cognitive impairment present –> determine etiology
  • Evaluate mood and emotional status to identify signs of depression/ anxiety
  • Consider impact of cognitive and mood status on medication adherence and self-care
28
Q

delirium/ dementia / depression

A

deirium - dementia:
* monitor longitudinally
* pt hx (baseline cognitive function, acute or chronic sx)

depression:
* try tx with antidep and MONITOR any improvement of sx

29
Q
  1. medication/ nutrition
A
  • Review pt medication regimen, address DDI & DFI
  • Assess nutritional status and identify for deficiencies or malnourishment
  • Optimise medication and nutrition plans to enhance pt outcomes and reduce ADE-
30
Q
  1. socioeconomic resources
A
  1. Identify pt social support system and available resources
  2. Evaluate pt living conditions and potential safety concerns
  3. Address financial barrier and consider the impact on pt’s health management
  4. Advanced care preferences
31
Q

ABCDEF framework for CGA

A

○ Accurate diagnosis of dementia
○ Behavioural and psychological symptoms (BPSD – progression of disease)
○ Caregiver stress (pt abuse)
○ Drug and disabilities
- What can pt do - we try to maintain function
-What drugs may affect pt function vs what drugs pt NEED

○ End of life discussion and equipment
- Equip to assist caregiver
- Equip for safety
○ Financial supports

32
Q

summary of frameworks

A
  • appropriateness of medication px (MAI)
  • identify DRP (pharmaceutical care)
  • geriatric CFS 4-7 (CGA)

(use PCF, MAI to achieve care goals of CGA)
(use PCF for older pt not considered primary beneficiary for CGA)

(CGA 5 components: if older person not under care of geriatrician)
(all CGA, ABCDEF: if CFS)

33
Q

medication use principles for older persons

A
  • start LOW, GO SLOW
  • non-pharm tx to minimise unnecessary polypharm
  • use meds with lowest risk of ADE (BEERS etc)
  • least n.o. of meds
  • monitor for ADE, atypical presentation
  • review meds regularly
34
Q

polypharm and deprescribing

A

not without harm

  • no valid, current indication
  • contribute to ADR, geriatric syndromes
  • due to prescribing cascade* high risk in the pop
  • ineffective
  • for preventive indication in pt with LIFE-LIMITING ILLNESS (bisphosphonate at EOL)
  • unaccceptable tx burden
35
Q

deprescribe plan

A
  • prioritise by greatest risk/ cocerns to pt
  • develop plan (tapering if risk of adverse drug withdrawal reactions)
    * BB, CS, BZP, APS, opioids, PPI, antiparkinson, antidep, antiseizure
  • self-monitoring (counsel) and FU
